How is the battery of the car Tesla Model S

Let's look inside the battery of an electric car Tesla Model S and find out how it is arranged.

According to the North American Environmental Protection Agency (EPA), Model S is enough for a single charge of 85 kWh batteries to cover more than 400 km, which is the most significant indicator among similar cars on the specialized market. For acceleration to 100 km / h, an electric car only needs 4.4 seconds.

The key to the success of this model is the presence of lithium-ion batteries, the main components of which are supplied to Tesla by Panasonic. Tesla batteries are fanned with legends. And so one of the owners of such a battery decided to violate 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 at 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, which are parallel connected and protected from the environment by means of metal plates, as well as a plastic overlay that prevents water from entering.

Before disassembling it completely, an electrical voltage was measured, confirming the working state of the battery.

Battery assembly is characterized by high density and precision fitting parts. The whole assembly process takes place in a completely sterile room, using robots.

Each unit consists of 74 elements, which are very similar in appearance 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 layout of their placement and operation - this is a big secret, which means that making a replica of this battery will be extremely difficult. The Chinese equivalent of the Tesla Model S battery, we are unlikely to see.

Graphite serves as a positive electrode, and nickel, cobalt and alumina serve as a negative electrode. The indicated volume of electrical voltage in the capsule is 3.6V.

The most powerful battery available (its capacity is 85 kWh) consists of 7, 104 such 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 generated by just one block of 16 is equal to the amount produced by a hundred batteries from laptop computers.

When assembling their batteries, Tesla uses elements manufactured in various countries, such as India, China, Mexico, but the final refinement and packaging are made in the United States. The company provides warranty service for its products for up to 8 years.
