Regenerative Braking in EVs: How It Works
How to Change Regen Settings in the e Vitara First, what is regenerative braking? In a petrol car, braking turns the car's speed into heat at the brake pads, and that energy is simply lost. An EV can do something smarter. When you lift your foot off the accelerator, the electric motor switches roles and works as a generator . It uses the car's momentum to make electricity and sends it back into the battery. That resistance is what slows the car down. Here's what happens in order: You lift your foot off the accelerator, or press the brake lightly. The wheels keep turning the motor, which now generates electricity instead of using it. That electricity flows back into the battery, adding a little range. The effort of generating it slows the car, with no brake pads involved. If you need to stop harder, the normal friction brakes join in automatically. EVs let you choose how strong this regen is. Low regen lets the car coast freely, almost like a petrol car in neutral.
