I'm confused by the numbers while charging.  According to the label on the Quic charger it has an output of 9A, but it is drawing 12.5A from the outlet (this seems too much of a difference to be inefficiency/heat loss).

Also - When I plugged both chargers into a 20A circuit I did not trip any circuit breakers - is the bike really drawing 25A from a 20A circuit?


WAIT - just realized that I made the assumption that the offboard 'Quic' charger is the same as the onboard charger (they were the same on my 2012). I'll have to repeat the Kil-O-Watt test with each charger separately. I'll try it later today.

Maybe the AC line voltage at the charger input is dropping significantly when drawing heavy current. In my garage outlet, the voltage drops from 119VAC to 112 at a 12A draw  (cheesy wiring).

BTW, I love these things:

I don't have much faith in the accuracy of the Kill-A-Watt meter when it is being used at high current levels.

I checked the Kill-A-Watt meter against the Belkin monitor that I also use - they are within a few Watts of each other.

But, mystery solved - the off board Quic charger does not draw as much current as the onboard charger (9A vs. 12A).

I'm still surprised that I haven't tripped a circuit breaker: 12A + 9A = 21A.

In any case I try to used a J1772 charger when I have a choice.
