The invention provides a two-stage charger power balancing method, a charger controller, a readable storage medium and an electric vehicle. The power balancing method comprises the following steps: acquiring an actual input current and an actual input voltage of a charger; determining the target output power of the charger according to the actual input current and the actual input voltage of the charger; controlling the output current or the output voltage of the charger according to the target output power of the charger; acquiring actual output voltage and actual output current of the charger; determining target input power of the charger according to the actual output voltage and the actual output current of the charger; and controlling the input current of the charger according to the target input power of the charger. According to the invention, by adopting a closed-loop adjustment mode, the response speed of output or input can be accelerated when input or output changes, so that the problem of unbalanced voltage of an intermediate bus when input or output changes is relieved to a great extent, the robustness of the charger can be effectively improved, and the service life of the charger can be effectively prolonged.

    本发明提供了一种两级式充电机功率平衡方法、充电机控制器、可读存储介质和电动车辆,该功率平衡方法包括:获取充电机的实际输入电流和实际输入电压;根据充电机的实际输入电流和实际输入电压,确定充电机的目标输出功率;根据充电机的目标输出功率,控制充电机的输出电流或输出电压;获取充电机的实际输出电压和实际输出电流;根据充电机的实际输出电压和实际输出电流,确定充电机的目标输入功率;根据充电机的目标输入功率,控制充电机的输入电流。本发明通过采用闭环的调节方式,可以在输入或输出发生变化时,加快输出或输入的响应速度,从而极大程度地缓解了输入或输出发生变化时中间母线电压不平衡的问题,进而能够有效提高充电机的鲁棒性和寿命。
