1. A voltage regulator for an alternator, said alternator being connected to a battery (13) with a charging cable and to consuming devices to supply the consuming devices with a voltage, the voltage being determined by a temperature (TB) of the battery (13) according to a predetermined relationship between the temperature (TB) and the voltage for optimum charging of the battery (13), said voltage regulator including a control means (17), said control means (17) having data storage means (DS) for storing data and simulation means (PR) cooperating with the data storage means (DS) so that at least one of the temperature (TB) of the battery (13) and a voltage drop (UL) on the charging cable (11) is calculated by the simulation means (PR) from the stored data in the data storage means (DS), the data storage means being structured to store heating and cooling time constants of the battery (13).
