Xiaomi Motors applies for patent for new technology that can significantly improve battery charging efficiency

Xiaomi Automotive Technology Co., Ltd.’s patent for “a silicon-carbon porous anode material and its preparation method and application” was published. The power battery in this embodiment of the utility model is provided with liquid cooling plates on both sides of each row of cells, so that each row of cells can be cooled by two liquid cooling plates, resulting in a large cooling area, which greatly improves the cooling efficiency. , improving the battery life, safety performance and fast charging performance.

The patent summary shows that the power battery includes: multiple rows of battery cells, multiple liquid cooling plates, a liquid inlet component and a liquid outlet component. Liquid cooling plates are attached to both sides of each row of battery cells, and the liquid cooling plate has a liquid inlet. , liquid outlet and an internal channel connecting the liquid inlet and liquid outlet; the liquid inlet assembly is connected to each liquid inlet and is used to transport coolant into the liquid cooling plate; the liquid outlet assembly is connected to each liquid outlet, Used to receive the coolant discharged from the liquid cooling plate.

Simply put, this patent improves the charging speed of the battery while ensuring its service life and safety. In the current new energy vehicle market, range anxiety is still one of the biggest reasons why people resist electric vehicles. Problems such as being unable to run long distances, not being able to find a charging station , charging too slowly, and battery life being too short are the concerns of most people. If the above problems can be effectively solved, the popularity of new energy vehicles will be greatly increased.

Xiaomi Automotive Technology Company has frequently announced patented technologies recently. For example, in early December this year, Xiaomi Automobile Technology Co., Ltd. announced a patent for "a silicon-carbon porous anode material and its preparation method and application." It is reported that the material prepared publicly has good electronic conductivity and can improve the energy density and cycle performance of power batteries.

In addition, in September this year, the patent "Charging equipment, methods, devices, vehicles, electronic equipment and storage media" applied by Xiaomi Auto Technology Co., Ltd. was authorized. This patent can realize fast charging of vehicles and high-voltage platform charging of vehicles, improving It improves the intelligence and convenience of charging.
