I was reading posts about how the level 2 charger is supposed to be like 10% more efficient than the level 1. I run my level 1 charger through the Belkin WeMo, which tells me the energy usage. I've confirmed this with the RainForest device that talks to my smart meter, and further confirmed it by logging into my SDG&E account and looking at my usage. The level 1 charger costs 1.2kWh per hour of operation. It takes me 12 hours of charging to gain 52.5% of capacity on the battery. The battery is suppose to hold 24kWh. 52.5% of that is 12.6kWh. So, I supply it with 14.4kWh of juice (12hours*1.2kWh/h) to get 12.6kWh of charge. That's an 87.5% efficiency of energy transfer.
My question is, has anyone run this math for their level 2 charger? It's hard to believe they're getting 97.5% efficiency transfer, but I'll believe it if I see the numbers.
