BATTERY PACK AND ELECTRIC VEHICLE

This application relates a battery pack and an electric vehicle. The battery pack includes a housing provided with a bottom surface and a top surface. A battery assembly is arranged in the housing. The battery assembly includes a structural reinforcing member and a cell sequence formed by connecting multiple cells. An outer surface of the cell includes a bottom surface, a top surface, first lateral surfaces, and two opposing second lateral surface. The bottom surface of the cell faces the bottom surface of the housing, and the top surface of the cell faces the top surface of the housing. The first lateral surface has a largest area. The multiple cells are arranged with second lateral surfaces thereof facing each other to form the cell sequence, and the structural reinforcing member is fixedly bonded with a first lateral surface of each cell in the cell sequence. The battery assembly abuts with the bottom surface of the housing to be supported in the housing.
