摘要： The present invention refers to a dual power supply system (100) with a first system terminal (101), a second system terminal (102), and a third system terminal (103). The dual power supply system further comprises a first battery cell stack (14) that is interconnected between a first stack node (11) and a second stack node (12) and provide a first operation voltage and a second battery cell stack (15) that is interconnected between the second stack node (12) and a third stack node (13) and provides a second operation voltage. The dual power supply system further comprises a DC/DC converter (20) with a first converter node (21), a second converter node (22) and a third converter node (23) that is configured for converting a voltage of the first battery cell stack (14) or the second battery cell stack (15). Each of the system terminals (101,102,103) is connected to the respective stack node (11,12,13) and the respective converter node (21,22,23) in parallel. In the dual power supply system of the invention, the DC/DC (20) can provide redundant power supply and active balancing. The invention further relates to a vehicle (200) with such dual power supply system (100).
