Tools Update · 26 June 08
Just wanted to post a quick update about some changes to the EV Calculator. A number of readers were wondering how hard it would be to add driving cost to the computation and it turned out to be relatively easy.
So now, when working on an EV setup, you can add the kilowatt hour rate from the local power company, along with the typical commuting miles. Under the Range sections it will show the cost per mile at the various gears/speeds, along with the total cost of the commute. Of course this is still only approximate values, meant for “what-if” comparisons and rough analysis of EV setups.
I have the values default to the U.S. average as reported here and 20 miles for the commute. Follow that link to find the average electricity cost for your state (or pull out an old electric company bill) and give it a try.
