Abstract

Disclosed is a battery cell including an electrode, a housing, a cell interior inside the housing, a temperature sensor, and a heat-conducting part which differs from the electrode, is entirely or partially disposed inside the housing of the battery cell, and is thermally connected to the temperature sensor.

First claim

What is claimed is:

1. A battery cell comprising:
an electrode;
a housing;
a cell interior which is located inside the housing;
a temperature sensor mounted entirely outside of the housing on an exterior wall of the housing; and
a thermally conductive part that is arranged separately from the electrode, is entirely arranged in the housing of the battery cell, is arranged on an inner wall of the housing directly across from the temperature sensor, and is thermally connected to the temperature sensor;
wherein the thermally conductive part is in direct thermal contact with the cell interior; and
wherein the thermally conductive part is formed from an electrically insulating material.

2. The battery cell as claimed in claim 1 , wherein the thermally conductive part is in direct thermal contact with the temperature sensor.

3. The battery cell as claimed in claim 1 , wherein
the thermally conductive part is arranged in the cell interior.

4. The battery cell as claimed in claim 1 , wherein the thermally conductive part comprises a thermally conductive material.

5. A high-voltage battery comprising:
at least one battery cell including:
an electrode;
a housing;
a cell interior which is located inside the housing;
a temperature sensor mounted entirely outside of the housing on an exterior wall of the housing; and

a thermally conductive part that is arranged separately from the electrode, is entirely arranged in the housing of the battery cell, is arranged on an inner wall of the housing directly across from the temperature sensor, and is thermally connected to the temperature sensor;
wherein the thermally conductive part is in direct thermal contact with the cell interior; and
wherein the thermally conductive part is formed from an electrically insulating material.

6. An electric vehicle or hybrid vehicle comprising:
at least one high-voltage battery including:
at least one battery cell including:
an electrode;
a housing;
a cell interior which is located inside the housing;
a temperature sensor mounted entirely outside of the housing on an exterior wall of the housing; and

a thermally conductive part that is arranged separately from the electrode, is entirely arranged in the housing of the battery cell, is arranged on an inner wall of the housing directly across from the temperature sensor, and is thermally connected to the temperature sensor;
wherein the thermally conductive part is in direct thermal contact with the cell interior; and
wherein the thermally conductive part is formed from an electrically insulating material.
