The invention provides a method for reserving direct current charging, which is applied to a whole vehicle end and comprises the following steps: establishing connection between the whole vehicle end and an external charging device; the man-machine interaction equipment of the whole vehicle end receives input information; the vehicle control unit identifies the input information and confirms whether reserved charging needs to be carried out or not: if the reserved charging needs to be carried out, a first BRM message is formed according to a confirmation result, and the first BRM message is sent through a CAN bus; the method comprises the following steps: receiving an external wake-up signal, receiving external message information, and judging whether reserved charging can be executed according to the external message information: if so, entering a first reserved charging mode, and before the external wake-up signal is received, the whole vehicle end is in a dormant state, and when the external wake-up signal is received, the whole vehicle controller is awakened and performs direct current charging; if not, carrying out direct current charging; and if the reserved charging is not needed, forming a second BRM message according to a confirmation result, and sending the second BRM message through the CAN bus, so that the whole vehicle end performs direct current charging.
本发明提供了一种预约直流充电的方法，应用于整车端，包括：整车端与一外部充电装置建立连接；整车端的人机交互设备接受一输入信息；整车控制器对输入信息进行识别，确认是否需要进行预约充电：若需要预约充电，则根据确认的结果形成第一BRM报文，将所述第一BRM报文通过CAN总线发送；并接收外部报文信息，根据所述外部报文信息判断是否可以执行预约充电：若是，则进入第一预约充电模式，且在接收到外部唤醒信号之前，所述整车端处于休眠状态，在接收到外部唤醒信号时，所述整车控制器被唤醒并进行直流充电；若否，则进行直流充电；若不需要预约充电，则根据确认的结果形成第二BRM报文，并将所述第二BRM报文通过CAN总线发送，所述整车端进行直流充电。
