Hi
Great content not real easy understand sparadic English
😂 we soe tex nology
Sens. Me. Information. Cost. Els tri we. Stats. Els tri we k. Car
One peddle driving takes about 5 minutes to adjust to. My 16 year old son who now has his learners permit has no problem going back and forth between an ice vehicle and a Tesla, nor do I
While I already knew most of this, it was still nice to play in the background while doing housework.
Exactly
same 😅
There should not be two potentiometers on the fuel pedal. There should be three potentiometers. That way the computer can determine which potentiometer is not properly working and take only the information from the other two potentiometers, but send a signal to the owner to visit the repair shop as soon as possible so that all potentiometers can be working.
😊
How do you think it is done ?
This is the only video that I was searching last 4-5 days and finally I got it.
Simple and Easy to understand
Thanks 👍 my friend 🙏
Thank you! What a nice thing to say. We are so grateful to have a passionate learner like you as a part of the student community.
yes I enjoyed this video very much also :)
All cars have a wiring harness the cool thing is Tesla is moving to a 48v system for accessories and ditching the 12v system that has been used for over a century. Now with 48v architecture the wires used can be tiny reducing the weight a boatload and is much more efficient.
Resistance is proportional to cross section area and current. Power is current times voltage. So for same power delivery, 12 to 48 volts is 4 times the voltage so current can be one quarter of what it was, so for same resistance and same power loss we could use a quarter the cross section area of wire that would be half the thickness. But for thebsane length, we need only use onevquatlrter the weight of wire. Wire is coper and costs based on weight so one quarter thevwire cost.
Not quite a boat load but close.
Although, charging times are continuing to decrease, the perception of charging versus gasoline needs to be changed. The average person drives roughly 40miles a day. Every night the EV can be charged at a much reduced cost. Most people don’t have gas pumps at home. People also tend to forget that gas pumps don’t work when the grid is down. Battery storage and solar/wind can keep the storage systems charged and available regardless of the grid. In other words, we can create electricity ourselves. Most of us can’t refine gasoline if needed. Then there’s the benefit of powering your house from the EV during an outage.
I will never understand why people keep claiming that EV's use some huge amount of electricity to charge, this is ludicrous. Take a look at your next electricity bill. It tells you how much electricity in kw you use per month. Then take into account that the average EV battery is 50kw to 75kw
The world has evolved so much. 20 or 30 years back, one would have to pass a load of different exams to be accepted to a prestigeous brick - and- mortar University, get a life time student loan just to have access to a fraction of these same information that is now less than ¢50 to access from the comfort or your pocket and/from your toilet.
If your gonna put a video together on a specific topic this is how it's done. Fantastic video 👍
Thank you! What a nice thing to say. We are so grateful to have a passionate learner like you as a part of the student community.
Thanks for given full details abou EV
I think the biggest plus is they don’t stink like a diesel car where they’re being used and that is usually around people and the worst thing is going for a walk and some stinky old diesel car or van drives by
Race cars like Indy or formula one actually increase wind resistance to force the car downward to keep it from flying off the track at high speeds
The definitive documentary on EV cars.
Nice course about EV. The company I'll work for as intern is making mobile charge for EVs. And now I understood better why this charge points are gonna be game changing
Thank you! What a nice thing to say. We are so grateful to have a passionate learner like you as a part of the student community.
Is there any intern position in ur company?... & where the company is located?
@@pitchiyathaduraimohamed84 in turkey and I'm not working at there right now it was for summer and I realized that I dont want to be an engineer I want to be a doctor. Soo as a student who finished highschool recently I study to exam again
No they're not. EVs are useless 😂
Could you provide any pdf related to this topic
The main thing behind drive by wire is the cost of production. It is way cheaper and the price can be wracked up while production cost plummets. Although, at the same time safety is being compromise - but who cares. The share holders are happy and that's what counts.
How electric vehicles work compared to gasoline/petrol powered internal combustion engines:
in los angeles, california, we pay just over five dollars for one gallon of gasoline. because of the extreme inefficiency of even the best, mass produced internal combustion engines, four dollars goes to making heat, and one dollar moves the automobile.
with an electric vehicle, if we spend five dollars on electricity, 4 dollars and 90 cents goes into moving the vehicle, and ten cents goes to making heat.
it’s interesting to consider the popularity of the transition to the efficiency of electric vehicles.
everyone loves efficiency. and when it comes to combustion, those engines are heaters first. and they move a little, comparatively.
Thank you very much, as this video was very informative. 😊
Hi Sujath, Thank you for rating us. We're glad you had a wonderful learning experience! :)
Regenerative breaking is initiated when you let off of the accelerator, not when you apply the break, that's a seperate system
elaborate briefly.interesting
Using the original Leaf as an example, when driving in D mode regeneration happens when the break pedal is pressed, where as in B mode regeneration happen once the driver takes their foot off the accelerator @@Hlutea-Hmar
Braking could be defined as slowing the car or engaging the pads on the disks in disk braked cars or engaging the shoes on the drums on drum brake cars.
Ice cars can be slowed (braked) by lifting your foot off the gas pedal, then the forward motion is slowed by forcing the motor to rotate without burning fuel. A manual and an automatic gear box means that slowing feels different. But in both cases is called engine braking.
With an EV something similar happens but now the motor being forced to rotate turns the motor into a generator and the generated electricity can be put back into the battery. The amount to regenerated electricity stored back in the battery is under software control.
As well as engine braking ice; regenerative braking EVs, conventional brakes can be applied by pressing on the brake pedal.
you did this very well
Anyone who's driven an electric car knows there’s no going back to gas. No comparison and being much more efficient is a bonus. Getting about 300 miles for just $7 of electricity
How does the heat management system heat the battery up in low temps? you mention how it cools it but not much info on heating it.
Very good video. The vast majority of charging is overnight at home or during the day at work if available. Modern public DC fast charging is mostly intended for road trips. Time to fast charge has improved and on average is 25 to 30 minutes to 80%. If people could fill up their ICE cars at home, how often would they go to a gas station unless they were going on an extended road trip?
how often? I go once a month takes 5 mins to get 500 mile range in my beautiful ICE vehicle.
yes this video had it all ❤
@@Supraboyespersonally I take 40 seconds a month to charge my car. 10 seconds to connect, 10 to disconnect. Charge twice a month, charges while I sleep.
@@marinmarinhola good for you having a charger at home 👍
@@Supraboyes people without the ability to put chargers (mainly, apartment dwellers) should just get a hybrid. An EV becomes a nightmare without it.
I have one old petrol and one old diesel fiat panda. Both have done 100,000 miles or so. The diesel does about 400 miles on one tank of fuel which equates to 60 mpg. The petrol does about 280 miles which equates to 42mpg. The diesel is a fantastic car. They both get lots of love.
you haven't been brainwashed enough
EVs are much more efficient getting about 300 miles for just $7 of electricity. Less than 10% lost as heat vs 90% heat loss in fossil cars
The placement of the battery makes it impossible to flip or roll a Tesla NSHTA and the European equivalent did their best to try and get it to flip and couldn't. Tesla's scored way higher than any other vehicle ever test on safety.
Brilliant content, thank you so much!

We hope you have an amazing experience & learn lots of exciting stuff! :)
I’m following this playlist . .
Playlist ? I want to see it, if its about EV... Can You share this TH-cam playlist link @MS Banda ?
Its more easier than my teacher teach thanks man!!👌🙏

Asombroso❤🔥
Tesla doesn't use lead acid any more, they were replaced with Li batteries over a couple of years now
@@valleyofiron125 I was referring to the lead acid batteries that all EV's have in addition to their main li battery. A few years ago Tesla switched that additional lead acid out for a small li battery.
Thanks for sharing this video with us, good education,
Glad you enjoyed it
@@SkillLync yes,i did, yesterday i had the privilege to drove my Brother Tesla from West palm Beach to Tampa and back. Anxiety disorder chipping when I had to recharge, on 3 occasions, i certainly be a testimony to your video Sir, its A little inconvenience to charge, than to refuel, however with that said, the GPS is slow, compared to Google map,on my Phone, the car is the best car i every maneuver,
超級棒~ 感謝 很大的幫助
This is amazing video
Wow this is the definative video on EVs
We hope you have an amazing experience & learn lots of exciting stuff! :)
thank you 🤞
Hi, thank you for your video. Is it possible to download your video and use it for educational purpose in France ? We would translate it. Thanks. Regards.
11:19 That’s not really true these days. Heat is not wasted, a lot of times it’s used by the cars heat pump to generate heat for the cabin. In fact some Teslas use 16 sources of what would be wasted heat for their heat pump to warm the cabin. These 16 sources of heat come from everything from the batteries to the traction motors to all sorts of other components that generate heat including the liquid cooled computer. It’s pretty impressive what Tesla has done with their heat pumps. That heat is no longer wasted, it goes into the cabin when needed of course
Very information and very impact explained
Dear Onkar, thank you for your feedback. You made our day! We look forward to continuing to serve you well :)
Li ion batteries were supposed to have no problems, then we found out they would developer dendrites when they are fully charged all the time and Tesla recommends keeping the charge between 20% and 80% for daily use and even Samsung has a setting on their phones that you can enable to stop charging at 85%
aahh! not just heat from charging to 100% i though stuff sulfate and what not at low charges, i did not know of dendrites at full charge!!!!
very comprehensive description of current state of fairytale, thanks; these hundreds of cells are still VERY punk ... and its question if lack of solid/hard infrastructure and fast push to "change everything" will not destroy entire existing industry (and we, the people) faster ... my2c
Of course there is very little CO2 in the atmosphere, see NASA, ~20% O2, ~78% N, ~0.9% Ar, & ~0.045% CO2. CO2 a rare, colourless, odourless, tasteless gas essential for humans, flora and flora. Low CO2 (< 0.02% CO2) causes poor flora growth, greenhouse plant/vegetable growers add up to 0.10% CO2 for better plant results. No CO2 causes death to humans, flora and flora. Love to have an electric car but currently they do not make sense. CO2 reduction is a total scam, we should actually add more to the atmosphere if possible. Look forward to increased electricity costs and blackouts from crazy politicians and incompetent or corrupt "scientists". A distraction from insane politician. Show us the proof!!
Hi,1 year down we have BYD charging CATL batteries 🔋 take 11mins to charge 0-80%.
Sir can u make a video on, EV Charging Using Wide Band Gap Semiconductors
It took me to complete the session almost 2 days , excellent approach by skill lync , very informative
Thank you! It's always nice to hear such kind words. It is learners like you who remind us of the reason we love doing what we do. Thank you very much!
@@SkillLync Always ❤️🤝
Transition should be complete in less than one decade
It's very amazing
We all heard about firemen needs to dig a hole to bury the ecar to stop the battery flame.
EV's are usually charged at home, plugged in just like your phone over night. Charging stations are only used for long trips and the few who own them that don't have their own home
Yes because everyone owns a home … in LaLa land 😂
@@eazydoesit276 I said "usually are" are you really that illiterate? And you don't have to own the home to charge.
On which software you done this animation, plz tell me
Best EV detailed video👌👌👌
Thank you for your feedback. You made our day! We look forward to continuing to serve you well :)
Why no mention of common aerial commutator or ground rail EVs (as in trams and trolley buses), super-condenser/capacitor EVs, or Hydrogen Cell EVs?
Because trains/trams are not BEVs which is the typical meaning of EV or electric vehicle. As there are exactly zero capacitor EVs on the market today, they're quite irrelevant for the same reason nuclear powered cars are.
Additionally, hydrogen fuel cell vehicles are definitely not EVs with 96% of hydrogen being made by fossil fuels, not renewably. Hydrogen is consumed in the process being converted to H2O vapor "exhaust" which is a greenhousegas Btw.
Like most hybrids, they can't be plugged in, forcing owners to depend on one of a couple dozen H2 stations in the entire nation making them impractical for almost everyone. Can't fill up at home either like most EVs do.

I don't want all electric.
@@SkillLync bootcamp on electric vehicle or other topic like coding
In general, very good presentation, IMO. However, at 2:23:26 where you are describing autonomous features your graphic shows a slower moving vehicle overtaking several faster moving vehicles several times. A second graphic relating to the suspension system operation also portrays inaccuracies. At 2:41:06, as you move over a speed bump, it shows the tie rod end disconnecting from the steering knuckle and the lower ball joint disconnecting from the suspension component it is supporting. The upper A frame is behaving properly. The explanation of sprung and unsprung weight(mass) was introduced correctly but it didn’t explain why it mattered - you did mention that F=MA but you didn’t connect that to unsprung weight.
800 volt architecture is not required, it simply has a couple of advantages like allowing for faster charging. If you look at electric lawn mowers, Greenworks has complete lines of tools that use different voltages like their 40v line and their 80v line. All similar tools just made with different voltages because, well, to put it simply, MARKETING!
Higher voltages propellant systems aren't for "marketing", at all. Increasing voltage reduces current, thus resistive losses. The less current that there is, the lower gauge wiring can be.
Outstanding video... subscribed
Thank you for your feedback. You made our day! We look forward to continuing to serve you well :)
Wrong, there are different levels of charging because it's better for your battery to charge slowly and superchargers near restaurants or malls typically run slower to give people more time to shop or eat. Tesla Supercharger are typically 250kw but ones near malls and restaurants are 75kw
Sit down bub
NEED MORE DAVE! 🙌 NEED MORE DAVE! 🤘
Nice course and explanation
Dear Parjany Sharma, we hope you have an amazing experience & learn lots of exciting stuff! :)
👌👌👌👌👌👌👍👍👍👍👍Excellent
Nice video ..Thanks for shearing
What software was used to create the animations?
Go look at the charger you have for anything. VoltsxAmps=Watts. Look at its input vs output. If it outputs 2 amps @ 20v DC 40 watts. It takes 1 amp @ 120v AC 120 watts to convert to a lower voltage divisible by 6 to charge. Now imagine your 800v Hyundai on a split phase 240v/480v infrastructure. To get 50 kW/h it will use 150. Right now they subsidize it and only charge what you get to sell the car. Wait till that changes.
Enjoyed this
We hope you have an amazing experience & learn lots of exciting stuff! :)
electric motor for EV is very perfect but the problem is the electric storage
OMG really, lead acid which is currently being used in ice vehicles failed often, which is why a lot of people carry jumper cables or now a days small Li battery car startes in their car. NiCads have been around since I was a child but we're terrible because they would build up a memory, in other words, if you didn't fully discharge and and fully recharge the battery from time to time the amount of charge you could get into the battery would decrease over time until the battery was unusable. I worked for a computer manufacturer in the late 80's that made laptops with NiCad and then tried to switch to NiMH to get away from NiCad because of the memory issues and NiMH was supposed to fix that problem, but like I said earlier, they would implode on the production line releasing toxic fumes.
It is December 2023 as i write. This video was made a year ago.. EV's have now been proved to be not as the propaganda of a year ago showed them. Selling figures are so low that their production in most major producing companies has now stopped.
👍👍👍👍👌👌👌👌🙏🙏🙏🙏🙏🙏🙏🙏Excellent one
There is a cost to producing hydro 1 Type of generation producing CO2 2 expense to bury U 35 for years 3 changing the environment [ landscape] for production of hydro Second cost delivering the transmission of power to from the source to car. Source of material for batteries eg 150 miles from Thunder Bay Ont is a source on Indian land Last fire from these batteries can not be put out easily Eg ship caring 500 ev cars aboard caught fire off Holland ???? New source of fuel needs to be developed Good film about EV cars.
Also, on a trip if you stop and charge every couple of hours it will only take you 10 to 15 minutes to charge which is not long enough to go to the bathroom and stretch your legs. Let alone get something to eat. You end up running out to move your car so you don't get charged idle fees.
It takes 8 days to prep, install and landscape a Tesla Supercharger location.
Ice cars have to run between certain temperatures as well. They won't run when extremely cold or hot environments because of overheating or freezing fuel and ice vehicles do not have a thermal management system
😅😅😅
The only maintenance on a Tesla is tires and wiper fluid. Oh wait, because of regen braking, you might have to replace the brakes every 200,000 to 500,000 miles
It wasn't short range and high cost, Ford's wife drove an electric vehicle and the bill on maintence for the year was one nickle
Other than charging the batteries, what rots or rust first if you don't use your EV for, say, a year?
The resale value is the first thing to rot or rust.
tell us a little bit more about the batteries... the way they been produced
Best part of the video was interior soft touch and seats upgrade
Thank you for your feedback. You made our day! We look forward to continuing to serve you well :)
This is an old video but I found it interesting however nickel cobalt and magnesium will get less as technology moves forward all ready they have the new sodium batteries in ev's and many more types of batteries. ♥
I don't think that you're going to see too many sodium ion batteries in EV's. The energy density is just too low, compared to lithium ion.
@@davidbrayshaw3529yes there still in development and there are other batteries out there looking very promising.
Chevrolet Volt is hybrid, but Chevrolet Bolt is plug-in BEV.
Good job 👏👏👏
Thank you! What a nice thing to say. We are so grateful to have a passionate learner like you as a part of the student community.
Does any one still remember those emergency kit flashlights that you have to shake to generate the power? How about having the car's suspension system to do that too?
Economic good environment
12:30
All internal combustion engines release harmful hydrocarbon gasses? What about Hydrogen fueled IC engines?
Seriously, you didn't use Tesla connector, after market connector is way bigger than than the real thing so that it makes ccs and Chademo look the same size... Really
they work from the power that is stored in its battery; AND THAT WAS PRODUCED BY BURNING FOSXEL FUEL...
Wrong again, Tesla developed an eco friendly method of mining that leaves the area the same (minus the lithium) and a new eco friendly method of refining the lithium, they already broke ground on their lithium refining plant in Texas.
16:23 Ehhhh EVs have a generally lower maintenance powertrain but their low voltage wiring and other areas of QA have been lacking. Also, an ICE will have the same range it did at 300k as it did new. BEVs will total themselves if they need a new battery
Wow!!
We hope you have an amazing experience & learn lots of exciting stuff! :)
🙏🏻🙏🏻❤️
Also, inductive charging is inefficient and expensive for large systems, not needed imo.
EV's don't have a transmission, they do have a differential. Obviously, in order to distribute power to more than one wheel a differential is required. Most Tesla's are all wheel drive with 2 or 3 electric motors
@@cavramau sorry, I meant to say diiferential not gearbox. As for some EV's using a two speed transmission, due to the way an electric motor functions, only EV manufacturers that DON'T know how to build an EV use one. They are unnecessary and only add more parts that can break and need to be serviced.
@@cavramau Oh, and it was rude and uncalled for to suggest that I "learn about differentials and gearboxes" By definition a gearbox is any box of gears, that would apply to a differential as well as a transmission. Yes, I could have said differential which would have further defined it so I edited it and used the more narrow defining word. But that does not give you the right to be so condescending, especially when I was correct in my original statement.
@@TwilightKid ok.
Once again, Tesla has designed cobalt free batteries, but cobalt is still used for refining gasoline
Oh my …. Have you seen what lithium mining does to surrounding water ? Instead of living in this La La land of everything good … research
@@eazydoesit276 A troll has to troll. I see you only selected about 3 of my comments to reply to out of the huge number I made on this video to spit stupid replies to but you really should do some research first. As for this insipid reply, had you done some research you would know that Musk invented a.new method of mining lithium that leaves the area EXACTLY as it was before the mining began, sans the lithium of course.
Are you kidding me? Cobalt free battery chemistries have been around for decades, longer than Tesla has even existed. Both BYD and CATL use this chemistry while Tesla is flogging a dead horse by using NCM chemistry in the 4680 cell.
I love how these videos just skip the INPUTS required to created an EV vs ICE cars .. 5x the inputs are needed and many of the rare earths cannot be sourced locally (USA wise) .. and sourcing these inputs require ALOT of fossils fuels, a good book that breaks this down is Vaclav Smils "How the World Really Works"
Interesting you had a graphic with a Tesla and flames coming out of the front of the vehicle. You also conviently left out the Tesla that was driven off a cliff and everyone survived.
The electric starter that made the difference, gas was hard to get, they used other things as fuel and they were terrible to drive
41:50 …a diesel motor can be started without batteries…
Tesla doesn't choose, they design and manufacture their own state of the art motors
