Battery cooling structure and a battery module
Document Type and Number:
Japanese Patent JP6208887
Kind Code:
B2
Abstract:
A battery cooling structure for efficiently cooling battery cells in a battery module is provided. Multiple columnar battery cells are housed in the battery module and are arranged in parallel to each other with gaps formed therebetween so as to form a cooling medium passage through which a cooling medium passes inside of the battery module. On the first lateral surface of the battery module, inlets for introducing the cooling medium into battery module open upstream of the cooling medium passage and are provided along gaps between the battery cells arranged nearest to the first lateral surface. On the second lateral surface of the battery module, outlets for discharging the cooling medium to outside of the battery module open downstream of the cooling medium passage and are provided along the centers in the width direction of the battery cells arranged nearest to the second lateral surface.
