| 摘要 |
The invention relates to a method and device for supplying a charge with electric energy recovery. According to the invention, an electric current, which circulates from the battery (UB) through the electric motor (M) and th e diode (D1), charges capacitors (CA and CB) which are connected in parallel. Once charged, said capacitors are connected in series, thereby producing a voltage difference in relation to the battery and causing half of the charge from the capacitors to be returned through the diode (D2) to the battery. Moreover, once reconnected in parallel, the capacitors are re-charged, said charge being equal to that which was previously conveyed from the capacitors to the battery. In this way, as the capacitors are connected cyclically in parallel and in series, the energy is conveyed from the battery to the capacitors and from the capacitors to the battery, thereby considerably prolonging the autonomy of the battery and the operation of the motor.</SDOA B>
