A method manages energy of a hybrid vehicle. The vehicle includes a heat engine, one or more electric traction motors, a high-voltage traction battery, a low-voltage on-board battery for accessories of the vehicle, a current inverter to transform direct currents into alternating currents for the electric motor, and a reversible current transformer to convert high-voltage current into low-voltage current of the on-board battery and to use a stock of energy available in the low-voltage battery to not draw energy from the high-voltage battery when it has a relatively low level of charge. The method includes determining an operating point of the vehicle involving a minimum fuel consumption in the heat engine by imposing on the electric motor a torque that minimizes a criterion of total fuel consumption by the consumption of the heat engine, power consumed in the traction battery, and power consumed in the on-board battery.
