Patent ID: 11699818

Abstract:
Provided is a battery pack capable of improving load resistance of a reinforcing part and protecting battery cells inside a case. The battery pack 100 includes a reinforcing part 30 that is in contact with a bottom wall 10e of the case 10. The reinforcing part 30 extends in one direction D1 along the bottom wall 10e, and has dimensions d1, d2 in directions orthogonal to the one direction D1 that are larger than thickness t of side walls 10a, 10b, 10c, 10d of the case 10 and of the bottom wall 10e. The reinforcing part 30 has a pair of end fixed parts 31 that are fixed to both ends of the battery module 20 in the one direction D1, and an intermediate fixed part 32 between the pair of end fixed parts 31 and fixed to the battery module 20 or the case 10.
