1. A combined electric device for powering and charging, comprising: an alternating-current motor; an inverter; accumulation means; and switching means for allowing one of powering of the motor or charging of the accumulation means by the inverter, wherein the switching means are incorporated into the inverter and comprise at least one H-bridge structure for each phase of the motor, and wherein, in the charging of the accumulation means by the inverter, the accumulation means is charged from an electricity network by using the windings of the alternating-current motor as an inductor and by using a midpoint of the at least one H-bridge structure as a connecting point for the electricity network.
