Abstract

A method of super extending and optimising the travel distance/range of Electric Vehicles (EVs) is introduced. The method introduced provides a novel improvement to the field of design and conversion of electromechanical energy for Electric Vehicles or Hybrid Vehicles, based on Energy Storage Systems (ESS). The existing EV prior art provides for the maximisation of range, based on the State of Charge and kilowatt-hour (kWh) capacity of the ESS and the efficient use of the "as is" onboard energy available. The introduction and application of the method introduced is not limited to EVs only. The method can be applied to many other devices, machines, tools, power generation plants for utilities, Unmanned Aerial Vehicles(UAVs), standalone power generation equipment, remote Information and communication technology power sites, and many other applications which require power for their operation, but not limited to the afore-mentioned list. The ESS can be replaced at the end of its economic life, while the rest of the EV components, parts or devices can also be maintained so as to extend the overall EV economic life or utility.

Description

1. Description

The present invention provides a novel improvement or solution to the range limitations of prior art EV or Hybrid Vehicles, but not limited thereto.

2. Field of Invention

The invention relates generally to ESS-based utilisation and the application of the FGS in diverse fields such as: - Transportation; - Renewable and Conventional Power Generation; - Information and Communication Technologies (ICT); - Medical and Healthcare Fields; - Automation; - Production and Manufacturing Industries; - Marine Industries; - Mining and Exploration industries; - Construction & Domestic Appliances, Tools and Devices; - Agricultural Mechanisation Industries; - Defence and Aerospace Applications; but not limited thereto. 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. The invention comprises of a system made up of: at least one ESS pack, EV or Hybrid drive systems, traction and control systems, EV or hybrid control systems and ESS optimisation configurations for EV or Hybrid systems, but not limited to EVs or Hybrid Vehicies. In the case of stationary or mobile equipment or tool applications the system will comprise of at least one ESS pack, on-board computer or control module, charging or ESS management system, a primary motor, a primary generator for feedback charging, but not limited thereto.
