EEStor & Zenn make announcements
June 4, 2009 by Rob.
This was posted from the AustinEV group and is significant since stealthy EEStor could be a major playah if their stuff actually works.
Dear ZENN Enthusiast, May 21, 2009 was a significant day for ZENN Motor Company as it confirmed the results of EEStor’s previously announced permittivity results. As many of you may be aware, the successful achievement of these results by EEStor triggers a couple of key events for the Company. Firstly, we will pay EEStor the milestone payment of US $700,000 per our Technology Agreement with them and, To read the news release, click here. Secondly, we intend to increase our equity investment in EEStor to the fullest extent possible. Further details regarding this investment will be announced when determined. The achievement of this key milestone is very encouraging towards the end goal of commercializing EEStor’s technology. For this reason, I am as optimistic as ever and remain committed to the mass electrification of the transportation industry. EEStor has also stated that their objective is to complete component testing by September 2009 and deliver production quality components and/or EESUs by the end of 2009. Please see the article from ‘All Cars Electric.’ All the Best, Founder and Chief Executive Officer ZENN Motor Company ZENN In the News: EEStor VP Says EESUs to be Delivered by End of 2009.(All Cars Electric, June 1, 2009) ZENN to increase EEStor ownership.(Toronto Star, May 22, 2009) ZENN CEO reveals details of EEStor’s progress.(Cleantech, May 22, 2009) ZENN Motor confirms EEStor battery results.

Electrons, wherefore art thou?
January 3, 2009 by Rob.
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.

Stealth mode Austin Li Battery company gets BIG VC $$$
August 9, 2008 by Rob.
I just saw an announcement that Austin based ActaCell (don’t bother w/ the site, it’s a 1 pager) raised $5.8M of VC money from DFJ Mercury Includes Google.org, Applied Ventures and Good Energie. They plan to hire key technical talent and to further develop ActaCell’s innovative lithium-ion battery technology for commercial purposes.

Battery Post Corrosion - what to do?
July 29, 2008 by Rob.
I was watering the RAVolt’s batteries this weekend (as usual, 1 basterfull per cell) when I noticed that one of the battery terminals is corroded. The powered is bluish and there is no acid splash around the terminal. I’m not sure what to do yet, just reporting the problem. I’ll ask AustinEV for help.

RAVolt maintenance & 16 mile drive
January 6, 2008 by Rob.
I finally got around to watering the RAVolts dry batteries. I gave them a nice long drink of electrons to see if I can get my range back into the 20s. They demonstrated their appreciation by making the RAVolt smell strongly of boiled eggs. Did I mention that I HATE boiled eggs? Do I think you care? Don’t answer, I know it’s a double “no.”
Anyway, I took the family out for egg flavored yogurt and a joy ride tonight. We were able to cruise 16 miles with two long climbs on 360 at highway speeds. The batteries were holding up nicely and I’m feeling optimistic that I did not completely crush them when I got stranded.
I’m planning to equalize the string (trickle charge 1 at a time) tomorrow after charging tonight.

Not my uncle’s Li batteries
December 20, 2007 by Rob.
But my uncle did send me an interesting link to new Lithium battery technology from Stanford. Even if this is not ready for market, the electron microscope picture of silicon nanowire’s absorbing lithium is amazing! The article has a concise description of Li battery chemistry.
