He said Chargepoint at work.
ChargePoint does provide a QC, i.e. which some just call a charger, right?

They do, but so far as I know only profit seeking businesses have bought them. Workplaces and private homes install L2 EVSEs

Yes, you're correct. It's unlikely that a QC was there or near a work location.

A QC might be nearby but its use is expensive and probably not convenient for a person going to work. And he did say *at* work.
So lots of reasons to presume L2 charging.

Expensive? Time is money. I typically don't have more than 10-15 minutes to waste for a charge, and NEVER use a L2 except at home.

Most commuters park their cars at work during work hours. Does this mean you don't work out of your office?

Update on new battery after one month. 82.09 AH 363 GID's, SOH 103.20%, Hx 96.82%. 46966 mi. with just over 2000 mi on the new battery.
I had the software update done in late June but it appears that it was already done when the battery was changed. I haven't needed to to do a DCFC yet so I can't comment on charging rates with the new battery. Only real difference I see is that some regen is available at all times. I get one circle of regen available by the time I pull out of the driveway and LeafSpy says it's working. 3 circles by the time I'm down to 97% and all 4 by 94-95% down.

Battery health has actually improved slightly over the last month. I suspect that is due to the BMS learning the new battery. I expect it to take at least a year to see if the software patch actually does anything. I'll keep posting periodically for everyone's benefit.

Update on battery. After two months of hot weather there doesn't appear to be any deterioration. Stats are 363 GID's 82.04 AH SOH 103.22% Hx 96.15% 0 DCFC 55 L2. 2696 mi on new battery 47725 mi on the car. Hx has dropped by 1% but that's the only change I see. I still think I need to see a year's worth of data before I have any real confidence in the new battery and the software change.

Great initial report but what is farthest you have driven? Largest DoD?

Unless you pop off a 110 mile run, we hold judgment. ;)
