Abstract

A battery pack includes: a battery cell; a temperature detection element; and a thermally conductive member transferring heat of the battery cell to the temperature detection element.

First claim

1 . A battery pack comprising:
a battery cell; a temperature detection element; and a thermally conductive member transferring heat of the battery cell to the temperature detection element.

2 . The battery pack according to claim 1 ,
wherein the thermally conductive member is disposed in an area including at least a portion facing a heat generating portion of an electronic-device main body in which the battery pack is installed.

3 . The battery pack according to claim 1 ,
wherein at least part of the thermally conductive member coats a periphery of the battery cell.

4 . The battery pack according to claim 1 ,
wherein the thermally conductive member is a thermally conductive sheet including a thermally conductive layer, and a first electrically insulating layer and a second electrically insulating layer that are arranged on both surfaces of the thermally conductive layer.

5 . The battery pack according to claim 1 ,
wherein the battery cell has a shape like a plate, the temperature detection element is disposed on a side of the battery cell having a shape like a plate, and the thermally conductive member is disposed over at least a plate surface and the side of the battery cell.

6 . The battery pack according to claim 5 ,
wherein the temperature detection element is mounted on a circuit board electrically connected to the battery cell, and is disposed on the side of the battery cell having a shape like a plate.

7 . The battery pack according to claim 1 ,
wherein the thermally conductive member directly touches the temperature detection element.

8 . The battery pack according to claim 1 ,
wherein the thermally conductive member touches the temperature detection element via a thermally conductive material.

9 . The battery pack according to claim 1 ,
wherein the thermally conductive member has a first portion touching the battery cell, and a second portion protruding from the first portion and touching the temperature detection element.

10 . An electronic device comprising:
a battery pack including a battery cell; a temperature detection element; and a thermally conductive member transferring heat of the battery cell to the temperature detection element.

11 . The electronic device according to claim 10 ,
wherein the thermally conductive member has a first portion touching the battery cell, and a second portion protruding from the first portion and touching the temperature detection element.

12 . The electronic device according to claim 10 ,
wherein the battery pack includes the temperature detection element.

13 . The electronic device according to claim 10 ,
wherein an electronic-device-main-body side in which the battery pack is installed includes the temperature detection element.
