Cor, yes! Precisely I already have that model on my actual EV:

It works perfect on 240Vac; but on 120Vac everything seems to work
too (the LCD screen comes on and the Pulse LED flashes, which confirms the
power supply works too) but the watt-hour counter never advance. So, unless
I connect my EV into 240V the meter count will advance and keep the track of
energy used. When I use 120V; which I try to avoid most of the times but not
always is possible, I need to calculate the Kwatts poured in by tracking the
time being connected there.
I use this info to write it into an excel file, where I also put the
ODO trip information every several days or every month, and my monthly
utility bill. Then I get my Kilowatt per Kilometer usage, cost of kilometer,
max-min efficiency days/trips, etc.

David, that is exactly the point of use a Watt-hr-meter inside the
car; to have a Kilometer/Watt-hr track no matter where you plug the car
(this includes not using an EVSE). This way you will have an any time true
power consumption of the car either it is used on lights, driving, radio or
anything else, just like the Odometer of all cars as an indicator of all
Km(miles) used for the life of the car.

Marco
We have integrated watt-hour meters in to some or our EVSE units. 120, 208
or 240VAC is not a problem nor is a design for 100A RMS. The system we
have used also measures voltage, current and power factor. The current
measurement is used in the EVSE to stop the charge on over pilot current
situations before the main breaker trips and keeping the EVSE operational.
On the EVSE side you know how much energy is getting used and it can be
tracked by user or vehicle.
I had not thought about using one in the vehicle but it might interest some
people to track miles/watt-hr.
If anyone else is interested please write.

Subject: [EVDL] 120-240Vac Watt-Hour-Meter...
Im trying to find a Watt-hour-meter that can work on a single phase
either for 120 or 240Vac. Similar to this one from EKM-Metering: (can retain
cumulative watt-hour data)
http://www.ekmmetering.com/basic-kwh-meter-100a-120-240-volt-3-wire-60hz-ekm
-25ids.html
Want to install it on an EV conversion that will be capable of
recharge either on 120Vac or 240Vac (L1 or L2) using a J1772 inlet, so no
wire or manual configuration must be done. This will let me the ability to
connect the car on any 120 or 240 outlet as any L2 public charging and have
a track of all life power consumed from the car.
Does some one knows any different option?
