Tesla to launch battery swap stations

ecomento.com: Tesla Motors is moving ahead with plans to open battery swapping stations in California, CEO Elon Musk said during a question-and-answer session with owners in the Netherlands.

The session was one of several stops on Musk’s European tour, where he and Tesla CTO J.B. Straubel talked face-to-face with owners. Among the topics Musk discussed was the deployment of battery-swapping stations between Los Angeles and San Francisco.

The trial stations were announced last June when Tesla demonstrated its battery-swapping technology by staging a “race” against a gas pump (guess what won).

Musk said the stations should be online in a few months, and that Tesla will gauge customer interest before considering any expansion of the network.

Each station uses the same machinery employed at the Tesla factory to swap a Model S battery pack in around 90 seconds.

Tesla previously said it would charge owners $60 to $80 a month for the service, though Forbes speculated that owners would be required to pick up their original battery packs at some point.

Battery-swapping will offer Tesla owners a faster alternative to the existing network Supercharger fast-charging stations, which are free to use. At some point, Musk believes owners may choose one over the other.

“As the charging gets better the need for a pack swap gets much less,” Musk said at the Netherlands event, “So it kind of is a bit of a race between the two.”

Customer interest aside, Tesla’s continued interest in battery swapping may depend on the technology’s eligibility for California zero-emission vehicle (ZEV) credits.

As Green Car Reports notes, battery swapping counts as a “fast refueling” technology under the California regulations, which means more potential credits.

The California Air Resources Board – which is in charge of the ZEV rules – considered making battery swapping ineligible, but it hasn’t made a decision so far. If swapping is no longer an option under the rules, it will become significantly less attractive to Tesla.

While the long-term future of battery-swapping remains uncertain, Tesla is preparing a host of updates for the Model S. At the same talk, Musk said the company will launch Version 6.0 of its software in a few weeks.

It may also offer an all-wheel drive version and larger battery-pack options, possibly by next year. Musk also discussed a software-development kit, which would allow third-party developers to create apps for the car. However, there is no firm timeline for this feature either.
