How can I see how many KW the Leaf is pulling when charging?

I am (hopefully) a week or so away from buying a used Leaf. I currently have a Chevy Volt and a Bosch EL series 30 amp level 2 charger at home. The Volt's onboard charger only pulls 3.3kw, and the Leaf I'm going to get can do 6.6.

Is there a way to show the wattage that the Leaf is able to pull from my EVSE? Having never run it at the full 30 amps, I want to make sure it's working as well as it can. Can Leafspy show that? Can the onboard computer show it? Or will I just have to note the SOC and how long it took for a full charge and do the math?

Thanks all!

Leaf does not show. LeafSpy does.
You can also buy AC-current clamps and just measure :lol:

Thanks so much!
