Device for measuring temperature of an accumulator battery

The sensor has an long body with two lateral walls and base. The body has a cradle for a thermistor and slots for conductors. A cover (20) is designed to be inserted between the walls and its end is attached to an elastic strap (22) designed to cooperate with the thermistor. A locking system is provided to ensure cover fixing on the sensor body. Temperature sensing module including a support designed to be placed on a battery. The support has a conduit designed to receive a sensor which has an insulating material body in which are conductors connected to a thermistor situated in front of an opening, in the body, and against which is applied and elastic strap (22). The strap is folded and cooperates with a ramp in the conduit so that the at the end of insertion of the sensor into the conduit, the thermistor is against the battery. A locking system (25,26) locks the sensor into the conduit.
