METHOD FOR RECOVERING ELECTRICAL ENERGY IN A VEHICLE WITH REGENERATIVE BRAKING

摘要

Method for recovering electrical energy in a vehicle with regenerative braking. The method according to the invention for recovering electrical energy in a motor vehicle with regenerative braking is used in a vehicle equipped for this purpose with an electrical capacitance device (5) to store electrical energy supplied by a rotary electrical machine (4) of the vehicle during regenerative braking operation. According to the invention, a choice is made, on the basis of the initial rotational speed of the rotary electrical machine (4) to apply an energy recovery stratagem from at least the following two: - a first energy recovery stratagem that favours high power supplied by the rotary electrical machine (4); and - a second energy recovery stratagem that favours high efficiency of the rotary electrical machine (4).
