How Do Electric Formula E Cars Work? - Season 2 Tech Explained

[@MrCube17]

The technology developed in this race will eventually benefit consumer cars - great stuff!

[@Atlessa]

Isn't that true with pretty much all technology for racing?

[@sinisavukic824]

...еби га...

[@BlackwatchCrazySix]

There is a good reason BMW decided to enter this one.

[@SkyOnPixel]

Except for nascar.

[@TheWindsofWonder]

I'm a fourth year electrical engineering major. I was going to towards communications until I learned more about EV technology. I've taken a class on electric machines and electro-mechanical energy conversion it absolutely fascinated me. I think I found my new passion in my field.

[@matthewwhite658]

Keep it going! What school @thewindsofwonder ? I started automotive school in high school because I loved cars and I realized electric cars were going to be the future. I switched to Electrical Engineering and I graduate in spring 2018 from UCF. I will be at CES in a few weeks. I hope to shake Mr. Alejandros (the creator of Formula E).

[@Francisco-j1e]

What are you doing now?

[@user-in2en5pv2u]

honest question, if formula e is to help advance EV tech, then why are we regulating the teams to all use the same battery and limit energy?

[@SoulFlavor18]

Racing still needa a control. Like 5.9L in Nascar. I do agree that batteries should be their own manufacturers but then fires could be a liability. I'm more upset that the world could've had this technology all along in consumer cars if formula E and tesla can make sport cars right away.

[@johnd5805]

because it's european bs. no one is going to save the planet. they can't even save themselves

[@johnd5805]

Go away. Shouldn't you be saving Europe.

[@teilzeitteemo6190]

the United States literally don't care about pollution and you're the perfect example.

[@badstep495]

It is simply to reduce the cost of the cars, by opening up more of the regulations the investments needed to be competitive will grow as well. Now everybody has practically the same car, with minor differences.

[@mishabm316]

Very raw explanation to be honest. Just general and basic information. I would like to know the actual voltages and currents of the inverter, details about the motor and transmission, the actual capacity of those batteries and other properties. But that's probably reserved information to be given, so I'm thankful for at least this schematic

[@yggdrasil9039]

Brilliant idea to limit power and so force the teams to compete on design. Genius!

[@turboboy1983]

FIA doing what they do best- making things boring. It's a new sport, it should be all out, run what you brung racing. No limit on output or capacity. If one team makes a massive leap then the other teams either have to copy and improve that idea or come up with something better. There's major manufacturers in this, enough with the cost control regulations.

Too few restrictions in the first years of a series is potentially dangerous regarding costs. The FIA intend to progressively "liberate" development over the years. First year, no development. Second year, drivetrain. Third year, drivetrain and suspension. Etc...

[@PyroChimp75]

I've never been into motor sport till the electric revolution picked up speed (pun intended) I'm really loving what both Tesla and Formula E are going for the future of cars! I'm going to follow Formula E a lot more now!

[@sjmzeldaavgnfan]

I´m studying Electro Mobilitly at a university later this year, I can´t wait!

[@JohnnyFPriv]

+sjmzeldaavgnfan Which University? Just wondering :)

[@sjmzeldaavgnfan]

Johnny Rubin Technical University in Ingolstadt Germany.

[@JohnnyFPriv]

Thanks, looks awesome! I wish you the best of luck!

[@sjmzeldaavgnfan]

Johnny Rubin Thank you!

[@andrellaren]

have you graduated?

[@Francisco-j1e]

The motor is so small yet so powerfull!!

[@Zitho]

It really gave me an idea of how to make electric cars move

[@raiderfandew]

I expected to learn something about E-race cars yet all I got was a lecture on HOW an electric motor works!

[@jerrynovotnik]

Yeah so the technology that actually needs improving - battery and charging - is same for all teams. And the technology that we are already good at - power invertors, electric motors and transmissions are left for experimentation. LOL

[@daryanguy]

Next season they are planning to change that

[@hyusama7469]

What!! You mean these are fully electric!! If so then that's freakin awesome!!

[@nicolasrey8791]

Yes, they are fully electric!

[@PleasestopcallingmeDoctorImath]

!!!

[@Gearz-365]

I never heard of electric cars with a transmission 🤔. The things you learn!

[@a.banana]

Porsche Taycan, 2 speed gearbox. It's a production car

[@Gearz-365]

@@a.banana Interesting. I like when cars have gears (mostly because I love mechanical things). Electric cars that actually have gears I'll accept. If not, then not thank you lol.

[@omarothman3804]

Imagine bringing portable powerbank during race

[@raphaeldias9017]

i am starting my career on the electric field . i really want know this answer , why is so important use induction motor and inverter instead of others kind of system ?

[@JohnnyFPriv]

+raphael dias Because Induction Motors produce no friction between Rotor and Stator, unlike DC Motors which need brushes to maintain constant contact with the rotor in order to have a switching magnetic field. Besides friction, it is very inconvenient to use DC Motors for cars because the brushes wear out and there would be a need to replace them constantly. On the other hand, the Inverter is necessary to convert the direct current produced by the battery into alternating current which is the type of current Induction Motors use. The inverter module most certainly also contains a variable frequency drive (or VFD for shorts) to control the motor speed and torque.

[@thetrainshop]

+Johnny Rubin besides that, you'd need switching gear on DC motors to change the motors from series to parallel field shunting to get the best power at low speed and best power at high RPM.

[@DC9848]

Great video

[@ubacow7109]

Can we have an updated formula E video on the current design and spec?

[@hugolafhugolaf]

Yeah : it sucked then and it sucks now. No one cares about glorified golf carts.

[@flessuh]

now the next step of solar powered racing cars. We do that with boats and due to innovation speed does increase each year. Plus, formula E should come to the Netherlands

[@Hidd3nsenses28]

great video

[@podracer1552]

I wish I could drive Formula E around the circuit.

[@bilal00276]

I kind of like the sound

[@Michelle_Schu-blacka]

Seems a shame that Fe hinders itself by limiting the innovation. The technology won't transfer to the road for longer than is necessary.

[@isaacchua0405]

i always thought whether or not it was possible tk use magnetism in cars

[@teilzeitteemo6190]

I would love to see how fast these light things would go when they're powered by the new Tesla P100D engine.

[@akzebraminer]

Alexander Lemcke engine?

[@generalgabrielsatori]

Formula e battery is equivalent with 4000 phones... ok now I understand why this thing is expensive.

[@supernuggetfy]

So I guess the inverter is like the ESC in a hobby grade rc car?

[@cbr7170]

You got it. You can really learn a alot about formula e when you're in the rc hobby :)

[@supernuggetfy]

Nice, the future for electric cars is bright. Assuming future electric cars are like rc cars, components such as the "esc" and motor are modular and can be easily swapped between cars lol. Imagine swapping a high performace powerful system from a sports car into an econo-hatch back lol, much easier than doing an Chevy V8 swap into say a 240sx lol.

[@SANDSHOE]

Did i read qualcom out there on the car.

[@berendh.1952]

It would be an interesting experiment to let a Tesla model S participate in a race. To top of the range model has a similar power to weigth ratio compared to these. It won't have much downforce, but it does have 4wd. I think it would be very close... But the battery still won't be big enough to last the entire race :(

[@JuzzlinOSS]

+Berend H. It wouldn't be even close. That would be like Bugatti Veyron vs F1. F1 would be leaps and bounds faster around a race track despite the fact that Veyron is "faster" and has more power. Formula E would be much faster than Model S. I still do hope that they'll arrange a Model S vs Formula E event some day :)

[@HadrixSan]

Maybe in a GT-e Championship

[@r.bennington2473]

TAMIYA in the real life 😊

[@vivekmech1]

Great technology!!! Can somebody tell me which software is used to create this video....i have been trying to find it for a very long time

[@StevDoesBigJumps]

Interesting that they don't go for an engine on each wheel like so many other electric cars use.

[@frankeinfish]

Weight is king in these cars..

[@StevDoesBigJumps]

Frankzy Well, an awd system would be worth it in my mind.

[@VitalMusic217]

yes, having a 900 kg weight, you could definetely say weight is king

[@StevDoesBigJumps]

王嘉程 Exactly what I guessed,

[@superdau]

Almost no electric car uses hub motors. There's several disadvantages to them that aren't really outweighed by the advantages.

[@dieseldragon6756]

So assuming that I understood this correctly (I'm completely new to FE) everybody has to use a specific model/spec of battery but they're free to do whatever they want with the inverter/switchgear, motor(s) and transmission (Where used)? 😇 * Sound of parts being respectfully "liberated" from a life-expired TGV and being crammed into an F1 profile... 😆*

[@justyoutubeshorts196]

Please reply me how to take the NVH consideration for the e-car???? your reply will make my great help.... thnku

[@Fetablue]

That stuff is pretty obvious. What isn't is the making behind the shape of the car. They didn't even talk about the tires.

[@darkmarksman5401]

Awsome!

[@woozhi9218]

so is the motor ac or induction

[@Tazmo99]

What is the top speed for these cars?

[@schweddyballs1163]

about 225 km per hour

[@Tazmo99]

+schweddy balls daz pretty neat!

[@kishlayverma6622]

is the electric motor induction motor

[@Quadski1]

[@clintonhalunajan467]

2:05 Permanent magnet motor I guess?

[@m22404]

why is there air intake beside the car?

[@isaacchua0405]

is it possible to recover energy(as in humanly possible)

[@Formula_Chase]

Yes, many electric and hybrid cars have regenerative braking systems.

[@isaacchua0405]

+Venomous no i mean using a Formula E car,you can right?

[@Formula_Chase]

Ginger Boy Yes you can, as most of the Formula E cars use regenerative braking.

[@gunnar6674]

In fact some petrol racing cars now use energy recovery systems (KERS), if they are allowed in the class - such as Formula 1.

[@Spido68_the_spectator]

For those who are comming here now, this video is outdated as new cars came last season.

[@YourGenericBrownGuy]

uh i kinda wanted to see how the aerodynamics worked

[@kutayarcan911]

Wait, so they use brushed motors?

[@crimsonjan89]

why dont they use graphene batterys ?

[@Hirotoro4692]

+crimsonjan89 because they're not ready.

[@Pertamax7-HD]

super batt

[@KOl-xj4jt]

self charging track think

[@Hirotoro4692]

28 kWh battery per car? So basically 1 Tesla or Chevy Bolt could last the entire race :O

[@lukechalloner]

Not necessarily - depends on how much more energy a Tesla would require to perform the same rapid accelerations and braking that the formula e cars do. The formula e cars weigh around 890Kg, whilst the Tesla Model S weighs 2100Kg. The Tesla will use much more energy during acceleration due to it's larger mass. It would be interesting to see how well it would cope however :P

[@NightmirrorXx]

Luke Challoner Kg? Isn't that kind of heavy in weight?

[@lukechalloner]

NightmirrorXx Yes the Tesla is quite heavy at 2100Kg about 4600lbs, however fortunately a lot of that weight is low down in the battery pack that sits in the under body of the car. This gives the Tesla a low center of gravity which actually allows it to handle quite well. Combine this with the instant acceleration from the motors and thats why many people say the car doesn't feel like it weighs as much as it does :)

[@yoanndouared1900]

On paper the tesla models s have better spec than renault e.dams formula e. The Reanault Z.E. 16 can go from 0 to 100km/h (0 to 60) in 4 seconds while the model S can do it in 2.7 sec. the tesla also got a better top speed.

[@gisalima28]

They talk a lot about replacing cars with fossil fuels with electric ones, but what do you do with so much lithium battery? where will they be discarded? because lithium is also a danger as well as oil.

[@monstercolorfunco4391]

That video didn't provide intriguing, tantalizing, curious facts and theories from the world of formula E. It made it sound a bit boring to me as an electrician. i.e. what's the range therefore, what's the 200kw equivalent to? what torque? what 0-60 and quarter mile, how it compares to other cars? loooads of cool comparisons and facts were omitted.

[@Vivifafaicha]

Welcome to jakarta

[@12th.jahlil]

Why cant we invest into superchargers that can fully charge the cars in 15 seconds

[@Norn13b]

The main reason is that battery technology is not quite that good. Also if you charge lithium ion batteries too quickly they will explode. This puts a limit on how quickly you can charge them.

[@12th.jahlil]

i know, why dont they use lipo batteries, and we have enough tech to focus on making it so the batteries could be supercharged Frankencycle Productions

[@Norn13b]

+eXozGaming they can make charging become much faster than it currently is, but charging a battery means that you have to run the chemical reaction backwards, which creates large amounts of heat. There are designs that reduce this heat, but if Li-ion or Li-po batteries get too hot they malfunction, so there are plenty of improvements that can be made as far as charging speed goes, but those improvements are still years out.

[@12th.jahlil]

Damn, i really want to see an endurance race with these, or atleast see these run on race tracks+Frankencycle Productions

[@chunkemonke398]

sorry if this is a late reply, but I heard they are turning the tracks into chargers. allowing you to drive while charging.

[@G33RTJEH]

The only thing that doesn't make sense in FE is "Fanboost" What a warped idea is that?

[@joselaloz]

G33RTJEH In which minute of the video they mention the fanboost?? please I watched this several times...

[@G33RTJEH]

I didn't mention Fanboost as something in this video, but as some part of Formula electric.

[@CardboardOdyssey]

It's their idea to get younger generations excited for it, not that I agree with it. Having the technology to be able to do something like that is pretty cool in itself, though.

[@greenmanpubg8728]

I making this car with self drive

[@klam77]

170kW power limit means, for a 24Volt battery, 7000 (thousand) amps limit. Seriously? do you think these motors can even TOUCH 7 KILO AMPS for even a MICRO SECOND?!!?! FRY EVERYTHING! The power limit is clearly not a limit at all.

They can, this year the power limit will be 250Kw.

[@truth-12345.]

Why can't they just follow Tesla's framework and battery engineering?

[@cheavichit9997]

I've just skipped math class and then KZbin recommendation bring me here. Right now is time to skip the Earth

[@rj_ay8172]

Why do formula e cars have gears but road evs don't?

[@carlosandleon]

Zadok the Priest cause gears don't really make any sense in an e car. you have maximum torque from the start

[@rj_ay8172]

Carlos Leon I presume the torque starts to drop off after some time, yes?

[@badstep495]

This depends on the requirements, an electric motor has a wide RPM band (sometimes up to 20.000 RPM, compared to a combustion of roughly 1000 - 6000) and a pretty consistent torque output (limited by the power, rpm * torque). If you have sufficient torque throughout the entire speed range on the circuit (Formula E also has low grip tyres), then you don't really benefit from extra gears. Some teams probably believe they need the extra gears to have some extra top speed or torque at low speed, while others decide to go with direct drive and save weight.

[@klam77]

it's a long "chain of throught": in theory the gears allow the motor to operate at peak efficiency torques/rpms, operating the motor at peak efficiency means you get more out of the battery.

[@klam77]

They are charging $85 to see the race. Too expensive!

[@T1Oracle]

28kW? Tesla has 90 in a family car.

[@killy1]

+T1Oracle The tesla is far heavier and has a number of motors to compensate for this hence the greater total kW. This race series is in its infancy and is created to promote who can design/implement the best equipment rather than afford/squeeze in the most powerful parts available already.

[@T1Oracle]

killy321123 A RWD Model S has 1 motor just like these cars. These things only have 250hp and 28kW. That's just lame giving the power and battery capacity of a Model S. I hope next year they bring those up to a level more suitable to racing.

[@spiritusinfinitus]

+T1Oracle It is probably wiser to start smaller and develop the technology methodically and build up the series gradually in baby-steps rather than risk complete failure from season one with a series of monster F1 killers from the get-go. Less resistance on this path (if you pardon the pun).

[@T1Oracle]

***** No. Not really. That's why Tesla sells more EV's than Nissan right now. Starting small isn't the answer. If you start as big as you reliably can, then you generate more interest and things can take off. If you start too small then people don't see the value and lose interest. Having a strong head start in popularity is invaluable.

[@spiritusinfinitus]

+T1Oracle Well, I guess the investors and sponsors involved the FE series probably disagree with you, judging by how things actually are. ;)

[@randy109]

Since these are just GIANT Slot Cars anyway, why not run the power through the track or through a giant metal screen 8 feet above the track (like the "bumper cars" at the Boardwalk)?? I love to see anything race so this has a chance, but I put away my Slot Cars 45 years ago to build Real Cars. Whether watching Formula E is going to make it profitably really depends on a LOT of NASCAR and Formula 1 fans switching back to their childhood to watch GIANT Slot Cars on a Sunday afternoon...
