Despite many improvements in the autonomy of electric vehicles, we are obliged to recognize that the production of batteries remains expensive, which is cosecante the prices raised electric vehicles for a severely reduced autonomy compared to thermal vehicles.
I looked at the problem of the autonomy of electric vehicles to observe that it will be very difficult or impossible to obtain sufficient autonomy by adding to the infinite batteries and have vehicles at a reasonable price to to make them available to more people.
Noting this, I imagined and succeeded in developing various inventions allowing substantial savings on the volume of batteries and filed a patent in 2015, concerning a battery charge rebreather NOMADES, which I named " SPRING-FORCE "
I filed several patents in this direction and had the concept examined by an electromechanical engineer, who my realistic calculations; showing the interest of the system able to double the autonomy of the batteries compared to the claims of the manufacturers, from the first cycle of operation of the device. The system is designed to be easily installed on all electric vehicles and plug-in hybrids without significant modifications.
