Phev report
Hybrid vehicles combine two power sources, such as an internal combustion engine and electric motor, to improve fuel efficiency. They produce less emissions than conventional vehicles and can be charged using renewable energy. Plug-in hybrid electric vehicles (PHEVs) have both electric-only range and gas engine range, allowing them to overcome limitations of battery-only electric vehicles. PHEVs are well-suited to typical daily driving patterns of under 50 miles per day. Regenerative braking captures kinetic energy and stores it in the battery. While hybrids offer improvements now, fully electric vehicles face challenges of high costs, limited range, and long charging times, making hybrids a practical interim solution.

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.

Fuel Cell Powered Car.pptx
Fuel Cell Technologies
The document summarizes information about fuel cell technologies. It discusses how hydrogen is the most abundant element in the universe and can be used as an energy carrier. It then provides details on how fuel cells work, including that they emit only clean water. The document compares fuel cells to batteries and provides specifications for fuel cells in cars. It notes that fuel cell cars refuel in 3-7 minutes, have emissions of only clean water, and are quiet and efficient like conventional cars. The document also discusses the development of fuel cell technologies over the last 20 years and increasing adoption of hydrogen-powered fuel cell electric vehicles and buses.
Fuel car cell fuel car
This document summarizes a study comparing the fuel efficiency and greenhouse gas emissions of future fuel cell vehicles (FCVs) and internal combustion engine vehicles (ICEVs). The study models mid-size family sedans powered by advanced fuel cell and internal combustion systems that could be commercialized by 2020. It makes optimistic assumptions about future fuel cell performance to determine how competitive FCVs could be compared to ICEVs. The results show that even under optimistic fuel cell assumptions, there is no clear advantage of one technology over the other when considering total life cycle energy use and greenhouse gas emissions. Both FCVs and ICEVs could achieve significant reductions compared to current vehicles through advances in powertrains and reductions in vehicle weight and aerod
Supercapactors
This document summarizes a project that focuses on evaluating supercapacitors for use as energy storage in electric and hybrid vehicles. It finds that supercapacitors can provide high fuel economy improvements for a Prius-sized vehicle if they can store 125 Wh of usable energy at 90-95% efficiency. Vehicle tests also showed that supercapacitors performed as expected and achieved higher fuel economy than batteries due to their higher round-trip efficiency. The document concludes that combinations of supercapacitors and advanced batteries may prove most advantageous for energy storage in future plug-in hybrids.
Effects of Degree of Hybridization and Vehicle Driving Cycle on the Performan...
This document discusses a study that uses simulation software to analyze the performance of a fuel cell-battery hybrid electric vehicle under different configurations. The study varies the degree of hybridization (the ratio of battery power to total vehicle power) for a 2021 Toyota Mirai fuel cell vehicle model. It finds that increasing the degree of hybridization to 68.7% improves fuel economy by 16.3% compared to the original vehicle specifications. The best-performing configuration is then tested under different driving cycles to evaluate performance under various driving conditions.
hybrid electric truck document
The document discusses hybrid electric trucks (HETs). It provides details on the key components of HETs including lithium-ion batteries, electric motors, generators, and power converters. It describes the two main types of powertrain systems for HETs - series and parallel. The series system has no direct mechanical connection between the engine and transmission, allowing the engine to run at peak efficiency. The parallel system allows both the electric motor and engine to power the vehicle directly or together. Charging can occur through standard outlets, charging stations, regenerative braking, and with a range extender during low battery voltage. Driving an HET differs in not requiring a clutch compared to mechanical vehicles.
Adding Solar Power To Hybrid Cars
The document proposes adding solar panels to hybrid cars to make them more efficient and environmentally friendly. It notes that while electric and solar cars have limitations, hybrids using both gasoline and electric motors are currently practical. It suggests installing solar panels on rooftops to charge batteries powering electronic components and air conditioning when the car is stopped or moving, reducing fuel consumption. This "three-way hybrid" approach was successfully tested on solar-powered truck air conditioning. The document concludes that supplementing hybrid cars' electrical systems with solar energy takes advantage of available sunlight and saves energy without compromising features.

Fuel Cell
Fuel cells generate electricity through an electrochemical reaction between hydrogen and oxygen without combustion or pollution, producing only water and heat. They have the potential to power vehicles cleanly and efficiently. Key challenges include reducing the size, weight, and cost of fuel cell systems while improving durability, reliability, and the ability to process hydrocarbon fuels into hydrogen. Researchers are working to address these issues and apply fuel cell technology to transportation.
Hybrid car Advanced vehicle technology
The document discusses different types of hybrid vehicles. It describes the key components of a gasoline-electric hybrid car, including a gasoline engine, fuel tank, electric motor, generator, batteries, and transmission. Hybrid vehicles are classified into three main types: micro hybrids, which have a motor to assist with starting and accessories; mild hybrids, which have a more powerful motor to support starting and provide supplementary torque; and full hybrids, where the electric motor can power the vehicle on its own as well as charge via regenerative braking.

Fabrication of Hybrid Petroelectric Vehicle
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.
