Tesla, the Silicon Valley-based company which has made its name on designing, manufacturing, and selling innovative and luxurious electric car models, added another major innovation to the alternative energy game on Thursday. According to a report published by HighlightPress.com on Friday morning, the company has designed a new procedure that could replace long battery charge times with a quick and easy power-cell-swap program

Presenting their new technology to an audience of Tesla vehicle owners, the company showed how a mechanic could rapidly replace a dead battery with a fully-charged one. The procedure, which was demonstrated using Tesla’s flagship Model S sedan, took just 90 seconds, a brief period of time that not outstrips the convenience of electric car charge times, but of regular car fueling stops as well.

Of course, Tesla’s new service faces the same problem that electric cars have faced all along: charging stations are hard to find–far more difficult than regular gas stations–and locating a Tesla-approved mechanic to change your car batteries would be even more difficult.

Elon Musk, Tesla’s CEO, addressed that problem right away, promising audience members that the new battery swapping-program would begin to spread throughout California by the end of the year. The company plans to expand their offerings beyond the state later, but in the near future at least, the program will only exist on the west coast.

The new service works almost like a regular body shop check-up, or perhaps even like an oil change. Drivers park over a whole in the ground and a mechanic waiting beneath their car then executes the battery change. Tesla’s prototype presentation was sleek and well-rehearsed, and the company’s decision to simultaneously show a video of a Tesla employee filling a car with gas was a nice touch to show that, yes, electric cars can be more convenient than gas-powered models. That the video was supposedly filmed at “the fastest filling station in Los Angeles,” making the gimmick  that much more effective.

As the stopwatch clocked at 93 seconds, the first Model S drove away and another took its place. By the time the mechanic had switched the batteries for both Tesla vehicles, the regular car was still filling its tank at the Los Angeles gas station, a stop that took around four minutes. In other words, Tesla drivers could save a lot of time if this service was implemented everywhere.

Musk told audience members that the service would cost roughly the same as 15 gallons of Regular gasoline.
