Recently, the Electronic Vehicle Symposium 27 was held in Barcelona. This conference presented a platform for exploring wireless technology, which has been a major subject in most headlines. Wireless charging is a topic that is still in need of more education and careful thought. Two major companies, Brusa, and Qualcomm displayed wireless solutions in the conference. Qualcomm is an American start-up while Brusa is a Swiss company that has many years of experience in engineering of electric vehicles. It is essential to get an overview and a basic understanding of wireless charging.
While everyone talks of wireless charging, that might actually not be the accurate term to use of the technology in question. This charging actually entails transmission of wireless power between a transmitting coil and a receiving coil through a magnetic field. The process of charging is unique, and starts when the car’s coil has changed the energy received in the form of electricity. It is essential for the parking pad to be somewhat large. A larger parking pad works better since the device should be quite tolerant to misalignment. The parking pad displayed by Brusa was thicker and larger compared to that of Qualcomm. The outlook of the Brusa unit was tough and industrial, while that of Qualcomm was more of home equipment. It was evident that the American corporation focused most energy and time towards design. A wide range of car receivers were also displayed by the American company.
With respect to safety, the representatives of both Brusa and Qualcomm said that their charging systems were safe. Both had a built-in obstacle-detecting device. If the device sees something interfering, the magnetic field is instantly switched off. Since both companies carried out several outdoor and indoor tests, safety ought not to be an issue in the future. Wireless Power Technology (WTP), commonly referred to as wireless charging is still a technology that is add-on. There is the tendency for all electric vehicles to have standard plugs. These plugs are somehow same as those applicable to computers. Nowadays, wireless Internet is available everywhere, but an Ethernet port is still present in most computers for emergency uses. It is evident that the cost of electric vehicles will rise because of wireless power transmission. Efficiency will also be an issue.
The fans of electric cars have proudly claimed that the efficiency of an electric motor is higher than that of a combustion engine. Generally, future electric-vehicle drivers may embrace wireless power transmission because of its convenience. However, cost and efficiency are major obstacles to its adoption.

Electric vehicle newbies may be surprised to find out that the vehicle’s electric charger is located on board. This equipment is deeply seated in the inner part of the car to convert an AC source to a DC. This makes it is possible to charge your vehicle’s battery pack. Nearly everybody knows that a charger is a wall-mounted box supplying 240 volts of electricity. Actually, a technical name for the box in question combined with a plug and code is EVSE or Electric Vehicle Service Equipment. An electric vehicle owner would need to install one of these at their home. We will shed light on purchasing an EVSE, which basically refers to an electrical device that allows drivers to connect their cars to an electricity source. There are a number of significant variations between different types of home chargers. Additionally, a few practices should be kept in mind.
It is advisable to purchase a charger to handle more than 30 amps. According to averages, a 30-amp service gives a driver the potential to get approximately an additional 30 miles range per hour. Similarly, 15 amps would give an additional 15 miles in charging hour. It is important to note that EVSE with 30 amps requires at least a 40 amps circuit breaker.
Most experienced electric vehicle drivers hold a general consensus that EVSE that is durable and with a high capacity costs approximately 1000 dollars. This cost could be quite less or double, excluding the installation costs. There are a number of features including connectivity and portability that could cause an increase in price. To reduce the cost, it is advisable to avoid such features. Most electric vehicle drivers could get free EVSE from the year 2010 through the year 2013.
If possible, it is advisable not to install an EVSE permanently. This implies that you need to have an electrician to install NEMA 14-50 outlet. A plug should then be put on a pigtail that is mounted to the EVSE. In case you decide to relocate at some point, you need to simply unplug the charger and then plug it to a different NEMA outlet. The approach mentioned is similar to a hard-wire installation in terms of costs.
With advanced technology, there are numerous smart grids and smart phones, which may compel electric vehicle owners to purchase EVSE that is Wi-Fi enabled. However, this move might not be a smart one. Connectivity would only add pointless complexity.

Last year, Volkswagen’s Chief of Electrification, Dr. Rudolph Krebs, claimed that Volkswagen had the aim of becoming the auto industry’s leader in electric vehicles. The commitment was reiterated in the Los Angeles Auto Show that was held last week. According to Dr. Krebs, the company will employ the most comprehensive e-market strategy. The company is spending money to create new powertrains. Dr. Krebs also mentioned the fact that Volkswagen had invested in the development of in-house electric vehicle competencies. These include employing more than 400 top specialists, manufacture and development of software, and offering training to approximately 70,000 employees so that they can cope with systems for electric traction. In the year 2014 there will be an all-electric Volkswagen E-Golf. This will be the first Volkswagen’s electric vehicle to enter the United States market. It is worth noting that the roadmap for Volkswagen electrification is associated with only two electric vehicles. These are E-Up for Europe, and the E-Golf. Meanwhile, in the next few years the company hopes to come up with more than nine plug-in hybrid cars.
A slide displayed by Dr. Krebs showed that from the year 2014, the bulk of those Volkswagen-produced plug-in hybrid cars will enter the market. Volkswagen’s officials specifically noted that Audi A3 e-tron PHEV would be available in the year 2015. This will be followed by an Audi Q7 plug-in car. There is a common script for all the mentioned models. This is in addition to an all-electric capability of 31 miles through a battery pack of 8.8 kilowatt per hour. The styling will be the same as that of conventional models. That is a good thing considering the design language of Audi cars. The total 203 horsepower originating from electricity and gas was more than sufficient for Los Angeles’ crowded streets.
With pure electric vehicle as the default, there are four different driver-selected modes. First and foremost, the vehicle is viewed as an electric vehicle. More blending of electric and electric is possible using an “auto” hybrid mode. Another mode is the “hold” mode”, whereby more gasoline is consumed in reserving electric power. “Charging” mode allows turning on of the gas engine to allow battery recharging. A driver rarely notices the transition to gas from the electric mode. The A3 e-tron can hold 5 passengers and a wagon format. This is combined with an all-electric range of 30 miles. This qualifies to be viewed as a convincing package. The corporate commitment of Volkswagen to battery-powered vehicles could be the winning touch.

There are a number of things to do before making the final decisions to purchase a plug-in car. Some of the factors or steps to take will be presented in this article.
It is fundamental to shop around prior to choosing or deciding to buy a plug-in vehicle. Despite the many differences between electric and gas vehicles, there is a key similarity. This similarity is the fact that a buyer has to go via a sales person. There are a number of sales people in different car dealerships. Dealerships often compete with one another for business. Therefore, once you have made a decision on a specific plug-in car type, it is recommended to visit or consult many dealerships in your area and choose one with a manageable deal. The small step of shopping around can often save several thousand dollars.
Considering the Incentives
Purchasing plug-in vehicles entails three key types of incentives. These incentives are rebates, perks, and tax credits. A tax credit of between 2,500 to 7,500 dollars is offered by Uncle Sam depending on the car type. It is important to note that the tax credits are applicable against tax liability in the future. Rebates are offered in the form of checks in malls. Other perk ranges include carpool lanes access for solo drivers and free parking.
Having Faith in the Car’s Battery
Among the greatest electric cars’ myths is that the owner will be slapped with a high bill to replace the car’s battery in a few years. This is however, unlikely to be the case. A key fact is that over many years there will be some range loss. The loss may perhaps be quite faster in regions that experience severely hot weather. Nevertheless, the battery warranties of plug-in vehicles are substantial, ranging from eight years and 100,000 miles. Some cars may have even longer warranties. The warranties cover all the problems or issues affecting the battery such as excessive range loss. There is no reason to fret because plug-in vehicle batteries can last as long as the vehicle’s lifetime.
Installing a Home Charger
Several studies have shown that the total cost of electric car ownership is lower compared to gas-powered cars. Installing a home electric-vehicle charger can be done for approximately 1,000 to 1,500 dollars.
Connecting with Other Electric Car Drivers
The final step is connecting with the vibrant community group of electric-vehicle drivers. With advanced Internet, it is now possible to connect to other electric-car shoppers and owners with just a click or two.

To increase electric vehicle chargers’ sales, should you use slower, speedier, simpler, smarter, or smaller equipment? These are among the major questions that companies manufacturing electric-vehicle supply equipment must address as they make the 2nd generation electric vehicle chargers. In the U.S., monthly sales of electric vehicles have been on the increase. For this reason, electric-vehicle supply equipment (EVSE) companies have attempted to find new techniques for sparking commercial and residential charging equipment demand, as well as differentiate the equipment they sell from those sold by their competitors. A recent research report published by Navigant Research stated that by the year 2015, there would be more than 400,000 electric-vehicle charging stations. The report also outlines two major areas or ways that variety can be embraced by manufacturers. These areas are built-in intelligence level and the speed of charging an electric vehicle.
The first generation of electric-vehicle chargers stressed the speed aspect. Hence, most companies manufactured 50-kilowatt electric vehicle chargers that could provide eighty percent of charge to an electric vehicle battery in fifteen minutes. It is however, essential to keep in mind that high-speed electric-vehicle charging can have a severe financial impact for owners of a building, especially if usage occurs during peak power demands. These demand charges can greatly cost a company. This is the main reason why majority of EVSE companies are providing chargers that are fast enough. Such chargers can supply up to twenty or twenty five kilowatts in terms of power. Additionally, the chargers are less costly to install and buy, which is likely to attract a larger audience. Most people can easily get back on the road in at most twenty minutes even at these slower rates. Many electric-vehicle drivers do not wait until their battery is empty before recharging.
There is an Electric Vehicle Symposium (EVS27) conference being held in Barcelona this week. In the conference, ABB will be one of the vendors and there will be a chance to see a 20-25 kilowatt DC electric-vehicle charger. A noteworthy fact about ABB is that they have a Terra 23 unit that has the ability to charge vehicles using either Society of Automotive Engineers (SAE) or CHAdeMO charging systems. Tesla Motors has a Supercharger network that is super-fast charging and provides 120-kilowat electric-vehicle charging. It is clearly evident that the options are getting smarter, simpler and cheaper for consumers looking to buy electric-vehicle chargers for their homes. A simple charger’s price has currently dropped to $500 from $1,000 dollars.

Plug-in hybrids are the same as traditional hybrid vehicles in that both have an electric motor and gasoline engine. However, plug-in hybrid vehicles have large rechargeable battery packs. Additionally, plug-in hybrid vehicles cover long distances without using gasoline. One can drive a plug-in hybrid car for up to 60 miles. Plug-in hybrid cars not only offer the advantages of owning an electric car, but also maintain a driving range that is the same as that of conventional cars. A plug-in hybrid driver may travel in a full electric mode and then a downsized gas engine when the electric charge is finished. In comparison to other conventional vehicles, plug-in hybrid vehicles have considerable benefits in terms of fuel efficiency. Depending on the model, a hybrid vehicle would achieve double of a conventional car’s fuel economy. Also, a plug-in vehicle would deliver two times a standard hybrid’s fuel economy.
Despite the mentioned benefits of plug-in hybrid cars, there are a number of criticisms that have been raised.
High Cost of Extra Batteries
Critics have asserted that owning a plug-in hybrid car is expensive because of the costs spent on the batteries. To counteract this claim, it has been noted that cheaper and more powerful batteries can be sold at prices that are a few thousand dollars less than those in today’s hybrids, once they are sold in high volumes by manufacturers. Recharging is mostly done at night.
Heavy Because Of Extra Batteries
Critics have also claimed that plug-in hybrid vehicles are heavy because of the additional batteries. In response to this criticism, supporters of plug-in hybrids have said that the cars have a low gas engine weight to offset the batteries’ extra weight. Fuel efficiency, especially at high speeds is mainly affected by aerodynamics.
Switching of Pollution to Power Plant
Critics have also noted that in plug-in hybrid vehicles’ power is produced from the electric grid. Consequently, pollution is simply switched from grids to power plants. Supporters of plug-in hybrid cars have responded to this criticism by stating that the emissions, particularly greenhouse gases are extremely lower compared to gasoline. This is the case even for an average car’s power grid. Vehicles that charge off-peak make use of power originating from the plants, and that do not go off at night. Most of the power used in most parts of the United States is obtained from cleaner sources including hydropower and natural gas. Capturing conventional emissions from power stations is much easier compared to doing so from millions of gas-powered cars.

Fujisawa Sustainable Smart Town (SST), which has several partners, but is led by Panasonic, is marketing its initial units. SST, located in Fujisawa Japan, has promised to deliver a green lifestyle including plug-in scooters, bicycles and electric cars. Fujisawa, a Tokyo suburb, is well known for its ambitious targets. This includes an overall seventy percent reduction in carbon dioxide from the levels of 1990. There are plans for approximately thirty percent of the total energy generated for the town to be renewable.
The new town, which is constructed on the site of the former Panasonic television industry, is taking shape. There are around fifty units that are in different completion states. The first new town owners will be witnesses in March 2014. By the time the town is fully built in the year 2018, it will have about three thousand residents. According to a Fujisawa Partner Accenture’s Senior Manager, Noboku Asakai, the novel town is a reflection of Japan’s future. The senior manager further added that there is an increasing energy demand. Although a third of the national energy was generated from nuclear, most of them shut down following the Fukushima disaster. One of the trending topics is carbon dioxide reduction. Japan has not been left behind and is striving towards the novel energy economy.
Fujisawa’s first houses are almost ready. It is essential to note that housing in Japan is costly. It costs around five hundred thousand dollars or more without considering any eco-features. The leader of SST project did not give the exact price of the units. It was however, acknowledged that the houses will be slightly expensive compared to conventional housing. The overall housing cost will be cheaper, owed to the low operating expenses. By American standards, the new town’s houses are small, and large by Japanese standards.
Although, there has been a declining rate of population growth in Japan, the country has been sluggish in adopting electric vehicles. This implies that the country is extremely far from achieving its goal of reducing emission as per the Kyoto agreement. Once the construction of the new town is completed, residents will be urged to drive or use electric cars. Charging will not only be ubiquitous, but electric car-based sharing and rental programs will be introduced. There are also plans to incorporate solar-powered stations to charge swappable bicycles and scooters. Asakai stated that Fujisawa residents who will not be driving will be more active, while the drivers will have to be more eco-friendly.

For its initial thirty five or so miles after fully charging, the Chevy Volt operates solely as an electric vehicle. During those miles, the car does not burn any gasoline. It draws energy from a lithium ion battery (400-pound) pack that contains 16KW energy hours. Only about fifty percent of that energy is consumed. This is a means of making sure that the batteries attain the warranted service of 100,000 miles. Since a range of thirty five miles is impractical, the Chevy Volt has an engine powered by one and a quarter liter of gas. However, the engine does not drive or operate the wheels. The power supplied is only used in operating the generator to sustain a battery charge adequate enough for the car to have another extra three hundred miles in range.
Unlike Nissan Leaf and the Toyota Prius, Chevy Volt does not have an iconic outward appearance. To enthusiasts, Chevy Volt is snazzy, while to other consumers, it is competent. There is no extraordinary feature about the car’s physical appearance. It has stylized side mirrors, black door panel insets, and a flat-top rear spoiler. Though a Chevy Volt has a pretty good look, people are less likely to turn their heads with disgust or delight when they spot it from a distance. Another difference is with respect to the drive’s athleticism. The car has an electric motor that is double the size of Prius’ electric motor. Hence, the power that Volt supplies to the wheels is instantaneous and stronger than that of its Prius counterpart.
The impressive acceleration or speed of Chevy Volt is another feature that distinguishes it from other hybrid cars. It is unfortunate that the engineers did not achieve huge success in providing a braking experience that is seamless. The initial action of the brake pedal that leads to regenerative breaking may feel loose for several drivers. A slightly uneasy hesitation may be felt when the brake is pushed further, depending on the surface of the road. After mastering how the Volt operates, the sensation is likely to disappear for many drivers.
A similar sophistication level that makes handling and accelerating a Volt so effective and fun is applicable to interior part. The seats are not only firm, but they are also comfortable. The materials have a high quality feel with few exceptions. The Chevy Volt continues to evolve, despite the fact that virtually all top engineers and executives from the car’s earliest days have shifted to other projects.

There are a number of factors to consider when calculating the total cost of owning an electric car. Here are some of the factors to take into consideration.
The Car’s Actual Price
Pinpointing a car’s MSRP is easy enough, but many calculations make use of the minimal base price instead of what is paid by most consumers prior to driving off the lot. Trim levels and options can add thousands of dollars. It is also essential to acknowledge the fact that there are deals and incentives, irrespective of the type or model of car. Such deals and incentives can lead to a several thousand dollars difference. For accuracy, it is advisable to use numbers that come from the dealers directly for the vehicle that your intend to purchase.
Electric cars have been in the market for a short time. Hence, it is quite difficult to know the appearance or even the value of a strong second-hand electric vehicle. Conventional hybrid cars have operated well in times of rising gasoline prices. The harsh reality is that the range of electric vehicles depreciates over time, particularly for cars powered by the battery and that do not have a thermal management system that is active.
It is commonly assumed that 0.12 dollars are needed for one kw-hour of electricity and approximately four dollars a kw-hour for a gas gallon. There is some doubt on whether the low costs of fuel would increase the competitive edge of electric cars over time. When the prices of gas spike, the edge may widen further. The actual kw-hour price differs widely across the United States, and is likely to swing further on the basis of season, utility rate plans, home solar and time-of-use programs. It is a tough challenge to forecast on actual electric vehicles.
On the basis of anecdotal data, it is clear that the miles clocked by electric vehicle owners annually are fewer compared to internal combustion vehicles. Therefore, it is problematic to use the countrywide mean of twelve thousand or so miles in a minimum cost per mile.
Costs of Maintenance
Electric vehicles are beneficial in that they do not require changes in oil and other exhaust systems’ maintenance costs. According to research studies, this is about a thirty-five percent cost decrease over time. Other calculations have found the equivalent of three or four percent maintenance costs per mile for electric vehicles. This is in comparison to combustion engine vehicles that have six percent maintenance cost per mile. Generally, all the factors mentioned above should be considered to find the total cost of owning an electric vehicle

Just like virtually anything in this life, electric cars are linked to a number of upsides and downsides. Here we will cover some of the cons and pros of vehicles that operate on electricity instead of petroleum.
Among the key pros of electric cars is that operating them is cheaper. Electricity is cheap and ubiquitous in most parts of the globe. Additionally, there is a big cost advantage that electricity has over gasoline. The cost per mile needed to fuel an electric car is a third to a quarter the gasoline cost, given the significant efficiency of electric vehicles in comparison to internal combustion models. Maintaining an electric car is also cheaper, since such cars do not have exhaust systems and therefore do not need oil changes.
Another pro of owning an electric vehicle is that it is not only quiet, but also quick. It will only take a single ride in a car powered by a battery to comprehend the improved quality of ride offered by an electric vehicle compared to a car with a combustion engine powered by petroleum. An electric vehicle is not only quiet, but is also smooth. Additionally, such vehicles offer a high torque or balance. Other additional pros include the fact that electric cars can be recharged at home and are not associated with tailpipe emissions.
Among the key cons of electric vehicles is their higher cost compared to gasoline-powered vehicles. The price range for most electric vehicles is 30,000 to 40,000 dollars. This is in comparison to midsized gasoline-powered cars such as Ford Focus and Honda Fit, which can be bought for at most 20,000 dollars. Another con of electric vehicles is lack of diversity. This means that there is a limited consumer choice. Most of the plug-in electric cars in the market are sub-compact or compact with a midsize range. The most popular electric vehicle has a polarizing style, which means that customers would either love or hate it.
The fact that it takes a long time to refuel electric vehicles is also a downside. An hour of charging an electric car from a 240-volt electricity source would add about 20 to 25 miles of range. This is why drivers planning to take several road trips are often advised to plug in before retiring to bed. Another con is the limited range of electric vehicles. The most affordable electric cars would have a range of 80 to 100 miles. Drivers are thus advised to properly plan unless they are driving electric cars with a back-up range-extending engine.
