2013 Ford Focus Electric


When an automaker makes the decision to enter the electric car market it has two choices: Spend hundreds of millions designing, developing and tooling the plants to build an all-new car, like Nissan did with the Leaf or, reduce the risk and cost by replacing the drivetrain of an existing gas-powered vehicle with an electric one. This latter choice was the one Ford went with for its newly launched Focus Electric.
Like Mitsubishi did with its i-MiEV, Ford dipped its toes in the EV waters opted to transform an existing car into an e-car and chose the Focus hatchback compact car for its first pure electric car. This means the Electric is built on the same assembly line as the gasoline Focus in Wayne, Michigan. This offers Ford the option of increasing or decreasing EV production depending on demand.
In the past Ford has said it wants its hybrids, plug-in hybrids, and electric cars to be more than a niche, and that it’s about affordable transportation for the masses. With the Focus Electric, the automaker is at least on the “verge” of being affordable. The 2013 Focus Electric is priced at $39,200 – about $9,000 over the present average American new car price – and before the $7,500 federal or state tax incentives are potentially deducted.
However, a part of affordability has to do with fuel economy, and this is where the Focus Electric really shines given it does not even burn “fuel” in the traditional sense, but uses an efficient electric powertrain. To help consumers compare fuel efficiency between gasoline or diesel cars and electric cars, the EPA has developed a formula called miles per gallon equivalent (MPGe). Focus Electric has an MPGe rating of 110 City/99 Highway and 105 Combined.
Ford introduced the electric version of the new Focus first in California, New York and New Jersey – before expanding distribution to 19 additional markets. Those 19 markets include Atlanta, Austin, Boston, Chicago, Denver, Detroit, Houston, Los Angeles, New York, Orlando, Phoenix, Portland, Raleigh Durham, Richmond, San Diego, San Francisco, Seattle, Tucson and Washington, D.C. The rest of the U.S. will have to wait a while.

Powertrain Details

To convert the gas-powered Focus to an EV, the aforementioned electric motor replaces a gasoline engine and an L-shaped battery pack is placed under the rear seat and between the rear wheels. Directing power from the electric motor to the front wheels is a simple, direct drive single-speed transmission that takes the place of the standard transmission.
The water-cooled alternating current, 107-kilowatt synchronous permanent magnetic motor generates 143 horsepower and a generous 184 pounds-feet of torque at 0 rpm – yes, “0 rpm” is theoretical given no work is actually taking place, and some editors balk at this, and write in “1 rpm,” but you get the point. The energy is 100-percent from the get-go.
2013 Ford Focus Electric
And from said get-go, the Focus Electric’s estimated 0 to 60 mph takes the Focus EV around 9.5 seconds, and its top speed is a modest 84 mph.
Feeding the motor is a 23-kilowatt-hour lithium-ion battery pack with more than 17 kWh available in the charge-discharge cycle. The battery pack employs an actively liquid cooled and heated system that allows stable battery operation by maintaining an optimal range of temperature.
While driving, regenerative braking recovers more than 95 percent of the energy normally lost and stores it in the battery. Every time the car coasts or brakes are applied, the electric motor acts as an electric generator and coverts the energy to electricity.

Getting Charged Up


 Ford pulled off a one-upsmanship on the Nissan Leaf by equipping the Focus with a 6.6-kW on-board charger. It adds about 20 miles of driving range for every hour of charging, instead of 10 miles for each hour supplied by the Leaf’s 3.3-kW charger. Filling the battery with electrons when empty takes about four hours using Ford’s 240-volt Level 2 home recharging unit versus the Leaf’s seven to 10 hours. However, charge time of around 20 hours using a standard 120-volt plug receptacle is essentially the same as the Leaf’s.
Ford developed with Leviton its home charging station, and priced it at $1,495, including normal installation (normal meaning a home already properly wired for its voltage and amperage). And, unlike other units, the charging station can simply be unplugged if you relocate – electrician not required to remove it.
For hardcore, and sufficiently well-healed, greenies, Ford has teamed up with solar system maker SunPower. A 2.5-kilowatt rooftop solar panel system will provide Focus Electric owners enough renewable energy production to offset the energy used for charging. The solar panels produce an average of 3,000 kilowatt hours of electricity annually, enough output to accommodate a customer who drives 12,000 miles a year. Assuming “normal’ installation, the installed cost is $10,000 after federal tax credits.

Styling

An all-new Ford Focus was introduced in late 201l as a 2012 model. Designed by Ford’s European arm, it follows the company’s “kinetic” styling themes, which the automaker calls an “energy in motion” look. It’s an edgy, adventurous exterior characterized by a disport ensemble of swoops and wedges.
2013 Ford Focus Electric
Like the standard Focus hatchback, the Electric has an athletic profile that features a raked roofline. Tires mounted on 17-inch aluminum wheels fill the wheel wells, giving the car an “it’s time to rock ’n roll” performance look. The big difference between the two is up front. Rather than the gas-powered Focus’s single bar grille and almost menacing looking gaping mouth flanked by bold triangle intakes, the Electric has a more stately, Aston Martin-like design with narrow horizontal crossbars. On either side of the new grille, HID headlamps sweep gracefully up and into muscular front fenders. The tail end of the Focus is quite distinctive with a large rear spoiler and giant taillamps that wrap around the corners.

In The Tech-Rich Cabin

Interior quality is a giant leap from the previous generation Focus. Material quality is arguably the best in the small car class, heavy on soft touch surfaces with an astute mix of stout plastic panels. All are nicely grained or show a stylish matte finish, and the switchgear features a no-slip shape or coating. The cabin has a spacious feeling, though backseat legroom is tight.
2013 Ford Focus Electric
The Electric’s dashboard mimics the standard Focus and is designed for those comfortable using all manner of mobile infotainment devices – potentially a turn-off for some buyers. The four-spoke steering wheel is the same, including a pair of buttons on two spokes along with cruise control operation and Ford’s SYNC, the integrated communications and entertainment system.
The instrument cluster has a centrally mounted speedometer with a pair of color displays on either side. The right screen displays climate, entertainment and navigation as well as a driving efficiency graphic of blue butterflies. The left screen delivers relevant EV information such as available range and battery state of charge.
2013 Ford Focus Electric
Mounted in the center console is an eight-inch screen that features MyFord Touch infotainment system. It fetches up audio, navigation, phone and climate controls that some reviewers rave about while others say that at best, the almost knob-less and button-less interface is confusing and frustrating to operate.
What’s not confusing to operate is the gear shifter. Rather than some weird gear selections, the Focus Electric has the standard PRNDL—park, reverse, neutral, drive and low—positions that everyone is familiar with.
But wait, there’s more technology. The standard MyFord Mobile app, available for iOS, Android, and Blackberry, helps EV drivers locate local charging stations, plan trips, view current battery status and manage remote charging. For the social-connected crowd, a gaming feature lets owners share accomplishments on Facebook and Twitter.
2013 Ford Focus Electric
Basically, the Focus Electric comes standard with the same trim level as the top-of-line Titanium edition of the gasoline Focus, meaning that it is thoroughly appointed. Standard features include: Intelligent Access with push-button start; power locks, windows and outside mirrors; dual-zone climate controls; heated front seats; leather-wrapped steering wheel; Sony nine-speaker audio system; satellite and HD radio; ambient lighting; and a rear camera with rear parking sensor. The only options are leather seats and two paint colors.
When it comes to safety, the Focus Electric has all the biggies: Anti-lock brakes, stability control, traction control, dual front airbags, drive and front passenger side-protection airbags and curtain side airbags.

Driving The Focus Electric

When the 2012 Focus arrived, auto critics penned high praise about its ride, handling and braking characteristics. Since the Electric version has the same structure and independent front and rear suspension, it’s no surprise that many of these same reviewers give the EV high marks. Road and Track commented, “Apart from its EV quietness, the car’s road-going demeanor does little to set it apart from its gasoline-fueled counterpart.” And Automobile magazine remarked, “With the independent multilink rear suspension, no untoward body motions are observed. The ride is perfectly acceptable, thanks to recalibrations made necessary by the extra weight (of the batteries).”
A quiet ride is synonymous with the electric car driving experience as noted by the New York Times’ reviewer, “Battery-powered cars are intrinsically quiet, the motor sound falling between a whir and a whisper. But the Focus is deep-space silent, the quietest of the many electric cars I’ve driven.”
2013 Ford Focus Electric
Mark Vaughn, AutoWeek’s west coast editor and an i-MiEV owner, said, “The Focus Electric is the quietest EV we’ve driven yet. Ford spent time and energy adding sound insulation throughout the vehicle and damping down everything that might disturb its compact serenity. You won’t hear gears whining, clicks clacking or switches switching.” He added, “Stomp on the throttle, and it’s hard to feel any torque steer at all.”

The EV For You?

If you want a car that doesn’t run on liquid fuels, the Focus Electric has few competitors. That includes the funky styled Mitsubishi i-MiEV, which is smaller than the Focus, has a shorter driving range and longer charging time, and starts at $29,125. Arguably, the electric $39,145 Chevy Volt with gasoline-powered generator backup could be an alternate option, although not if you never want to burn gas. It is a shorter range EV – the government rates it at 38 miles all-electric range – and the gasoline engine kicks on when the usable electrons are depleted. If kept within electric range, it is competitively frugal to operate as other EVs.
Nissan’s 2012 Leaf is the actually closest comparable EV. The Leaf is less expensive than the Ford with the hard-to-find base SV model starting at $35,200, but the more popular SL model starts at $37,250, just $1,950 less than Focus Electric.
The Focus Electric and Leaf have close EPA ratings for both driving range and efficiency: The Leaf is rated at 73 miles of driving range, with a rating of 99 MPGe (miles-per-gallon equivalent), The Focus Electric is slightly better on both counts, with 76 miles of range and a 105 MPGe rating.
The Focus EV has a decided advantage when it comes to battery charge time. While both vehicles require around 20 hours to charge from a standard household 120-volt outlet, the Focus Electric needs just four hours charge from a 240-volt outlet versus the Leaf’s charge time with the same voltage. The Leaf does offer a DC quick-charging capability – not available on the Focus – that can recharge the battery pack to 80-percent capacity in around 30 minutes, but few such charging stations exist yet.
Where the Leaf differs also from the Ford is it was designed without an active liquid thermal management system – partially accounting for its lower cost. Nissan has said thermal management was deemed not necessary for the Leaf’s battery pack design.
2013 Ford Focus Electric
The Leaf has however experienced a minor controversy all year as to whether lack of liquid cooling in particular leads to heat-induced premature failure in a few of the states in which it was first launched beginning late 2010, and these also are among America’s hottest states. Nissan has denied any inherent design flaw and commissioned an independent panel to investigate further.
Further complicating the choice is a September report in which Nissan’s CEO was quoted as saying pending 2013 model year Leafs are being equipped with a larger battery with as-of-yet unreported capacity increase over its first-generation 24 kwh. This is expected to increase range – other reports put it at possibly 25 percent or so. Therefore, it’s a series of pros and cons comparing the 2012 Leaf, and even more so, the believed-pending 2013 Leaf, to Ford’s first-generation thermally managed 23-kwh Focus Electric.
Both the Focus Electric and Leaf will whiz by gas stations while producing zero emissions, and most owners of either car will recoup at least a few thousand dollars of the premium from lower fuel and maintenance costs.
So, which of the two battery electric cars are for you?
Another final decider between the Focus Electric and Leaf could be styling. For those that don’t want to show off their environmental leanings, the Focus EV is designed for the generic aisle of the dealership. Its styling is edgy, sporty, decidedly European and its green credentials are incognito. The Leaf, on the other hand, is a dedicated design with distinctive styling – no upfront grille, bulging headlights, wide rear end and odd proportions combined say, “I’m a green car.”
Tough choice, huh? But if you want to drive one of the sharpest-looking cars on the road while smiling to yourself because you have no personal connection to OPEC, the Focus Electric is the EV for you.

Electric Vehicles (EVs)


Electric vehicles (EVs) are propelled by an electric motor (or motors) powered by rechargeable battery packs. EVs have several advantages over vehicles with internal combustion engines (ICEs):
  • Energy efficient. Electric vehicles convert about 59–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17–21% of the energy stored in gasoline to power at the wheels.*
  • Environmentally friendly. EVs emit no tailpipe pollutants, although the power plant producing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind-powered plants causes no air pollutants.
  • Performance benefits. Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than ICEs.
  • Reduce energy dependence. Electricity is a domestic energy source.
EVs do, however, face significant battery-related challenges:

EV recharging
  • Driving range. Most EVs can only go about 100–200 miles before recharging—gasoline vehicles can go over 300 miles before refueling.
  • Recharge time. Fully recharging the battery pack can take 4 to 8 hours. Even a "quick charge" to 80% capacity can take 30 min.
  • Battery cost: The large battery packs are expensive and may need to be replaced one or more times.
  • Bulk & weight: Battery packs are heavy and take up considerable vehicle space.
However, researchers are working on improved battery technologies to increase driving range and decrease recharging time, weight, and cost. These factors will ultimately determine the future of EVs.


Note: EV energy use estimated by ORNL as follows:
  • Electric motor efficiency—including inverter and gear reduction losses—assumed to be 76.4–80.2%, using estimates from Miller et. al. (SAE 2011-01-0887) and adjusting downward by 4% for parasitic losses.
  • Battery and battery charger efficiency are assumed to total 81% (roughly 90% each) based in part on estimates from published studies (Chae et. al., 2011; Gautam et. al., 2011).

20090728 - Nissan's Electric Car Prototype: Rough Draft of the Car of the Future?


Nissan Expects to Produce 150,000 Electric Cars by 2012

On August 2nd, Nissan will unveil its new electric car in Japan, but in the meantime, we can have a look at the prototype that Nissan has been using to test their electric drivetrain. It's based on the Nissan Versa, but the gasoline engine has been replaced by an electric motor developed in-house. It has a power rating of 80kW/280Nm (107 horsepower/206 pound-feet of torque). That's a lot of torque for a car this size. Read on for more technical details and many more photos.


24kWh Li-Ion Battery in the Car's Floor

The 24kWh battery is based on a lithium-ion chemistry, and it is located under the vehicle floor for "more efficient packaging". This has three main benefits that I can see: 1) A lower center of gravity, 2) it doesn't reduce cabin or cargo space, and 3) Nissan says that the "battery layout also allows smooth underfloor air-flow which helps reduce drag."

There are images of the battery layout below.

Using the Onboard Computer to Show Battery Range, Charging Stations

Nissan also promises that its EV will be a very connected car, with technology at work to reduce "range anxiety". The electric car's navigation computer can show the driver, at the touch of a button, the driving radius within range under the current battery charge, and the system can also calculate if the current destination is within that range. No more guesswork.

The range is about 100 miles (160 km), but Nissan says that regenerative braking can help extend that. It depends on driving conditions (city vs. highway).

The onboard computer will be able to download information about nearby charging stations, with detailed information about each.
 A Quiet Drive

Nissan writes: "High durability is achieved by employing an additional frame for the battery pack to significantly improve the rigidity of the platform. The combination of a high rigidity platform and electric powertrain minimizes vibration and external sounds to produce a quiet and pleasing drive."


 Timing the Charging of the Battery, the Car can Text You When Fully Charged

Another clever trick: The Nissan EV can be set to run the air conditioner at a certain time while still plugged in. What this means is that if you know you're going to drive at, say, noon. You can set the car to cool the cabin at 11:50 so that when you drive away, you don't have to run the A/C as much, extending the range.
The car can also be set to recharge at certain times of day when electricity rates are lower (for those with time-of-use rates).
The driver can monitor the state-of-charge of the EV via an online website and a cellular phone. For example, when the battery is fully charged, a message alert is sent to the cellular phone. Additional remote control functions range from switching the charging system ON/OFF or setting the air-conditioner timer.

Nissan's CEO, Carlos Ghosn, seems to be one of the driving force behind Nissan's electric car program, and he has forcefully expressed his passion for EVs many times (here, here, and here). This is a contrast with the lack of excitement about EVs at Toyota's management level...

20120809 - Mobil listrik Piev dari Pindad sedot pengunjung RITech Expo


Bandung (ANTARA News) - Mobil listrik buatan PT Pindad bernama Piev (Pindad Electronic Vehicle) yang dipajang di RITech Expo 2012 di Sasana Budaya Ganesha, Bandung menyedot perhatian pengunjung, Kamis.

Mobil listrik Pindad tepat di pintu keluar gedung itu berada di sebelah mobil-mobil listrik lainnya dari lembaga lain.

Menurut staf Product Development PT Pindad Firmansyah, dibanding mobil-mobil listrik lainnya yang dipajang di pameran itu, Piev yang baru dikeluarkan pada 2012 ini memiliki kelebihan yakni motor listriknya dibuat sendiri oleh Pindad, termasuk baterainya buatan dalam negeri sehingga 95 persen mobil ini buatan dalam negeri.

Perbedaan mendasar antara mobil listrik dan mobil konvensional (BBM) terletak pada sistem penggeraknya yang konsepnya 100 persen berbeda, jika mobil konvensional menggunakan engine, maka mobil listrik menggunakan motor listrik, namun motor listrik selama ini masih diimpor.

"Tapi ini kami buat sendiri. Dimensi motor listriknya hanya 60mm lebarnya dan 200mm diameternya, yang beratnya hanya 18 km, cukup kecil, tapi dayanya besar sampai 25 ribu Watt (25 kW). Bandingkan dengan pompa air listrik di rumah yang dayanya cuma 125-500 Watt tapi secara fisik besar," kata Firmansyah.

Motor listrik buatan Pindad ini memiliki tegangan 40 V, torsi 40 Nm, dengan putaran maksimal 5.000 RPM dengan efisiensi 95 persen.

"Motor tersebut dihubungkan dengan kontrol buatan Schneider Jerman yang dalam waktu dekat akan juga dibuat di dalam negeri," ujarnya.

Baterainya buatan dalam negeri (kerja sama pindad dan NiPress), menggunakan batere Cadmium (batere basah) sebanyak 40 buah.

"Batere ini makan tempat, tidak seperti batere Lithium (kering) dan kecepatannya juga hanya 80 km/jam dengan daya jelajah hanya 80 km untuk di-charge kembali," katanya sambil menunjukkan bagian belakang kendaraan Piev yang seluruhnya dipenuhi baterai.

Soal baterai , pihaknya memang masih akan meriset, karena itu untuk saat ini jika tak mau memakan tempat, baterai  Cadmium bisa ditukar dengan Lithium yang masih harus diimpor dari China.

Firmansyah mengatakan bodi kendaraan sudah seluruhnya bisa dibuat di dalam negeri.
