Abstract: A battery is provided that uses supercapacitors and battery cells connected by switches among themselves and to input and output terminals via multiplexed selection under the control of a microprocessor or microcontroller. The supercapacitors and battery cells of the battery may independently, or in combination, power an electric vehicle. The battery may be operated in several modes, at least one of which may be used to power an electric vehicle long enough to reach a charging station in connection with charge on the battery cells being partially or almost completely depleted. The battery may also deliver charge while the battery cells and/or the supercapacitors are being charged. The battery may be fast charging on-the-run in that the supercapacitors may be charged faster than the battery cells permitting an electric vehicle to be powered without spending considerable time, that would otherwise be required at a conventional charging station with traditional batteries.
