For things that are "hmmm".

Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

I’m not sure about this, surely an EV wouldn’t allow charging while in motion as a safety measure against driving off while plugged in?

But then, there’s this photo right here unless I’ve been suckered into believing AI edits again.

Tesla won't you put it into drive if the cable is attached. Even if this is some hacked firmware, that tiny generator will give you like 4mi of range every hour. Definitely a meme.

[–] Rooster326@programming.dev 1 points 3 hours ago

What if you plug it in after it is in drive?

[–] MartianSands@sh.itjust.works 38 points 7 hours ago (3 children)

Yeah, that's supposed to be impossible. Either they're not moving and it's a staged shot (unlikely, since they're in the middle of traffic and there appears to be motion blur), or they've fiddled with the car to make it think the charging door is closed, or it's an edit.

I'm suspicious of the motion blur, personally, because the traffic looks too tight to be moving much, so I suspect an edit

Giving the photo the benefit of the doubt, it's also possible that this Tesla owner had to bring a generator somewhere for unrelated reasons, and thought it would be "funny" to hook it up to the charge port on his car as a joke.

[–] MartianSands@sh.itjust.works 12 points 7 hours ago (2 children)

My point is that wouldn't work, unless the car was in park. A Tesla will simply refuse to move if a charger is connected

[–] ThePantser@sh.itjust.works 17 points 6 hours ago (1 children)

That's not a charger though. EVs can't take the direct power from a generator. It needs to communicate with a base. So that "cable" is impossible and is a joke.

[–] MartianSands@sh.itjust.works 7 points 6 hours ago (1 children)

Doesn't matter. The car knows something's plugged in, even if it can't talk to it

i found a higher quality version, not sure of the original source, and its definitely AI:

regardless though, i did look into if this is possible. no matter if the connector on the vehicle is NACS/SAE J3400 (the "tesla" connector") or SAE J1772 (CCS 1), for AC charging—which is the situation here—it will be the same (note that this will not exactly apply to vehicles using CHAdeMO, GB/T, etc.). i went with this document that briefly outlines NACS. this is the proper standard, but i wasnt able to find a copy gratis with my two minutes of searching. this should still apply to other vehicles with a CCS 1/J1172 connector, at least for AC charging!

now, since we are charging with alternating current, we have only five pins to deal with, seen here for NACS (for CCS 1, just ignore the two super giant pins, if present. otherwise it applies to CCS 1 too!):

the big two (HV + and HV -) are for supplying power, no matter the flavor of AC or DC at hand. with CCS, DC charging goes through the two big pins at the bottom, AC charging works the same way though. the ground pin is present for low voltage electronics to actually have, well, a proper reference to ground! (this is your zero volt pin).

finally, we have the control pilot, and the proximity pilot. the former is a digital interface for the vehicle and charger to communicate in depth about charging speed, battery status, etc. the latter however, which is of the greatest interest to us, handles the physical connection itself. this is where the name comes from: it handles when a charging connector is in proximity (plugged in) to the vehicle!

when measuring between the ground pin and the proximity pilot pin, if the vehicle is ready to accept a charging cable but none is plugged in, there will be five volts. if there is something compatible plugged in, resistors within the connector will pull the voltage down lower (to 1.5V), indicating that something is, well, plugged in!

here is the part of the charging connection schematic that is relevant to us:

R1 and R2 are just resistors (150Ω and 330Ω, respectively), and S1 is a (optional to implement) normally-closed switch—likely a button on the charger plug handle—that brings the voltage slightly higher (to 2.8V), to signal to stop charging and if possible, unlock the connector (if it is locking).

now, the resistors themselves are located inside the plug, and not the charger/power control unit. after all, if the vehicle manages to somehow move away, and the cable snaps off said unit, the vehicle can still be aware of if something is plugged in!

of course, if you want to defeat this, it is very simple: tape over the proximity pilot pin! as far as the charge port door goes? from forum posts i've seen, the vehicle will still drive, even if it's a little whiney.

"but wait!" you say, "the vehicle can latch the connector into itself. can't it just detect it that way?"

this would certainly vary by vehicle. for teslas, it likely can't (or if it could, the engineers didn't bother to). seen in this youtube video, the charge door slams into the object left in the charge port, indicating the vehicle probably doesn't look at this.

i also looked up the electrical schematics provided by tesla here (SVG):

the block on the left is the vehicle-side charging port assembly, the right is the actual vehicle computer. the three pins at the bottom handle the connector latch: X312-1 and X312-3, which power the motors, and X312-2, a switch/button in the port which is presumably what the vehicle uses to know it latched onto something successfully. remember, this is for the latch the vehicle extends—not the one that is simply mechanical and operated by the driver—and most likely does not provide enough information to tell if something is plugged in.

overall, if we are talking about teslas, your point does hold some merit; even if you snipped the charging plug entirely off a cable, the vehicle can still (if the plug is up to standards) detect it if it's plugged in. however, something like this would not be unrealistic, even if the vehicle didn't actually charge.

of course, this may not be the case for other vehicles! but that is beyond the scope here :)

While EVs won't allow starting the car whilst charging, they will allow the charger to be open, and the cable is likely a dummy so wouldn't be registered as "plugged in". Thus allowing this joke outfit to drive around like this.

[–] MartianSands@sh.itjust.works 0 points 6 hours ago (1 children)

I own a Tesla, and I also own a broken charger. I assure you it won't let this happen

[–] lazynooblet@lazysoci.al 13 points 6 hours ago (1 children)

Just went out to mine, plugged a cable in with nothing on the other end. Could pull off fine

I went out to mine and realized I don't own one so I have nothing to add to this conversation.

[–] MrQuallzin@lemmy.world 7 points 7 hours ago

My guess is that it's staged in that it's how they've "dressed" the vehicle and are doing it for laughs

[–] unknownuserunknownlocation@kbin.earth 7 points 6 hours ago (1 children)

It's also entirely possible someone had to transport that generator and decided to have some fun with it and fuck with people.

[–] keyez@lemmy.world 3 points 5 hours ago

Generator doesnt look to be strapped down or secured to anything I think it's been shopped or edited in.

[–] Diplomjodler3@lemmy.world 4 points 7 hours ago

You're absolutely right. This is just a fake.

Last I heard it was a performance art piece to illicit this type of conversation about where the electricity comes from.

[–] mech@feddit.org 7 points 6 hours ago (1 children)

That's a stupid conversation, though.
Electricity is made in huge power plants, which are a lot more efficient due to their size.
And a wider EV adoption allows for more renewable energy generation, since their batteries can act as a buffer to balance out the power grid.
With a smart meter, you can set your charger to draw power when the price of electricity is low (like when the sun is shining and its windy, so renewables produce a lot of power). Thereby consuming the peak power output.
And when there's no wind and no sun, you can sell a part of your battery charge back.

[–] TheAsianDonKnots@lemmy.zip 2 points 6 hours ago

I think most art is a stupid conversation. Ever try to disagree with an artist? All they heard you say was “blah blah blah something about you being a consumer sheeple.” It’s maddening when it almost always boils down to “do you like the art or not”… or it’s money laundering and they don’t give a fuck.
