The info that I shared here was what I gleaned from talking with one of Nissan's engineers a little over 2 years ago. I have not taken the time to do any real time testing, more of the seat of my pants kind of experiences. Very difficult to quantify range vs charge level vs temperatures in our real world driving. If it seems that I am not getting the range that I want whether temperature or SOC related, I will generally modify my driving habits to compensate.
