Abstract
A practical hybrid vehicle comprising an internal combustion engine, a generator powered by the engine, and a storage battery which has a large capacity but is not heavy. The storage battery consists of electric double layer capacitors. Electric power generated by the generator is supplied to the battery via a charger having a constant-current characteristic to recharge the battery. The charger can consist mainly of a current-output type switching regulator. Electric power stored in the battery is supplied via an output converter to an electric motor which drives the wheels.
