A method of controlling electrical energy in a battery-powered vehicle wherein
the vehicle includes a battery and a traction motor is provided. The method includes
electrically coupling an external source of electrical energy to a unitary, integrated
traction motor controller/vehicle battery charge controller positioned on-board
the vehicle, controlling electrical energy flow to a vehicle battery with the unitary,
integrated traction motor controller/vehicle battery charge controller during a
charging period, and controlling electrical energy flow to a vehicle traction motor
that is operable to propel the vehicle with the unitary, integrated traction motor
controller/vehicle battery charge controller during a transport period.
