Can you use an Alternator to Charge your electric car?

- The biggest problem most people have with electric vehicles is the range, and the charge time that go with it. Range anxiety is a real thing, but what if you could charge the batteries while driving. Now some companies already have range extenders, which are small ICE engines that generate power while you drive, which then charges the batteries and extends your range.
But you see a range extender still needs fuel in order for it to run. So what if there was another option. An alternator.
Firstly Lets talk about what an alternator Is and how it works.
So in your average ice car, you have tons of electronics, from your radio, to headlights, tons of sensors, the AC, the list goes on and on. And all of these systems use power. Now your car is fitted with a battery, but your car’s battery regularly burns through a lot of power and that’s where the alternator comes in. After your engine’s running, the alternator recharges the battery back to full strength, plus while the engine is running the alternator takes over all the load from your electronics, and powers everything.
But how?
The alternator works by turning mechanical energy into electrical energy. You see when your engine is running its spins a pulley, this pulley is connected to the alternator via a belt. This then turns the Alternators rotor shaft, which spins a set of magnets around a coil. These spinning magnets generate alternating current (AC) around the coil, which is then channeled to the alternator's rectifier. The rectifier converts that AC power into DC power, which activates your car's electrical systems.
And that’s where the question comes in, could you not connect an alternator to a moving part of an ev in order to extend the range of the car?
Well lets find out.

How about a small gas generator built into the car to charge it?
The author says that the alternator would not work if wheel-driven but I disagree... if a pulley with belt was attached to the drive shaft that connects the motor to the wheels then it would indeed provide at least 15 volts of charge per wheel. Have 4 alternators on each EV and that's 60 volts of charge with virtually no pull on the EV's battery to power each drive wheel, while the other wheels are turning anyways without a motor attached.
If you use a gear ratio that uses little kinetic energy ti turn and a high ratio for the alternator, in theory, you could extend range quite a bit. Because if you are replenishing the energy you’re using as you use it, yeah it’ll be a net loss, but way less than the friction required to turn the wheels just by themselves and when you’re coasting downhill, it’ll recharge the battery with just gravity doing the work. I want to try it out and see if it’s a viable option
The reason you can't have alternators on electric vehicles is because unlimited range would mean no tax harvest for your government
no the extra load on the motor will make it draw more power
Actually, it’s called mileage tax They just see how many miles have went on your car every so often and charge you on that so it wouldn’t really matter if your car could charge itself or not.
@@hugodecotignie3834 not by much have you ever spun a alternator it really doesn’t drag all that much. There’s more drag being done by the road then there is from the alternator. The real problem was with how much the alternator can put out compared to how much the engine is consuming.
@@thepropview9517 explain
@@thepropview9517there is a alternator that puts out 10 kWh which is over the amount to charge a. 50kwh BYD car which is 7.2kwh. I really have been thinking about this all day.. this has to be possible and should be easy to do on the free sprung wheels that aren’t actually driven from the electric motor. Like the rear wheels of a fwd car. Even if this doesn’t make unlimited power, I don’t see why it wouldn’t at least extend the range
Physics left the chat
Pretty much, imagine thinking there is free energy out there and the car companies with millions of hours of R&D couldn't figure out how to harness that energy but 🤡s in the youtube comment section can. No wonder the aliens dont want to come and visit us, 99.9% of the population is ret@rded.
It will not increase your range. 😆
More weight
More wind interference
More gas used
More resistance on tire
Needs new BMS
CREATING POWER IS ONE THING NOW TO USE IT OR STORE IT REQUIRES A NEW BMS...
YOU CAN NEVER EXTRACT MORE POWER THAN PUT IN PLUS AS MENTIONED B4... Prius tires keep spinning internally when brake is applied. That recycled kinetic energy charges the battery. Adding an alternator would be 2 steps forward one step back...
Why not just add a extra battery and a switch. While you are driving it can charge the extra battery. When that battery gets low just flip the switch
Weight😂
@@ChrisVSCars True that true that 🤣🤣Should have thought about that 🤣🤣
Ying yang
Most likely it would decrease the range as the electric motors have to use more power to overcome the braking action of the alternator. That's why regenerative braking was added into EVs, to extend the range by using an electric motor's inherent braking ability when it works as a generator. Instead of wasting the kinetic energy as heat with brake pads and discs, the motors can use it send electricity back into the battery bank while slowing the car.
Well, but my idea now is to create use the rotational force of the shaft on its way to wheel..where it acts as an amature then it is surrounded by a coil
No free lunches in this world when it comes to energy. What you are describing is already used to recover some energy through regenerative braking.
Ever heard of regenerative braking? All EVs already have an alternator, it's the same motor that turns the wheels. It arrests power to brake the vehicle when you aren't having your foot on the gas!
The alternator and battery only as backup because the tesla motor is permanent magnet arrange at an angle that it need no generator at all but whenagnet fail that battery drive the back up
But the drive shaft is spinning anyway?
Exactly! And so are the non-motor driven wheels!
2:27 I was getting worried that someone actually thought this would work.
Yes it will work, Altenator it is the same function like Electricity, Electricity in like wind Electrical generator, that get the Energy by just rotating,the same as 💦 water electricity the Energy comes by rotating a motor just like Alternator,
The technology exists, it’s just not applied here. Why would any company want to sell you something that you’ll never have to come back to them again for?
@@Isaac-Gbornor- The wind is the source of the energy, where is the wind coming from? If you can create wind from nothing, then your theory makes sense.
@@q6906 comeback to them for what? Charging?
@@StriderVM I’m general. Planned obsolescence. Companies don’t want you to have a car that gets 100mpg or to have a car with parts that don’t need to be replaced
No you can not. End of story.
The saddest thing is that this isn’t an April fools video
Why is it sad😂
@@ChrisVSCars because obviously an alternator would be inefficient. You spent 4 minutes when you could have just stated basic laws of thermodynamics. And still at the end you said it would have little effect, when in reality it would have obvious negative effect from parasitic loss.
Ohh😂 yeah, but some people don't understand that
I have a question. With scientists recently discovering nuclear fusion where there is more energy than what was started with, doesn’t that violate one of the laws of thermodynamics?
@@Mabeylater293 Well that's the point of producing electricity, produce more energy than you need to make it happen. Every type of electricity production do that.
Look at all these comments they think they are advanced electrical/mechanical engineers with hundreds of 1000 's of hours of R&D like these car companies have. Lets install a 12v alternator from a 78 chevy and mod it to charge a 300volt traction battery and install a dc to dc transformer to charge the battery, even the presenter said you cant charge/discharge the battery at the same time.. The school system has failed 99% of you all 🤡
How come they don't put solar panels?
That is where gearing come into play.😉 Gear it so the alternator turns faster than wheel shaft = more output.👍
You're just trading revs for torque. You cannot increase the power in a system and get energy for free.
So "it won't increase by that much" then that means it will increase some... seems like a win to me.. 😂
So then, why can't you have magnets bedded into the road, and as the car passes over them it would turn a onboard alternator to charge the battery? As long as the car stays in the center of the road and travels at the posted speed limit, your battery will be charged.
Hell yeah I agree 👍
The only way I think k you can is two sets of battery banks..one that's shut off while charging.. when the other battery needs charging is throwing electronically a switch disconnecting the first battery requiring the second battery to take the load..once the first battery is completely disconnected from the circuit then it can charge independently..if this is possible just a thought..
Bruh it's already a feature it's called regenerative braking.....
nope that's from reverse motion from braking, which is infrequent. alternator uses forward rotation
Bruh you literally can turn a alternator into a electric motor dum dum it's been done before therefore it's literally the same thing what you said made no sense
Regenerative braking uses existing momentum to slow the car by using the drive motor as a generator, until you're almost stopped. It does increase range, a little. Saves the brakes. They last much longer.
@ghalibbakhtiar1300 regen braking is a general term but you know hybrid cars recharge even as you accelerate? Mine does ,the screen shows it, I'm sure EVs do as well
😑😮💨
Forgetting weight for a moment, what if you had a few 48v alternators driven by a 48v DC Motor and a pair of 48V battery banks.
You have eliminated as much frictional losses as possible.
Why would several high output Alternators or even PMAC’s not generate sufficient energy to top up a depleted bank?
If the gear the alternator to reduce drag on the drive axles it would at least hive you extended range. Apply a excitation field when the vehicle is not under a sever load like sum straight aways and hills. The alternator can be incorporated into the drive assembly
Yes the Rich and powerful people don't want us to free Financially and mentally, still buy energy to run this very expensive cars , very bad
What is the car's name on the thumbnail?
A + B banks: dividing the batteries, charging half while using the other half. Automatic or manual transfer switch to charge (via alternator) the A or B side when it is down to 30%. Integrated hub/gear assemblies belt driven, to alternator, mounted in trunk and front. An alternator spins very efficiently and the additional weight is minimal. In my field of work this is very simple and can be done. But for now, ICE & Hybrid vehicles will be around for a long time as Exxon has recently invested into the Permian Basin in Texas, now consolidating its position with a $60 Billion acquisition of Pioneer Natural Resources.
The Rich and powerful people simply want to keep in Slavering us ,they never want us to be free , mentally and financially, simple
Well iPhones and many others have wireless chargers. What about a charging road or parking lot ?
Pay for the time you were in lot or road . Never have to get out the car . Maybe have a premium service highway . The highway charges you up as you drive at a certain speed or something .
I have a feeling that we are about to see a lot of futuristic sci-fi like changes coming at us .
here a idea just use a 50 Farad Capacitor or higher then power can be stored and the car wont use so much power
But sometimes 2-alternator generator to 1-generator for forward and 1-generator for reverse that is 2-generator to brought of self charging .
alternator back wheel drum tyres
Why dont just add 5th wheel under or behind the car just for this purpose? And have the 2 battery and switch between them..
I still think it is possible....now...if the driveshaft was modified at at some area so that it acts as an amature then and then enclosed by coil on its way to the wheel ..wont that solve the energy wastage concerns?
The 2,back wheel shaft alone can do that job gevin rotation to the 3Altenator easy as that ,They just don't want us to enjoy free Energy, but rather keep on sucking us mentally and financially 💸💸💸💸💸
You don't need batteries. Silmply use Troy Reed's magnetic motor.
You dont need the alternator to run the electric motor. That's for the batteries. I believe its possible to use a spinning shaft to run the alternator rpms to charge the batteries. I see this used with the diesal engines in boats. A man hooked 3 generators to the engine and would rev the rpms charging his batteries. This concept should be able to transfer to an electric motor to charge the batteries as long as you can get the generators rpm up to charge them. This is just out of the box thinking. I am not a mechanic or an engineer but seems to me it would work
The drag of the alternator even lessens the power.
That is not true IE the drag of the alternator heavier that the car or the wheels , Wrong you are on of the Guys who don't want the people to be free mentally and financially,💸💸💸💸💸😀😀😀😀
@@Isaac-Gbornor- If the drag of the alternator of the car or the wheels, then the battery would need a lot more power to make the car wheel spin.
If you are so sure, you can make it yourself right?
Someone will, if the front wheels drive the car, the rear wheels can be connected to a large generator. 3000 or even a 6000 watt generator can be turned by hand, not much would be needed to turn it. That should be way more than enough to extend range. This is already being secretly tested now. Nothing is impossible just improbable.
@@Isaac-Gbornor- Government paranoia combined with lack of physics knowledge. Poisonous.
@@benjaminhenderson1759 I wonder why you need a 10 hp motor to turn a 6kw generator if they're so easy to spin?
You need a lenz free generator meaning no drag ( back EMF ) when the motor spins. It's like the generator is not even attached to the motor or mover. Such lenz free generator is exist, design different than the regular one. It remove back EMF and reuse the back EMF. Hence, it creates no heat and positive energy to charge battery.
Put extra batteries and use alternator to charge it whle you use the other one..
4 tires with 4 generators, two batteries, one auto charging switching mechanism, and problem solved, when one battery is in use motion will do the trick and the 4 generators will charge the other battery, a mini-computer will be needed to constantly check the battery energy level to automatically switch to the one charging when the one in use is almost dead. I did the math in my head 10 years ago and I can tell you it does check out. However, it creates a hazard if the modifications to the car are not done professionally.
No, it doesn't check out, and you'd end up with less juice than without them. Unless you're talking about using a gas car and attempting to charge a spare car battery or something that's used for electronics/computer and not to propel the vehicle. Doing that increases the amount of power it takes to move the car by over 4x. Each thing mechanically attached to each tire greatly increases the amount of power required to spin that tire beyond what that tire can recover in electricity. Check out Jeremy Fielding's video showing some of the basic math.
@@HostileTakeover2 Do you have the resources to perform a test, I'll be willing to bet my life I can make this work the way I said? if you put the money down and the tools I'll show you that everything we have been taught is mostly BS.
@@HostileTakeover2 Just because you don't have the knowledge it doesn't mean is not possible. Albert is not always right.
@@rijotech True for many things, and true for Albert, but not for this. I will say the switching idea itself is great - I think some variation of it is implemented on Hybrids and EVs (they might use an equal power distribution instead, I'm not sure).
But alternators are horribly inefficient things. They're only good because they take the bit of excess power generated by combustion and convert it to something else we can use. Enter Hybrids that use that excess to charge their batteries & run the electric motor and also why they still require combustion to do so. That's also the reason EVs don't have one at all. It always comes back to that energy is lost in any transfer, that alternators require a LOT LOT more power to turn than they can give back, and that increasing the number of them only increases that disproportion.
I'm open to proof to the contrary if you can demonstrate it working as suggested in real world. And I encourage you to do so; self practical tests will always trump theory discussions. You can test this for yourself by spinning one by hand or whatever combination of motor, hand, whatever using whatever variety of gearing you like to try out. But you''ll need to be thorough in power measurements.
and if i so you i can do it then wat di kan gedoen word
So we could use a fan type device just like we used to use to cool the engine soon as your driving that fan will spin from wind like a wind turbine im not a car or engine guy but seems like that would work to me lol
I just love how everybody basically tries to disprove on a self-powering electrical car when they themselves have not taken apart an alternator or a electrical motor because electric vehicles uses the same principle as combustible engine or a diesel engine it's still uses the same principle because only the back end is needed to push the object in question in order to get from point a to point b and the front end is only used to steer unless it is a front-wheel drive or an all-wheel drive and so if you replace the front electrical motor with a specially modified alternator and just keep the electrical motor in the back then you can still use said object to get from point a to point b
please explain more? can a generator from wheels really keep the EV car powered on a highway?
100% wrong... all the wheels spin at the same speed they might be *rear wheel drive* but the wheels are still linked if you added a belt to the front and kept it separate you are now adding extra friction to only 2 wheels thus causes all kinds of separate issues basically no your idea sadly will never work sorry to break it to you... basically you are driving while holding the breaks yes you can drive while pressing the breaks but now you need more power to run the car thus all that extra power generated by your alternator is 100% useless so why even have it
Maybe someone (way more educated than me!) can help me here. Could a 10,000 watt portable generator provide enough power to run a EV? Not talking about using batteries. I kind of understand The Conservation of Power Law. But only kind of. I've looked all over and I can't find the actual electrical power required to run an EV motor. Or here's another option...use a small Generator to recharge batteries. If the generator can provide more power than the motors require would that not work?
Perpetual Motion is thermodynamically impossible.
Late comment, I know, but there is so argument to be made that you could manipulate certain theories of physics in such a way that what appears in one frame of reference to be perpetual motion is actually not perpetual motion in another frame of reference.
It's hard to spin an alternator when it's charging the battery. It would draw more current from the car than it gave.
VERY basic physics.
What if you add a wind turbine at the front of the car that makes use of the parasitic drag already caused by the car moving through the air?
Wind turbines has Altenator in them that is what generate the Electricity,all they need is to fix 2 altenstor to the 2 wheel shaft and rotate and it will charge the battery ,they simply don't want us to be free , mentally and financially
Just adding more drag, however, I have seen wind turbines along side the bus lane that gives back some energy.
Most electric cars have a set of wheels not in use, a 3000 or even a 6000 watt generator can be spun by hand a set of wheels could easily spin this generator. This is secretly being tested now. Nothing is impossible, just improbable.
It cannot work. The generator cannot be spun by hand when it has an electrical load connected to it. It will impose load upon the driven wheels and the power to drive those comes from the traction battery. There is no workaround the first law of thermodynamics.
Elimate the batteries. 1 battery to start an electric motor to run the alternator. The electric motor then is powered by the alternator, as is the concept in combustion engines. The problem is all vehicles have been designed to travel on an average of 300-400 miles no matter the size of the engine. Why is that? They have forced everyone to stop for a service of some kind.
I m not agree with you..infact if we put 1/2 battery for running the car , in the same way we can put more battery to run the Dynamo or alternator..and plus with the spinning mechanism when the car move on.. offcourse there' would be kinda hectic..but it could be done i guess..
The obvious answer is hamsters.
I see the vision 🤓
Install it to all 4 wheels and make it concealed.
Add some solar to the hood, trunk, and roof, then put a wind turbine on each corner, and add alternators to each axle. go fo overkill and see what works.
That’s the same thing I said
Very good car electric with An electric generator charges itself electrically
Its like saying wind is free and lets put a large turbine on a car haha, not accounting for the drag
If you had an alternator hooked up to each wheel and had it only engage during deceleration, it would work quite well to increase range.
Yessss like how a differential works👏🏽
Three phase AC motors are alternators while coasting or slowing down. DC motors are generators in the same situations.
They simply want to keep Slavering us mentally and financially 💸 💸💸💸💸 after nature has gevin us free Energy, lithium
Alternators have regulators to put out a constant voltage, so it could be used 24/7 not just while you slow down
@q6906 the extra energy needed to turn an alternator will negate any extra boost you might get in charging. There's no free rides in physics. Lol
if a car had like 6 altrnators it would surely recharge an ev battery by using the force of the ev motor to power the altenator.
I think your bullshitting the world, it wouldn’t take much energy to spin an alternator. But that’s free energy isn’t it. If you added 2 alternators to an electric car, that would charge batteries.
Yeah I am talking bs. Why dont you try it and prove me wrong👍🏻.
If it could be done, it would already be done. Years ago, you could put a small generator rubbing against a bicycle tire to light up the headlight. You had to downshift one or two gears,to overcome the drag, and it was only powering a small headlight.
Alternates always use more energy than they produce.
Mount the fucking wheels on the alternator. All four wheels on 4 alternators. No drag. Alot of power.
I agree with ya , if it’s gotta.drive shaft what’s to stop that from becoming a generator with magnets on the shaft and windings around it , seems like you could make a lot of electric and even step it up with an inverter 🤔
@@davescheer5038 that's even better 🤯
Yes you cant but they dont want to do it, is simple and you dont use electricity to make electricity, you use electricity to power the car and meanwhile make so extra range, but they make us do this with combustion engines that require petrol and petrol costs money so they dont do it because then they make no money
Use another em that rotates constantly when you turn the car on. Then connect an overdrive gear ratio to the alternator from that motor. Maybe this could help compensate for the loss of energy? The only downside is that you'd be running another separate motor. I think it's worth a try though.
It's not worth trying
It always takes more power to turn an alternator, than it can produce.
Brro are you south african?
Gotta over heat my lithium battery's man
They say the tech doesn't exist to make self charging cars but I don't agree, what about kinetic watches they exist so why no a car ran on kinetic energy.
Ow to get even less miles 🤣🤪
No shit Shurlock!
WRONG! There would be NO increase in range. I'd take anything this clown says with a barrel of salt.
Just take a bus
Yes u can, start new stories. Human evolution will go against all laws and make new laws.
Those are bs answers
Please share and remove your vale so that ya'll can have the eyes to r
Really see!!
What about front wheel drive electric car and add to the rear wheel (free spinning wheels) A Dual Alternators that’s used AC clutch to engage only when stability control to breaking
