A charger, a slow start method, an electric vehicle and a charging system.The charger comprises a control module, a DC-DC conversion circuit and a first capacitor, when the electric vehicle is charged, the control module in the charger can firstly control the DC-DC conversion circuit to charge the first capacitor through battery electric energy output by a battery system; and after it is determined that the capacitor voltage of the first capacitor reaches the first threshold voltage, the charging pile is instructed to output charging electric energy. According to the charger, a slow start circuit does not need to be arranged in the slow start process, the circuit of the charger is simplified, and the miniaturization design of the charger is achieved.

    一种充电机、缓启动方法、电动汽车及充电系统,其中,充电机包括控制模块、DC‑DC转换电路和第一电容,在向电动汽车充电时,充电机中的控制模块可以先控制DC‑DC转换电路利用电池系统输出的电池电能对第一电容充电,在确定第一电容的电容电压达到第一阈值电压后,再指示充电桩输出充电电能。该充电机在缓启动过程中不需要设置缓启动电路,有助于简化充电机的电路,实现充电机的小型化设计。
