That won't give you how much actually goes into the battery though, unless you can figure out the charge efficiency. Then there's the actual motor efficiency. I think you should just hack your Jeep up and add some current and voltage monitors at the motor cables. You know, for science. The Greater Good (TM).I could either install a Sense whole-house power meter or replace my EVSE with a ChargePoint. I'll do one or the other at some point.
