The embodiment of the invention discloses a charging control method and device for a new energy vehicle and a charging circuit, and the method comprises the steps: controlling a voltage conversion circuit to convert the electric energy of a first voltage into the electric energy of a second voltage in a process of charging a battery through a charging circuit, and supplying the electric energy of the second voltage to the vehicle for low-voltage power consumption, the second voltage is smaller than the first voltage; detecting the working state of the voltage conversion circuit in real time; and if the voltage conversion circuit works abnormally, controlling to stop charging the battery. According to the scheme, in the process of charging the vehicle power battery, the voltage conversion circuit is synchronously controlled to convert the high voltage into the low voltage to be supplied to the low-voltage equipment of the vehicle, and the charging process is carried out only when the voltage conversion circuit works normally, so that the low-voltage equipment can work normally; and the condition that the low-voltage storage battery is lack of electricity in the charging process is also avoided.

    本申请实施例公开了一种新能源车辆的充电控制方法、装置及充电电路,其中,方法包括:在通过充电线路为电池充电的过程中,控制电压转换电路将第一电压的电能转换为第二电压的电能并供给车辆低压功耗,所述第二电压小于所述第一电压;实时检测所述电压转换电路的工作状态;若所述电压转换电路工作异常,控制停止对所述电池充电。上述方案在为车辆动力电池充电的过程中会同步的控制电压转换电路将高压电转换为低压电供给车辆低压设备,只有在电压转换电路正常工作的状态下才会进行充电进程,从而保证各低压设备能够正常工作,也避免了充电过程中低压蓄电池亏电的情况发生。
