So my Jeep is becoming almost non-functional.
It used to be I would get a low voltage alert occasionally on the = highway when going 60+ mpg (where I tended to sustain 300+ amps for more than a few seconds when = accelerating) Now I get low voltage alerts from my BMS and from the Soliton for very = moderate acceleration and at much lower speeds (like 35 mph). I had someone test a few of my batteries, and they test came back pretty = good. I haven't measured all of my batteries (I have mini-bms so it's hard to = know the exact state of things) but I feel that all of my batteries are basically sagging (vs having 1 = voltage drop in my system somewhere.) I'm not sure if I need a new battery pack or if there's something else = going on. My pack voltage drops from 160V to 120V during decent acceleration. This seems too much. It = seems unlikely that all of my batteries are bad though. What I would like to do is put my jeep on a full vehicle dyno and test = the voltage drop at various places to see if something else is awry. Not sure if this is possible, = but I'm not sure what other options I have (besides hooking up a few multimeters to = various spots, driving around, recording data, then moving the connections and trying again.) Any other ideas? thanks! -ben www.evalbum.com/4001 -------------- next part -------------- An HTML attachment was scrubbed...
