LockMart & EEStor (ultracapacitor tech) sign deal

[neilsox]

Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>My guess is Lockmart will loan EEstore the money to complete the testing and start production. If the product has few applications, Lockmart loses, only if EEstore files bankruptsy. Lithium-ion is also about 10 times the watt-hours per kilogram, but lithium ion will likely remain expensive because the risk of explosion must be miminized. Charging a 160 kilowatt-hour energy pack of either kind in 10 minutes requires a megawatt from the electric utility, which typically is available only in industral neighborhoods, and power distribution centers, which recently lost a high demand customer. The Tesla battery pack is 56 kilowatt-hours. Neil <br />Posted by nexium</DIV><br />1/6 th of a megawatt, however is likely available within a few hundred meters of most urban locations, on a&nbsp;usually available basis. That will charge a Tesla fully in 20 minutes or a 160 kilowatt hour energy pack fully in one hour, longer if the car&nbsp;charging facility has more than one simultanious customer. Of course, customers will often be half charged or more and just want a top off as they are about to leave on a long trip. With rare exceptions, it will be almost as convenient as filling a car gas tank. 160 kilowatt hours will likely power a large SUV for more than 300 miles. The customer may have put 50 kilowatt hours in his battery pack over night at his home where&nbsp;5 kilowatts for ten hours&nbsp;is typically&nbsp;available with&nbsp;two 240 volt extenion cords, without upgrading your electric service.&nbsp; Neil

Inc. said it is targeting the launch of its &lsquo;cityZENN&rsquo; EV, powered by EEStor ceramic ultracapacitors, for the third quarter of 2009. The cityZENN is planned to be a fully certified, highway-capable car with a top speed of 80 mph and a range of 250 miles &ndash; and because it plans to use U.S.-developed EEStor ceramic ultracapitors rather than lithium-ion batteries, the vehicle is planned to take less than five minutes to recharge.</p><p>The EEStor Electricity Storage Unit is projected to offer up to 10 times the energy density of lead-acid batteries at the same cost, and one and a half to two and a half that of lithium-ion batteries at 12-25% of their cost. EEStor, which has revealed little to date of its technology, has committed to launching it this year, and its first products are destined for ZENN Motor Co., which has invested in EEStor equity, and has an exclusive technology development agreement with the U.S. developer in respect of vehicles up to 1.4 tonnes GVW, and retrofit drivetrains.</p><p>ZENN Motor Company also plans to expand its product lineup for the 2009 model year with a four-passenger car and a utility &lsquo;LSV&rsquo; (Low-Speed Vehicle), and to offer other vehicle manufacturers a proprietory &lsquo;ZENNergy&rsquo; drivetrain, powered by EEStor, for various vehicle platforms, and to develop retrofit ZENNergy drive systems for the conversion of existing vehicles to electric drive.</p> <div class="Discussion_UserSignature"> </div>

<p>I would love for this to be true, but I am extremely skeptical. It just does not add up that something this revolutionary could go from unknown, unseen, unmarketed to production status in 18 months. </p><p>The Zenn website says that the current battery powered vehicle can go 245 miles on electricity equivalent to one gallon of gasoline. If the new vehicle is comparable, then they claim to be able to move that much electricity in 5 minutes. A gallon of gas has 120,000 Btu. There are 3413 Btu per kWh. Thus they move 35 kWh in 5 minutes. The rate is 420kW. If the outlet is 220V, then there are 2000 Amps flowing. That is one huge level of power and a huge amperage.&nbsp;</p> <div class="Discussion_UserSignature"> <p> </p><p> </p> </div>
