ELECTRIC VEHICLES DEVELOPMENT


ELECTRIC VEHICLES DEVELOPMENT



Dynamic development of the electric vehicle market sets a number of challenges ahead for the EV market participants. Developing an effective EV charging infrastructure becomes a priority for the key market stakeholders. On average, current EV range is still limited to 60-80 miles on full charge (with normal charging time of 6-8 hours) which means that EV use range is expected to be limited to short and predictable routes in three main urban areas: work, home and commerce. Provision of charging infrastructure in the proximity to these areas is a first step toward expansion of EV. The next step is expansion of EV charging infrastructure at the key city points to match people’s flows. 

In many parts of the world, countries are taking advantage of the recent development in electrically powered vehicles to foster growth in their economy by encouraging engineering projects and green energy research and development. Poland for instance is making significant steps towards creating a plug-in vehicles charging infrastructure market recently. Regional Development Agency, responsible for local socio-economic development support and promotion, has initiated a project called “Creating Market for Electric Vehicles and Charging Infrastructure as a Foundation for Energy Independence”. According to the project, proper functioning EV charging infrastructure in Poland is perceived as an important part of the energy network transformation, which would consist of small and dispersed alternative sources of renewable energy (EV battery would function as loads while connected to the smart grid). Financed by the EU, this project provides €0,86 mln for delivery and installation of the EV charging station infrastructure. Five Polish cities are to be equipped with 120 EV charging points (330 vehicle couplers) by July 2010: 136 vehicle couplers in Warsaw (including 10 inductive charging stations), 54 in Gdansk, 54 in Katowice, 53 in Krakow and 33 in Mielec. “Such charging points would be located in public and easy-accessible locations and several additional solutions (ex. free parking at the point of charging) are being discussed at the moment”- says Jacek Janowski, Chairman of Green Stream Polska, main contractor of the project.

On the other hand, Japan makes an almost perfect test-bed for understanding how consumers relate to electric vehicles. The country is home to many hybrid-electric vehicles (HEV)and electric vehicle (EV) innovations, the government actively supports and incentivizes EV use, and consumers are environmentally aware and knowledgeable about alternative transportation options. It ranked first Mckinsey 7 company's EV Index (EVI) for January 2012, which measures readiness in terms of both EV supply and demand. Japans concentration population means travel distances are often short and charging infrastructure needs are not overwhelming. Same developmental gestures are also evidence In many countries and this not limited to any region.

Technology is what it takes and idea is the drive. With this, most organisations are looking towards the sun and other greener means that have proved effective and reliable. sooner or letter or world will be freed from the level of damaging pollutions it faces from carbon emission and other industrial waste pumped into the atmosphere on daily basis.

ELECTRIC CAR FRAME


THE FRAME OF FAME

The frame of the electric car is purposely designed to optimise speed and save power. Thus, they are built with altra-lightweight materials that are really tough. This frame provides the needed support and reduces drag, allowing the car to reach amazing speeds on its electrically powered motors. many designers has come up with various methods for design and has since flooded the market with different design concepts. We will focus on the frame, more specially, the suspension and floor of the electric car. The entire chassis is an amazing piece that translates into the results we have been seeing in recent times. It is truly unique. More so, the structural design of Automobiles determines the overall content and interior, based on space. With lesser weight and additional space, the electric car opens a new window of designs. Basically, it provides for less complexity in terms of organising.

Furthermore, while many decided to stay with more traditional concepts, known manufacturing and design technologies are often taken to its limits by combining the unibody structure with hydroforming and maximum use of structural adhesives, as well as laser welding, tailor-welded steel blanks, and roll forming. The process is computer interactive all along, optimizing sections, improving joints and using different steel qualities and material thicknesses at appropriate points in the design to create the optimum structure. A number of parts that would traditionally be created by sheet metal stampings can be replaced by one-piece hydro formed tubes. This required tight control during design of section perimeters and transitions and some unique joint designs.
stly, the key design material is aluminium. One may start wondering how an aluminium sheet that is so thin provides such tough support. This toughness is achieved through precision achieved by applying computing to construction. Machines are used for in cutting and forming while laser welding is mostly used to hold piece together. The main raw material for primary aluminium production is bauxite. Aluminium oxide is extracted from the bauxite, and is used in an electrolytic reduction process to produce primary aluminium. It takes roughly 4 – 7 tons of bauxite to produce 2 tons of alumina, which again yield 1 ton of aluminium. Primary aluminium is alloyed with other metals and is then fabricated into a range of products through casting, extrusion and rolling. In addition, it is far cheaper and lighter compared to some other metals.
In all, it all makes sense knowing how transformative this is and how it could help in reducing cost of production. Most students have used many alternatives, applying their techniques and concepts in the design and development of e-cars at their level.

ELECTRIC CAR BATTERY

THE BATTERIES BEHIND THE WELLS

Have you ever wondered what powers the electric car? Exactly. Knowing fully well that electric cars are powered by batteries, many thought comes to heart figuring out how much energy is required to power the amazing motors that spins the wheels of an electric car. So many questions relating to cost, durability, charge time, safety, supply, demand and more. Many are of the opinion that the electric car revolution which in fact promises a greener earth in the future can be too fast a conclusion judging by the pressure that may come on batteries manufactures. The key question remains "will battery manufactures be able to meet up with battery demands for these cars? To answer this, there is need to first understand the type of battery and their output as well.

Presently, there are great number of battery manufactures out there who produces millions of batteries every month, but in a situation where most electric cars are fitted with 8,000 batteries and above, it make a lot of sense to start questioning manufactures ability for meet up with growing demands which has recently been on the increase. We are going to take a quick look at these batteries and the advantages they off as well as the possibility we are not going to run out of batteries or materials for making them one day.

Technology and cost challenges  Current battery performance of lithium-ion batteries is not sufficient to be widely used for HEVs, PHEVs, and EVs.  In addition to necessary increases in energy and power density (performance), other improvements are needed in durability, safety, and cost.
Durability: Batteries in PHEVs and EVs are required to have reliable durability for deep cycles to keep longer life (The Institute of Applied Energy, 2008). Vehicle makers are aiming to develop lithium-ion batteries with a guaranteed five-year or 100,000 kilometer driving distance (Nishino, 2010). Deep cycles of lithium-ion battery decrease the battery capacity rapidly, but PHEVs and EVs will be charged after the battery-stored energy is almost depleted. In addition, the power of lithium-ion batteries decreases in cold weather. For use of electric vehicles in cold regions, further technology development will be necessary to overcome this problem. 

Safety:
 Lithium-ion batteries are vulnerable to short-circuiting and overcharging. Lead acid, NiCd and Ni-MH batteries perform safely even after short-circuiting and overcharging because they have low energy capacity and use inflammable electrolyte. However, when a lithium-ion battery short circuits, high electricity flows are created and the battery temperature increases to several hundred degrees within seconds, heating up neighboring cells and resulting in an entire battery combustion reaction (Jacoby, 2007). When lithium-ion batteries are unintentionally overcharged, the chemical structure of the anode and cathode are destroyed and some of the lithium ions form snowflake-shaped lithium metal deposits called “dendrites,” which can cause the battery to short circuit or, in a worse-case scenario, explode and catch fire. Impurities in the lithium metal can also contaminate the batteries and cause the formation of dendrites, potentially Lithium-ion Batteries for Hybrid and All-Electric Vehicles: the U.S. Value Chain  17 causing short circuits and explosions (Buchmann, 2007). To prevent overcharging, lithium-ion batteries must be sold as battery packs with very precise voltage control systems. In other words, cells cannot simply be installed into a given electronic application. Even though lithium batteries have a number of safety measures (see U.S. Value Chain section, page 31), further safety measures need to be developed for vehicle use.  Note, these standards varies from countries to countries, thus, there is need for the implementation to a universal standard.

COST
 The high cost of lithium-ion batteries for vehicle use is a critical concern. According to the most recent estimates available for batteries for vehicle use, the cost of lithium-ion is four to eight times that of lead acid and one to four times that of NiMH (Nishino, 2010). However, the cost of lithium batteries is expected to decrease significantly because the batteries will be increasingly used for many applications, such as uninterruptible power supply (UPS), forklifts, consumer electronics and backup power supplies. As the market grows and production scales up, manufacturers will be able to enjoy economies of scale. According to Deutsche Bank, the cost of lithium-ion batteries will decrease from $650/kWh in 2009 to $325/kWh by 2020 (Deutsche Bank, 2009).

The expectation that the owner of an electric car should be able to drive it both at blisteringly hot summer temperature and at subzero winter temperatures poses substantial engineering challenges. batteries can be optimized for both high and low temperature but it is difficult to engineer them to function over a wide range of temperature without incurring performance degradation. for instance, batteries optimized for performance and endurance in cold climates would rely use electrolytes and materials that allow high temperature storage. All these and many more are to be put into consideration during production of batteries and that means a lot. Hopefully, many studies are under way, studying different conditions and proffering various solutions for better result. Tesla Motors have been doing a good job in show casing these new capacities and capabilities and has proven how much punishment a battery can take and how far they can go, at that, they have continued to pull new amazing records.

THE ELECTRIC CAR

THE MOTOR THAT WORKS IT ALL
Every thing about the electric car is fascinating and proves we can (only if we want to) improve our condition of living and as a result reduce the risk of diseases caused by emission from combustion engines.  Electric cars have a motor just like conventional, internal combustion engine cars. The difference is that the power supply is derived from battery-stored electricity rather than the mechanical power derived from burning gasoline. The batteries used in electric cars vary in design, and include the lead-acid type familiar to all conventional car owners, lithium ion, similar to those used in laptops and mobile phones, but once again much larger, molten salt, zinc-air, and various nickel-based designs.


An electric motor (DC)
In an electric vehicle the traditional gasoline or diesel engine and fuel tank is replaced with an electric motor, a battery pack and controllers. The vehicle also has a controller that powers the electric motor that uses rechargeable batteries as its energy source. The motor itself can be either AC or DC. The main advantage to electric vehicles is that the motor and battery configuration allows the vehicle to run more fuel-efficiently. DC motor installations tend to be easier and less expensive to build. DC motors also have an overdrive feature which means that for a short period of time the motor will accept more energy and deliver more horsepower as a result. This feature is useful in a vehicle because it can help during acceleration. The motor, however, cannot be run in overdrive too often because the motor will overheat and could malfunction.

AC motor installations are more expensive than DC installations. They usually use a three phase AC motor that allows regenerative braking. This means that during braking the motor acts in reverse as a generator and delivers power back to the batteries. 15% of the energy used for acceleration can be recovered using regenerative braking. This amount is not enough to fully recharge the battery pack, but it will extend the range of the vehicle.


In a DC electric car, the controller delivers the power from the batteries to the engine in a controlled way. The controller pulses the power to the engine usually at a frequency of 15,000 times per second. The frequency is outside of normal human hearing which is why the controller and motor is silent. In an AC electric car, the controller needs to create three Electric vehicles T-611-NYTI-21652 New Technology Page 8 pseudo-sine waves. The controller takes the DC voltage from the batteries and pulses it to the motor. In addition, the controller via transistors reverses the polarity of the voltage. (McClellan, 2010) The biggest technology challenge for electric vehicle engineers comes with the batteries. Lead acid batteries are not ideal for the job because they are heavy and bulky, have a limited capacity, take a long time to charge, have a short life, and are expensive. Therefore, either lithium-ion or nickel metal-hydride (NiMH) batteries are used instead. NiMH batteries double the range of the car and have a long useful life. However, the cost of the batteries is at least ten times higher than lead-acid batteries, and like lead-acid batteries, they are not good for the life of the vehicle.

An electric vehicle also has a normal 12-volt lead-acid battery. This is the same type of battery that
every vehicle has and is used to power all of the vehicle accessories such as the radio, lights, power windows, etc. An electric car needs a DC to DC convertor to convert the voltage from the main battery back to 12 volts and to keep this battery charged. Finally, an electric vehicle needs a charging system to recharge the batteries. The two main functions of the charging system are to charge the batteries as quickly as possible and to avoid damaging the battery pack during the charging process.

The technology and components used in an electric vehicle is constantly evolving, and engineers are finding new solutions every day to the technological issues. It looks like electric vehicles are here to stay, and the battery and other electric vehicle technology will only continue to improve.

Now lets take a look at the balancing and battery placement on this impressive machine and maybe you will start to understand better the level of space that has been created as well as the impressive finishing that's was put into this great design. Most designers prefer to pack the batteries just beneath. At that, it fits in most and considering the type of battery being used and how compact it can be, the shape and design just varies. Surprisingly, this batteries are highly efficient and reaches a long range (distance) and brings it head-on with regular combustion engines. For the advantages if gives and its eco-friendly nature, it has also proven to be cost effective and with time, we hope this revolution spans across the globe.

THE ELECTRIC CAR REVOLUTION

THE ELECTRIC CAR REVOLUTION

Now while surfing through the net for more exciting innovations on the new electric zooming
zoomer, I came across a whole lot of interesting stuffs and I tell u its a lot of fun. I found this one on this blog, it caught my attention because it holds a lot of details. I figure it might interest you too, take a look, its titled "
The Electric Car Revolution"

Here’s how electric cars have grown in the marketplace over the past four years.
Globally, at the end of 2010, there were 25,000 electric cars on the road. At the end of 2011, there were more than three times that amount: 80,000. At the end of 2012, there were 200,000, two-and-a-half times more. And at the end of 2013, there were 405,000.



Translation? The number of electric cars on the roads has been doubling or tripling every year for the past several years. Although electric cars represent just approximately one percent of the automobile market, the growth trend is similar to what we’ve seen for every other disruptive technology: washing machines, dishwashers, computers, laptops, cell phones, smartphones, cassette tapes, CDs, MP3 players, and digital cameras, to name a few. From a certain point of view, we could say that electric cars are about halfway to market domination.2
Not every technology that starts out strong ends up taking over. These first several years of electric car growth follow the disruptive technology pattern, but they don’t guarantee an “electric vehicle revolution,” as many in the industry refer to it. For a technology to replace another so completely, it needs to be: 1) much better, 2) cheaper, or 3) both. You aren’t going to buy an electric car simply because other people are beginning to do so. You’re going to buy an electric car because it makes much more sense for you. I’m convinced that for the average person, this time will come – this year, next year, or sometime in the coming decade.

Convenience

Whether we like it or not, we are a convenience-based society. So many of our products and services are based around convenience, and that’s true for electric cars as well. How much time do you spend each year going to the gas station, filling up, paying, and getting back on the highway? With an electric car, all you do is plug in when you get home and unplug when you are ready to leave.
Unfortunately, there’s so much hype about the shorter range of electric cars on a full charge compared to gasoline-powered cars on a full tank that an outsider might have the impression that electric cars are less convenient. But very few people drive 80 miles in one day on a regular basis. In the few instances when you do drive that distance, renting or swapping a car is an option.
In discussions about limited range, affordable electric cars such as the Nissan LEAF are often cited as an example. The situation improves if you can afford a Tesla Model S, widely considered the best mass-manufactured car on the market, gas or electric. For those of us not in the luxury car category, the technology is quickly improving. In a handful of years there will be many electric cars available that will have a range of up to 200 miles.
Convenience goes beyond charging. Electric cars have very few moving parts and their motors are much simpler than gasoline engines. Forget oil changes (not needed), busted tubes and valves (not used), muffler problems (nonexistent), smog checks (zero-emission vehicles are exempt), brake problems (regenerative braking helps your brakes to last much longer), and transmission problems (no transmission, no problems).

Pleasure

The other big seller is pleasure. To my mind, there’s no doubt: electric cars are much more pleasurable to drive. They are extremely smooth and quiet, and electric motors are about three to four times more efficient than gasoline engines.
But the best part about the performance of electric cars is what’s called instant torque. Even if an electric car and a gasoline car have the same 0-60mph rating (for example, seven seconds), the electric car feels much quicker because of that initial burst. It’s termed the "EV smile."
The smooth ride makes driving fun, but also easier and less stressful. The most nerve-wracking aspects of driving are when you have to accelerate onto a highway with fast-moving vehicles, turn across a few lanes, or accelerate into a roundabout. The instant torque that electric cars offer lets you do all of this much more quickly and easily. This, along with the convenience factor, is what will sell electric cars to the average person, once they do a test drive and realize what these modern vehicles offer.

Money

Time is money, so the massive time savings you get from not having to go to the gas station, in for an oil change, and to the mechanic will amount to a great deal. However, electric cars actually save you literal money. They are approximately three to four times more efficient than gasoline-powered cars. The most efficient hybrid on the U.S. market, the Toyota Prius, gets 50 mpg. The most efficient electric car on the U.S. market, the BMW i3, gets 124 mpg equivalency (mpge). The average new car in the U.S. gets about 25 mpg. The most popular electric car, which costs a little bit less than the average new car before any financial incentives, gets 114 mpge, making it four times more efficient than the average new car. (The average new car costs a little over $30,000, while the Nissan LEAF costs $28,800 before any financial incentives, $21,300 after the federal EV tax credit).

Annual Cost of Ownership

Annual Fuel Use: the amount of fuel excluding electricity (gasoline, E85, diesel, etc.) used by this vehicle in a year. CNG use is in gasoline equivalents (GGE). One GGE of CNG is an amount of CNG that has the same energy content as one gallon of gasoline.
Annual Electricity Use: the amount of grid electricity used by this vehicle in a year. This value will be zero for hybrids or other vehicles that do not plug in.
Annual Fuel/Electric Cost: the cost of all fuel used by this vehicle in a year (including gasoline, electricity, or other fuels).
Annual Operating Cost: the first year operating costs (including fuel, tires, maintenance, registration, license, and insurance).
Cost Per Mile: first year operating costs (including fuel, tires, maintenance, registration, license, and insurance) per mile traveled.
Annual Emissions (lbs CO2): Amount of greenhouse gases emitted by this vehicle in a year.
There are many factors to take into account when looking at cost of ownership: upfront expenses, fuel, maintenance, financing, and longevity. After considering these factors, I’ve found that in many cases a person ends up saving thousands, if not tens of thousands, with an electric rather than a gas car. The payback time can be as short as two to three years, and it’s almost always within five years.

Cumulative Cost of Ownership by Year Assumptions

The featured graph shows the cumulative cost of ownership by year for each vehicle, including fuel, tires, maintenance, registration, license, insurance, and loan payment. The tool used to generate the graph assumes a five-year loan with a 10 percent down payment. Year one on the graph represents the 10% down payment plus the first year’s total operating costs. For more information about the information used, visit the Alternative Fuels Data Center website
However, that’s not the end of the money story. Think about it: the cell phone you bought 10 years ago was much different than the one you have today. In a few years, gasoline will be more expensive and electric car technology will be much cheaper. Electric cars will be much better and more cost-competitive in five years than they are today.

Global Benefits

Let’s not forget that electric cars have broader advantages than those that benefit just the individual owner. They cut our dependence on oil, and thus reduce our need to defend oil supplies in foreign nations. They don’t create any direct pollution or global warming emissions compared to conventional vehicles. In addition, there are solar panels available which allow you to drive on sunshine. Reducing oil dependence, air pollution, water pollution, global warming, and their myriad associated problems is something many people genuinely care about. This makes the switch to electric cars that much easier and more logical.

Supply & Demand

It’s worth noting that the technology behind electric cars is fairly new. Costs are coming down rapidly. As more people buy them, manufacturing processes will improve and there will be economies of scale that drive down costs. It’s a virtuous circle. In the case of gasoline-powered cars, the price of oil and gasoline, which are limited resources, will continue to increase.
Back when gasoline cars started to take over the market from electric cars, people like Henry Ford’s wife stuck with their electric cars because of how easy, convenient, and pleasant they were to drive. Thanks to wonderful advances in batteries, as well as improvements in automotive technology, we’re again entering a period where people will choose electric over gas. Eventually, the tables will turn again and gasoline cars will be the historic oldies that few people have ever driven.
*I’m using "electric cars" inclusively in this article in order to include plug-in hybrid electric cars and extended-range electric cars as well as 100% electric cars.

THE FORMULA e

TECH THE FORMULA-e
Formula E is a ground-breaking FIA single-seater championship and the world's first fully-electric racing series. 
The inaugural season began in Beijing in September 2014, ending in London in June 2015, with the series competing in 10 of the world's leading cities. The championship sees nine teams, each with two drivers, racing on temporary city-centre circuits to create a unique and exciting race series designed to appeal to a new generation of motorsport fans.
Formula E aims to represent a vision for the future of the motor industry, serving as a framework for R&D around the electric vehicle, accelerating general interest in these cars and promoting clean energy and sustainability.
Formula E also operates as an 'open championship', allowing teams and manufacturers the opportunity to showcase their own electrical energy innovations. Working to the technical specifications set out by the FIA, teams will focus their efforts on improving and developing powertrains and battery technology, with the aim of this filtering into the everyday electric vehicle market.
The championship centres around three core values of Energy, Environment and Entertainment and is a fusion of engineering, technology, sport, science, design, music and entertainment - all combining to drive the change towards an electric future.

Once all said and done, finally the formula e takes the centre stage, proving to the world the ability of the electric revolution which is fast proving its capabilities and efficiency in terms of eco-preservation. The earth is filled with energies that are renewable and friendly yet, the world governments have suppressed every idea, innovation and inventions the sort to introduce this idea and make it a reality. Not only are they renewable and friendly, they are cheaper (if not free) and to an extent can be generated in smaller scale but no! The world government will not bend to that and will stop at nothing until it sacrifices humanity for the benefit of the very few, the one percent because its all about the business.

THE RYTHM OF TECH

Tech brings the rythm of life and make the world a song full of life.
