What is regenerative braking in Audi e-Tron and how does it work?

I heard that regenerative braking is a feature in the Audi e-Tron. Can you explain how it works and how it helps improve the efficiency of the car?

Regenerative braking is a technology in the Audi e-Tron that recovers energy when the car decelerates or brakes. This energy is then stored in the battery, allowing the car to use it later on for powering the electric motors. This not only improves the efficiency of the car but also increases its range.

By using the electric motors as generators, regenerative braking converts the kinetic energy of the moving car into electrical energy, which is then stored in the battery. This puts less strain on the traditional brakes and helps in preserving their lifespan.

When the driver lifts their foot off the accelerator, the car starts to slow down and the electric motor acts as a generator, converting the kinetic energy of motion into electrical energy. This process also provides some resistance, which mimics the feeling of engine braking in traditional cars.
