Abstract
A vehicle comprises an internal combustion engine, a battery, an alternator, a starter, configured to start the internal combustion engine, a charger, distinct from the battery, and an electrical energy storage system, connected to the starter and to the charger, and distinct from the battery. To allow the engine to be started in case of a battery failure, a method for operating the vehicle comprises: starting the internal combustion engine, measuring a state of charge of the battery, comparing the measured state of charge with a predetermined threshold value, if the measured state of charge is lower than the predetermined threshold value: charging the electrical energy storage system with the charger, then starting the internal combustion engine with the starter, by powering the starter with the electrical energy storage system, when restarting the internal combustion engine is required.
