As you may have noticed, the blog entries have dropped off rather abruptly in recent weeks. I've sent three e-mails and one phone call to Electro Automotive asking about the status of the battery racks/boxes and received no reply. As you might imagine, I'm a bit frustrated with this and don't really know what to do next. I should be getting the 18 8-volt golf-cart batteries from American Battery Company early next week.

Chairman Sawyer, Members, my name is Marc Geller, and I represent the San Francisco Electric Vehicle Association. Many of our members, including myself, drove ZEV Mandate battery electric cars - GM EV1, Honda EV+, Ford Th!nk City - until they were confiscated by the automakers. A few of us still drive Toyota RAV4 EVs - a truly great car. I hope Board Members understand that we continue to use these zero-emission, zero-petroleum cars in our daily lives.

F or those who think that GM is not serious about its new PHEV , the Volt , here is a piece that makes you think they are: The Volt To Be Lutz's Legacy May 21, 2007 So, I heard General Motors’ Bob Lutz on National Public Radio’s “Wait. Wait Don’t Tell Me” this past Saturday.The GM product boss said the vehicle he is most excited about, and the one he thinks will be the most significant for GM, is the Chevy Volt.

Synovate Motoresearch presented some very interesting survey results at the Advanced Automotive Battery Conference in Long Beach, CA last week, as reported in MIT's Technology Review. Simply put, as the first sentence of the article states, [W]hen consumers understand what plug-in hybrids are, they want them. All that's needed, the survey discovered, is a dollop of education.

Tony Blair came to DC to say farewell. And make one final pitch for American cooperation on climate change. At a Rose Garden press conference within earshot of anti-war protesters beyond the White House gate, Bush's prepared remarks included this: And we talked, of course, about climate change. We spent a lot of time on climate change. And I agree with the Prime Minister, as I have stated publicly, this is a serious issue, and the United States takes it seriously, just like we take energy securi

GM Vice Chairman Bob Lutz took his promotion for the serial plug-in hybrid Volt to an NPR game show, "Wait, Wait, Don't Tell Me." The NY Times reports : With the same enthusiasm that he has long used to describe high torque ratings and engine displacements, Mr. Lutz touted the Volt’s mileage, which he estimated will reach 151 miles per gallon, fueled by a combination of electricity and gasoline.

I went back to Parkrose hardware today to pick up stainless steel bolts to attach the motor cables to the controller. In the process, I got some two-conductor wire to make the connections to the potbox switch and backup-light switch cleaner. Here's the somewhat finished potbox. Note the added accelerator cable and extra pullback spring on the potbox arm.

From Saturday's New York Times story " Cheney, on Carrier, Sends Warning to Iran " Vice President Dick Cheney used the deck of an American aircraft carrier just 150 miles off Iran’s coast as the backdrop yesterday to warn that the United States was prepared to use its naval power to keep Tehran from disrupting oil routes. Oil seemed to be on Mr. Cheney’s mind yesterday when he told 3,500 to 4,000 members of the Stennis’s crew that Iran would not be permitted to choke off oil shipments.

Last night was the monthly OEVA meeting. There were many electric vehicles there to ponder and I got a chance to chat with a bunch of people. I'm kicking myself a bit for not bringing my digital camera, but that's life. Victor Tikhonov of Metric Mind and I talked about his new EVision system and how I might get involved with the embedded programming for his latest BMS (battery management system).

I received a package from Azure Dynamics yesterday with a field upgrade to the bolts on the AC24 motor for the EV kit. Apparently, the nylon washers weren't good enough to hold the bolts in under all conditions and some of them may get loose. I'm happy that Azure sent these before I started driving the vehicle around, although no major field failures have been reported.

The British Government is attempting to strangle the electric car baby in its London cradle. The Times Online reports the British government's Department for Transport (DfT) has conducted a safety test on the all-electric Reva G-Whiz and found it wanting. The small, 45mph zero-emission vehicles have found a ready market in London - 850 sold so far - where electrics are exempt from the stiff daily congestion charge for driving in central London.

My 914ev partner-in-crime Randy (who purchased the very first 914 AC kit from ElectroAuto) e-mailed me some photographs of how he's wiring up his terminal blocks and relays. Here are some pictures and descriptions from his 914 AC conversion. (Thanks, Randy!) Excerpt from Randy's e-mail: I've also started on the wiring kit. I looked at the instructions and decided to rearrange things (typical).

I'm still waiting on the battery racks/boxes from ElectroAuto, so I took care of a bunch of little things that have been neglected so far. Here's the battery tray that the directions said to remove. It came out surprisingly easily with a hammer and mini-crowbar since there were only a few spot welds holding it in. One of the other 914 kit converters questioned why the accessory battery couldn't stay in the original tray, but I decided to remove it anyway and have the accessory battery up in the

I spent all day today going through those hundred technical articles on SOC (state-of-charge) and SOH (state-of-health) algorithms for lead-acid batteries. They were all fascinating, but the one I really liked involved a Kalman filtering algorithm to constantly estimate the internal parameters of the lead-acid battery. The algorithm models the battery and samples the current draw and voltage across the pack.

Google.org is stepping up to the plate for electricity in cars. Calcars.org has received a $200,000 grant to continue its advocacy of plug-in hybrid vehicles. Founder Felix Kramer has been dogged and successful in pushing plug-ins into the national and international media. Everyday Prius owners ask me where to get their car converted to a plug-in. It is largely thanks to Felix that hybrid owners now desire something more than a gasoline-dependent car.

Since I'm still waiting on parts from ElectroAuto, I decided to take the plunge and do some extensive research on Lead-Acid battery technology. The 914 AC kit uses 8V golf cart batteries and I'm wondering if different batteries like Hawkers or Optima Yellow-Top batteries would be better. After researching different battery types, it looks like the Hawkers and Optimas can put out more amps for more torque and are more rugged, but the golf-cart batteries still rule in terms of capacity per weight

The California Air Resources Board , one of the culprits identified in Who Killed the Electric Car? , was originally charged with reducing pollution. Now it's actions are meant to help reduce carbon emissions and petroleum usage, as well. The electric cars produced to meet the Zero Emission Vehicle mandate uniquely contribute on all three counts. Of the transportation fuel options before us, only electricity can provide both near term mitigation of the many problems wrought by petroleum and the
