How long should it take to charge an electric vehicle? At the Washington Auto Show. today, Think announced a partnership with AeroVironment to promote a fast-charging infrastructure (based on Level 3, or 440V, charging) which can power a Think City's battery pack from zero to 80 percent full in just 15 minutes. To emphasize the short time it would take to charge a Think using this method, Think CEO Richard Canny set a timer for 15 minutes during the press conference and called it a "major leap forward for electric vehicles." Think has been testing the Level 3 system (developed, in part, by Tokyo Electric Power Company, TEPCO) recently with its development vehicles and says that, "This work has confirmed the suitability of the fast-charge technology and readiness for commercialization."

Also, while we knew that EnerDel would supply the batteries for the City (full details here), Think announced today that only EnerDel packs would be used in the EV in the U.S. through 2012. Over in Europe, EnerDel will provide packs for at least 60 percent of the City EVs there. More details after the jump.

PRESS RELEASE

Zero to 80 Percent in 15 minutes: New Benchmark for EV Fast-charging
THINK, AeroVironment to Pursue Projects to Promote Fast-charging Infrastructure
EnerDel to be Exclusive Battery Supplier for THINK City in the U.S.

WASHINGTON, D.C., Jan. 26, 2010 – Electric vehicle manufacturer THINK today announced that it will work with AeroVironment, Inc. (NASDAQ: AVAV) (AV), a leading developer and supplier of electric vehicle charging infrastructure, to pursue demonstration and commercial projects using AV's level III fast-charge system and the THINK City electric vehicle. The projects will be designed to jump-start the development of fast-charge infrastructure in the United States.

The announcement came at a 15-minute news conference at the Washington Auto Show. Fifteen-minutes is the time it will take to charge a THINK City from completely depleted to 80 percent charged using an advanced fast-charge system, establishing a new benchmark for the rapidly developing electric vehicle industry.

"THINK and AeroVironment are setting a new standard for extremely quick re-charging – zero to 80 percent in just 15 minutes," said THINK CEO Richard Canny. "This is a major leap forward for electric vehicles. The development and deployment of very-fast-charge stations will help speed the electrification of automobiles in the United States and globally."

"For electric vehicles to achieve broad adoption as a practical alternative to gasoline-powered cars, safe, reliable and accessible charging infrastructure is necessary," said Michael Bissonette, AV senior vice president and general manager of its Efficient Energy Systems business segment. "Our portfolio of true fast-charge systems, commercial opportunity charge stations, and overnight home charge stations will help drivers integrate electric vehicles, such as the THINK City, into their lives and realize the benefits of zero emission transportation."

THINK also announced that it has chosen EnerDel, the Indiana-based lithium ion battery manufacturer, to be the exclusive battery supplier for THINK City electric vehicles sold in the U.S. through 2012. EnerDel also will supply at least 60 percent of the batteries for THINK City electric vehicles sold in Europe.
"EnerDel has developed an extremely energy-dense lithium ion battery for the THINK City," said EnerDel President Rick Stanley. "This battery has been designed from the earliest stages of cell development to accommodate the surge of current required for a new standard of rapid charging."

The AV level III fast-charge system employs a protocol developed by Tokyo Electric Power Company (TEPCO). THINK and EnerDel have for several months been using TEPCO fast charging daily to quickly recharge development vehicles. This work has confirmed the suitability of the fast-charge technology and readiness for commercialization.

THINK City, to be sold in the United States beginning this year, will have a top speed of more than 70 miles per hour and a range of more than 100 miles per full charge. THINK City has an onboard AC charger that can be coupled with an economically priced 220-volt THINK home charging station to provide overnight charging for the vehicle. It can also be charged using 110-volt current on a regular household outlet. The fast-charge system will be a supplementary alternative for customers' added sense of security and for fleets with daily mileage requirements exceeding the car's range.

"Our experience with more than 1,500 vehicles in use in Europe is that customers using the vehicle for daily commutes and trips around town quickly become comfortable with THINK City's range of more than 100 miles," Canny said. "For them, the standard over-night charging is a very practical solution. Fast charging's importance will be for high-use fleets."

THINK recently announced plans for a North American manufacturing facility in Elkhart, Indiana, where the company will build the THINK City beginning early in 2011. The new facility will be in addition to THINK's current manufacturing capability in Finland, where it has contracted with Valmet to build the THINK City.

THINK expects commercial fleet customers in the U.S. to be among the first users of the fast-charge system, but also anticipates that commercial enterprises – including shopping malls, convenience stores and parking garages – will quickly see the value in offering fast-charging services for their customers as a way to grow business and to demonstrate environmental responsibility.

      Does that mean 80 miles on a 15 minute charge?

      How rough is that on the battery?
        • 5 Years Ago
        Yes, since it has a 100 mile range. I did a quick google to try and find the battery pack size. I figured it was faster than the leaf because it's pack is a little smaller.
        Leaf claims 26 mins to 80%. Think with Endrel claims 15 mins to 80%. They have a few batteries choices when it comes to batteries. There sodium batteries operate a 260 - 360 degrees, very hot.

      Remember last year when everybody thought THINK was going away for good? Wow. Now they're leading the way with the fastest charging. Way to go!
      • 5 Years Ago
      15 minutes is just perfect for a nice little coffee break. Good job!
      Maybe we have one day batteries able to stand/handle that fast charge as standard procedure. Cause I don't see the space to build enough overnight charging ports in dense cities, not to mention safety and vandalism aspects.
      • 5 Years Ago
      Seems like the TEPCO level III charger will become the standard for the US, just like the Yazaki (J1772) for level II. It would be nice if they could have combined it into one plug.

      Good to see they're working with Aerovironment, a reputable company on the fast charging. I hope they're a success.

      Anybody know how many kWhr this batt pack is? If it's 25 kWhr then for a 15 minute charge that's about 200 amps through the wire!

      Fast chargers are more important to the success of electric car than Better Place's battery swapping scheme. Think alone is not enough - they need to work with bigger manufacturers such as Nissan and GM.
        • 5 Years Ago
        With a top speed of 70 it beats out the Wego Whip by 5 mph. It also has fast charge capabilities, not sure the Whip does. Think, Whip both have the same range.

      I propose a lightning charger which utilizes super-capacitors to charge the car within 5 tau. - more-or-less completely.

      I shall also market this technology under the name - "Arc of the Covenant".

      ;-)


        • 5 Years Ago
        what's a tau?
        • 5 Years Ago
        @Dan

        Well, in this context it represents the time constant of an RC circuit.
        However, the odd thing about such a time constant is that it changes with the circuit.
        http://en.wikipedia.org/wiki/Time_constant
        Capacitors charge extremely quickly, so I have always fantasized about using a super capacitor as a quick way of transporting charge to a mobile device (such as a car).
        But it truth it is not very practical I think for the given amount of charge you are trying to transfer in such a case today.

        ;-)

      Now build the Think Open please. I want one.
      • 5 Years Ago
      Yes, with fast charging the electric vehicle will become mainstream. I do have concerns on how fast charging affects the battery life. I would assume the car companies are taking this into consideration. Fifteen minutes is a magic number for fast charging. Most people would not mind charging for 15 minutes, getting a cup of coffee and stretching their legs before getting back on the road. I am ready to buy.....when will they become available in the U.S. I am looking at the Ford Focus Electric vehicle, but would take a second look at the Think if it came with fast charging and the charging system was available nationwide. Hopefully, fast charging will become the industry standard, sooner than later, for quick adoption of electric vehicles.
