4QD controllers are built into a very wide range of electric vehicles.

We have provided control systems for the Greenpower IET cars,  electric motorbikes and quads, children’s cars, go-karts, electric wheel-barrows, model tanks, electric bikes, and even electric surf boards.

Our controllers have a long list of features that make them easy to incorporate into a wide variety of vehicle applications, there is a table that shows all the features across all models on this page.

All 4QD controllers can be configured to give smooth progressive acceleration and deceleration, or more dynamic “sporting” performance if required. It is also easy to implement an adjustable top speed control.

We have a page in our knowledgebase dedicated to getting the best performance from a Greenpower car.

If you are looking for inspiration for an electric vehicle then Built for Fun EVs have some really nice plans.

Although not really an electric vehicle application, we have seen number of automotive power steering pumps converted to electric drive with a controller allowing fine adjustment of the assistance level. This has proved successful in racing cars where it can increase the available horsepower by removing the pump load on the engine, and also reduce driver fatigue.
