The Quest For an EV Fast-Charge Standard

Posted by Soulskill on from the everyone's-plugging-their-own-plug dept.

An anonymous reader writes "This article explores one of the stumbling blocks currently facing EV adoption: 'Sure, there are already public charging stations in service, and new ones are coming online daily. But those typically take several hours to fully replenish a battery. As a result, the ability for quick battery boosts — using a compatible direct current fast charger, the Leaf can refill to 80 percent capacity in 30 minutes — could potentially become an important point of differentiation among electric models. But the availability of fast charging points has in part been held up by the lack of an agreement among automakers on a universal method for fast charging — or even on a single electrical connector.'"

    I think some of the battery arrays should be able to pulled out of the car and swapped in with a charged battery array. This process could happen in under a minute.

      I don't think they would sell it like that. You probably would purchase a "licence" for a battery, basically, the right to a working one for the pool, pay for the charged swapover, and have failure replacements calculated into the swapover expense. The concept of "new" and "old" battery wouldn't really come into it.

      I might be a little picky about swapping my brand new cells with an unknown station's current cell stock.

      Treat them like gas canisters then. The canister remains the property of the company and all you do it buy the contents. The company is responsible for ensuring the canister is functional, safe etc. If the battery develops a fault - you can simply swap it free of charge for a new one. Obviously you are paying for this in part of the fee when you pick up a fresh battery, but it saves having to horde your own precious batteries.
      To be honest I am surprised that the industry didn't do this from the get go since such schemes (as mentioned above) already exist all over the globe for many things. All there needs to be are a few agreed standards on size etc. Again, just like gas canisters really.
      If one company makes a better battery that can fit into the same volume, then they can compete. heck, such standardisation could stimulate a new battery market.

      The same way that is stopped now with every other item you purchase. By complaining to the store and authorities, and by suing them if necessary. At the very least, stop going there and tell everyone you can.

      Fraud is a crime.

  2. Just like laptops! by OITLinebacker · · Score: 1, Insightful

    You can't even get a single laptop maker to standardize within the models they currently offer. I find it difficult to believe that an industry that can't even standardize on the tires to agree on their connectors. It's a wonder they even all agreed to use Gasoline (and even then you have models that "prefer" specific octane).

    Battery technology certainly is evolving; but the "put power in" part is a fairly reasonable place to put a nice abstracted interface.
