Thats right, I've now been driving Nissan Leaf for 3 months. Unlike what GM would have you believe, I've not been stranded ever - nor miss the smell & noise of the fossil fuel cars. Nissan Leaf has been an unqualified success.

So, how much does it cost to drive Leaf ? That is one of the questions I get asked regularly.

I've been noting down a lot of stats everyday about my Leaf driving. 3 Months is a good time to take a look at the collected stats.

First, let us see how I collect the stats. Leaf shows quite a few stats - the important ones I use are the the number of miles driven and the Miles/Kwh. I reset these stats before every trip. After the trip I note down these numbers and log them in an excel sheet. By trip, I mean starting from home and coming back home.

The other number I collect is the energy used to charge the vehicle every night. I've the Blink charging station - which keeps track of the energy used. I can see this over my intranet (yes, Blink is on the intranet using builtin wi-fi). I note this down after charging every night (or in the morning).

These two sets of numbers helped me compile the table shown below.

You can see the stats for 3 full months and a lifetime row at the top. Note that lifetime includes 5 days of driving in Feb, so is not the aggregate for the 3 months shown.

The first column gives the number of miles. The second shows the total amount of electricity used to charge Leaf - as shown by Blink. In the third column I've the average temperature for the month collected from a weather tracking website.

Then, we have 2 Miles/KWh figures. The first one is using the electricity used at the "wall" as shown by Blink. The second one is the "efficiency" as shown by Leaf. They differ by about 80% to 80%. That is the charging efficiency of the car.

The rate is the electric power rate I pay PSE, my utility. This includes the extra I pay to get 100% Green Power. This rate multiplied by the total energy consumed at the wall (second column) gives the total amount in dollars that I've spent fueling Leaf.

Yes, you read that right - I spend less than $20 a month charging my Leaf. That is about what you would pay for 5 gallons of gas.

The last column shows cents / mile. You can multiple this by the number of miles you drive per month, and you get an estimate of how much you will spend on fueling your electric car.

I've have a separate blog about the range and efficiency - but note that as the average temperature is increasing i.e. as the wether warms up, I get better economy from the car.

One other thing to note is that EPA's economy number for Leaf is 2.9 miles/KWh. As you can see, I'm beating it handily.

I've got a few questions to throw in. Hopefully not too many.

1. How about plugging it in? My friends keep warning me that when I get a Leaf, plugging it in every day will wear thin? Is that the case? Or is it so routine you forget about it?

2. How does 3+ people in the car affect range/acceleration?

3. Does it charge at a linear rate? Or is the first 70 or 80 percent quicker?

4. What kind of freeway range do you get at 70mph?

Thanks
