You forgot to talk about one of the main reason why the batteries are round. They use a cooling system for the battery cells that goes around the cylinder batteries. One of the main reasons for the battery efficiency of tesla car batteries is that they can easily keep the cool.

My new house will have a *Tesla SolarRoof* and a pair of *PowerWalls* (among other whizbang renewable tech)... 11 days without power in the _sweltering_ SW Florida summer after *Hurricane Irma* is not something I ever want to repeat !! I’m stupidly excited and really happy the *SolarRoof* became available... I live in a _“historic”_ neighborhood so now I get a solar PV system without the headache of the local hoop approval !!

Please make video on electric vehicle calculations such as range at top speed , range at given speed , coefficient of drag , rolling resistance , initial power and torque needed to start the electric vehicle , how much energy needed for a specific range , how much energy needed for a specific speed ...

can you make a video specifically about battery recycling? what is the current technology for that and how spread is it in the world? the newest critique for lithium-ion batteries is that it pollutes the source place where most likely poor people live.

Hi Curious. I love your videos - they give a great overview of some very interesting topics, with just enough dept to learn something new every time :) I was wondering about one thing you said in this video though. At 5:05, just after talking about battery cells, you say: "The core technology of Tesla, however, cannot be easily copied by other manufacturers". Would you please elaborate on this? Specifically: Which technological advantages do Tesla posses on a cell level, and why can they not be easily copied? Thanks in advance :) -Peter

Love you your videos

Original technology was from the battery called eneloop. Bought by panasonic from the soft energy division of Sanyo Electric which developed the technology that until now has not been surpassed by any commercially produced cells

When you say it could be driven with one pedal I got a bit confused. I was under the impression that the further you depressed the brake the more the induction motor would tax the vehicles speed by spinning faster in reverse to charge the batteries more. Panic braking and the final halt to be provided by the brake pads. Is this not the case?

omg this video is so great

I think that the 2170 battery also have a different chemistry, so the 2170 IS better 1865. I remember hearing this in a quarterly investor call with Tesla.

@CuriousElephant

In the call, its said to be 20% better. the thing is, the fundamental chemistry is not different, it more about how the chemistry is arranged so that the Lithium ion can be "absorbed faster'. So as a cell, 2170 is better, for its size

Yes, it is not fundamentally different, but the energy density is 10-15% better in 2170 compared to the 1865 Elon pointed out in the call.

It would be interesting that EV have connectors that we could connect our houses, computers and all electric stuff to take advantage of all this power.

So overtime batteries are prone to wear and tear and gonna need to be replaced ?

They're did 22,300 deliveries in September 2018 of just the model 3 alone, and has ed gotten the battery prices down to $100-103 per kwhr

I like this type of car batteries because if you crash your car, those little pieces would just get scattered all over and have much more chances to remain unbroken. If you have 1 big solid housed battery, on every impact they will get broken and leak and explode or whatever. I think this type is way more safer then other types.

5:00 you said the core technology can't be copied, you mean battery technology? but isn't it the technology of the battery manufacturers like Panasonic and CATL?

Someone may have asked this already, but I thought the cathode is the negative electrode and the anode the positive? He said electrons flow from the negatively charged anode to the positively charged cathode.

How safe are these? In collision or in daily use.

You missed the biggest difference between the 18650 and the 21700, which is power density. The 21700 cell has been claimed to have 40% more active battery volume, even though it is only slightly fatter and taller.

The vape community knows more about this than most people ever will I'm glad to see someone who understands haha

i think grafeno it's another possibility. for future batteries.

Tesla needs to get its quality control up. And by a lot. It's easy to build a few luxury cars. Making affordable quality cars in large numbers is something that Tesla still needs to learn.

I'm a bit confused about what you said. You said that if someone tells you the 21700 batteries are better than they are dead wrong, and directly after saying that you said the 21700 batteries are better due to a higher storage compasety. Or did you mean if someone said it's better just because it's a higher number. Either way I did like the video, but clarification would be appreciated.

correct me if I'm wrong but you say that one battery is not better than the other, then in the next sentence you say the form factor is better in the 21700. Making the energy density ratio better, wouldn't that mean it's a better battery?

According to Doug DeMuro and Chevrolet official site www.chevrolet.com/bolt-ev-electric-vehicle it is Bolt. This doesn't mean i not appreciate the info, very nice done thanks. Just car enthusiasts and people should be able to get it right :)

I think until and unless we get a major battery breakthrough, like the development of solid state batteries, electric cars will continue to be a niche market. It is possible, however, that for urbanites like myself we will move toward occasional renting of electric vehicles rather than owning gasoline vehicles.

My take in the Musk / Tesla strategy, 1) Keep a close eye on new developments & what is coming, don't lock yourself too firmly to one exact technology. 2) But don't sit and wait for hell to freeze over! Get started with manufacture and use right now, on a scale that can create economies of scale, and be ready to drop one technology and pick another as soon as it comes online. Change and adapt and move forward, but do that while you make cars! If you wait for the picture to stabilise, then you'll still be waiting in 100 years... 3) This is not going to be easy. Well, landing rockets on a barge, after they've launched a couple tons of orbital cargo, that's not easy either...

Problem is: Ramp up energy density means having progressively more instability and risk. A current battery is considered quite at the verge of being too dangerous already... I guess, charging and recharging capabilities will be more in focus, than really trying to squeeze in 10 times or so energy. What I always wanted to know and I will look it up.....what capacity and c-ratings do their batteries have. If you are into model flying, you exactly know about every single problem of longevity, puffing, etc. -> All those people know one fact: Those batteries are divas. This whole supercharging stuff still is in question for me. The best you can do and that is, what most of us luckily do anyways (so it is great): Come home and charge on reasonable speeds over night. This will be good and naturally achieved by most of us during normal use. I just find it funny, that so many people talk about supercharging and all that stuff. Increase the range just a bit more reliably and you cater most of us already.....no need to talk about recharge times for 80% of us, as we do not drive more than 400 km a day! :) All nonsense to even talk about it, as hybrids or even other new technologies can easily serve better for longrange driving.....or such travels will be handled completely different than we expect (long range traffic systems, other kinds of long range travelling, etc.). Future is not about just going all in of what s considered most advanced or something. It is about seeing, what different tech can do best. You will not suddenly build batteries with 60 times the energy density, that comes close to chemical fuels....the nature of a device having to charge and recharge cannot simply compete with a energy packed chemical substance, that disappears essentially after using its energy. It is a one way ticket vs a reusable device...nature did that stuff for a reason (fat, sugar, etc.). So for me, it is thinking about most suitable and at the same time effective solutions. And those are not EV only or such things. It will be a mix, because completely going EV as fast as possible wont work with our currently fast world and its needs. If we would all sacrifice stuff signifiicantly, we can perhaps reach such state of society. But as long as we are all some sort of relentless consuming beasts on our planet, you cannot simply go green in a blink of an eye. Every reasonable thinking individual knows that and yes: The other companies will be more reasonable about it. You will have standards and can choose between all cars and you will always find suitable charging stations, etc.....something that a tesla (though part of the consortium) isnt currently going for. They just are all in to grow their tech achievements to the fullest...sacrificing a lot of its sustainability. Why? Because they must have a good headstart or they will be crushed in a matter of months. It is an all in situation.

li-air is years, maybe decades away - yes progress has been good but its not nearly where it needs to be - necessary progress will enable loads of next-gen li-ion batteries in its wake such as li-metal electrodes and inflammable electrolytes
