<p>The system comprises:
an electrical generator (1) which can be driven by the motor vehicle's engine,
a first storage battery (2) which is connected to the generator (1) by means of a power line (3) and is intended to be connected to the normal user devices (5); and
a second battery (6) or auxiliary battery which is connected to the power line (3) and is intended to be connected to the priority user devices (9). The second battery (6) is connected to the power line (3) by means of a controlled unidirectional dc/dc converter (11) which can permit the transfer of energy solely from the line (3) to the second battery (6), and with which is associated an electronic control system (12, 13; 14) which is arranged
to estimate the charge state of the second battery (6) in accordance with predetermined procedures, and
to control the dc/dc converter (11) in a manner such as to regulate the supply of electrical energy from the power line (3) to the second battery (6) so that the estimated charge state of the second battery (6) tends towards a predetermined reference value (R).</p> |
