Does latest software update limit Model S to 17A on Blink Chargers?

Ran into this on day two of my cross-country Model S trip. Is anyone else seeing a 17 amp limit on Blink chargers that are rated for 30 amps? This is leaving me 100 miles short on overnight charges, meaning two extra hours at RV parks each day. (my 70A "mobile HPC" is going to get a lot more use than I thought).

God, I hope not, but blink does seem slow to me as well. I just assumed it was because they charge by the hour, not the watt hour.

I have charged at 2 or 3 blink stations this weekend at 30 amps each time. I was receiving about 17 or 18 miles per hour of range.

I got 30A at a Blink charger.

There was a problem reported with some Blink chargers a while back. Something about a bad crimp, which caused them to overheat at higher amperage. Maybe they have adjusted the bad stations so that they would only charge at 17 amps.

I'll try to find a link.

I also got 30A at a Blink charger yesterday, so it's probably only certain stations as DouglasR suggests.

It now appears that my S may have a charging system problem, possibly with one of the two 10kW on-board chargers. It is also limiting to 40A when charging from a 70A Roadster HPC. So the problem may not
be the Blink chargers, rather the car itself.

I had issues with a blink chargers this weekend. first one was non-functional. blink ran a diagnostic on it and confirmed it was a bad (never been used) charging unit. Second unit stopped charging the vehicle after 5 hours. was only charging at 17 Amps as well. Tesla Atlanta was extremely helpful and getting me to another charging station

So it may not be Blink in this case, but here is the link to the Blink problem: http://www.plugincars.com/honda-fit-ev-overheats-blink-charger-126246.html

I just used a Blink yesterday and was frustrated that it only charged at 17 amps giving me only 7 miles/hour. And then it shut off after about 5 hours all on it's own.

I had a similar problem using a J1772. I did not push the connector in all the way and the car limited the charge to 16 amps. When I went to check up on it and shut the door a display message said connector loose, I pushed it in firmly and the car started charging at 30 amps.
This was the charger in The Venetian I dont know who made it but it was not a blink charger.

@RanjitC - yes, I saw the same thing with the mobile connector in a 14-50 plug -- it was glowing yellow and only charging at 16A. I looked closer and noticed the "cable not latched" message and pushed it in harder, and then it glowed green and went up to 40A.

@RanjitC @jat I also had the yellow/cable not latched message the other day after I inadvertently pulled on the UMC cable while charging. I removed and re-connected the UMC.

I've tried 3 different Blink chargers in Scottsdale, & all maxed out at 17 A although labeled as 30A. Very slow and frustrating. Another MS parked next to me was getting the same from his station. No errors about loose plugs etc.

Blink website's spec sheets indicate 40A in/30A out stations have adjustable settings for their output. It seems the installers are putting them at the reduced settings, perhaps at the request of the hosting property to maximize charging hours for revenue or reduce load on the property's system.

I have twin chargers & got full 70A from the roadster station at the Tesla store. With the low amps seen at Blink stations, I've pleaded with my condo complex to pick a high amp unit rather than the standard Blink units businesses have for PR.

Can others please clarify their city/state where they are getting full 30 A? It seems CA Blink units are consistently full power.

My 17 amp Blink experience was in downtown San Diego at the Petco Park garage.

I called Blink to inquire about the slow charging. In summary, they said that other EV's are heating up the charge cables so they reduced the amps on all chargers even though thousands of Tesla's have charged with no problems. Here is the full response I received:

The EVSE or Blink sends a signal to the car over the Pilot Control line telling the vehicle how much power the it can supply the vehicle. We reset the commercial units in the Phoenix area to 16 amps down from 30 amps. We have had several complaints of cord sets heating up and vehicles stopping a charge session after 30 to 50 minutes. Most of these involved the new Honda FIT, 1 RAV4 and 1 Ford Focus. We are looking into the problem but until we understand what is causing this issue the decision was made to turn down the amperage from 30 to 16 amps on commercial units. If he plugged in to a unit then it is normal that he only pulled 17 amps. Until we understand why some vehicles on some units are generating so much heat in the power pins we want to insure there is no way the vehicle connector can be damaged or in your case the adapter cable connector. While we have a couple of thousand charge session with the Tesla with no heat issues the problem is we do not know what vehicle is plugged in at the time so we have to limit current for everyone.

I routinely charge at a public access Aerovironment EVSE-RS “Dual” charging station. I've always received the full 30 amps., there has never been any heating of the charge cable or connector and the unit has never shut down before the charge was complete. Looks like Blink has some engineering work to do.

Thanks @JZ13 for researching and providing that answer. Almost all the public stations in Phoenix are Blink unfortunately. I hope they resolve this soon. In the short term the staff at the Fashion Square Tesla store will be coming out to the garage often to hook me up to the roadster chargers.

My complex was planning on installing a Blink unit soon, hopefully I can talk them out of it. I'll pass along the email you received.

Thanks!

Actually I was in San Diego but the tech that replied to me must have confused my location as Phoenix. Anyway, it looks like you want to stay away from Blink if you need a fast charge for now.

I had to laugh when thinking that Blink was turning down the amps, but not the cost. Think of that when paying by the hour.

I charged at my brother's home with the NEMA 6-50 and while it started at 40 amps, his electrical equipment running reduced the Tesla to 25 amps. I had to unplug, close the charge screen on the touchscreen and then restart the charging process after manually raising it from 25 to 40, then plugging in. It stayed at 40 amps from then on.

I was told by the parking garage attendent that every two Blink chargers share one single 40 AMP service so to maximize the billing and parking fees. If this where true, then when charging alone you would get the 30 - 40 amps, but when a car is in the spot next to you at best you get 20amps.

I charged our Roadster at two Blink stations in Portland OR on March 6th at 30A, then at one of them again on March 9th, also at 30A. So, either they haven't done this to all stations, or it's taking a while to roll it out to every station.

What a mess. We can get a full charge overnight at 208V/30A, which is perfect for our trips from Seattle to Portland, but 208V/17A won't get the job done, and as others have noted, costs twice as much.

I'm planning to drive to Portland and to stay at the Heathman, which has Blink chargers in its garage. I have written to Blink to determine whether I can charge at 30 amps there. I will report back if I get an answer.

They answered me very quickly. The stations at the Heathman have NOT been adjusted from the default 30 amp setting. According to the representative, they have adjusted only those stations that have demonstrated an issue with overheating handles while charging. Blink support is available 24/7, so if you know you would like to use a particular station, you could call or send an email.

"All our chargers aren't on the Blink."
Um, OK.

Here's an update from Blink:

As part of a routine test, select Blink charging stations were set below 30 Amp. That test is completed, and except for a few isolated chargers, are all back to 30 A.

That's rather a departure from "all of our stations have been adjusted down to 17A."

Did they cut their $/hr rate with the current or is it $/kwh?

Thanks guys & especially @JZ13 for the research. Going from LA to San Diego tomorrow and am depending pretty heavily on reliable charging. Hope we get 30A!
