Using two diffrent canbus logs (one as I drove the car from GOM=6 to dead
(discharge) and the other logged during a charge to 100%(charge)) I was able to plot battery voltage versus gids across the full range (keep in mind my 100% charge stops at 244 NOT 281 like most of you). I was able to empirically establish that the ESR of the battery (and any wire between the sense point and the battery) to be about 70mOhm since any value higher or lower resulting in larger variation in the formula (battery_volts-battery_amps*esr) during my discharge log. I also labled the points where I recieved LBW, VLBW, turtle
, and dead
. As you can see once you get VLBW, you are past the knee and really need to stop driving or you can degrade your weakest cells by over discharging.
