Level 1 charging wattage usage.

Below is a graph showing the watts being used during a level 1 charging cycle.

You can see that near the end of the charging cycle that the wattage does drop off a little. The power factor was 1.0 when charging was occurring. The little blip on the end was when I opened the car door.

Good info.

That's cool! How did you collect the data?

I used a "Wattsup PRO". It's power analyzer and has data logger.
It records, voltage, amps, watts, power factor, and KWH.
You can down load the data to a PC for charting.
