I finally got my Electric Bill and some answers about how the whole set up works. I have PV Solar for my house, but the Car Charging port is on a separate meter and only that separate is billed at time-of-use rates. Turns out I'm selling the excess power I generate at almost 14 cents/Kwh, which is fine, but less than half of the Peak rate of 33 for the time-of-use. I doubt I can get the other meter on time-of-use, but I'll give it a shot.
I've heard this week that some owners are complaining about the remaining mileage meter and its large changes. I can understand some of the concern, but I'm not overly surprised. The car has a Miles/Kwh gauge that goes from 0 to 8 to track your current usage and shows the average which varies depending on your driving habits. If you are going up a hill, the rate drops to under 1, but going downhill you tend to be creating energy instead of using any, so the gauge tops out. Nissan has an algorithm to calculate this and they are tweaking it as they get better feedback from the cars. Hopefully they will be paying me a house call to update mine as they did for Cars.com. So far, the max I've driven on a 80% charge is 54 miles and the meter still read 12 miles remaining. I'm going to start more daily tracking including temperature and driving condition to see what kind of range I can expect in any given situation.
Let me know if you have any questions. This weeks numbers are below the fold.
Drove 240 miles and charging costs were $4.27. Average M/Kwh increased to 4.5, so we are getting more efficient in our driving. Equivalent cost for the replaced car would have been $32.18 based on the lower cost of gas of $4.157/gallon in San Diego. The cost per mile for the leaf is a little under 1.8 cents compared to 13.4 cents for the Honda Fit which was getting about 31 mpg conservatively in city driving.
