The present invention relates to a method for controlling the brake energy recovery in a micro-hybrid system (1) comprising at least one rotary electric machine (2) and an electrochemical battery, said micro-hybrid system (1) being provided in a vehicle. The method comprises a step of controlling, when the electrochemical battery (8) has a first predetermined energy state corresponding to an initial optimal charge state (CBth1), a reduction of said first energy state to a second energy state corresponding to an intermediate charging state so as to provide a charging capacity during an eventual occasion of electric energy recovery during a braking phase of the vehicle.
