ELECTRICAL POWER SUPPLY SYSTEM FOR A VEHICLE

A method for managing the use of an on-board motor vehicle battery charger. The vehicle including a supply battery, the on-board charger being connected, on the one hand, to the battery and being intended to be connected, on the other hand, to an electrical power supply network that is external to the vehicle and is able to provide a three-phase voltage. Each network phase is characterized by a maximum overall usage power. The on-board charger includes a plurality of conversion modules, each conversion module includes a plurality of elementary power conversion units that are independent of one another. Each elementary unit being characterized by a maximum usage power threshold. Each conversion module being intended to be connected to an external power supply network phase.
