PROBLEM TO BE SOLVED: To provide a battery pack capable of improving safety.SOLUTION: A battery pack has a battery array, side plates, a top cover, and end plates. The battery array has a plurality of battery cells aligned in a first direction. The battery array is formed in a hexahedron configured by (1-1)th, (1-2)th, (2-1)th, (2-2)th, (3-1)th, and (3-2)th planes. The top cover is provided to the (1-1)th plane of the battery array, and has reinforcement frames on both sides by using the first direction as a reference. Each reinforcement frame includes a vertical frame and a horizontal frame, and is formed to have an L-shaped cross section. The end plates are provided to the (3-1)th plane and the (3-2)th plane, and fixed to the top cover. The side plates are provided to the (2-1)th plane and the (2-2)th plane. Fixed parts respectively pressing both lateral faces of the top cover provided to the (1-1)th plane are formed to the respective side plates. At least one or more first weight-saving hole can be formed to the side plates. |
