Title:

BATTERY PACK AND ELECTRICALLY CONDUCTIVE MEMBER

Document Type and Number:

WIPO Patent Application WO/2018/055676

Kind Code:

A1

Abstract:

A battery pack of an embodiment is provided with a plurality of battery cells, a connecting member, an electrically conductive member, and a heat conducting unit, for example. The plurality of battery cells each respectively has an electrode terminal part. The electrically conductive member has: a plate-shaped first terminal part connected with the connecting member; a plate-shaped second terminal part connected with the electrode terminal part; and a plate-shaped bridge part, provided spanning the first terminal part and the second terminal part, that fuses by heat including self-generated heat. The heat conducting unit is provided on a first portion from a first terminal part to the bridge part of the electrically conductive member, and heat conduction is performed so that the temperature of a first end part of the bridge part in the width direction of the bridge part is higher than the temperature of a second end part on the side opposite to the first end part of the bridge part.
