Hi,
I am new to EV and Leaf. Few questions about battery state.
Leaf 2017 (30kWh) used in Bay Area:
15K miles
SOH=88%
Hx=70%
below 20mV cell voltage difference (varies 4mV-20mV)
120 QCs 190 L1/L2
Questions:
1) It appears that the Hx is lower than what others see? I cannot find any definition nor correlation with SOC. Is the meaning explained somewhere (some handwriting about some measure of "ability to accept charge" and or "battery resistance")?
2) Is the SOC of 88% w/ on 15k/3yr low or a ok?
3) Seems that statistically it was charged every 3-4 days in 3yr, hence possibly to full?
4) Seems to loose range quicker at the top of the charge (on a 30mile mixed freeway/highway drive went from 95m to 50m range) than below 50% starts to slow down (return trip was 50->20 estimated so closer to driven miles).
5) Is driving at 65mph usually consuming much more energy than at 55? (Energy Efficiency shows ~3m/kWh at 65)? Normal?
Thanks,
Michal
