Presentation on Electric Vehicle By Vivek Atalkar.
An electric vehicle, or EV, is a type of vehicle that uses electricity as its main source of power instead of traditional fuels like gasoline or diesel. EVs are powered by electric motors that run on rechargeable batteries, which can be charged by plugging the vehicle into an electrical outlet or charging station.
There are two types of electric vehicles: battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). BEVs are fully electric vehicles that run entirely on battery power and have no backup gasoline engine. PHEVs have both an electric motor and a gasoline engine, and can run on either electricity or gasoline.
Electric vehicles offer several benefits over traditional gasoline-powered vehicles. They produce zero tailpipe emissions, which means they don't contribute to air pollution. They also tend to be more energy-efficient and cost less to operate over the long-term. Additionally, electric vehicles are generally quieter and provide smoother acceleration compared to gasoline-powered vehicles.
One of the main challenges of electric vehicles is their limited range compared to gasoline-powered vehicles, although this is improving as battery technology advances. Another challenge is the availability of charging infrastructure, which is still developing in many parts of the world.
Overall, electric vehicles are an important part of the transition to a more sustainable and environmentally-friendly transportation system.
electric vehicle is very important for the glob...because it has lot's of advantages ...only one disadvantages is that it is requrie more time to charge..its has mainly 3 type of electric vehicle .

plug in hybrid electrical vehicals seminar ppt by MD NAWAZMD NAWAZ
A 'gasoline-electric hybrid car' or 'Plug in hybrid electric vehicle' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. It has great advantages over the previously used gasoline engine that drives the power from gasoline only. It also is a major source of air pollution. The objective is to design and fabricate a two wheeler hybrid electric vehicle powered by both battery and gasoline. The combination of both the power makes the vehicle dynamic in nature. It provides its owner with advantages in fuel economy and environmental impact over conventional automobiles. Hybrid electric vehicles combine an electric motor, battery and power system with an internal combustion engine to achieve better fuel economy and reduce toxic emissions.
In HEV, the battery alone provides power for low-speed driving conditions where internal combustion engines are least efficient. In accelerating, long highways, or hill climbing the electric motor provides additional power to assist the engine. This allows a smaller, more efficient engine to be used. Besides it also utilizes the concept of regenerative braking for optimized utilization of energy. Energy dissipated during braking in HEV is used in charging battery. Thus the vehicle is best suited for the growing urban areas with high traffic. Initially the designing of the vehicle in CAD, simulations of inverter and other models are done. Equipment and their cost analysis are done. It deals with the fabrication of the vehicle. This includes assembly of IC Engine and its components. The next phase consists of implementing the electric power drive and designing the controllers. The final stage would consist of increasing the efficiency of the vehicle in economic ways.

Novel technique for hybrid electric vehicle presentation 1Manish Sadhu
Problem Summary:
Higher demand of current results an important heating of the battery, this heating will generate several consequences, firstly a reduction of lifespan of the battery and secondly a significant loss of capacity. Supercapacitors are used in series with a power battery to provide power requirement in transient state. An energy battery is placed in parallel, this battery gives the power in steady state.
Detailed Description Problem:
Modern batteries (e.g., Li-ion batteries) provide high discharge efficiency, but the rate capacity effect in these batteries drastically decreases the discharge efficiency as the load current increases. Electric double layer capacitors, or simply supercapacitors, have extremely low internal resistance, and a battery-supercapacitor hybrid may mitigate the rate capacity effect for high pulsed discharging current. However, a hybrid architecture comprising a simple parallel connection does not perform well when the supercapacitor capacity is small, which is a typical situation because of the low energy density and high cost of supercapacitors. A new battery-supercapacitor hybrid system that employs a constant-current charger. The constant current charger isolates the battery from supercapacitor to improve the end-to-end efficiency for energy from the battery to the load while accounting for the rate capacity effect of Li-ion batteries and the conversion efficiencies of the converters.
Excepted Outcome:
The supercapacitor will take an important part for the improvement of the energetic efficiency of the embarked systems and in the reduction of batteries replacement. Supercapacitor increases the performance motor at accelerated and reaccelerated mode. Also increases the life span of the battery. Indeed the supercapacitors will not be used as source of pure energy, because of their weak energy mass, but rather of complement to the battery, providing the strong demands of power. The supercapacitor solution as source of power is clearly interesting; however the cost of the kilowatt per hour remains higher than for the batteries lead-acid (approximately 30 times more) but with a weight and volume weaker.
Other Description:
Supercapacitors are widely used for energy storage in various applications. Specifically, supercapacitors are gaining more attention as energy storage elements for renewable energy sources which tend to have a high charge-discharge cycle frequency, and demand high cycle efficiency and good
Depth-of-discharge(DOD) properties. There are several related battery-supercapacitor hybrid architectures in the literature on hybrid electric vehicles (HEVs). A bidirectional converter-based approach is introduced for the regenerative brake-equipped HEVs. A DC bus-based architecture for the battery-supercapacitor hybrid system is described in. However, it is difficult to directly apply these architectures to portable applications because they are designed for the HEV which involves high-power op
Architecture of electric vehicles.pptxHushedAhmad1
The architecture of electric vehicles (EVs) encompasses the intricate integration of components that enable their electric propulsion. This includes the arrangement of the electric motor, power electronics, and energy storage system (usually lithium-ion batteries) within the vehicle's frame. The architecture also involves control systems, thermal management, and regenerative braking mechanisms to optimize efficiency. This thoughtfully designed structure contributes to EVs' environmental benefits and provides a foundation for continuous innovation in the realm of sustainable transportation.
EV, Problems associated with it and different Solutions.pptxLavJivani
this PPT contains history of the EV, components of the modern EV, different problems associated with it and different solutions to improve quality and user friendliness of EV.
different problems like lack of standardization, range anxiety, cost of the vehicle, performance of the vehicle, different environmental issues, are there in modern EV. different solutions like aluminum air battery, battery swapping stations, hybrid battery of li ion battery and al air battery.
The electric car is basically a machine that operates on Electric Car battery. Instead of the conventional gasoline engine, you have components powered by electrical energy. The car moves by the power supplied by this electric energy.
The single most important component in the electric car is the battery. It provides the motive force aside the powering of electrical components like the wiper, headlamps and horn.
We take a look at the battery system of the electric car which looks and works in a much different way from that of conventional vehicles.

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.
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.

2. CONTENTS
• Introduction
• Historical background
• Types of electric vehicles
• Types of battery
• Power electronics controller
• Electric motors of EV’s
• Benefits
• Drawbacks
• Conclusion
3. INTRODUCTION
• The large number of automobiles in use around the world has caused and continues to
cause serious problems of environment and human life. Air pollution, global warming,
and the rapid depletion of the earth’s petroleum resources are now serious problems.
• Evolution of E-mobility.
• Electric motors give electric cars instant torque, creating strong and smooth acceleration.
5. WHAT IS AN ELECTRIC CAR ?
• Electric Car propelled by Electric Motors and uses electrical energy sored in batteries.
• Unlike vehicles with combustion engines, electric vehicles do not produce exhaust gases
during operation. This alone makes electric vehicles more environmentally friendly than
vehicles with conventional technology.
• However, the electrical energy for charging the vehicle does have to be produced from
renewable sources, e.g. from wind, solar, hydroelectric or biogas power plants. By
combining different drive types, the overall efficiency of the vehicle can be improved and
fuel consumption can be reduced.
9. HISTORICAL BACKGROUND
• Thomas Parker in 1888 invented the world’s first electric car.
• The energy crisis of 1970s and 1980s brought a renewed interest in electric vehicles.
• Electric cars were prevalent in early 21th century, when electricity was preferred in
automobile propulsion.
• Further the global economic recession of late 2000s called to abandon the fuel inefficient
SUVs, in favor of small cars, hybrid cars and electric cars.
10. HOW ELECTRIC CAR BEGAN TO LOSE ITS
POSITION INTHE AUTOMOBILE MARKET
12. HOW DOES IT WORK?
• When the pedal is pushed;
1. The controller gathers energy from the battery,
2. Controller delivers the appropriate amount of
electrical energy to the motor.
3. Electric energy transforms to mechanical energy.
4. Wheels turn, vehicle moves.
14. BATTERY ELECTRIC VEHICLE (BEV)
• A BEV runs entirely on a battery and electric drive train, without an internal combustion
engine. It is powered by electricity from an external source, usually the public power grid.
This electricity is stored in onboard batteries that turn the vehicle’s wheels using one or
more electric motors.
15.
16.
17. HYBRID ELECTRIC VEHICLE (HEV)
• An HEV has two complementary drive systems - a gasoline engine and fuel tank, and an
electric motor, battery and controls. The engine and the motor can simultaneously turn
the transmission, which powers the wheels.
• Where the HEV differs from the above two types of electric vehicles (BEV and PHEV) is
that HEVs cannot be recharged from the power grid.
• Their energy comes entirely from gasoline and regenerative braking.
• HEVs have an advantage over BEVs because consumers are already comfortable with
gas- or diesel-fuelled vehicles.
20. PLUG IN HYBRID ELECTRIC VEHICLE
• PHEVs can recharge the battery through both regenerative braking and ‘plugging-in’ to an
external electrical charging outlet.
25. BATTERY
• One of the key elements of any electric vehicle is its battery.
• Energy density is a measure of how much energy a battery can hold. The higher the
energy density, the longer it will last before needing to be recharged.
• Power is the rate at which energy is used. Power density is a measure of how much power
a battery can deliver on demand; that is, how quickly it can release its energy (and
conversely, how quickly it can be recharged).
26. TYPES OF BATTERY
• Lead Acid
• Nickel-Metal-Hydride
• Lithium-ion (Li-ion)
• Lithium Polymer (Li-poly)
• Lithium Iron Phosphate (LFP)
27. SOME IMPORTANT BATTERY TERMS
• Capacity – The total Amp-hours (Amp-hr) available when the battery is discharged at a
specific current (specified as a C-rate) from 100% SOC.
• State of charge (SOC) – Battery capacity, expressed as a percentage of maximum
capacity.
• Depth of Discharge (DOD) – The percentage of battery capacity that has been
discharged.
• Energy – The total Watt-hours (Wh) available when the battery is discharged at a specific
current (specified as a C-rate) from 100% SOC.
28. POWER ELECTRONICS CONTROLLER:
• This unit manages the flow of electrical energy delivered by the traction battery,
controlling the speed of the electric traction motor and the torque it produces.
• DC to DC converter is a category of power converters and it is an electric circuit which
converts a source of direct current (DC) from one voltage level to another.
• DC/DC converters can be designed to transfer power in only one direction, from the input
to the output. However, almost all DC/DC converter topologies can be made bi-
directional. A bi-directional converter can move power in either direction, which is useful
in applications requiring regenerative braking.
29. NON-ISOLATED CONVERTERS
• There are five main types of converter in this non-isolated group, usually called the buck,
boost, buck-boost, Cuk and charge-pump converters.
30. ISOLATED CONVERTER
• There are many types of converters in this group such as Half-Bridge, Full-Bridge, Fly-
back, Forward and Push-Pull DC/DC converters.
32. MOTORS USED IN E-VECHILE
• Brushless DC Motor
• Permanent Magnet Synchronous Motor (PMSM)
• AC Induction Motors
• Switched Reluctance Motors (SRM)
33. BRUSHLESS DC MOTORS
• It is similar to DC motors with Permanent Magnets.
• It is called brushless because it does not have the commutator and brush arrangement. The
commutation is done electronically in this motor because of this BLDC motors are
maintenance free.
• BLDC motors have traction characteristics like high starting torque, high efficiency
around 95-98%, etc.
• BLDC motors are suitable for high power density design approach.
34. OUT-RUNNER TYPE BLDC MOTOR:
• In this type, the rotor of the motor is present outside and the stator is present inside. It is
also called as Hub motors because the wheel is directly connected to the exterior rotor.
This type of motors does not require external gear system.
35. IN-RUNNER TYPE BLDC MOTOR:
• In this type, the rotor of the motor is present inside and the stator is outside like
conventional motors. These motor require an external transmission system to transfer the
power to the wheels, because of this the out-runner configuration is little bulky when
compared to the in-runner configuration.
36. BENEFITS
• Drive motors run quieter than internal-combustion engines. The noise emissions from
electric vehicles is very low. At high speeds, the rolling noise from the tires is the loudest
sound.
• Electric vehicles produce no harmful emissions or greenhouse gases while driving. If the
high-voltage battery is charged from renewable energy sources, an electric vehicle can
be run CO2-free.
• In the near future, if particularly badly congested town centers are turned into zero-
emissions zones, we will only be able to drive through them with high-voltage vehicles.
37. BENEFITS
• The electric drive motor is very robust and requires little maintenance. It is only subject to
minor mechanical wear.
• Electric drive motors have excellent torque and output characteristics. They develop
maximum torque from standstill. This allows an electric vehicle to accelerate considerably
faster than a vehicle with an internal combustion engine producing the same output.
38. DRAWBACKS
• Electric vehicles have a limited range due to battery size and construction.
• Charging a high voltage battery can take a long time, depending on the battery charge
and power source.
• The network of electric charging stations is sparse.
• If the destination is beyond the range of the electric vehicle, the driver will need to plan
the journey.
• “Where can I charge my electric vehicle on the road?”
39. CONCLUSION
• With this, we come to following facts that number of expected vehicles doubling on the
roads in the near future the need for this alternative energy is very evident and has
promising returns.
• Important to produce vehicles that do less, have a longer range, and use less energy.
Lower our toxic emissions and localize green house effects.
• Increase the overall energy efficiency of cars.
