The invention discloses a power supply method and equipment for vehicle-mounted equipment, and the power supply method for the vehicle-mounted equipment comprises the steps: controlling a standby power supply to supply power to the vehicle-mounted equipment of a vehicle when the vehicle is not ignited and started; when the standby power supply supplies power to vehicle-mounted equipment of the vehicle, electric quantity information of the standby power supply is obtained in real time; according to the electric quantity information, whether the current electric quantity of the standby power supply is smaller than first preset electric quantity is judged; and when the current electric quantity of the standby power supply is smaller than the first preset electric quantity, controlling the standby power supply to stop supplying power to the vehicle-mounted equipment. By adopting the technical scheme, the problem that the vehicle cannot be started due to power shortage of the main power supply of the vehicle can be avoided; and the standby power supply can be prevented from being lack of electricity and is protected from being damaged.
本发明公开了一种车载设备的供电方法、设备,车载设备的供电方法包括在车辆未点火启动时,控制所述备用电源为所述车辆的车载设备供电;在所述备用电源为所述车辆的车载设备供电时,实时获取所述备用电源的电量信息;根据所述电量信息,判断所述备用电源的当前电量是否小于第一预设电量;在备用电源的当前电量小于第一预设电量时,控制所述备用电源停止为所述车载设备供电。采用上述技术方案,可以避免车辆的主电源亏电,造成车辆无法启动的问题;还可以防止备用电源亏电,保护备用电源不被损坏。
