That's about 14 kW. Do that for three hours and you have 42 kWH.

Right. 14 kWh per hour. 60 mph = 100 kph. (Okay, 97 kph to be exact.) 
Divide 14 kWh by  100 km and you get 0.14 kWh per kilometer, as I 
said. Actually the AC charge is 0.2 to 0.3 because of inefficiencies 
charging batteries. It takes 0.3 to charge the battery and in the end 
~0.14 kWh is delivered to the wheels on the highway.
