The invention relates to a charger control method and device, a charger and a vehicle. The method is applied to the charger, the charger is a vehicle-mounted charger or a charging pile charger, and the method comprises the steps that the current voltage, the current current and the bus capacitor voltage of the alternating current side of the charger are acquired; determining a steady-state target current and a current correction value of an alternating current side; determining a target current value of the alternating current side according to the current voltage and the steady-state target current; correcting the target current value by using the current correction value; according to the target current value, the current voltage, the current current and the bus capacitor voltage obtained after correction, the current of the alternating current side is controlled so that the current of the alternating current side can follow the target current value obtained after correction. The target current value is corrected by using the current correction value, so that the accuracy of the target current value obtained after correction can be ensured, the current on the alternating current side closely follows the target current value obtained after correction, the deviation of the positive and negative half-cycle current on the alternating current side is avoided, and the actual current balance degree on the alternating current side is adjusted.

    本公开涉及一种充电机控制方法、装置、充电机及车辆。方法应用于充电机,充电机为车载充电机或充电桩充电机,包括:获取充电机的交流侧的当前电压、当前电流及母线电容电压;确定交流侧的稳态目标电流和电流校正量;根据当前电压和稳态目标电流,确定交流侧的目标电流值;利用电流校正量对目标电流值进行校正;根据校正后所得的目标电流值、当前电压、当前电流及母线电容电压,控制交流侧的电流,以使得交流侧的电流跟随校正后所得的目标电流值。利用电流校正量对目标电流值进行校正,可保证校正后所得的目标电流值的准确性,使得交流侧的电流密切跟随校正后所得的目标电流值,避免交流侧正负半周电流出现偏差,以调整交流侧实际电流平衡度。
