&nderstanding the principle behind regenerative brakingre'uires a brie! look at the syste( it replaces)

 Conventional braking syste(s use friction to counteractthe forward momentum o! a (oving car)

+s the brake pads rub against the wheels, excessive

heat energy is also created)

More energy !ro( the engine is re'uired to replace theenergy lost by braking)

1egenerative braking is a syste( in which theelectric motor that nor(ally drives a hybrid or pure

electric vehicle is essentially operated in reverse2electrically during braking or coasting)

Instead o! consuming  energy to propel a vehicle,the (otor acts as a generator  that charges the onboard

batteries with electrical energy)

 4he acco(panying friction assists the nor(al brakepads in overcoming inertia and helps slow the vehicle)

 4he main utility o! the regenerative brakingsyste(s is that they dramatically increase a vehicles

!uel e9ciency)

  4he syste(s do add cost and complexity to thedrive train, but (any hybrid owners think regenerativebrakes are worth it) In pure electric cars, regenerative

brakes are vital to increasing range and getting the (ostout o! each charge)
