Making Electric Vehicles Pay Off

Posted January 18, 2011 8:44 AM

From Technology Review RSS Feeds:

Commercial fleets are a logical place to introduce battery-powered electric vehicles. After all, fleet vehicles operate with relatively predictable driving patterns, return to a central location overnight, and are managed by sophisticated logistics professionals who can weigh the cars' lower fueling and maintenance costs against their premium purchase price. Last year, managers of large fleets began exploring in earnest what EVs offer, kicking off demonstrations that will come to scale this year.

I would love to see the analysis that the maintenance costs are lower for EV versus ICE vehicles. Some assume they are simply lower because of the reduced moving parts. However, an EV has some very expensive non-moving parts with limited life, namely the batteries. I have driven my '05 Jetta for exactly 100,000 miles over six years and the only maintenance to the drive train (outside of one set of tires) has been the 20 oil changes I've performed. Even if I paid someone to do those oil changes at $25 a whack, that's $500 in maintenance. I have tracked my gasoline costs and I have spent approximately $9,000 in fuel over those 100,000 miles. How much did you say it was for a new battery pack? I figure that I would be on my second replacement set by now. (Three years of daily charge-discharge cycles is about right for a good quality Li-Ion stack). Then add in the higher electric bills.

I'm just a doubting Thomas. Show me the facts.
