Let's go metric with 2000 km. The 2021 Kona EV has a range of about 500 km. The level 2 charger at my house takes 9 hours to recharge from empty (i.e., overnight). That's 1.5 days to fully charge a battery offering a 2000 km range, in theory, which is half your estimate. A DC fast charger can recharge 400 km in 50 minutes (80% capacity), equivalent to 4 hours for 2000 km. Meaning those batteries will probably take closer to 5 hours to fully recharge when using the fastest chargers available today.
