The Truth About Tesla Model 3 Batteries: Part 1

Today we are going to talk about “The Truth about Tesla’s Batteries.” If you’re thinking about a Tesla, you’ve undoubtedly heard about how cheap they are to fill up, how little maintenance they require, and with recent Model 3 Production ramp ups, we’re on the verge of absolute Tesla ubiquity. But one of the questions that we believe keep potential buyers up at night, surrounds their battery packs. So we’ve compiled a list of all the questions we’ve received, and we’re going to break it down, step by step in this two part video series.
*NOTE* We incorrectly converted lbs to kgs in the costs. So Please go by the price per pound! Lithium = $7.50/lb, Nickel = $4.05 /lb, Manganese = $0.93 /lb, Cobalt = $36.50 / lb

[@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.

[@vinceandtheresa1243]

[@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!

[@poneill65]

On the question of why thousands of cells rather than fewer, larger packs, I believe there are several factors you didn't mention. 1) spreading the charge/discharge current over more cells allows Tesla to charge and discharge faster without overheating. 2) it is harder to cool larger cells than small ones (the internal heat source is further from the external cooling system) 3) degraded/dead cells represent much more of a range loss with fewer, larger cells Also, I don't believe panasonic would agree that the relationship is symbiotic or beneficial. they're apparently pretty pissed at how little they make out of the deal

[@mikedufour]

Tesla batteries represent the HEART AND SOUL of their business, which is why the class action lawsuit addressing the software update earlier this year that fraudulently cut Tesla owners battery capacity by 11% is so concerning. They lied stating that it was done to protect battery health and overall longevity, but it was really pure COA in order to both protect their own interests as well as prevent more fires. Their choice to deal so underhandedly with their own battery issues should cause most people to have legitimate trust issues in regard to doing business with them as, again, batteries represent the very core upon which their business is built.

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

[@X_platform]

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.

[@vinylmodsmanitoba]

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...

[@vinylmodsmanitoba]

@@MmeHyraelle They dont use 18650 anymore, not since they started production on the Tesla Model 3. Now they use their own modified version of the 18650, its taller and wider but double capacity to a max of 6000mAh and uses more reliable materials.

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.

[@listerdave1240]

@10:00 regarding round vs flat/prismatic. AFAIK there is a much more important reason - the lifetime of the battery. With a cylindrical cell it is easy to maintain pressure on the layers in the battery to keep them from coming apart as only tension in the circumference is needed. With flat/rectangular cells this is much more difficult and would need an extremely heavy metal case to provide the same pressure against delamination. We've all seen smartphones with a bulging back, or even a broken screen due to the battery expanding. Now while the exp[ansion is itself a product of battery deterioration once the layers loose contact the process accelerates and the battery deteriorates even more quickly. On the other hand a cylindrical case will maintain its dimension regardless and keep the layers in contact, any pressure in excess of what the cylinder can take being released at the ends.

Reading all these comments, I'm not even going to watch the video. Y'all should just redo it with the correct math and reupload.

[@kuhrd]

The small cell idea is a good one in the beginning when they have to deal with outsourcing battery production, but in the long run, they will be far better off to use larger prismatic cells instead since it really doesn't cost that much to produce the cells in any shape you want and with larger prismatic pouches you gain better thermal stability and easier cooling along with better safety since prismatic cells will expand during a fault condition which tends to break the connection rather than starting a fire. Even if a nail or screw were to puncture the pack.

[@TwoBitDaVinci]

How is cooling easier?

[@kuhrd]

Tesla had to create special bent cooling tube plates to fit in between the cells so that each cell could be individually cooled and this makes the pack construction more of a pain even with advances in production. It also leaves the possibility that some cells will not have good contact which may affect the longevity of some cells over time. With prismatic cells, you can use flat conduction plates that are easily stackable and make contact with one large cooling plate that can cool the entire pack and maintain the same temp across the whole battery compartment. With larger prismatic cells you also have far fewer points of failure.

[@TwoBitDaVinci]

[Ricky] How often is coolant run in a prismatic cell? Between each layer? Of course not, I'm not sure exactly which care you're referring to, but Tesla has a patented wavy coolant manifold that touches each and every battery in their packs. This surface area, to volume, gives them exceptionally good cooling, and I've yet to hear of any prismatic battery that comes close. Please send us any links with specifics, and we can always do future videos!

[@kuhrd]

It really depends on the manufacturer. Most use a thermally conductive plate between cells that also provides added rigidity and support. They can then cool one or both sides of the modules. Some manufacturers do have manifold plates between every other cell but this is not really necessary since the larger prismatic cells tend to dissipate heat fairly well. Tesla's bent tube manifold design does not guarantee thermal contact for every cell, especially when they go through a few thermal cycles. That is part of the reason why they had to use thermally conductive glue for the model 3 pack assembly to attach each cell to the bent tube manifold they have snaking through the pack. With the model S packs it was very possible to get hotspots. The prismatic cell design allows for a much larger cell package with as much cooling as needed in just about any configuration with fewer parts to minimize construction time and simplify control.

[@nordic5490]

kuhrd, 2 words, coolant circulation.

[@edsalinas9996]

In part two, I hope you talk about the Lithium batteries catching fire. Tesla needs to control that problem a lot better.

[@TwoBitDaVinci]

The studies are out, your gas tank is more likely to catch fire than their batteries. Look it up

[@stevennerheim3739]

[@TwoBitDaVinci]

[Ricky] All kg prices are wrong we divided instead of multiply, we made a note in the video description! Thank you!

[@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. :-( .

Did you miss the part about batteries?

[@TwoBitDaVinci]

Possibly a future video!

[@antizakkonic7789]

I hear ya.

[@mexicanracer03]

Great work. Keep the good coming and all these people being negative shows they don't have the capability to make an informed video like this.

[@Rambleon444]

At 3:40 In the video he explains silicone anodes expand 300% -400% compared to the older batteries with graphite expansion 7%-10% and "this can be a big problem". Seems to me this can be a HUGE problem. The oldest EV with the silicone mix is less than 2 years old. It will be interesting to see how the new batteries hold up especially if the owner does big drains and fast full charges causing massive expansion and detraction of the anode.

[@TwoBitDaVinci]

old cars use graphite, silicon is a future technology that has challenges that need to be solved.

[@Rambleon444]

Need to be solved? Yet they are using the silicone mix since 2016. And as you said in your video in the 2018 Tesla's they are probably using even a higher amount of silicone than the 2016 models. They either solved the expansion problem or there is going to be a lot of pissed off dead battery Tesla owners.

[@TwoBitDaVinci]

its a very small percent, sorry I thought that was clear in the video. The idea would be to increase that percent more and more.

[@lylestavast7652]

good job explaining the cells strategy. Interesting times - with Tesla model 3 ramping, we'll see it all prove out well or flop on it's own weight... I'm wishing them well !

[@TwoBitDaVinci]

[Ricky] Thanks, yeah its the most critical period in their history and its great knowing they've put so much thought into everything.

[@kurtjensen7264]

Lyle Stavast well you you just got your wish Tesla has even out sold some of the more popular gasoline cars in the Tesla three and they haven’t even caught up to all the customers who are buying them now imagine when they catch up to the people who want them and that day is closing fast.

[@lylestavast7652]

Ummm... not sure why it was really all that critical to specifically state it - isn't it generally understood that that is why it's called what it is ?

[@lylestavast7652]

October and November numbers are really critical, as are the 3Q18 financial results due out maybe the 1st week of November. You can see all the plugin player vehicles (pure EV and plug-in hybrids) in the space at this site - which shows Tesla just completely dominating the space now... insideevs.com/monthly-plug-in-sales-scorecard/

[@lylestavast7652]

actually they are going to announce 3Q financials on Wed, 24 October... that was announced on Monday night 2 days before... bode well, or ill ?

[@lbmitchell1777]

The day will come when Tesla makes a battery that will last 1,000 miles/charge. That's what I'm waiting for to buy one.

[@firmman4505]

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?

[Ricky] Dodge Chrysler Jeep is one of the most unreliable and poorly made cars out there... I'd rather Have Tesla... but Comparing Tesla to the likes of Honda or Toyota... yeah It'll be a while for them to catch up

[@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!

[@lanedexter6303]

Backward figures in there, higher dollar price per lb. than per kg (which is 2.2 lbs.).

[@IvanBaas]

he thinks kg is less then lb I guess ahhaha

[@mschorer]

Great research and presented with a nicely paced voice! Thank you very much!!

[@charlestondarwin]

great video. One small correction: 1kg = 2.2lbs so the price of lithium looks inverted (the video says $7.5/lb or $3.41/kg)

[@TwoBitDaVinci]

Yeah noted that in the description

[@mv80401]

The advantage of small cylindrical cells over prismatic cells is superior heat dissipation.

[@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.

In my view and having been around very creative individuals all my life, which consisted of all facets of engineering and entrepreneurship, my opinion of Elon Musk, is he nothing short of genius. If one studies what he does totally, he has a complete unending goal which is all connected. I’ve become obsessed with this mans genius and convictions. For the sake of many, I pray he continues. He is one to watch and emulate.

So, the batteries are getting more explosive. Stage four: lets use potassium batteries. Lithium doesn't have enough explosive power. Anyway, the prices rising are good news. It is a motivation to look for safer chemistries.

[@imakevideos5377]

nope they are not getting more explosive, not a single tesla has ever exploded in the same way as a petrol car can
