Abstract: A method for managing the charge state of a battery includes activating a float-charge phase of the battery, in which the battery is intermittently charged with a view to maintaining the charge state thereof above a predetermined target charge-state value. The method also includes detecting critical conditions of use of the battery likely to prevent the battery charge state from being maintained above the predetermined target charge-state value and increasing the predetermined target charge-state value when the critical conditions of use of the battery are detected, such as to anticipate activating the battery float-charge phase.
