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.
If your driving route has several uphill sections, that strain required to push your car up could reduce its range. Similarly, if the driving route has road sections of poor quality that offer low traction, the efficiency of movement will reduce, and consequently, so will the range. Wet roads have the same issue.

A Comprehensive Overview of Electric Vehicle Charging using Renewable EnergyIAES-IJPEDS
The integration of PV with the electric vehicle (EV) charging system has been on the rise due to several factors, namely continuous reduction in the price of PV modules, rapid growth in EV and concern over the effects of greenhouse gases. Over the years, numerous papers have been published on EV charging using the standard utility (grid) electrical supply; however, there seems to be an absence of a comprehensive overview using PV as one of the components for the charger. With the growing interest in this topic, it is timely to review, summarize and update all the related works on PV charging, and to present it as a single reference. For the benefit of a wider audience, the paper also includes the bries description on EV charging stations, background of EV, as well as a brief description of PV systems. Some of the main features of battery management system (BMS) for EV battery are also presented. It is envisaged that the information gathered in this paper will be a valuable one–stop source of information for researchers working in this topic.
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.
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.
DATA DRIVEN ANALYSIS OF ENERGY MANAGEMENT IN ELECTRIC VEHICLESvivatechijri
Inevitably, there has been a concerted policy push at the national level to promote electric vehicles. In electric vehicles, the progress stands and falls with the performance of the battery. Lithium-ion batteries are considered in this research project, as they are the most crucial component in the electric vehicle power system and require accurate monitoring and control. Proper battery optimization in electric vehicles requires a meticulous energy management system. The energy management system is bound for estimating the battery state of charge, state of health, various distinct factors in the system, and subsystems in real-time. The state of charge estimation accounts for the prevention of over-charge and over-discharge of batteries and provides cell balancing. Traditional SOC estimation approaches, such as open-circuit voltage (OCV) measurement and current integration (coulomb counting), are relatively accurate in some cases. However, estimating the SOC for Li-ion chemistries requires a modified approach. This project presents the Kalman filtering algorithm for the state of charge estimation that provides precise results for a fair computational effort.
Hydrogen Fuel Cell Electric Vehicles Future of Sustainable Mobilityijtsrd
Electric vehicles or referred to as EVs, are the future of mobility. They aid in reducing vehicle pollution and pave the way to a cleaner and greener environment. However, technology is something that gets advanced with each passing day. The next personification of electric cars is the hydrogen fuel cell vehicle. They have a close resemblance to EVs, but the working principle is entirely different. Like all electric vehicles, fuel cell electric vehicles FCEVs use electricity to power an electric motor. In contrast to other electric vehicles, FCEVs produce electricity using a fuel cell powered by hydrogen, rather than drawing electricity from a battery.

Editor's Notes
We left part 1 of this EVU mini-course by asking the question:
>> Why can’t we build higher capacity, cheaper EV batteries?
The answer is that we can, but the technology is complex.
>>So, what’s the battery capacity and cost challenge?
>> Inside an EV, there is a limited space and a limited geometry in which we can place a battery.
Therefore, we need to design and build batteries with higher energy density per cubic cm to overcome the geometric constraints.
>> But there are also weight constraints. Every additional pound that the electric motor must move forward reduces the EV range for a given battery
>> Finally, there are other technological metrics.
Each of these must be considered as new battery chemistries are developed.
The metrics can be represented using a radar diagram (shown on the right of your screen) that provides what we’ll call a “footprint” for the battery.
Let’s consider each of the metrics separately.
The first technological metric we’ll consider for EV batteries is specific energy.
>> Specific energy is the capacity of the battery—the amount of energy it can deliver until it is depleted.
>> Specific energy is measured in energy output per unit weight (e.g., kWh/kg)
Because the Ev competes directly with ICE vehicles,
>> the ultimate challenge is to achieve the specific energy of Gasoline. Gas delivers 13 kWh per kilogram—
over 100 times more energy density than a Li-ion battery.
It’s highly unlikely that batteries will every achieve the specific energy of gasoline, so for now,
>> the goal is to double or even triple the specific energy of EV batteries
The second technological metric is cost.
Battery cost is the primary reason why current EV buyers pay a price premium for EVs.
>> Cost is a function of:
>> the manufacturing costs for battery cells—the individual batteries that are the building blocks for an EV battery
>> the costs of the battery management system and its related subsystems
>> thermal management system that controls battery temperature
>> safety system that is design to recognize any safety problems and protect the integrity of the battery
>> power management system that controls power flow into and out of the EV battery
>> support hardware that incorporates power electronics, wiring harnesses, pack housing
The chart on the right of the screen provides a typical cost breakdown for an EV battery pack. The battery cells represent 50% of overall battery cost, with other electronics, control systems, management systems and business costs representing the other half.
The third technological metric is battery life span.
Every battery degrades as the number of charging cycles grows.
A battery’s life span is:
>>the number of charging cycles that a battery can accommodate before losing 20+ percent of its capacity
>> It’s a function of:
>> temperature—battery performance and life span degrades at temps above 86 deg F
>> charge protocol—whether charging regularly occurs in a fully depleted battery or one that has significant capacity left,
>> and the degree to which the battery capacity is charged to its limit
Today, battery costs are high. Therefore, life span is a major concern because the cost of battery replacement for an EV is significant.
The fourth technological metric is performance.
An EV battery must provide the power needed, when needed without fail.
>> Performance is a somewhat vague term that addresses the ability of a battery to meet it power and recharging requirements, regardless of its environment
This includes:
>> the ability to operate effectively in various climates;
>>for example, extreme temperatures can impact battery capacity by 20 - 30%
In fairness, it should be noted that extreme temperatures also effect the range of ICE vehicles, sometimes significantly.
>>Finally, performance also alludes to the time required to achieve a full charge with higher performing battery taking less time for a full charge.
The fifth technological metric is safety, normally considered in the context of battery fires or other reactions that might endanger the driver or passengers.
There are well over 150,000 vehicle fires in the U.S every year with approximately 350 deaths and almost 2000 serious injuries.
99.99 percent occur in ICE vehicles.
>> To date, there have been few verified safety issues with EV batteries and/or EVs in general,
>> BUT the media seems obsessed with any fire that might be even remotely related to the EV battery. The most celebrated cases occurred when three different Tesla Model S vehicles has fires during 2013, its first full year on the market. The media reported these events as if car fires were rare. They are not.
Here’s a comment on these incidents from MIT Technology Review: “In two cases, the cars ran over large metal objects at highway speed; the third car hit a concrete wall. No one was hurt: a warning system allowed the drivers to pull the car over and get out before smoke started coming from the battery pack, and the design of the battery pack slowed the spread of the fire, which never made it into the passenger compartments.”
However, public perception is reality, and for that reason,
>> a sophisticated safety subsystem and robust battery enclosures are mandatory elements of the battery management system.
The safety subsystem
>> ensures no thermal overload
>> controls run-away charging or operation
The last technological metric is Specific power, sometimes referred to as the power to weight ratio.
Specific power is
>> the amount of power delivered per kilogram for any object that produces power as output
For ICE vehicles, specific power often refers to the power produced by an ICE vs. the weight of the engine.
For EVs, it refers to the power produced by the battery vs. the weight of the battery.
>> batteries with high specific power can discharge electricity rapidly in powerful bursts
With the observable benefit that
>> EV batteries with high specific power allow their vehicle to accelerate rapidly
>>The design trade-off is that high specific power increases the cost per kWh of storage capacity
The Boston Consulting Group used the six battery metrics we just discussed to create footprints for 5 different lithium Ion chemistries.
A quick scan of the footprints indicates that Lithium Titanate batteries, based on advanced nanotech,
offers low cost and reasonable specific power, a very long life span,
and good performance (particularly their ability to recharge quickly),
but relatively poor specific energy, meaning that battery capacity would suffer.
A detailed discussion of the footprint for each of these battery chemistries is beyond the scope of this mini-course, but the interested reader should use the link provided to learn more.
