Electronic fuse for a vehicle and use thereof in a vehicle

An electronic fuse comprising:

• a housing,
• a first housing terminal and a second housing terminal,
• a circuit breaker comprising a first terminal of the circuit breaker and a second terminal of the circuit breaker,
• wherein the first terminal of the circuit breaker is electrically connected to the first housing terminal of the electronic fuse,
• wherein the second terminal of the circuit breaker is electrically connected to the second housing terminal of the electronic fuse,
• wherein a thermal protection is arranged in a current path between the first housing terminal and the second housing terminal in series with the circuit breaker, and
• wherein the thermal protection interrupts the current path when a temperature of the circuit breaker and/or a temperature within the housing of the electronic fuse and/or a temperature of the housing of the electronic fuse exceeds a switch-off temperature.

An electronic fuse for a vehicle, comprising:

• a first housing terminal and a second housing terminal,
• an electronic circuit breaker comprising a control terminal, and a conduction path connected between the first housing terminal and the second housing terminal and a control terminal,
• a control device having a computer core, such as a CPU, which control device is connected to the control terminal of the electronic circuit breaker for switching on and off the electronic circuit breaker, the control device including a data interface for connection to a data communication bus of a higher-level control or computer system,
• a measuring device for detecting an operating parameter of the electronic circuit breaker and/or an electrical connection in which the electronic circuit breaker is arranged, wherein the operating parameter represents a magnitude of a current and/or a magnitude of a voltage and/or a magnitude of an electrical output and/or a magnitude of an electrical power and/or a temperature and/or a deformation of the electrical connection,
• a temperature sensor for determining a temperature of the electronic fuse or for determining a temperature of a component, assembly, or unit, arranged externally of the electronic fuse,
• wherein the control device receives an evaluation signal representing a measured value of the temperature sensor and compares the evaluation signal to a reference signal representing a temperature limit value, and
• wherein the control device signals an exceeding of the reference signal by the evaluation signal to the higher-level control or computer system via the data interface.
