  • Right, the brownout in the electrical system isn’t ideal, but the unintended acceleration seems to be caused by the ADC attempting calibration when the voltage is near-zero. I have to wonder if there’s work that could be done in firmware on the inverter side or on the ADC side to detect and not re-calibrate during those conditions. The PDF specifically calls this out as a potential recall solution.

    It wouldn’t solve the underlying electrical flaw, but could solve the bad signals getting generated and killing people. It’s also possible this flaw causes issues in other systems that haven’t been discovered yet. Much research to be done, I suppose.

    I’d love a new inverter that doesn’t do this, but that seems… unlikely. Let me wish it’s easy to solve :P








  • Likewise! The order of operations is just slightly different:

    Most Cars: Open Car > Pop Hood > Jump/Replace Battery > Drive Car

    Tesla: Pop Hood > Charge/Replace Battery > Drive Car

    If you know this can happen to your car and are prepared for it (the equivalent of being ready to get a jump in a gas car) it’s not a big deal. Of course, many people opt to just contact Tesla roadside and have them handle it, which is completely fine.

    Different cars function differently! EVs from other manufacturers are not universally immune from this either. Meanwhile Mercedes literally tells you not to open the hood on their EVs, much less replace a dead 12v battery.
