Electric power supply system for a vehicle and method for controlling at least one consumer unit of such electric power supply system

A method for controlling at least one consumer unit having a predetermined performance range of an electric power supply system, the electrical supply system including:

• at least one main power supply unit configured to supply electric power to the at least one consumer unit via an electric power supply line;
• and
• at least one auxiliary power supply unit configured to store a predetermined amount of electric power in at least one auxiliary electrical energy storage unit of the at least one auxiliary power supply unit to supply electric power to the at least one consumer unit as auxiliary electric power,
• the method comprising the steps of:
• determining an instantaneous amount of electric power and energy available from the auxiliary power supply unit;
• transmitting a signal representative of the instantaneous amount of electric power and energy stored in the auxiliary power supply unit to the control unit;
• and
• controlling the at least one consumer unit by the control unit in accordance with the transmitted signal.

A computer product comprising a non-transitory computer readable medium having program code which, when executed on a data processing unit in an electric power supply system including at least one consumer unit with a predetermined performance range;

• at least one main power supply unit configured to supply electric power to the at least one consumer unit via an electric power supply line;
• and at least one auxiliary power supply unit configured to store a predetermined amount of electric power in at least one auxiliary electrical energy storage unit of the at least one auxiliary power supply unit to supply electric power to the at least one consumer unit as auxiliary electric power, causes the acts of:
• determining an instantaneous amount of electric power and energy available from the auxiliary power supply unit;
• transmitting a signal representative of the instantaneous amount of electric power and energy stored in the auxiliary power supply unit to the control unit;
• and
• controlling the at least one consumer unit by the control unit in accordance with the transmitted signal.
