While Tesla owners — and owners of all EVs, for that matter — may be waiting a couple of years before titanium oxide anodes bring battery charging levels down to the 3- to 5-minute fueling times found at a given gas station, CEO Elon Musk has another option for them to consider: Battery-pack swapping.

SlashGear reports the first swapping station will come online within the next few months, offering S and X owners the option of allowing robots to swap a drained pack for a fully charged unit from underneath the car within 90 seconds. Not only is this method faster than refueling at the local ARCO, but it blows away the Supercharger’s 30-minute charging time, as well.

The pack swap would also enable owners to retrieve their original packs later on, or, should retrieval become inconvenient, pay the difference for the new pack. Critics note this could lead to supply problems, where some stations have batteries waiting for their owners to return, while others run short of new packs.

The first station will open somewhere between Los Angeles and San Francisco, though further details were scant.
