If I recall correctly, they did indeed use STM5-100MRE liquid cooled modules in the early Think models. Even earlier Pivco Citibee prototypes used SMT5- 100MR (air cooled). > That type of "cell"-blocks are still running here! For example in the > most of our old Renault Clio electric cars.

I don't think it affected the larger, golf-car battery size 180MR modules, which I'm pretty sure were of an earlier design. I don't know about the 140MR modules. These weren't as widely used, but were of similar design to, the 100MRs. More information on this problem here : http://www.evdl.org/docs/saft-failures.pdf Failure rate can usually be minimized by limiting the drive current to ~200 amps (2C). Thus the battery's power ability is low; a 180v battery would deliver only 36kW. If memory serves, Axel Krause of Brusa used early STM5-100MRE modules in a Mini-Evergreen for around a decade, with a 250 amp max Brusa inverter. He drove this EV for a 220km (!) Alps transit in 1997. http://www.brusa.biz/index.php?id=43&L=1 David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
