Abstract

An energy management system for an agricultural vehicle arrangement includes an electric power supply unit for the supply of a large number of electrical consumers with electric power, and a consumption monitoring unit for the determination of a total energy demand dependent on an actual operating state of the electrical consumers. The consumption monitoring unit undertakes an estimate of the electric power supply available from the electric power supply unit and compares it to the determined total electric power demand in order to reduce the electric power supply to the electrical consumers as a function of assigned supply priorities when the available electric power supply is exceeded by the determined total energy demand. The consumption monitoring unit undertakes a dynamic adaptation of the supply priorities as a function of a changing cooling demand of a vehicle unit that is cooled by means of at least one of the electrical consumers.
