Abstract
A method is provided for controlling a power supply system of an automotive vehicle that includes at least one battery and at least one associated battery managing unit adapted to monitor the state of charge of the battery. During an off state of the vehicle, the state of charge level of each battery is monitored by the battery managing unit. If the state of charge monitored reaches a low state of charge threshold, an on-board communication device adapted to emit a critical state of charge level alarm to be received by an off-board reception device is activated. The power supply system includes a battery managing unit per battery and an alarm to emit a critical state of charge level alarm.
