Tesla Preparing for Battery Swapping Stations?

EV maker files application for patent.

by on Sep.18, 2017

Tesla filed a patent application for a battery swapping device.

Tesla appears to be following up on a plan it revealed a few years back to swap out dead batteries for fully charged ones for owners of vehicles who don’t have access to a supercharger.

The California-based EV maker filed a patent application for a portable battery changer design that would allow technicians to make the swap in as little as 15 minutes. A quick scan of the diagram in the application shows many similarities to the model it demonstrated in 2013.

However, the version in the application appears to be smaller and portable, according to This would allow them to be set up in areas that do not have superchargers. The company showed off its ability to swap the batteries in June 2013. (more…)

New Nissan Program Could Let Leaf Owners Upgrade Batteries

Maker will launch battery replacement program in 2014.

by on Jun.21, 2013

Nissan has been working to reassure owners about the batteries in its Leaf EV.

Nissan plans to launch a new battery replacement program in 2014 that could let owners of the Leaf electric-vehicle benefit from anticipated improvements in lithium-technology that could result in smaller, lighter, longer-range – and less expensive – batteries over the coming year.

While details of the program have yet to be finalized, the maker would permit U.S. Leaf customers to swap out their original batteries for new ones, whether because the old packs were losing power as they aged or because improved batteries were to become available.

“Technology is evolving and battery prices are projected to decline as EVs become increasingly mainstream,” said Erik Gottfried, Nissan’s director of Electric Vehicle Sales and Marketing. “Therefore, this new battery program today affords more flexibility for the future so that customers can both upgrade to the latest available technology for their LEAF and enjoy more predictable vehicle operating costs.”


Tesla Demo’s 90-Second Model S Battery Swap

Faster than filling a gas tank, declares CEO Musk.

by on Jun.21, 2013

Tesla demonstates the speed of its battery swap system compared to the time it takes to fill up at "the fastest gas station in LA."

Beyond the high cost of electric-vehicle technology, perhaps the biggest turn-off for consumers has been the lengthy time needed to recharge products like the Model S.  Or so goes conventional wisdom.

But the maker has set out to show that recharging the sedan doesn’t have to be an obstacle – first by announcing plans for a nationwide, high-speed “Supercharger” network and, now, by demonstrating the ability to swap out a depleted battery for a fresh one faster than you can fill up a gas tank.

The Last Word!

After tweeting plans to prove that possibility, Tesla CEO Elon Musk invited journalists and several hundred Model S owners to the factory to demonstrate the new battery-swap strategy. On a video screen overhead, a Tesla employee was shown filling up a car’s gas tank at what the South African-born executive described as “the fastest gas station in L.A.”  On stage, a robotic machine automatically removed a Model S battery and replaced it with a fully charged one.


Tesla May Offer Battery-Swap Option for Model S

CEO Musk hints of recharge option faster than filling a gas tank.

Barely a month after announcing plans to set up a high-speed network of “Supercharger” stations across the U.S. and Canada, Tesla CEO Elon Musk is hinting the start-up electric vehicle maker might also adopt a battery swap system that could allow owners of the new Model S sedan to have a freshly charged battery pack “faster than you could fill a gas tank.”

Tesla has been exploring the idea of swapping batteries for a number of years.  The approach is, at least conceptually, quite simple. When one battery pack runs down, simply switch it out for another, much like changing batteries in a flashlight. But, in practice, it’s a lot more difficult than it might seem.

Stay Wired!

“Live pack swap demo on Thurs night. Seeing is believing,” tweeted Tesla Musk this week. The South African-born executive is fond of using Twitter to alert friends, fans and the media of the company’s plans, including news of the expanded Supercharger network.


Tesla Announces No-Fault Battery Warranty; “Valet” Loaner Program

CEO Musk hints battery upgrade program “a good likelihood.”

Tesla Motors CEO Elon Musk has announced a series of steps designed to give Model S electric vehicle owners “complete peace of mind” about the durability of their batteries and the cost and convenience of getting the Model S sedan serviced.

Meanwhile, Musk told that there is a “good likelihood” that the California-based automaker will eventually offer owners the ability to upgrade their current lithium-ion battery packs as more advanced battery technology becomes available.

The Last Word!

“We’re focused on creating the world’s best factory service experience to match what many have called the world’s best car,” Musk said during a media conference call on Friday.

The Tesla founder outlined a variety steps that will be taken, including a new valet service program in which customers can have their Model S picked up by the dealer, rather than having to take it to the shop.  The valet will leave the owner with a Tesla Model S 85, the most expensive and longest-range version of the battery-electric vehicle, as a loaner.
