What is Regenerative Braking, and how does it
work?

• Technology is always marching forward when it
  comes to the automotive sector, bringing us
  something new, something better. In fact, cars
  are constantly being designed and developed to
  make them better in different ways. To the
  consumer, a direct benefit of such advancements
  usually means a more fuel-efficient car. Almost
  every new launch provides a more favourable
  answer to that all-important question- kitna
  deti hai? And with better milage often comes
  reduced emissions. One area that many
  manufacturers focus on to make cars more
  efficient is the braking system, especially in
  hybrid and electric vehicles.

Regenerative braking an introduction

• A good solution didnt present itself until
  hybrids (vehicles that use more than one type of
  power) came about, with in-wheel electric motors.
  The same motor that drives the wheel can also be
  used as a generator if it drove the motor. Hybrid
  vehicles already had a high-capacity battery
  present in them, which stored electricity, and
  this was connected to the vehicles motor. All
  that was needed was to allow the motor to send
  electricity back toward the battery when required.

So, how did this lead to regenerative braking?

• When a driver applies the brakes in a vehicle
  with regenerative brakes, the brake pads dont
  immediately rub against the discs as conventional
  brakes do. Instead, the electric motor is engaged
  and uses the wheel to drive the motor and charge
  the battery. This work is usually done by the
  engine under the hood, with petrol or diesel
  power. Traditional brakes are present in hybrid
  vehicles to provide maximum braking power when
  required. However, during most normal braking
  conditions, the electric motor slows down the
  car. This energy is recovered as electric energy
  and used while accelerating again. This is how
  hybrids increase their efficiency by putting to
  good use the energy that would otherwise be
  wasted.

What makes this effective?

• Studies have shown that regenerative braking can
  put 60-70 percent of the energy that goes into
  the brakes to good use. Under standard urban
  driving conditions, this can increase a vehicles
  efficiency by up to 20 percent! It might not
  sound like much at first glance, but lets
  consider a vehicle with a tank capacity of 60
  litres and a fuel efficiency of 10 kmpl.
  Improving efficiency by 20 would give you an
  extra 120km the approximate distance from
  Mumbai to Pune that you can get out of a tank
  of fuel. Of course, it is important to understand
  that this is theoretically speaking. Practically,
  this number could vary depending on various other
  factors.
