In between following sports and writing haikus, I've noticed that the Leaf can't catch a break. As if temperature management problems in Phoenix weren't enough, the NY Times' Wheels blog and Plugin Cars each report that for eleven Leaf owners, something has gone haywire between the Nissan Leaf and the GE Wattstation, leaving their batteries severely damaged.

TTAC's Alex Dykes offers a clear explanation of charging an EV or plugin hybrid in the US. Briefly, the EV's onboard system manages the charging as long as the charging station meets the minimum Society of Automobile Engineers (SAE) J1772 standard. What could go wrong? Dykes speculates:

Assuming there is no design fault inherent in the Wattstation’s “control pilot” design (and we might assume this logically because the issues are limited to Nissan Leaf vehicles only), the most likely possibility is a problem with an underrated or faulty D1 diode in the Leaf’s charger that makes the control pilot circuit more susceptible to transient current and failure. While it does seem fishy that the problems are only reported with the Wattstation and not the popular Leviton and Nissan branded chargers, the issue likely comes down to surge suppression and bad luck. It is likely that Nissan uses a D1 diode with a lower rating (and therefore affording less protection) than the Volt and Prius plug-in. With so few EVs on the road, and little public information on the specifications of electrical components in the chargers it is hard to say for sure.

Last week in Mississippi, strange bedfellows former DNC chair Terry McAuliffe, former RNC chair Haley Barbour and former President Bill Clinton grandly unveiled the MyCar — an EV made in America.

"Too many people have given up on American manufacturing, saying manufacturing jobs are not coming back. But GTA set out to prove them wrong," said Terry McAuliffe, chairman of GreenTech. "For too long, America has been inventing products here and sending the production jobs overseas. But we're part of a rebirth for American manufacturing. We're proud to bring manufacturing jobs back and prove that the U.S. is still the world leader in technological innovation and manufacturing."

After Beijing, Michael Phelps swore that he was done, finished with the grueling 400 meter Individual Medley. A day or so ago, Phelps dodged speculation about whether he would swim the 400IM again, even refusing to answer when he would shave his fu manchu mustache so as not to give away the time of his first event in the US Olympic Swimming Trials in Omaha.

The 400IM was the first event today. You start with 100m Butterfly, and it is nice to get that over with because swimming Fly when you're tired is no fun at all. Then you swim 100m Backstroke. Back lets you breathe a lot more, but isn't quite as restful as it seems in Esther Williams flicks because you have to kick like blazes. Then comes 100m Breaststroke, which to my mind is even more grueling than Fly, and your legs are already burning. And finally you can open up with 100m crawl, the fastest stroke, if your arms aren't already full of lead lactic acid. I have swum a 200IM, but I've never even attempted the 400.

Phelps, Chase Kalisz and Kevin Webster represented the North Baltimore Aquatics Club, where I swim, so it was fun to track them on the Omega Timing site. Webster looks to be about 23, and Kalisz is 18. I wondered if Kalisz was one of those kids zooming by in the afternoon practices, but apparently he swims in the mornings.
