The invention relates to a motor vehicle (2) comprising a high-voltage on-board network (6) having a high-voltage battery (8), the high-voltage battery (8) having a first energy storage device (12) and a second energy storage device (14). Furthermore, the motor vehicle (2) comprises two low-voltage on-board networks (16, 18) and a first DC-DC converter (28) for converting a high voltage into a low voltage, the first energy storage device (12), the second energy storage device (14) and the two low-voltage networks (16, 18) being connected to one another by means of the first DC-DC converter (28), and the first DC-DC converter (28) being connected to one another by means of the second DC-DC converter (28) in order to adapt the voltage. A second DC voltage converter (30) is connected between the first DC voltage converter (28) and the energy storage device (12, 14), and/or wherein a third DC voltage converter (32) is connected between the first DC voltage converter (28) and the low-voltage network in order to adapt the voltage.
