If there is one impediment in the fast adoption of electric vehicles is the battery technology which still delivers a fairly limited driving range in electric vehicles. BMW has recently updated its battery pack in the i3 to deliver 50 percent more range, for a total of 120 miles of pure electric drive. And while that’s enough for most daily commuters, the mainstream customer is craving for longer EV ranges.

According to Autocar, BMW is aiming to fix this issue with a breakthrough in battery technology in 2026, by which time it plans to have solid-state batteries ready for production in its models.

The batteries will use lithium ion technology but swap liquid electrolytes for solid ones, with initial targets being for a 15-20 percent increase in capacity.

A second, but equally important benefit of the new battery technology is a reduction in weight and in the amount of safety protection needed due to the reduced fire risk.

The report also says that the the batteries are currently in development but 10 years away from production, with long-term durability testing cited as a key reason for the delay.

BMW is currently building their battery packs in house, with cells being provided by various companies.

    Wow, I was under the impression that battery technology was on the verge of much greater things, much sooner. That’s if you believe everything you read. ;)

    This waiting for a battery break though talk from a car manufacturer tends to only come from those who are looking for an excuse to stall. Toyota did the same thing until recently, they used to say batteries weren’t good enough yet. But claiming that they’ve made a breakthrough, they have started work on their own electric cars.

    This is crazy! Or merely funny. Battery technology is moving fast and not predictable, and BMW is projecting a specific improved battery tech ten years from now? (and only 10-15% improvement?) Sounds like a new rationalization for perpetual procrastination. And if they want to do something to reduce fire risk, they will stop building inferno-prone fossil-fueled cars, or at the very least, start putting self-sealing bladders in their fuel tanks.

      Where can I get one of those self-sealing bladders?

        Buy a race car — they are required to have them as a safety feature. Adds to cost so manufacturers don’t use them for street cars. Most everyone seems to accept burning ICE cars, trucks, and buses. You see photos of vehicles ablaze every day and nobody raises an eyebrow, and yet when you see the rare electric car burning after being obliterated in a high speed crash, it’s headlines. Sigh.

    …and the weight of that battery pack?!

    The point is, BMW is about safety and Chevy, Tesla are not. Unfortunately no customer cares about that because no one sees it. The battery pack is totally different in a BMW than in a Tesla or Chevy, its much safer – maybe too safe because of less range. We will see what is better on long term when the first Teslas and Bolts are burning…

    • Chris Llana says:

      If BMW already has a totally safe battery pack, why don’t they continue to introduce new electric models? Why wait another ten years?

      • Max says:

        Ehm, u know that there will be an X3 and Mini in the next 2 years?
        What do u think – how long does it take to develop such a car? 1 year?
        People with no clue about development of a car, shouldnt complain about anything…

    2026 is so far into the future,it may as well be 2096.

    So now BMW wants to adapt battery technology in their cars. If it is effiecient, they every one will love it. But they should think about the speed of the car and the cost too.
