Thanks everyone that sent me a recommentadion. Cor, I actually
contacted EKM Metering some weeks ago; and a tech guy just recommended that
one you say. But yes, once you get all pieces together it results quite
expensive for the intended purpose (to be inside of a car and use it only as
a kilowatt hour meter) nothing else. This EKM solutions includes lots of
other things ideal for a stationary solutions, not mobile that I will never
use.
I think the best and cheapest way to go, as Russ Sciville said; is
to use a common domestic meter. Not the nicest and space saving option, but
useful.
Actually, with my basic EKM US$90.00 solution
(http://www.ekmmetering.com/basic-kwh-meter-100a-120-240-volt-3-wire-60hz-ek
m-25ids.html) I can track all power poured into my vehicle as long as I
connect to 240Vac. And only at emergencies when running out of electrons,
that I'm forced to plug my EV into a 120V outlet; I lose metering those watt
hours. For correcting that, I use to write a log on a notepad every week or
month, take those numbers to an excel file and then make the kw/hr
adjustment considering a known cost per kw. Anyway, that notepad is the one
I use to have an exact cost of my driving.
Thanks...
Saludos..!!

I saw this meter used in an other application where it will get either 120V
or 240V and it is actually spec'ed to work that way:
http://www.ekmmetering.com/ekm-omnimeter-i-v-3-universal-smart-meter-sin
gle-phase-or-3-phase-120-to-480v-50-60hz-up-to-5000-amps.html
Note that it does require a single Current Transformer and it has insulated
signals for pulse (metering) or serial communication.
It is not cheap but does the job well.
Another variant of this meter is used in the new JuiceBox versions.
They use the UL approved version of this meter.

Subject: Re: [EVDL] 120-240Vac Watt-Hour-Meter...
Where did you read that the meter does not work for 120VAC? The description
for this meter:
http://www.ekmmetering.com/120-240v-package.html
says: "This metering package includes everything you need to meter 120/240v
electrical systems and to send your meter data to the cloud."
And it has piercing connectors for neutral as well as the two hot leads.
Seems it should work.
I have an EKM that is 5 years old and it works similar to yours - doesn't
record on 120VAC - but it does not have the separate current transformers
nor pierced neutral that the above meter has. I would email or call EKM to
check. Not recording on 120VAC is not a problem for me since I never use
120VAC.
