The invention discloses a power domain controller of an electric vehicle. According to the power domain controller, seven controllers including a whole vehicle controller, a charging control unit, a motor controller, a main control board of a battery management unit, a vehicle-mounted charger controller, a direct current conversion controller and a vehicle pile interconnection controller are integrated. According to the invention, the seven controllers, namely, the whole vehicle controller, the charging control unit, the motor controller, the main control board of the battery management unit, the vehicle-mounted charger controller, the direct current conversion controller and the vehicle pile interconnection module, are arranged in the same power domain controller, so that the reuse rate of components is improved, the hard wire connection is reduced, the arrangement bracket of each controller is saved, and the cost is reduced. The size of the whole vehicle is reduced, and the weight is reduced, so that the space and the weight are greatly saved; communication signal interaction among original controllers is reduced, the load rate of a communication network is reduced, and it is ensured that communication of the whole vehicle is more stable and reliable.
本发明公开了一种电动汽车动力域控制器。该动力域控制器包括:将整车控制器、充电控制单元、电机控制器、电池管理单元的主控板、车载充电机控制器、直流转换控制器、车桩互联控制器七种控制器进行了整合。本发明通过将整车控制器、充电控制单元、电机控制器、电池管理单元的主控板、车载充电机控制器、直流转换控制器、车桩互联模块这七种控制器于同一个动力域控制器中,提高了元器件的复用率,减少了硬线连接,节省了各控制器布置支架,使得整车体积变小、重量减轻,从而大幅节省了空间和重量;减少了原各个控制器之间的通信信号交互,降低了通信网络的负载率,确保整车的通信更加稳定可靠。
