Battery Swapping is Dead! Long Live Battery Swapping!

IEEE's Bill Sweet consider's Tesla's recent 90-second battery exchange and its implications, as well as the impact of states trying to block sale of their luxury electric cars.

Less than a month after Better Place's bankruptcy filing—which seemed to be the kiss of death for the vision of an automotive future in which owners of electric cars would switch out their batteries rather than recharge them—high-flying Tesla Motors has revived the idea. In a press event Thursday evening, Tesla's somewhat oddly attired Elon Musk showed how the the company's Tesla S luxury sedan could be recharged in just 90 seconds, hovering over a robotic setup in which the battery would be automatically located, unbolted, removed, and replaced. (In the above photo from the presentation, a person is seen filling up a car with regular gasoline (left), while the Tesla (right) is having its battery switched out in less time.)

Is battery swapping really dead? Tell us what you think. Take this month's ePoll on EV World's home page.

In the video, Musk wears a highly styled tuxedo jacket over a black T-shirt, a nod perhaps to the class of consumers who can actually afford to buy the Tesla S. Which brings us straight to the completely obvious question of why Tesla, which appeals to a tiny, elite class of consumers, would succeed where Better Place, backed by a global mass-market car maker, failed.

Perhaps part of the answer, if there is a good answer, is to be found in comments made in our earlier post concerning the Better Place bankruptcy. Regarding Better Place's support from Renault and its famous CEO Carlos Ghosn, one reader observed that Renault in fact "had already all but abandoned Better Place to their fate, as can be seen by the non-inclusion of their technology on the [company's all-electric] ZOE [model]." As for Better Place's trials in what I had called "tech-savvy" Israel and Denmark, another caustic reader suggested that sure, they might have succeeded in those tiny places, but that "the number of batteries and stations would go up by the power of 2 in countries or markets with larger areas" because of all the extra batteries and stations needed to service a single car.


Tesla has now begun deliveries of its Model S all-electric sedan.

While the Model S will be half the price of the Roadster, it is still more expensive than the Nissan LEAF which has sold only around 30,000 units.
