Tesla battery: device, characteristics, condition. Tesla is secretly creating a new generation of low-voltage batteries Tesla batteries
In the spring of 2015, Tesla showed the public a new battery for home use. This marks a new stage in the development of the corporation. This battery is like a worm on the way to the creation of a smart home, which is not dependent on external communications.
History of creation
The generation and generation of electrical energy in the 21st century is one of the most important problems. It contains a wealth of prospects for all humanity. Traditionally, the use of electrical energy comes in two ways:
- commercial (processing of coal, naphtha, gas, nuclear energy, natural water and solar energy);
- non-commercial (processing of industrial outputs, firewood, vigor of meat).
Moreover, commercial generators account for over 90% of the total electricity supply. This trend has been observed for dozens of years, regardless of the current crisis of burning resources and cloudy atmosphere. If we do not begin to correct the situation, then an energy crisis or a global environmental disaster may occur. Therefore, the Tesla company decided to make its contribution from the development of an innovative battery system.
The project to create a unique Tesla battery was carried out by Elon Musk himself, who can be considered a revolutionary in the sphere information technologies. To be honest, almost no one believed in the success of electric vehicles for another 10 years. However, through the efforts of Elon Musk, he was able to create the popular electric car Tesla Model S, which every motorist would want to buy. It turned out that despite the monopoly of the engines of internal combustion, an alternative to the rare fire had been found a long time ago. It’s just that no one dared to change tired traditions. After the success of electric cars, Tesla decided to start developing the consumer battery.
The decision about this was presented on the 30th quarter by Elon Musk himself. Such a revolutionary development may not only have a positive impact on the public sector, but also on the economy. New battery names Tesla Powerwall. We will allow you to change the amount of carbon dioxide released into the atmosphere and therefore reduce your energy costs. So, in essence, the Tesla company has taken up the continuation of the idea of autonomous power supply, which is no longer unique. Even today, many Vlasnik households cover the doors of their lives with solar panels, like living with lead-acid batteries. Tesla's new battery is much more efficient and economical.
Characteristics of Powerwall batteries
A Powerwall battery can capture energy from solar panels as well as other energy sources. The system can have a capacity of 7 or 10 kW. Obviously, the first option is suitable for saving stagnation, and the other is for building energy reserves. The average American family, who lives in an enclosed three-bedroom house and a working Tesla battery, uses approximately 3,200 kW per year. Therefore, by recharging the battery, you can protect such an alarm for about 4-5 years.
It is reported that the installation of Tesla batteries will be carried out simultaneously from the Solar City company. This company is engaged in the production and installation of solar batteries, and its largest shareholder is the brilliant Elon Musk. In the future, it is planned to involve other partners who will take part in the development of the project. According to financial experts, sales of new batteries could bring Tesla as much as $4.5 billion. This is due to the fact that many large companies can use new batteries for their own purposes. For them, the Powerpack system will be developed, which will include a whole set of battery units with a capacity of 100 kW per year. In commercial use, these batteries can be combined into a combustion system with a capacity of 10 MW per year or more. The Tesla company has already announced that its equipment has already begun to be tested in the American companies Walmart and Cargill.
Advantages of the Tesla Powerwall battery
Stalling of lithium-ion battery cells
The use of high-quality lithium-ion batteries provides important innovative solutions, which were used as the basis for the new Powerwall battery. This battery significantly surpasses traditional acid-lead batteries in many ways. Thus, a lead-acid battery lasts a little more than 800 discharge and charge cycles. At the same time, the lithium-ion battery lasts 1000-1200 charging and discharging cycles. In addition, the lithium-ion battery is almost always inferior to the lead one depending on its capacity.
Reception design
Despite its small size, Tesla's battery has been given a sleek and stylish design. Retailers of Tesla Powerwall believed that this product may create hostility, which could result in initial damage. This product has rounded edges and is remarkably similar to its competitors. In addition, for these rechargeable batteries, creators demonstrate the great diversity of color solutions. To that, tell us without cheers technical characteristics, Tesla Powerwall will definitely take care of your respect. This device can be mounted directly on the wall, without taking up a minimum of space.
Tsilisna ecostructure
The new Powerwall battery comes in two modifications, each with a capacity of 7 and 10 kW per year. Their risk is 3 thousand and 3.5 thousand dollars per day. In principle, if for any reason the capacity cannot be removed, then you can add more batteries to the system, increasing the storage capacity to 90 kW per year. You can connect up to 9 batteries maximum. To connect these batteries, you do not need to thoroughly learn the principles of electrical lines. Here you can solve all problems with one cable.
Effective solutions for business and industry
In parallel with the Powerwall, another system is presented, which is intended to provide electricity to industrial facilities. This new product was called Tesla Powerpack. The peculiarity of this battery lies in the possibility of an unlimited increase in potential capacity, reaching several Gigawatts per year. This battery was created under the supervision of Elon Musk, which is a sound of thinking on a large scale. Therefore, this battery was presented not so much for specific utilities, but for the entire electrification system as a whole. In order to provide the entire planet with energy, Tesla plans to create more than 900 million Powerpack batteries.
This system is about ecology in order to allow the majority of the industrial generation of electricity to be generated with the help of fossil resources. All you can do is change the types of foreign speeches of Dovkill. In addition, the Tesla Powerpack battery allows you to achieve greater autonomy for any industrial facility.
Development of capitalism in Russia
Before you add a Tesla battery, be sure to understand what is right for you. How to take a lot of stored energy for 10 kW per year, at the cost of the same amount of battery capacity per 10 kW per year. The price of a Tesla Powerwall battery is 3.5 thousand, which at the current exchange rate is approximately 175 thousand rubles. In addition, it is important to remember about the need to add an inverter, which currently costs 1.5 thousand dollars. You also don’t need to forget about the expenses that you may have to pay in electric lancet, which combines with the battery, reversing the flow of the inverter. At this rate, the total CCD of a Tesla battery is approximately 87%. Therefore, the boiler consumes not all 10 kW per year, but only 8.7 kW per year.
Under the dual-zone tariff system, the additional accumulated energy is set to 5 kW per year, which is 57% of the maximum resource of Tesla Powerwall. Reshta energy when going to the evening gathering. With such an allocation for the supply of electricity supplies, the cost per river becomes approximately 22 thousand rubles per river in the United States and less than a third less in the territory of Russia. It is also important to note that a standard lithium-ion battery typically loses approximately 6% of its capacity over time. Therefore, over time, the battery capacity gradually changes, and you will no longer be able to cope with one Tesla Powerwall battery.
It turns out that, given the current costs, the Tesla Powerwall battery in our country does not pay for itself for 15 rubles. The total cost of owning a roof without sun panels is approximately 250,000 rubles.
Think about the topic
In the opinion of many representatives, the new development of the company is a useful option that allows achieving energy independence. This device can be refurbished in the coming days, avoiding unnecessary losses from the constant deposition of natural copalins. However, today the popularity of this property must be high for it to be prominent in our country. In addition, if before the opportunity to add another price for the converter, inverter and solar panels, the situation will appear even less favorable. At the same time, there are many people who are ready to invest in their future to create a green planet in this way. For this purpose, Tesla Powerwall is best suited. In addition, you can purchase insurance to further reduce the battery life.
Of course, Elon Musk’s idea is not entirely innovative, since today there are no options for home batteries. However, in Musk’s opinion, all these batteries are too expensive, ineffective and not very reliable. Therefore, the main strategy of the Tesla company is to popularize these batteries and change their prices.
According to experts, the new Powerwall batteries may be suitable for those families and businesses that may already have solar panels installed in their homes. Musk himself notes that in California alone there are at least 300 private booths equipped with sleep systems. Therefore, all of them can easily be equipped with Tesla batteries. Also, such batteries will become an excellent option for vehicles that require constant uninterrupted food. There is a lot of concern about hospitals, military organizations, etc. Once accumulated sleepy energy can be generated Sony batteries more effective and demanded. For example, since previously many people were seen from the dormouse panels, the fragments of stench were due to the bright dormouse light, now the situation may change. Due to the use of batteries, energy can accumulate throughout the day and be consumed in the evening, which is more rational.
Nedoliky
The key disadvantage of the battery is its high voltage. In addition, you will have to pay an additional thousand dollars to install the battery. Just wait, what kind of luxury can you afford to yourselves? Therefore, according to Elon Musk, it is necessary to show people that this additional device can be completely protected. Therefore, it is necessary to change the cob yield by approximately 30%. This will be possible once the construction of the new Tesla plant near Nevada is completed. The experts are optimistic, and in their opinion, in the remaining tens of years, the amount of electrical energy is generally falling and in the near future there are no plans to change the minds to increase it These are the prices. It is not without reason that the Tesla company's development of a unique home battery will become very popular and in demand.
The main problem of electric cars is not the infrastructure at all, but the “batteries” themselves. It is not so difficult to place chargers on the skin parking lot. It is possible to completely tighten the electrical tension. If you don’t want to believe it, guess Vibukhov’s growth Stilnikov's Merezh. Operators literally in 10 years have built an infrastructure in the whole world that is much more complex and more expensive, less needed for electric cars. There will be an “endless” penny flow and prospects for development, so we can continue the topic without much fuss.A simple breakdown of the battery economy of a Tesla Model S
Let’s start by figuring out why your hot dog was chopped up. Unfortunately, on the manufacturer’s website, performance characteristics data are published for the buyer who doesn’t like to think about Ohm’s law, who happened to search for information and engage in his own rough estimates.What do we know about this battery?
There are three options that are labeled per kilowatt-year: 40, 60 and 85 kWh (40 are already taken from production).
It appears that the battery is taken from serial 18650 Li-Ion 3.7v batteries. Vibnik Sanyo (aka Panasonic), the capacity of the skin is approximately 2600mAh, and the capacity is 48g. Most of all, there are alternative supplies, although the performance characteristics may be the same, and the main mass on the conveyor is still in the form of a light leader.
(IN serial cars The folded batteries don't look like that at all =)
To say, the total battery capacity is ~ 500 kg (obviously, what is left in the capacity). We need to add a dry shell, a heating/cooling system, fuel and wiring, well, let’s say, 100 kg. We lose ~ 400 kg of batteries. With one jar of 48g, the yield is approximately 8000-10000 jars.
Let’s verify the assumption:
85,000 watt-year / 3.7 volts = ~23,000 amp-year
23000/2.6 = ~8850 cans
Tobto ~425kg
So, it’s rude to converge. We can confirm that there are ~2600mAh elements with a quantity of about 8k.
The axis i was applied to the film after the opening =). Here it is vaguely reported that the battery lasts for over 7 thousand voltages.
Now we can easily figure out the financial side of nutrition.
A skin bank for a cross-border buyer today costs ~$6.5.
To avoid being unfounded, I’ll confirm with a screenshot. Guys' sets for $13.85: 
The wholesale price from the factory will probably be twice as low. That's $3.5-4 per piece. You can buy threads for one tube (8000-9000 pieces - this is already a serious wholesale).
And it turns out that the cost of the battery cores themselves today is ~ $ 30,000. Apparently, Teslas get much cheaper.
According to the specifications of the charger (Sanyo), we have 1000 guaranteed recharge cycles. In the background it says minimum 1000, but on the right in that for ~8000 cans this will be the current minimum.
In this way, if we take the standard average mileage of a car for 25,000 km (that is, ~1-2 charges per day), we take away approximately 13 years until it is completely unusable by 100%. Albeit, half the capacity of these banks is spent after 4 days in this mode (this fact has been recorded for this type batteries). In fact, the guarantee is that the robots stink, even if the car has half its mileage. Exploitation in such a way wastes some sense.
This means that here $30-40k for 4 days of normal coasting goes into bruht. Regardless, the cost of charging looks ridiculous (there will be ~$2-4k worth of electricity for the entire life of the battery =).
Based on these rough figures, one can estimate the prospects for the production of “ICE-smerduchok” from the car market.
For a sedan similar to the Model S with an internal combustion engine for 25,000 km on the road, ~ $ 2500-3000 for gasoline. For 4 days, definitely ~ $10-14k.
Visnovki
The price of a battery will not increase by 2.5 times (and the price of fuel will not increase by 2.5 times =), it’s too early to talk about the mass depletion of the market.Prote prospects are wonderful. Battery manufacturers are increasing their capacity. Batteries will become lighter. They will have less rare earth metals.
Yak just for similar cans (3.7v) wholesale price available for capacity 1000mAh will drop to $0.6-0.5, mass revolution in electric cars will begin(Gasoline is becoming more expensive due to consumption).
I recommend monitoring and other battery form factors. It is possible that prices for them change unevenly.
I assume that such price reductions will occur even before the new revolution in chemical battery technologies. Tse will be a rapid evolutionary process that takes 2-5 years.
There is, of course, no risk of sudden displacement when using such batteries. As a result, there is a shortage of raw materials and supplies, but it seems that everything will work out. Such vests were greatly overestimated in the past, and as a result, they seemed to be getting worse.
Here is another trace great moment. Tesla doesn't just seal 8k cans into one can. The batteries go through extensive testing, are selected one by one, a bright lance is created, a sophisticated cooling system is added, a set of controllers, sensors, etc., which are not yet available to the average buyer, are filled with a high-pressure liquid. So what should I buy? new battery will be cheaper from Tesla" and save less and take all sorts of things. And it turns out that Tesla has immediately signed up all customers for consumables that cost 10 times more expensive, lower the energy charge. This is good business =).
Insha rich, competitors will appear soon. For example, BMW is already releasing an electric i-series axle-axle (more than anything, I’ll invest in BMW shares instead of Tesla for the long haul). Well, then – more.
Bonus. How will the light market change?
From the looks of it, the main reason for the production of automobiles is that they are rapidly declining. Aluminum from the internal combustion engine will migrate to the body parts, so it is no longer possible to work the bodies of electric cars (very important). Without DVZ, the required foldable and important steel components are not needed. The car (and infrastructure) will have significantly more media, more polymers, more electronics, and perhaps no steel (a minimum of traction elements + running gear and armor. Everything). You can wind the battery burners without any harshness =).Vitrate of oil, lubricant, and all sorts of additives can be reduced to zero. It’s a stinking heat as we enter history. However, more and more polymers will be needed, so Gazprom will lose the horse =). It is irrational to “spit” naphtha with zagalo. It can be used to produce solids and durable chemicals of the highest technological level. This age of carbohydrates will not end with electric cars, but reforms in this market will be serious and painful.
The new generation of Tesla batteries is being dismantled in a secret area
Oleksandr Klimnov, photo Tesla and Teslarati.com
Today's company Tesla Inc. It is working very hard on the next generation of already worn out batteries. They must save significantly more energy and at the same time become much cheaper.
New batteries may begin to stagnate on the promising Tesla pickup (a small pickup truck, which, according to other data, may become brutal, will be responsible for the displacement of the current best-seller from the market America Ford F-series)
The Californians were the ones who created the first additions to the serial production of electric vehicles, high-energy lithium-ion rechargeable batteries, thereby dramatically increasing their range. At that time, the batteries of the Roadster model, the flagship of the Tesla brand, were made up of thousands of finger-type batteries for laptops, and lithium-ion batteries are specially created for electric vehicles. They are released without detection, but Tesla’s advanced technology, as before, allows it to lose its leadership in the high-energy battery segment. However, the world began to leak the first information about the upcoming generation of Tesla batteries.
Technological breakthrough through clay business
A revolutionary breakthrough in the development of Tesla battery design will likely be brought to the attention of Tesla Inc. from Maxwell Technologies in San Diego. The Maxwell company is developing supercapacitors (ionisters) and is actively researching the technology of solid-state (dry) electrodes. According to Maxwell’s application, using the same technology, an energy capacity of 300 Wh/kg has already been achieved on battery prototypes. The target for Mayday is a breakthrough in energy intensity of over 500 W per year/kg. In addition, the compatibilty of solid-state batteries is 10-20% lower, compared to the rare electrolyte tested by Tesla. The Californian company also announced another bonus - a predicted increase in battery life. In this way, Tesla will be able to achieve the promised 400-mile (643.6 km) range of its electric vehicles and achieve greater competitiveness with comparable cars at a price. 
The new supercar Tesla Roadster 2020 can reach the stated range of 640 km only with completely new batteries.
Has Tesla planned to replace the battery?The German website of the magazine Auto motor und sport reports a little bit about Tesla's ignition of the exhaustion of batteries. All battery cells (components) were supplied to Californians from the Japanese Panasonic manufacturer - for Model S and Model X they are imported directly from Japan, and for Model 3 the batteries are manufactured at Gigafactory 1 in the American state of Nevada a. The production at Gigafactory 1 is managed entirely by Panasonic and Tesla. However, this ultimately led to significant discord, with Panasonic apparently disappointed by Tesla's sales figures, and also fearing that Californians would not expand battery production in the future.
The intrigue behind the launch of the compact Tesla Model Y in 2020 was the increasing availability of batteries
The rhythmic supply of batteries for the Model Y announced in the fall of 2020 has been raised under doubt by Panasonic CEO Kazuhiro Tsuga. At this time, Panasonic has already completed its investment in Gigafactory 1. It is possible that Tesla would like to become independent from the Japanese in the development of the moisture production of battery cells.
Tesla is currently the industry leader in high-capacity battery technology for electric vehicles, and the Californian is aiming to maintain a competitive edge on this principle. The final outcome may be the purchase of Maxwell Technologies, but it remains to be seen how far the San Diego technologists have actually been able to push ahead with the introduction of revolutionary solid-state battery technology to the market. 
If the revolutionary technology of solid-state batteries actually comes to fruition, it is possible that the Tesla Semi electric tractor will become a bestseller on the private market, like the Model 3 on the passenger car market.
For now, many car manufacturers are focusing on the production of battery cells. It seems that Tesla wants to become more independent from its boss Panasonic and therefore also conduct surveillance on its problems.
With the availability of a sufficient number of revolutionary high-energy solid-state batteries, Tesla is gaining a decisive advantage in the market and, having decided to release the long-promised Vlasnik Elon Musk, are really cheap and “long-range electric” volumes, which is due to the avalanche-like growth of the BEV market.
According to CNBC, Tesla's secret laboratory is located near the Tesla plant near Fremont (photo behind the splash screen). Previously, there were notifications about the closed “laboratory zone”, which was in a different version of the enterprise. Of course, this new battery device is the attacker of that big laboratory, and there are even more secrets. 
Tesla's new breakthrough in the automotive market can only be achieved if its line of models becomes even more “long-range” at a significantly reduced price
According to IHS Markit analysts – the most expensive element of a modern electric vehicle – rechargeable battery It’s not Tesla, but Panasonic that takes most of the money for them.
Insiders are not yet able to reveal the real achievements of Tesla's secret laboratory. It is expected that Elon Musk will share his final thoughts at the time of the traditional conference call with investors.
It was previously reported that Tesla plans to sell 1,000 Tesla Model 3 electric cars per unit. Tesla's historic monthly record with the delivery of Model 3 includes 90,700 electric vehicles. If the company is able to deliver the planned number of electric vehicles, this record may be broken.
We often looked at the battery configuration Tesla Model S Capacity 85 kW*year. Apparently, the main element of the battery is a lithium-ion rechargeable battery from the company Panasonic, 3400 mAh, 3.7 V.
Panasonic speaker, size 18650
A typical center is shown for the baby. In fact, Tesla's cores are heavily modified.
Dani seredki in parallel join in groupies 74 pcs.. When connected in parallel, the voltage of the group is equal to the voltage of the skin elements (4.2), and the capacity of the group is equal to the sum of the capacities of the elements (250 Ah).
Dali six groups get together sequentially to the module. In this case, the voltage of the module is calculated from the voltage group and reaches approximately 25 (4.2 * 6 groups). Capacity is lost 250 Ah. Zreshta, modules are connected in series to the battery. This battery contains 16 modules (96 groups in total). The voltage of all modules is calculated and the result is 400 V (16 modules * 25 V).
This battery is supported by an asynchronous electric drive with a maximum power of 310 kW. Shards P=U*I, in nominal mode at a voltage of 400 V, a flow of I=P/U=310000/400=775 A flows through the lancus. At first glance, you might think that this is a divine flow for such a “battery”. Prote, please forget that in parallel connection with Kirchhoff’s first law I=I1+I2+…In, where n is the number of parallel legs. Raz n=74. The fragments in the middle of the group are the internal supports of the middle and we are respectfully mentally equal, then the streams will be the same. Obviously, a stream flows through the middle In=I/n=775/74=10.5 A.
Chi rich or not enough? Good or bad? To ensure that the power supply corresponds to the discharge characteristics of the lithium-ion battery. American folk craftsmen, having removed the battery, carried out a low test. Zokrema, the voltage oscillograms were applied to the baby during a discharge in the middle, taken from a real one Tesla Model S, Strumami: 1A, 3A, 10A.
Splash on the curve 10 A for manual re-mixing navantazhenya at 3A. The author of the experiment carried out another task in parallel, so we won’t dwell on this one.
As you can see from the little one, the discharge of the 10 A strum is completely satisfactory in terms of the voltage of the chamber. This mode corresponds to a 3C curve discharge. It should be noted that we have taken the most critical drop, if the engine tension is maximum. In reality, due to the high-quality dual-motor drive with an optimal gear ratio, the car operates with a discharge of 2...4 A (1C). Even during very sharp acceleration, when driving uphill at high speed, the average can reach 12 ... 14 A.
What advantages does it give? For this purpose, you can choose 2 mm square for the copper conductor crossbar. Tesla Motors kills two birds with one stone here. All connecting guides perform another function of patrons. Obviously, there is no need to vikorist the road system of protection, in addition to vikorist the melting pots. The connecting conductors themselves melt and run into an emergency situation when they are overloaded with a small cut. They wrote a report about them.
For the little ones, the conductors 507 and the same connections.
Come on, let’s take a look at the rest of the food that extols the mind of the present, and the super-cheek cries out. Why does Tesla choose lithium-ion batteries?
I will immediately say that from whose food I will express my subjective thoughts. You can't get along with him)
We will carry out a thorough analysis different types batteries
Obviously, the lithium-ion battery lasts for today's most popular pets. The best batteries for the intensity of energy and mass/size ratios, unfortunately, the mass production does not understand. That's why Tesla It was decided to create such a balanced battery that it would provide a range of up to 500 km.
Another reason, in my opinion, is marketing. On average, the service life of such energizers is approximately 500 charge-discharge cycles. This means that if the car is active, you will have to replace the battery after a maximum of two years. I want the company to work effectively.
Traction lithium-ion batteriesTesla, what's in the middle?
Tesla Motors is the creator of truly revolutionary electric vehicles - electric vehicles that are not only mass-produced, but also have unique models that allow them to be produced literally every day. Today we will take a look at the traction battery of the Tesla Model S electric car, we will see how it is inspired by the magic of success of this battery.
Batteries are supplied to clients in such axle boxes made of OSB.
The largest and most expensive spare part for the Tesla Model S is the traction battery unit.
The traction battery unit is located in the bottom of the car (essentially a substitute for an electric car), which is why the Tesla Model S has a very low center of the car and a miraculous ceramic coating. The battery is attached to the power part of the body using tight brackets (div. photo below) and plays the role of the power part of the car body.
According to data from the American Environmental Protection Agency (EPA), one charge of a Tesla traction lithium-ion battery with a nominal voltage of 400 V DC, with a capacity of 85 kW per year, lasts for 265 miles (426 km) gu, which allows such electric vehicles. From 0 to 100 km/year, such a car accelerates in just 4.4 seconds.
The secret to the success of the Tesla Model S is its highly efficient cylindrical lithium-ion batteries with high energy capacity, the source of the basic elements is from the Japanese company Panasonic. It was a little chilly to walk around the batteries.
Aboutdin zthem – tsedon't interfere, kill me!
One of the Tesla Model S enthusiasts and enthusiasts from the United States is planning to replace the battery for the Tesla Model S with an energy capacity of 85 kW per year in order to study its design in detail. Before speaking, the cost of spare parts in the USA is 12,000 USD.
On top of the battery block there is a heat and soundproofing coating, which is covered with thick polyethylene film. It is known to be covered, it looks like a kilim and is prepared before disassembling. To work with a battery, you need to insulate the tool and scrub it with gum and dry gum gloves.
Tesla battery. Let's figure it out!
The Tesla traction battery (traction battery unit) consists of 16 battery modules with a nominal voltage of 25V (battery unit rating is IP56). Sixteen battery modules are connected in series to a battery with a nominal voltage of 400V. The battery module consists of 444 elements (batteries) 18650 Panasonic (the capacity of one battery is 46 g), which are connected to a 6s74p circuit (6 elements in succession and 74 such groups in parallel). The total number of Tesla traction batteries is 7104 such elements (accumulators). The battery is protected from the extra core behind a metal casing with an aluminum cover. On the inside of the glazed aluminum cover there are plastic linings that look like spitting. The aluminum cover is secured with screws with metal and gum gaskets, which are sealed with additional silicone sealant. The traction battery unit is divided into 14 cells, a battery module is located in each cell. Sheets of pressed mica are placed on the skin of the animal and on the bottom of the battery modules. Mica sheets provide good electrical and thermal insulation of the battery to the electric vehicle body. Next to the front of the battery under its cover there are two similar battery modules. The skin has 16 battery modules and includes a BMU unit that connects to under the legal system The BMS, which operates robotically, follows the parameters and also ensures the protection of all batteries. The lead terminals (terminal) are located at the rear of the traction battery unit.
Before I turned it on, there was a very low electrical voltage (around 313.8V), so to speak about the fact that the battery was discharged and was not in operation.
Battery modules rely on the high density of Panasonic 18650 cells (batteries), where the parts are placed and the precision of the parts. The entire assembly process at the Tesla factory takes place in a completely sterile environment, with robots being used, subject to varying temperatures and humidity.
The battery module consists of 444 elements (batteries), which look very similar to simple AA batteries - all 18650 lithium-ion cylindrical batteries manufactured by Panasonic. The energy capacity of the skin battery module of such elements is 5.3 kWh.
In Panasonic 18650 batteries, the positive electrode is graphite, and the negative electrode is nickel, cobalt and aluminum oxide.
The Tesla traction battery weighs 540 kg, and its dimensions are 210 cm in the back, 150 cm in the back, and 15 cm in the back. The amount of energy (5.3 kW year) that is generated by just one unit (with 16 battery modules) is equal to the amount that is generated by hundreds of batteries in 100 laptop computers. To the minus of the skin element (battery), as a connection, a tension rod (external struma interconnector) is soldered, which in case of translocation of the struma (or when short circuit) burns and contaminates the lance, in which case only the group (with 6 batteries) is not processed into any element, all other batteries continue to be processed.
The Tesla traction battery is cooled and heated by an additional system based on antifreeze.
When collecting its batteries, Tesla collects elements (batteries) manufactured by Panasonic in various countries, such as India, China and Mexico. Final testing and placement in the battery case is being carried out in the United States. Tesla provides a service warranty for its products (including the battery) for up to 8 years.
In the photo (light up) the elements are Panasonic 18650 batteries (the elements are rolled on the side plus “+”).
Thus, we found out what makes up the Tesla Model S rechargeable traction battery.
Thank you for your respect!
