I own a 2019 Plug in touring clarity bought in 11/2019. Over the past 4 months there has been a steady increase in EV C harge from 44 mi to now 63 mi. I have two charger cords, one is the original 120 v and an aftermarket 120/240 v cord with adapter cords for 4 plug styes but have only fast charged once. Any other similar experiences and what is the technical explanation? Car running on EV almost exclusively without issues.
