I forgot about ChargeHub. Will it work on Apple CarPlay? I know A Better Route Planner will.
The big drawback I see to any of these systems, over the built-in mapping/routing software, is they do not know the current State-of-Charge of the vehicle, and cannot automatically initiate fast charge prepping.
(Not true of all EV's. Friend's Mach-E for example, Apple Maps can do all that. It knows your current charge level to more accurately route plan, can initiate battery prep, etc.)
