4QD controllers have been built into a wide range of electric vehicles.
We have provided control systems for the Greenpower IET cars, electric motorbikes and quads, children’s ride on cars and 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 build into a wide variety of vehicles. They can be configured to give smooth progressive acceleration and deceleration, or more dynamic “sporting” performance if required. It is also easy to include an adjustable top speed control.
We also stock all the accessories you need such as throttles, fuses, switches, cables, and even radio control interfaces.
We have a page with tips on how to get the best performance from a Greenpower car.
We’ve recently been asked to assist with a new Greenpower team, we’re keeping a diary of how it goes, what challenges we find, how we plan, and generally to share our experience in the hope that other STEM teachers might find something useful.
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.
