Abstract: The present invention relates to a method for managing an electric circuit (1) of a motor vehicle, comprising: at least one low-power component (11) requiring a minimum operating voltage, a high-power component (13), a power supply source (3) for the, or at least one, low-power component and for the high-power component, the method comprising the following steps: the voltage drop engendered by the energizing of the high-power component (13) is calculated as a function of the internal resistance of said high-power component, the power of the high-power component (13) is limited so that the residual voltage upon the voltage drop due to the energizing of the high-power component (13) is greater than or equal to the minimum operating voltage of the, at least one, low-power component (11).

Abstract: The invention relates to an engine system (10) comprising a circuit (21) for the recirculation of burnt gases from a heat engine (17) equipped with a turbocharger (13, 19), in which the recirculation circuit (21) comprises am energy recovery turbine (30) receiving high-pressure exhaust gases upstream of the turbocharger.

Abstract: The invention relates to an electrical network (1) for a vehicle, comprising: a first circuit (2) comprising a first power source (7) and at least one first electronic component (8) powered by the first power source (7); and a second circuit (3) comprising a second power source (10) and at least one second electronic component (11) which can be activated and is powered by the second power source (10). The network (1) also comprises: a connecting member (5) between the first (2) and second (3) circuits, said connecting member (5) allowing, in a first configuration, an exchange of current of a first value between the first circuit (2) and the second circuit (3) and, in a second configuration, an exchange of current of a second value between the first circuit (2) and the second circuit (3), in which the second value is lower than the first value; and a control unit (17) which controls the configuration of the connecting member (5).

Abstract: A method for controlling an electrical compressor (11) forming part of an assembly comprising an internal combustion engine and an electric machine (15), the compressor (11) being configured to compress the intake air of the internal combustion engine, the electrical compressor being capable of being powered with electricity by:—first electrical energy provided by an electrical energy storage unit (10), and—second electrical energy coming from the electric machine (15) when it is driven in rotation, said method involving:—imposing a setpoint value on at least one electrical or mechanical variable of the assembly, and—at least temporarily supplying the electrical compressor (11) with the first and second electrical energy in such a way that the value of said variable approaches the setpoint value.
