Hi Bruce and All, EV charger congestion, what a great problem to finally have ;^P It'll be solved soon by more chargers everywhere. Especially with the insane amounts of money the charger station companies are getting for each from the gov. Too bad they couldn't just put in dryer plug that won't turn on until the outlet door is closed for a fraction f the price . I think soon there will be aftermarket generators, very light, eff like Lotus' Range Extender at 35kw in 115lbs that you put on a trailer hitch. Also as more EV's come along most everywhere will have charging stations lowering having to find a open one. I was recently comtemplating a trip to Daytona Bike week from Tampa and there must be 30 level 2 chargers along the way. Though other Fla areas have gaps like up the west coast. A big problem is the production EV's most of which are overweight, overpriced and over teched thus need lots of juice, battery. Since my just getting roadworthy EV MC chassis only uses 240lbs of batteries it only takes 1.5 hrs on a 120vAC outlet to charge 75% as few run down their batteries al the way and I don't. Later it'll have a full aero cabin body. And working on a faster one. Also building a Range extending generator from scratch, even building the alt from the magnet rings of a Etek PM I burned up. It'll put out 4.5kw and be Cal emissions approved on the motor and it will be special tuned up on top of that. Every building, service station, RV park, etc has power. But only lightweight EV's can benefit from a lot of this I've been driving and opportunity charging for 15+ yrs now without a problem well before charging stations came just last yr. I've found all parking garages have outlets I've asked and fast for mine but heavier ones of course take hrs to charge for many of these. So the answer is all of the above and demand lighter, less expensive EV's!!. Jerry Dycus

Sadly, it is seems to be the West Coast that has the growing pains first. But that may change once the U.S.A. made Leaf EVs are in production. The are other EVSE growing pains that are not discussed: the unevenness of installations. EVSE company sales teams are hot to make a sale and get their commission, but prioritizing a contiguous string of public EVSE between cities is not their focus. As I look at all the level--3 (l3) quick charging on EV Charging finder app/sites, I see WA and OR are light years ahead of CA. One can easily drive Electric from Canada down Hwy 5 through WA and OR, but when it gets to the northern CA border, there is a huge gap of l3 (and even l2) EVSE points. Tesla EVs with their greater range, have not problem traversing the EVSE-void, but the more affordable EVs targeting a 100 mile range will. The NRG deal that CA Gov Brown signed has not kicked in yet. A reply to my inquiry as to when NRG's eVgo is going to get their act together and start installing public EVSE as promised was a 'wait and see'. I hope eVgo knows to start at the northern CA border and install l3 along Hwy 5 going south to Sacramento. And then fill the huge l3 EVSE gap between Silicon Valley and Los Angeles along Hwy 101 in the same manner that AeroVironment made their installations (one L3, and one L2 with room for growth at a future date). And lastly to do the l3 installations on Hwy 5 south of Sacramento down to LA. If the eVgo l3 installations happen in that order, CA will have a contiguous l3 route, same as WA and OR have (from north to south) before all of the aforementioned installations are completed. Here's another issue: While 100 miles is the target, many of today's Production EVs are not rated that high, most closer to 75 miles. And of the 75 miles, that is from 100%SOC down to nil (just before bricking), which is not the way an EV driver typically drives or ought to driver their EV. So the rating is a bit bogus as once you start driving an EV, you usually do not drive it from 100%SOC down to just before bricking (0%SOC). Since most drivers are going to want to be protective of the life of their pack, we all know charging to 80%SOC is a good stopping point. The Blink l3 CHAdeMO EVSE allow the driver to enter in how much of a charge they can get. Up to 80%SOC is the quickest / takes the least amount of time. But a driver could select a charge that is higher that would unnecessarily block that l3 spots while they do the much slower charge rate. I would hope as EVSE crowding occurs, Blink would allow the host to limit l3 use to only 80%SOC, so that anyone wanting a 100%SOC charge would move over to the slower l2 EVSE next to it. The AeroVironment l3 installations in WA and OR also have a l2 EVSE next to it. This frees the l3 up for the next driver to charge up to 80%SOC quickly, and get back on the highway. This only charging to 80%SOC has reduced the range, and if you include the normal 10 miles of safety (to fin the EVSE or turn around because you missed the turn off), most 75 mile range EVs would really run between coming in with 10 miles left, and charging to 80%SOC (60 miles). That means, l3 installation planners need to install them less than 50 miles apart. It also means it would be wise to have home or portable EVSE that the driver could select to only give a 80%SOC charge, thus protecting the life of the pack. That's my thoughts.
