AC chargers are divided into single-phase AC chargers and three-phase AC chargers, which control the input of AC power to the electric vehicle, and then convert into DC power to charge the battery by OBC on the vehicle. Due to the OBC volume, the power is relatively small, generally not more than 22KW, and the charging speed is relatively slow.
The DC charger can convert the AC into DC, and directly charge the battery, so the volume is not limited. The maximum power of the PNE's DC charger can reach 360kW, which can realize ultra fast charging.
