Claim 10:
11. A control method implemented in an electrical power-supply system including a plurality of electrical batteries, each battery comprising a plurality of cells connected in series and/or parallel, and separate switches attached to each cell or to a group of the plurality of cells, the plurality of electrical batteries comprising main batteries, which are each dedicated to delivering electrical power to a corresponding piece of consuming equipment, the method comprising, for each main battery:
acquiring the actual state of charge of the main battery,
determining the difference between the acquired actual state of charge and the theoretical state of charge and/or the slope of variation in the acquired actual state of charge,
comparing the difference with the first threshold difference and/or of the slope of variation with the first threshold slope, and
when the determined difference exceeds the first threshold difference and/or when the determined slope exceeds the first threshold slope, generating a command to perform a recharge of the main battery using a selected standby battery of the plurality of electrical batteries, while keeping the main battery connected to the corresponding piece of consuming equipment,
wherein the method further comprises
keeping the actual state of charge of each main battery at the theoretical state of charge that is determined depending on a life cycle thereof,
keeping the actual state of charge of each main battery above a threshold value, or
monitoring a power level required by each piece of consuming equipment with respect to a threshold power level.
