Description
Technical Field

Background
There are slight differences with the types of new energy automobiles. In a pure new energy vehicle equipped with only a battery, the battery serves as the sole source of power for the vehicle drive system. In a hybrid vehicle equipped with a conventional engine (or fuel cell) and a battery, the battery may serve as both a primary power source and an auxiliary power source for the vehicle drive system. It can be seen that at low speed and start-up, the battery plays the role of the main power source of the automobile driving system; during full-load acceleration, the auxiliary power source acts; during normal driving, deceleration and braking, the energy storage role is played.
Currently, new energy automobile batteries can be divided into two main types, namely storage batteries and fuel cells. The storage battery is suitable for pure new energy automobiles, and can be classified into lead-acid storage batteries, nickel-based batteries (nickel-hydrogen and nickel-metal hydride batteries, nickel-Fu and nickel-zinc batteries), sodium beta batteries (sodium-sulfur batteries and sodium-nickel chloride batteries), secondary lithium batteries, air batteries and the like. The fuel cell is specially used for new energy automobiles, and can be classified into Alkaline Fuel Cells (AFC), phosphoric Acid Fuel Cells (PAFC), molten Carbonate Fuel Cells (MCFC), solid Oxide Fuel Cells (SOFC), proton Exchange Membrane Fuel Cells (PEMFC), direct Methanol Fuel Cells (DMFC), and the like.
In the prior art, as the storage battery can emit a large amount of heat during working, if the heat in the battery is not emitted timely, the battery can burn, even explosion and the like can occur, and the driving safety is easily affected. Therefore, the battery needs to be managed to avoid accidents.
