free may be a good way to help sell cars, but if and when a car sells itself, people won't mind paying for convenience. by the recharging may be much shorter though. i just thought battery swap stations like the guy in israel wanted, would help break down the barrier.
Batteries are one of the most expensive things, if not the most, on a BEV. For battery swapping to work, the station would need to keep several of those expensive things on hand; plugged in to minders to keep them topped off. With a low level of customers, it is a large capital investment. I think enough people have gotten bad batteries out of the box, or had replace the lap top one within a couple years, or had a starter battery fail them, that they would be hesitant to take a traction battery for a BEV that hasn't been in their possession since new. You just got a brand new BEV, would you want to exchange that new battery for one that might have several thousands of more miles on it, just to avoid waiting for a charge? Enough people were hesitant enough that the Israel company went under.
But now the conversation has made a full circle. The "why not?" was asked and answered by Tesla...The owners were uninterested. Period. Whether they should be interested or incentivized is an extremely different question. This was not a survey, but a real offer by Tesla and was answered quite clearly...No, they would rather make use of the (free) supercharger.
I don't think the potential of battery swapping got Tesla any new sales. While mismanagement may have done Better Place in, the company only sold a thousand cars in Israel. Tax credits, rebates, and HOV access seem to have done a better job of getting people into plug ins. The battery lease route for reducing the initial price of the cars, hasn't been a big success at moving people to the cars either. Better Place - Wikipedia, the free encyclopedia
