A battery device designed so that a plurality of battery modules (1) are arranged in rows at given spaces in a enclosure (2). Turbulence accelerators (5), such as dummy battery units or the like, are provided in a position on the uppermost-stream side of the enclosure in which air flows in the direction of arrangement of the battery modules. The heat transfer ability for the battery modules in the upper-stream position is enhanced by the turbulence accelerators which disorders the airflow introduced into the enclosure. Auxiliary coolant intake ports (7) for the introduction of a coolant are provided in the middle of an airflow path, whereby the heat transfer ability on the lower-stream side is enhanced, so that battery temperature differences between the battery units arranged in the enclosure can be restrained. Thus, a simple-construction battery device is realized enjoying improved quality and operation stability.

1. A battery device having an enclosure formed with a coolant intake port, a plurality of battery units arranged in rows at given spaces in the enclosure, and a coolant flow path extending in a direction of arrangement of the plurality of battery units and around them, the improvement comprising:a turbulence accelerator configured to disorder a coolant flow, said turbulence accelerator being provided in the enclosure between the cooling intake port and battery units of the plurality of battery units that are disposed on an uppermost-stream side, as viewed from the coolant intake port, of said coolant flow path.
