This device for charging a battery and/or for retrieving electrical energy from said battery, in particular for a traction system of an automotive vehicle with at least partially electric traction, comprises a first rectifier stage (7) intended to be linked to a power supply network or to a load, a second inverter stage (8) intended to be linked to the battery and regulating means acting on the first and second stages. It comprises a bypass branch (11) linked between an output and an input of the inverter stage and comprising a breaker (11-1) that can be opened during charging and which is associated with a diode (11-2) positioned in such a way as to permit a return of current to the first rectifier stage. |
