Charged with Electric Vehicle News and Views
The car's futuristic look and feel, as well as its energy-saving production, will probably be the most important factors in convincing drivers that it is stylish to drive green. 
This time next week the world's most energy efficient electric cars will be hitting speeds of up to 130 km/h (81 mph) as they race 3,000 km (1,865 Miles) coast to coast across the Australian Outback contesting the Bridgestone World Solar Challenge.
The outright contenders for line honours will come from the big budget single seater aerodynamic vehicles of the Schneider Electric Challenger Class. The only external energy source allowed during the race is solar irradiation received by a maximum of either 3 square meters of high-efficiency (22.5%+), triple-junction gallium arsenide (GaAs) solar cells or 6 square meters of silicon based solar cells with less than 22.5% efficiency. The solar array is paired with a maximum on-board energy storage capacity of 5 kw/h to assist with energy use strategy, hills, clouds or extra acceleration for overtaking.
To have a good chance to win each car has to 1) Collect as much solar energy as possible and 2) Use as little energy as possible. This means special attention needs to be applied to the efficiency of transferring electrical energy to the wheels and minimising friction from aerodynamic drag and rolling resistance which is affected by vehicle weight amongst other things.
To achieve the electrical efficiency goal, every Bridgestone World Solar Challenge winner since at least 1999 has used a direct drive in-wheel motor to propel the vehicle. Direct drive eliminates mechanical transmission losses that can be as much as 20%.
Solar cars use very low rolling resistance tires that are specially designed for this race with a rolling resistance ten times less than an average road car. With the rolling resistance of a cars tyres accounting for roughly 20% of all energy used, tyres can account for up to one in every five tanks of fuel in a regular road car. Vehicle weight is also kept extremely low with extensive use of carbon fiber, again to minimise rolling resistance.
Tokai Challenger in 2011 won with an average speed of 91.54 km/h (56 mph). With such high average speeds combined with the physics of air resistance being proportional to the square of speed, aerodynamic drag is the main source of losses on a solar race car. Much design effort is invested in CFD computer simulation, scale and full size wind tunnel testing. The best solar race cars achieve a drag coefficient as low as 0.07 (Nuna 3 – which holds the record for highest average winning speed @ 102.8 km/h) where a road car ranges from 0.24 (Tesla Model S) to 0.35 (Toyota Land Cruiser).
It is the chase of maximum aerodynamic efficiency that has lead to the race winning dominance of “coffee table” type vehicle designs which brings up the question of how practical can a solar-powered vehicles be? The 2013 Bridgestone World Solar Challenge sees the introduction of the Michelin Cruiser Class which is not focused on speed but practicality, with the ultimate goal of entrants being able to meet the requirements for road registration. Cruiser Class cars must seat a minimum of two people and will be allowed over-night battery charging at select locations.
While the Michelin cruiser class aligns solar race car design more closely with road car requirements, if the limitations of having the solar panels on the vehicle itself are removed, powering a regular road going EV with solar power is an affordable reality today!
Tesla Motors recently launched a network of solar powered superchargers capable of charging their Model S to 320 km of range in 30 minutes. Even a modest 1.5 kw residential roof-top PV solar system generates enough energy to power a commuter EV like a Nissan Leaf for more than average annual mileage. In fact, displacing the cost of petrol instead of grid power will reduce the break even time on a roof-top PV installation to just a few months.
This year’s Bridgestone World Solar Challenge is held from 6th – 13th October. If you can’t make it to Darwin or Adelaide, you can follow the race on Twitter via @tsport100 or @WorldSolarChlg.

The SAE International DC “Combo” Fast Charge station installation at the Fashion Valley Mall in San Diego is a milestone for plug-in electric vehicles – the first public installation in the U.S. of an industry-coordinated standard for fast charging of plug-in electric vehicles.
The Chevrolet Spark EV, available in California and Oregon, will be the first EV in the U.S. to offer the SAE International fast-charge connector as a vehicle option starting in late December.
“The launch of these new charge stations will help improve the convenience and adoption of electric vehicles because they dramatically reduce the charge time,” said Pamela Fletcher, executive chief engineer of electrified vehicles at General Motors. “The SAE Combo DC fast charge stations are the result of EV industry collaboration to help customers benefit from available public infrastructure.”
The new combined AC and DC charging, or combo, connector is accessible via a single charge port on the vehicle and allows electricity to flow at a faster rate, making EVs more convenient for longer trips and for EV owners who may lack convenient access to overnight home charging.
“San Diego Gas & Electric applauds the collaborative efforts it took to make San Diego home to the world’s first retail SAE DC fast charge station,” said Lee Krevat, director of smart grid and clean transportation for the utility. “Our local drivers that have vehicles equipped with this charging system connector will be the true beneficiaries of this technology.”
Many major automakers including GM, Ford, Chrysler, BMW, Daimler, Volkswagen, Audi and Porsche have announced they will adopt the SAE combo fast charge connector standard. Earlier, many of the world’s major automakers had adopted the SAE’s 120V/240V AC connector standard to assure plug-in vehicles could access all charging infrastructure regardless of vehicle make or model.
AOL's Translogic take the NISMO RC for a spin and interview NISMO President Shoichi Miyatani at the recent Nissan 360 media event.
Nissan is selling more LEAFs than ever before and is the lead sponsor of National Plug-In Day in 2013.
With the day being about plugging in to charge up, Nissan pointed some video cameras at the company's EV quick charger, stationed in front of Nissan Americas headquarters in Nashville, Tenn. to see who is stopping in to charge and go.
California has a goal of having 1.5 million electric vehicles on its roads by 2025.
Gov. Jerry Brown on Monday toured an electric car fleet that included Tesla, BMW and Honda as part of a meeting with other car manufacturers and private companies. The meeting was held at San Francisco's Exploratorium and discussed the future of the electric car.
Brown said he will sign two pieces of legislation continuing incentives for purchasing electric cars.
Mitsubishi Motors Corporation remains convinced of the virtues of motor sports to improve the breed and whilst the glorious days of the Dakar Rally and the World Rally Championship are long gone for Mitsubishi, the achievements of the innovative i-MiEV Evo electric monoposto racer at Pikes Peak still prove the point – especially for pioneering technologies.
In the case of the bigger SUV/crossover Outlander, cross country was deemed better suited – more so as it would be an unusual showcase for Outlander PHEV and its unique Plug-in Hybrid Electric drivetrain.
A pre-production Outlander PHEV was entered in the 2013 Asia Cross Country Rally (or “AXCR”) which took place August 10th – 16th between Thailand and Laos, post-event celebrations starting today in Japan.
An officially FIA sanctioned race, the AXCR is an Asian take at a Dakar-type of extreme cross country rallying, which started this year from Pattaya and finished in Pakse, in the southern part of Laos.
Over 6 days, competitors drove over 2,000km on various road surfaces and conditions including mountain roads, muddy jungle, river crossing, etc,…, making it a true challenge in terms of driving performance and endurance.
A reliable choice
Out of a total of 20 entries in the four-wheeled category (of which 19 finished), the Outlander PHEV attracted quite some attention as it was the only plug-in hybrid vehicle to participate, most competitors behind heavy-duty Diesel-powered pickup trucks.
Entered by a private team (“Two and Four Motor Sports”), backed by Mitsubishi Motors, the sole Outlander PHEV finished 17th overall with no failure: quite a success for what was essentially a standard car – including the Twin Motor 4WD plug-in hybrid electric drivetrain, as well as the Super All Wheel Control (S-AWC) system – the only modifications being the regular cross-country racing routine of upgraded shock absorbers and springs, roll cage, underfloor protection, exhaust and snorkel duct, etc,…
World markets
Completing such a tough rally with no problem whatesoever confirmed the durability as well as the dynamic performance of Outlander PHEV just a few months before it starts its commercial career in world markets.
Mitsubishi will launch Outlander PHEV sequentially, starting with selected PHEV markets (The Netherlands, Nordic countries, etc,…) from October 2013 onwards.
The other European markets will gradually follow from November 2013 to Q1 2014.
Volkswagen really don't seem to 'get it'! The chairman of the supervisory board at Volkswagen Group, Ferdinand Piëch, revealed during a lecture at the Vienna University of Technology that VW are working on a racing version of the XL1 to be powered by a 1.2 Liter two cylinder Ducati 1199 Panigale R superbike engine.
Instead of ditching the XL1's 47 hp two-cylinder diesel engine and showcasing their recently launched EV strategy by installing a high performance 200 kw electric motor into the low drag carbon fiber XL1 chassis, something that might give a Tesla Roadster a runs for it's money, VW decide to stay old school and take a huge step backwards by off-loading the XL1's entire hybrid system to bring the XL Sport's down to 795 kg.
Not only does the 190 hp / 123 Nm Ducati motorcycle engine has less power and torque than a standard Tesla Roaster, and significantly less than a Roadster Sport (300 hp / 400 Nm) but the V-Twin's peak torque is at 9,000 rpm instead of from 0 rpm like the Tesla. While the XL Sport may have a weight advantage over a Roadster (1,235 kg), it'll still be significantly slower 0-100 km/h and will be about as technically advanced as a motorcycle engine powered Locost Britsh kit car, or even the Piontek Sportech kit car chassis the Tesla powertrain was originally developed in.
“We are planning to have a plug-in hybrid in each and every model series,” BMW’s head of production for large vehicles, Peter Wolf, told motoring.com.au this week. “So far we have the 3, 5 and 7 Series as full hybrids, and at the other end of the bookshelf the i3 and the i8. We are planning to work on that with the X5 eDrive, but at this stage, the plug-in is a completely new concept, and the battery is very specific [to the X5].”
BMW showed off the X5 eDrive concept at the recent Frankfurt motor show, and officially launched it this week. The large SAV (not an SUV, mind you) has an intelligent all-wheel-drive system, a four-cylinder gas engine, a 70 kW electric motor and a 19-mile electric range.
Wolf said that the X5 eDrive is close to production-ready, but wouldn’t give an actual date: “We can’t tell [you] anything about what is the start of production, but we are working on such a concept [and] we are very far [along]. But it’s not a part of next year.”

Sumitomo Metal Mining will invest ¥4.8 billion (US$48 million) to boost its production capacity of lithium nickel oxide (LiNiO2) from the current 300 tons per month to 850 tons to meet anticipated increased Li-ion cell production by Panasonic to meet the growing demand for Tesla Model S EVs.
Sumitomo successfully developed its high-performance lithium nickel oxide for cathode materials in collaboration with Panasonic Corporation and is now supplying this material to that company, which uses it to make the cylindrical lithium-ion batteries which are adopted in the electric powertrains used by Tesla.
Tesla commenced deliveries of its award-winning Model S sedan in the US in June 2012. With Model S deliveries now underway in Europe and slated to begin in Asia, including Japan and Australia, in the spring of 2014, Panasonic is planning to increase production of its lithium-ion batteries.
To respond to this expansion of the market for automotive rechargeable batteries, Sumitomo will expand its production facilities for lithium nickel oxide at its Isoura Plant in Niihama City, Ehime Prefecture. Expansion work is to get under way in October, with completion scheduled for June 2014.
Sumitomo says it is pursuing aggressive development and stable supply capability in cathode materials, leveraging its ability to produce nickel in-house. Going forward, Sumitomo intends to further strengthen its operations in materials for energy and environmentally related applications.
