A high voltage traction system for a vehicle includes two independently controllable power sub-systems being a powertrain power sub-system, PPS, and a vehicle power sub-system, VPS. The PPS comprising a plurality of PPS secondary power consumers and a PPS master controller being configured to arbitrate power limits among the PPS secondary power consumers by a first arbitration logic, and the VPS comprising a plurality of VPS secondary power consumers and a VPS master controller being configured to arbitrate power limits among the VPS secondary power consumers by a second arbitration logic, different to the first arbitration logic. A master interface is between the PPS master controller and the VPS master controller enabling communication exchange between the PPS and VPS including system-shared instructions of prioritization of the PPS and VPS secondary power consumers limiting the first arbitration logic and/or the second arbitration logic in a limited state.
