Abstract
An energy exchanger for a battery driven vehicle comprising two rotatable electrical machines connected on the same shaft, one of high voltage, the other of low voltage. The electrical machines can each be operated in generator or motor modes and the machines are electrically connected together to the battery on a vehicle via an electrical control circuit such that the machines exchange energy between themselves and the battery, both to drive the vehicle by battery drain and to recharge the battery when the vehicle is decelerating. The battery can be recharged from an external power supply via the machines which then operate in generator mode.
