  •  Solution - You keep the battery. (14+ / 0-)

    When you sell the car, you just keep the battery and use it in your next car.

    That solves all the problems described here:

    The economics of the market in this situation are fairly complex. When the car is a junker, can you remove the battery pack and sell it used? Presumably. But wouldn't the buyer want to know how many cycles the pack had on it, just like the buyer of a used car wants to know the mileage? How would the buyer know if the battery pack had already powered through the lifetimes of two cars, or four, or six? And how could you actually track that number that in a non-corruptible way? Beats me.

    But I guess that's what the comments are for.

    Please don't call yourself a "DFH." It's not helpful.

    •  Yep - Batteries Sold Separately (18+ / 0-)

      It really doesn't sound like much of problem, as the question of the battery would only be an issue if the car is junked. But if the battery was the most valuable part of the car and people wanted a battery that they knew exactly how much use it had had then the battery and car would be considered separate items and people would keep their battery until they needed a new one.

      •  modular battery packs... (8+ / 0-)

        the aftermarket would be huge.

        •  I only need a short range (0+ / 0-)

          don't need to pay for more battery than I can use...lease batteries, or options as to capacity...build in the capacity in the car, leave the batteries out, the car itself would be less than 10k probably, much less.

          I guess we can look for Chinese batteries made from maple sugar any day now...and providing the options and low price consumers will demand.

          Seriously Keith, making these not for consumer cars is not gonna last if they are as cheap as lead acid...somethings not adding up here, you can convert your gas powered car, for popular models there are motor/battery/controller kits available, that's recycling, not crushing useful car hulks when basically bolt up EV options exist.

          Making these with LIthium batteries gets the cost near new EV prices, lots of converters still use lead waiting for the price to go down, as this will.

          There was an experimental preproduction battery called the Firefly iirc that tried niche marketing like this at first, with the same rationale about consume...no wait ...'consumer' batteries.

          Firefly was spun out of construction and mining equipment maker Caterpillar in 2003 to develop lead-acid battery technology for commercial and military use that the company says are lighter, cheaper, more rugged and more powerful than traditional lead acid batteries.

          Firefly filed Chapter 7 bankruptcy

          At the end of the day manufacturing battery technology requires a lot of capital. And in particular significant capital to move a startup through the so-called valley of death — the gap between proving the technology and scaling. Firefly Energy, like many others, just couldn’t make it through that expensive phase.

      Some batteries already have this capability embedded in them.  I know for example how many cycles my liON laptop battery has endured and what its current power capabilities are by consulting an onscreen app.
