A vehicle includes an inverter connected to an energy store having a variable output voltage and including a first pair of battery partitions. The vehicle includes a controller configured to operate a first set of switches to arrange electrical connections between the first pair such that the variable output voltage is greater than battery voltage of a one of the battery partitions. The operation of switches is responsive to a parameter indicative of speed of an electric machine electrically coupled to the inverter exceeding a first predetermined threshold.
