The invention discloses a standby power supply control method and device and a vehicle, and the method comprises the steps: obtaining the voltage of a storage battery when the storage battery supplies power; if the voltage of the storage battery is smaller than a low-voltage threshold value, the vehicle state is obtained, and a standby power switch of a standby power supply is controlled to be switched on to replace the storage battery for power supply; and after a standby power supply switch for controlling a standby power supply is closed, determining an executed control power supply strategy according to the vehicle state. Therefore, no extra equipment cost needs to be increased, and the power battery can be used as a standby power supply of the vehicle only by connecting part of battery cells in the middle of the power battery in series. When it is detected that the voltage of the storage battery is low, low-voltage power supply of the vehicle in a short time is guaranteed by starting the standby power supply, meanwhile, according to the specific vehicle state of the vehicle, safety control is conducted on the vehicle power supply through different power supply control strategies, and therefore the driving safety of the vehicle is further improved.
本发明公开一种备用电源控制方法、装置及车辆,通过在蓄电池供电时,获取蓄电池电压;若所述蓄电池电压小于低压阈值,则获取车辆状态,并控制备用电源的备用电源开关闭合,以代替蓄电池供电;在控制备用电源的备用电源开关闭合之后,根据所述车辆状态,确定执行的控制电源策略。如此,无需额外增加设备成本,只需将动力电池中间的部分电芯串联即可作为车辆的备用电源。当检测到蓄电池电压较低时,通过启用备用电源,保证短时间内车辆的低压供电,同时根据车辆具体的车辆状态,通过不同的控制电源策略,对车辆电源进行安全控制,从而进一步提高车辆的行车安全。
