The invention discloses a charging unit for a quick-change battery of an electric vehicle, an electric vehicle battery changing station and an energy storage station. The charging unit is used for charging the quick-change battery of the electric vehicle and comprises a charger and an electric connection seat which are arranged in a charging space, wherein the charger comprises a DC output interface which is electrically connected with the electric connection seat, and the electric connection seat comprises a high-voltage post terminal and is used for realizing electric connection with the quick-change battery. According to the charging unit, the length of a direct-current wire between the charger and the electric connecting seat is greatly shortened, wiring difficulty is reduced, and wiring cost is also reduced; on the other hand, the charger is directly connected with the electric connection seat in the charging unit, so electromagnetic interference among the charging units is avoided, and data transmission is more timely and accurate. In addition, each electric connection seat and each charger are arranged together in a centralized manner, and each charging unit is arranged separately, so the heat dissipation area is greatly increased, and damage of the charger caused by the temperature rise of the charger is further avoided.
本发明公开了一种电动汽车快换电池的充电单元、电动汽车换电站及储能站,充电单元用于给电动汽车的快换电池充电,包括设于充电空间内的充电机和电连接座;充电机包括直流输出接口,直流输出接口与电连接座电连接;电连接座包括高压极柱,用于实现与快换电池之间的电连接。本发明中的充电单元大大缩短了充电机和电连接座间直流电线的长度,降低了布线难度,也减少了布线成本;另一方面,通过在充电单元将充电机和电连接座直接相连,避免各充电单元间电磁干扰,也进一步使数据传输更为及时、准确。另外,每一电连接座与每一充电机集中布置在一起,每一充电单元分开布置,从而大大增加了散热面积,进一步避免了充电机温度升高造成的充电机的损坏。
