I've been keeping track of charges since getting my leaf a few weeks ago and have done 5 fast charges out of 13 charges in total, using everything from L1 house to L3 listed below.
I've noticed that with each DCFC, the kWh/% is clearly trending down. Any ideas why?? I've considered the starting and ending %'s, the temperature, used different DCFC's, and have no clue why just this number is trending down.
This number clearly trending down appears to me that it implies the battery is losing capacity. ie. at first it took 0.207 kWh to raise 1%, but now it takes only 0.185 kWh to raise 1%. The kWh values are reported by the chargers, while the % is my dash display.
But that's also contrary to my Hx going from 99.5 to 106% and down to now 104% over this time.
edit.. crap. sorry for formatting below. it looks like an organized table in the text input and goes to crap in the published post. Out of exasperation and a desire to go to sleep i've added semicolons.
