The invention discloses a power domain controller system, which comprises a vehicle control unit and a battery management system, wherein the battery management system comprises a low-voltage microcontroller, and the vehicle control unit is connected with the low-voltage microcontroller and is used for carrying out fault monitoring on the low-voltage microcontroller; and after the fault is removed, the low-voltage microcontroller generates a fault removal signal and sends the fault removal signal to the vehicle control unit. Core functions of the vehicle control unit, the battery management system and the motor controller are integrated into a power domain control system, the crossing of the power system controller from three traditional controllers to one single controller is realized, the hardware cost of the power system controller is effectively reduced, and the problems of numerous controllers and complex whole control system in the existing electric automobile are solved.
本发明公开了一种动力域控制器系统,包括整车控制器和电池管理系统,所述电池管理系统包括低压微控制器,所述整车控制器与低压微控制器连接,对低压微控制器进行故障监测;所述低压微控制器在故障解除后,发生故障排除信号给所述整车控制器。通过将整车控制器、电池管理系统、电机控制器的核心功能集成到一个动力域控制系统中,实现了动力系统控制器由传统的三个控制器向单独一个控制器的跨越,有效降低动力系统控制器硬件的成本,解决了目前电动汽车中控制器繁多、整个控制系统复杂的问题。
