Yes, this happens to me too. The ironic thing is that I can usually spot the recallibration before it happens because it will light up two green bars of charge and stay there, even though I can feel that the car is not doing any regen (zero resistance slowing me down). It will stay with the two bars, even if I apply the brake or give more/less gas, and then the SoC will drop like a lead balloon.

I don't have any doubt that this is a designed process that happens when certain conditions are met. What I want to understand is why these conditions seem to happen so frequently when I minimize battery use, don't use A/C, and don't live in an environment with extreme heat. Also, since it happens so frequently and since it does seem to drop the battery to zero, what is the long term harm in this happening weekly.

Are there a lot of hills in your normal driving? Do you use the glide frequently? Those are two things that pretty much define my commute--lots of hills and I glide (no Asst) about 90% of the time on downhills.
