Charging Interrupt By Utility?

Sun Apr 24, 2011 2:22 pm

When I went out to the garage this morning I happened to notice that the Blink had a message saying that charging had been interrupted by the utility and would recommence at 11:51 AM, which was a couple of minutes later. It was not charging but in fact it did restart in a couple of minutes as suggested by the message.

Any idea what this was? I haven't seen anything suggesting that the utility could interrupt charging.

I had a similar experience last Friday just after the Blink was installed. The LEAF was being charged (no timer setting) when I received a notice of a short interruption which stated the time at which charging would re-commence. I waited and watched the Blink display. Sure enough charging restarted at the indicated time. My utility is PG&E in northern California. None of the power in the rest of the house was interrupted so PGE must be able to monitor the charging dock. I have a "smart meter" on my electrical panel. Maybe that gives them access to the Blink and the charging dock through smart meter or my internet connection to the Blink website.

Odds are you just experienced a software glitch. You'll know if you participate in "load-shedding" or not and things need to be set up in order to do that.

I've looked in the Blink and can't even find where a load-shedding lead would be attached...

My utility is SDG&E. Like linkim I think that every other electrical everything in the house was working normally. I'm thinking the shutdown had to originate on the Blink network side. Yes I have a smartmeter but the Blink just runs from a couple of 40 (20?) amp breakers. I don't have a second meter. In fact SDG&E hasn't gotten around to spotting it yet. Basically I just don't see that SDG&E has a mechanism for interacting with the Blink through the panel.

I'm guessing it's some "feature" we don't know about and Blink and/or SDG&E was just testing it. I can't confirm this since I don't know how long it was shut down, but I don't think it was for very long. Plus at 11:00 AM on a cool Sunday morning I can't believe there would have been a lot of electrical demand.

This isn't a big deal but I wouldn't want it to be standard practice. Even if the car is fully charged, if the charging stops and then restarts, the battery will be charged for a short period. This seems like exactly the situation Nissan warned against as shortening battery life -- constantly charging a battery which has only been slightly discharged. Not cool.

I agree with DarkStar in that you experienced a Blink software bug. Many such bugs have been discussed on this forum. Just do a search.

I know that SDG&E is not participating with Ecotality like this. I'll put a lot of money its a bug or public testing.

Either way sad stuff.

With PG&E... Saw the same message myself for a short time. Either a prevalent glitch or they are doing remote testing...

Has anyone reported this to Ecotality? What is there response (if any)?
