AN ELECTROMOBILITY SYSTEM FOR A VEHICLE

The present invention relates to an electromobility system (15, 115) for a vehicle (1) comprising a primary sub-system (115A) including at least a first battery pack arrangement (130A) configured to power an electric machine (20, 120) for propelling the vehicle, a secondary sub-system (115B) including at least a second battery pack arrangement (130B) configured to power an auxiliary equipment (40 ,140), and a DC/DC-converter (150) arranged and configured to galvanically separate the primary sub-system (115A) from the secondary sub-system (115B). The system is configured to, in a first state, power the electric machine (20, 120) by the first battery pack arrangement (130A) of the primary sub-system (115A) independently of the secondary sub-system (115B), and power the auxiliary equipment (40, 140) by the second battery pack arrangement (130B) in the secondary sub-system (115B) independently of the primary sub-system (115A), and configured to in a second state, power the auxiliary equipment (40 ,140) by the second battery pack arrangement (130B) of the secondary sub-system (115B) and, via the DC/DC-converter (150), the first battery pack arrangement (130A) of the primary sub-system (115A).
