A method for managing a motor vehicle including a first battery connected to an alternator and an electrical network, the alternator operable either at a positive low alternator voltage or a high alternator voltage higher than the low alternator voltage, the method including: estimating a potential recharging current strength that the first battery could absorb if it was, at that moment, powered by the high alternator voltage; estimating a first alternator yield corresponding to a current rotation speed of the alternator, and to a strength of consumed current actually fed into the network; estimating a second alternator yield corresponding to the current rotation speed of the alternator and to the sum of strengths of a potential recharging current of the battery and of the consumed current; and imposing a high alternator voltage if the difference between the first yield and the second yield is higher than a first threshold. |
