    Hate to spoil the anti cybertruck band wagon here, but apparently the owner discovered that they were doing something wrong. I think they seated the charger incorrectly, which allowed it to charge for a bit, but then the safety mechanism from the truck turns off the charging. These trucks and other electric vehicles can charge at this temperature range, but they will have reduced range.

    Elon is still a Nazi, and these trucks look horrendous.

        i mean standard outlets have live neutral and ground, neutral and ground are ultimately both connected to the true ground in the earth, but neutral is the ground the current optimally flows through, whereas ground is just used for safety to prevent metal casings of devices from silently being connected to live or whatever. dont know how much of that applies to ev chargers but probably not too far off.

          Yeah at some point they would combine at least, I think. I’m not certain about US American standards.

          Here in Switzerland, and in Germany too, we use the TN-C-S system (terre neutre combiné séparé) at least for any recent buildings.

          That would usually mean that you mustn’t combine ground and neutral within your house (behind your breaker box). Otherwise RCCB / GFCI breakers can’t work either obviously.

          I could see car chargers being wired up a bit specially, I have no idea about them to be honest, but surely they want to be able to check for ground faults as well.

        I don’t think that’s what this is saying. It seems to be saying it just wasn’t plugged in all the way.

            Oh damn. My eyes just glazed over that part because the idea of someone who clearly doesn’t know what they’re doing taking apart a charger for a car is so insane.

          Between this and the burning 4090 fiasco from a couple of years ago, it seems to me that people who buy expensive things struggle to plug them in all the way for some reason.

        Ooo I didn’t understand that before, I thought it was not plugged in right. If I’m understanding you correctly, his fix could have been very dangerous

      Also many of these chargers are installed on off-peak meters so that you can get a few cents per kwh off. In the winter in cold areas like Minnesota peak shaving happens in the middle of the night because many homes are on electric heat.

      So if it is cold enough for the electric company to be peak shaving, you may lose several hours of charging through the night

          You can purchase electricity at a variable cost. Low demand times have low prices; inverse for both as well. One can automatically disable a charger during high demand times and enable it during low demand times to save money. For a level 2 charger that is used often, it isn’t a bad plan.

          However, if there is really high electric demand when you want to charge your car, and you don’t know the above setup is happening, it can be confusing when your car stops charging.

            In areas that don’t have variable rates like where I am at it is just a straight discount per kwh no matter when you use the power.

            However the power company puts in a separate meter which has this lower electric rate for the things you want on the off-peak service (the charger in this case). That meter has a unit that they can remote control to cut the power whenever they choose.

            So when the power company sees that their grid is nearing capacity they start shutting off customers off-peak meters for a couple of hours at a time. This usually happens in the middle of the night in winter when it is really cold, or the mid to late afternoon in the summer when it is really hot.

            Traditionally this was for homes with electric heat. The power company would only allow this when you had a second heat source like a furnace. The point being that they are effectively shifting from electric heat to some sort of fossil fuel. A lot of homes from before the 70s/80s had multiple heat sources because fuel shortages forced a lot of homeowners to add electric heat, but they still had oil furnaces they could fall back to.

    I’m gonna take a slightly different approach on this one.

    If you live in an area which gets to sub zero temperatures and didn’t consider the impact that has on batteries before buying electric, this one’s on you.

    The Tesla Cybertruck is not the only EV that struggles to charge in very cold weather, but it is the ugliest and most facist EV around.

    When it is below freezing, you have to hardwire your mains power straight to the cybertruck’s battery. Everybody knows this.

      I heard pouring petrol down the back of it and setting it alight makes it warmer, thus allowing the battery to hold the charge more effectively

        Level 2 chargers only supply 240v AC.

        They have a lot of protection circuitry to make handling them in wet / rain safe but everything else is up to the EV to handle.

    It is an incredibly inefficient EV and they compensated for it by putting a huge battery in it. It will not charge quickly.

    I want to laugh in this guy’s face in person, but Minnesota is kind of far away. Can we set up a videoconference? That would be the next best thing.
