Electric cars are making big waves in the automobile world. These noise-free, pollution-free and high-performance vehicles are expected to make their I.C. engine counterparts obsolete by 2025. This video will unveil the hidden technologies behind the Tesla Model S, which recently became the world’s fastest accelerating car. We will see how electric cars have achieved superior performance by analyzing the technology behind the induction motor, inverter, lithium ion battery power source, regenerative braking and above all, the synchronized vehicle mechanism, in a logical, step-by-step manner. The working and features of Tesla car is explained here with help of animation.

Honestly, the regenerative breaking system is one of the biggest assets of ECs (Electric Cars), which gives it a high energy preservation and efficiency. In my opinion this tech also works really well in hybrids, which gives them the best of both worlds. I said it before, and say it again, that until they develop an energy pack (aka battery, capacitor, or fusion) which gives the same or better range as ICE cars (Internal Combustion Engine) and deploy charging stations at every gas station, ECs are just a toy for now. ;)
Ok ,, the motor acts as a generator under regenerative braking conditions and converts kinetic enenrgy in to electric and sends it to the battery. What type of electricity it creats ?? AC or DC ?? Does it send the energy directly to the battery or to the inverter first and to the battery afterwards??
Guys please help me if you know
I have a solution to slow charging electric cars... Simply rent the Batteries. Like a service provider. You pull up to the "gas station" swap a universal fit battery for a fully charged one and you are done. Some bigger cars might need 2 or 4 batteries. The "gas station" will charge the batteries and keep them in top condition. None of the batteries are yours, they all belong to the "gas station" - You simply pay a membership for the amount of battery swaps you use. You are welcome
they always use these kinds of motors, but inverted technology and the much improved battery technology has brought them back from the dead, using super charging a battery can go from 0-80% in 40 minutes.
i dont own one either but i would call these advocates Tesla fanboys, they seam to smugly act like electric cars are ready to replace all ICEs but realistically it will take another 20-40 years and several billion or several hundred billion dollars of R&D and infrastructure to completely make ICEs obsolete for everyone.
John Electric cars are great today and for many people can replace some or all of their driving with gas vehicles. But, it's far from perfect and some people are tremendous advocates, but don't own one. I own and advocate, but try to tell people the whole truth. For example the charging stations are hit or miss. Tesla seems to do the best job, but they are selling 100s of thousands of cars all of sudden and their stations out in California anyway are often full. On other networks, "fast charging" is rare and can be more expensive than gas. The smartphone aps like "plugshare" are free, why not download one and see what charging options are close to you and on routs you use often.
First thanks everyone. I'm asking because I am thinking for my commute to and from work each day. Its about 125 miles round trip. As far as my long trips its a little under 1000 miles one way. Driving 2017 ram 2500 Cummins loaded down. Camper family etcetera. Running 80 mph or so. I drive at night so everyone is asleep. But there are times where we make that trip in car too vw passat. Same as above driving.
+Josh Carlisle charging from almost dead is the fastest way to charge but not recommended due to how much it shortens the battery life "They take about 20 minutes to charge to 50%, 40 minutes to charge to 80%, and 75 minutes to 100%" 12 hour trip Is likely to be a 16 hour trip. Not so bad if you use the charging time to eat and rest.
A 14 hour drive in 12 hours does sound a little impossible. :)
I think you are asking if it's possible to make a trip that takes most people 14 hours, but you 12, in an electric car in 12 hours. And the answer is no. Recharging the car, even a TESLA at a TESLA Supercharger is not as fast as filling a car with gas. I don't know how far you 14/12 hour trip is, what car you driving, or how many places there are to charge on your existing route. But I'd guess that you'd add 2-6 hours to the trip.
Pollution free? What a TOTALLY moronic statement. Where does the power come from to charge these cars? And what happens with the totally toxic batteries? Electric cars are a good idea, but TELL THE TRUTH...!!! They are as much or more polluting as internal combustion engine cars.
+Dash - hope NO ONE puts any stock in what you say. Again, as before, you just post crap you find in the internet. Well... this EE doesn't give any credence in what a basement dwelling bottom feeder says. That officially gives you the status of TROLL.
One more thing... "explosive properties" is a scare-tactic. We can and have demonstrated massive use of Li-ion with minimal "explosions". I hope people don't put too much into what you say because it's a bunch of baseless conclusions and you haven't provided any evidence.
I don't think it's "trouble" to do research (and if you do, then I see there's no point in discussing this with you). Yes, they are manufactured different now and the processes are better. We can reuse the silicone byproducts now as an example reducing waste. Kinda disappointed that you didn't want to actually discuss this but I guess it's youtube so whatever.
+Dash - you went to all the trouble just to be wrong. Nothing has change. Are you saying that Lith-ion batteries do not contain the same thing they have always contained and are manufactured different? Likewise for solar panels? Keep drinking that grape kool-aid. You can see in table one... you are missing your brain.
Thanks for your response. Unfortunately, your information is outdated. While it's true that there are still hazardous wastes coming from the production and disposal of solar panels, the processes are continually improved - it's a new technology after all. As we start to increase production and economies of scale are improved, costs and damage to the environment decrease.
Here is a source that includes waste in the total lifecycle: (http://www.world-nuclear.org/uploadedFiles/org/WNA/Publications/Working_Group_Reports/comparison_of_lifecycle.pdf).
You can see in table 2 that while the high ranges are indeed comparable as you stated, it is no longer the norm as we've learned and adapted our processes (I say we but I mean the engineers and all those behind the scenes people). As you can see in the mean CO2 emissions are less than 10% of what coal and gas are. Continue to research (and thanks for having some background knowledge before speaking) and hopefully we can see a good outcome for humanity and not just try to win a debate.
Learn Engineering should do a video on the Formula 1 race car.... and then compare it to this high dollor piece of garbage... Its ok though... The testla "looks" cool right? Nikola Testla would be turning over in his grave if he knew his name was being used for this "Thomas Edison" type trickery
Formula 1 race cars are the true example of how this technology should be implemented. The F1 race car is set up to collect and reuse lost energy that is usually wasted from the brakes in the form of heat.. converting the heat into electric energy that is used to recharge the battery for the electric "assist" motor as well as assisting the turbo in spooling up and assisting the combustion engine. Why Doesn't this Testla car have the components that enable it to be mostly self sustained by recharging its own battery like the Formula 1 race cars... Testla is just a bunch of expensive hipe... making it dependent on the "Battery companies" and its inefficient old tech batterys. Testla cars were disigned not to be efficient... just another way to "dupe" people in having to buy parts.
If someone is thinking about buying a Testla... I suggest demanding answers from the dealership.. They are not going to have an answer.... they just make things "look and sound" cool... nothing but a fake ass company
+J Oakley well then make your own god dam self sustaining car you fucking retard, what the fuck do you mean i have not walked the path, will you thrown on the ground when you were a kid and that's how you experience perpetual motion? I didn't get this from a book, I just critically though about the environment I live and mentally tracked where the energy was coming from. You watched some good damn YouTube videos and couldn't look farther than your own shoes because you are a short sighted retard who believes perpetual motion machines actually work, and no amount of watching YouTube videos will make you any smarter then the brain dead audience they where made for, go learn some basic physics so you stop being a waste on this planet. Seriously you didn't even know the sun had a affect on warts physically environment, even a fucking grade schooler know about the water cycle. but then again you are a fucking retard, what other brain dead examples do you have so I can use 9th grade physics to demolish it, cant even do a KE calculations and think you have it figured out, god damn I hate smug retards.
I mean, what part of what I said do you disagree with? Lemme get this straight... You don't think that (other than from a nuclear power cell) it is possible to have a self sustaining electric car with our current technology? If that is so then you are a fucking moron... I can't put it any more simple.... If you can't grasp it,,,,, well then it sucks to be you buddy..... Im outta here
its common sense. Of course all this potential energy will cease to exist when the earth stops spinning. Don't you see... Human beings are perpetual motion machines.
Look how much output comes from a human being compared to the input of food. All this high tech we see everyday is because we had energy left over from what we require to sustain ourselves. Can you see the math yet? Its all around us. Why the fuck can't you see it. This physical World IS manifest mathematics.. All that shit you describe as well as everything I describe COMES from the same place... THIS PHYSICAL WORLD... First question for you? Do you have any actual physical experience putting into practice the words you speak? ... You prolly won't even get this far, EGO has stopped you... but good luck anyway.
One thing I don't understand, if the RMF speed exceeds the rotor speed, the batteries are still providing power to have a Rotor speed in the first place right? But if the batteries are used to create the magnetic field (that turns slower than the RMF speed, but still) then how can the batteries GAIN energy... I know it works, it just conceptually doesn't make sense...
When driving a car with combustion engine @ speed X and use sudden brake the hole clutch and gear box acting as dapper of the fly wheel to the pistons. Which parts of the electric car act as dapper so that the electric motor not overloaded and be hot @ time be damaged effect it’s life?!
Quiet, No more gas stations, home charging, excellent acceleration, automatic satellite upgrades, large screen, No central bump on the floor, Range 290 miles, free charging all over United States, Courteous service.
Unless we stand up, the day is coming when the government will tell you "electric car performance is superior to petrol powered car performance", and if you dare to disagree, your family and friends will (quietly) wonder forever about your mysterious disappearance.
The 'electric car' agenda is to help people get used to having their choices made for them by bureaucrats and a self appointed all powerful ruling council. Goodbye usa constitution, bill of rights and freedom.
The video description says electric cars are "pollution free". Any thinking person knows the energy, chemicals and materials it takes to make the parts, assemble the electric car and power the battery chargers are quite far from being pollution free. But left-wingers (communists) must tell lies constantly to move their insane agenda forward.
+Mike Day the model 3 at 35k dollars might be available next year once production catches up but it's not a hipster car but definitely for the upper middle class, it has a 315 mile range (on extended range version) wich is not bad since my jeep also has similar range but for me it would be 5x cheaper to refuel where I live then my jeep and is less hands on for maintenance. Only ICE on the road in 70 years would be heavily taxed and regulated classic cars. Also solid state batteries are pretty safe batteries much safer then the cells in a tesla so those might make their way into EVs in 6 years.
Miguel lopez The model 3 is showing amazing acceleration numbers. Many new car designs have a period of sorting out problems, and these cars seem to have plenty. At the moment they are expensive hipster cars for short distances. As long as the government is not forcing people to go electric I'm okay sharing the road with them. Freedom to choose is paramount. Rich people will never give up their classic ICE cars. Also the huge Tesla batteries can never be made safe enough.
Tesla is an American company that is very capitalistic in nature and is inspiring other companies to compete in this new electric market, lifetime pollution from an EV is equal or less of an ICE depending on power plants.
Yes, but these cars become epensive in the winter because you need more electrisity to heat the car, Plus it is complicated and full of electronics so it brakes easaly and is more exspensive to repair, electric pawer is usualy olso fearly exspensive in most countries so these cars are expensive
About 50 miles per dollar of electricity and electric cars break down far less often than gasoline cars because fewer moving parts. Electric motors are rated at 1 million miles and no transmission to break. First scheduled maintenance in 4 years and brake pads can last 100K plus miles thanks to regen braking. Basically just windshield wiper fluid and tires for maintenance. No oil and filter changes, air filter, brake pads, transmission fluid, fan belts, exhaust, power steering fluid, etc.
I really dislike that coal is powering the electricity of modern civilization. If we switched to nuclear power I'd be comfortable going all electric but for now hybrids and motorcycles are where my heart lies!
I'm all for electric cars, it leaves more gas for me! ;^) Telling OPEC, Russia et al just WHERE to stick their oil barrels would make my day. I would LOVE to learn more about them, but I could not listen to the narrator. I find his uptalking annoying as Hell. It must be mentioned that, if my "petrol" car runs out of fuel in the middle of nowhere, (after 600kms) I can refill the tank with gas I have brought with me. Is there room in a Tesla for a tank of electrons? Also, at this point in time, it is much easier to have a IC engine serviced in an emergency. That will change of course, but the current electric cars still have drawbacks for those living outside of major urban centers.
The batteries are not the solution for replacing the fossil fuel !!....simply because the whole story is based on lies ...First of all the Tesla batteries not gonna last more than 13 years(two mandates of President Obama) and those are best in the world,..and are so expensive that really cannot replace ever the fossil fuels. So instead of dreaming, we should take a look what they try to hide behind batteries ....It is very simple, what you 're burning in Gasoline is Hydrogen but Water have more Hydrogen than the Gasoline and the rest of it is Oxygen .....https://www.youtube.com/channel/UCbh5a1_NgGRpNNtgOP6l_4Q?view_as=public
+Blue fuel Systems H2o gas I never went to wikipedia, smart people do this one thing called "research" it really helps make educated conclusions about things, I've done a lot of research before this argument so I dont say something stupid like lithium ion batteries have a life span of 13 years then run away when it turns out the other person knows more about batteries then I do, hell do you even know what an anode and cathode are?
uel Bishop putting words in my mouth not gonna make you popular and your degree not gonna help eny battery last longer than 13 years... I never asked you a question because you are rong, and copying statements from Wikipedia will not hide the fact that you are.... Paranoia
But the materials used to make the batteries come from china where the miners are not treated well, and they have to burn loads of stuff aswell so dont think you need a "environmentaly friendly" electric car
Nuclear is about 20% of the grid, and yes they pollute more then 100x deisel cars wich would generate 17.340 Megawats of electricity, a nuclear power plant however generates 3,400 megawats ot about 200X more energy then 100 deisel cars, so per kilowatt a nuclear powerplant release 5% of the pollution of a 200HP deisel engine. Also the pollution from a nuclear power plant doesn't come from running it it comes from building the structure and transporting materials to it.
i really thankfull to all participant,who involve in team of making this video.its really good to gain some basic and important knowledde about electric car .I m looking forward for more this kind of video.
Yes you are right. Charging outpost can be errected every mile or so. Hydrogen can be produced at atmospheric pressure using lower power loads as well which is even more less energy intesifying than currently undergoing 2step metal oxide process. Even considering how ceratin major percentages of electricity are generated(Fossils 61%, Hydro 20%) today and so if there were to be a choice among the option Battery or Hyrogen for the next long run. Which among would you think will be peoples choice? Not just looking at automotive but power generators as well. Batteries store energy but Hydrogen helps generating it.
+Pratosh Santosh yes yes I know that hydrogen has far far more energy per kg then a battery, but the economics and logistics have favored battery power for cars, cheeper fuel, abundant charge points (240V 48Amp recepticals are more common then gas stations) and a lower net energy lifetime usage make up for lower range, expensive batteries, and longer fuelling time.
Sure batteries are 99% efficient. But i also wanted you to know that there's a method called 2-step metal oxide to commercialise Hydrogen manufacturing on large scale. You are right it is energy intensive but look it this way. Every(macro) system we consider in science behaves like a spring. Everything vibrates, stretch, contract. Fuels are like compressed irreversibe spring. If in a spring made of mild steel and of the same pitch and mean coil radii, then batteries are 1cm long whereas the Hydrogen are 57cm long. Then the more you compress more energy we accumulate. Considering energies per kg.
hydrogen solves the range problem and car emission problems but runs into the issue of it being very energy intensive to manufacture the hydrogen, more expensive then electricity for refueling and having lower efficiency then a battery which means overall an EV will use less energy to move one mile then a hydrogen powered car, the models 3 gets 354 km (3,549 lb) from 50kwh battery and the extended range version gets 506km 3,838 lbs from a 75Kwh battery, something like the Hyundai NEXO gets 800km with 156 liter fuel capacity.
Correct me if im wrong. A tesla nearly weighs 2 metric ton which is a family sedan with the torque of a race car and a normal family sedan weighs 1.6 tons. Full battery range of (400-430)km against (900-1100)km of full tank. They are pollutable substances though, but dont you think that another gas could fit in? Hydrogen?
+E.G Drift King this means that the the generation of electricity from the Tesla's motor is something that has been around for a 100 years, and other electric cars have had this ability to regenerate Kinetic energy.
The electricity is generated by coil windings and magnets attached to the wheel, when the you let go of the "gas" peddle the magnets engage, the spinning tires cause a temporary magnetic field to form flowing in the opposite direcrion of the wheels, this is what does the braking, but simce the magnet is still moving it will also move electrons in the copper winding generating electricity.
This concept is the basses of almost all electeical generation in the world from nuclear to coal, and hydro dams.
Both of you are very ignorant on the subject.
