GM to challenge Tesla’s electric battery dominance

Climate Progress

General Motors plans to challenge Tesla’s share of the electric vehicle innovation marketplace by doing two things: making a better battery, and putting it in a long-range electric car that’s affordable.

GM announced this week that it’s developing a car that can go 200 miles on a single charge — the same distance that Tesla’s Model S can. But the GM version will cost about $30,000, less than half the $71,000 sticker price of the Model S.

The company is also aiming to do an overhaul of the electric car battery. As Quartz explains, Tesla’s Model S uses Panasonic batteries made of nickel, cobalt and aluminum. GM wants to use a lithium-ion battery made of nickel, cobalt and manganese — a chemical mix that scientists think could create a cheaper and more powerful lithium-ion battery, but that right now has some flaws that GM hopes can be fixed.

Right now, GM sells two battery-powered cars: the Chevy Volt, a plug-in hybrid which costs $35,000 and can go 38 miles on a charge before its gas-powered generator takes over, and the Chevy Spark, an all-electric car that can go 82 miles on a charge and costs $26,685 (both costs are before the $7,500 tax credit that electric car buyers are eligible for in the U.S.). GM is also focusing on making its current cars cheaper — the company has said the next generation of the Volt will cost $7,000 to $10,000 less than the current version.

Tom Libby, lead North American analyst for the Polk automotive research firm, told USA Today that an affordable, all-electric car that goes 200 miles on a single charge would go a long way in enticing more Americans to buy electric cars. Cost and range anxiety are two of the top reasons Americans don’t buy electric cars — today, all-electric cars make up only 0.3 percent of U.S. sales. So far, Tesla’s Model S has helped eliminate range anxiety, but its luxury pricing is still prohibitive.

“Their pricing is up there for a real unique customer,” Doug Parks, Vice President of GM’s Global Product Development, said of Tesla. “The real trick will be who can do a 200-mile car for more of the price range I’m talking about. We’re all in races to do that.”

For its part, Tesla has also discussed plans to release an affordable, long-range model within the next few years. And GM and Tesla aren’t the only car companies attempting to revolutionize the electric and hybrid market. In July, BMW announced its first electric vehicle, the $41,350 BMW i3, which can go 80 to 100 miles on a single charge and can be bundled with access to a BMW sport utility vehicle for several weeks out of the year. That way, a customer can buy the electric i3 for day-to-day driving, and get access to the conventional SUV for family vacations and road trips. It also comes with a smart phone app which displays information about the car’s charge level, battery condition and location.

    Most car trips are well below 200 miles. This means that the battery cost per km for those last 100 km of travel are going to be very expensive. Plug in hybrids are one practical solution but, once again, the cost per km for those few kms that depend on the motor are going to be quite high.

    However, aluminium air batteries make pure EV look more practical. (See:

    http://inhabitat.com/phinergys-recyclable-aluminum-air-battery-could-power-evs-for-thousands-of-miles/ )

    These batteries are not rechargeable but have claimed ranges in excess of 1600 km. The plan would be to use the rechargeable batteries for normal urban travel with the aluminium battery being used as back-up to protect against range anxiety or to cover an urgent call to rush down to Byron Bay to visit your sick friend.

    They may also be cheaper than using a hire car for an occasional trip to Sydney but probably not OK if you drove outside your battery range every weekend.

      Tesla has just been awarded a patent for a similar setup, but using a rechargeable zinc/air battery for the longer range stuff and a controller that hybridises the motor power feed by switching between that and the lithium ion battery which has much higher current capacity than the zinc/air.

        juxx0r: To be long range practical in Aus you need a back-up that will do something over 1000 km. Aluminium air gives a better energy storage than zinc.
        Is the Tesla zinc air rechargeable?

          I dunno about you, but i generally stop about every three hours when i’m doing long distance, so i think 1000 wouldn’t be necessary for my needs, but then the charging infrastructure would need to be in place. However zinc air has low current capabilities for both discharge and recharge, so i dont know how that’d work, would need to be a compromise like everything else.

          Yes the zinc/air is rechargeable, but there was another article i read which called it a primary battery, but i think that was just journalistic confusion.

          Lithium batteries are getting better at 10-15% a year, so that’s going to help long term anyway, then there’s the breakthrough technologies like lithium sulphur that might surprise too.
