Seems like a lot of charging sessions for 4 miles on the odo
The explanation for that came at today's EV event at De Anza College.
They demonstrated using a Japanese product that they are trying to get approved by UL that takes energy from the Leaf and drove their display booth (TV and t-shirt maker).
The battery in the Leaf is just being used for energy storage in a stationary mode. The Leaf is normally moved in a transporter truck.
This explains the low mileage but lots of QC (to get energy out) and L1/L2 to get energy in. I am assuming the QC increments independent of the direction of the current. I can look at the data I collected today to confirm this as they had to move the Leaf due to a water main breaking and flooding the original demo location.
