Abstract: Traditional cars produce a lot of carbon dioxide (CO2) emissions that are ejected into the atmosphere, causes pollution and greenhouse gases today, electric vehicles (EVs) have received much attention as an alternative to traditional vehicles. The traditional vehicles are powered by internal combustion engines. The electric vehicle is developed because of the advancement in battery technology and motor efficiency. The secondary batteries are the main energy sources of the EV. Thus, energy management is the key factor in EV or Hybrid Electric Vehicles (HEV) design. Moreover, the charge capacity of the battery will influence the endurance of electric vehicles. The main challenge in the HEV is the charging time required for the batteries and insufficiency of charging stations (CS) and therefore charging within existing distribution system infrastructure is problematic. Up to now the HEV‟s CS is in the range of 100 km per charge due to the on-board energy which is needed to be optimized. The second challenge for the EV‟s is their battery capacity which ranges from 8.6KWh to 15.2KWh. The consequent disadvantage is that the charging time for above mentioned size, in a level 1 household charger (120V, 50Hz, 15-20A) is more than 15 hours. Due to these constraints, the vendor (EV charging station supplier) needs a convenient distribution system to cater to customer demand as well as maximize benefits. A special attention must be given to the charging station. In future, the number of electric vehicles will be increasing to a greater extent; these electric vehicles have to re-charge their battery in a place (i.e.) charging station, so there will be a growing need of public accessing charging stations. This will have a significant impact on the power systems like transformers, protection devices etc. With respect to the varying load, it will have an impact on the consumers and vendors due to the traffic at this station, waiting time for charging the vehicles will increase etc. Therefore both the consumer and vendor will get assistance from a communication system which shares useful data regarding the charging station, whether the charging slots are free, rate at which charging is done, cost per unit etc.
In this paper, a new method of integration between PV inverter system with utility grid for electric vehicle charging station based on the extended boost quasi-Z-source (q-ZSI) topology is proposed. The proposed system realizes a bidirectional power flow management between PV sources, energy storage unit and the utility grid. The extended boost q-ZSI is a most efficient topology that provides a single stage conversion for PV systems by providing low ratings for components, reduced number of components used, high input voltage gain, increased voltage boost property , reduced voltage stress across switches and simple control strategies .Its unique capability in single stage conversion with improved voltage gain is used for voltage buck and boost function. A simulation model of the grid connected q-ZSI for electric vehicle charging station has been built in MATLAB/ SIMULINK. The hardware setup was developed and the results are validated.

Design of charging station for electric vehicle batteriesIJAEMSJORNAL
With the increasing requirement in green technologies in transportation, electric vehicles have proven to be the best short-term solution to reduce greenhouse gas emissions. The conventional vehicle drivers are still unwilling in using such a new technology, mainly because of the time duration (4-8 hours) required to charge the electric vehicle batteries with the currently existing Level I and II charging station. For this reason, Level III fast- charging stations capable of reducing the charging duration to 10-15 minutes are being designed and developed. The present thesis focuses on the design of a fast-charging station for electric vehicle, in addition to the electrical grid, two stationary energy storage devices flywheel energy storage and a super capacitor is being used. Power electronic converters used for the interface of the energy sources with the charging stations are designed. The design development also focuses on the energy management that will minimize the battery charging time. For this reason, an algorithm that minimizes durations with its mathematical formulation is required, and its application in fast charging will be illustrated.

Survey on efficient plug in hybrid vehicle chargingeSAT Journals
Abstract
Our future depends upon the renewable energy sources. Since many years vehicles have relied on combustion fuel like oil and
diesel, which will create problem in near future as there are limited reserves of fossil fuels. Hence the most important fact is to
preserve energy. So, plug-in hybrid vehicle (PHEV) is good and effective solution for eco-friendly transportation system.
Therefore, in this paper a plug-in hybrid vehicle approach is presented along with portable solar panel mounted on it to charge
battery. As solar panel is less efficient, a new technique called external light trapping is presented. A 3D printed parabolic
concentrator is used for this purpose. It redirects reflected photons back to solar cells and hence due to multiple reflections its
power conversion efficiency increases. If in any case, battery run out of charge then to charge it mobile chargers (MC) are used.
An android application is developed to support PHEV mobility. It provides full support to driver through its various functions like
monitoring of battery, prediction of range it can travel with current battery state and its location. The mobile server based on
queuing approach determines design parameter for such mobile charging system. An NJN (nearest-job-next) strategy is used to
serve this purpose. In NJN, MC serves next closest PHEV when its current job is done. Moreover, driver can reserve charging slot
based on their availability. So, in short our main purpose is to reduce carbon dioxide emission and mitigate PHEV driver range
anxiety problem.

Design and Implementation of Real Time Charging Optimization for Hybrid Elect...IAES-IJPEDS
Electric vehicle (EV) has gained incredible interest from the past two decade
as one of the hopeful greenhouse gasses solution. The number of Electric
Vehicle (EV) is increasing around the world; hence that making EVs user
friendly becomes more important. The main challenge in usage of EV is the
charging time required for the batteries used in EV. As a consequence, this
subject matter has been researched in many credentials where a wide range
of solutions have been proposed. However those solutions are in nature due
to the complex hardware structure. To provide an unswerving journey
an Android application based charging optimization is proposed.
This application is aimed at giving relevant information about the EV’s
battery state of charge (SOC), accurate location of the EV, booking of the
charging slots using token system and route planner. At emergency
situations, an alternative service is provided by mobile charging stations.
Route planner indicates the temperature by which prediction of reaching the
destination can be done. In addition to that nearest places such as parks,
motels are indicated. The estimated time and distance between the electric
vehicle and the charging station is calculated by the charging station server
according to which the parking lot is allocated. Vehicle to charging station
communication is established for the time estimation of charging. This will
help the EV users to know about charge status and charging station, which
support fast charging method and availability of the station on the go
and also when to charge their EV. The Arduino UNO board has been used
for the hardware part. The hardware results are confirming the conceptual of
the proposed work.
Design and development of smart interoperable electric vehicle supply equipme...IJECEIAES
The transportation industry at present is moving towards electrification and the number of electric vehicles in the market increased with the different policies of the directorate. Consumers, who wish to contribute to green mobility are concerned about the limited availability of charging points due to high manufacturing costs and the interoperability issues related to smart charging. This work proposes an internet of things-based low-cost, interoperable smart electric vehicle supply equipment for deploying in all charging stations. The device hardware is designed to monitor, analyze, and collect consumed energy by the vehicle and transfer this data to a connected network. The pre-defined messages associated with the firmware will help to record this data with a remote management server for further processing. The messages are defined in JavaScript Object Notation (JSON), which helps to overcome the interoperability issue. The device is smart because it can gather energy usage, detect device faults, and be intimate with the controller for a better operational environment. The associated management servers and mobile applications help to operate the smart device remotely and keep track of the usage statics. The developed low-cost, interoperable smart model is most suitable for two and three-wheeler vehicles.
Electric vehicle (EV) charging station powered by the scattered energy sources with DC Nanogrid (NG) provides an option for uninterrupted charging. The NG powered by the renewable energy sources (RES) of photovoltaic (PV) and wind energy. When the excess power produced by the renewable energy stored in the local energy storage unit (ESU) utilized during shortage power from the renewable sources. During the overloading of NG and demand of energy in ESU; the mobile charging station (MCS) provides an uninterrupted charging. The MCS provides an option for battery swapping and vehicle to grid feasibility. The MCS required to monitor the state of charge (SOC) and state of health (SOH) of the battery. Monitoring of SOC and SOH related to the various battery parameters like voltage, current and temperature. A laboratory prototype is developed and tested the practical possibility of EV to NG and Internet of things (IoT) based monitoring of battery parameters.
Energy management strategy for photovoltaic powered hybrid energy storage sys...IJECEIAES
Nowadays, electric vehicles (EVs) using additional energy sources frequently deliver a safe ride without concern about the distance. The energy sources including a battery, an ultra-capacitor (UC), and a photovoltaic (PV) are considered in this research for driving the EV. Vehicles that only use battery-oriented technologies experience problems with charging and quick battery discharge. EVs are used with an ultracapacitor to decrease the quick discharge effects and increase the lifetime of the battery. Furthermore, bidirectional DC-DC converters are a type of power electronics device used to verify the smooth transfer of generated power from energy sources to the motor throughout various stages of the driving cycle. Therefore, this study proposes a perturb and observe (P&O) energy management control technique based on tuna swarm optimization (TSO). The suggested TSOP&O completely uses UC while regulating the battery because it lowers dynamic battery charging and discharging currents. Due to the aforementioned aspect, the suggested TSO-P&O increases battery life and demonstrates a very dependable, long range power source for an electric car. The TSO-P&O technique achieves the EVs by obtaining the maximum speed of 91.93 km/hr. with a quicker settling time of 4,930 ms when compared with the existing zero-fuel zero-emission (ZFZE) method.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Abstract: Traditional cars produce a lot
of carbon dioxide (CO2) emissions that
are ejected into the atmosphere, causes
pollution and greenhouse gases today,
electric vehicles (EVs) have received
much attention as an alternative to
traditional vehicles. The traditional
vehicles are powered by internal
combustion engines. The electric vehicle is
developed because of the advancement in
battery technology and motor efficiency.
The secondary batteries are the main
energy sources of the EV. Thus, energy
management is the key factor in EV or
Hybrid Electric Vehicles (HEV) design.
Moreover, the charge capacity of the
battery will influence the endurance of
electric vehicles. The main challenge in
the HEV is the charging time required for
the batteries and insufficiency of charging
stations (CS) and therefore charging
within existing distribution system
infrastructure is problematic. Up to now
the HEV‟s CS is in the range of 100 km
per charge due to the on-board energy
which is needed to be optimized. The
second challenge for the EV‟s is their
battery capacity which ranges from
8.6KWh to 15.2KWh. The consequent
disadvantage is that the charging time for
above mentioned size, in a level 1
household charger (120V, 50Hz, 15-20A)
is more than 15 hours. Due to these
constraints, the vendor (EV charging
station supplier) needs a convenient
distribution system to cater to customer
demand as well as maximize benefits. A
special attention must be given to the
charging station. In future, the number of
electric vehicles will be increasing to a
greater extent, these electric vehicles have
to re-charge their battery in a place (i.e.)
charging station, so there will be a
growing need of public accessing charging
stations. This will have a significant
impact on the power systems like
transformers, protection devices etc. With
respect to the varying load, it will have an
impact on the consumers and vendors due
to the traffic at these station, waiting time
for charging the vehicles will increase etc.
Therefore both the consumer and vendor
will get assistance from a communication
system which shares useful data
regarding the charging station, whether
the charging slots are free, rate at which
charging is done, cost per unit etc.
1. INTRODUCTION
Smart Charging is an umbrella term that
defines all intelligent functionalities in
EVBox‟s charging stations that optimize the
charging infrastructure by creating and
2. distributing the available power in efficient
and flexible manner. With smart charging,
not only would you avoid unnecessary costs
such as overcapacity fees, but you will also
get the most out of your charging stations in
case of limited power capacity, anytime,
anyplace.
Plug-in electric vehicle (PEV)
commercialization propels an extensive
charging station deployment in a power
distribution system to satisfy fast growing
PEV charging demands.
Considering the power distribution, some
stations deployed at limited capacity feeders
may undergo power overload at peak hours
due to time-varying traffic and PEV
demands. The potential power overload
could lead to severe transformer degradation
or even black-out on the aged power
infrastructure. To avoid power overload
without excessive expenditure on the
infrastructure upgrade, proper energy
compensation at limited capacity station is
highly effective. In this project, we
investigate an energy compensation problem
based on utility-owned mobile vehicular
electric storage (MVES), aiming to mitigate
the overload issues among a group of
charging stations (GCS). In this project,
theory-based GCS transportation model is
developed to facilitate on-road MVES all
location. Then, a two-tier energy
compensation framework is introduced to
efficiently schedule MVESs to minimize the
scheduling cost.
1.1 Need of this concept
Fast Charging stations.
Overload on system gets increase due to
large increase in electric vehicles.
1.2 Objectives of concept
To avoid overload on system.
It avoids manpower as good as possible.
To develop an automatic system.
1.3 Problem Definition
In country like India is very small but
growing therefore at such period the solution
like smart charging station is necessary.
System overloading is the biggest issue in
recent time so it is necessary to balance the
system in between charging station load and
other load.
2. LITERATURE SURVEY:
2.1 What is Two-Tier Energy compensation
framework: -
Fig. Transportation network
The goal of this project is to develop an
energy compensation scheme that uses
MVESs to effectively mitigate the overload
issues timely and cost-efficiently. The
incorporation of GCS operation modeling
and a two-tier energy compensation
framework guarantees a predictable and
timely energy balance among GCS with
minimal cost. To fully utilize the on-road
local resources, an energy compensation
framework is introduced, as shown in Fig. 4.
The framework is operated on two tiers with
central controller on the upper tier and
charging stations on the lower tier. In terms
of fluctuating traffic volumes, the
framework operates hourly to provide
3. analysis and guidance for the next-hour
operation.
A. Upper Tier Operation
The central controller on the upper tier starts
to perform the hourly operation scheme at
time Tclock by requesting the energy
information of each station (e.g. MVES
energy demand of limited capacity station
and MVES charging capacity of resourceful
station). Once the central controller receives
the energy demand information from all
stations, it starts to schedule MVESs
charging and discharging, which consists of
two stages:
Stage 1. MVES Transportation Route
Scheduling
Stage 2. MVES Energy Scheduling
B. Lower tier operation
Limited capacity station qf - once station qf
receives the Information request from the
upper tier, the station dynamics will be
analysed with the traffic data input. Through
the Two-dimensional markov‟s chain
analysis, the next-hour energy Demand
forecast will be obtained and sent to the
upper Tier. Then, upon receiving the
scheduling results from the Upper tier,
station will operate accordingly. In this
project, we study an energy compensation
problem that utilizes MVESs as flexible
energy porters via Vehicle to grid (V2G)
technology. Belonging to the local power
utility company, MVESs are large battery-
capacity PEVs that specialized in being
recharged with additional energy at nearby
available resourceful stations, and then
deliver the energy to overloaded stations in
their peak hours. Since the charging
demands are strongly correlated to the on-
road traffic condition, the service requests
modelling at the charging stations should
consider the stochasticity of PEV traffics. In
terms of power balance at a charging station,
the heterogeneity of arriving PEV State-of-
Charge (SoC) also affects the station
dynamics over time. From the resource
allocation perspective, energy demands need
to be satisfied while minimizing the MVES
scheduling cost and enhancing the time
efficiency of energy transmission. In this
problem, the challenge can be abstracted as
how to allocate the MVES energy
distribution and transportation route among
a GCS to balance the power and minimize
the scheduling cost.
In general, the reviewed works either use the
existing energy in PEVs as additional energy
source or consider PEVs as energy porters to
transmit additional energy. However, PEVs‟
potentials of mitigating PEV charging
overload remain open. The goal of this paper
is to develop an energy compensation
scheme that uses MVESs to effectively
mitigate the overload issues timely and cost-
efficiently. The incorporation of GCS
operation modelling and a two-tier energy
compensation framework guarantees a
predictable and timely energy balance
among GCS with minimal cost.
During the last years, Uppsala municipality
has tightened its climate policies. In 2030,
the goal is that emissions from energy use,
transports and work machinery should be
close to zero. By 2040 the gathered
emissions from the whole municipality shall
be close to zero, corresponding to a decrease
of almost 90% of 1990‟s emissions. By
2050 Uppsala strives to become climate
positive, which means exceeding 100%
decrease in gathered emissions (Lindström,
2015). New smart technologies must be
implemented in order for these goals to be
reached. One proposal is a wider use of
electric vehicles. Today an increasing
number of car manufacturers are offering
EVs in their range of products, leading to a
growing electric vehicle fleet in society.
EVs need to be charged, implying an
additional load for the electric grid. The
current passenger car fleet in Uppsala
municipality consists of 84 137 vehicles
4. (SCB, 2018a). On average, every vehicle is
driven 12000 km per year. If every vehicle
were supposed to be electric and is
consuming 20 kWh per 100 km on average,
the estimated consumption is 0.20 KWh per
year, which makes up about 6.25% of
Uppsala municipalities total yearly
consumption (Länsstyrelsen, 2015).
Research shows that energy usage (unit:
kWh) will not be the problem but the
instantaneous power demand will (unit: kW)
(Nordling, 2016, p. 15-17). Electrical grids
are designed with an upper load limit,
expected to be exceeded with an increasing
number of electric vehicles on the roads.
Instead of raising this limit, one idea to
solve the problem could be to use smart
charging.

compensation framework.
3. Block Diagram Of The System:
Fig: Block diagram of system.
Block Diagram of overall system is shown
in fig 3.1. All components in the working
model are illustrated in above block
diagram. As vehicle enters in gate, IR
sensors mounted at entrance will gets
triggered and starts operating and gives
signal to microcontroller as shown.
Microcontroller controls every operation
performing in the circuit. After the IR
sensor’s signals relay and ULN driver starts
to operate. In that case, by using relay
interlocking mechanism, when feeder1 is
gets overloaded supply automatically
switches on feeder 2. And after obtaining
relay signal the charging station gets on and
vehicle starts charging. After charging
completion signal is again sent to
microcontroller, and thus microcontroller
again provides signal to relay and charging
stops. In parallel the programs in ULN
results in rotation of disk platform in correct
angle and placing vehicle at suitable
charging station.
4. Working of Project Model
Three charging stations of different capacity
are designed near the disk platform. Each
charging station has different capacity i.e.
500W, 1000W, and 1500W for Cars,
Minitrucks and Trucks respectively and they
are named as Charging station 1, Charging
station 2, Charging station 3 respectively. IR
Sensors are connected beside the road at
entrance in order to determine size of
vehicle and by which capacity of battery
should determine.
The size of car is determined by signals of
IR sensors i.e. how many rays are get cut by
vehicle. IR Sensor is a device that emits in
order to sense some aspects of the
surroundings. As size of vehicle get
determined signal is sent to controller and it
5. is given to stepper motor through ULN.
Thus, the vehicle gets placed on disk
platform and disk starts rotating as per given
angles. As per the vehicle size disk rotates
till it comes in front of its suitable charging
station. Charging stations are represented by
batteries in working model.
The LCD will indicate the battery charged in
percentage. After charging completed the
vehicle exits through disk. And system
works similarly for different sizes of
vehicles.
While developing Two-Tier energy
compensation framework the automatic
system is designed to prevent overloading
on feeders. It is such that when one feeder is
gets overloaded while charging two batteries
system automatically switches on feeder 2.

charging facility.
2. It can be used in commercial purpose.
3. It should be used by government by which
will give rise to use of renewable energy
sources.
9. Conclusion
In present days, vehicles are charged
manually the main disadvantage of this is
that one person must be engaged for this. At
the same time during that time he could not
be engage in another task. To overcome
from this, we have decided to prepare the
circuit which will be operated automatically
and charging of vehicle will start by its own
time. This circuit is simple to prepare and
easy to install.
A two-tier energy compensation framework
has been introduced to effectively use
11. MVESs as energy porters at peak hours. It is
concluded that as battery technology
develops, the increasing MVES energy
transmission efficiency can lead to a wider
transmission coverage and more flexible
scheduling. Further, strict station availability
requirement can result in drastic increment
of scheduling cost, leading to a trade-off
between the station availability and
scheduling costs.
Based on the introduced energy
compensation framework, the cost-efficient
MVES scheduling scheme can be applied to
the local power utility company to address
the overload issues without excessive
facility upgrade expenditure. In our future
work, we will propose an incentive
mechanism to encourage private MVESs
participating in the energy compensation
scheduling to fully utilize the on-road
energy sources.
