Jim S. – My Spreadsheet is Proof

I own a 2015 Nissan Leaf and keep careful track of the energy supplied to my car and to its efficiency. I added a 240 VAC power meter to my home charging system so that I can actually measure the electrical energy supplied to the car with each charge. My Leaf spreadsheet is available online at:

As of this writing, I’m averaging a gasoline car equivalent of 166 mpg, many times the mpg of a typical gasoline-powered car. Electrical motors are just much more efficient than gas engines and my spreadsheet is proof.

I have my Leaf set to be charged by 6:00 a.m., and when the batteries get down to roughly 25 percent, I hook the charger up in the evening…and never see the charger in action. I get up in the morning to disconnect the charging cable, and that’s it. By the way, the last charge was shown as 111 miles on the instrument panel, much more than Nissan advertises, and those numbers seem to be quite accurate.
