The invention provides a control method suitable for preheating of a power battery of a direct-current fast charging pile. The method comprises the steps: whether charging handshake identification work of the direct-current quick charging pile and the electric vehicle is completed or not is determined; if the handshaking work is completed, the electric vehicle sends a message that the vehicle is not ready to the direct-current quick charging pile, and whether the power battery needs to be heated or not is determined; if soothe heating is required, the power battery adds battery pure heating preparation to a message that a vehicle is ready sent to the direct-current fast charging pile, and the direct-current fast charging pile heats the power battery, after heating is completed, the electric vehicle sends a message that the vehicle is ready to the direct-current fast charging pile; in addition, under the condition that it is determined that heating is unnecessary, the electric vehicle sends a message that the vehicle is ready to the direct-current fast charging pile; and the direct-current quick charging pile charges the power battery after receiving a message that the electric vehicle is ready from the electric vehicle. According to the invention, the battery pure heating function can be realized in the direct-current quick charging pile, and the front-back compatibility and inheritance are better.
本发明提供适用于直流快充桩的动力电池预加热的控制方法。该方法包括:判断直流快充桩与电动车的充电握手辨识工作是否完成;在握手工作完成后,电动车向直流快充桩发送车辆未准备就绪的报文,并判断动力电池是否需要加热;在判断为需要加热的情况下,动力电池在向直流快充桩发送的车辆准备就绪的报文中加入电池纯加热准备完成,直流快充桩对动力电池加热,加热完成后,电动车向直流快充桩发送车辆准备就绪的报文,另外在判断为不需要加热的情况下,电动车向直流快充桩发送车辆准备就绪的报文;直流快充桩从电动车收到车辆准备就绪的报文后,对动力电池充电。根据本发明,能够在直流快充桩实现电池纯加热功能,并且前后兼容性和继承性较好。
