The invention provides an electric vehicle and a charging method applied to the electric vehicle, the electric vehicle comprises a power battery, a load, a charging socket and a controller, one end of the charging socket is connected with the power battery and the load through a high-voltage positive and negative direct current bus, and the other end of the charging socket is used for being connected with a charging gun of a power supply device. Under the condition that the charging socket is connected with the charging gun, the controller is used for controlling the power battery to switch on a loop for supplying power to the X capacitor connected in parallel at two ends of the power battery; in response to the fact that the voltage at the two ends of the X capacitor reaches a preset value, the controller is used for controlling the loop for the power battery to supply power to the X capacitor to be disconnected, controlling the loop for the charging socket to charge the power battery to be disconnected, controlling the loop for the charging socket to supply power to the load to be connected and sending a message that the charging of the electric vehicle is ready to the power supply device.

    本申请提供了一种电动车辆和应用于电动车辆的充电方法,电动车辆包括动力电池、负载、充电插座和控制器,充电插座的一端通过高压正负直流母线连接动力电池和负载,充电插座的另一端用于连接供电装置的充电枪。在充电插座连接充电枪的情况下,控制器用于控制动力电池为并联在动力电池两端的X电容供电的回路导通;响应于X电容两端的电压达到预设值,控制器用于控制动力电池为X电容供电的回路断开,控制充电插座为动力电池充电的回路断开、控制充电插座为负载供电的回路导通、并向供电装置发送电动车辆充电准备就绪的报文。
