Graphical 800V power battery system of Aston Martin electric supercar

Lithium Grid News: In the segment of electric sports cars, Ferrari, Porsche, Mercedes-Benz, and Audi are all doing it. This is a bit tangled. Aston Martin’s current Rapid E u200bu200bbattery solution is similar to the original There is a pure electric supercar that has been modified under the supercar system.

From the appearance of this picture, the battery passes through the central channel and there is a front space.

From the picture below, the power battery system (800V 65kWh) is very concentrated. The above picture and the bottom picture are a bit different in structure, but it may be that half of the battery is placed in the front of the car, the middle is connected, and the other half is placed in the back.

Rapide E will be powered by an 800V battery electrical architecture with a 65 kWh pack comprising more than 5600 18650 format Li-ion cylindrical cells.

Batteries The system is placed on the head and arranged according to the position of the original engine

Back to this matter, let’s talk about something interesting. Aston Martin was unable to develop the battery pack from scratch on its own. The shape and form of the development of this special-shaped battery system is still unknown. It came with Williams Advanced Engineering. This company acquired the British ZF funding.

On the one hand, in F1 The power battery system is developed inside, and the power battery system is also developed for Land Rover.

Strange things

Samsung SDI will provide cylindrical batteries for electric vehicles (EVs) under Jaguar Land Rover. South Korean battery manufacturer Samsung will build a production line for producing '21700' cylindrical lithium batteries in a battery plant in Hungary. Jaguar Land Rover plans to install 21700 lithium batteries on next-generation electric vehicles and put them on the market in 2020. It is expected that in the early stage, Samsung SDI will provide 5 gigawatt-hours (GWh) of electric vehicle batteries each year, that is, approximately 300 million cylindrical cells. Switching from a soft bag to a cylinder, how to get it and what purpose it is, you need to dig a little more carefully.

Summary: For the development of new energy vehicles in the UK, it started with Jaguar’s Ipace. With high-end and ultra-high-end electric sports cars, it seems that soft cases and cylinders are used more. In the process of data, I saw a very interesting explanation of Williams Advanced Engineering, the energy density loss from battery cell to pack.
