Re: Mods for the Blink EVSE ! (was Fix)

Tue May 10, 2011 10:32 pm

I ran my Blink for the first time while reading data from the SDG&E meter, and it appears that an L2 charge draws a steady-state 3738 Watts. The fluctuation is very small.. 3735 to 3740.

My unit's standby/idle draw is 12.45W

Thanks for the tips however the breaker wearing out is not an issue for me since I am using an actual switch. The Blink replaced my old EVSE and this circuit still has an Intermatic 40 amp timer switch on it and I have been using that. The timer was used to charge off peak back when neither the cars nor the EVSE had timers built in.

That's good to hear :)
For other folks, it is possible to have a 2 pole snap switch installed, if that is your wish.
Your friendly union (yes, that was a shameless plug) electrical contractor will fix you right up.
cheers!

With it having standby power of <16 watts, as long as its not charging and is just standby power, what's wrong with just unplugging the cord from the 240V outlet? Why the need or desire for a 2 pole snap switch for the occasional need to reboot the Blink EVSE?
I'm not sure how often rebooting will be needed though. The first time I used mine it was failing to recognize that it was plugged into the Leaf, and I had to reboot. But only used it twice so far.

ECOtality could come and take away their Blink anytime during the project participation period. That's the risk. Part of the agreement states that it will stay connected (http://www.etec.stage.nissanusa.com/participant-agreement/form.php):
(g) Will provide and maintain electric power to the EVSE

For that, I plan on keeping mine connected... at least until December 31, 2012. :D

For the occasional need, absolutely nothing. For daily shutdowns like were being discussed, you will eventually wear out the receptacle. Which could cause arcing and other bad results.

Thanks, the occasional shutdown required for rebooting the Blink when it hangs up and quits functioning correctly as all computers do occasionally is what I was referring to.
I recognize eV Project agreement requires "continuous" connectivity.
I don't see much reason for shutting it off daily even after that requirement expires. Most computers have better reliability if left on all the time.
As discussed earlier in the topic, the standby power is pretty high on the Blink and probably could be markedly improved. The new software for LCD auto turnoff helped a bit.

I see the new firmware has an option to blank the display after a selectable time (5 min => hour). Anyone measure the power with this new firmware when the display is blanked?

Yes, that was discussed in on this topic: viewtopic.php?f=43&t=4059

What's everyone's experience with the Blink failing to recognize that it has been plugged into the car?
In about 10 uses I've had the Blink fail to recognize it was plugged in twice, and had to unplug the Blink to get it to work.
The last time it appears I might have plugged in while the Blink was starting some internet communication, and that its not configured correctly to do two things at once.

My Blink has never failed to recognize when I've plugged it completely into the car. There was one time it didn't seem to think it was plugged in, but I just needed to push it a touch more to secure the latch.

My blink has always provided a charge to the Leaf when plugged in except:

#1: The the Leaf's charge time is outside the time period programmed to charge.
#2: When the Blink is rebooting itself (this seems to happen every once and a while, perhaps for firmware updates.)
