The invention provides a vehicle-mounted power supply switching circuit and a vehicle, and the vehicle-mounted power supply switching circuit comprises a micro-control unit MCU, a first power supply, a second power supply, an acquisition circuit, and a switching device. The output ends of the first power supply and the second power supply are connected with the input end of the acquisition circuit, the output end of the acquisition circuit is connected with the input end of the MCU, and the output end of the MCU is connected with the switching device; the acquisition circuit is used for acquiring a first parameter set of the first power supply and a second parameter set of the second power supply; the MCU is used for determining whether the MCU is connected with a second power supply or not, and if the MCU is connected with the second power supply, determining whether each parameter of the second parameter set meets a preset condition corresponding to the parameter or not; and the MCU is also used for switching the first power supply to the second power supply through the switching device if each parameter of the second parameter set meets a preset condition corresponding to the parameter, so that the second power supply supplies power to the load.

    本申请提供了一种车载电源切换电路及车辆,其中,车载电源切换电路包括:微控制单元MCU、第一电源、第二电源、采集电路和切换装置;第一电源和第二电源的输出端与采集电路的输入端相连,采集电路的输出端与MCU的输入端连接,MCU的输出端与切换装置连接;采集电路,用于采集第一电源的第一参数集合和第二电源的第二参数集合;MCU,用于确定是否与第二电源连接,若与第二电源连接,则确定第二参数集合的各项参数是否满足该项参数对应的预设条件;MCU,还用于若第二参数集合的各项参数均满足该项参数对应的预设条件,则通过切换装置将第一电源切换为第二电源,以使第二电源为负载供电。
