In electric vehicles, 40% of the cost comes from batteries, which are like the heart that provides "pumping function" for electric vehicles. The performance and lifespan of batteries are important indicators for measuring the performance of electric vehicles. How to master these indicators and ensure that each battery operates optimally? It all relies on the Battery Management System (BMS), which plays the role of a "battery nanny" in the battery operation system. It processes sufficiently rich signals, including battery cells, collisions, CAN, charging, water pumps, high voltage, insulation, and so on.
