[@GregPeden]

Another very important reason for using several large cylindrical cells is cooling performance. The cooling loop is wound through the batteries and the cell size is optimized for an ideal surface area-to-volume as determined by the necessary worst-case cooling performance. It also reduces the risk of a cascading fire since the energy in each cell is smaller, and it increases the system-level tolerance for cell failure since a failed cell will either fail to conduct or short and cause the fuse to open, and in either case this will have next-to-no noticeable effect on the battery overall since each battery pack features several thousand cells.

[@TwoBitDaVinci]

[Ricky] Greg you're getting into part 2, yes we will cover that extensively just you wait ;)

[@rogerstarkey5390]

Greg Peden Good point regarding the surface contact area of a cylinder!

[@GregPeden]

Sounds good, this is the design aspect that Nissan keeps absolutely flubbing over and over again, to me their ignorance of the importance cooling performance is astounding, doubly so since they also owned their own battery production until very recently, and ALL of the automotive companies have way more experience with liquid cooling systems than Tesla does.

Kg-pound conversion is bad. 1 kg = 2.2 pounds, so cobalt is about 90$/kg, nickel is about 10$/kg and so. As a kg is bigger than a pound, 1 kg of something cost more than 1 pound of that. Put correct quickly

[@smwcom]

[@stevebothe1416]

A couple of things I noticed that you missed. Whilst Panasonic own and operate the cell manufacturing side at Giga Factory 1, Tesla have been instrumental in developing the various cell chemistry's and form factor. Also, the latest info from the last share holders meeting, it was mentioned that the next generation cell would be cobalt free.

[@justsomeaussie]

Steve Gigafactory is Tesla own and run (it’s Tesla’s name on the side). It’s that Panasonic has significant invented in it and provided the manufacture expertise and machines. They are the cook to Tesla’s recipe

[@stevebothe1416]

Exactly what I was trying to say...

[@TwoBitDaVinci]

[Ricky] so manufacturing process, optimizations in size per density and price, are where Tesla shines. But in terms of Battery chemistry, Panasonic is king. Great comments, we are so blessed to have such an amazing community of people like you with such good insight. I'll look into the next generation of batteries ,and if they are indeed Cobalt free. thanks again, we hope you'll subscribe, you the kind of person we need in our journey.

[@TwoBitDaVinci]

[Ricky] Yes absolutely great comment

[@ABaumstumpf]

"Tesla have been instrumental in developing the various cell chemistry's and form factor." They use a standard form factor.......... and the chemistry too isn't all that special. Other manufacturers just have oped for cheaper alternatives with slightly worse performance characteristics but also a lower environmental impact and with a reduction in the reliance on controversial materials. And Cobalt is instrumental in the lifetime characteristics of LiIon batteries. Change that and you are back to bog standard 18650.

[@davidkreimer8800]

Another big plus for small cells in Tesla is that each small cell can be quickly cooled of or warmed up, quickly, if necessary. Lithium batteries hate being too cold or too hot. In the Tesla packs, each small cell is partially wrapped by a liquid cooling 'blanket' that can provide cooling , in the fast charging mode, or heating, in the artic like conditions. The cabin A/C provides colding. For hoting, all on board hoting areas are used(ie...computing heat and whatever other heat sources can scrounged up) . If that isn't enough, resistance heaters are used from the battery, and this is a significant battery drain which leads to big losses in m.p.g. The colding losses are smaller.

[@TwoBitDaVinci]

You’re talking part 2 ;) yes great points!

Great video, sub’d for sure. One important thing you didn’t mention about Tesla’s small cylindrical cells vs the larger flat cells used at the competitors, is that the cylindrical cells have a much greater lifespan due to it’s physical shape, it simply can’t expand and contract as much as a flat cell.

[@TwoBitDaVinci]

Yes, especially in the Model 3 where they have aluminum cooling radiators that surround each individual cell, this is why it doesn't overheat like other EV''s and can be tracked: markets.businessinsider.com/news/stocks/tesla-stock-price-has-remarkable-battery-tech-that-has-been-largely-overlooked-2018-6-1027327792

You forgot one very important part of why tesla uses small cells instead of bigger cells. This is because of reparability and refurbishing. In large batteries that are solely produce to fit a specific design, the interior design of the battery makes it hard to isolate problematic portions of the cell. But with smaller cells like what Tesla uses, its much easier to find the problematic cells, remove them from the battery pack and have them recycled. This leads to a much smaller percentage of the battery pack needing to be replaced upon imminent failure.

[@TwoBitDaVinci]

[Ricky] Didn't forget, that's in Part 2, where we talk about the battery pack!

[@WheatleyOS]

also thermal control is much simpler and safer, that was also one of the major reasons behind going for small batteries

[@frien_d]

Reparability = bullshit. It's just a design they embraced from day 1 because they had to use off-the-shelf computer parts to fill their Lotus Elise. Now they're optimizing, but, still, there's need to cut costs, so they will keep almost the same kind of harnesses and just make their custom cells, cells that they probably custom-ordered from a laptop parts maker in china.

[@MmeHyraelle]

Also, the cell used are already common format, the 18650 format is the most prevalent one in vaping devices as it can deliver a lot of power in a burst fashion. ( my lg hg2 are rated 20A continuous and 35A burst discharge rates ). But only 3A/h of capacity...

To my understanding the configuration of cylindrical shape of battery is safer as well. Each sheets of metals are rolled up together to form the cylinder. During rough drive the vibration force exerted on each sheet is tangent to the cylinder. For comparison, non-cylindrical battery, during vibration the force is perpendicular to each layer.

Thanks, in the early 70's I worked driving a propane poll hyster, hauling rolls of carpet. The company had a new ideal of doing things. They brought in this much smaller, total electric poll hyster. All of hyster drivers thought, "no way, this little thing can handle the work load, can't possible do the job". Well needless to say, after a week or so of using this smaller total electric hyster, well all fell in love with it. Much fast and, no fumes,, and could pick up more rolls because it was smaller. Faster on everything and only once a day did we have to change out this huge battery. A batter about the size of 4'x4' huge battery. Done with a crane at a place where it was done quickly 15 minutes tops. The whole plant eventually changed to "all electric". The little things were so fast we had to have a class on how to drive them slower and safer. Carrying possibly 3 to 4 tons of carpet can be dangerous. So electric is where the country needs to be. I'm guessing I will love Tesla but they are pricey. I'm not sure which one to buy. 310 mile range on the newer S models or a P 90 much faster but older one. I found one for 62 thousand a used one but a new Model S is about the same. So new or old? I truly don't know. Thanks for your video.

[@TwoBitDaVinci]

Indeed

[@izoyt]

it's waste of materials, time and energy, if you can make battery 3 times faster and cheaper with regular manufacturing. 1852 (or this new on, slightly bigger) format was not invented for use like this. and this is place where tesla fails, it is just too expensive, and without some heavy sponsorship from state etc, musk would be just another business man, talking about science.. and talking buisness: better not to talk about it, when comes to tesla inc., their loss jusr keep growing year by year.

Would just like to complement you on this production. Very well laid out and delivered. Top notch. I found it very informative and even let the adds play in hopes you get paid for your efforts. It did throw me off a sec with mostly American dialect then pronouncing aluminum as a Brit😉 Subscribed👍

12:00 so you can perhaps say.. Panasonic is Tesla's mitochondria

[@101perspective]

Lol... You start the video with the question of whether making the batteries is worse for the environment or not. You spent the first 9 minutes apparently building up to an answer... then tell us you don't plan to answer that question in this particular video. Wtf?

[@electrictroy2010]

I thought I’d hear “the truth” about why Model 3 production is so slow/troubled. Instead I just got a list of battery ingredients. :-( .

Can we just be honest its in 2 parts so you get more views, and hey I don't blame you lol, great video I'm off to watch part 2

[@TwoBitDaVinci]

No it’s in 2 parts because we spent 100 hours in research, 100 hours of 3D modeling and rendering, and 30 hours video editing. We couldn’t make it all happen in a two week window. Cheers!

How comes that 1lb of the same material is more expensive than 1kg of it since 1kg is more

[@TheSPAZZANATER]

i agree. tesla is still a new company. in less then 10 years they will be up there. the only thing right now that makes me not want to support tesla as a company is the lack of consumer available parts. they are very bad about that. i do hope that is to change in the future but i have my doubts

[@TwoBitDaVinci]

very good point, I think this is a topic many have raised as a concern, and we'll try to do a future video on it soon!

[@magy357]

Hi. Great video, but I do not understand your math in 5:25 time. If Lithium price is around $7.50/lb, how can be $3.41/kg? As far as I know, pound (lb) is 0.45kg, which mean, the price for kg should be a bit more than double of price per pound. Not vice versa. (Same with Nickel, Cobalt, Manganese, Aluminium... ) Isn't? Update: Sorry, I did not seen your note under video about this at first moment. OK. Fair enough.

[@TwoBitDaVinci]

[Ricky] Yes our apologies, we'll sort it out in our part 2, and we'll do better going forward!

[@VikingRul3s]

Exactly my thoughts. Well i was thinking "DAMN gonna buy in kg and resell as lbs" xD

[@Zootalaws]

$4/lb = $1.82/kg? $40/lb = $18.20/kg? Math doesn’t work.

[@americanlivesmatter-BmanWild]

$4/lb = $1.82/kg? $40/lbs = $18.20/10kg? This only fixes your hypothesis in equalateral havent watched the video yet or know what you are talking about thanks.

[@americanlivesmatter-BmanWild]

Also still noticing holes in price ..sounds like a punsy scam bro ..avoid it

[@Den99973]

With this subject being so technical, how do you manage not know that kg>lb . As a result, how can lb costs more than kg?

[@TwoBitDaVinci]

Read the description

[@patricialawson6749]

The electric vehicle batteries are charged in the garage at room temp (+ 20 Deg C.) How much energy is lost from the battery at minus 20 Deg. C or at lower temperatures ? Regards, Patricia,

[@paulstandaert5709]

I can't get over the fact that in all my years, it has been very uncommon to have *any* battery outlast the device that it goes into. Drills, computers, phones, emergency exit lamps, etc. Then factor in the self-discharge rate. Use it or not, the car is going to be dead in 10 years. I hope I am wrong, but just because a Panasonic 18650 cell is dumped into a car, it is supposed to last longer? Battery technology has a ways to go yet.

[@TwoBitDaVinci]

Paul I’m working on part two as we speak! Please subscribe and wait for part two on Saturday! I’d love your feedback after seeming it

[@davidatherton994]

Paul I am sorry, but to put it politely, you have literally zero idea of what you’re talking about. You simply can’t compare a drill, laptop, phone etc with a car. The battery management is like comparing cheese with chalk. I have friend in San Diego with a 2012 Tesla, still going fine, still on it’s original battery, LOTS of miles on the odometer.

[@paulstandaert5709]

We will see. Like I said, hopefully I am wrong. It would not take much to implement battery management into a laptop computer, nor a battery drill these days but nobody does that. If you go to flea markets / swap meets, they are littered with battery tools. But they almost never work. If management is the cure to the problem, I wish they would implement it. How many miles is "A LOT?" To some people, that is 70,000. I have 20 years and 248,xxx on my Jeep. It is like one of those car ads where they advertise "Low miles" or "high miles". The odometer only tells about 1/3 of the story anyway. This guy probably has his own home where he can charge the thing daily, combined with the temperate climate of San Diego. It probably lives a good life. As with any car that lives a good life, it'll be a long life. And miles miles miles. It is only 6 years old... maybe 7. Give it another 4 years, and lets see where it is at.
