Anyone looked into the power factor of the charger on the Bolt? I've hooked mine to my Egauge power meter and it showed a power factor of .73 at 30amps. I know switch mode power supplies look inductive and most expensive switch mode supplies use some sort of PF correction. The cheap ones like used to charge your cell phone simply charge a capacitor at the peak of the voltage swing and I'm starting to think the charger in the Bolt is just that way.

All I've got is a cheap amp clamp and this egauge metering system. Does anyone out there have the proper equipment to measure power factor? If it is as poor as I think, placing a capacitor across the down stream side of the EVSE contacts could help my power bill a lot.

If my calculations are correct (and they may not be), I think a 6200uf capacitor will give kVAR of ~2200watts and get me to .9 power factor.
