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