Like Viking79, I'm also seeing about 35 miles of EV range on the console at 100% charge -- outdoor temp is about 40F. (2018 Honda Clarity PHEV Touring) I don't see where Honda has included a means of gauging HV battery health. (Hopefully this is not a strategic omission.) I seem to recall Leaf owners in a forum discussing an aftermarket system from FleetCarma that plugs into a vehicle’s OBD-II port. I believe the idea was to collect & share performance data within the owner community. Question: has anyone identified options that Clarity-PHEV owners can use to monitor battery health/degradation over the lifetime of their vehicles? (Outside of Honda's computed range, and the actual EV miles driven per charge.) Obviously, this may present more of a concern for owners than lease holders.
