The invention relates to the technical field of automobiles, in particular to a charging switching method and device of an electric automobile and a vehicle. The method comprises the steps that when the vehicle and a target charging pile are in charging handshake, the first charging voltage and the second charging voltage of the vehicle are obtained; obtaining a first output voltage after the handshake succeeds; when the first output voltage is equal to the first charging voltage, the charging voltage of the vehicle is switched to the first charging voltage, and a first instruction is sent to the target charging pile; when the first output voltage is equal to the second charging voltage and the second output voltage is equal to the first output voltage, the charging voltage of the vehicle is switched to the second charging voltage, and a second instruction is sent to the target charging pile; according to the invention, the maximum output capability message can be sent twice after successful handshake, two-time interaction between the charging voltage of the vehicle and the output voltage of the target charging pile is realized, the vehicle is enabled to switch different charging voltages to adapt to different voltage platforms, the operation process is simple, and the operation time is short.

    本发明涉及汽车技术领域,具体是一种电动汽车的充电切换方法、装置及车辆,方法包括:当车辆与目标充电桩充电握手时,获取车辆的第一充电电压和第二充电电压;当握手成功后获得第一输出电压;当第一输出电压与第一充电电压相等时,将车辆的充电电压切换为第一充电电压,并发送第一指令给所述目标充电桩;当第一输出电压与第二充电电压相等且所述第二输出电压与所述第一输出电压相等时,将车辆的充电电压切换为第二充电电压,并发送第二指令给所述目标充电桩;本发明握手成功后可以发送两次最大输出能力报文,实现车辆的充电电压与目标充电桩的输出电压两次交互,进而使车辆切换不同充电电压,来适配不同电压平台,且操作流程简单操作时间快。
