I've been wanting to do an EV conversion for awhile but never committed to anything. The ever increasing gas prices and some research pushed me into realizing this isn't that crazy of an idea. I was originally thinking of selling my car and buying something even more economical but the car already got 26mpg commuting to work. So even doubling my mileage just didn't make up for the cost of a new Prius for example vs how much it would cost to convert my current car and how quickly I could recoup that investment.
I currently spend a minimum of $300/month just to get to work assuming I don't drive anywhere else. Cutting that cost in half with a Prius 20-30k would take awhile to pay for itself. The conversion I've estimated at around 6k. Monthly costs being about $30 in electricity. So in theory I can recoup this investment in a of couple years. Not bad compared to the 10+ years for the Prius purchase. Now we know gas prices will continue to raise so it would actually pay for itself in less than that amount of time but not needing gas at all is the real solution and it's just cool!
I haven't changed this post because I wanted to keep the real history of the build. Many are reading this post and not understanding things change. Gas was over $5.00 a gallon when I started and to my surprise it did drop and drastically. I originally was just hoping for 45 mile range and on lead acid batteries. This wasn't feasible so I had to change to lithium cells which blew away my original estimate of only $6k.
Recouping the cost was based on the original estimates and gas prices. I haven't done the math but I'm guessing it will take a very long time to pay for itself if ever. It's now just a project that I've thoroughly enjoyed.
