Abstract
An electromobility system for a vehicle comprising a primary sub-system including at least a first battery pack arrangement to power an electric machine for propelling the vehicle, a secondary sub-system being a high voltage sub-system and including at least a second battery pack arrangement to power an auxiliary equipment, and a DC/DC-converter galvanically separating the primary sub-system from the secondary sub-system. The system, in a first state, powers the electric machine by the first battery pack arrangement of the primary sub-system independently of the secondary sub-system, and powers the auxiliary equipment by the second battery pack arrangement in the secondary sub-system independently of the primary sub-system, and in a second state, powers the auxiliary equipment by the second battery pack arrangement of the secondary sub-system and, via the DC/DC-converter, the first battery pack arrangement of the primary sub-system.
