32 Series Automotive Class Lithium Ion™ Cells. (http://www.a123systems.com/newsite/index.php#/products/cells32series/)

http://www.cleanmpg.com/photos/data/501/A123Systems_-_32_Series_Cel.jpgA123System’s - May 15, 2007

These larger format 32 Series Cel’s have a life expectancy of 10 years!

A123Systems recognizes that the impending transportation revolution requires industry-specific solutions. To that end, we have developed two Automotive Class Lithium Ion cells, the ultra high power AHR32113M1Ultra and the more energy dense AHR32157M1HD.

These two cells, designed for HEV and PHEV applications offer extremely low cost per Watt and Watt-hour, respectively.

The AHR32113 uses the new Ultra electrode design, offering yet higher power over that seen in the traditional 26650M1.

Alternatively, the 32157 uses a more energy dense electrode, geared for the higher energy requirements of the PHEV marketplace, while not sacrificing the power capability needed for charge-sustaining operation.

Contact us if you are designing HEV or PHEV solutions to find out how our 32-series Automotive Class Lithium Ion cells can enable your application … http://www.a123systems.com/newsite/index.php#/products/cells32series/

Come on, hurry up with the PHEV kits. And make them affordable. And make it so my car can fly. And transform into a giant robot. :flag: :D ;)

I can't find any specs on these 32 series cells. Got any info (size, Ah capacity, cost)?

Actually, I'm personally more interested in these for EV use than for PHEV. EV is out of fashion right now, but would work very well for a commuter car in my family.

Hi WriConsult:

___Not sure as the Series 32 Cels were announced just last week. A123 did post the CAP loss over the number of cycles and it is huge: Cycle Life – All electric range (http://www.a123systems.com/newsite/index.php#/applications/phev/pchart2/). How about 2,500 cycles at 1C to 90% cap? I know more then a few EV’ers that would love that kind of capability ;)

___I have read that the std. M1’s are expensive as all get out ($7.00 per in quantity?) and those available through the developer kits are over $20 a piece w/ the following specs: A123Systems ANR 26650M1’s (http://www.a123systems.com/newsite/pdf/ANR26650M1_Datasheet_FEB2007-1.pdf) :(

___Good Luck

The graph is for 100%DOD, so at 90%DOD the cycle numbers would be even better.
The RC forums have really been abusing the original cells, 10C and they have been holding up very well. AFAIK the chemistry is LiFePO4 which allows some overcharge compared to Li ion. This makes charge balancing a lot easier.

Good Luck

Hi Hobbit:

___It sounds like somebody we know is looking for a job w/ A123 ;) I would pick up the phone and give them a call?

___When you do get the job, could you send me a HyMotion/A123Systems conversion kit w/ the new Series 32 HD Cels to test in a Prius II PHEV conversion please :D

___Good Luck

___Wayne

This makes charge balancing a lot easier.LiFePO4 seems vastly superior (to my mind) over the cobalt based Li-ion widely in use now, despite the somewhat lower energy density, since they don't blow up like TNT if you overcharge them, or overheat them, or overdischarge them, or have minor impurities in them, or breathe on them wrong.

EV is still some ways off in my future, but I am planning on upgrading my bike-light system for next winter. It's currently NiMH and I am definitely looking at LiFePO4. Things are progressing rapidly. THe fact that the RC people are getting good results is very promising indeed.
