Abstract: - One of the more complicated cases is managing the energy between multiple power sources that are
utilized to power electric cars (EVs). Power management is often carried out following the load requirements of
electric vehicles. By considering the speed and current values of the motor a novel controller is modeled named
as Measurement of parameter-based controller (MPBC) which is used to obtain the smooth transition between
two passive energy sources battery and Supercapacitor (SCap). Further, the proposed MPBC is combined with
fuzzy logic (FLC) and proportional-integral (PI) controllers, forming two different hybrid controllers named
MPBC+FLC and MPBC+PI, utilized to attain proper power management. The main function of traditional
controllers FLC/PI is to generate the pulse signals to the switches present in the bidirectional converters at both
battery and SCap end. On the other hand, the MPBC is utilized to control the pulse signals based on the current
and speed values of the electric motor. Futcher's final MATLAB/Simulink model is built with the proposed
control technique with two hybrid controllers by considering different power-generating conditions of the PV
array, to know the effectiveness of the individual model.

1 Introduction
In the future, renewable energy (RE) sources will
replace conventional energy sources as the primary
means of generating electricity. The use of
conventional energy to produce power is getting
more expensive and hurts the environment due to
large emissions. The main alternative method for
generating energy at a low cost and with little
environmental impact is solar power generation.
Here, sufficient sunlight and irradiance can be used
as inputs to produce solar-powered electricity
without harming the ecosystem. When solar-
powered facilities generate electricity, no
appreciable emissions are emitted into the
atmosphere, indicating that they are environmentally
benign.
These days, the conventional vehicle system is
the only one that is used for a large portion of
transportation. However, depending on the input
energy storage system being used, this traditional
vehicle system-based transport system needs to be
modified. Typically, a conventional transportation
system vehicle runs on petrol or diesel, both of
which have limited supply and produce a significant
amount of exhaust gases when in use. It will be
necessary to convert to an alternative source-based
vehicle to overcome the future limitations of
conventional fuels. To reduce the use of fuel and
diesel, battery-powered electric vehicles are being
developed in place of internal combustion engine-
based vehicles. Typically, to fully charge the energy
source, we must plug the car in to charge the
battery. This element contributes to the local
electricity grid becoming overloaded once more. A
solar-powered power plant is used to create a
separate power-producing station within the car to
reduce the load on the local grid. The local
electricity grid will experience less load as a result.
Renewable energy sources, such as wind, sun, and
biomass, produce energy by absorbing input from a
wealth of resources. For instance, throughout the
day, sunshine is available, making it simple and
independent to meet rising load demands.
According to the results of the standard survey,

conventional technologies are capable of producing
over 70% of the electricity. However, only
renewable resources are used to create a maximum
of 30% of the power. This does not bode well for
the ecosystem. The people in the society should be
educated to maximize the generation of non-
conventional power. From a transportation
perspective, this initiative will increase the use of
EVs and reduce the load on the local grid, [1].
To fulfill the current load demand, new energy
sources are of vital importance because fossil fuels
are running out quickly. Trends in global warming
can also be attributed to the use of fossil fuels, [2].
The most practical solution to this global energy
problem is to use renewable energy sources.
Electricity in the future is anticipated to be primarily
supplied by RE sources, [3], [4].
Investigation of integrated energy storage
management and real-time load evolution at grid-
connected solar electric vehicles. Without any prior
knowledge, a finite time approach with subjective
dynamics of structure inputs has been taken into
consideration. Through the combined optimization
of EV energy ordering quantity, load planning
delays, photovoltaic abundance during periods of
nearby produced renewable energy, and battery
deprivation, the goal is to lower a standard
aggregated system price. The model of one-slot
look-ahead queue stability uses the Lyapunov
optimization method (LOM) to solve the problem as
a result of repeated reformulation and adjustment of
the combined optimization challenge, [5].
The choice of HEVs in transportation networks
is becoming more attractive and important due to
their increased energy consumption. Because of its
eco-friendly design and support for the smart grid
idea, HEVs are experiencing rapid growth. There
are variations in HEV types because of the
differences in ESS across various control
techniques. This makes it harder to choose a suitable
control approach for HEV applications. An
extensive analysis of the key ESS data about HEVs
and feasible optimization topologies based on
various control schemes and vehicle tools, [6].
In this case, the research and analysis involve
transforming the conventional vehicle system into
an autonomous electric vehicle (EV). Reach out to
several ESS devices, such as lead-acid and lithium-
ion (Li-ion) batteries, during this procedure. Three
driving cycles that match the conditions of moving
in have been used in MATLAB/Simulations. These
cycles include a highway with a climb up a
mountain a city, and a highway. All requirements
are based on highways in the Vale do Paraíba
Paulista region, [7], [8].
This study observes the current ESS in EVs and
HEVs, which consists of a battery and a
supercapacitor, to reduce its power density scarcity.
Because there are two ESSs, energy management
needs to be implemented for the HESS. The best
energy management strategy is created by taking
into account Pontryagin's minimal principle, which
instantly distributes the required impulsion power to
the two ESS during vehicle propulsion and also
quickly distributes the regenerative braking energy
to the two ESS, [9].
The main obstacle to optimal energy
management for HESS-based EVs is the
development of supervisory control techniques. A
multi-objective optimization model is developed to
enhance the power exchange between the
supercapacitor and battery. This method handles
problems in an approachable and optimal manner,
[10], [11].
For an EV powered by supercapacitors, a real-time
combined speed control and power flow supervisory
system is developed using a nonlinear control
system approach. Given the relationship between
energy management and HESS sizing, this work
uses a controller design for HESS sizing to find the
ideal HESS size to serve an EV. The controller uses
the HESS selectively to reduce power consumption
and traces the vehicle's set speed with uniformly
exponential stability to decrease battery stress. It is
necessary to use a composite controller by using the
physical source of the vehicle's power requirement.
To determine the use of the controller and HESS
sizing system, a typical urban dynamometer driving
program is used to imitate the driving cycle of a
full-size EV, [12]. Finding 2n−1 stage rearrangeable
Banyan-type networks that are not isomorphic to
one another is the objective of this work. This is
achieved by building substitute networks and
evaluating how well they can be rearranged using
the satisfiability problem. The limited scalability of
this strategy is a drawback because of the huge
number of candidates. To eliminate this issue, it is
shown that the possibilities can be reduced to a
smaller class of networks called pure banyan
networks. This is achieved through the use of
network isomorphism analysis, [13], [14]. This
study intends to evaluate the potential for fuel cell
electric vehicle (FCEV) adoption in Morocco and to
provide insight into fuel cell vehicles by thoroughly
evaluating the Moroccan hydrogen roadmap.
To determine the crucial success factor for
increasing FCEV adoption in the Kingdom, a
SWOT analysis was also carried out, [15], [16].
Based on an analysis of the development status of a
BESS, the study presented application scenarios,

such as the reduction of power output fluctuations,
acceptance of output plans at the side of renewable
energy generation, power grid frequency
adjustment, power flow optimization at the side of
power transmission, and a distributed and mobile
energy storage system at the side of power
distribution, [17], [18], [19], [20].
2 Energy Storage System of Existed
Model
In the current study, a single energy source that
combines solar energy with built-in power
generation was utilized to power the vehicle
independently of the local power grid. With this
setup, the EV can simultaneously charge the battery
and generate power using the solar panel when there
is sunlight. It indicates that the battery will supply
the necessary power to the load for continuous
operation when driving at night.
2.1 Battery Model
The model-based design needs only one or two
iterations of changing and re-verifying the power
system design. The battery is used in the wind
power EV system to store the energy from the grid
supply and also provide the energy to load.

2.2 Super Capacitor Model
The ultracapacitor differs from a typical capacitor in
that it is constructed with a dielectric made of two
plates and can store a certain quantity of energy.
Because UC uses multilayer porous electrodes,
which increase the layer's surface area more than a
regular capacitor does, UC can store 1001000
times more energy than a normal capacitor.

3 Description of Existed Model
Controllers
3.1 Fuzzy Logic Controller (FLC)
The rule-based fuzzifier interface and fuzzifier are
two crucial FLC phases. In addition to the MPBC
controller, another controller included in the
suggested control architecture is the FLC. Three
blocks are essential for producing output signals in
these, which are then utilized to generate the
controlling signal for the converter switches which
is clear from Figure 6. Here, the fuzzification block
receives the change in error and error value. The
fuzzy inference uses this block as its input.

4 Energy Management Strategy with
Proposed Control Technique
This proposes a novel control method, SCap, based
on the electric motor's speed and current values, to
enable the battery to switch between its charging
and discharging stages. Two distinct controllers are
used to implement the suggested control technique:
the typical controllers FLC and PI are employed to
produce the pulse signals that are sent to the
converter. Additionally, such signals are controlled
by the MPBC controller by the electric motor's
speed and current levels. Ultimately, the approach to
fulfill the suggested technique is provided by the
combination of MPBC+PI and MPBC+FLC.
The PV array, battery, SCap, two bidirectional
converters, Boost converter, and the electric motor
shown in Figure 9 comprise the primary circuit of
the suggested model. In this case, the battery is used
to supply the EV with backup power when solar
power generation isn't available, while the SCap is
used to fulfill the peak power requirement. In
contrast, PV arrays are used, depending on the load
placed on the EV, to meet the requirement for EVs
as well as for battery and SCap charging. The two
bidirectional converters' regulated signals are all
based on the proposed control technique, which
consists of two separate controller combinations
known as MPBC plus PI. Based on the actual and
reference voltage levels of the converter, the PI or
FLC controller in this instance generates the pulse
signal to the converter at the battery and SCap end.
However, MPBC operates based on the EM's
current and speed values. This is achieved through
the use of math functions, which produce three
distinct signal types depending on the EM's current
and speed values. To provide the converter at the
battery and SCap ends with regulated pulse signals,
MPBC, PI, and FLC work together to provide the
EV with the appropriate power supply based on the
applied load.

Fig. 9: Main circuit with a Proposed control
technique
Here, three distinct load scenarios are taken into
account, and the controlled signals to the EV are
created accordingly. This will occur by the
suggested controlled technique, which combines
FLC, PI, and MPBC.
The EM's speed and generation-related current
are described by the math functions.
1. The MPBC system creates a signal and sets Y1
to 1 and Y2 and Y3 to 0 when the speed reaches
or exceeds 1500 rpm and the current remains
below 6A. As a result, the supercapacitor
(SCap) and the converter at the battery end
function in a buck mode, making it easier to
charge the battery and SCap using solar energy.
Current flows from the PV array to the load,
SCap (for a short while), and batteries during
this procedure. In addition, the SCap releases an

equivalent amount of energy to support the
motor if it encounters a high load during startup.
2. The MPBC, controller emits a signal when the
speed is between 1400 and 1499 rpm and the
current is between 6 and 8 amps. Y2 is then set
to 1, and Y1 and Y3 are set to 0. In this case, the
supercapacitor (SCap) rapidly supplies the
motor with the required peak power while the
converter at the battery end stays inactive. In
boost mode, the converter at the SCap functions.
There is no current flowing to the battery and
just a brief current flowing to the load from the
PV array and SCap. This suggests that during
this time, the battery does not charge or
discharge.
3. When the EM's speed falls below 1400 rpm and
its current exceeds 8 amps, the MPBC will
produce a signal of one for Y3 and zero for the
other two functions. Because of this, the
converter at the battery and SCap ends operated
in boost mode, allowing current to flow to the
load from the battery, SCap, and PV array. This
shows that, up until the point of charging, the
battery helps the solar array and the SCap under
high-load situations.
4.1 Modes of Operation of the Main Circuit
Model
Depending on the load placed on the EV, the main
circuit operates in one of three modes. The various
modes of operation of the main circuit about the
applied load are depicted in Figure 10, Figure 11
and Figure 12.

The EV's main circuit under typical load
circumstances is seen in Figure 10. In this instance,
the battery can be charged by the PV array in
addition to providing electrical power to the load.
This suggests that controlled pulse signals are
generated to the converter at the battery end to
operate under the buck mode of operation,
depending on the speed and current values of the
electric vehicle. Here, the converter at the PV array's
end operates exclusively in boost mode. This
demonstrates that for mathematical function Y1, the
MPBC controller will be able to generate signals as
1, and for the other two functions, as zero. In
addition, the PV array is supported by the SCap
when the electric motor is operating at maximum
power.

Because of the rated load placed on the EM,
Figure 11 depicts the main circuit power flow from
the PV array to the EV only. In this instance, the
MPBC controller uses the suggested control
approach to regulate the pulse signals produced by
the PI or FLC. As a result, for the remaining math
functions, the MPBC will develop the Y2 function
as 1 and 0. The battery is neither charged nor
discharged when operating in this mode since the
converter at the battery is in the no-working zone. In
addition, the PV array is supported by the SCap
when the electric motor is operating at maximum
power.

The main circuit current flow from the PV array
plus batteries to the load is shown in Figure 12. This
demonstrates the high load that the EV is subjected
to because the battery supports the PV array by
supplying more power to the load as needed.
Furthermore, the PI or FLC-generated pulses are
controlled and supplied to the converter at the
battery end to perform the boost operation only
because the MPBC controller can generate the
signal as 1 for math function Y3 and zero for the
remaining two functions, Y1, Y2. In addition, the
SCap operates in boost mode on the electric motor
and converter to support the PV array at peak power
conditions.
5 Simulation Results and Analysis
Fig. 13: Electric motor speed curve representation
under various load scenarios using PI and FLC
Figure 13 shows the speed curve response of
EM under various loads. Here, three distinct loads
are delivered to the EV at three separate times to
confirm the efficacy of the suggested control
method. When a normal load is applied to the EM
for 0.2 seconds, the motor's speed decreases to about
1500 rpm. When a rated load is applied for 0.4
seconds, the motor's speed decreases to 1400 rpm.
Finally, when a 0.6-second extra rated load is
applied, the motor's speed decreases to even less
than 1400 rpm. While MPBC+FLC took 0.075
seconds, 0.08 seconds, and 0.28 seconds to attain
stability in accordance with the applied loads in
order, MPBC+PI took 0.09 seconds, 0.1 seconds,
and 0.30 seconds. The results from the two
controller outputs showed that MPBC plus FLC
performed better.
Fig. 14: Electric motor's back EMF under various
load scenarios using PI and FLC
The electric motor's back EMF curve under
various load scenarios is displayed in Figure 14.
This will follow the speed curve: at 0.2 seconds, the
curve appears to be decreasing and eventually
achieves the steady state; at 0.4 seconds, the EM's
rated load condition causes the back emf to fall for a
while before reaching the steady state once more.
Eventually, at 0.6 seconds, the motor's overrated
load causes the rear emf value to drop significantly
once more. This process will continue for some time
before returning to its steady-state value, all because
of the suggested control strategy.
Fig. 15: Electric motor current changes related to
load.
Figure 15 shows the electric motor current
under varying load levels. The motor draws a
significant amount of current at first, but after it
reaches a steady state, that value drops to nominal,
meaning the motor is operating without a load.
Different types of loads are applied to the EM at 0.2,
0.4, and 0.6 seconds, which causes the motor to
draw more current in proportion to the imposed
load6A, 8A, and more than 8A.
Fig. 16: Load changes representation on the Electric
Motor
The load curve representation on the EM is
displayed in Figure 16. The motor has a heavy load
before reaching a steady state, therefore EM will
require more current than at regular intervals. Figure
12 makes it clear that the motor reaches a steady
state at 0.1 seconds, at which point no load will
manifest itself in the motor. To assess the

varying loads are applied for 0.2, 0.4, and 0.6
seconds. As a result, the motor's speed reduces and
the current drawn by the EM increases in
combination.

6 Conclusion
This work examines a control mechanism that
modifies the battery and SCap concerning the
motor's speed. Three different math functions that
are independently realized based on the motor's
speed and current values are combined to create the
MPBC. The proposed MPBC controller is combined
with a traditional PI controller and FLC to create a
hybrid controller to fulfil the primary goal of the
project. The MFBC regulated the pulse signals that
corresponded to the motor speed, while the PI
controller FLC generated the switching signals
needed by the converter. Ultimately, a smooth
transition between battery and SCap is achieved
by the demands of electric vehicles by using the
suggested control approach. To carry out the same
function as MFB with PI controller, another hybrid
controller called MPBC with FLC is devised. When
applying the afterload and starting, a comparison
study is carried out. The final section contains a
tabulation and presentation of the findings for all
two techniques. Ultimately, the performance of the
MPBC plus FLC was superior to that of the other
hybrid controller, MPBC+PI.
