and welcome to the Forum.
For the Canadian SX Touring trim level on the EV model is the only one that has the "heat pump
" and the "Battery heating system"
The EX trim does not. The "Heat Pump" is like a house "heat pump" and is not efficient below the -10c (canadian celcius) mark. radiators are the after -10 heating. For the Battery heating system, you will be able to heat the cabin with the UVO app on your cell phone. kind of a cool gadget!
Personnaly, i would go for the EV SX trim level because the EV EX trim level has been "stripped" out of alot of big options too get the matching price of 45k for the federal 5000$ rebate. No heating seats and steering wheel, normal cruise instead of the adaptative cruise, no tech package, and much more.
For the Charging, 59h with a level 1 (120v) charger that comes with the car. A 9h on a Level 2 charger (240v) and on a Level 3 BRCC fast charger, 1.15h on a 50kwh charger for a 80% charge.
it's a really nice car too drive, i was able too have it for a week-end in June! did over 1700km on it in 3 days all electric with a 465km per charge (385km is the brochure mark).
** The Kona is too small for a 4 passenger ride, you will have alot of space and comfort in the Niro!
