ABSTRACT
Regenerative braking systems (RBS) are an effective method of
recovering the energy released and at the same time reducing the
exhaust and brake emissions of vehicles. This method is based on the
principle of converting the kinetic energy created by the mechanical
energy of the motor into electrical energy. The converted electrical
energy is stored in the battery for later use. These systems provide
economic benefits via fuel savings and prevention of material loss.
Their use also contributes to a clean environment and renewable
energy sources, which are among the most important issues on the
global agenda. It is clear that more comprehensive studies should be
carried out in this area.
INTRO TO REGENERATIVE BRAKING
The first law of thermodynamics
states that energy can neither be
created nor destroyed, only
altered in form.
Regenerative braking systems
(RBSs) are a type of kinetic energy
recovery system that transfers the
kinetic energy of an object in
motion into potential or stored
energy to slow the vehicle down,
and as a result increases fuel
efficiency. These systems are also
called kinetic energy recovery
systems.
NEED OF REGENERATIVE BRAKING
Regenerative braking is a unique
technique that is used in EVs to
capture energy that the vehicle
has due to its motion or, in other
words, its kinetic energy that
would have been wasted when
the vehicle decelerates or comes
to a standstill while braking.
WORKING OF REGENERATIVE BRAKING
PRINCIPLES OF REGENERATIVE BRAKING
Energy Conversion :
Regenerative braking converts the kinetic energy of a moving vehicle into electrical energy, which can be
stored for later use.
Motor as Generator :
The electric motor in an EV acts as a generator during braking, producing electricity that charges the vehicle's
battery.
Increased Efficiency :
By recapturing energy that would otherwise be lost as heat, regenerative braking Improves the overall energy
efficiency of an electric vehicle.
Battery Charging :
The generated electrical energy is used to charge the vehicle's battery, extending the driving range between
charges.
FACTORS AFFECTING REGENERATIVE BRAKING
EFFICIENCY
Vehicle Weight:
The heavier the vehicle, the greater the kinetic energy that can be harvested during braking, improving
regenerative efficiency.
Battery State of Charge:
The battery's state of charge significantly impacts the amount of energy that can be recaptured, with
higher states of charge reducing regenerative braking capacity.
Driving Conditions:
Road grade, traffic patterns, and driver behavior all influence the frequency and intensity of braking
events, directly affecting regenerative energy recovery.
Thermal Management:
Effective thermal management of the electric motor and battery is crucial to maintain optimum
regenerative braking efficiency and prevent performance degradation.
PROS & CONS OF REGENERATIVE BRAKING
SYSTEM
ENERGY RECOVERY THROUGH REGENERATIVE
BRAKING
Nearly all of the kinetic energy propelling your car forward is lost as
heat when you apply the brakes. That's a lot of wasted energy!
Regenerative braking solves this problem by recapturing upwards of
70% of the kinetic energy that would otherwise be lost during
braking.
