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.

    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.

    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.

    You 100% can plug in an unpowered mobile connector and drive away. If it's not actually on a circuit, it does not detect it, does not light up, and does not lock the charger (the plastic notch underneath).

    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.

    At the same time, I've wondered if it would be helpful for EVs on some long-distance road trips to tow/stow a generator for overnight and emergency charging. Charging stations are popping up more and more, but if you're saddled with an obsolete or under-served charging port type (e.g. Nissan Leaf), having a generator would be valuable insurance.

    Every EV can just hook up with a (mostly) passive adapter to any outlet and get a charge. It won't be fast (especially if you are cursed with a 110V outlet), but even in the boonies an overnight trickle charge will get you to the nearest fast charger. Just get the relevant adapters for your car.

    This is basically what your generator would do except you want to lug it around instead of leveraging the cables that we pulled within driving distance of everywhere but the most remote trails? The whole point of electricity is its versatility and ubiquity!

    FYI using a wall plug to charge an EV is a perfectly normal thing to do. For a small(ish) commute, regular 220V@10A is way more than enough to get back to full overnight. It won't give you 500 km of range, but only freaks and truckers drive 500 km every day.

    When I've crunched the numbers in the past, more efficient EVs would get something like 50 miles overnight for a commuter with just a 120V outlet to work with, so if you get one full charge over the weekend, it'll still be fully charged by the next weekend if you didn't deviate from your commute, or a maybe a bit lower if you did.

    Mostly right but in the US we have way more dead zones, and we also have 110-120v outlets in most places. There are 220-240v outlets, but mostly only for electric ranges, dryers, and big AC units, and almost never outside a house or hotel. And charging at 120v 20amps does kinda suck. About as much as using this generator would.

    That's all true. And FWIW, I've only ever charged my EV on 120v at home, so I'm familiar with the limitations.

    I'm thinking of the worst case where my trip planner accidentally sends me to a location where the intended charger is long gone or in-use, and I have too little charge to make it to the next viable location. Also: it's 3AM and nobody is open. Sure, I could sleep that off in the car and/or throw myself on the mercy of some hotel, but that's sketchy in other ways. Or maybe I'm stranded due to a moment's inattention?

    To me, that all reduces to "be resourceful" so why not pack some additional resources?

    They're doing it wrong. They need a small wind turbine on the back. As they drive, the turbine spins, producing energy which charges the car, which is then used to drive, which further spins the turbines! There is no flaw to this logic! /s

    so out in the utah salt flats they're always trying new and ridiculous looking things. There was a vehicle i remember seeing similar to this one:

    the turbine was in the back and the wind provided all the motive force for the vehicle. and it worked! And the blades were not contained so it could chop the fuck out of something that got too close, absolute deathtrap. but powered by wind alone so if you had the right geography, like you live in wyoming or something you got a free ride. pop class 2 electric hub motor on that for windless days, fix the deathtrap part and you have an ideal vehicle if you ask me.

    A couple manufacturers were showing off EREV at the big manufacturer auto show, basically EV with a small gas engine to extend the range. Less motor than a hybrid, but enough to get some pretty ridiculous range out of a single combined charge/tank. Basically what this image is implying.

    Seems like a decent idea for people that use their vehicle for longer distances.

    BMW did it long ago in the i3 with the range extender. Not the best attempt though. They made it tiny, but it still had a heavy battery (though obviously not a very big one, just heavy for a car of this size), so to get the weight down, they used carbon fiber, but it was supposed to be an economy car and now with carbon fiber it was expensive.

    Idea itself is not bad though.

    Basically! The gasoline engine could provide some of the needed energy while driving to reduce battery drain but not enough to keep up with the motors' energy consumption. It still needs to be plugged in to charge and can be driven in pure electric mode for short distances

    I've been asking forever why we aren't seeing gasoline electric vehicles. It's literally been standard practice for diesel locomotives for basically as long as diesels have been dominant, you hook a gigantic diesel generator (prime mover)to a pair of gigantic electric motors (traction motors), and when you want to slow the consist without consuming your precious air for more intense braking, you can just turn the motors into generators and dump the energy into giant resistor banks on the roof (dynamic braking) or into an battery powered engine behind your diesel electric engine

    You get the power of electric motors, the mechanical simplicity of electric transmission, and the range and rapid refueling of an internal combustion engine. The disconnect between the prime mover and the traction motors means each can be tuned to their respective efficiency curves (especially if a bank of batteries/capacitors is included as a buffer) so you get more efficient idling, more efficient acceleration adds the options of connecting slugs (units with no prime mover nor control cab) or b-units (units with no cab)

    They're called hybrids. The reason they're not in series is because it's more efficient once the engine is at "cruise" speed to just let the engine spin the wheels directly instead of losing 15% going engine to electric then electric to electric motor.

    So instead of a transmission, hybrids use a planetary differential. That way everything is always spinning at maximum efficiency.

  • [–] 1 point 8 months ago (1 child)

    I suppose I could see how that could math out, assuming the engine running at an appropriate RPM to transmit to the wheels isn't less fuel efficient than an engine running at an appropriate RPM to generate electricity.

    The thing that turns it on its head for gasoline electric though is the IC engine can be almost anything and do almost anything if all it's doing is spinning an alternator with sufficient power buffer before the electric motors. The IC engine could run at a single constant RPM at all times if that's most efficient, or it could be a more car-like thing that adjusts it's RPMs based on load. Or maybe it runs at constant RPMs but the count of active cylinders changes depending on load. The types of engines that can be used suddenly becomes immense because of this too

    I just find it hard to believe that the most efficient option for a hybrid is 2 drivetrains. That always struck me like it was more engineers specialized in ICE vehicles simply designing what they know rather than something more bold and imaginative

    That's exactly what the car does in real time. My Toyota switches constantly between the ice engine transferring energy to the electric motors and the electric motors turning off when they are outside of their most efficient range.

    It has an onscreen graphic to show you while you drive for the curious. It has another screen that gives you a driving score to encourage a driving style that maximizes efficiency like having the battery recharge more by braking longer and smoother.

    It can be plugged in with the generator on, so no issue. Not that this image isn't fake as fuck - the generator isn't secured, and it's connecting the AC generator plug directly to the EV port with a cable instead of using an EV charger.

    Germany during WWII did something kind of like this. They modified some of their cars to run on wood gas and they would tow a wood stove on a trailer that generated the gas, with an attached hose that would feed it into the engine. A sensible plan when your only source of oil is Romania and all of your horses have been requisitioned by the army for its "blitzkrieg".

    They're an interesting thing to say the least. Finland had a lot of wood gas generators in use during WWII as what limited petrol we had went towards the war effort. Other substitute fuels were used a lot as well, e.g. pine turpentine which we had a lot of as it's a side product of refining wood into pulp.

    It's a relatively efficient system, and burns quite cleanly in the engine (as soot and other contaminants are filtered out by the generator). Though they're quite dangerous, since wood gas is mainly pure carbon monoxide. The amounts they produce are so high that leaks or topping up the generator can cause carbon monoxide poisoning even when outside. In Finnish we actually call the generator häkäpönttö, which in English would be a carbon monoxide can (häkä colloquial Finnish for carbon monoxide, pönttö a colloquial Finnish word meaning a can, container, carton or someone dumb in a usually non-derogatory way – closest equivalent in English would be dummy).

    Yeah that's actually how I googled it. Couldn't for the life of me get "wood stove generator" into my head but "häkäpönttö" is easy.

    And I'd agree that, like many Finnish words, it doesn't properly translate. A pönttö would be closer to a barrel, I'd say, than a can. A can sort of implies a smaller one. Although yes, "garbage can" would be a can as well and nearly on a similar scale as a häkäpönttö.

    It's sometimes crazy hard explaining all the implications of a given word. You know them but listing them would be hard.

    But yeah especially with how much forests and forestry we have, it was a very good solution in WWII. We needed the proper petrol for all those tanks we stole from the Ruskis. We started the war with genuinely a few old Pösö tanks from WWI and stole most of what we had by the end of the war. (That's Peugeot for non-Finns haha)

    Good point with the barrel, truth is probably somewhere between the barrel and a can. After all, there's also pönttö, both vessan- and linnun-, which again are on the smaller side. I kinda love how much nuance and double meanings there are in especially the spoken language.

    True meaning can only be grasped with enough exposure.

    Didn't we also have some Vickers six-tonners at the start? Next to useless by then but probably could penetrate at least a BT-5.

    Edit: now that I think of it, a canister probably fits quite well between the sizes of can and barrel. But to me it would then be a closed container, which a pönttö doesn't necessarily have to be.

    Ture, "bird cans" aren't especially large. But they're not like beer cans. You could never really say "annappa se kaljapönttö" unless you were talking about a barrel or a small bucket of beer.

    Didn't we also have some Vickers six-tonners at the start?

    If you say so, alls I remembers is one of the tanks we stole from Russia is still being prominently displayed in the Häme Regiment base in Lahti... checks on his facts Fuck, I'm too old for this shit. The Häme Regiment (HämR) was a regiment that was shut down in 2014. I mean, it was about time. But I'm still curious as to what happened to the tank I was talking about... Well, say what you want about LLM's (and they do sort of threaten a lot of society but) but it was pretty good in searching for info like this. I explained to Gemini where I did my service and asked about the tank.

    ​Where is it now? After the Häme Regiment was disbanded in 2014, most of the heavy historical equipment was moved. That T-34 was relocated to the Parola Armour Museum (Panssarimuseo) to ensure it was preserved and maintained, as the Hennala site transitioned into a residential and civilian area.

    So yeah. Anyway, my point was that I just remember reading the sign saying how many we took from the Soviets. And also our lieutenants and whatnot military fanatics giving us some history on them. Then I couldn't remember the number years after so I googled it and saw we only had some puny WWI tanks before. Honestly, I don't even know what a Vickers six-ton is, but I'm guessing British..? (Because I do know what a Vickers gun is) Checking.

    Yah. Thanks for the info.

    Finland – used 33 tanks since 1938 (including an evaluation tank). They were bought unarmed, without optics and radios. Some were armed with short-barreled 37 mm Puteaux guns and later equipped with 37 mm Bofors anti-tank guns as their main gun with a coaxial turret MG and a "tank SMG" in bow plate. They were used in the Winter War with the USSR. After this war, the Finns rearmed Mark E tanks with captured Soviet long 45 mm guns and DT MGs as used in the T-26. The Finns designated the rebuilt Vickers tanks logically as: T-26Es. They were used in combat from 1941 to 1944 and remained in service as training tanks until 1959.

    Oh yeah.

    So about half and half apparently:

    Before the Winter War (Nov 1939), Finland’s tank forces were minimal, consisting mainly of 32-34 obsolete Renault FT-17 light tanks (acquired 1919) and about 30-32 recently purchased Vickers 6-ton light tanks, which were still being fitted with armament. They had no medium or heavy tanks

    So we had like 60 light tanks. By the end of the war we had captured and destroyed, quite a few.

    Oh yeah and about the languages, yeah, if you speak both Finnish and English fluently, it's awesome what weird shit you can combine because of the different natures of the languages. My friends used to think me a bit pretentious for inserting English phrases or words into Finnish, but that was like 10+ years ago. Nowadays most speak Finglish pretty fluently and it doesn't matter if you add a bit of London while completely speaking Finnish, as long as you're not doing it just to be pretentious, but because the word/phrase suits better (or you've just forgotten the Finnish word, which happens to me quite a bit nowadays.)

    There is a huge missed opportunity of having modular battery packs that you can load into EVs.

    You don’t need a huge battery for everyday, in fact it makes your drive less efficient.

    What if there were standards and you could go to a gas station and rent some packs. Put them in the trunk (there would be slots and/or standard connectors), and then drive off.

    Once road trip is over you return the packs (or you could buy instead of rent).

    You can also just swap the packs in gas stations with fully charged equivalent, making long trips more flexible.

    I think china did something like that with scooters.

    There were attempts, but suvh a system just doesn't work reliably. The pack has to be replaced by robots since it's under your car (has to be due to space constrains and more importantly weight), and the amount of moving parts, reliability and safety concerns were a constant issue.

    For scooters it's no problem given the way smaller size and optimal position inside the chassis, but for cars this concept hardly works properly.

    This is a good idea, though.

    Piston engines are way, way, way more efficient (and cheaper to make) when optimized for one RPM and a static load (like a generator). They can be tiny if running at 100% throttle all the time; a few horsepower is enough. Excluding the transmission saves weight/cost, and a generator for a few horsepower isn’t that big.

    Yeah, you get electrical loss, but everything else more than makes up for it.

    I suspect "tiny battery+generator" EVs aren't a thing in the US because:

    • It doesn't sound or drive like an ICE car. It still has a battery, so gets all that range/durability "anxiety" associated with being an EV.

    • It's associated with all the issues of ICE-based hybrids.

    • It's not "all-electric," not quiet, so it's not percieved as a luxury car like pure EVs generally are.

    • The cars that do implement this tend to be smaller, so not marketable here in the US, apparently.

    • Factories are still tooled to make ICE cars en masse, not EV drivetrains.

    In other words, it's all perception and marketing. And I think, sadly, it's true: people wouldn't buy them here in the US.

    You do see them outside the US though.
