Tesla battery model s. How Tesla Model S. car battery is arranged. The use of lithium-ion battery elements
We partially reviewed the configuration of the battery. Tesla Model S. Capacity 85 kW * h. Recall, the main element of the battery is the lithium-ion rechargeable cell of the company Panasonic, 3400 Mah, 3.7 V.
Panasonic cell, sizes 18650
The figure shows a typical cell. Really, the cells are slightly modified in the Cell.
Cell data parallel Connect B. groups of 74 pcs. With a parallel connection, the group voltage is equal to the voltage of each of the elements (4.2 V), and the group capacity is equal to the amount of the containers of the elements (250 Ah).
Further six groups Connect sequentially in the module. In this case, the voltage of the module is summed from the voltages of groups and is approximately 25 V (4.2 V * 6 groups). Capacity remains 250 Ah. Finally, modules are connected sequentially into the battery.. Total battery contains 16 modules (total 96 groups). The voltage of all modules at the same time is summed up and amounts to 400 V (16 modules * 25 V).
As a load for this battery, asynchronous electric drive is a maximum power of 310 kW. Since P \u003d U * i, in the nominal mode at a voltage of 400 V in the circuit flows the current I \u003d P / U \u003d 310000/400 \u003d 775 A. At first glance it may seem that it is a crazy current for such a "battery". However, you should not forget that with a parallel compound according to the first law of Kirchhoff I \u003d I1 + I2 + ... In, where n is the number of parallel branches. In our case, n \u003d 74. Since inside the group internal resistance of the cells, we consider it conventionally equal, then the currents in them will be the same.Accordingly, current directly through the cell flows In \u003d i / n \u003d 775/74 \u003d 10.5 A.
Is there a lot or a little? Good or bad? In order to answer these questions, refer to the discharge characteristic of the lithium-ion battery. American folk craftsmen, disassembled the battery, conducted a series of tests. In particular, the figure shows voltage oscillograms when the cell discharges taken from the real Tesla Model S., currents: 1a, 3a, 10a.
Splash on curve 10 A due to manual load switching on 3a. The author of the experiment solved in parallel another task, we will not stop on it.
As can be seen from the figure, the discharge of a current of 10 A fully satisfies the requirements for the voltage of the cell. This mode corresponds to the category of curve 3C. It should be noted that we took the most critical case when the engine power is maximum. Really, taking into account the very use of a two-dimensional drive with an optimal gear ratio of gearboxes, the car will work with a discharge 2 ... 4 A (1C). Only at the moments of very sharp acceleration, when driving up a mountain at high speed, cell current can reach in a peak of 12 ... 14 A.
What other benefits does it give? For this load in the case of direct current, the cross section of the copper conductor can be chosen 2 mm.kv. Tesla Motors. Kills two hares here. All connecting conductors also perform the fuse function. Accordingly, there is no need to use an expensive protection system, additionally use fuses. The connecting conductors themselves in the case of current overload due to the small section melted and prevent an emergency. We wrote more about this.
In the picture, the conductors 507 are the most connectors.
Finally, consider the last question, who worrying the minds of modernity, and causing a wave of disputes. Why does Lithium-ion batteries use Tesla?
Immediately make a reservation, that specifically in this matter I will express my own, subjective opinion. You can not agree with him)
We carry out a comparative analysis of different types of batteries.
Obviously, the lithium-ion battery has the highest specific indicators today. The best battery over the energy density and the ratio of mass / dimensions is still no alas, there is no mass production. That is why B. Tesle. It turned out to make such a balanced battery, providing a stroke of up to 500 km.
The second reason, in my opinion, marketing. All the same, on average, the resource of such cells is about 500 cycles charge-discharge. And this means that with the active use of the car, you will have to replace the maximum battery in two years. Although the company is really.
The new generation of Tesla batteries is designed in the secret zone
Alexander Klimnov, photo Tesla and Teslarati.com
Today Tesla Inc. It works very hard on the next generation of already its own batteries. They must keep a much greater amount of energy and at the same time become much cheaper.
New rechargeable batteries can begin to apply on a promising TESLA pickup (drawing of a possible pickup picap, which for other data can become more brutal, as it will have to be able to see the current bestseller of America Ford F-Series from the market)
Californians were those who created the first electric vehicles suitable for serial production. Energy-intensive lithium-ion batteries, thus, radically adjusted their stroke reserve. At that time, the batteries model Roadster - Tesla's primary brand, consisted of thousands of ordinary finger batteries for laptops, now for electric vehicles lithium-ion batteries are created specifically. Now they produce many manufacturers, but the advanced TESLA technology still allows it to remain the leader in the energy-intensive battery segment. However, the world's first information on the following even more powerful generation of Tesla batteries began to leak into the world media.
Technological breakthrough through business absorption
The revolutionary jump, in terms of the development of the design of Tesla batteries, will probably be due to the acquisition of Tesla Inc. Maxwell Technologies from San Diego. Maxwell manufactures supercapacitors (Ionister) and actively explores the technology of solid-state (dry) electrodes. According to Maxwell, when using this technology, it has already achieved energy intensity at the level of 300 watts of the battery. The task for the future is a breakthrough to the level of energy intensity of more than 500 W h / kg. In addition, the cost of producing solid-state batteries should be 10-20% lower than those used by today Tesla with a liquid electrolyte. The California company also reported another bonus - predicted doubling battery life. Thus, Tesla will be able to reach the coveted 400-mile (643.6 km) mileage of its electric vehicles and achieve complete competitiveness with ordinary cars for the price. 
The new Tesla Roadster Supercar 2020 will be able to reach the stated stroke stock of 640 km only on fundamentally new batteries.
Tesla planned the own production of AKB?The German website of the AUTO Motor und Sport magazine informs about stubborn rumors about the deployment of Tesla's own production of batteries. Until now, the rechargeable elements (cells) of Californians supplied the Japanese Panasonic manufacturer - for Model S and Model X, they are imported directly from Japan, and for Model 3 cells are produced at Gigafactory 1 in the US state of Nevada. Production on Gigafactory 1 jointly manage Panasonic and Tesla. However, recently it led to huge disagreements, as Panasonic was obviously disappointed with Tesla sales rates, and also feared that Californians would not expand this production of batteries in the future.
Input Startup Compact Tesla Model Y In 2020, the source of batteries arrived
In particular, the rhythmic supply of batteries for an announced on autumn 2020 Model Y is questioned by the Director General of Panasonic Casukhiro Tsuga. Currently, Panasonic at all ceased its investment in Gigafactory 1. Perhaps Tesla wants to become independent of the Japanese by mastering their own production of battery elements.
Tesla today acts as a leader in high-tank batteries for electric vehicles and Californians firmly intend to defend its fundamental competitive advantage. The crucial step can be the purchase of Maxwell Technologies, but it depends on how much San Diego experts really managed to advance to the conclusion of the revolutionary technology of solid-state batteries. 
If the revolutionary technology of solid-state batteries really take place, it is possible that Tesla SEMI electric shock will become a bestseller in the cargo market, like Model 3 on the passenger
So far, many automakers are configured on their own production of battery elements. It seems that Tesla wants to become more independent of its supplier Panasonic and therefore also conducts research in this area.
With the advent of the revolutionary high-energy solid-state batteries, Tesla will receive a decisive advantage in the market and, finally, releases a long-promised Ilona mask owner, really cheap and "long-range" electric cars, which will cause an avalanche growth of the BEV market.
According to CNBC sources, the secret TESLA laboratory is located in a separate building near the Tesla plant in Frimont (photo by the screensaver). Previously, there were messages about the closed "zone-laboratory", which was on the second floor of the enterprise. Probably, the current rechargeable division is the successor of the former laboratory, but even more classified. 
A valid breakthrough in the Tesla automotive market will be able to achieve only if its line of models will become even more "long-range" with a significant price reduction
According to analysts IHS Markit, the most expensive element of the modern electric vehicle is a battery, but most of the money receives not Tesla, but Panasonic.
Insiders are not yet able to report the real achievements of the secret laboratory TESLA. It is assumed that Ilon Mask will share it at the end of the year during the traditional conference session with investors.
Earlier it was reported that Tesla plans to sell 1000 electric vehicles Tesla Model 3 per day. The current monthly record TESLA for the supply of Model 3 is 90,700 electric vehicles. If companies manage to put a planned amount of electric vehicles in June, this record can be broken.
We will look inside the electric vehicle battery Tesla Model S and find out how it is arranged.
According to the North American Environmental Protection Agency (ELE), Model S is enough one post-85 kW batteries for overcoming more than 400 km, which is the most significant indicator among such cars presented in the specialized market. For overclocking up to 100 km / hour, only 4.4 seconds are enough to the electrocaria.
The key to the success of this model is the presence of lithium-ion batteries, the main components of which are shipped for Tesla by Panasonic. Tesla Batteries are sheaven legends. And therefore one of the owners of such a battery decided to break its integrity and find out what it is inside. By the way, the cost of such a battery is equal to 45 000 USD.
The battery is located in the bottom, thanks to which Tesla has a low center of gravity and excellent handling. He joins the body through brackets.
We disassemble:
The battery compartment is formed by 16 blocks that are parallel to and are fencing from the environment by means of metal plates, as well as a plastic overlay that prevents water from entering.
Before it fully disassembled, the electrical voltage was measured, confirmed the working condition of the battery.
The accumulation of batteries is distinguished by high density and precision fitting parts. The entire configuration process passes in a completely sterile room using robots.
Each block consists of 74 elements, it looks extremely similar to simple palter batteries (Panasonic lithium-ion cells) divided into 6 groups. At the same time, find out the scheme of their placement and work is almost unrealistic - this is a big secret, which means that the replica of this battery will be extremely difficult. Chinese Analog Battery Tesla Model S We are unlikely to see.
The role of a positive electrode is graphite, and negative - nickel, cobalt and aluminum oxide. The specified amount of electrical voltage in the capsule is 3.6V.
The most powerful of the existing batteries (its volume is 85 kW * h) consists of 7104 similar batteries. And it weighs about 540 kg, and its parameters are 210 cm in length, 150 cm in width and 15 cm in thickness. The amount of energy produced by just one block of 16 is equal to the number produced by hundreds of batteries from laptop computers.
When assembling its tesla batteries, elements manufactured in various countries, such as India, PRC, Mexico, but final refinement and equipment are made in the United States. The company provides warranty service for its products for up to 8 years.

So you learned from which the Tesla Model S Battery and the principle of its work. Thank you for your attention.
To understand, I will explain, this battery pack consists of several thousand most common and very common lithium ionic batteries of type 18650. These IPs are great for powerful lanterns, or to reserve charges of gadgets through a special adapter. And if someone does not know lithium ion batteries in case of damage inclined in self-ignition and explosions, a fire post from Tesla blowing up in Los Angeles because of the battery raised during the chase, it will be visible on the harves.
