Yeah well 19 hours ain't much better anyway, the point remains. I was going off the charge estimates on my dashboard FYI.

Sigh. No, it takes about 19 hours to reach 100% from 10%, with another 30 minutes or so for EQ to occur. L-1 doesn't work for people with long commutes, but let's try to keep the facts straight. (This from the guy who told the OP not to buy a 24kwh Leaf.)

A suggestion: ask work to install several 240 volt dryer-type outlets, and require employees who want to charge to provide their own EVSE and pay, say, $20 a month to pay for the wiring and power. That alone would thin the potential herd of charging employees, but it would also allow 2 employees per shift to recharge per outlet. You could then use the EVSE Upgrade service to make your charging cable 240 volts at 16 amps.


What is EQ? Waiting for the cells to balance?

I'm considering asking if they would be more willing to let me charge there if I supply and install the EVSE, pipe, wire and disconnect equipment. The openevse stuff looks like it's decent quality and I don't mind assembly at all.

Well I did 92 miles from 100% charge until turtle today, the disclaimer being that I had to stop at an L2 charger for 30 mins on the way home and took on an extra 3kwh. I was doing awesome on the way to work, 5.2 miles/kwh going normal commuting speeds anywhere from 35 mph to 65 mph. I drove normal like I drive my ICE, not crazy hypermiling but a little accel downhill and slowdown up the hills. The kicker is on the way home my average dropped down to 3.1 because of hellacious headwinds and I stopped to charge out of caution, though I probably would have made it. I ran some errands and had a little bit of a heavy foot on my lunch break, otherwise I could do my 70 mile round trip easy peasy on my 28k used Leaf! Hope this helps you decide. At an average of 4 miles/kwh I could have done 80 miles on a charge today taking out my little charge session. The last 5% of my commute home I explored the full throttle range and drove around the block several times to burn off some watts so I could hit turtle, also. And it was 32F this morning when I left for work. All in all today made me super confident in my decision to buy this car.

e: I also ran 240v wiring and wired my 14-50 plug tonight :)

Yes. They balance as they reach 100% indicated charge. They also seem to balance a little at 80% charge.

The dash estimates are always too long. The best theory I've read on that is that they are based on the Japanese 208 volt power grid.

Looking at where my box is and the way my Hall down stairs is laid out, I think I'm going to cut 4 6" holes and run my wire out to the garage, with the 6" holes as my ceiling access to pull wire. Then I'll install 6" can lights in my Hall and get rid of the surface mounted "boob" light fixtures. :D I've wanted to put cans in the hall anyway, so now I have another excuse to do it and kill 2 birds with one stone.
Just gotta wait till after taxes and till I find out a little more about what they're doing about charging EV's at work.

Oh wow! Man, the left hand doesn't know what the right hand is doing at my company! The electrician was apparently given the order to get 2 EVSE parking spots set up at the other maintenance facility when he gets back from his vacation. Our general manager told me to fill out a facilities work request and he would back my request to get a couple EVSE spots at our building too! Nothing is concrete until it's installed, but man, that's great news for me! Once I see them install gear at work, I'm going to start pulling wire and get ready for my home EVSE! I'll probably wait for a used 16 to hit the market or look for a killer deal on a new one since the sales on 24 kWh and 30 kWh cars will probably drop off because the Bolt is out now.

What do you mean by based on the 208 power? Dang near all of our commercial stuff in the States is 120/208 and 277/480 3 phase power. If you live in an apartment it's most likely 120/208 power as well.

Right, but the Leaf was designed and first built and tested in Japan. It's likely that the charge estimate was just never reprogrammed from the Japanese grid-based estimates. The estimates are much more accurate when voltage is assumed to be 208 instead of 240. (I assume that the 120 volt estimate is derived from that 208 figure as well, halved.) BTW, I think some commercial US applications also use 208 volts.

Nice! Congrats! I just got the go-ahead to charge at work too, that gives me so much more freedom!

I think what Leftie meant is if the time to charge is based off 208v instead of 240v, which means basically anyone charging at home, the time will show too high. Yes you are correct, basically all commercial and many apartments are 208v, so if you pull up to a commercial L2 EVSE it should correspond pretty well to the listed charging time. Oh BTW Leftie, commercial 3 phase power is still 120v(not 104v) the reason you don't get 240 from two of the 120v legs is the way the stepdown transformer works.
Commercial 3 phase power:
120v, 208v or 277v, 480v for some larger draw buildings. Note buildings that have 277v/480v will also have dedicated transformers that step that power down to 120v/208v.
Home power is single phase 120v/240v.
