tracking charging costs

[Coffee_Slurry]

Efficency=AMPK /DMPK
DMPK was recorded from energy screen that is reset daily with trip meter

DMPK is a made-up bogus number from the highly-massaged synthetic imagined state of the undocumented internal states of the car display computer. Basing any calculation on it results in more junk math.

Unless you're using your own calibrated CT or something.

ok have meter installed to monitor 240 charging so hope to have some better efficiency #'s. the meter is analog and has a 1 kwh resolution so its going to take a few weeks to get a number. did not charge it to 100% last night so will do so tonight and report back in a few weeks

For my first full month of having a second meter in and charging exclusively on the Blink, I paid $18 for the month. I did not write down the mileage at the beginning of the billing period, but did capture it for this one. It was roughly 500-600 miles. $18/500 = $0.036/mile $18/600 = $0.03/mile. Next month I will have an accurate number.

To me CARWINGS stats don't matter, Blink stats don't matter. How far did I drive, and how much did I pay? Simple.

+1 All I'm doing is taking note of how far I've driven the car and the KW consumption from my separate SDG&E meter reading, to determine my cost per mile driven. All that other data from Blink & Carwings is just obfuscation, imho.

Looking forward to your results.

$43-Where did you get the meter?

I assume you couldn't find a kill-0-watt style (in-line and portable) 240V meter?

i found a few digital inline plug in kind, but they all required at least 2 adapters. not worth it, plus they were all English and not even sure where i would have gotten the adapters to begin with.

got the glass meter at a place in FL

was $17 for meter, 11 for backplate. $15 for shipping. came in 2 separate boxes. kinda sucks. figured they pack them both together, but...whatever
