Tow Charging Tesla at 70MPH for 25 miles
Vložit

- I tow my Tesla with another car while using full regenerative braking at 70 mph for 25 miles, at this speed the batteries are being charged at 65,000 Watts, I did not think this is going to work as well as it did but turns out this might be an option for a lot of Tesla owners if they get stranded.
I know there was a lot of talking in this video and it was kind of long, but I felt it was a very important video because it can possibly help out a lot of Tesla owners, most of the Tesla owners I talked to were terrified of running out of battery power because they said they would either have to have the car towed by a tow truck or wait for Tesla service, and to my surprise none of that is necessary.
I mean the range anxiety of these cars is very real and it is not a good feeling so I'm hoping that this video helps someone.
also I was very sick when we filmed this video, that's why my voice sounds sort of muffled.

Tesla's ecu was thinking damn this is the longest down hill in the world
Lmao
mustve been the hill Trevor Milton used to test drive his Hyliion 🤣
Downhills like these are very common in my country, some are 50+ miles long but they are motorways down mountains. My hybrid shows 99 miles per gallon average going down them and that's only because the calculation maxes out at 99 and it's down basically infinite range due just going downhill + charging.

Pick up speed and roll in neutral. This is what extend s range. Try this buddy. Namaste namaste
The E55 supercharger became a Tesla supercharger 😂
🤣🤣.. that's pretty accurate! Without that supercharger I bet you it would have been struggling
@@WarpedPerception Put the Lexus 450 hybrid transmission in the merc (upto 350hp available with the right battery )it could lower the tow car fuel consumption or shut down the ice engine from 0-45mph or just run on 4 cylinders + transmission 45+mph all 8 when accelerating for hills/passing... just needs an ecu to do it...
@@kylereese4822 *Mercedes
We also don't call it gen
@@WarpedPerception I would only do that if I was stuck on a highway and supercharger super far away because the gas mileage is horrible on the Mercedes when towing. I don't own a Tesla but I think that due to gas prices never do that unless a supercharger is like 50 miles away.
@@WarpedPerception I'm just imagining flooring my 44kw Citroen C2 in second gear trying to pull the generators in that thing at 50 mph. It might be more efficient in first at 20-25 mph actually due to less rolling resistance and air resistance.
"Marty, if my calculations are correct, when this baby hits 88 miles per hour... you're gonna see some serious shit."
Careful now, you will give Musk ideas
@@Ryanthusar haha true
Yeah! No recommendation by Tesla Technicians
This made me laugh
Please explain
Should have a symbiotic relationship with truckers, where you help them descend steep hills with your Tesla brake, and you get a free fully charged battery.
Not sure how strong Tesla semi regen braking is, but imagine how much energy could be recouped if Tesla semi didn't even have to use its disc brakes on steep downhills.
Cool idea, but I’m not doing 70 down a mountain.
@@TidalWaveDan I do 80 down a mountain lol
@@ValoPlay724 probably more if it could downshift and go slower
@@ValoPlay724 you might be able to take the empty lorry back up the hill on the charge from the full lorry going down!
What I'm more impressed with is the E55. Most cars can't handle running at that power level without overheating quickly. Your E55 managed a good 20 miles with a heavy throttle the entire way. Impressive!
Yeah, I prefer that to the battery operated thingy
@@Markcain268 the E55 is a lovely car. Almost a little sad that the Tesla would walk it without breaking a sweat, lol!
@@ender4555 who cares about that when you have a lovely V8 to play tunes on?
I mean, in America, you can find a V8 pickup on every corner that can handle a bit of towing. If you can convince someone to tow you for a bit, you have all the charge you need. This is a pretty awesome trick tbh. (May people never need it.)
* This trick wouldn't really work elsewhere in the world. It's super rare to find a powerful engine in Europe. Like, even a Ford Raptor has a poop 2.0L I4 EcoBlue engine. Yepp, that huge chassis/mass with a tiny crap engine. So, good luck finding something that's powerful enough to pull and counter the breaking power. I wouldn't even dare to attempt this stunt with my 2.2L TDCi car. Just not strong enough lol.
Its a mercedes so its tested at VMax. So it shouldnt overheat at all. Some of them might even be driven at topspeed for 3 hours as that is not that uncommon in germany.
Just needs a lasso system for semis as they wouldn't notice at speed.
Lot of truckers out there will help stranded drivers if the driver has a tow rope and help them out to the next gas station. I cant see truckers out there not willing to help those driving electric vehicles doing the same thing.
@@Ryanthusar Um, no, absolutely not, and that's why you've never seen a trucker towing anyone. Way, way, WAY too much liability.
@@CORZER0 I have seen truckers tow vehicles around here. A !longer strap is used so they can see them. But with the Tesla on regin then it is breaking already as well so if a sudden stop is needed it is already half way there. Plus the auto pilot safety system would engage to hit the brakes
Get a big magnet behind the bumper (fender in US English :) )
@@RaglansElectricBaboon No, it's also bumper in US English lol. Fenders are the parts of the car body above the wheels
The Benz wins the prize in this video! To tow that much weight and not destroy the transmission or rear wheel bearings is amazing! Greatly appreciate your courage to do this video! You know you’re kinda crazy right!? LOL
That's a great point I didn't thing of, it was towing under load the whole time with all that resistance.
There would not really be any extra load on the rear wheel bearings. There was no extra weight on the merc. It was putting out a lot more tractive effort but that is not the same as putting the weight of the tesla on the rear axle of the merc.
@@WarpedPerceptionhow is this going a year along did it break your Tesla
Imagine seeing someone tow a Tesla into a gas station 😂 I wonder what those people were thinking
Maybe something like, „There is a benz towing a tesla.. and it is getting gas at the gas station“
@@mm-hl7gh Not to mention a Tesla taking up one extra gas stall. But hey, it'll be some rarity for people to talk about!
Being familiar with the town that gas station is in, if they even noticed, "eww, why didn't they just call a tow truck"
Rich, this is your solution for your disabled Supercharged Tesla. Maybe one day he will pull with his new frakenstein ICE-T Tesla.
Just put it on some rollers to spin the wheels.
If he finishes it.....I mean he has a better chance than the chicken farmer down in Florida
I was thinking the same thing! 😂🤣
You should go somewhere with a mountain pass, and see how much charge you get going down the whole hill
I've noticed 1-2% increase from regen in the West Virginia mountains...
@@worthypook thats so cool. Regenerative braking really is understated as a technology
dont forget to do some tesla dorifto
I wonder how much Regen you could get if your job was at the top of the mountain and you could Regen your way down every day, obviously you'll use up battery going up, but if you could Regen 50 percent of what you use I'll consider that a win
@@rigon28 You will consume, to say 29% up hill, and down , maybe will generate 2 or 3%. The car will slow down during regen, and stop. You will never find the road with so slope and so long to sustain regen from 14% to 55%. In this video they talk only about recharging, but this happened because of constant power pushed by Mercedes which I guess the gas consumed was double.
Anyway this is not realistic. I will never tow a Tesla car for this purpose.
And that kids is how a gas powered generator works.
You tow it behind a car?
@@ohanaross-roberts97 yes I do, you got a problem with that buddy?
A gas powered van, towing a diesel generator, charging an electric car. The future is stupid.

I love that car

65 kW of the braking force is quite a challenge for torque converter of this E55
But Mercedes is Mercedes! Especially back that models
5 miles to the gallon lol
I imagine this is not anything more straining than doing 130mph continously, which this car is made for.
Mercedes is one of the most unreliable and expensive cars on earth to maintain. I think a manual F-150 would be smarter.
@@uclajd That's pretty ignorant generalization. Mercedes has some fails but also has bulletproof machines under its belt.
@@PuerRidcully LOL follow Scotty Kilmer's channel and tell me that overpriced, over-engineered Benzes aren't SHIT. Depreciate like Venezuelan currency! Shit!
Hahah, props to the Benz for holding up to that! That's a lot of load!
but.. it has like 470 or so hp. why would 65kW (90 or so hp) be a problem? with that speed no torque converter losses and the gearbox should be able to handle all the 470hp just fine. so... ???
@@RubyRhod it’s not the engine, I think Matt was worried about overheating the transmission. The Model S is a heavy bastard
@@RubyRhod Having gobs of HP doesn't just perfectly translate into towing capacity. There are all sorts of additional stresses put on the drive train that it was never designed for. Stress on the transmission (and over heating it) are the biggest. There's a good reason why big trucks have super beefy trans/diffs and usually added trans/oil coolers. 96HP of load may not seem like much when you have 460HP, but that's a Honda civic pulling you in the opposite direction the whole time.
1.0 ecoboost has more power than 65kW. Of course it wouldn't be able to handle drag of towing and moving itself at the same time.
@@ender4555 luckily the mercedes' transmission has an oil cooler, and if i remember correctly the 55amg's have bigger coolers than standard models
Pretty cool to see 20 miles of regen enables 160+ miles of driving distance
This man is a legend and his assistant is spectacular,
Well done to Benz as well, quality all around ..
It feels like it became the world’s longest haul hybrid vehicle. It’s like those jets that get refueled in mid-air. Really fun video, love pushing this kind of tech to its limits.
How many miles per mile does this recharge? (Miles of driving per mile of towing)
EDIT: looks like about 4 miles per mile? That's pretty good
Yes you nailed it, that's about what it charged

Pretty sure he’s talking about Jakub’s (The Straight Pipes) Raptor towing Jason’s (Engineering Explained) Model 3 Performance 😝
Definitely. Pissed me off a little bit that he kind of dissed their video. The purpose of their video was to get actual data like real information. They already knew it would work it was a matter of doing the calculations to find out how much energy was consumed by the truck versus was put in by the car etc and to do that they needed to run into constant speed which you can do on a track.
@@kens97sto171 it was weak though. Kinda missed the point when you don't go the extra mile. No pun intended.
Business idea: Start an ev towing company for people doing road trips, ev drivers won't have to pull over by the road for hours on end to charge.
I was thinking the same thing, just like air-to-air refueling.
Kinda defeats the whole point of electric cars.
@@YousefMoham3d Towing cars are also Electric .
@@Y2Kvids The whole thing is gonna be extremely inefficient even if the towing vehicle is also electric.
@@YousefMoham3d you saw the Merc guzzle through the gas ? Same thing. But geared electric trucks should be used.
I like your thinking. Was thinking about mpg etc but you covered it all in the video cheers!
5:20
Okay, I want to make an uneducated guess and try to do some calculations with numbers I don’t have a clue about. Sound terrible, right? Anyways, here we go…
so… 5 mpg are 47,043 l/km
and such a car would use anywhere between 10 to 15 l/km on its own at such a speed of about 70 mph (112,65 km/h), which is not all that fast. From quickly looking at forums, a consumption of 12,5 - 13 l/km seems realistic.
So… this means…
best case (smallest mpg drop):
from 15 l/km (15,681 mpg)
to 47, 043 l/km (5 mpg)
probably somewhat realistic (regular fuel consumption may be assumed a hint too low):
from 12,5 l/km (18,8172 mpg)
to 47,043 l/km (5 mpg)
worst case (largest mpg drop), rather unrealistic (it very likely consumes more than 10 l/km normally):
from 10 l/km (23,5215 mpg)
to 47,043 l/km (5 mpg)
I also want to mention that mpg is absolutely not ideal for this, since a drop of 1 mpg isn’t always the same increase of consumption. A drop from 51 to 50 mpg is much less of an increased consumption than a drop from 6 mpg to 5 mpg.
a little addition: original question of the comment I replied to was how big the mpg drop was. And that is what I focused on with my answer.
@@herrkeks8509 that was helpful thank you . yes the mpg measurement isn't precise as L/100km
@@oussama4629 No problem. :)
and indeed, I meant L per 100 km… I didn’t make that clear, but indeed, I obviously meant per 100 km (not per (single) km). :)
@@herrkeks8509 lool i never understood why they choose mpg over L/100Km
That tesla thought it was going down the side of a mountain lol nice video as always
That was a fantastic idea Matt. Innovation at its best!
I love the moment when she said "OK, im speeding up" and the engine sound was amazing. ❤❤❤❤
In Italy if you tow like that, you go in jail for sure.😁
This is why america is better 😎
I love italy, I'm currently eating Italian cookies, but you are absolutely dead on accurate, I'm sorry to say but this is why I love the USA!!, I love my Country 🇺🇸
Well I'm glad I don't live in Italy then, I wouldn't be able to do anything... the police here have better things to deal with to be honest
This test was way better than the one done on the track thanks for posting
😊 thank you
Love the channel dude, was a skeptic years ago, but you responded to my admittedly rude comment and explained your point of view- keep it up
Imagine if trucks had some sort of latch on the trailer that you could catch onto and charge up for a bit then release when you want 😂😂😂
Which would defeat the purpose because of the inefficiencies. In effect, he made his vehicle even less energy efficient than a gas guzzler. It's like the world is moving backwards in intelligence. "Look at me and my fancy smancy energy saving vehicle that's soo green and saving the environment!", "...Also, I make it use more energy and cause more pollution than the gas powered vehicle it replaced".
@@peoplez129 you're missing the point. He generated the electricity by using another vehicle. That vehicle wasn't necessarily built to tow a car that basically has its brakes on (the motor resistance while charging)
If you had a huge truck. That Is already used to hauling dozens of tons. It would make light work pulling a Tesla. There could be a currency exchange system between the truck and the Tesla too for the extra fuel used. If the truck is only carrying light goods then there's more torque on reserve.
Plugging into a socket still requires the electricity to be made by power stations...
@@MaNNeRz91 I'm not missing the point. You're clearly missing the point. So we're going to create electric cars....and then have essentially wheel treadmills to transfer energy to them? It defeats the whole point of having an electric vehicle in the first place. If this actually became a service for electric car owners, it'd be a joke and a slap in the face to the whole green energy movement. Might as well not even have electric cars at that point.
@@peoplez129 but how many electric lorry's do you see? 🤦🏻♂️ There's barely any at the moment. So for now. It would work. Not only that. without knowing how much pollution it takes one tesla to fully charge from empty at a charge point. you can't make any assumptions on how green it would be compared to using a lorry which is already travelling and using fuel and hauling weight.
@@MaNNeRz91 He's just mad about electrical vehicles existing. He's not actually making any logical points. Don't worry about it
This was super interesting!
I saw in your comments that the Tesla charged about 4 miles per driven mile.
Sounds like a win-win situation, because you travel the direction you want while charging the vehicle at the same time.
That's what I thought too, win-win situation but yeah your numbers are pretty close
@@WarpedPerception I’m very curious what the price per Kw would be when factored in the fuel cost.
*calls tow truck company* “hi, I need a tow truck on the side of I-40 at mile marker 60”
*tow truck arrives* “yeah so could you pull me for about a half hour or so? I just need alittle charge.”
*gets pulled for a half hour* “alright, that’s good thankyou!”
*tow truck out of fuel after pulling Tesla💀💀💀*
no the tow truck wouldnt even notice a fuel loss, those big ass heavy disel trucks are meant to pull 8 ton+ vehicles and have alot of toruqe.
@@TAKIZAWAYAMASHITA its a -87 horsepower load, thats a heavy load, it would def notice
@@zachary6656 forgetting to account for the torque of the engine that's what makes you get going and aa diesel has plenty of that..
James doesn't know what he's talking about. Torque isn't relevant here.
Zach it depends what the air resistance load is on the truck going 60mph. If it's taking him 80hp to go that fast then it's only doubling. But if he was going 80mph it might be 160hp to get over the air resistance then he wouldn't notice much. Tow trucks don't have particularly good aero but I have no idea how much power it takes them to go that fast and it sounds like you hadn't considered that either.
I’m imagining someone on the side of the road with a Tesla up on 4 jacks, furiously spinning a wheel with a hand crank trying to get a couple miles worth of charge.
Pushing it 20 metres huffing and puffing, then getting in and driving 20 metres till it conks out, then repeat.
For the most part, the maximum towing speed is usually about 10 miles per hour lower than regular posted speeds. This usually ends up as a 55-mph max on highways.
Wow, flat towing like that is illegal where I'm at, especially on the highway. I'd rather pay the tow bill than the ticket for that, but if it works in a pinch
I honestly think it's like anything else, even if it's illegal where you're at if you really need to get a car out of the way for instance if the car stopped right in the middle of the freeway, I highly doubt the police would tell you anything with trying to create a safe situation or get out of a bad one.
@@WarpedPerception if anything, less work for them, get the damn vehicle out of the way and then it’s your problem not theirs
@@WarpedPerception If either of you need to make an evasive maneuver at 70, both cars are doomed for failure. It is literally more unsafe than leaving the car. Flat towing at 10, 15 mph? Sure. 70? You're being absolutely reckless.
@@supertoaster94 It took far too long for somebody to point this out. Towing at that speed is absolutely INSANE and massively reckless.
I've been getting people riding on my tail much closer than that car being towed for much longer distances. Police see them all the time and they don't get pulled over.
This brings to mind an interesting experiment: If you could find an old water-wheel used for industrial purposes, then attach a transmission system with geared rollers to drive the wheels, you would have a rudimentary hydroelectric plant. I am sure there are situations where water power and machinery are available (Amish country?), but the electrical infrastructure does not exist to charge a vehicle. Simply turning the wheels on the Tesla would provide energy that could be used for transportation or to power a home. Maybe this is a good application for a wrecked Tesla automobile? There is lots of potential in this. Thanks for the awesome channel and have a great day!
Hah, I thought of the same thing. I was thinking "hmm, what if the show The Walking Dead happened after Teslas were abundant...?" Or just pull up to a dock, park and secure the car, and recharge with the wheels on rollers spun by a river.
The new F-150 Lightning has a very similar mindset about this, as Ford says it can give energy to an average american house for 2 or 3 days, or be used as an energy storage for other electrical things to be used
Yeah. Electric motors and generators are almost the same. In tesla, the difference is ever smaller. Maybe in a future you can have teslas doubling as generators for wind and water power.
just use an electric motor then, it makes no sense to use a car
Would that not artificially add mileage to the car?? Also tyre wear would slightly increase?
Man Facebook getting crazy of your video on Tesla Drag charging..👌👌👏🏻👏🏻
Thank you for doing this video. I have thought about this myself and you have answered my question
Guy in Poland did this with a truck (~18 tonne) a few years ago, the Tesla regen was limiting charge at some ~60kW.
Quick comment from the other side of the Atlantic : using a rope like yours is not allowed to towed vehicule, in Europe we need to use a fixed metallic bar designed for that purpose. Awesome video, pretty much amazing ;)
What!? I got a 5 ton two strap from AA :|
I don't see any mention of this here.

Absolutely beautiful experiment
Try it with two teslas. Whe pulling one is out of juice, swap it and let that other one pull. Repeat untill both are out of juice.
Dude, you just solved free energy!
Law of Thermodynamics would like to have a word with you.
@Benito unfortunately, no. The EMD DDA40X dual engine locomotive had a mode where one set of axles would be providing forward attractive effort, and the other set of axles would be dynamic braking into a resistor bank in order to test the locomotive. Even if that energy is going into a huge battery, there would be losses..

5 mpg - 47 l/100km woooooooowwww!!!
The AMG probably gets like 6 mpg normally
LOL.. nah 18 city 23 highways
@@WarpedPerception that actually makes sense, if it's charging the Tesla at 4 miles per mile, and driving itself, it should burn 5 times as much fuel, which it does almost exactly. EDIT: it's also pulling the Tesla, so I guess it's 6x the normal energy usage. Probably is a bit more efficient under the higher load.
Thats a great point, definitely very interesting to think about the numbers and how the energy is being converted
or the measure for those from Brazil: 2,1 Km/L 😳
This is actually really good to know if you are stuck, one of your buddies can tow you while you refill
Life is an Adventure
Thank You for this Video
You are a pioneer for figuring this out, bet there will be a pick up/drop off service soon where they keep wheels on ground for regen while transporting for maximum time efficiency. Plus also just great for when ur stranded. Never ever even think about driving of below 5% save that for getting in and out hooking up ur strap
To be completely honest, if all the cars are going to be Electric in the near future, people are absolutely going to come up with clever ways to recharge these cars quickly.
This will never, ever happen. I can't believe the comments on this video.
@@randomname4726 please leave a comment with a better solution than mine
He was talking about the straightpipes who collaborated with engineering explained to tow the car around a track
You need more views! That was great!
So you're in your Tesla on a highway and notice a low battery condition on the dash. As you accelerate up to the big truck, you deploy your telescoping magnet to the trucks steel ram bar at the tail. Once you've got what you need, hit the retract button and signal left to pass!😃
Cool video!
Tesla supercharging mobile units.
Cool demo. Good thing it's not necessary to go 70 mph to get peak Regen.
I was gonna say, once it hits peak regen, it’s unnecessary to go any faster with the tow vehicle.
What MPH is peak Regen?
@@NathanaelNaused it looked like his Regen kilowatts peaked at about 55 MPH or so.
To my mind this makes a good case for hybrids.
That's what I'd do, a diesel generator in tow working like the tender for a steam locomotive! 😂
My favorite part was you doing all the math for that in your head.. you've gotten a new fan sir
I would do it with a tow bar instead of a strap this way you have more control and you won't have to be in the car being towed, or pushed with tires strapped to the front bumper of the tower this way the tower and the towee aren't tethered.
With a Tesla you have to be inside the car unless you climb out the window even then i wouldn't try it, the car had a mind of its own
In order for regen to work, the car has to be in Drive mode, which I think is only possible with someone sitting in the driver’s seat.
If you can add a force sensor in the strap, a simple weight sensor will do it; and record how much force the strap experiences it would tell us the efficiency from wheel to battery the Telsa has, using power = force x speed
A coastdown test with full regen may roughly get you the force value too.
That's pretty awesome great test
That insane! Thanks for the huge tip!
We used to coast our cars about 15 miles down from a ski resort all the way to town and if you got a greenlight you could go another 10 miles all the way out to the dry lake in the desert. If I had a Tesla wow Savings!
rolling is more efficient than regen braking, so a tesla would be less efficient on hills
@@Blox117 Please think about what you just said.
@@Blox117You do a combination of rolling and regen braking to maintain the desired speed. If you were just free rolling the entire way, you’d probably built up way too much speed. So instead the extra energy goes into regen.
I love his content
Thank you.
Yes it is truly amazing that you all didn't get a ticket, rear end the lead vehicle, did a double spin out and avoided some catastrophe! But maybe the camera survived and you edited out those items from your, um video. I'll give you the credit though and say that this is a very entertaining video!
Lol, nah you must be vigilant and pay close attention, plan things out well and plan ahead when doing these sorts of things. Nah the car is still perfect but it did break down shortly after for another reason. Thanks!
I had no idea the regen picked up so much power! This is awesome
In Wisconsin it's illegal to tow a vehicle with a strap or chain, so that's a bit of an issue for this here.
Can you use a rigid bar? That'd work as well.
@@simontist where you gonna hook this ridged bar?
Is that a real thing? It's legal in the UK, except motorways (70MPH Highways)
@@ryanmalin it's a real thing, it attaches the towing eye on each car. Stops the cars bumping into each other I guess.
It's illegal here in Arizona too.
Now I need Garage 54 to charge a Tesla by connecting one of the axles to a Lada, assuming it could even deliver 65kW
Haven't seen G54 for ages. His 3 engined Lada might suffice, or blow up trying. Could even use his concrete tyres lol.
the largest engine produced could make just under 65kw, so... no
@@lulzyboy I suspect that the regen effect decreases at lower wheel speed. So likely the Lada would just not be able to rev beyond the point where the regen is able to consume all of the power produced at that RPM.
You should get a nobel prize for crazy ideas!
😊 thanks !
Internal combustion AMG and Electric Model S working together. That's beautiful.
With losses etc you were pumping about 100-120hp into the Tesla. Nice.
Cool video. Is it mandatory in the US to have hazard lights on while towing/ being towed?
absolutely
Bag that battery power! Listen to that E55 sound! Fantastic!
well done!!! very good content.
Most torque converters lock once you reach 40mph. Cool test!
You are absolutely right !
Not when you are towing. That's why you need to add transmission coolers to vehicles without a towing package
I’d be interested in seeing a Tesla tow another Tesla. Start with one car at 100% battery and the other 10-15% then see regen can keep both running. I know range will be reduced while towing but it would be an interesting test.
It won’t be able to do it indefinitely because of energy losses like friction and heat, but it would still be a cool experiment.
Won't work. You will just keep losing range due to friction and efficiency losses.
I think the Tesla doing the towing will break. Too much weight.
@@randomname4726 also: there's a reason why a car uses 200Wh/km. Or 20kWh/100km (or 20kWh/60 miles). That's because moving a car costs energy. towing another car and roulating it will make it worse, since you have more conversion losses.
Great video! Thanks!
This is so great! This would be a neat idea for a road trip!☝🏾🤩
So... you made your Tesla a hybrid. Well, if you ever need, I can come drive the e55 part of it where ever.
that was super charged content! Thanks so much for proving this! Its amazing for it to be 65,000 watts but thats watt i expected!
Thanks! I was very surprised myself because I had read everywhere on reddit that it would reduce the amount of charging once the battery got to about 30%, a lot of people are also saying that the car would start on fire.
Hands down im amazed. I didnt think the bms would allow a constant regen like that. Teslas' the bomb.
This idea could definitely develop into something very interesting in the future
Dude! Where’d you get those sunglasses? I need to get me some
They look similar to the Oakley "Batwolf" style.
At that rate Id plug in every device just for the giggles
@Warped Perception Just an idea.. Maybe find and mod a used RAT off a 737 or other aircraft? If it can serve as back up for a planes hydraulics why not charge up the tesla battery too 😀
@@danaleks5810 You are correct
@@danaleks5810 Would you like chip in anything else id be glad to that here 😉
Really interesting great content for sure!!
Really proud of that Merc.
This made me wonder if it would be possible building a dyno type charging station powered by a flowing river.
I thought about an overshot water wheel driving rollers. I am just wondering what wheels the regenerative braking is active on, and can it be charged with two of the wheels on the rollers with the other on solid ground, or do you need rollers for all 4 wheels?
@@TimpBizkit If it's a tri motor model then it would make sense spinning all 4.
If you have that much water flow use a turbine generator and power everything, not just the car!
Yes, it's called a hydro power plant.
@@hhjones9393 I'm thinking somewhere out and about. Another interesting idea would be this giant underwater propeller that you can park by a river and throw it in the river. It has a generator connected to it that transfers power to your charge port. I saw someone make a phone charger this way, though a car would be a bit of a challenge unless you have all day to sit by the river.

Thank you. I'm always looking for solutions
Great experiment!
We rented a model S P85D a few weeks ago. It was a blast!
I think that's how they charge their cars in Russia lmao
When you buy a Tesla remember to buy the E55 Amg
Tesla for city driving and virtue signaling. E55 AMG for road trips.
@@CynicalBastard511 Sounds like the E55 AMG is how you signal virtue
Great video!!
