Problems solved by technology

[0003] However, in Japanese Patent Laid-Open No. 2017-201587, since an external cooler or refrigerant is required to cool the battery cells, the battery pack becomes complicated.
Therefore, there is still room for further improvement in the heat dissipation measures of the battery pack

Abstract

The invention provides a battery pack and a battery module using the same. The battery pack comprises a plurality of battery cells which are arranged in a horizontal direction and on which a waterproof measure is applied, the direction orthogonal to the arrangement direction being the longitudinal direction; and a plurality of resin frames that are respectively provided between the adjacent battery cells, support the both end portions of the battery cells in the longitudinal direction, and form openings that expose the lower surfaces of the battery cells.

Description

technical field [0001] The present invention relates to a battery pack and a battery module using the battery pack. Background technique [0002] In the battery module described in Japanese Patent Application Laid-Open No. 2017-201587, a lower surface case constituting a part of the battery pack and housing the battery cells is provided. The lower case is configured to be able to house the battery cells individually, and covers the outer surface of the battery cells. In addition, an exposed portion exposing the battery cell is partially formed on the lower case, and the battery cell can be cooled by bringing an external cooler or refrigerant into contact with the battery cell through the exposed portion. [0003] However, in Japanese Patent Application Laid-Open No. 2017-201587, since an external cooler or refrigerant is required to cool the battery cells, the battery pack becomes complicated. Therefore, there is room for further improvement in the heat dissipation measure...
