Charged with Electric Vehicle News and Views
The "2013 Ene-1 GP SUZUKA" next-generation electric energy car event was held last month at Suzuka Circuit.
It was sponsored by Land Mobility Inc, owner of Suzuka Circuit, and Panasonic was an official partner of the event.
Panasonic promoted its "KV-40 Challenge" where cars were powered on 40x AA rechargeable nickel-metal hydride (NiMH) batteries. In this challenge, teams were invited to independently produce single-seater electric vehicles, powered by EVOLTA batteries, and complete 3 laps around the 5.8 km Suzuka circuit which features a maximum elevation change of 50 meters.
75 teams from all over Japan participated, ranging from junior high school teams to serious hobbyists, with average speeds on the track reaching up to 60 km/h and it was noted that driving skill definitely played a large part in participant success.
The winner of the time trial was "Ahiru-Ecopa Racing Togo" team.
With just 17 days to go before 43 teams from 24 countries take to the start line in Darwin on October 6 to contest the Bridgestone World Solar Challenge 3,000 kilometre quest across Australia; one team is already putting its revolutionary 4 seater solar family car, Stella, through its paces in Darwin.
First time entrants in the inaugural Michelin Cruiser Class, Solar Team Eindhoven of Eindhoven University of Technology from the Netherlands are hoping their pre-race road testing in Darwin will pay dividends across the Aussie outback. Purpose built for this year’s event ‘Stella’ is the first ‘energy-positive car’ with room for four people, a trunk, intuitive steering and a range of 600 kilometers.
Competition in the Michelin Cruiser Class is not about finishing first across the line. It is about taking the technology to the mainstream and developing a car for the future Competitors will be judged on energy use and efficiency; how many people they’ve carried and over what distance and the potential of the design and practicality to appeal to the mainstream motoring market. ‘Stella’ will have her work cut out for her with competition from the German Bochum team, whose former car, the ‘BoCruiser’ inspired the category; Australian teams from Uni NSW and TAFE SA; and teams from Japan, Taiwan, USA, Canada and New Zealand.
Teams in the Elite Challenger Class are also well prepared. An unprecedented number of crews arrived in Australia early including America’s most successful solar team, University of Michigan who have yet to post a win here. They’ve been venturing out on test runs, and have even organised a ‘mock race’ to simulate the real Challenge in every way possible.
The Dutch Nuon Solar team from Delft University, believes their car, Nuna 7 can deliver their fifth World Solar Challenge from seven attempts. Until recent challenges they dominated, winning in 2001, 2003, 2005 & 2007. Their excellent record was thwarted in 2009 and again in 2011 by the impressively slick Japanese Tokai University team. Team Tokai are here to win and will not give up the title without a fight. Others to watch include Team Twente with their car, Red Engine, and Stanford University, who hope their car, Luminos, will live up to its name and be a leading light.
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 European automaker joins a growing field of alternative energy vehicles on the market. 
As automakers race to make cheaper electric cars with greater battery range, General Motors is working on one that can go 200 miles per charge at a cost of about $30,000, a top company executive said.
Vice President of Global Product Development Doug Parks wouldn't say when or if such a car will be built, however.
Currently GM sells the $35,000 Chevrolet Volt plug-in hybrid, which can go 38 miles on electricity before a gas-powered generator kicks in. It also offers the all-electric Chevy Spark subcompact that can go 82 miles on a charge. It starts at $26,685. Electric cars are eligible for a $7,500 federal tax credit.
The 200-mile car would cost about the same as the current Volt, and it would match the range and be far cheaper than Tesla Motors' $71,000, all-electric Model S. The Model S can go up to 265 miles on a single charge.
A moderately priced electric car with a 200-mile range would make electric cars more appealing to Americans, solving the two chief complaints about such cars: Anxiety over running out of power and high price, said Tom Libby, lead North American analyst for the Polk automotive research firm.
"That would be a huge step forward, no question," he said.
Currently, cars powered solely by batteries make up only 0.3 percent of U.S. sales, Libby said, but he's confident that would increase if an automaker came out with a moderately priced 200-mile car.
Tesla gets accolades for the Model S, including the highest test score ever recorded by Consumer Reports magazine. And the Palo Alto, Calif., company also is working on a mass-market electric car. CEO Elon Musk has said it will have around a 200-mile range and cost about $35,000. It could go on sales as early as the end of 2016, he has said.
GM has taken a different approach from Tesla, Parks said, pricing electric vehicles from around $25,000 to about $40,000. They don't go as far after each charge, which has kept battery costs down and made the cars more affordable, he said.
"Their pricing is up there for a real unique customer," Parks said of Tesla. "The real trick will be who can do a 200-mile car for more of the price range I'm talking about. We're all in races to do that."
The 200-mile car won't be the next-generation Volt. Speaking at a Monday event to show off GM's expanded battery laboratory at its technical center in Warren, a suburb north of Detroit, Parks said that GM engineers are now working on a new Volt, which will go a little father on electricity than the current model and cost a little less. He wouldn't say when it will arrive in showrooms or how much it will cost.
GM on Monday showed off a 50,000-square-foot addition to the battery lab. The added space, which nearly doubled the lab's size, will let the company test batteries and computer controls much faster than before. Parks said the goal is to develop electric cars twice as fast as the company could in the past. It took GM about four years to develop the Volt and bring it to market.
A famous quote from Soichiro Honda, the legendary founder of Honda Motor Company, says “Racing improves the breed”. There's no doubt many Formula One teams have used the phrase to imply a legitimate link between innovations made in racing that eventually benefit us all as the technology from top-level motorsport filters down into road cars, although it would be hard to convince anyone of a practical use for an off-throttle blown diffuser in a hatch back.
Likewise solar racing cars have made significant contributions that have lead to today's current crop of mass produced Plug-In electric cars. It all started with the winning vehicle of the very first World Solar Challenge in 1987. GM's Sunrayer was designed by Hughes Aerospace, (the company originally founded by Howard Hughes) at the time a division of General Motors, in collaboration with a smaller aerospace company called AeroVironment.
More than a dozen Caltech graduates participated in Sunrayer programs at AeroVironment, the most deeply involved was Alan Cocconi who was responsible for the power electronics systems. This included everything from motor controller through battery management to telemetry.
The Cocconi designed MOSFET based three phase AC motor drive inverter ran a 92% efficient 10 hp (peak) motor that drove the left rear wheel of Sunraycer via a cogged belt.
Sunraycer won Pole with a top speed of 109 km/h and lead the 24 car field from start to finish covering the 3,005 km route at an average speed of 66.9 km/h (41.6 mph), 50% faster than 2nd place.
Following the World Solar Challenge success, in early 1988 GM insiders proposed the idea of making a very efficient EV with the knowledge gained from Sunraycer but to make it an affordable car with decent range and performance equal to a petrol powered car. Work soon begins at AeroVironment on the 'Impact' based around a 15 kWh Lead Acid battery pack, Al Cocconi again responsible for power electronics design.
The Impact EV concept car was launched at the LA Auto Show in Jan 1990 and the car so well received that by April GM announced the car would go into production. The Alan Cocconi designed motor controller for the Impact, a direct descendant of that used in Sunraycer, were refined by Hughes Electronics and went into the GM EV1 when production started in 1996.
Based on his work to date, in 1992 Alan Cocconi founded AC Propusion to produce electric vehicle drive systems featuring high performance, high efficiency induction motors and integrated high power battery charging. The original test bed was a not too glamorous Honda Civic but once the powertrain design was debugged, a Piontek Sportech kit car chassis, originally designed for a Suzuki GSX-R motor, was converted into an EV sports car called t-zero.
Launched in 1997, the 1040 kg t-zero, powered by 28x lead acid batteries, started to make headlines with it's 0 to 100 km/h in 4 seconds levels of performance. By 2003 the car had been upgraded with 6,800x 16850 Li-ion cells with a single charge range of 480 km, a 320 kg reduction in kerb weight and 0-60 times reduced to a supercar beating 3.2 seconds.
If some of these specs sound similar to the Tesla Roadster, that's because the Roadster was developed by Tesla Motors to mass-produce AC propulsions t-zero, the first EV to demonstrate the performance and range potential of lithium ion batteries and the car that can legitimately be credited with inspiring today's mass produced plug-In electrics from GM, Nissan, Mitsubishi etc. In fact Tesla Motors was founded to commercialise Alan Cocconi's work and the Tesla Model S uses technology licensed from AC Propulsion.
Today's solar racers are still blazing a trail years ahead of the automotive industry, witness BMWs i3 Electric car, the first all carbon fibre production car. In the area of powertrains, every WSC winner since 1999 has used direct drive in-wheel motors (road car in-wheel motors are currently being developed) and surely in won't be much longer before the 12.5% of Australian homes that have roof-top PV systems installed realise they already have the infrastructure in place to solar power a plug-in electric vehicle for their daily commute?

At the Frankfurt motor show last week, there was a palpable sense that technology for autonomous driving was moving quickly from laboratories to dealers. At the Frankfurt motor show last week, there was a palpable sense that technology for autonomous driving was moving quickly from laboratories to dealers. 
FIA President Jean Todt and Alejandro Agag, CEO of Formula E Holdings, earlier this week (September, 10) revealed the much-anticipated new Spark-Renault SRT_01E fully-electric single-seater during the opening day of the prestigious 65th International Frankfurt Motor Show.
Watched by invited guests and members of the press, the SRT_01E has been designed and built by Spark Racing Technology, headed by the renowned Frédéric Vasseur, together with a consortium of the leading manufacturers in motorsport, and will compete in the inaugural FIA Formula E Championship - the world’s first global electric race series beginning in September 2014.
Using the very latest technology, the SRT_01E aims to push the boundaries of what is currently achievable in electric motorsport, whilst ensuring a balance between cost-effectiveness and sustainability, in addition to coping with the demands of racing entirely on city-centre circuits.
The car’s monocoque chassis has been constructed by leading Italian firm Dallara and has been aerodynamically designed to aid overtaking. Made from carbon fibre and aluminium, the chassis will fully comply with the 2014 FIA crash tests.
Providing the electric motor, gearbox and electronics is McLaren Electronics Systems, the world leader in high- performance technology for motorsport. Williams Advanced Engineering, part of the Williams group of companies that includes the world famous Williams F1 Team, is responsible for the design and supply of the batteries and their battery management systems; producing 200kw (the equivalent of 270bhp).
Overseeing all the systems integration, performance optimisation and powertrain electrical safety is Formula E’s Technical Partner Renault, a leader in electric vehicles and an expert in motorsport thanks to its Renault Sport Technologies and Renault Sport F1 programmes. Meanwhile, custom made 18-inch treaded tyres have been created by Official Tyre Partner Michelin, with just one durable tyre to cater for both wet and dry conditions and helping to reduce overall costs and promote sustainability.
“I congratulate all partners involved in the production of the fully-electric SRT_01E car – it is a fantastic achievement,” said FIA President Jean Todt. “The innovative technology deployed follows the best environmental practices, highlighting the potential of the Formula E Championship to spark a revolution in the development of new electromobility systems, not just for motorsport but also for everyday use. This new championship builds on the FIA’s traditional role as a leading promoter of innovation, technology and performance in the automotive sector.”
The car, which has been 10 months in the making, will be used by all 10 teams and 20 drivers competing in the new zero emission series although only for the first season as Formula E is an ‘open championship’ designed to encourage manufacturers to build their own car to help accelerate R&D around the electric vehicle. A total of 42 cars will be produced by Spark with each driver using two cars during the one hour races.
Alejandro Agag, CEO of Championship promoter Formula E Holdings, said: “With Formula E being an open championship, the series gives manufacturers the opportunity to showcase their electrical energy innovations and we’re delighted to have Spark Racing Technology as the first, and for them to produce our new fully-electric Formula E car. Spark has enlisted the very best companies in motorsport to aid with its development, with Dallara, Renault, McLaren, Williams and Michelin all leaders in their respective fields and it’s an honour to welcome them here today. The Frankfurt Motor Show is also the perfect environment to reveal our new car. Many leading manufacturers at the Show today are unveiling their new electric road cars but not just one offs, full car ranges, demonstrating how times have changed and why the time is right to launch the new FIA Formula E Championship.”
Frédéric Vasseur, President of Spark Racing Technology, added: “I am extremely proud and happy to work with the partners Spark has gathered together to form this unique consortium, a first in the history of motorsport. I regard each and every one of these partners with the highest esteem, I have worked with them throughout my career and they have accompanied me in a lot of the successes I have been fortunate to achieve in my other activities in traditional motorsport. All consortium members are driven by a motivation to make this innovative project a success.”
Patrice Ratti, CEO of Renault Sport Technologies, said: “As a global leader for the production of electric vehicles and with a unique expertise in motorsports ever since the company was founded, the choice of Renault as technical partner to develop the fully-electric SRT_01E car for the FIA Formula E championship was obvious. Renault engineers and motorsport experts are directly contributing to the overall powertrain architecture and are in charge of electric systems' specifications and integration, benefiting from the experience acquired while developing the new 2014 Renault-Energy-F1 Power Unit. Renault is also working with Spark to enhance the performance and safety level of the SRT_01E car powertrain. The objective is to design an outstanding race car that will be clean, reliable, safe as well as fast and responsive.”
Peter van Manen, Managing Director of McLaren Electronic Systems, said: “These cars are going to be brilliant racing through the centres of cities. Electric motors deliver instant torque and acceleration and that is what McLaren is all about. Performance and efficiency. Our electric motor, developed originally for the McLaren P1™, has the highest power-to-weight ratio in the world. McLaren is proud to provide the performance behind Formula E.”
Sir Frank Williams, Founder and Team Principal of Williams, commented; "Motorsport is moving towards a greener future and the FIA Formula E Championship will be a prime opportunity to showcase the latest green technology that has its origins in motor racing. Williams has a track record in developing hybrid technologies and we are proud to be supplying the battery and battery management system for the car that is being launched today. These components will be a pivotal part of what makes the car so green and the team at Williams Advanced Engineering is working hard to develop a battery system that is reliable and makes for excellent racing."
Andrea Pontremoli, CEO of Dallara Automobili, said: “With our single-seater cars running successfully in the most important categories and championships all over the world, we could not lose the opportunity to be part of the new Formula E exciting challenge and we are very thankful to our long term partner Frédéric Vasseur for the credit he gave us. We will use all our experience and know how to design and build the best possible chassis in terms of performance, reliability, ease of use and safety. The safety aspect is particularly important for us and we are working hard with Spark and the FIA to set new safety standards for such an innovative championship.”
Pascal Couasnon, Director of Michelin Motorsport, added: “Michelin is the official tyre supplier to the FIA Formula E Championship for the next three years [2013 to 2015]. This new discipline is of special interest to Michelin because it is a means to work on the design of efficient tyres to optimise the range of the formula’s single-seater cars. These solutions need to be extremely versatile in order to adapt to different weather conditions without losing any of their pedigree as genuine racing tyres. For Michelin, it is an additional opportunity to carry over the innovations developed for motorsport from the race track to the street.”
The SRT_01E will undergo a stringent FIA crash test followed by an extensive testing programme.
