What is an i3's regenerative braking system?

I've heard about the regenerative braking system in the BMW i3, but I'm not sure how it works. Can you explain it to me in simple terms?

The regenerative braking system in the BMW i3 converts the kinetic energy from braking into electricity, which is then stored in the car's battery. This helps to extend the driving range of the car.

Think of it like a hybrid between a traditional brake system and a generator. The i3's regenerative braking system captures the energy that would normally be lost during braking and puts it back into the battery.

I've found that using the regenerative braking system on the i3 can help improve braking efficiency and reduce wear on the brake pads. Plus, it's just really cool technology!
