Abstract

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.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 65 words
A hybrid vehicle having wheels, comprising: an electric power-generating means for producing electric power; electric double layer capacitors to which said electric power produced by said electric power-generating means is supplied via an electric charger to recharge said electric double layer capacitors; and an electric motor for driving the wheels, said electric motor being driven by electric power supplied from said electric double layer capacitors.
Claim 2
Dependent Claim 65 words
A hybrid vehicle having wheels, comprising: an electric power-generating means for producing electric power; electric double layer capacitors to which said electric power produced by said electric power-generating means is supplied via an electric charger to recharge said electric double layer capacitors; and an electric motor for driving the wheels, said electric motor being driven by electric power supplied from said electric double layer capacitors.
Claim 3
Dependent Claim 31 words
The hybrid vehicle of claim 1, wherein said electric double layer capacitors are connected in series, and wherein voltage-equalizing means are connected in parallel with said electric double layer capacitors, respectively.
