Abstract

This disclosure relates to a method for the management of the electrical current supply in a motor vehicle having a combustion engine, wherein the charge state of a battery is detected and characterized as a discrete variable that indicates whether the prevailing charge state is below or above a calibrated threshold value. If the discrete variable indicates that the prevailing charge state is below the calibrated threshold value, the battery is charged using a relatively high voltage over a predetermined time period in such a manner that all cells of the battery are charged. If the discrete variable indicates that the prevailing charge state is above the calibrated threshold value, different temperature-dependent voltage set points of an electric generator in the vehicle are set in dependence upon a prevailing energy conversion efficiency level of the drivetrain that is detected and characterized as a further discrete variable.
