Wireless Electric Car Charging Takes Off in London

In 2012, the matter of wireless charging of electric cars became a major talking point as technology companies took major steps to make it popular

Qualcomm and Charge master

Qualcomm, a mobile technology market leader has united with the London Mayor and UK government. They plan to release a set of wireless electric charging stations for trails in London. There will be 50 different variants of electric cars being used including some Addison Lee taxis. Qualcomm's wireless electric vehicle charging technology is also known as Inductive Power Transfer (IPT). Electric charging kits will be provided by Chargemaster, which will be installed around London.

A major benefit of wireless charging stations is the convenience factor. No longer will electric car drivers have to step out and connect wires to their cars. The technology clearly indicates a step forward within the electric car industry. Such innovation is sure to be heavily relied upon in the future, as electric cars become cheaper and cheaper as they more are purchased. In essence wireless charging stations will add more flexibility to owners. It may also lower car insurance premiums too, adding more security to the way electric vehicles are actually charged.

They are expected to into force in the near future according to both Chargemaster and Qualcomm. First the trails must prove to be successful. One potential hindrance of the technology is the length of time in which a battery needs to fully charge. Some sources believe that the charging points could take up to four hours to give enough power for a whole battery. Will people have enough time to wait around for four hours?

The trails will be costly and will involve the analysis of many factors in order to determine whether it is a success or not. Trails are not expected to be a direct hit or miss in many respects. Depending on how the technology is used, developers could redesign certain aspects or create new elements that add to the technology. Chargemaster have confirmed already that the important aspects of the technology are already in place.

If the trails were indeed a success, this would mean that many public charging points around the UK would have to be rebuilt in order to adapt. Current electric cars will also not be able to simply roll on and utilise the technology instantly but none of them possess the technology to adapt to the system yet. This is where car manufacturers themselves would need to invest and ensure that their vehicles are able to adapt to the charging stations. Their vehicles would somehow need to have the ability to be charged wirelessly.

It is unclear as to when the trails will begin and end as of yet. When they do commence there will be plenty of interest from the public. It may even entice motorists to purchase an electric car.

How it all works

Qualcomm's IPT system works in a complex way. A transmitter pad connects to the vehicle's electric battery via the receiver pad. The receiver and transmission pad must be 400mm apart. The transmitter is conveniently installed within the ground with the receiver pad installed into the base of the car, ensuring a connection can easily be established. This allows the driver to simply drive over the transmission pad in order for the electric battery charging to safely commence.

The system sounds complicated but is in actual fact very easy to use. Even the most non-technical users will have no trouble charging their car using this method.

AC Motors for Electric Cars

ByGil Norman

Electric cars have been around for a very long time now but the idea of driving one has never really caught on with the public until recently. The difference between an electric car motor and a hybrid is that electric cars are powered exclusively by electricity. Unlike a hybrid that uses a battery and motor to improve efficiency of its gasoline-fueled motor.

Batteries have improved over the years. The storage and cost of production of the batteries needed to power electric cars have always greatly changed. They are now more efficient, less expensive, and perform much longer than the outdated batteries of yesterday.

As you may be well aware, the motor is the heart of any vehicle. It is often the motor that is defining and sometimes limiting its performance. Electric cars can use either an AC or DC motor. Majority of the DC motors used in electric cars come from the electric forklift industry and may run from 96 to 192 volts.

If the electric vehicle is powered by an AC motor then the probability of it running 3 phase AC motor at 240 volts is high. It might also have its own 300 volt battery pack. DC motors are no doubt simpler and less expensive compared to its AC electric car motor counterpart. A typical DC motor will be around in the 20,000 watt - 30,000 watt range while a typical controller will be in the 40,000-watt to 60,000-watt range (for example, a 96-volt controller will deliver a maximum of 400 or 600 amps). The nice thing about DC motors is that you can overdrive them.

Now let us compare that to the AC electric car motor. An AC motor selection or AC controllers may require a matching motor and most of the AC motors that are being marketed for electronic vehicles may come with a controller. The controllers that come with it may often include a built-in charger and DC-DC converter.

The power AC inverter is the main part of the electrical system of the AC EV motor car, and its role is simple. It should effortlessly convert the battery energy to the form that is deemed usable for the AC motor, and to deliver the right amount of this energy per driver's demand.

AC installations allow you to use almost any kind of industrial three-phase AC motor. This is an advantage for you because that can mean that finding a motor with a specific size, power rating, and shape is so much easier to do. Another advantage of AC motors in electric cars is that most of them have a regen feature built into them. What that means is that when you hit the breaks or during breaking the AC EV motor in your vehicle turns into a generator and delivers power back into your batteries.

Other advantages when using or choosing the AC electric car motor are; electronic reverse, ability to adapt exact characteristics of the motor which also includes the throttle and brake potentiometers parameters, battery, and other hardware parameters via software, integrated components (main contactors and DC-DC converter), lack of brushes, high top RPM limit (about 10,000 for this motor), water cooling and high reliability.

Electric Powered Vehicles: Hype or the Future?

It's election year, so why wouldn't politicians jump on an easy target to benefit their agendas? Lets face it, life revolves around the all mighty dollar and, in too many cases, greed and power. We as consumers need to peel away the BS and discover for ourselves if electric powered vehicles could make sense for our future as individuals, and the country as a whole. Just like many of you, we had a lot of unanswered questions and really didn't know what to believe. It's not a matter of if, but a matter of when alternatives to oil will become absolutely critical.

In this article, we will begin to uncover the truth about electric powered vehicles. What does it actually cost to own and operate an electric powered vehicle? Are there potential cost savings to owning one? Is it truly environmentally friendly? How easy are they to live with? Even if you currently have no interest in owning an electric vehicle right now, this is something you should become aware of.

To start with, we'll briefly explain the four categories electric vehicles (EVs) typically fall into:

Hybrid Electric

A hybrid electric vehicle uses a battery-powered electric motor to supplement its traditional gas powered engine. The addition of the electric motor helps to reduce idling and enables the vehicle to operate with zero emissions at low speeds, typically below 40 miles per hour. At higher speeds, the gas powered engine drives the vehicle.

Plug-in Hybrid Electric Vehicles (PHEVs)

A plug-in hybrid vehicle is similar to a standard hybrid in that it combines an electric motor with a traditional gas powered engine. The difference is that it uses a larger battery which can be recharged by plugging the vehicle into an electrical outlet. As a result of this larger battery, the vehicle receives more power from electricity therefore increasing fuel economy.

Battery Electric Vehicles (BEVs)

These vehicles run solely on electricity and have no gas engines, therefore they produce zero tailpipe emissions. As a result of running exclusively on a battery, it is necessary to remain within the vehicle's range until the next available charge.

Extended-Range Electric Vehicles (ER-EVs)

Extended-range electric vehicles have both an electric motor and a gas powered generator. The electric motor directly propels the vehicle for the first 25 to 50 miles. After that, the on-board gasoline "generator" provides electricity to the motor. (The gas engine does not actually provide power to the wheels directly, instead it charges the battery which powers the electric motor.) This eliminates the need to drive within a limited range as it can continue to run on gasoline.

Our first EV test vehicle was a Chevy Volt, therefore will make a few references about our experiences with it in this article.

Available Incentives to Help Purchase an EV

The cost to design and build EVs are higher for manufacturers since it is still new technology and they do not have the benefit of economies of scale. In order to help entice consumers to make an EV purchase, the Federal Government and many state governments offer incentives. At the time this article was published, the Federal Government incentive for purchasing a new EV ranged from a $2,500 to $7,500 tax credit, depending on the type of EV and your filing status. There are also talks of increasing the Federal tax credit maximum amount to $10,000 and/or providing the credit at the time of purchase versus having to wait until you file your taxes as currently is the case.

A vehicle that has a potential tax credit is often marketed as having a flat tax credit amount, of course advertised as the maximum in the range. In reality, it's only worth that amount if your total Federal tax bill is as much or more for that fiscal year. In the case of the Volt which is eligible for up to a $7,500 tax credit, if you owe $6,000 in Federal income tax the year you purchase the car you'd receive a $6,000 benefit. The remaining difference can not be applied against the following year's taxes. If you opt to lease an EV car which qualifies for the incentive, the monetary credit stays with the leasing company who is the actual owner of the vehicle. Don't worry though, in most cases the tax credit has been factored into the cost of the lease so you are still gaining the benefit.

Many states also offer additional incentives from tax credits, such as Colorado's credit of up to $6,000, to other forms of incentives such as the state of California offering the sought-after car-pool lane access to EV owners. Knowing the potential incentives available to you can dramatically influence your purchasing decision.

Government Subsidies

It's interesting to hear how many people are so against the government subsidizing EVs. Yet, we don't hear much about how oil production is among the most heavily subsidized businesses in the U.S., despite being a hugely profitable industry. The International Energy Agency estimates that in 2009, governments worldwide spent $300 billion subsidizing fossil fuels. In 2010, that number grew to a staggering $409 billion. The U.S. alone averages approximately $4 billion per year in subsidies to the oil industry. Why doesn't this receive more attention? The reason is simple. "For the last decade, the oil industry has been one of the most powerful lobbying constituencies in Washington. It has spent nearly a billion dollars on federal lobbying since 1998." (1) What motivation would there be for affected political leaders to impart a change?

Charging Stations for Electric Vehicles

Level 1 - Most EVs purchased will come standard with a Level 1 charging station which you can simply plug into a standard 110 volt AC house outlet, just as you would a cell phone charger or coffee maker. This type of charger is also often referred to as an "over-night charging station" because of the amount of time it takes to fully charge a depleted battery. Keep in mind the bigger the battery, the more juice required when fully depleted. Using a level 1 charger, a Plug-in Hybrid may only take approximately 3 hours to fully charge, an Extended-Range Electric Vehicle 10 - 12 hours, whereas a Battery Electric Vehicle is approximately 17 hours from a depleted battery.

Level 2 - This type of charging station uses between a 208 through 240 volt AC outlet depending upon the station you purchase. It is important to look at the specific EV voltage the vehicle will accept in order to mate it with the appropriate charging station. If it will accept a 220 volt power supply, that is the same outlet typically used to run a clothes dryer. The benefit of a Level 2 charging station is the significant reduction of time to charge an EV. As an example, a Chevy Volt can be fully charged from a depleted battery in about 4 hours. The approximate one-time expense for the equipment and installation is typically between $1,500 - $2,000.

Level 3 - This is often called a "fast charge" station and uses a 480 volt DC power supply. The drawback is that these will not typically be available in residential areas because it's beyond the capabilities of existing transformers. This charging station will be seen most often in commercial areas. For EVs that are capable of using this type of charging station, it can charge a depleted battery in approximately 30 minutes.

To determine what level charging station is best for you, give some thought to when you would most likely be charging the battery and how much of a charge will be needed. If it'll be exclusively overnight, a Level 1 charging station might be just fine. Even now in it's relative infancy, you can buy a level 2 charging station from Best Buy, Lowes, Home Depot, Amazon and many other Big Box Outlets.

Where people can recharge their EV doesn't stop at home. Several cities are also beginning to install charging stations with many others conducting research on the viability of moving forward with the project. The city of Chicago has already begun installations of a massive project which promises to include 280 charging stations in the city and surrounding region within a year. Of these stations, there will be a total of 73 level three stations. California just recently announced that a minimum of 200 level 3 charging stations will be installed and in addition to creating the infrastructure for 10,000 plug-in units. Even with Hawaii having the highest electricity costs, they are adding over 200 public charging stations. This trend is continuing to grow contrary to reports of the EV demise. Imagine being at work, plugging in at no or little extra cost and having no fuel bill?

To find public charging stations in your area may take some time unless you're lucky. We were not able to find a single website that listed all charging stations in our area (Connecticut) and recommend you take the time to search multiple sites when you do your research. Like most technologies, this will evolve and potentially grow with time. Remember when the home computer was such a novelty?

Electricity's Not Free, So What Does it Actually Cost?

While driving an EV will reduce or potentially eliminate the need for purchasing gasoline, it still costs money to charge the battery. The factors that will impact the cost are how much power is required to charge your EV's battery, and what your electric provider's fees are. To give you a rough idea, using the U.S. average electric rates it costs approximately $1.50 to charge a fully depleted Chevy Volt battery. Living in CT where energy rates are towards the most expensive in the U.S., it still only cost us about $1.80 to fully charge a depleted Volt battery. Keep in mind that if you don't fully drain the battery, it won't require a full charge.

When evaluating electricity pricing, below are a few items we suggest you look into.

• Does your electric provider have a flat charge or a tiered rate structure based on the amount of electricity used?

• Do they utilize "smart grids" where your rate varies depending on consumption in the area (typically at night) results in a discounted price?

• Do they offer an EV owner discount?

• Are you able to change suppliers and if so, are there any that offer lower rates?

When looking at costs, be aware that there are additional fees other than just the electricity supply service charge. In our case there are also a delivery service charges representing a Generation service charge, Transmission charge, Distribution charge, CTA charge, FMCC delivery charge, and a combined public benefit charge. Enough different charges?

Saving the Planet! But Is Electricity Really Green?

A selling point many people make about transitioning to electric powered vehicles is how environmentally friendly they are. While it's true that EVs reduce tailpipe emissions or depending on the type of EV, even eliminate them completely, there's more to it. To really determine if an EV will truly be Green where you'll be using it most, take a look at how your electricity is being produced.

Most of the U.S.'s electricity is produced domestically and is often times delivered from a mix of power plants including coal, nuclear, natural gas, petroleum, and renewable sources. The type of power plants vary by region, therefore it's important to examine these vehicles on a regional basis in order to better understand their environmental impact.

The time of day the EV will be recharged also plays a role on how Green the electricity is. The generation mix at the time of charging is different based on the time of day, time of year, geographic region, and load patterns. Sharp summer peaks are caused by air conditioning demand, although such peaks typically occur in the afternoon. Overnight when businesses are closed, demand is at its lowest. As a result of this, the power plants that are most expensive to operate and easiest to power down such as old coal and natural gas, get turned off. Other plants that have less expensive operating costs and are harder to turn off such as wind, hydroelectric and nuclear, are kept running.

Even if you live in an area where the production of electricity is not typically produced using clean methods, you might have the option to change it to a clean source. Regardless of where you live, this is worth looking into. While we have not yet purchased an EV, it did spur us to look into the different alternative energy sources. Our current supplier charges 8.25 cents per kW and uses a mix of various energy sources including coal. Our state allows us the option to use another supplier, and we found a 100% renewable energy source (primarily wind in our case) that has a rate of 7.99 cents per kW. Yes, that same company also offers coal produced electricity at a lower rate of 7.39 cents per kW, but the switch to clean energy still provides a savings.

According to electric vehicle manufacturers and other sources we saw, the impact of producing the lithium-ion battery is less than or equal to the impact of producing a similar gas car. More than 95% of the battery materials can be recycled or reused with minimal environmental impact. The minerals used in these types of batteries are expensive, so it's not hard to imagine companies being especially motivated to find methods of reusing them.

Reduce Dependence on Foreign Oil

Every President dating back to Nixon has stated the need to formulate methods to control our energy future and reduce dependence on foreign oil. The U.S. has around 2.5% of the world's oil reserves but uses about 20%. While those statistics vary depending upon the source, it's clear that we are heavily dependent upon foreign sources of oil. Approximately 70% of America's daily oil consumption is currently used in transportation, therefore this is a major area that deserves attention. As other countries continue to increase their oil reserve demand, gas prices will continue to rise. In 2010, China alone added approximately 10 million cars to the road. President Obama's All In energy policy (one that Bush advocated and that McCain supported as well) attempts to reduce our dependency on oil. This is not a left or right political issue nor is it something that can be solved over night. It is however, an issue that we need to address together as a nation. This is yet another benefit of electric vehicles and reasoning of why government (Federal and state) is providing incentives.

Summary

We recognize this article only touches upon the vast information available on this topic. What we hope is that it will spur some additional thought about EVs, and maybe even just related environmental concerns in general. Why not go test drive one yourself?

Driving isn't just about getting from point A to point B - it's about the experience a vehicle imparts along that journey. As automotive enthusiasts, we won't sacrifice everything we love in a vehicle for function. Yet sometimes our practical side demands we drive cars that can haul kids, luggage, a boat, or maybe just our golf clubs.

We review vehicles from sports cars to tow vehicles and complete our testing on real roads, with real kids, real luggage or even real trailered loads. We focus on what each vehicle is designed to do, then judge whether it delivers on those claims and describe the emotional experience of driving the car.

Nissan Future Models Go Electric

Electric cars... a few decades ago the mere thought of a mass produced battery powered car would've been laughable, but then again a century ago the thought of a man walking on the moon would've been unthinkable. Thanks to sheer dedication and passion for innovation, companies like Nissan strive to make the impossible, possible and they won't give up until they do.

It might surprise many to know that Nissan's electric vehicle research dates back as far as the 1940's when it released its first electric vehicle in 1947, the Tama EV which was equipped with lead batteries. In 1997 it released the Prairie Joy EV and then in 2005 the Nissan Pivo followed by the Pivo 2. With various limitations such as short cruising ranges none of these vehicles really took flight. That was until 2009 when Nissan announced its latest and so far greatest EV yet, the all-electric, 5-seater Nissan LEAF.

In 2010 the LEAF was launched in Japan, Europe and the United States and received a positive response from owners and the motoring industry alike earning it the coveted 2011 World Car of the Year title along with many other international awards.

Though the Nissan LEAF might not produce sports car performance and SUV capability it delivers ample power and torque to get the driver from A to B and back. It's 80kW and 280Nm electric motor lets you travel distances of up to 160km on one charge while it's capable of reaching a maximum speed of 145km/h. And charging it is effortless and hassle-free. The Nissan LEAF is powered by a lithium-ion battery and can be plugged into your regular household socket, while it takes around 8 hours to fully charge.

This Nissan future model isn't just 100% electric and fully rechargeable, but also promises low fuel consumption and zero gas emissions making it likely the greenest car on the planet today. Though we often find it hard to quantify the reduction in damage on the planet that fewer emissions will achieve, Nissan explained it in simple terms in a recent update. If the LEAF units already sold were powered by gasoline, it would've emitted 17,633 tons of CO2 and for a forest to process that amount of CO2 it would require 1,261,643 trees. When looking at the numbers, EVs do seem like the logical move forward for the motoring industry. And more future Nissan models are expected to follow in the LEAF's emission-free tracks.

The author occasionally writes articles on future motoring topics that include reviews of the Nissan LEAF and other electric vehicles and how it is changing the future of driving.

How To Get Great Gas Mileage Without An Electric Vehicle

ByTom Clay

With gas prices on the rise you may consider buying a new electric or hybrid vehicle. You can still save money and conserve energy using your old car if you follow some simple tricks to get the best gas mileage out of your car.

As electric vehicles are just making its way into the United States' markets, with only few states being offered an opportunity to invest in an electric car, other means of conserving energy needs to be revealed. Listed below are the top three tips on great gas mileage without an electric vehicle:

1) Be a responsible and smart driver. Don't drive aggressively by speeding and getting into aggressive behaviors with other drivers. Follow the designated speed limits. The speed limits are not only designed for your safety, but can also aid you in conserving fuel energy by driving at lower speeds. The lower the speed driven, the less fuel is used, thus increasing the amount of miles a driver can reach per gallon.

Being an aggressive driver by pressing on the gas pedal quickly and with great force causes a surge of gas to be released to power the vehicle forward. Slowly engaging the vehicle forward by pressing on the gas pedal at a steady pace from any complete stop, uses less fuel energy.

Opting to use a vehicle's cruise control option also is a way to deter excessive pressing on the gas pedal or driving above the set speed limits. Using the cruise control option is great for long drives at a steady pace, such as on long highway trips. This helps maintain the vehicle at a constant speed with no surges of fuel.

2) Don't let a car idle for longer than 30 seconds. Many drivers have this habit of letting a car idle for long periods as they wait in bank lines, fast-food drive through lines, or wait for a passenger they are picking up. It is best to turn off the vehicle to save fuel energy. Many drivers believe that idling a car, rather than shutting a car off and restarting it again saves energy, but that is not true. If a wait will be longer than 30 seconds, it is always better to turn off the vehicle. If it's a hot day and as you wait you want to remain cool with running the car's air conditioning, think twice. It's better to roll down the windows and breathe some fresh air.

3) Follow a regular vehicle maintenance plan. Vehicles usually come with a maintenance guide from the dealership. This guide shows when vehicles should receive services, either by mileage or by a specific time period. Another option is to switch to energy saving motor oil, which has been shown to give a vehicle better performance. With regular maintenance, a vehicle runs smoothly and gets better gas mileage. Maintenance includes keeping the vehicle's tires well-inflated to the manufacturer's recommendations.

These tips can save a vehicle owner from unnecessary fuel expenses. Just taking some simple steps to maintain your vehicle and drive smartly can make any car more fuel efficient.
