The invention discloses a power supply control system applied to a vehicle-mounted power supply device. The power supply control system comprises a diode, a vehicle-mounted power supply end, a voltagejudgment circuit, a power supply circuit, a charging circuit, a charging enabling control circuit and a battery input end, and is characterized in that one end of the diode is simultaneously connected with the voltage judgment circuit and the vehicle-mounted power supply end, and the voltage judgment circuit is connected with the power supply circuit; the other end of the diode is simultaneouslyconnected with the battery input end and the charging circuit, and the charging circuit is connected with the voltage judgment circuit through the charging enabling control circuit. The power supply control system is particularly suitable for the vehicle-mounted power supply device, the corresponding power supply working path judgment can be made according to different working voltages, and the device can be used for output and input under different power supply voltages, namely a power supply wire harness is used for output under a certain condition, and is also used as a power supply input wire of an external charging device to charge a battery of the device when the device does not work.
本发明公开了一种应用于车载电源设备内的供电控制系统,包括二极管、车载供电端、电压判断电路、供电电路、充电电路、充电使能控制电路和电池输入端,二极管一端同时与电压判断电路和车载供电端连接,电压判断电路与供电电路连接,二极管另一端同时与电池输入端和充电电路连接,充电电路通过充电使能控制电路与电压判断电路连接。尤其适用于车载电源设备内,针对不同的工作电压做出相应电源工作路径判断,实现设备在不同的电源电压下即做输出又做输入用。即电源线束在一定的情况下作为输出用,在设备不工作时又作为外部充电设备电源输入线给设备的电池充电用。
