How a Tesla Model S electric vehicle battery works
Tesla Motors is the creator of truly revolutionary eco-vehicles, which not only are mass-produced, but also have unique indicators that allow their use literally daily.
Today we take a look inside the battery of the Tesla Model S electric car and find out how it works.
According to the North American Environmental Protection Agency (EPA), the Model S needs only one recharge of 85 kWh batteries to cover more than 400 km, which is the most significant indicator among similar vehicles on the specialized market. To accelerate to 100 km / hour, an electric car only needs 4.4 seconds.
The success of this model is the presence of lithium-ion batteries, the main components of which are supplied for Tesla by Panasonic. Tesla batteries are fanned by legends. And so 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 45 000 USD.
The battery is located in the bottom, so Tesla has a low center of gravity and excellent handling. He joins the body through the brackets.
The battery compartment is formed by 16 blocks that are connected in parallel and protected from the environment by means of metal plates, as well as a plastic lining that prevents the ingress of water.
Opening the Tesla Model S battery
Before completely disassembling it, the electrical voltage was measured, confirming the operating status of the battery.
Battery assembly is characterized by high density and precision fitting parts. The whole picking process takes place in a completely sterile room, using robots.
Each unit consists of 74 cells that look extremely similar to simple finger-type batteries (Panasonic lithium-ion cells), divided into 6 groups. At the same time, it is almost impossible to figure out the scheme of their placement and operation - this is a big secret, which means it will be extremely difficult to make a replica of this battery. Chinese analog battery Tesla Model S, we hardly see.

In the role of the positive electrode is graphite, and the negative - nickel, cobalt and aluminum oxide.The specified amount of electrical voltage in the capsule is 3.6V.

The most powerful of the available batteries (its volume is 85 kWh) consists of 7104 of these 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 out of 16 is equal to the amount produced by hundreds of batteries from portable computers.
Tesla battery pack in parsing
When assembling their batteries, Tesla uses elements made in various countries, such as India, China, Mexico, but final improvements and equipment are made in the United States. The company provides warranty service for its products for up to 8 years.
