What is the regenerative braking system in the BMW i4 and how does it work?

I've heard that the BMW i4 has a regenerative braking system. Can you explain what that means and how it works? I'm interested in understanding the technical details.

The regenerative braking system in the BMW i4 takes advantage of the car's electric motor to convert the kinetic energy of the vehicle into electrical energy, which is then stored in the battery for later use. This reduces brake wear and increases the overall efficiency of the car. As for how it works, when the driver steps on the brake pedal, the car's built-in electronics send a signal to the motor to start generating electricity, which is then sent to the battery for storage. This process also helps slow down the car and decreases the need for traditional friction braking.

I'm glad you're interested in the technical aspects of the BMW i4's regenerative braking system. Essentially, when the driver applies the brakes, the electric motor acts as a generator to capture the car's kinetic energy and convert it into electrical energy. This energy is then stored in the battery, allowing for extended driving range. By reducing the reliance on traditional friction brakes, this system also helps preserve their longevity.
