He was happy to let in on his project and agreed to answer a few

Q: What got you interested in electric

A: I’ve been concerned for some time about the impacts of single-passenger driving Between peak oil, warming, air pollution (both and ozone), and water pollution gas stations and refining) I am convinced we need a better way to get around My own personal commute is less 15 miles round-trip, and I knew this is similar to many – the typical daily driving is less than 30 miles.

Q: Do you have a technical education, or in a technical profession?

A: Yes to both. worked for 25 years in the computer mostly at the lowest levels of (drivers, operating systems, This has given me familiarity many engineering concepts, as designing proper experiments, and analyzing data, and how to find and apply it to a problem.

A: My in electric vehicles initially me want to buy one. But there not really any good options for vehicles when I was searching in After doing some I found out that the Porsche 914 was a ideal conversion “donor”. It has and rear compartments, is light and has many original and after-market available, and has a relatively simple system.

So, in 2005, I found a suitable 914 100 miles away that I specifically to become an electric

I did not fully the magnitude of what I was getting – the “kit” turned out to be fairly with inadequate instructions. I that company has since improved their kit, on feedback from me and others who converting at the time.

As I was building the I found several communities of who were able to help me sources for various components. communities are still around, and are helpful (two big ones are at and evdl.org ). You can get all sorts of recommendations on providers and design considerations fellow EV conversion enthusiasts.

Q: What was the cost of the electric

A: I went “high-end” for the time – AC and controller, and 144V battery size. This translated to $14,000 in cost for the elctric People could do a simpler for probably around $8,000

Q: How long did it take you to plan the gas to conversion process?

A: Since I a kit, the “planning” time was than you might otherwise The actual conversion process about 3 months of part-time

I’ve documented of those links at my Volt914 .

Q: How long do you expect the batteries to

A: I replaced the original batteries 2 years. Not because they worn out, but because I had that flooded lead-acid were not a good technology. I replaced them with lead-acid batteries, at a higher voltage. I expect the new batteries to 3-5 years with the kind of / charge cycle that I (I very rarely discharge 50%).

Q: Your video shows you in cold weather. How much temperature affect the battery

A: Cold weather can definitely range. At freezing, range is half what it is at “room And range goes down more rapidly below With my battery upgrade, I am adding battery warmers will both extend my range as well as improve the of the batteries.

Q: Are you going to convert any vehicles?

A: As I said, I have converted a Jeep Cherokee. I am an electric scooter project. And I am likely to do an electric-assist 3-wheel (human-powered tricycle). I seem to caught “the bug.”
