Abstract: An automatic cyclical charging system for electric vehicles including a plurality of battery jars connected in series, a direct current conversion alternator (UPS), a transformer stabilizer, and a charger. The battery jars output electric currents, which are converted to alternating currents. The alternating currents are transformed and stabilized before supplying to the charger for charging another battery jar unit that is in use, without using the power supplied by the vehicle's alternator. Therefore, the electric vehicle may have a continuous supply of electricity.
