I went away for 10 days and was curious to see what would happen to the charge level on my Clarity while I was away. I fully charged it before I left and it was unplugged in the driveway while I was gone. Before I left, HondaLink showed 100% charged and 83km EV range. I checked HondaLink a few times while I was away and it always showed 100% until this morning when it changed to 99% (still 83km EV range). I returned home tonight, plugged in my car and it charged for 4 minutes for a whopping .17 kWh added at a total cost of $0.02 hydro.
