Toyota CEO Says “Silent Majority” of Auto Industry Is Doubting EV-Only Future

You’re getting like 1.3-1.5 kWh with that charger. Assuming an 90% efficiency on charging (~1.2kwh). You wouldn’t be able to really do half of the average American daily commute (20 miles) and use your heating system to bring the car up from -5 C to 20 C.

Your car is likely going to be using 400-450 wh per mile until it’s warmed up and maybe down to 320 wh per mile for the rest of the trip. That’s ~10 kWh for your one day commute.

Now this is assuming basically a lot of perfect conditions for winter time driving. Also it’s assuming no traffic, because once you add waiting in traffic while heating up the interior of the car the power use skyrockets.

Also this is assuming you’re even able to hit 90% charging efficiency on 110V which honestly I’ve never seen personally.

I'm not really sure what to tell you. Empirically, I plug the car in when I get home, and that charges it well enough that I never worry about range except long distance trips. The car says I averaged around 30 kWh/100km on the trip that I took today on the highway, though it's also warmed up today all the way to -11C. Units are metric even though I'm in the U.S. because imperial units are silly.

It helps that I've got a 62 kWh Leaf, so I've got lots of range to start with.

How long is your commute though and are these low temps normal? I get about 3-4 “miles” of charge per hour with 110v and honestly that’s barely enough.

I WFH, so no commute. These temps are pretty normal for winter where I am.

I don't know what your situation is, but you'll honestly probably have good luck with just finding a regular outlet somewhere at work and trickle charging. I've done several vacations where I just asked where an outlet was, and left the car to charge up to 100% for the return trip. It's a lovely trick that gas cars can't duplicate.

I’m fortunately WFH as well but installing a 240V outlet wasn’t too bad.

This is one of the things non North Americans don’t have to worry about.
