I sooo need to do that myself!!

I hooked my blink unit to a dryer outlet style plug. Just make sure to leave your unit on some nights to make sure it can phone home and get the firmware updates and report its data. As the Blink team works to fix bugs the next several months of firmware updates are going to be really important.

FYI, I checked with Blink support about the power usage, and Robert Nowaczewski e-mailed this calculation:
A working unit when it is just sitting doing nothing the unit pulls about 0.2 amp at 245.7 volts AC.


Power is V X I = 245.7 Volts AC x 0.2 Amps AC = 49.14 Watts.
Multiply 49.14 Watts by 24 hours and divide by 1000 = 1.17936
Next Multiply 1.17936 by hourly rate for example (15 cents per kW) = 0.176904 cents per day
Last multiply by 365 days a year by 0.176904 to get $64.57 a year to have blink connected and sitting in garage or roughly $5.38 a month.

This will vary with your rate in your area. The unit basically uses a little less than ½ the energy of a 100 watt incandescent bulb.

As to a ‘stand by’ or ‘sleep’ mode: This has been a common request for a future update and it has been added to development’s list of improvements to be rolled out in the future. At this time, there is not a ‘screen saver’ or ‘resting’ mode.
49 Watts! :shock:

EVLover thanks for the calculations. I just got my Blink installed. I measured the standby current of mine using a clamp on Triplett ammeter from Frys. I got 0.10A. After the 1.6 firmware upgrade, it remained unchanged even when I configured it to turn off the display. I am not able to measure power factor so that might reduce it a bit. Remember for those who have TOU metering, the "vampire" current is charged at varying rates during the day. At peak rates, these can be upwards of 0.38 per KWh or so here at San Diego. We're not talking big money here of course but it does bother me that it is wasting 24 watts of energy, seemingly unnecessarily.

I highly suspect he's not measuring power factor - many others have and are reporting 10-16 watts at idle depending on firmware revision.

Residential customers don't get billed for reactive power - only actual power usage.

The only meter that matters is the one SDG&E reads, and that one says 10-12W after the upgrade (depending on dimming options).

Put your hand on the top of the case. If it was burning 50W sitting there, it would be warmer.

GroundLoop: How did you determine that the SDG&E meter was registering 10-12 watts? I am interested in doing that myself but I have a smart meter and it is difficult to determine instantaneous power. Google power does not work yet on my net metering for Solar PV.
Thanks.

That's more than 1/4 of my current (pre-leaf) electric bill. But it's actually worse than that. The standby power is running 24/7, and I will be getting the EV rate.

So it's like 49W*$0.25*18hrs + 49W*$.05*6 hrs=~$7/month in the PG&E service area.

And to add insult to injury, I will be working hard to only use power for my Leaf during the off-off peak time, but I'll be forced to use a non-trivial amount during peak time.

We need a more power efficient stand by mode, that's for sure.

The Blink actually "only" pulls 10-15 W when idle depending if the screen is on or not. Or about $2.14/month using your rates.

Still would like to see the vampire draw down to 5W or less... 15W 24/7 for 30 days is enough to drive the LEAF about 40 miles!

Boy is that different than what I measure with my TED. Before the dimmer version of the software, I saw 12 watts in quiescent state. Now, with the dimmer activated, I see about half that. I'm sorry, but I refuse to loose any sleep over 6 stinking watts!
