The invention provides a vehicle insulation fault positioning method and device, electronic equipment and a storage medium. The method comprises the steps that when an insulation fault occurs to a vehicle, the vehicle is controlled to be powered off; contactors of all parts of the high-voltage system of the vehicle are sequentially disconnected, and whether the parts are fault parts or not is detected based on an insulation detector of the high-voltage system of the vehicle; determining whether the fault component affects driving of the vehicle; if the fault part affects running of the vehicle, the high-voltage system of the vehicle is not powered on after the vehicle is powered on next time; and if the fault part does not affect the running of the vehicle, the high-voltage system of the vehicle is powered on after the vehicle is powered on next time, and the fault part is not connected with the high-voltage system of the vehicle. In the mode, fault parts can be automatically determined, and maintenance personnel do not need to exclude equipment one by one; and whether the fault part affects the running of the vehicle can be determined, so that the vehicle can continue to run after the insulation fault is sent until the vehicle enters the station for maintenance.

    本发明提供了一种车辆的绝缘故障定位方法、装置、电子设备和存储介质。其中,该方法包括:当车辆发生绝缘故障后,控制车辆下电;依次断开车辆的高压系统的各个部件的接触器,基于车辆的高压系统的绝缘检测仪检测部件是否为故障件;确定故障件是否影响车辆的行驶;如果故障件影响车辆的行驶,在车辆下次上电后车辆的高压系统不上电;如果故障件不影响车辆的行驶,在车辆下次上电后车辆的高压系统上电且故障件不连接车辆的高压系统。该方式中,可以自动确定故障件,不再需要维修人员逐个设备排除;还可以确定故障件是否影响车辆的行驶,从而使车辆可以在发送绝缘故障后继续行驶,直至进站维修。
