A voltage supply unit, provided with a first output adapted to supply a first voltage to a first load and provided with a second output adapted to supply a second voltage to a second load, where the voltage supply unit comprises a first battery stack, a second battery stack and an electronic control unit, wherein the electronic control unit is adapted to regulate the energy state of the first battery stack to a first energy state, and to regulate the energy state of the second battery stack to a second energy state, where the first energy state differs from the second energy state. The advantage of the invention is that the power characteristics of the voltage supply unit can be optimized by allowing the energy states of the first and the second battery stacks to differ.
