Abstract
This storage battery module includes battery cells, a first plate-shaped member, and a second plate-shaped member opposing the first plate-shaped member across an insulating member. The first plate-shaped member has conductors formed therein. The second plate-shaped member has formed therein a heat dispersion region opposing at least a portion of the conductors of the first plate-shaped member across the insulating member. Heat generated in the conductors of the first plate-shaped member is transferred to the heat dispersion region of the opposing second plate-shaped member, and the heat is dispersed inside the heat dispersion region.
Claims4
A storage battery module comprising:
- battery cells;
- a first plate-shaped member having first connecting conductors formed therein, the first connecting conductors (i) being conductors that electrically connect together terminals of the battery cells that are adjacent to one another, and (ii) being separated from one another by a first insulator;
- and
- a second plate-shaped member having a heat dispersion region formed by a member that has a thermal conductivity that is greater than or equal to a second threshold, the heat dispersion region opposing at least a portion of the first connecting conductors of the first plate-shaped member across an insulating member having a thickness that is less than or equal to a first threshold in a direction perpendicular to a main surface of the first plate-shaped member, to cause heat transferred from the first connecting conductors to be dispersed into the heat dispersion region.
