Abstract
A propulsion system for an electric vehicle, the system comprising a high voltage battery unit having a first high voltage battery connected in series with a second high voltage battery such that a nominal operating voltage of the high voltage battery unit is the sum of a voltage of the first high voltage battery and a voltage of the second high voltage battery; at least one power inverter arranged to connect the high voltage battery unit and the first high voltage battery to at least one electrical machine; wherein the power inverter is configured to distribute energy generated by the at least one electrical machine to the first and second high voltage battery to balance a state of charge of the first and second high voltage battery.
