The invention discloses a charging control method for a vehicle control unit of an electric vehicle and the vehicle control unit, and the method comprises the steps: receiving a to-be-charged state message sent by a vehicle-mounted charger, and enabling the vehicle-mounted charger to be directly connected with a power battery system of the electric vehicle; the motor is prohibited from running, and the vehicle is controlled to park; when the parking of the vehicle is completed, a self-checking command is sent to a high-voltage part of the vehicle; if all the high-voltage components of the vehicle are self-checked normally, charging parameters are obtained from the battery management system, the charging parameters are sent to the vehicle-mounted charger, and the vehicle-mounted charger is controlled to start charging the power battery system; and in response to the charging stop event, controlling the vehicle-mounted charger to stop charging the power battery system. A charging system architecture of a power battery system (PACK) without an alternating current relay is redesigned, a vehicle control unit (VCU) serves as a host, other multiple controllers serve as slaves, the VCU is controlled in the charging process, and tight communication, joint debugging and actions are achieved.

    本发明公开电动汽车整车控制器充电控制方法及整车控制器,方法包括:接收到车载充电机发送的待充电状态报文,车载充电机与电动汽车的动力电池系统直连;禁止电机运行,并控制车辆驻车;当接收到车辆驻车完成时,向车辆高压部件发出自检命令;如果车辆所有的高压部件自检正常,则从电池管理系统获取充电参数,将充电参数发送至车载充电机,并控制车载充电机开始向动力电池系统充电;响应于充电停止事件,控制车载充电机停止向动力电池系统充电。本发明对动力电池系统(PACK)去掉交流继电器的充电系统架构重新设计,将整车控制器VCU作为“主机”,其他多个控制器作为“从机”,充电过程中接受VCU控制,实现紧密通讯、联调和动作。
