There are currently approximately 16 Million EV's in the World today of various makes, models, and types. Regardless, each type requires periodic charging of the batteries and the number of batteries on board determines the vehicle range. These 16 million cars consume roughly 30 Terawatt-Hours (TWh) of electricity per year, the equivalent of all the electricity generated in the country of Ireland. A hydrogen powered battery charger embedded in the vehicle can create additional green energy to extend the range of the vehicle for a small cost of hydrogen, and can be added after market regardless of the vehicle brand or model, since there are no engines, transmissions, or rear drive assemblies are as found in typical fossil fuel vehicles today. The generator is a PEM type module connected to a electric alternator or DC generator which is housed within the vehicle in a small footprint. Such a unit can have an expected life cycle of some 20 years or more.
