System for charging the battery (6) of an automotive vehicle furnished with at least one electric or hybrid traction chain comprising an electric machine (2) connected mechanically to the driving wheels and connected electrically on the one hand to an electrical supply network (1) and on the other hand to the battery (6) by way of an inverter (5). The charging system comprises, when the vehicle is on charge, the electric machine (2) and the inverter (5) of the traction chain as well as a control system able to control the inverter (5) so that the energy is tapped off from the electrical supply network (1) through the electric machine (2) and to the battery (6), while controlling the electric machine (2) in such a way that it does not produce any wheel torque.
