Look Ma, No Brake! You’ll Drive Electric Cars With One Pedal

You are here: Ultimately, the Tesla Roadster is a sports car and the regen profile will be fine tuned for sports car driving. How does it work?

Covers all aspects of electric vehicle motors and batteries, with a short final chapter on regenerative braking. The harder the pedal is pushed, the more current flows under the direction of a variable resistance controller and the faster the vehicle goes.

If you get about town on a bicycle , it's very obvious that braking is a huge waste of energy. Other personal electric vehicles including electric scooters and skateboards have similar results, usually in the lower single digits.

How Regenerative Braking Works

Emerging technologies for the supercar by Dan McCosh. With the electronic throttle closed and the vehicle still moving, all of its kinetic energy can be captured to both slow the vehicle and recharge its battery.

Another benefit of regenerative braking is extending the life of conventional brake parts such as cables and brake pads. Maintenance costs are lower because barely-used brake pads last for many thousands more miles.

This friction is what turns the car's kinetic energy into heat. An ideal braking system would involve temporarily putting our kinetic energy to one side without throwing it away forever as we do when we hit conventional brakes —a way of storing the energy so we can get it back again in the future.

Indeed, regenerative brakes on bicycles can actually end up using more energy than they save.

There may well have been earlier versions, but not that many: What's less obvious is that it's also a waste of energy.

These can be annoying to maintain and replace, especially since electric bicycles and scooters travel much farther and faster than their non-electric brethren and would otherwise wear out brake pads much quicker.

In electric and hybrid cars , the regenerative brakes charge the main battery pack, effectively extending the vehicle's range between charges. There are a number of subjective decisions we have to make concerning the regen profile.
