ELECTRIC VEHICLES

摘要

An electric vehicle, for example a scooter, is described. This has a step-through chassis space (24) between the seat (26) and the handlebars (28). Batteries (12) are located beneath the footplate (30). Arrangements are described in which an electric motor provides drive in place of an internal combustion engine. A pancake motor is preferred as the drive motor choice. This may have a sensor to sense the relative positions of magnets and energise electromagnets in accordance with speed and/or torque required. There may be a clutch in the drive chain. An electronic control system is also described for receiving various inputs and providing various outputs to maximise the efficiency of the electric vehicle.
