Regenerative braking is a key feature of hybrid cars that allows them to capture energy that would otherwise be lost during braking and use it to recharge the battery pack. This process significantly improves the overall efficiency of the hybrid system and extends the range of the car in electric-only mode.

When the driver applies the brakes in a hybrid car, the electric motor switches from being a power source to an energy generator. As the car slows down, the electric motor resists the motion of the wheels, converting the car's kinetic energy into electricity. This electricity is then directed to the battery pack, where it is stored for later use.

The amount of energy that can be recovered through regenerative braking depends on several factors, including the speed of the car, the amount of braking force applied, and the efficiency of the electric motor and battery pack. However, studies have shown that regenerative braking can recover up to 70% of the energy that would otherwise be lost during braking.

Regenerative braking also has several other benefits. It reduces wear and tear on the brake pads, as the electric motor handles a significant portion of the braking force. Additionally, regenerative braking helps to keep the battery pack cool, extending its lifespan.

Overall, regenerative braking is a highly effective technology that improves the efficiency, range, and lifespan of hybrid cars. It is a key component of the hybrid powertrain and plays a vital role in reducing fuel consumption and emissions.
