The document summarizes an experimental analysis of converting a 1400 cc diesel engine car into a hybrid electric vehicle using BLDC hub motors. Key findings include:
1) The conversion achieved fuel savings of 45-61% compared to the conventional vehicle through the use of lower power hub motors and a separate battery pack for the electric motors.
2) Performance of the vehicle was retained after conversion, with no changes needed to the existing electrical or hydraulic brake systems.
3) The proposed conversion method could be easily implemented on many existing small cars with front-wheel drive to reduce emissions and fuel consumption cost-effectively.
Today transportation sector has facing many problems with conventional vehicles like petroleum and diesel vehicles which release most of the pollutants like CO2 and nitrogen oxide emissions which ultimately have an effect on human health. so to decrease this problem there is the invention of electrical vehicles but to fixed battery EVS the owner of the vehicle should wait for long hours to charge one vehicle and if the vehicle stops in any remote areas then it is difficult to charge the battery. So to reduce this problem and to increase electrical vehicle using the solution is to use autonomous battery swapping stations and producing mobile van technology for charging the vehicle in remote areas this idea ultimately increases EV adoption in the world which leads to having good human health.

Have you pulled your car up to the gas/petrol pump lately and been shocked by the high
price of gasoline? As the pump clicked past Rs1400 or 1500, maybe you thought about
trading in that SUV for something that gets better mileage. Or maybe you are worried
that your car is contributing to the greenhouse effect. Or maybe you just want to have
the coolest car on the block. Currently, there is a solution for all this problems, it's the
hybrid electric vehicle.
The vehicle is lighter and roomier than a purely electric vehicle, because there is less
need to carry as many heavy batteries. The internal combustion engine in hybrid-electric
is much smaller and lighter and more efficient than the engine in a conventional vehicle.
In fact, most automobile manufacturers have announced plans to manufacture their own
hybrid versions. Hybrid electric vehicles are all around us. Most of the locomotives we
see pulling trains are diesel-electric hybrids. Cities like Seattle have diesel-electric
buses -- these can draw electric power from overhead wires or run on diesel when they
are away from the wires. Giant mining trucks are often diesel-electric hybrids.
Submarines are also hybrid vehicles -- some are nuclear-electric and some are dieselelectric. Any vehicle that combines two or more sources of power that can directly or
indirectly provide propulsion power is a hybrid.

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.

I compiled this presentation recently to summarize key aspects around electric cars from a layman perspective. The study touches upon interplay between industry and state in key markets with some enhanced focus on Europe
Internal combustion engines produce appreciable emissions and are also less efficient at part loads. On other hand electric drives have zero emissions, but also very limited range. It is thus logical to combine the best aspects of both and the result is a hybrid vehicle. Optimum strategy would then be to use electric drive during slow moving city traffic, for acceleration and for hill climbing and IC engines at cruising speeds on highways. This would also results in reduced pollution in cities, along with improved mileage.
The engine on the conventional car is sized for the peak power requirement, which is seldom required in actual practice. The hybrid car uses a much smaller engine, whose size is kept closer to the average power requirement rather than the peak power. A smaller engine is always more efficient due to the reason that it would run at its optimum capacity most of the time as compared to a bigger engine running at part load most of the time.
Electric motor helps in several ways:
1. Provides extra power when the car is accelerating or climbing a hill.
2. Starts the engine, eliminating the need for a separate starter.
3. Provide regenerative braking to capture energy during braking

Fabrication of Hybrid Petroelectric VehicleIJERA Editor
In automobile sector, the need for alternative fuel as a replacement of conventional fossil fuel, due to its depletion and amount of emission has given way for new technologies like Fuel cells vehicles, Electric vehicles. Still a lot of advancement has to take place in these technologies for commercialization. The gap between the current fossil fuel technology and zero emission vehicles can be bridged by hybrid technology. Hybrid vehicles are those which can run on two or more powering sources/fuels. Feasibility of this technology is been proved in four wheelers and automobile giants like Toyota, Honda, and Hyundai have launched successful vehicles like Toyota prius, Honda insight etc. This technology maximizes the advantages of the two fuels and minimizes the disadvantages of the same. The best preferred hybrid pair is electric and fossil fuel. This increases the mileage of the vehicle twice the existing and also reduces the emission to half. At present, we like to explore the hybrid technology in the two wheeler sector and its feasibility on road. This paper deals with an attempt to make a hybrid with electric start and petrol run. Further a design of basic hybrid elements like motor, battery, and engine. As on today, hybrid products are one of the best solutions for all pollution hazards at a fairly nominal price. An investment within the means of a common man that guarantees a better environment to live in.
Electric Vehicles (EV) use a battery to store the electric energy that powers the motor. EV batteries are charged by plugging the vehicle into an electric power source. Hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs) and all-electric vehicles (EVs)—also called electric drive vehicles collectively—use electricity either as their primary fuel or to improve the efficiency of conventional vehicle designs.
Reduced fuel consumption and emissions, optimized fuel efficiency and performance, lower operational cost, rising conventional fuel costs are some factors that make use of EVs advantageous. However, tech and other challenges are in front of EVs to make them popular selling asset among masses. High EV price limit the current customer group to consist of primarily tech savvy and environmental ideologists, however, new research indicates that charging time and driving range are most influencing the purchase decision. Due to scale of production and technological development, it seems likely that there will be significant price erosion related to EV batteries over the next 10 years. This will most likely influence EV prices and increase sales.
Moreover, along with the gradual emergence of EVs- innovators and entrepreneurs are introducing new and visionary business models. Incidentally, EVs are sold on subscription- and rental companies are beginning to include EVs as part of their fleet of program. For example, as integrators or mobility service providers, the EV value chain creates opportunities for newcomers to participate and create value on mobility market. The integrators are the future industry actors, who will handle the integration between EV charging and intelligent home billing etc. Reportedly, ECOtality partnered Sprint Nextel and Cisco to deliver wireless connectivity for charging stations and home energy management solutions/controllers.
This report aims to highlight the drivers and inhibitors that influence the roll-out of electric cars in terms of adoption speed, cost and user acceptance. The report is largely based on the general market data, which has been analysed and correlated with the data from fleet test of electric vehicles which was conducted in and around the metropolitan area of Copenhagen (Denmark). The report also explores an analysis of comparative advantages of plug-in hybrid electric vehicles over EVs.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

because, under most ideal conditions,
efficiency of loop, battery to kinetic and kinetic
to battery charging is no greater than 50 %.
Also, it adds to cost, which may prohibit
customers for conversion.

20. Why change EV driving cycle
Prius changes to EV during congested traffic
conditions and runs on ICE on highways. OK for
urban driving cycles in Metro cities.
In other cities car users are driving in cities for
10 % distances and remaining on highways.
High speed running on highway obviously fuel
consumption is high.
With low powered, light weight PMBLDC hub
motors, it is proposed to run vehicle on ICE in
city traffic conditions and switching on to EV on
highway.

21. Results and Discussions
By using proposed lower power Hub Motors, up to
61 % saving is achievable on the existing cars.
Peak performance of the available drive line is
retained / assured.
Veh. existing electrical system is not disturbed.
Existing Hyd. Brakes with Disc brakes in rear.
No additional Instrumentation required.
Power Steering and A/c are driven by ICE, hence
ICE has to run on idling while running in EV mode.

22. Results and Discussions
…Cont.
Appropriate torque capacity of PM BLDC hub
motors can be selected for the particular
vehicle for conversion in to HEV, for deriving
optimum results.
Advantage of hub motors is that the output is
directly driving the wheels; hence the motors
efficiency is the only loss. Geared hub motors
add to varying torque reqyuirement.
Well to wheel energy efficiency for Prototype
HEV is measures at 0.87 km/MJ as against
0.64 for Insight and 0.56 for Prius models but
1.14 for Tesla (pure EV).

23. Conclusions
Proposed method is expected to reduce the fuel
consumption by 45 % to 61 % (with A/c & P/S).
Results can improve further, if the high Ah, light
weight batteries are utilized.
Possible to convert majority of the old cars with
front engine front wheel drive vehicles in to
Hybrid Electric car, without much of difficulty and
at reasonable cost.
Easy to implement in new veh. models –
Existing/introduced in future, by the vehicle
manufacturers.

…Contd.
Serviceability and life of components is
improved.
Increase Service life of ICE and driveline
components.
Reduced maintenance cost of ICE and driveline
assembly components.
ROI from 11 to 15 months @ 3000 km per
month.
