Abstract
A traction battery for an electrically or semi-electrically driven vehicle. The traction battery includes at least one temperature sensor. The temperature sensor is configured as an infrared sensor and includes a sensor array having several sensor elements for spatially resolved detection of the temperature of a surface of one or more components of the traction battery. A deflection optic is arranged between the respective surface and the sensor array, via which optic the temperature sensor detects the respective surface.

A traction battery for an electrically or semi-electrically driven vehicle, wherein the traction battery comprises:
- a battery module housing having an interior region bounded by interconnected walls, said interconnected walls including a top wall,
- at least one temperature sensor in the form of an infrared sensor that includes a sensor array having several sensor elements for spatially resolved detection of a temperature of a surface of one or more components of the traction battery, and
- a deflection optic arranged in the interior region of the battery module housing and above the surface,
- wherein the temperature sensor detects the temperature of the surface via the deflection optic,
- wherein the deflection optic and the infrared sensor are arranged in the interior region of the battery module housing and are each suspended from the top wall of the housing and spaced apart from the top wall of the housing,
- wherein an optical axis of the infrared sensor is arranged in a longitudinal direction of the vehicle, and
- wherein the deflection optic is angled relative to the top wall and the optical axis of the infrared sensor.
