The invention provides an electric vehicle high-voltage power-on control method and device and a vehicle. The method comprises the steps that when a high-voltage power battery is in a starting state, the high-voltage power battery is controlled to power on a high-voltage load; under the condition that the high-voltage load is powered on successfully, the opening value of a brake pedal and gear information of a gear shifter are obtained, and the gear information is information of a gear where the gear shifter is located currently; and under the conditions that the opening value of the brake pedal is larger than the preset opening value and the gear information is a driving gear or a reverse gear, the high-voltage power battery is controlled to power on the driving motor. The method solves the problem that the service life of the driving motor is shortened due to the fact that the driving motor is still in a high-voltage working state when the electric vehicle is standby in the prior art.

    本申请提供了一种电动汽车高压上电的控制方法、控制装置和车辆,该方法包括:在高压动力电池处于启动状态下,控制高压动力电池给高压负载上电;在高压负载上电成功的情况下,获取制动踏板的开度值和换挡器的挡位信息,挡位信息为换挡器当前所处的挡位的信息;在制动踏板的开度值大于预设开度值且挡位信息为驱动挡位或者倒车挡位的情况下,控制高压动力电池给驱动电机上电。该方法解决了现有技术中电动汽车待机时仍使驱动电机处于高电压工作状态导致驱动电机寿命缩短的问题。
