    I so bad want this to work. I hate computers in cars (beyond the ecu for efi and abs, that is all a car needs)

    Sucks that its bezos funded but hey. Take what we can.

      Battery management requires a lot of computer logic. The simple act of plugging in an EV to a charger involves a complex handshake for negotiating the amount of power to deliver, which the control unit figures out by reading the sensors in each battery cell, and routes the electric power to the appropriate cells. Same thing for discharging the battery to power the vehicle, and recharging the battery from regenerative braking while driving.

      No matter how you slice it, an EV requires much more computing functionality under the hood than an ICE vehicle, just for the basic powertrain management.

      I’m with you on user interfaces, though.

        That’s not a privacy issue.

        The computers are issues when they include sensors, logging, storage, and uploading your data to others.

        I’m not totally sure. Even an ICe car now is insane for all the modules. Sure I can see battery management in an ev being robust but I’m sure it could still be pretty simple. Look at just injectors and cam sensors in an ice vehicle and the engine harness, its insane. Not to mention the entertainment bullshit that needs all its own modules.

          Yeah, modern cars are basically engineering marvels. Even when a lot of this stuff was mechanically controlled it really was something amazing to see just how precisely every little moving part did its perfectly timed function, thousands of times per minute across all 4 (or 6 or 8 or more) cylinders, pushing power through the transmission and differential and wheels.

          That said, I still think that trying to understand the physical ground truth of the electrochemical energy stored in each of the 5000+ cells by reading sensor data on voltage, current, impedance, temperature, and a log of how many times each cell has been charged or discharged, does require greater electronic complexity and more sophisticated programs to manage, than an ICE control unit does.

            It is pretty amazing!

            Sure I can see that. Still an ev could be very simple besides the charging computer. No other techs really needed.

      Don’t forget about the tire pressure sensors hidden inside the tires that operate wirelessly and have been shown to be able to track the vehicle. Hopefully this van doesn’t have those, but I think it’s a federal law to use them?

        Yep thanks to ford (rollover lawsuit). Ford also patented vehicle tracking and cameras inside required to start the vehicle. . Probably one of the worst vehicle companies.

        Jokes on them my tire sensor batteries all died heh

        Oh, darn. Mine broke and I replaced them with valve stems. I’ll have to rectify that soon, I guess.
