  • government regulation to force companies to begin using a modular system

    Yeah, that’s fair. But the issue is also similar to cell phones.

    Each battery is unique because it needs to fit the unique layout of the vehicle. Not to mention the battery tech is moving so fast, that the chemistry of the battery itself is changing every few years.

    I suspect China’s approach to a vehicle where you hot-swap the batteries instead of charging will be the way it goes. Someone will do it, it will be most $$$ efficient and therefore profitable, and then it will force them all to adopt the same approach.


  • The replacing the battery is simply a supply issue.

    There is such a demand and so little supply, that if you want to buy just a battery (and not the entire car) you are out of luck. They’ll put that battery in a new car and sell it before selling it to you as a replacement.

    But that’s short term. There are a huge number of battery plants already breaking ground and coming online.

    In 2 years or so, the price to replace the battery will be a HELL of a lot lower, and the issue you linked above will be long gone.



  • Stuff with motors are, like air con and refrigerators. Those are better left on AC.

    No. Trend is they are all showing up with frequency drives. Of which those inverters are rectifying to DC before making their own AC.
    Efficiency gains are massive of a frequency drive , hence why they are doing it.
    Would be even better if they could drop the first rectifying circuit and just use the inverter portion only.

    You lose very little by rectifying AC

    You lose a lot actually in all the small cheap rectifiers that are in every device in the house.

    Where a single purpose designed FET rectifier that is built for efficiency at the breaker would be drastically better.
