How does regenerative braking work in BMW iVision?

I've heard that the BMW iVision has regenerative braking, but I don't fully understand how it works. Can you explain the technology behind it?

Regenerative braking in the BMW iVision works by capturing and storing energy that would otherwise be lost during braking. Instead of using traditional brakes, the car uses the electric motor to slow down and convert the kinetic energy into electrical energy. This energy is then stored in the battery for later use.

Think of it like a hybrid between a generator and a traditional brake system. When you press on the brake pedal, the motor switches into generator mode and converts the energy from the moving vehicle into electrical energy. This not only helps to recharge the battery, but also reduces wear and tear on the brakes, making them last longer.
