More particularly, the invention provides significant benefits to the automotive and transportation industry regarding the super extension or continued operation of the range of EVs or Hybrid Vehicles, with reduced or no need for external source recharging during the time of operating the EV or Hybrid Vehicle, but not limited hereto.
3. Background of the Invention
The global quest for the introduction and uptake of green and renewable energy sources to reduce emissions, as well as the keen interest in the EV and Hybrid Vehicle market development, have been key drivers for the invention. Historically, the considerations of the detrimental environmental impact of transportation and automotive industries related emissions have led to the introduction of Hybrid and Electric Vehicles, The present state of the art EVs or Hybrid Vehicles experience the challenge of range limitations, due to either depletion of on-board ESS of fuel during its operation. This has led to the reserved uptake of the EV or Hybrid Vehicle market, especially when the infrastructure for recharging EVs is not geographically, conveniently or readily available, so as to allow for the frequency or speed of commercial recharging and transactions. The main hindrance being the limited on- board ESS capacity, which provides only for a designer specified or limited travel range, as well as the time it takes to recharge at stopover points, leading to longer travel times or delays.
4. Obiect of the Invention
The broad object of the invention is to provide a method of on-board electricity generation for Electric or Hybrid Electric Vehicles which utilise ESS, so as to extend the range and reduce or eliminate the anxiety associated with the need of having to recharge or run out of on-board ESS energy before reaching the destination. The FGS method provides requisite recharging of the on-board ESS, to ensure sufficient reserve energy to travel or return to place of original departure. The method introduced is not limited to EVs or Hybrid Vehicles only, and ail the intellectual property rights to the application or use of the FGS method are claimed, as per the field of invention in section 4 above.
5. Summary of the invention
The method presented superlatively extends the range or operation time of EVs, and all other equipment devices, systems wherever the ESS-based FGS or FGS system will be applied or used.
