The invention relates to a vehicle-mounted terminal secondary battery charging circuit and a vehicle-mounted terminal secondary battery charging method, and relates to the field of vehicle-mounted terminals. The vehicle-mounted terminal secondary battery charging circuit comprises a solar charging panel, a vehicle internal power supply, a secondary battery, a micro control unit (MCU), a secondary battery power supply circuit, an MCU power supply circuit, a first power supply selection switch and a second power supply selection switch. The vehicle internal power supply is arranged in the charging circuit, and corresponding wiring is carried out correspondingly, so that the vehicle internal power supply is connected with the secondary battery and the MCU. In the charging process, when the solar charging panel cannot be used, a mode of supplying power to the secondary battery and the MCU through the vehicle internal power source can be switched through a current magnitude comparison mode, and when the current capable of being provided by the solar charging panel is small, the efficiency of charging the secondary battery and supplying power to the MCU at the same time is guaranteed.
本申请关于车载终端二次电池充电电路及车载终端二次电池充电方法,涉及车载终端领域,该车载终端二次电池充电电路包括:太阳能充电板、车辆内部电源、二次电池、微控制单元MCU、二次电池电源电路、MCU电源电路、第一电源选择开关以及第二电源选择开关。通过在充电电路中进行车辆内部电源的设置,并对应进行相应的接线,使车辆内部电源与二次电池以及MCU均建立有连接关系。在进行充电的过程中,当无法利用太阳能充电板时,可以通过电流大小的比较方式,切换至通过车辆内部电源对于二次电池和MCU进行供电的模式,在太阳能充电板可提供的电流较小时,保证同时向二次电池进行充电,并向MCU进行供电的效率。
