The embodiment of the invention discloses a charging method, which is applied to a vehicle control unit of an electric vehicle, and comprises the following steps: when the electric vehicle in an OFF gear is connected with a direct current charging pile and cannot be charged and a battery controller of the electric vehicle is in an awakening state, receiving the state of a battery of the electric vehicle, and when the state of the battery is in a non-fully-charged state, starting the battery controller of the electric vehicle; setting a wake-up demand, performing high-voltage power-on on the electric vehicle, setting a state identifier of the electric vehicle as a first indication value when the high-voltage power-on on the electric vehicle is successfully completed, and sending the state identifier to a battery controller, the first indication value is used for indicating that the electric vehicle is in a chargeable state to enable the battery controller to start a charging action so as to enable the direct-current charging pile to charge the battery. The embodiment of the invention further provides a charging device, a vehicle control unit, a battery controller and an electric vehicle.

    本发明实施例公开了一种充电方法,包括:该方法应用于电动车辆的整车控制器中,当处于OFF档位的电动车辆连接直流充电桩无法充电,且电动车辆的电池控制器处于唤醒状态时,接收电动车辆的电池的状态,当电池的状态处于未充满状态时,置位唤醒需求,对电动车辆进行高压上电,当成功完成对电动车辆的高压上电时,将电动车辆的状态标识置为第一指示值,并将状态标识发送至电池控制器,第一指示值用于指示电动车辆处于可充电状态以使得电池控制器开启充电动作以使得直流充电桩向电池充电。本发明实施例还同时提供了一种充电装置、整车控制器、电池控制器和电动车辆。
