TOPIC: ASSESSING EFFICIENCY OF REGENERATIVE BRAKING WITH
ELECTROMAGNETIC BRAKING SYSTEMS IN PHEVs
Introduction
The major electrical braking systems sub-methods include plugging, electric regenerative and
dynamic otherwise rheostat brake. The electric regenerative braking system is associated with
better qualities hence greater popularity as compared to other two.
Importance of Research
The better qualities of electric regenerative braking system has been attributed to energy
regeneration via altering monitoring action into a generator; a process which may be achieved by
other techniques (Faria, Moura, Delgado and De Almeida, 2012). Other benefits include it is not
polluting, cost effective as well does not require frequent maintenance as is case with others
Problem
A lot of energy goes to waste in the transport industry without being recycled with the braking
system forming of leading ways through which energy is lost. The motion of an automobile may
only be controlled by the use of brakes and for the case of most of the conventional vehicles;
there is the conversion of kinetic energy into heat energy as a result of friction that occurs
between the brake pads and the wheels (Kuang et al., 2017). There is no possible mechanism of
storing the heat energy thereby leading to a continuous flow of energy away along the air stream.
Every time a brake is applied to control motion there is a loss or wastage of energy.

LITERATURE REVIEW
Working Principle of Electromagnetic brakes
In case part of copper wire was twisted, around nail thereafter linked with a battery, it will make
an electromagnet. The magnetic field produced in wire, from current, is called "right-hand thumb
run the show". The quality of magnetic field may be altered by changing both wire estimate and
measure of wire (turns). The fields of EM brakes may be made to work at any DC voltage and
torque created by brake will be the equivalent provided right working voltage as well as current
is utilized with right brake. A consistent current power supply is perfect for exact and most
extreme torque from a brake (Moussa, Somers, and Al-Haddad, 2015).
In case a non-directed control supply is utilized magnetic motion will debase as obstruction of
coil rises. Fundamentally, more sizzling coil gets the lower torque will be delivered by around a
normal of 8% for each 20°C. In the event that the temperature is genuinely steady, and there is an
issue of enough administration factor in the outline for minor temperature variance, by
marginally over measuring the brake can make up for debasement. This will allow utilization of
amended power supply that is far more affordable than a consistent current supply (Yang, He,
Zhang and Qin, 2018).
Components of an Electromagnetic Braking System
Disc liner: The covering is component of stopping mechanism that alternates over vehicle's
kinetic energy into heat (Ning et al., 2019). The coating must be suitable for surviving high
temperatures in the absence of intemperate wear or outgassing. Brake linings are manufactured
from typically delicate yet extreme as well as heat-resistant material having high dynamic
