A battery pack comprises battery modules and interface modules, a preset number of groups of battery modules and a preset number of groups of interface modules are connected with each other to form a frame structure, the interface modules are used for being connected with a vehicle body, electric connecting pieces are arranged between the battery modules, and the electric connecting pieces penetrate through the interface modules to enable the battery modules to be electrically connected. According to the battery pack, the battery modules are connected and spliced into a frame structure with a preset size and a preset structure through the interface modules with different structural shapes and sizes, and the frame structure is used as a strength component, such as a frame and an auxiliary frame, so that the original strength components such as the frame and the auxiliary frame in a whole vehicle are replaced; therefore, the design space of the whole vehicle can be saved to a great extent, and materials are sav
