Abstract: A rapid charging device for a battery includes a filtering stage of resistive-inductive-capacitive type to be connected to a three-phase network, a buck stage, a boost stage to be connected to the battery, an induction winding interposed between the buck stage and the boost stage, and a regulating unit capable of imposing chopping duty cycles on the buck stage and on the boost stage. The regulating unit compensates the phase shift induced by the filtering stage between the currents and the voltages taken from each phase of the three-phase network and also maintains the value of the current amplitude passing through the winding above a non-zero predefined threshold.

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.
