Elon Musk Says A 500-Mile EV Could Happen Soon

When asked “How far will a battery-powered car be able to go?,” Musk had this to say:

It will be possible to have a 500-mile range car. In fact we could do it quite soon, but it would increase the price. Over time you could expect to have that kind of range.

For a car that can easily exceed $100,000 even with federal and state tax incentives, jacking the price even higher probably isn’t a priority for Tesla. However, it’s been widely speculated that the Model S is in line for a bigger battery pack, which could go along with a stretched-wheelbase version that’s rumored to be in the works. It’s more than just a bigger battery that gives the Model S more than twice the range of any other electric car; aerodynamics and a unique drive unit make the Model S remarkably efficient despite its heft.

A longer-range Model S takes backseat priority to the soon-to-launch Model X SUV, though, and Tesla’s most important car will be the 200+ mile Model III. Tesla has shown that being able to go 200-miles on a charge is more than enough range to get from one side of America to the other, and a 500-mile battery is unnecessary for 95% of peoples’ daily driving needs (even 50 miles of range is unnecessary for 95% of trips).

Don’t expect Tesla to go hybrid to achieve that kind of driving range either, though a hybrid battery pack might be possible. Rather, Tesla will always be “pure electric” in Musk’s words, fully embracing his notion that every car on the road should be electric. Musk has also pulled back on his autonomous car bluster, saying that he wants customers to enjoy the electric driving experience. That’s a lot less bullish than his earlier claims that by 2017, Tesla will have a “90% autonomous” car. Instead he wants to “alleviate driver workload,” which indicates he’s probably aiming for adaptive cruise control and auto-follow features, rather than a car that “drives” itself.

As for when we’ll see a 500-mile battery, I’d wager it won’t happen until well after the Model III hits the road. For some people, though, this is the ultimate answer to range anxiety.

Tesla Motors is exclusively an electric car maker, with Elon Musk expressing disdain for cars like the Chevy Volt and BMW i3, which pack gas-powered range-extenders. But Tesla may be working on a different kind of hybrid; a hybrid battery pack that could extend the range of cars like the Tesla Model S by up to 40%, allowing for 400 miles of driving between charges.

A report by Global Equities Research shows that Tesla recently filed patents 20130187591 and 20130181511, which describe a combination lithium-ion and metal-air battery pack. This hybrid battery pack would primarily use the lithium-ion side, only drawing power from the metal-air battery pack on extended journeys. Metal-air batteries, which use oxygen as an electrode, have a shorter lifetime when exposed to regular charging, but use more common elements like zinc or aluminum that drastically reduce battery costs.

Drivers would use the lithium-ion battery for daily use, and would either select the secondary battery, or have it automatically switch over on extended trips. A hybrid battery of this type could offer Tesla customers greater driving ranges, while not drastically increasing costs. There’s also mention of a mode whereby the metal-air battery would charge the lithium-ion battery, which powers the car’s systems. 95% of driving consist of short jaunts no more than 90 miles per day, but the option of going 400 or more miles on a single charge could open up the world of electric vehicles to a much wider audience.

For now though, Tesla will still rely on Panasonic for batteries, as they have a four-year, 80,000 unit contract with the Japanese tech giant. But going forward from there, who’s to say Tesla doesn’t deploy ground-breaking battery technology of its own? This could be a peek at the future, folks.
