Tony's idea of staying overnight while trickling up to 100% is a good one that would minimize demand on charging infrastructure. Obviously, that probably won't work for everyone without some planning - not enough L2 infrastructure!
Really the biggest issue is that while there are a good number of QC locations now, all of these locations only have a single QC which becomes a bottleneck.
Let's say just 50 LEAFs decide to make the trek from San Diego County to Long Beach the same day - somewhere between 70-110 miles for a total of 140-220 miles. That's somewhere between 1 full charge to a bit over 3 full charges required to make the trip (assuming one starts with a full charge). If QCing to 80% and starting with 100%, people in north county will need at least 2 QCs (~60 mi + ~45 mi + ~45 mi = 120 mi), people from further south will need 3-4 QCs.
San Juan Capistrano will be a popular spot to stop being 25-65 mi away from San Diego, but only one plug and 25 kW max. It's about 40 miles up HWY 1 to Long Beach from there (so only about 70% charge needed), but then you have the issue of getting back.
If taking I405,
Quail Hill will also be a popular spot being 40-80 mi from San Diego. But there are reports that this is also a 25 kW station. At least there are 3 L2 stations here, too. You'll have about 30 miles to Long Beach from here, so only a 60% charge needed.
Next along I405 is
Connell Nissan. Only 13 mi up from Quail Hill, so should be reachable from north SD County. Now this is only 25 miles from Long Beach, so a 80% QC here will get you to and from Long Beach with a new LEAF and/or a bit of hypermiling.
Another option might be to take I5 through Tustin stopping at
Tustin Nissan (50 miles from north SD County, also 25 miles from Long Beach).
Woodbury Town Center is not far from here and also a good
But because there's only one QC at all of these locations, you're not going to move much more than 2 cars through each location an hour. Just shuffling 50 LEAFs up there is going to mean 25 hours of QC, assuming optimal use of the 5 QCs and 50 LEAFs, that's a 5 hour spread (10 cars per QC station) to get all the cars there with enough charge to start heading back. 30A L2 capable cars will be useful if there are nearby L2 stations - a 2-3 hour L2 will be equivalent to a single QC. Even on 16A 5 hours is good, but what do you do for those 5 hours? I suspect there will be a lot of mini-meets near the popular charging spots while people hang out waiting for a charge!
Potentially useful equipment:
EVSE upgrade with
adapters - for use in a pinch if you get stuck somewhere without a charging station.
J1772 Hydra to split 30A EVSEs into 2 plugs for 16A limited vehicles.
J1772 Adapter Box - will let you use your
EVSE upgrade as an extension cord for ICEd or otherwise blocked charging stations.
Easy240 or
Quick220 - Again, in case you get stuck somewhere in a pinch.
Tony - when/where are those other QC stations you've mentioned in the past going in?
Having some sort of dedicated message room/board or something will be useful for getting near-realtime info on charging station availability. The cautious traveler will give themselves plenty of time to make it for the 9am start!
