PROBLEM TO BE SOLVED: To provide a stable storage battery system in a small height which does not contact electrical components even if an electrolytic solution of the secondary battery leaks.SOLUTION: There is provided a secondary battery system comprising: a secondary battery 38; a storage battery control unit 39 configured to perform control by recognizing a state of the secondary battery 38; a charge/discharge control part 42 configured to control charging and discharging of the secondary battery 38; and a fan 45 configured to cool the charge/discharge control part 42. The secondary battery 38 is formed of a plurality of storage battery modules MDL1-MDL6, which form a plurality of left-and-right pairs, and the plurality of left-and-right pairs are provided in a vertical direction. A charge/discharge control part 42 is provided above a battery housing part 220 in which the secondary battery 38 is housed. A heat-radiating fin 235 provided in the charge/discharge control part 42 is provided in an air duct of a fan 45. |
