The invention relates to a vehicle-mounted low-voltage power supply management method, device and equipment and a medium, and the method comprises the steps: keeping a solar cell in a charging state and monitoring the output voltage of the solar cell in real time when determining that a solar energy saving mode of a vehicle-mounted low-voltage power supply management system is in an open state; when it is determined that the output voltage is smaller than or equal to a first threshold value, the current whole vehicle low-voltage power supply state is adjusted to enable a whole vehicle low-voltage power supply small battery to supply power to a whole vehicle electrical system, and a solar cell stops supplying power; when it is determined that the output voltage is larger than a second threshold value, the current whole vehicle low-voltage power supply state is adjusted to enable a solar cell to supply power to a whole vehicle electrical system, and a whole vehicle low-voltage power supply small battery stops supplying power; wherein the first threshold value and the second threshold value are preset minimum power supply voltage and standard voltage for normal work of the whole vehicle electronic control unit respectively. According to the invention, solar energy can be efficiently utilized to reduce the power consumption of the whole vehicle electrical system to the low-voltage power supply small battery of the whole vehicle.

    本公开涉及一种车载低压供电管理方法、装置、设备及介质,该方法包括:确定车载低压供电管理系统的太阳能节能模式处于开启状态时,保持太阳能电池处于充电状态并实时监测太阳能电池的输出电压;确定所述输出电压小于或等于第一阈值时,调整当前整车低压供电状态为整车低压供电小电池为整车电气系统供电、太阳能电池停止供电;确定所述输出电压大于第二阈值时,调整当前整车低压供电状态为太阳能电池为整车电气系统供电、整车低压供电小电池停止供电;其中,所述第一阈值和第二阈值分别为预设的整车电子控制单元正常工作的最低供电电压和标准电压。本公开能够实现通过对太阳能的高效利用来减少整车电气系统对整车低压供电小电池的电能消耗。
