On top of that, there is the cost of installing a circuit and EVSE, often costing over a thousand dollars and the lack of low cost charging at work..
SO, while I installed a 240 volt circuit, it is quite probable that it is not required
If you bought a brand new Niro, fully charged and it said, like mine, 292 miles on the GOM
Then you plugged it into your 120 volt outlet after driving home, it would be at 292 miles in the morning
Say you commute 20 miles to work, 40 miles , down to 252
Monday you come home and plug in, 120 volts gives you about 5 miles per hour
Tuesday, same thing, still says 292 miles, drive to work and back, 40 miles, store run , 50 miles total, charge for 12 hours, wed morning, still at 292
Wednesday, uhh, ohh, kid is sick, run to school pick them up , go back to work, work late to make up. You drove 85 miles and didn't plug in till 9 pm
Thursday morning, 9 hours later, GOM says 252, 40 miles commuting, GOM says 212 when you get home. charge 13 hours GOM at 277 in the AM
Friday, go out with the boys, add a dozen miles, home ad midnight, GOM says 225 when you plug in, but since you aren't getting up early, you charge till 10 am,
275 on GOM, Fart around run some errands, 25 miles, but ends up plugged in 14 hours of the day, so Sunday morning it is at 292 on the GOM, again.
Oh no, got to go see uncle morty today, 90 mile round trip on the highway, eats 110 miles off the GOM, down to 182 when you plug in Sunday night at 8pm.
11 hours later you leave for work, GOM says 237, down to 197 when you get home, 14 hours later it says 267,
by Wednesday, you are back to 292
The absolute living hell and stress of 120 volt charging
No one is charging their EV every day like that, they are probably plugging in every other
So, no you don't 'have' to spend thousands installing a 240 volt outlet, it is convenient and adds peace of mind
BUt as you can see, even with a 25 percent longer than average commute, you are not in any danger of being unable to travel an unforeseen 150 mile round trip.
Without having to charge anywhere but home
on 120 volts
