 @LilahTovMoon That's why it's not gonna make it here in Germany. We're running on 230V. @cgudrian @LilahTovMoon don't mix up static electricity / direct current (like in the video, 120V) with alternating current (230V in Germany and many other countries). @das_menschy @cgudrian @LilahTovMoon not sure what you mean, the video appears to show 120Vac on the exposed metal of the vehicle. @Wifiwits @cgudrian @LilahTovMoon Ok, so I was wrong. I thought it's static electricity. My fault.  @das_menschy  @momo @das_menschy @Wifiwits @cgudrian @LilahTovMoon "No idea if we got the license or not. The inspector ran screaming towards the horizon and disappeared there. 🤷♂️" ;-)  @Habrok42 @momo @das_menschy @Wifiwits @cgudrian @LilahTovMoon It's most likely the charger is miswired- they are using AC charging and line and neutral are reversed. Neutral should be at ground potential, so if there's LN reversed, the chassis of the device (appliance, Cyberturkey, wotever) will have line voltage present. However, there's no excuse for the vehicle not detecting this wiring fault and warning the user and disconnecting the AC charger- that part is on Tesla @weezmgk @Habrok42 @momo @das_menschy @Wifiwits @cgudrian @LilahTovMoon I agree it's most easily explained by a charger issue, but how should the car detect that, given that it's not grounded itself? I think the charger would have to have not only L and N reversed, but also PE connected to L, plus probably no RCD. @cm N & earth should be at at the same potential (or mV close to it). If it isn't, the car should disconnect and go into a fault mode and put an alarm notice somewhere (dash cluster? Display screen?) This is what they pay the EEs big bucks for. @Habrok42 @momo @das_menschy @Wifiwits @cgudrian @LilahTovMoon @weezmgk @Habrok42 @momo @das_menschy @Wifiwits @cgudrian @LilahTovMoon What the car sees on L, N and PE might not be the same as the outside world does, assuming sufficiently malicious wiring in the EVSE. And without a stake in the ground you can't really determine whether the wire labeled "PE" is at that potential. @cm There's an earth reference in the charge connector, which should be sufficient to determine if L&N are correct or reversed. Most device design simply trusts that the sparky who wired the residence didn't cock it up. But it is possible to detect such a fault and protect the user from it. At the price of an EV, I would rather expect that feature would be there, it's not a toaster. @Habrok42 @momo @das_menschy @Wifiwits @cgudrian @LilahTovMoon  @das_menschy @Wifiwits @cgudrian @LilahTovMoon This isn't. @JeffGrigg most drivers of any type of car experience static shocks. Caused by rubbing clothing fabrics on car upholstery. If the driver wears rubber soled shoes, there will be a charge potential difference from ground until the driver touches a grounded object. This can be a problem when pumping petrol into a vehicle. @das_menschy @Wifiwits @cgudrian @LilahTovMoon @das_menschy @Wifiwits @cgudrian @LilahTovMoon DC is way more like AC than static. 120v DC is almost as dangerous as 120v AC, while 120v of static is nothing compared to rubbing feet on a carpet. (typically into the thousands) Uh, it's in a super secret extended Beta, ah no Alpha testing phase. That's it. That's the answer.  @blaidddrwg @LilahTovMoon  @jstatepost @blaidddrwg @LilahTovMoon I'm curious, why do you wrap all your text inside 🥥 symbols? @jscholes @blaidddrwg @LilahTovMoon @jstatepost @jscholes @LilahTovMoon Ah, I thought it was because of the Harris campaign's coconut meme.  @jstatepost I never even bothered asking, because why *not* bracket posts in coconuts? 😂  @LilahTovMoon And to think that doofus wants to put people on Mars.   It's like a train, but shittier. @LilahTovMoon oh my god…. Find myself wondering: Is this a design, erm, feature or a defect of that particular vehicle?  @Wifiwits @LilahTovMoon It's probably a defect; but the fact that that defect can happen and not be found and rejected during manufacturing... is the design flaw.  @laprice @Wifiwits @LilahTovMoon The whole system should immediately cut power if there current where it doesn't belong, ESPECIALLY with such obvious parts like the chassis. The fact there is no security feature that prevents stuff like this… hard to find any word describing it better than "third-world design / engineering". It's a garbage product you'd only expect off of AliExpress, simply garbage. @laprice @Wifiwits @LilahTovMoon Given all the things I heard about Musk I believe there simply ain't enough people that prevent him from doing nonsense at Tesla, like there are at SpaceX. "Drive-by-wire" also sounds like he saw some documentary about how Fly-by-wire made fighting jets more cool and suddenly wanted that for cars. @Wifiwits @LilahTovMoon Don't believe everything you see - there are many ways a vehicle can be modified to produce this unsafe condition. There are actual engineers on staff at Tesla designing and building these cars, and engineers (real engineers, not tech-bros) have an unwavering code of ethics leaning towards safety. Whatever you think of Musk, or Teslas, or people that buy Cybertrucks, please don't lump the engineers and workers at Tesla with them. @rhempel @Wifiwits @LilahTovMoon If it were common, I'd expect to be able to find more examples of it by searching. I found this, that seems similar: But I'm still not sure. @JeffGrigg @Wifiwits @LilahTovMoon That post has plenty of comments pointing to the wall connection possibly being wired incorrectly - and that makes some sense in the installer mixed something up. There is a GF interrupter in the wall connector that should trip well below the hazard level - that's why you don't die when your kitchen or bathroom appliance cord fails and you touch it. All that's out the window with an incorrect install.  @rhempel @Wifiwits @LilahTovMoon e.g. Volkswagen/VW cars won’t start charging if ground is not connected properly - so while you can’t charge them from a power bank, you won’t be able to electrocute yourself either. @vampirdaddy @Wifiwits @LilahTovMoon Yeah I totally get it about Cybertrucks and pedestrians - they really are killers. One of the reasons cars ended up with soft corners years ago was to bounce humans instead of slicing them. I suspect Elon did have a ham-handed approach to Cybertrucks.  @rhempel «I suspect Elon did have a ham-handed approach to Cybertrucks» — wait, so it's elon now, not those engineers you mentioned before? ;-) @tivasyk I realize I'm speaking out both sides of my mouth :-) Watch James May's review of Cybertruck - he clearly points out how the side body panel protrudes where it meets the hood - it's a pedestrian killer for sure. I will bet Cybertruck had a lot of engineers quit - and that vehicle was an Elon pet project - and he got his way over objections by bullying. I'm sensitive to this because I'm an engineer - and I've been put in tight design binds, but I've never compromised public safety. @rhempel "Engineers...have an unwavering code of ethics leaning towards safety." Eh. There are awful, unethical engineers. There are good ones, too. This far into Musk showing the world exactly who he is, I'm inclined to believe a not insignificant number of the engineers willing to work in his cos aren't the best or most ethical. @LilahTovMoon He should use his meter to verify that he has ground continuity from the earth pin on the charging cable. The earth pin of the socket on the vehicle should be bonded to the chassis - easy to verify with the meter. This means the vehicle body should be connected to the local earth when charging - if it isn't then there is a wiring fault in the charger or less probably the bond wire has fallen off in the vehicle. My money is on a charger wiring fault. @X31Andy @LilahTovMoon @X31Andy @LilahTovMoon @Stinson_108 @LilahTovMoon Tesla home chargers are AC - that is why you can AC charge Teslas on other vendor chargers - lookup the specification for J1772 (they send a 1KHz PWM signal to select charge speed). Fast chargers are DC but cost a fortune and are not used at home unless you have a seriously oversized supply and stupid amounts of cash. In any case the vehicle should be connected to the local earth via the connection - this is a basic safety requirement.  @X31Andy @LilahTovMoon I agree with this. It's pretty standard for automobile wiring to connect the negative side of battery systems to chassis. Something is energizing the chassis, and I'd bet it's something wrong with the charger.  @LilahTovMoon@tech.lgbt Exactly what you'd expect from someone whose family motto is "Safety third." @LilahTovMoon metal objects did this to me but because there was a grounding fault in my apartment @LilahTovMoon Spontaneous battery fires, "autopilot" crashes, doors that won't open when the vehicle gets submerged, and now the entire car body turning into a 120 volt AC live wire when charging... I have never seen a car company so committed to killing its users than Tesla. @LilahTovMoon This would not surprise me at all but I’m a bit skeptical in the video’s authenticity.   @ret @LilahTovMoon honestly thought about it some more and it might be bad grounding either on the car's side or at the people's places. the former would usually be rather unlikely but it's the cybertruck @chfour @LilahTovMoon should really be detected by the EVSE before it starts supplying power if I recall. pretty scary if not! @chfour @ret @LilahTovMoon I had this happen once to some computer cases. We were in high school running a lan party in a basement using those lightbulb-socket to 2-prong adapters with some 3-prong to 2-prong death-dapters and got a nice little tingle from the metal on our computer cases. @LilahTovMoon my wife and I were talking about this but like my old dog would get so exited for car rides he'd race to my car and put his paws on it, like imagine you forget to unplug after charging overnight? or like just your kid touching it  @Neineon77 @LilahTovMoon this is the real danger right? a amall child or pet on a humid or wet day (assuming the child is barefoot). @BryanLastRedDrop @LilahTovMoon I mean the guy gets shocked in the video and I assume he's not barefoot, it's probably powerful enough that it doesn't matter, I wouldn't be surprised if it was equivalent to or worse than sticking a fork in a socket if it's charging overnight in a garage, DC charging could be deadly @Neineon77 @LilahTovMoon I guess my point a 160 pound man can take it and laugh. a 50 lb child would get knocked unconscious (or worse) @BryanLastRedDrop @LilahTovMoon yeah and it seems like a faulty ground disconnecting somewhere so you won't know until someone gets shocked  @LilahTovMoon Anti-theft device. ;-) (Still… glad those things aren't on Brisbane streets yet… pretty sure that wouldn't meet AS/NZS:3000 requirements.) @LilahTovMoon I can't imagine this is real, but at the same time, it's a CyberTruck, so 🤷🏼♀️ Maybe they'll do a, what is it now, 5th recall?   @LilahTovMoon reminds me of an old news story about KBR's shoddy contract work causing 120V to appear on the faucets at US bases and electrocute soldiers  @LilahTovMoon Probably line & neutral reversed on the charger. But there's no excuse for a hot chassis, easy enough to detect LN reverse in the car and make it warn the user and pop the circuit breaker I keep asking if they are magnetic, but I get no answers. It might be one way to keep them off of the road.    @LilahTovMoon is that the mains voltage where you live? Cos a 240V version of that here... you don't wanna touch that. @LilahTovMoon  @LilahTovMoon There are two failures here. I would be very interested in seeing the charger because it is responsible for the second (it should ground the chassis if there is a fault like this). @LilahTovMoon The more I learn about Cybertruck and Tesla, the more I fear seeing Teslas on the road and the more I appreciate that this 7yo's take on futuristic truck is not allowed to ride on public roads in Europe.  #Cybertruck having 120V of voltage when charged? If this is an issue for more than just a few cars, #Tesla quality management is even worse than I thought.   Lots of household appliances will do that if plugged in to a miswired outlet. I've been on a job to fix that where I measured ~200VAC between a doorknob and the metal chassis of a refrigerator next to it. 🙁 @LilahTovMoon I'm not a fanboi, but come on. Got to be the charger leaking to the ground somehow. et tu @briankrebs ?  @LilahTovMoon @DemocracyMattersALot Edison: I will electrocute animals to prove Tesla is wrong about AC being safe! Musk: Hold my beer.  @LilahTovMoon  @LilahTovMoon I again question neurolink and how he is allowed to put something in someone's brain. @LilahTovMoon Absolutely bonkers. Best case scenario here is this is a one-off case of extremely poor quality control. But I doubt it.     @LilahTovMoon Yeah, but how else would you announce that you're willing to spend a ridiculous amount of money on the altar of Musk to own the libs? @LilahTovMoon guessing it's the ol' "Some rats enjoyed eating the electric cable insulation" problem, writ large...  @LilahTovMoon honestly I often wonder if some disgruntled Tesla employee wanted musk to ship a rolling Darwin Award, there’s just so many flaws. I would feel bad for the owners, but I really can’t think of a more deserving bunch of jackasses. @LilahTovMoon …. How is this not tripping the ground fault breaker in the charger / evse!?  @LilahTovMoon it's crazy more people haven't been killed or injured by these things. they're absolute trash.  @LilahTovMoon I imagine that this is an individual defect, because otherwise we would've heard about it on day 1, but still, this should not be a way that things can fuck up.  @LilahTovMoon Most likely an unshielded cable from the battery touching the body. Easy to fix, for the dealership. That car in particular is a deadly trap, also one more reason to avoid electric cars without a paint layer  @LilahTovMoon Don't believe everything you see about #EVs. The anti-EV lobby is rabid and very active in spreading disinformation. Listen to people who actually own and drive EVs.  Elon Musk: tries to convince people he's a genius who designs cars Elon: tries to design one car Elon: it's shit  @LilahTovMoon Ehhh I think the charger is miswired such that its neutral lead is tied to 120V household outlet. Where is this video from? What does the other end of the charger cable look like? @LilahTovMoon I'm no fan of Cybertrucks, but the second clip feels fakey to me - him holding what looks like an ammeter near the charging cable seems. Even not clamped around the cable it could be picking up a reading. @LilahTovMoon I'm kinda dubious of this. When I plug my Model X in to charge, instead of coming on immediately, it takes about 10-15 seconds to start charging after the handshake between the car and the charger. The video shows the truck having voltage immediately.   @LilahTovMoon@tech.lgbt Honestly, I don't believe this. Someone could just be touching the metal on the other side with an exposed cable in the right timing.  @LilahTovMoon I can not apprehend the confusion that permitted such a flaw to exist. The body of the Tesla should be connected to Earth ground. Hot/neutral should be isolated and equal currents so GFCI detects a fault. If somehow Earth ground was swapped for hot, charging should not occur, but the body could be hot. If Earth ground was swapped for neutral, the body should not be hot, and GFCI would detect a fault. There must be damage in the charger.   @LilahTovMoon The guy's name is Braden Smith. He's a farmer in Idaho. In this local news story he sounds pretty happy with his Cybertruck. Anyone who's on TikTok can check out his account there. He says that he makes videos to amuse his followers and is keen to raise his follower numbers. @LilahTovMoon This news article includes some of Braden Smith's other TikTok videos, showing how he uses the Cybertruck for farm work. https://www.teslarati.com/farmer-proves-tesla-cybertruck-amazing-work-truck/ @LilahTovMoon that’s terrifying. Imagine brushing up against someone’s car to find it it’s live.  @LilahTovMoon It's a feature to more easily be able to put a better coating on through DIY electrolysis at home. |
@LilahTovMoon JESUS CHRIST LMAO
