After some minor painting, the battery replacement for the RAVolt went off with any issues.  The alternate cells Trojan T1275 were a good fit without needed to change the terminal connector layouts.

I especially like the new lifting ears.  We made some simple lifting straps so moving the cells was much easier than using the J150’s built in handles.  I wish they were in the original design because I could have aligned the cells to make it easier to have tie downs.

I have not yet tested the range on the new cells - I expect to be back to my 30 mile range.  Trust, but verify.

Now that the brakes are fixed!!  I took Alex for his first RAVolt drive.  With the old batteries, it takes a very careful foot.  He’s excited to have the RAVolt has his daily, so we’re getting new batteries.The current range is just about 2-4 miles (of very timid driving).It’s been 4 years since we got the first set (about this same date in 2007) and prices are up about 50%.  Each cell will cost $150 for the T1275.  If I tried to order the old J150 cells, they would be a special item and $200.The T1275 is the same weight and amp-hours.  It’s slightly shorter (13″ vs 13.75″).  That difference may come from the lack of useless lifting edges on the sides.   My big concern is the terminal posts, but those _appear_ to be the same.We’ll find out on Tuesday - that’s when the J150s go to the big smelter in the sky.  It will take a few days before I find the time for the install.BTW: My supplier is Continental Battery in Belton.   Thanks to Bill Gooch on the AustinEV list for the recommendation.

This was posted from the AustinEV group and is significant since stealthy EEStor could be a major playah if their stuff actually works.

Should be a big deal…politicians, Li EVs, and (potentially) Austin’s first Tesla.  See AustinEV.org for details.

My last two EV outings (16 miles & 12 miles) have been marked by atypical voltage sag.  It seems like the 18 month old batteries are not holding as much charge as they used to or the “cold” could be impacting them more than I expect.  Unfortunately, the I think the lack of daily commute based deep charge/discharge is limiting their recovery.

On a related note: having a high MPG car makes me less likely to drive the EV on longer trips.  Hmmm.

One of the most interesting technology items I’ve seen recently in the flood of EV announcements is Michelin’s Active Wheel.  Apparently they’ve been working on this a while and still have years to go.  However, it looks like a viable wheel (not-hub) motor approach.  Their use of active suspension may address the unsprung weight issues of hub motors.

Clair from AustinEV posted a link to the interesting gas2.org site.  They’re a automotive alt fuels multi-author blog.   I found their post about UPS’ hydraulic hybrid delivery truck interesting.  It’s important to keep in mind that Toyota is the only workable hybrid and there are some great alternative designs emerging (e.g. Chevy Volt).

If boxey and brown is not your thing, then consider Peugeot’s very hot looking concept diesel hybrid. A friend was asking me about this at a camp out last weekend and I had not heard about this offering. Looks like fuel efficient is starting to get sexy.

We had a busy weekend out at the Austin Maker Faire!  As usual, it was a great event.  Better coordinated than last year and bigger too.  I liked the addition of the Robot Wars.

Alex had a great time showing people how to hack their Wii Motes and even got a blue ribbon!  We had some interesting generational challenges because saying “mod wii mote” sounds like “may we mate” to a segments of the population.  Technology brings so much new vocabulary that it’s easy to forget not everyone immediately parses “google blogs from blackberries.”

Since I was busy with Alex, the RAVolt was left with her EV friends in the other part of the barn.  It was nice to drop in and see so many of the AustinEV/SanAntonioEV crowd (Aaron, Chris, Brian, Gary, and Alphonso).  Since Aaron brought the charger we were able to drive electric both days to the Faire!

With the nice weather, I’ve been driving electric nearly everyday and racking up the miles.  Today the RAVolt’s Odo spun to 150500.  The amount of gas I have not bought is adding up - hahahaha!

Even with the stock market meltdown, Laura’s impatient to get our Honda Fit….tick, tick, tick.

BTW: We’re planning to be at the 2008 Austin Maker Faire October 18-19.  The RAVolt will be in the AustinEV area while my boys have a table hacking Wii Motes - bring your mote and they’ll make the “A” button glow.  Alex is buying all the supplies out of his own $$$ with the dream of making a profit at the Faire (DIY kits for @ $10-12).  Can’t argue with that!

It must be Detroit in another galaxy because I’m having trouble believing the news that Chrysler is promising multiple EVs by 2010.  They’ve got a retro-modern EV blister thing, a totally hot Tesla-stomping electric Viper, a EV Mini-van, and an electric Jeep SUV.  Apparently some are pure EV and others are plug-ins.  Hmmm….this is getting interesting.
