Focusing on the precise control of the core power and body state of automobiles, the core components include on-board micro control units (MCU), engine control units (ECU), battery management system (BMS) chips, motor control chips, and power devices, etc. Its core function is to complete key processes such as power parameter adjustment, body attitude control, and management of the three-electric system of new energy vehicles. It directly determines the power output efficiency, fuel economy (or power consumption), and driving stability of the vehicle (such as ESP body stability control). It is the core support for ensuring the basic driving functions of the vehicle and the electrification upgrade.
