PROBLEM TO BE SOLVED: To provide a storage battery system capable of achieving both deformation prevention of storage batteries due to group pressure and temperature averaging of the storage batteries.SOLUTION: In a configuration in which a plurality of storage batteries 11 are built-in and connected to each other in a storage battery housing box and a partition plate is arranged between individual storage batteries 11. On the surface (short-side side surface 12A) orthogonal to the lamination direction α of a pole plate in a battery jar 12, a rib 12R is formed, and surface contact between the battery jar 12 of the storage battery 11 and a side plate of the partition plate is made possible without forming the rib in the surface (long-side side surface 12B) in the horizontal direction. The partition plate has a cavity part that enables convection of air, and the storage battery housing box is provided with a slit in communication with the cavity part. |
