Abstract: The present disclosure provides a battery pack, which comprises a base plate and at least one battery module. Each battery module comprises: a battery group; two end plates respectively positioned at two ends of the battery group in the Y direction; and two side plates respectively positioned at two ends of the battery group in an X direction. Each battery module is fixed to the base plate, and one of the side plates of each battery module faces the base plate. The structure of the battery pack is simple and the assembling of the battery pack is convenient. Compared with the positive arrangement of the traditional battery module, the battery pack greatly improves the space utilization of the battery pack and reduces the overall size and weight of the battery pack.
