Electric vehicles were pursued early in the 20th century but gas-powered cars became dominant due to easier mass production. Interest revived in the 1960s due to environmental concerns, but high battery costs remained a challenge. Modern electric cars are purpose-built from the ground up with lightweight materials and aerodynamic designs to maximize energy efficiency and range. Batteries, electric motors, and regenerative braking systems are optimized while passenger comforts are retained.

An electric vehicle (EV) is one that operates on an electric motor, instead of an internal-combustion engine that generates power by burning a mix of fuel and gases. Therefore, such as vehicle is seen as a possible replacement for current-generation automobile, in order to address the issue of rising pollution, global warming, depleting natural resources, etc. Though the concept of electric vehicles has been around for a long time, it has drawn a considerable amount of interest in the past decade amid a rising carbon footprint and other environmental impacts of fuel-based vehicles.

Combined Transmission System for hybrid vehicle is the concept of meshing the dual power source - Electrical and Fuel Engine Power. This system based on the chain drives, simple mechanism makes the good operation and it has less maintenance. Normally hybrid vehicle have dual power but alignment of the sources are one in the front another one in the rear respectively. This system fully differ from that, here dual power will act the same side drive.

An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft. For road vehicles, together with other emerging automotive technologies such as autonomous driving, connected vehicles and shared mobility, EVs form a future mobility vision called Connected, Autonomous, Shared and Electric (CASE) Mobility.
Does ELECTRIC VEHICLES STOP CLIMATIC CHANGE.pptx19214Shashank
This ppt gives information that does electric vehicles stop climate change or not
The extraction process of lithium is very resource demanding and specifically uses a lot of water in the extraction process. It is estimated that 500,000 gallons of water is used to mine one metric ton of lithium.[5] With the world's leading country in production of lithium being Chile,[6] the lithium mines are in rural areas with an extremely diverse ecosystem.[7] In Chile’s Salar de Atacama, one of the driest places on earth, about 65% of the water is used to mine lithium; leaving many of the local farmers and members of the community to find water elsewhere.[8][9] Along with physical implications on the environment, working conditions can violate the standards of sustainable development goals. Additionally, it is common for locals to be in conflict with the surrounding lithium mines. There have been many accounts of dead animals and ruined farms in the surrounding areas of many of these mines. In Tagong, a small town in Garzê Tibetan Autonomous Prefecture China, there are records of dead fish and large animals floating down some of the rivers near the Tibetan mines. After further investigation, researchers found that this may have been caused by leakage of evaporation pools that sit for months and sometimes even yearsLithium-ion batteries contain metals such as cobalt, nickel, and manganese, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills.[11] Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries.
The primary industry and source of the lithium-ion battery is electric vehicles (EV). Electric vehicles have seen a massive increase in sales in recent years with over 90% of all global car markets having EV incentives in place as of 2019.[23] With this increase in sales of EVs and the continued sales of them we can see a significant improvement to environmental impacts from the reduction of fossil fuel dependencies.[24] There has been recent studies that explore different uses for recycled lithium ion batteries specifically from electric vehicles. Specifically the secondary use of lithium ion batteries recycled from electric vehicles for secondary use in power load peak shaving in China has been proven to be effective for grid companies.[25] With the environmental threats that are posed by spent lithium-ion batteries paired with the future supply risks of battery components for electric vehicles, remanufacturing of lithium batteries must be considered. Based on the EverBatt model, a test was conducted in China which concluded that remanufacturing of lithium-ion batteries will only be cost effective when the purchase price of spent batteries remains low. Recycling will also have significant benefits to environmental impacts. In terms of greenhouse gas reduction we see a 6.62% reduction in total GHG emissions with the use of remanufacturing

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.

1. Electric Automobile
Unlike the gas-powered automobile, the electric automobile did not easily develop
into a viable means of transportation. In the early twentieth century, the electric car
was vigorously pursued by researchers; however the easily mass-produced
gasoline-powered automobile squelched interest in the project. Research waned
from 1920-1960 until environmental issues of pollution and diminishing natural
resources reawakened the need of a more environmentally friendly means of
transportation. Technologies that support a reliable battery and the weight of the
needed number of batteries elevated the price of making an electric vehicle. On the
plus side, automotive electronics have become so sophisticated and small that
they are ideal for electric vehicle applications.
Raw Materials
The electric car's skeleton is called a space frame and is made of aluminum to be
both strong and lightweight. The wheels are also made of aluminum instead of
steel, again as a weight-saving method. The aluminum parts are poured at a
foundry using specially designed molds unique to the manufacturer. Seat frames
and the heart of the steering wheel are made of magnesium, a lightweight metal.
The body is made of an impact-resistant composite plastic that is recyclable.
Electric car batteries consist of plastic housings that contains metal anodes and
cathodes and fluid called electrolyte. Currently, lead-acid batteries are still used
most commonly, although other combinations of fluid and metals are available with
nickel metal hydride (NiMH) batteries the next most likely power source on the
electric car horizon. Electric car batteries hold their fluid in absorbent pads that
won't leak if ruptured or punctured during an accident. The batteries are made by
specialty suppliers. An electric car like the General Motors EV1 contains 26
batteries in a T-shaped unit.
The motor or traction system has metal and plastic parts that do not need
lubricants. It also includes sophisticated electronics that regulate energy flow from
the batteries and control its conversion to driving power. Electronics are also key
components for the control panel housed in the console; the on-board computer
system operates doors, windows, a tire-pressure monitoring system, air
conditioning, starting the car, the CD player, and other facilities common to all cars.
Plastics, foam padding, vinyl, and fabrics form the dashboard cover, door liners,
and seats. The tires are rubber, but, unlike standard tires, these are designed to
inflate to higher pressures so the car rolls with less resistance to conserve energy.
The electric car tires also contain sealant to seal any leaks automatically, also for
2. electrical energy conservation. Self-sealing tires also eliminate the need for a spare
tire, another weight- and material-saving feature.
The windshield is solar glass that keeps the interior from overheating in the sun
and frost from forming in winter. Materials that provide thermal conservation reduce
the energy drain that heating and air conditioning impose on the batteries.
Design
Today's electric cars are described as "modern era production electric vehicles" to
distinguish them from the series of false starts in trying to design an electric car
based on existing production models of gasoline-powered cars and from "kit" cars
or privately engineered electric cars that may be fun and functional but not
production-worthy. From the 1960s-1980s, interest in the electric car was profound,
but development was slow. The design roadblock of the high-energy demand from
batteries could not be resolved by adapting designs. Finally, in the late 1980s,
automotive engineers rethought the problem from the beginning and began
designing an electric car from the ground up with heavy consideration to
aerodynamics, weight, and other energy efficiencies.
The space frame, seat frames, wheels, and body were designed for high strength
for safety and the lightest possible weight. This meant new configurations that
provide support for the components and occupants with minimal mass and use of
high-tech materials including aluminum, magnesium, and advanced composite
plastics. Because there is no exhaust system, the underside is made aerodynamic
with a full belly pan. All extra details had to be eliminated while leaving the
comforts drivers find desirable and adding new considerations unique to electric
automobiles. One eliminated detail was the spare tire. The detail of the rod-like
radio antennae was removed; it causes wind resistance that robs energy and uses
energy to power it up and down. An added consideration was the pedestrian
warning system; tests of prototypes showed that electric cars run so quietly that
pedestrians don't hear them approach. Driver-activated flashing lights and beeps
warn pedestrians that the car is approaching and work automatically when the car
is in reverse. Windshields of solar glass were also an important addition to regulate
the interior temperature and minimize the need for air conditioning and heating.
Among the many other design and engineering features that must be considered in
producing electric cars are the following:
Batteries that store energy and power the electric motor are a science of
their own in electric car design, and many options are being studied to find
the most efficient batteries that are also safe and cost effective. An electric
motor that converts electrical energy from the battery and transmits it to the
drive train. Both direct-current (DC) and alternating current (AC) motors are
used in these traction or propulsion systems for electric cars, but AC motors
do not use brushes and require less maintenance.
A controller that regulates energy flow from the battery to the motor allows
for adjustable speed. Resistors that are used for this purpose in other
3. electric devices are not practical for cars because they absorb too much of
the energy themselves. Instead, silicon-controlled rectifiers (SCRs) are
used. They allow full power to go from the battery to the motor but in pulses
so the battery is not overworked and the motor is not underpowered.
Any kind of brakes can be used on electric automobiles, but regenerative
braking systems are also preferred in electric cars because they recapture
some of the energy lost during braking and channel it back to the battery
system.
Two varieties of chargers are needed. A full-size charger for installation in a
garage is needed to recharge the electric car overnight, but a portable
recharger (called a convenience recharger) is standard equipment for the
trunk so the batteries can be recharged in an emergency or away from
home or a charging station. For safety, an inductive charger was created for
electric cars with a paddle that is inserted in the front end of the car. It uses
magnetic energy to recharge the batteries and limit the potential for
electrocution.
