Abstract

A method for controlling power sources or energy sinks on an energy accumulator, in particular for a motor vehicle, is disclosed. Conventional systems for power supply to the motor vehicle modules are often excessively used, in particular in utility vehicles when an optimal availability is required. The present method includes measuring parameters characterizing the charge of the accumulator, and transmitting the results of a measurement to a control unit and in generating control signals for the energy sinks or the power sources by a control unit. The method makes it possible to eliminate a frequent cause of a low availability in motor vehicles.
