Re: Portable 120/240V KWH meter for your portable upgraded E

Tue Aug 30, 2011 11:10 am

Search ebay for item number 280654683754 - that is the one I'm using. All you need is this meter, three 12 gauge wires, an L6-20 plug and an L6-20 receptacle. For outdoor use, it should be inside a weatherproof enclosure. The total cost to me was just under $50. ;)

He has a similar LOOKING model, but if you read the add carefully, it now shows as "50hz", and for a KWH meter, that may not work at 60Hz. Thats what I was finding on eBay, all of the Chinese sellers now only seem to have 50hz model KWH meters.

This seller claims his is 50/60Hz, 10A calibrated (40A) max.. similar pricing if you add shipping.

FYI, the part # to search for is "DDS238-4"

Yet the picture shows a 50Hz model... It may make no difference but who knows...

How about one with remote sensing and data logging that can handle 500V DC and up to 300A?.. that one would be interesting.

Battery Pack DC Voltage and charging current?
The SOC meter shows those, and kW (but not kWh).

Usually 300.0 to 500.0 volts, and 0.0 to 99.9 amps.
Those should cover the QC V&A.

Yes, good idea, but you need one that can measure DC Amps, which is a different animal. Probably the place to actually install this would be inside the Leaf, for AC monitor the 2 AC wires comming of the J-1772 port, for DC, you would have to monitor the 2 DC high current pins on the DC port. Logging the data in the car means you have a running total, and only need 1 meter. connecting it to a data logger where you could input where and when a particular charge was done would get you even more info.

You would need a Hall Effect Sensor meter for that. It is a different animal from a current transformer AC meter...
