Vehicle power supply network comprising means of protection against thermoelectric risk. The invention relates to a vehicle power supply network (1), comprising: - a power source (2), - distribution boxes (12, 13, 14) electrically connected to the power source (2) and comprising electronic switching components (Cl1, Cl2, Cl3, C1, C2, C3, T4, T5, T6, Cn) upstream of electrical consumers (A11, A12, E11, E12, L11, L12), the power supply network (1) comprising a monitoring device (122, 132, 142) for a measurement related to the use of one of the electronic switching components (C1, C2, T4, T5, T6) located upstream of one of the electrical consumers (A12, E12, L12), the measurement being distinct from a current measurement or temperature, the monitoring device (122, 132, 142) being capable of cutting off the power supply to the electrical consumer (A12, E12,L12) as soon as the measurement data exceeds a predetermined threshold.

An electrical receptacle including an outlet and a testing circuit. The outlet is configured to connect to an external load. The outlet includes a phase line and a neutral line. The testing circuit is configured to output a signal to a phase line of the outlet, receive a response signal from a neutral line of the outlet, and determine when the external load is electrically connected to the outlet based on the response signal.

The invention relates to an electrical power-supply network (1) on board a vehicle, the electrical power-supply network comprising: - an energy source (2); - distribution boxes (12, 13, 14) electrically connected to the energy source (2) and comprising electronic switching components (Cl1, Cl2, Cl3, C1, C2, C3, T4, T5, T6, Cn) upstream of electrical loads (A11, A12, E11, E12, L11, L12), the electrical power-supply network (1) comprising a monitoring member (122, 132, 142) for monitoring a measurement datum linked to the use of one of the electronic switching components (C1, C2, T4, T5, T6) located upstream of one of the electrical loads (A12, E12, L12), the measurement datum being distinct from a current or temperature measurement, the monitoring member (122, 132, 142) being able to cut off a supply of power to the electrical load (A12, E12, L12) as soon as the measurement datum is higher than a predetermined threshold.

A predefined peak current value for a system that includes a transfer switch system, a first power source, a downstream transformer, and a downstream circuit breaker is obtained. A sensed current value for some components of the system are obtained by sensors of the system. A corresponding semiconductor switch assembly of the first power source is instructed to turn off in response to determining a fault in the electrical distribution system using the sensed current value and the predefined peak current value. A reference current is obtained for the downstream circuit breaker. An updated sensed current value is obtained. The corresponding semiconductor switch assembly of the first power source is instructed to turn on based on an integrated value of the updated sensed current value matching an integrated value of the reference current, where turning on and off the switch is repeated until the downstream circuit breaker clears the fault.
