Disclosed is a monitoring device (DS) fitted to a vehicle (V) comprising an electric power train and an on-board network (RB) supplied with electrical energy by a power supply unit comprising a low-voltage rechargeable battery (BS) and at least one electric power generator (GE). The device (DS) comprises a processor (PR) and a memory performing operations which consist in, when the electric power train is started, triggering the isolation of the low-voltage rechargeable battery (BS) of the electric power generator (GE), triggering a test of the low-voltage rechargeable battery (BS) to determine an average minimum voltage at its terminals and an average internal resistance, and then determining the state of the low-voltage rechargeable battery (BS) according to the determined mean minimum voltage and average internal resistance.
