Provided is a storage battery board that makes it possible to cool each of a plurality of storage batteries as equally as possible regardless of whether said batteries are positioned upstream or downstream of an airflow that is made to circulate within the storage battery board by an induced draft blower device. This storage battery board (1) comprises: a battery pack (3a) that is included in an upper battery pack group (Gu), and a battery pack (3b) that is included in a lower battery pack group (Gl). An induced draft blower device (7) provided to a top plate section of a housing (5) discharges air in the upper section of the housing (5) to outside and takes in outside air from a bottom plate section of the housing (5). Therefore, the battery pack (3a) is supplied with air that has a higher temperature as a result of absorbing heat from the battery pack (3b), but an airflow resistance adjustment member (13a) reduces airflow resistance so that the battery pack (3a) has high cooling efficiency. In contrast, the battery pack (3b) is cooled by air having a lower temperature, but the airflow resistance adjusted by an airflow resistance adjustment member (13b) is larger so that the battery pack (3b) has lower cooling efficiency. Thus, it is possible to nearly equalize the temperatures of the battery packs (3a, 3b) regardless of the positions thereof within the storage battery board (1). |
