A battery driven car is provided with a transmission system which includes an induction motor fed by way of an inverter from the battery and which drives the wheels through a gear box and a clutch. The gear box enables the induction motor to maintain a sufficient speed to cool itself even when the car is driving at slow speed up a steep hill. The gear box and clutch may be conventional manually operated mechanisms and there is provision for the inverter to be used to charge the battery. |
