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.
