Some of the installations are not intended for the public, but unfortunately LADWP seems to have no written policy and has done precious little to publicize their plans. There is also a third DWP installation completed on N. Main St. near downtown which is only fleet accessible. They are starting design for one at the 110 and 5 Freeway crossing, and sites at USC and LAX are in process, the latter three intended to be available for public use.

Update on the UCLA site: the DC Quick Charge unit installed there by LADWP is publicly accessible...BUT only by paid permit parking at a flat rate of $12 to enter the facility where it's located (Parking Structure 4 just off Sunset Blvd. at Westwood Plaza). Furthermore, the facility is unstaffed after noon on Fridays, at 1pm Saturdays and closed Sundays - all other days after 5pm. Since there is no automated vending of parking permits, the general public has no access at those times.

Way to go, acadummies! Could you have sited it in a worse, less friendly location?

Recently on a trip to Sacramento State (CSUS) I did the pre planning to discover whether or not EVSE were available while we toured my alma mater and the school my eldest will attend in the fall. Turns out we all got up late and took our big Ford Flex gasser instead. But when I got there I was glad we had as the only evse I found on the tour was in a faculty only lot that my car couldn't have reached without campus security help.

Even though this is somewhat off topic... I bring it up here to inform you about the payment system the campus uses for paying parking via smartphone. It is called PayByPhone. The really cool thing is that once set up (and you know the zone number of your favorite lots) you can park... walk away and pay on your way to where you are going. It will text you to remind you that it is running out of time etc.

Sac State is also using it for billing time on their chargers. You pay for your parking and your EVSE access. This kind of smartphone app seems ideal for this app. With the right hardware hooked up to access gates it could allow secured access to chargers of all kinds... avoiding some of the vandalism and such that plagues anything installed in the public domain.
Wanted an EV forever. Now driving a 2013 LEAF SL. The car keeps living up to the promise, and CHAdeMO chargers keep extending my range!

Yes, but if you are venturing to San Diego in a LEAF, an 80% QC at either of these just barely gets you to Carlsbad where the next QC is (just over 50 miles). And leaves you a bit short if you don't have a fresh battery in your LEAF unless you are comfortable getting in below VLBW.

You pretty much have to stop at SJC to get into the middle of San Diego county. A QC station located half way between SJC and Irvine would fill in that gap.

My biggest worries when taking a trip where I need charging on the way are:

1. Coming across a station that is non-operable leaving one stranded at best at a nearby L2 station until one can get enough charge to get to the next QC - or worse - completely stranded.
2. Coming across a station that is busy (usually not too bad with a QC if everyone is behaving).

Universal City Nissan's Quick Charger has now been added to the ChargePoint network (as of April 3rd), whose logo is now prominently displayed. The fob reader has been replaced by a ChargePoint device reader sporting Visa, MasterCard, Discover and AmEx logos, which led me to believe the QC would only operate on a pay-per-use basis.

But it approved my ChargePoint card when I swiped it, which surprised me because I don't have any credit cards tied to, or credit in, my ChargePoint account - it is restricted to permit access to free charging stations only. I have no idea whether free charging will continue long-term, or if I was just enjoying a limited grace period.

A bonus (or demerit, depending on your point of view) is that the charging session no longer tops out at 80%. I charged to 90% before ending my session, but it appeared it would have continued if I wanted to reach 100%. I assume that is standard for the ChargePoint network.

Re: Quick Charge L3 in LA, San Bernardino, Riverside Counti

Last weekend we were happy to find that the 7 Eleven (Blink) QC in San Bernardino, just off the 10 freeway on Waterman Ave., has been back up.

However, it seems to be a trend that many QC units are set to shut off after reaching "80%" or "90%", numbers that continue to be inflated due to a LEAF software bug.

In our case, at the 7 Eleven, the QC shut off after no more than half an hour, at what the Blink machine reported as "90%". This translated to about 66% in gids on our degraded battery, or less than our car's 80% which now occurs at 67.6% in gids. As a result, we still did not have enough charge to get home safely and ended up making another stop to use the Blink L2 at the Redlands Walmart, at 3.3 kW since our LEAF is a 2011.

More and more, our LEAF is turning into a local-only car. With QCs not always reliable, incomplete charges, and yet another charging network that we'll have to join, we are finding ourselves taking the Prius more often. All of this continues to make me appreciate the overall approach that Tesla is taking, offering only vehicles with plenty of range, and making SuperCharging "free". The LEAF has a place in the market, but it's really best for local use only. The dream of regional mobility based on CHAdeMO quick charging has materialized to some degree, but it's not (yet?) what I'd hoped it would be.

On one hand, a QC right at the base of our mountain, in Highland, CA where CA-330 leaves the "flatlands", could make a huge difference to us personally. On the other hand, for a QC site to be relied on by anyone resembling the general public, it should possess multiple chargers, be available 24/7, and be priced no more than gasoline for a Prius. Basically, it needs to resemble a gas station (or SuperCharger site). I have to admit that it took me a while to come to appreciate the need for this approach. Of course, such an approach necessitates substantial subsidies from interested parties (car makers and/or government) and would be helped by lowering/eliminating electric demand charges for EVs.

+1!

Yep, that is why I consider single QCs to be worthless for any trip that is even remotely mission critical...

On the Blink, did you override the charge to stop at 100%? Do you have last year's P3227 update? Someone said that they noticed the car would continue to charge past 80% after the P3227 even after starting below 50%.

Definitely. Tesla made the right call by installing more plugs per location as it improves efficiency of the stations as a whole while minimizing risk of a user being stranded or finding all stations busy. As a software engineer, you would probably enjoy this thread: Capacity of Charging Stations Using an Erlang-B Model

Yes, something to help mitigate demand charges for EV charging would help a lot. But still, smarter charging infrastructure would also go a long ways towards minimizing those charges. Again, one just has to look at Tesla for a model.

Let's just look at the QC station around the I10/I215 interchange that you are near. There are 3 different QCs within 7 miles. All have suffered from various states of unavailability over the last 3 months while ringing up 50 kW of demand charges every single month they have been running.

Instead of scattering those stations around, wouldn't it be better to have all 3 stations at the same spot near the I10 / I215 interchange? Install a communications module that limits the maximum total demand for all three stations combined to 60 kW. If the comms module fails, just limit each to 20 kW by default so none are dependent on the other to function. As further backup and to assist non-QC vehicles, install 2 CT4000 J1772 stations.

Install these every 20-40 miles along major thorough fairs like the I10/I215 interchange. Now you minimize the cost of charging infrastructure cost to provide reliable regional mobility. To fill in the holes, add J1772 stations, but always install at least 2 and preferably 4 plugs per location. All stations should ideally be located near restaurants and/or shopping and/or parks to help pass the time if needed, be located away from prime parking and have parking time limits - 45 minutes for QC spots, 4 hours for L2 spots with perhaps provisions for overnight parking if desirable. Finally, all spots should be able to reach multiple parking spots to minimize the effect of being ICEd or other inconsiderate plug-in drivers who hog spots.

Oh well, one can dream.

So you're saying that you can't rely on QCs at all? I think there's basically only a few locations in all of the USA where there's more than one CHAdeMO station per location.

Yes, my LEAF had the P3227 update last year, and I explicitly selected "100%" on the Blink unit.

Thanks for pointing out that Capacity of Charging Stations Using an Erlang-B Model thread! I'd been away from the forums, and am glad you highlighted that gem.

I absolutely agree that areas like the 10/215 interchange would be better served by co-locating QCs. Great suggestion!! The only downside of co-locating QCs is that the user is more likely to have to detour to use one. For instance, I often prefer Fontana Nissan's location along the 210 freeway. On the other hand, I'd be more than happy to detour a few miles in exchange for reliability and availability.

Another consideration pertinent to the 10/215/210 area is that QC sites need to be in good neighborhoods. Late at night, we don't like using QCs at San Bernardino 7 Eleven stores because they often seem to draw sketchy characters. It's one thing to fill a gas tank in 3-5 minutes and quickly exit the area, quite another to hang around for 30+ minutes waiting for a charge. Somewhere around downtown Redlands would be more ideal, even if less geographically optimal.
