I'm trying to figure out what the constant and 30-second Amp ratings are for some Leaf Busbars. The ones I have measure 0.78" wide by 0.08" thick. That calculates out to 40.25 mm2 (yeah, changing units) 1 awg wire is 42 mm2. BUT the busbar isn't insulated, and has a much larger surface area, so won't heat up as much. 1 awg wire is rated at 0.13 ohms/1000 ft.
It's about 1.25" between modules in a Leaf pack. That comes out to 0.00001354 ohms. at 200A, there should be a voltage drop of 0.0027V, or 0.542 watts. What I'm trying to figure out is if I need to stack several of them for the 5p17s pack we are probably going to do for a friends truck. -- Bobcats and Cougars, oh my! http://john.casadelgato.com/Pets _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
