Abstract

A temperature sensing member is located between two adjacent battery cells, and includes a main body part arranged in parallel to one surface of the battery cell, and a temperature measuring unit mounted on the main body part and measuring the temperature of the battery cell. The main body part has a plate shape. The temperature measuring unit is inserted into one side of the main body part.

First claim

1 . A temperature sensing member located between two adjacent battery cells, the temperature sensing member comprising:
a main body configured to be arranged in parallel to one surface of the battery cell, and a temperature measurer mounted on the main body and measuring the temperature of the battery cell, wherein the main body has a plate shape, and wherein the temperature measurer is inserted into a first side of the main body.

2 . The temperature sensing member of claim 1 , wherein the first side has a protruding shape.

3 . The temperature sensing member of claim 1 , wherein the measurer includes a temperature sensor, and
wherein the temperature sensor is located at a first point of the main body.

4 . The temperature sensing member of claim 3 , wherein the first point is a point located a first distance from the first side, and
wherein the first distance has a value of 5 to 20% of a length of the main body.

5 . The temperature sensing member of claim 1 , wherein the temperature measurer includes a connector for forming an electrical connection with an external device, and
wherein the connector is arranged so as to protrude from the main body.

6 . The temperature sensing member of claim 1 , wherein a thickness of the main body is 0.3 mm to 0.7 mm.

7 . The temperature sensing member of claim 1 , wherein the main body is made from polypropylene (PP) or polycarbonate (PC).

8 . A battery module comprising the temperature sensing member of claim 1 .

9 . A battery pack comprising the temperature sensing member of claim 1 .
