There have been too many cases of spontaneous combustion of new energy pure electric vehicles in China before, and many consumers have questioned new energy vehicles for a while. How to evaluate the battery safety of new energy vehicles? The battery of an energy vehicle is a complex system, which can be simply understood in three levels: 1. Cell: positive electrode material, negative electrode material, and electrolyte form the cell. 2. Battery pack: hundreds to thousands of cells are combined to form a battery pack, commonly known as Pack. 3. System: Add sensors (eyes and ears) to measure voltage, current, and temperature; use BMS (brain) to meditate and make decisions; add actuators (hands and feet) to control switches, and it becomes a system. Naturally, the safety of new energy vehicle battery systems can also be understood from the three levels of battery cells, battery packs, and systems.
