Embodiment Construction

[0024] exist figure 1 In the preferred embodiment shown, the load is constituted by a DC motor (M), the first energy storage device is constituted by a battery (UB) and the second energy storage device is constituted by a pair of capacitors (CA) and (CB). figure 1 It is shown that the motor (M) is connected between a battery (UB) of a certain voltage and a first capacitor (CA) and a second capacitor (CB) through two possible The switching contacts (S1) and (S2) are connected in parallel with each other. . These capacitors (CA, CB) are charged through the motor (M) and diode (D1) to obtain a voltage level equal to the battery (UB), the charge Q = (CA+CB)UB, while in capacitors (CA) and (CB) During charging, the motor (M) rotates.

[0025] Once charged, the two capacitors (CA) and (CB) are connected in series via switching contacts (S1) and (S2), at which point their voltage increases to a value twice the voltage of the battery (UB) such that the charge Q = [(CA+CB) / 2]2UB=(C...

Abstract

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 the 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.

Description

technical field [0001] The present invention relates to a method and apparatus for the recovery of electrical energy by means of an automatic rechargeable power supply in which the current flowing from a battery or battery through a load, such as a motor, is fully returned to the battery or battery through an electrical circuit, thereby greatly extending the its scope. [0002] In particular, the two capacitors, connected cyclically from parallel to series and vice versa, are charged by the motor during the parallel connection, while in the series connection, when the voltage doubles, they bring power back to charge the battery again. The power supply is a closed system that does not require an external supply of energy, except to compensate for the losses incurred, the range of the battery being defined by the number of charges and discharges permitted by the same technology. Background technique [0003] A load like a motor is connected to a battery or accumulator with a ...
