Abstract
A dual power supply system with first to third system terminals is disclosed. The dual power supply system includes a first battery cell stack interconnected between first and second stack nodes and providing a first operation voltage and a second battery cell stack interconnected between the second stack node and a third stack node and providing a second operation voltage. The dual power supply system further includes a DC/DC converter with first to third converter nodes and configured to convert a voltage of the first or second battery cell stack. Each of the system terminals is connected to the respective stack node or converter node in parallel. The DC/DC converter can provide redundant power supply and active balancing. The application further relates to a vehicle including the above dual power supply system.
