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 following steps: acquiring a first voltage of a battery; according to the first voltage, determining a target working mode of the LLC circuit, the target working mode being a full-bridge mode or a half-bridge mode; and controlling the LLC circuit to work according to the target working mode. Therefore, the dynamic switching of the working modes of the LLC circuit can be realized according to the battery voltage, the generation of uncontrolled rectification current is avoided, the charger can safely, stably and reliably work in various working conditions, and the control mode is simple and efficient.
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,方法包括:获取电池的第一电压;根据第一电压,确定LLC电路的目标工作模式,目标工作模式为全桥模式或半桥模式;控制LLC电路按照目标工作模式进行工作。由此,可以根据电池电压实现LLC电路的工作模式的动态切换,避免产生不控整流电流,使得充电机安全稳定、可靠地工作在各种工况,并且控制方式简单、高效。
