Abstract: An energy management system (EMS) controls the energy flows in a vehicle by adapting pricing rules. In the EMS the price (Pm, P2, PB1) of the energy is variable dependent of the momentary supply of energy in a global energy system, i.e. the vehicle. Each auxiliary system (GEN, B, C) in the global energy system has in individual price limit, above which the auxiliary system (GEN, B, C) won't purchase any more energy. Some auxiliary systems (B) have variable price limits depending of those auxiliary systems parameters. The auxiliary systems (GEN, B, C) are represented in the EMS by activation agents (CA1, CA2, CAn, BA1, BAn), which have different behaviour depending of what kind of auxiliary system they represent. Said activation agents (CA1, CA2, CAn, BA1, BAn) control the energy flows in the global energy system. In the EMS the energy systems are divided into two categories; energy main system and energy auxiliary systems.
