I thought folks would like to hear the results of some of my testing. 1/2 inch smashed copper pipe, 200 Amps for a 2S2P pack of 8 Ahr "P" (for Power") Headway cells: Things stayed cool.
1/2 inch by 0.02 inch braided strap with smashed copper pipe at connections: 5 F rise in 90 seconds at 200 A 1/2 inch by 0.01 inch Al: 200A, 80F to 200F in about 15 seconds! This was done in the oxidized state. 1/2 inch by 0.01 inch Al: 200A, 80F to 200F in about 15 seconds! This was done with sanding and immediate Noalox. 1.75 inch by 0.02 inch Al: 200A, 80F to 160F in about 30 seconds. The Al performed way worse than theory predicted, then I think I figured it out. Al roof flashing from Home Depot is apparently not a very conductive alloy of Al. I'd guess better Al would perform much closer to Cu. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
