The invention relates to a vehicle-mounted power supply vehicle control method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: acquiring an output voltage value of a vehicle-mounted power supply voltage converter; under the condition that the output voltage value is larger than a preset output voltage upper limit value, the charge state and the pole temperature of a low-voltage storage battery of the vehicle-mounted power supply are obtained; and under the condition that the charge state exceeds a state upper limit value or the pole temperature exceeds a temperature upper limit, executing a preset output voltage value control instruction of the vehicle-mounted power supply voltage converter, and reducing an output voltage value of the vehicle-mounted power supply voltage converter. By adopting the method, the current of the external power supply of the vehicle and the power supply of the storage battery can be prevented from flowing back into the DC/DC converter under the condition of not increasing hardware cost, so that the reliability of a low-voltage power supply network of the whole vehicle is improved and the failure rate of a low-voltage system is reduced.
本申请涉及一种车载电源整车控制方法、装置、计算机设备、计算机可读存储介质和计算机程序产品。所述方法包括:获取车载电源电压变换器的输出电压值;在所述输出电压值大于预设输出电压上限值的情况下,获取车载电源的低压蓄电池的荷电状态和极柱温度;在所述荷电状态超过状态上限值或所述极柱温度超过温度上限的情况下,执行车载电源电压变换器的预设输出电压值控制指令,降低车载电源电压变换器的输出电压值。采用本方法能够在不增加硬件成本的情况下,能避免车辆外接电源及自身蓄电池电源电流反灌进DC/DC变换器,从而提升整车低压电源网络可靠性以及降低低压系统故障率。
