A device and method for detecting when at least one heat source exceeds a temperature threshold. The device includes a component having an electrical resistance that varies according to the operating temperature of the component, and an electrical power source suitable for supplying an electrical current to the component. The component is configured to be thermally coupled to the heat source, such that the operating temperature varies according to the temperature of the heat source and the heat released in the component by the Joule effect, the variable electrical resistance having a high value if the operating temperature is greater than a triggering threshold, the electrical power source being configured to generate the electrical current such that the operating temperature is greater than or equal to the triggering threshold once the temperature of the heat source is greater than or equal to the temperature threshold.

A housing for a battery includes an envelope and at least one rupture device provided with a rupture cap. The rupture device is mounted at the location of an opening formed in the envelope. The rupture cap breaks when an excess pressure is exerted on its outer surface situated on the outer side of the housing.
