The invention discloses a charging fault processing method for an electronic control unit of an electric vehicle and the electronic control unit, and the method comprises the steps: responding to a charging fault, stopping charging, and determining whether the charging fault is a recoverable fault; if the charging fault is a recoverable fault, dormancy information is sent to other electronic control units except the electronic control unit of the electric vehicle, the electronic control units enter a pseudo dormancy state, the other electronic control units enter dormancy after receiving the dormancy information, in the pseudo dormancy state, the electronic control unit does not enter dormancy, and in the pseudo dormancy state, the electronic control unit does not enter dormancy; and detecting whether the charging fault is recovered, if the charging fault is detected to be recovered, awakening other electronic control units, and recovering charging. When a recoverable charging fault occurs in vehicle charging, the electronic controller serving as a fault recovery detection controller does not sleep, other ECUs of the vehicle enter sleep, it can be guaranteed that the quiescent current of the whole vehicle is small, feeding of a small storage battery is not caused, and charging can be continued after a charging fault source is recovered.

    本发明公开一种电动汽车的电子控制单元充电故障处理方法及电子控制单元,方法包括:响应于充电故障,停止充电,并确定充电故障是否为可恢复故障;如果充电故障为可恢复故障,则向电动汽车除本电子控制单元以外的其他电子控制单元发出休眠信息,并进入伪休眠状态,其他电子控制单元在接收到休眠信息后进入休眠,在伪休眠状态下,本电子控制单元不进入休眠,检测充电故障是否恢复,如果检测到充电故障恢复,则唤醒其他电子控制单元,并恢复充电。本发明在车辆充电出现可恢复充电故障时,除作为故障恢复检测控制器的电子控制器不休眠外,车辆其他ECU进入休眠,既能保证整车静态电流小,不会导致小电瓶馈电,而且当充电故障源恢复后能恢复继续充电。
