The invention provides a generator self-checking method and device and a vehicle. The method comprises the steps that when the low-voltage side of a vehicle is powered on and the voltage of the high-voltage side of a direct-current charger is pre-charged to a first pre-charging voltage, self-inspection is conducted on the high-voltage side of a BSG; after the BSG high-voltage side is successfully self-detected, detecting whether the voltage of the BSG low-voltage side meets a preset condition or not; and when the voltage of the low-voltage side of the BSG meets a preset condition, performing self-inspection on the low-voltage side of the BSG. The self-checking success rate of the BSG low-voltage side can be improved.

    本发明提供一种发电机自检的方法、装置及车辆。该方法包括:当车辆低压侧上电,且直流充电器的高压侧的电压预充至第一预充电压时,对BSG高压侧进行自检;当所述BSG高压侧自检成功后,检测BSG低压侧电压是否满足预设条件;当BSG低压侧电压满足预设条件时,对所述BSG低压侧进行自检。本发明能够提高BSG低压侧自检成功率。
