Abstract: A system and method for management of electrical powering of at least one piece of electrical equipment by a power supply battery of a motor vehicle including an internal combustion engine. The motor vehicle includes a system for automatically stopping and restarting the internal combustion engine. The system and method: determine a charge status of the power supply battery; compare the charge status of the power supply battery with a predefined threshold value; and control cutting off of the power supply to the at least one piece of electrical equipment during an automatic restarting of the internal combustion engine if the charge status of the power supply battery is lower than the predefined threshold value.

Abstract: A system for generation of electric power on-board a motor vehicle of the type that includes a fuel cell, a reformer for supplying the fuel cell with hydrogen-rich gas, an air-compression device, and a control unit used to control the operation of the reformer. The reformer includes a main cold-plasma reformer and an auxiliary cold-plasma reformer that are mounted in parallel upstream of the fuel cell. In addition, a control valve, which is controlled by the control unit, is mounted upstream of the two cold-plasma reformers to supply compressed air, fuel, and water vapor either to the main reformer alone or to both reformers simultaneously.

Abstract: Method and apparatus for regulating a converter having transistors, in which the value of a number N1 of state variables is measured and stored, then action is carried out on a number N2 of control variables. N1 being greater than N2, the value of the control variables is calculated, at a given instant, for a number P of periods such that the product of N2 multiplied by P is greater than or equal to N1.
