Charging current control method

According to the charging current control method provided by the invention, the maximum charging current of the charger is dynamically adjusted according to the power grid harmonic Tr, the effective value Vr and the peak voltage Vp of an input power supply of the charger, so that the pollution of overlarge charging current to a power grid under a special working condition is avoided, and the adverse effect of voltage/current ripples on the service life of the charger and the service life of a battery is avoided; and abnormal operation of the generator caused by overlarge charging current is avoided. 本发明提供了一种充电电流控制方法，根据充电器输入电源的电网谐波Tr、有效值Vr、峰值电压Vp情况动态调节充电器的最大充电电流，避免特殊工况下过大的充电电流对电网造成污染，避免电压/电流纹波对充电器和电池的寿命造成不利影响，避免过大的充电电流造成发电机工作异常。
