Abstract
The invention relates to a battery charging device which comprises a storage power supply unit, a changing-over distributor and a power generator. The storage power supply unit comprises n basic battery units and n super capacitors, all the basic battery units and the super capacitors are in parallel connection to form battery and capacitor sets, and the battery and capacitor sets in series connection supply power to an electric vehicle. The battery and capacitor sets are connected with the changing-over distributor which is connected with an anode and a cathode of the power generator. Anodes and cathodes of the basic battery units are opposite to the anode and the cathode of the power generator. When the basic battery units are charged, power transmission source is supplied to drive the power generator which generates electric power, the changing-over distributor charges the battery and capacitor sets in circulating changing-over mode, and instantaneous electric quantity is temporarily stored by the super capacitors and supplied to the basic battery units. Electric power is supplied by serially connecting a battery, and charging voltage is reduced by the circulating changing-over charging mode to avoid danger caused by over-high charging voltage to a human body.
