Abstract: A system charges a traction battery of an at least partially electric traction vehicle. The system includes an input filter connected to a power supply network. The filter includes a capacitance connected through a switch of the filter between at least one power supply phase connection or a neutral connection of the charging system, and a ground of the charging system. The system includes a controller for charging parasitic capacitances of the charging system without transferring energy from the power supply network to the battery while the power supply network is connected to the charging system. The system includes a time delay for closing the switch of the filter when a delay time frame higher than or equal to a predetermined time frame expires. The system also includes a charging activator for transferring energy between the power supply network and the battery, the switch of the filter being closed.

Abstract: A device for charging a battery, in particular a battery of an electric traction motor vehicle, on the basis of a single-phase power supply network, including a filtering stage intended to be connected to the single-phase network, a voltage step-down stage connected to the filtering stage, a voltage step-up stage intended to be connected to the battery and coupled to the voltage step-down stage via an inductive component such as an induction coil, a regulating unit able to impose chopping duty ratios on the voltage step-down stage and on the voltage step-up stage. The regulating unit includes means for compensating for the phase shift between the imput current of the voltage step-down stage and the imput voltage of the voltage step-down stage.
