  • Its a fully electric drivetrain with a gas generator. When the battery runs low you can recharge it (even while driving) using the generator.

    So you don’t have the complexity of a combined hybrid drivetrain, but instead a normal BEV one plus a power generator, both of which are very well understood problems.

    Another benefit is that the generator can always run at its most efficient rpm/power point and is decoupled from the speed of the wheels.

    Interestingly Wankel engines have been making a bit of a comeback for this purpose since they can be built more compactly for the same output power.

    A drawback compared to hybrid drivetrains is that both components need to be built for “full” load, whilst a hybrid drivetrain can combine powers to reach maximum performance, meaning each of the motors only has to carry half (or part) of the total load.



  • Just out of curiosity I don’t see how 4 sticks die together at the exact same time unless the PSU is/has fucked up hard.

    I’d argue that the likelihood of 4 sticks failing together is much lower than the MOBO or CPU or PSU failing in a way that makes RAM inaccessible.

    Typically you’d see one stick failing at which point you could take it out and run with the other 3 (or 2 depending on configuration).

    Anyway if you ever intend to return its probably best to keep the rest of the components because who knows which of those will be up next for a shortage/crisis.






  • Like you already hinted at batteries are DC systems and can only be charged using DC. Many EVs have at least a small AC to DC converter on board. When you plug it into an AC source the charging speed is limited by the size of that converter.

    DC charging stations bring their own converters which are oftentimes much more powerful and therefore heavier than what your car carries along.

    Whether you use an external 19kW converter or your cars internal converter doesn’t make a difference. In both cases the cars charging circuitry will monitor for dangerous situations such as overheating and throttle the charger down if need be.

    The important question is how large your cars converter actually is. Sure the L2 charger provides 19kW AC but can your car’s converter actually use all of that?

    If it can only do 10-15-ish kW then it’ll charge slower and therefore won’t tax the battery as much as a DC charger with 19kW would.

    I don’t know what car this is and how PHEVs play into this but existing BEVs have been charging with much higher speeds for more than 100,000 miles and generally don’t end up with broken batteries.

    Depends a lot on the make and model of course, as I’m sure there are some horrible examples out there. But the public fast chargers wouldn’t be under such demand if it was that damaging to the cars.


  • The post text doesn’t seem to get displayed on some clients (Voyager) so I’ll attach it here as well:

    asciinema (aka asciinema CLI or asciinema recorder) is a command-line tool for recording and live streaming terminal sessions.

    This is a complete rewrite of asciinema in Rust, upgrading the recording file format, introducing terminal live streaming, and bringing numerous improvements across the board.
