Abstract: A method manages a network of storage batteries for supplying electric current to an engine of an electrically propelled motor vehicle. The network includes a first storage battery and at least a second storage battery connected in parallel, each storage battery being connected to the rest of the network via a relay which enables the storage battery to be isolated from every other storage battery. The method includes acquiring a state of charge for each storage battery, determining, by a computer, a control setpoint for each relay based on the acquired states of charge, and controlling the relays based on each determined control setpoint. In the acquiring, the computer acquires a value of a first parameter relating to a level of wear of each storage battery. In the determining, each control setpoint is determined based on the value of the first parameter.
