Re: Steady State Vehicle Charging Fact Sheet: 2015 Nissan Leaf

I understand the percentages, I am guessing that includes the overhead losses from the pumps running as well or is this only the onboard charger itself?

Otherwise it should look like this, correct?

To add 20kw to the battery with...

120v stock EVSE with 6.6 on board consumes 25.64 kWh
120v stock EVSE with 3.3 on board consumes 23.26 kWh
240v 3.6 on board consumes 22.35 kWh
240v 6.6 on board consumes 22.10 kWh

They account for numbers from the wall vs coming out of the Leaf charger module. They don't account for losses elsewhere inside the Leaf such as:

* vampire drain by 12v or other user loads (radio, dash, cabin lights, headlights, heat, AC, OBDII adapter, etcetera)
* BMS overhead / battery charge inefficiency (load balancing, battery charging losses)
* Battery output losses

anything else I missed. They were just testing the J1772 port + internal charger and didn't test past that module.
