Title: Effective power assist system for an electric energy source in an electric or hybrid vehicle




ABSTRACT: A power assist system for reducing a load power of a primary energy source (102) in an electric vehicle based on load conditions. The system includes a primary energy source (102), a high power density device (104), a vehicle monitoring unit (106), an electric motor (114), a regenerative coupling unit (116), a switching unit (108), a level detector (110), a limiter circuit (112) and a power management system (100).  The system provides (i) additional electric power to the electric motor (114) using the high power density device (104) when the load power of the electric motor (114) exceeds a first threshold level and (ii) stores the regenerative electric energy in the high power density device (104) from the electric motor (114).
