The invention relates to an electric vehicle battery pack, a charging device, a charging system and a charging method, and belongs to the technical field of new energy vehicles. The electric vehicle battery pack is composed of a battery pack of an electric vehicle, a battery pack power circuit and a liquid cooling or/and heating pipeline in the battery pack, and when the electric vehicle is charged, the battery pack power circuit is connected with a charging power circuit of the charger. And the liquid cooling or heating pipeline in the battery pack is respectively connected with the heating device and the refrigerating unit through a liquid pipeline outside the battery pack. Compared with a common electric automobile with a liquid temperature control device, a heating control component and a refrigeration control component are reduced, and the cost of the whole automobile is reduced; the whole vehicle mass is reduced, so that the vehicle energy consumption is reduced; the liquid temperature control device is combined with the charging device, so that the charging can be managed in a centralized manner, the battery cooling or heating efficiency is higher, and the control is simpler and more convenient; and heat can be utilized in a centralized mode when the vehicles are charged in a centralized mode, and economic benefits are improved.

    本申请涉及一种电动车电池组、充电装置、充电系统及充电方法,属于新能源汽车技术领域。电动车电池组由电动汽车的电池组、电池组电力线路和电池组中的液体冷却或/和加热管路组成,电动汽车充电时,电池组电力线路与充电机的充电电力线路连接,电池组中的液体冷却或加热管路通过电池组外部液体管路分别与加热装置和制冷机组连接。与通常的带有液体温控装置的电动汽车相比,减少了加热控制部件及制冷控制部件,降低了整车成本;降低了整车质量,从而降低车辆能耗;液体温控装置与充电装置相结合,可以对充电集中管理,电池冷却或加热效率更高,控制更简单、方便;在车辆集中充电时可以将热量进行集中利用,提高经济效益。
