Battery pack

The utility model aims to provide the battery pack so as to solve the technical problems in the prior art that the temperature difference between the upper part and the lower part is large and the service life of a battery cell is easily shortened because only the bottom of the battery cell is cooled. The battery pack comprises a box cover, a box body, a battery module, a bottom liquid cooling plate and a plurality of side liquid cooling plates, the battery module is assembled in the box body and comprises a plurality of battery cells which are arranged side by side; the bottom liquid cooling plate is positioned below the battery module so as to dissipate heat of the bottom of the battery cell; the side face liquid cooling plates are located on the side faces of the battery modules to dissipate heat of the side faces of the battery cells, and the side face liquid cooling plates extend along the side faces of the battery cells. 本实用新型的目的在于提供一种电池包，以解决现有技术中仅对电芯底部进行散热而导致上下温差较大、易缩短电芯使用寿命的技术问题。电池包包括：箱盖、箱体、电池模组、底部液冷板
