The invention relates to a vehicle, a vehicle-mounted charger and a control method of the vehicle-mounted charger, belongs to the field of vehicles, and can reduce the requirement for the capacity of a bus capacitor, improve the overall efficiency and reduce the cost. The control method of the vehicle-mounted charger comprises the following steps: acquiring a preset battery allowable minimum voltage of a power battery and a current battery voltage of the power battery under the condition that power grid access is detected; and if the current battery voltage is lower than the preset battery allowable minimum voltage, increasing the voltage of the bus capacitor by reducing the resonance gain of the isolation DC/DC circuit until the voltage of the power battery is detected to reach the preset battery allowable minimum voltage.

    本公开涉及一种车辆、车载充电机及其控制方法,属于车辆领域,能够降低对母线电容容量的需求,提高整机效率,降低成本。一种车载充电机的控制方法,包括:在检测到电网接入的情况下,获取所述动力电池的预设电池允许最低电压和所述动力电池的当前电池电压;若所述当前电池电压低于所述预设电池允许最低电压,则通过降低所述隔离DC/DC电路的谐振增益来提升所述母线电容的电压,直至检测到所述动力电池的电压达到所述预设电池允许最低电压。
