Abstract: The present invention introduces a retrofit method of regenerative braking where no components of an automobile are to be replaced or removed and none of their functionality is modified. The recovering energy system is implemented as an additional, one piece, complete device, placed onto the existing automobile wheel's hub, and covered by the automobile's wheel. The system includes a housing, turbines, accumulators, and valves which act to both store and dispel energy as needed. This method of regenerative braking is therefore applicable to all the automobiles, independent or their power source, to newly built automobiles and those already on the road.

Abstract: While the concept of saving automobile's intake of fuel or electricity by converting kinetic energy of an automobile into some form of potential energy, usually either electrical potential or compressed gas potential, in order to later convert that energy back into kinetic energy, has been well recognised over the years, and while the number of regenerative braking techniques and devices have been introduced over the years, with the exception of an electrical engine/generator, these techniques have not been well adapted. That was caused in part by either not a very simple implementation of those devices or by a necessity to completely re-engineer automobile powertrain in order to use those techniques. Present invention introduces a method of regenerative braking where no components of an automobile are to be replaced or removed and none of their functionality is modified.
