Hmm. Not sure that sounds right. That would mean my battery has lost nearly 11% of it's total capacity which would definitely not seem normal. When I look up data in Carscanner, it clearly shows a difference between SOC and displayed SOC, so the buffer still exists.
Could be BMS drifting is an issue. Basically without going down to near zero, or 100% the BMS can lose track of actual. The SOH you are seeing is what the BMS thinks, and that may not be entirely accurate. Many people charge to 100% occasionally for this reason. I have read that the remedy is to run it to near zero, then in one continuous charge to 100% (meaning it shuts off on its own). This also has the effect of leveling all cells, meaning evenly charged which can throw off SOH calculations as well. Lastly, it's not just battery usage, it's also age of the battery pack, and environment, especially very high temps. But of course you may have a weak cell or two.
That's a great idea. I have only taken it to about 20% once and I took it to 100% about 4 months ago on a short trip, and then immediately began the drive. I do live in Las Vegas, and it started hitting 105F a day here, so that may have had an effect too.
My dates are estimates of when I thought I saw those numbers. I did get some recall software changes done on May 5th, so the timing is in the ballpark.
Just hit 30k.
NIce ........ I corrected the thread title TYPO...... carry on.
