Serisouly though who wouldn't support you on Patreon after enjoying such a well made content. Thank you ;)

[@TwoBitDaVinci]

Thank you so much for saying that... it really is motivating :) We have a lot of great stuff in the works!

[@eotmanoftheyear]

Two Bit da Vinci, very impressed. Thanks for the insight!

[@philiprowney]

First visit to your channel and you can't convert units, not a very good reason to follow you. Inaccuracy kills a source.

[@L3uX]

Two Bit da Vinci Pretty much spot on. But did you mention that the rear motor can be used in waste heat mode to heat up the car really well, especially start ups for the days beside software preconditioning/predictions.

[@douglasbkerr]

One tiny little quibble: You mentioned that you should cut back on the seat heaters to extend range. Using the seat heaters on an EV uses very little electricity. For that reason, it is suggested that you USE the seat heater and cut back on the cabin temperature. Seat heaters are your friend.

[@TwoBitDaVinci]

sure this is a bit subjective. The same resistive heating elements are at play in both, so based on number of passengers, and personal preference, do what works for you! I like warm air on my feet

[@douglasbkerr]

I get it. In the low range days of 75 to 85 miles, people would go to extremes in order to keep warm; blankets and boots were the norm. And thank you for all your hard work. I've owned five EVs since 2013, and around ten fossil cars. My Model 3 is by far the best car I've ever owned.

[@compu85]

The dash heater can draw thousands of watts. The seat heaters are in the low hundreds.

[@TwoBitDaVinci]

Yeah, you can set the heat to a lower setting, you should factor comfort, preference, and number of occupants. But do what makes the most sense for you, and do some experimenting! We'd love to see the data from anyone who does it!

[@CubbyTech]

Not really - most electric seat heaters use 90-120 watts of electricity. The electric-resistive heaters inside EV's range from 2500 - 6000 watts or more.

[@colddesign12]

You recommend not running seat heaters, but it's much more energy efficient to run those with reduced cabin temps since the heat is direct to your body, and not dispersed through air in the cabin.

[@TwoBitDaVinci]

Yeah that is purely up to the user. Seat heaters usually aren’t enough for me. I prefer heat on my feet. But you’re totally right the heater in the seats use less energy than the cabin heater!

[@larryspiller15]

Seat heaters are fine up to -5/-10°c but colder then that you need the air too. At least my opinion. Maybe you live in a warmer area then myself, maybe not though

[@mattlane2282]

If you spent that kinda money on a car... your gona sit in it and be cold? LOL. I'm toasty warm in my POS 80's diesel...

[@colddesign12]

@Matt Lane you might be focusing on the wrong thing here...

[@OldFormat]

Living where I do, I literally never turn on my car's heater. A/C runs for 9 months a year though.

[@PRUDENCEIAS]

This side of KZbin is called: knowledge!

[@Legominder]

7:42 Third reason: Cellphones and Laptops don't have temperature controlling keeping the battery at proper temperatures when charging etc.. All in all these information, despite a few unironed spots, are incredibly well-prepared and also well-presented. Calmly, allowing to focus, think and understand. Thank you very much for your incredible work.

[@EleanorPeterson]

Just wanted to say something about the cold weather points mentioned. I've no experience at all with EVs, but my old Nissan Micra (1 litre petrol engine) never let me down in cold weather. It was parked outside all year and started first time, every time, however bad the winter. I bought it third-hand in 1996 and ran it happily till 2012, when I suddenly became poor, sold it, and went back to riding my old bicycle instead. I'm not sure where the idea that petrol cars can't handle freezing conditions came from. Diesel fuel IS affected by very cold weather. I think most lorries and trucks with exposed diesel fuel tanks have heaters to keep the fuel flowing in below-zero conditions. Once again, though, as far as I know, they start and run without any fuss in winter.

[@byram101]

This was incredibly well done.. easy to recommend this as one of the best layman's breakdowns of this technology I have seen. Each of the 160K of us that have seen this so far.. have come away smarter from this well though-out presentation. Kudos to you for this.

[@TwoBitDaVinci]

Wow ... that's a great compliment, thank you so much!

[@jnrivers]

LEAF's use a HVAC system for heating and cooling generally. The lower trim level uses resistive heating. Also, heated seats are dramatically more efficient than heating the entire cabin.

[@irfanalam1524]

really appreciate the last mentioning of your effort in the making of this video

[@williamtakacs7466]

You tell truths that I agree with. Must caveat that by stating I've not seen the entire video and may or may not agree with some of your assertions. That aside what I have heard resonates. I was immediately on the heat problem, which you immediately explained in a clear and concise manner. Cuddos Dude! :)

[@davefoc]

What, Tesla inverters don't look like clutch plates? Who knew? Maybe you could get Tesla to change their inverters so they look like clutch plates so the image in your video would be right.

[@dizzywow]

It would be nice to see Tesla offer a manual tranny, as an option! 8)

[@nightfly4664]

I went into this video expecting to feel worse about my car, but now I feel even better about it!

[@EleTruk]

Cute that you use a clutch plate as the figure for the DC-AC Inverter (which you called AC-DC inverter, which is backwards, AC-DC is done simply with rectifiers).

[@TroyeWelch]

Ele Truk and yet there is still some nutjob insisting that Tesla is supplying him with their own graphics. lol.

[@TheIdiotPlays]

15:58 -27C here in Finland last winter. My 2004 polo, semi faulty ignition, broken lambda, broken catalytic converter, leaking exhaust system. Starts with first crank albeit sounds a bit rough. Though that thing sucks money like a leech when you fix the issues it has :P

[@Kvickification]

He meant Diesel not Petrol engines.

[@Deathwalker666666]

Even modern Diesel diesel engines does not require those gadgets. Whats great about those shots of the cars is that maker of this video does not know european car plates since those cars are from Russia where winters generally are way harsher than the -27C. And from what i see those shots the cars are from Tomsk Oblast are if you want to know thats West Syberian Plain which means in those EV probably would not even start during the winter.

[@rodrigojds]

your car battery must be brand new then!!

[@Deathwalker666666]

You know you just defeated the whole point of having EV by your sentence, because it just show how much of denial. Great idea brand new battery for every winter. The thing even if manufacturer of battery says it can work -27C you really don't want it work in those conditions(in other words do go with your EV cars anywhere with temp. lower than -22C) since it would damage the battery so much that you will need a brand new one.

[@ihavenoidea4727]

I have a car fail to start every winter in finland. And ive owned 5 brand new ones. Joka vitun talvi

[@garthwoodworth3558]

You guys are making a professional effort to provide valuable information for everyone interested in Tesla. I have had a Model S for more than 3 years, and as much as I keep up, reading almost every article and seeing a great number of videos - your information and presentation is the most accurate, dense and complete I have seen. I have a recommendation: since you appear to be on track to basically create a 'Tesla Encyclopedia', I believe you might enhance the value of your project with an indexing system. An indexing system could be as simple or as complex as you choose to design. However, I see a complexly designed indexing system as eventually generating great rewards for both you and your viewers. It would be a big undertaking. 1. Simplicity from the start would only need to categorize your videos by subject matter - a 'table of contents'. 2. More complex would be to create an interactive tree of related material organized to send researchers logically to the level their prior research indicates would be most useful them, i.e., answer their questions before they ask them. 3. Much more complex would be to access timestamps within each video so that keyword searches could provide your viewers with links to related snippets across the breadth of your video library, giving very detailed access to all the material you accumulate. They could in effect build their own video. lol - maybe I'm making an impossible work project with this last suggestion. I suggest it because I absolutely see your efforts producing the quality and detail that is sure to satisfy Tesla researchers. After all, you are entering a rapidly expanding market.

[@TwoBitDaVinci]

we're going to digest this awesome quote, and we'll keep in touch with you going forward!

[@pacsmacks7142]

I love this channel already. 3mins in and I can’t even stop thinking about how amazing it is for someone to not only get all this information but to make a 21min video on it. Haven’t watch the full video since I’m super tired from work but definitely will watch the rest later. Amazing work and content keep it.

[@atomicsmith]

I'm not sure about your advice to not use seat heaters. They draw only a few amps, but can improve comfort greatly. The best advice I've seen is to run the cabin heater until it's comfortable, then turn it down or off and then leave the seat heaters on to stay warm...

[@TwoBitDaVinci]

Totally I think that’s personal preference and honestly you can try some trial and error read your power consumption meter and see how it plays out! Share what you find

[@Ingineerix]

I concur. The seat heaters are nothing in the scheme of things. You'll save more power turning on the seat heaters and lowing the heat temp setting by 1 degree.

[@gnagyusa]

Rel life numbers: I bought a Model S in 2013. I got about 265 miles on a charge. 6.5 years later, I get about 259 miles on a full charge. So, the big range degradation story is a myth.

[@TwoBitDaVinci]

That’s fantastic data, thanks for sharing!

[@Smedleydog1]

Do you charge your car to 100% and discharge it to say 10% to get maximum range? Or do you charge to 80% and discharge to 30% as stated in this video? I'm just wanting to understand how much of the battery pack's power reserve is used to get the range you state. Thank you.

[@karenrobertsdottir4101]

Superb video - I've never seen you before. But very well done. Might have been worth mentioning that the Model 3 has the batteries pre-attached to the cooling ribbon to aid in assembly - it's like a machine gun's ammunition belt.

[@TwoBitDaVinci]

Yeah not sure if we were clean on that, but thanks for the info!

[@paulcalmond]

Karen Pease I found the battery cooling to be an interesting solution but wonder about the coolant system only having contact with a small percentage if the cell, it seems to rely heavily on the "thermal paste"

[@dzerres]

@@paulcalmond Actually it looks like it has almost half of one complete side in contact with the cooling ribbon- more than I thought it would.

13:35 The AC-DC Inverter image is an image of a clutch friction disc. I am not following the logic behind a mechanical torque transfer part having any relation to an electronic part.

[@jacko101]

Also, the pump image is an image of a Turbo not a water pump.

[@Jayeeyee]

​@@jacko101 If you're referring to the "AC Motor" image, that's actually an alternator. "Electronics" is just a computer motherboard. TBdV needs better stock image skills.

Please, energy density in Wh/kg, not W/kg (power density). How can neophytes understand if everyone makes the mistake? I'm sorry to be aggressive but I'm annoyed everyone makes this mistake, even this pretty good channel! You cannot confuse these units talking about batteries, it's soo disappointing and it's not a small mistake, especially if this video is designed for engineers. *Great video anyway* :)

You have created the most succinct informational video I've seen to date about the current battery technology applicable to motorcars. There's a lot to learn regarding Lithium battery technology, and it's clear from your two-part video presentation that Tesla and Panasonic are worldwide leaders in the evolution of battery technology and electric cars.The future is promising, and it's exciting to be a small part of it.

Dual motor, big battery, and enhanced autopilot. I went with the 18 inch aero wheels to soften the ride a bit. I don't care for the looks of the snap-on wheel cover, but the alloy wheel under it isn't bad looking. I'll snap on the covers when doing long distance driving. Really looking forward to saying goodbye to gasoline, oil/changes, transmission/fluid and around 2,000 other moving parts subject to failure. I appreciate the tips on charging, your work gave me a better understanding of battery health! Thanks!

[@olsonlr]

I believe you spent time on this. Excellent content. Subscribed

[@coorbin]

I have a 2018 Honda Clarity PHEV and I'm loving it. Since buying the car (used) I've made about 20 trips, the majority of which were to work and back (23 mi each way) and my gas engine has only turned on once to do a "System Check" (a routine process to make sure it's working well) in the past 2.5 weeks. I have 283 miles of range in the nearly-full 7 gallon gas tank. I'll post back when I have to actually visit a gas station and fill up. :D I feel like Tesla is largely responsible for pushing manufacturers like Honda to make EVs and PHEVs.

I’m trying to keep my charging at no greater than 80% on a somewhat daily basis. Not necessary to charge every day, but keep plug in when at home. It will be interesting to see over time what effect this method will have on the battery life, as far as degradation. Had model 3 for less than a month about 770 miles so far. I’m using the app TezLab so my car data is being collected.

Do you have any safety information about the hazards and long term health effects by Electromagnetic Radiation from E.V’s.

[@miguellopez3392]

the only radiation that comes from an EV is heat and EM waves from the AC motor (gas cars also produce radiation from spark plugs, alternator, and combustion, going to the beach will hit you with 1000s of times more radiation then being inside the car.

[@nimblybimbly4002]

When people are talking about lithium reserves they're not talking about lithium stacked in the back of a warehouse somewhere. That refers to all of the resource that is economically feasible to extract. I'm not saying that's an issue to worry about right now, but the way you mentioned it in your narration made it sound like there's lots more to be had somewhere. That's not the case. 18:35

[@sjh7132]

After watching part 1 and part 2, this seems more like a Tesla commercial than independent research. This seems especially evident with some of the statements about completing technologies. For instance I've never seen anywhere near a 50% loss in range of my Bolt due to cold. And I grew up in Wisconsin, and started our gas car in -50F temps at least once a year. (With no block heater.). There also is a lot of 'Tesla does it this way, that that's the best', without weighing the advantages or disadvantages of the various approaches. I also doubt the the battery design in other cars is based on 'what room was left over'. I found this interesting, but I feel like I need to watch videos produced by the other manufacturers to get a balanced point of view.

[@marlaw8389]

You deserve much more subs! Nice Vid.

[@TwoBitDaVinci]

Thank so much! We have a lot more planned in the coming weeks!

[@johngilbert5326]

I ordered a Tesla Model 3 Standard Range (220 mile) through a Sales Office on Friday. I received the online invoice and it said I had ordered a Standard Range Plus (240). I called my Tesla representative and I was told they are basically the same car minus the auto pilot and they lock down the charge capacity to 220 miles. So they do have computer toggle to do such things on Model 3 's with the Standard Battery. This video did clear up for me the difference between the Standard/ Standard Plus battery and the Long Range Battery. Thanks!

Yes good point, sorry for the mix up there

[@MasterYoshidino]

BMS appears to be overhyped in this video. This is common as dirt in batteries. It's why cellphones don't spontaneously explode when given odd extremes like high current recharge but in a hot environment they slow down and in a common hybrid/ev the system will protect the batteries from reaching an event that can cause a fire. (overcurrent protection is why phones don't catch fire when left overnight while charging)

[@TwoBitDaVinci]

yeah, but your phone BMS isn't monitoring 4000 individual cells. So can be both as common as dirt, but especially good

[@MsSomeonenew]

BMS systems are common as dirt now, but the difference between stuff in regular appliances and the really good stuff is night and day. In particular your cell phone or power tool BMS has absolutely no problems letting the battery die within the year, but manufacturers who guarantee a 10 year life span need to play a whole new ball game.

[@Alexlfm]

The BMS on the Tesla isn't nearly as advanced as the cell phone in many ways. It does NOT manage the charging of individual cells, rather only modules, and the only balancing being done is with bleed resistors which is wasting energy and rather crude (and this is done on the module level). However for the application this is normal as it is not possible due to cost to do individual cells. That said it is not any different from any other car on the market. There is nothing that is at all special. The module board takes care of itself and then just reports to the BMS. The main BMS is not doing the individual balancing. Also if you have a bad cell, the entire module still has to be scrapped. A cell phone with multiple battery packs actually manages the charge to each of the batteries and they are managed at a truly cellular level. The Tesla BMS does not do this They are completely different things.

[@Arcona]

The Bms is monitoring each parallel set, not individual cells.

Excellent and informative videos! You guys should receive some sort of award from Tesla. If you have additional parts in this series, please also address the charge retention issue of these rechargeable batteries in EVs. Unlike gasoline cars where no one expects the fuel would evaporate after a long idle time, EVs have this unique issue of losing range in idle, just like an iPad that is in idle or even turned off. This prevents people from parking their EVs in the airport unplugged for a long vacation. I think this is an important and overlooked issue of EVs. Teslanomics actually has a video comparing the phantom battery drain of different Tesla models, and Model 3 ranks the worst with an average loss of about 12-15 miles every day which eats significantly into the efficiency of the car. Most importantly, a model 3 can end up with a permanent battery damage if left unplugged and unattended for a long period of time, which is highly undesirable.

The thing that bothers me a bit is how he calls it "Tesla's battery" all the time, as if Panasonic isn't doing anything. Panasonic makes these batteries in the Gigafactory. They share the Gigafactory, with most of the space being for Panasonic. It's Tesla owned of course, and Tesla is a client for Panasonic, but it doesn't mean that Panasonic can't just get other clients, as well.

[@av8rshane491]

Very well made video. I want to know Tesla model X 2017 will have the same battery management system as I believe this is a game changer and a big difference between other car manufacturers and Tesla can some one share a video or explain what’s inside Tesla Model X Batterie pack?

[@Satsumasable]

Hi, I was wondering if you were able to help. I am currently doing a uni project regarding an electric vehicle and the tesla data you produced regarding the battery was extremely useful. I was enquiring to see if you had a website for the battery recommendations stated between 7.52-8.45 of this video. Many thanks, Ollie

Check out Battery University, they have some good content. Cheers Ollie!

Got no problem starting my diesel when its -40 But i would rather have a petrol when its that cold because some diesels like our X trail can not produce enough heat to warm the car when its that cold, but my A4 2.5 can. Sure i know there are solutions, but I would rather have a petrol car when its winter. Then i don't have to remember to mix petrol and diesel when i am filling our diesel cars. Don't see myself owning a Tesla or a electric.

[@davidellis279]

WinnyJ1. Mixing diesel and petrol together to prevent it freezing in winter, I haven't used that idea since the worst winter ever in the UK in 1962/3 when if froze for 12 weeks solid. Since then the wax which used to cause the gelling problem has all but been eliminated from diesel fuel plus additives are added in winter fuel. If you live in extremely cold climates and diesel gelling is still a problem then just add 25 per cent Kerosene to your fuel which will solve the problem, you don't see commercial airline jets having problems with freezing fuel at -50dc when at 40,000 ft but they use 100 per cent jet fuel which is basically Kerosene, putting petrol in one of the high pressure direct injection Diesel engines is Not a good idea because petrol is a spirit and has no lubricating properties in it so may cause very expensive damage to the fuel injection system.

[@GeFeldz]

15:55 "In freezing temperatures, a lot of petrol cars won't even start" - which petrol cars are you referring to? Virtually all of the car manufacturers test their cars in arctic winter conditions and make sure they can be relied on. If you keep the battery of your petrol car charged, you should be able to start it in extremely cold conditions. A lot of car manufacturers test their cars here in the northern parts of Sweden, especially in the arctic winter. Sometimes the temperature can drop to about -40 degrees F or C (at -40 the two scales intersect), however the temperature can be below -20 degrees C/ -4 degrees F for weeks at a time in the winter. Northern Sweden and northern scandinavia in general is the land of great contrast. -40 degrees C/F extremes in the winter and almost 40 degrees C/104 degrees F extremes in the summer. Usually it stays between -30C/-22F in the winter and 30C/86F in the summer but the extremes do occur and once every few years there can be extremes of below -40C/F and above 40C/104F. Most people use electric heaters in the winter to warm their engines for significantly reduced wear and significantly increased comfort, but the cars are engineered to start in pretty extreme cold.

[@bistrovogna]

The starter battery, especially if a couple years old, could easily die after a couple cold starts in -40! Also, diesel are worse than petrol in those temps.

[@shaneebahera8566]

@@bistrovogna you can get your battery tested for cold cranking before winter a lot of place here in the UK will do it for free. Diesel engines will have a harder time starting but with modern engines we are talking of a just a couple more turns before it starts

[@Plisko1]

A lot of people in the US drive old model cars. Still more people in the US don't pay a lot of attention to maintenance of their cars. Both of these conditions create a lot of petrol cars that don't start in the cold. We can't refute this point by assuming all petrol cars are modern, tested in Sweden, and fully maintained. We simply need to look at how many petrol cars a year call for roadside assistance because they wouldn't start in the cold.

[@brownmold]

I agree with GeFeldz. I've never experienced a modern FFE not starting just due to the cold. Quite simply, the statement is offered without evidence, or any real meaning. How many cars is "a lot?" "Freezing temperatures?" Which model cars can't manage under zero degrees Celsius?

Nicely done many thanks

[@solarstacks]

FYI on old 2012 Tesla S 85 we had 1 cell go low. The car would not charge. We had to drop the pack and bypass that one cell to get it all working and charging again. It's so goo the newer Tesla have over come that issue.

I like the idea Tesla Engineers start from scratch if need be instead of piggy backing on existing technology to save money. This is costly but can have big leaps forward that were stopping other car companies.

[@LoneWolfZ]

You talk about an "inefficient resistive heater". Resistive heaters are close to 100% efficient. Just FYI :)

[@davidsuzukiispolpot]

True! Lol

[@Tore_Lund]

Does anyone know the efficiency of the model 3 motor? Being a PM motor, it should be over 90%??- Looking forward to your life cycle analysis, i.e. how long you need to drive your Tesla before you've emitted less than sticking with your petrol car. About winter driving: 4WD is really not needed and is an extra penalty when fighting reduced battery capacity. Keeping the battery warm when you need it, is simply a matter of programming your charger to finish when you need the car for your morning commute. That also makes it charge at night where electricity is cheapest.

[@TwoBitDaVinci]

Yes we’ll definitely get into that

[@TroyeWelch]

Tore Lund those are all really good points.

@ that's my point though, you can get unlucky with ice engines same as anything else. Honestly though if that guy that went through 3 engines is the worst thing to happen to an electric vehicle then that's damn good.

[@lewtenant_k]

I'm pretty sure the Nissan Leaf has at least the option for a heat pump in some years. This video implies that only Tesla's have heat pumps.

[@TwoBitDaVinci]

Sorry yeah we didn’t mean to imply that. Just speaking about Tesla

[@loungelizard836]

Yes, Nissan put heat-pump heaters (like a reversed AC) in 2013 and above. 2011 & 2012 used resistive heating which can only be 100% efficient at best (1 KW of electricity gives 1 KW of heat). Heat pumps allow efficiency far above 1:1!

[@edwindewit8349]

Lounge lizard, efficiency can never be >1. What you mean to say is that it costs less power to transport heat generated with even more power. e.g. you can heat air with a 3kW heating element but it will take maybe only 600W to move it around.

[@petrvalkoun4539]

Edwin de Wit speaking of heat pumps, you can define efficiency as heat output divided by electric input, which then produces efficiency of 300-400%.

[@calvindibartolo2686]

@@petrvalkoun4539 that's not how efficiency works LOL You're right though, heat energy can be measured in watts, but it's nowhere near 300-400%. It's claimed 100% efficient because 100% of the energy that goes in comes out as 100% heat (because we *want* heat, whereas normal electronics heat is undesirable, which detracts from efficiency), however it also introduces wear on the heating element, which takes away from efficiency.. However that heat is then dispersed into the air which can only take so much so quickly (heat capacity) and can only transfer so much so quickly. If you hold your hand to the heater to warm it up, you'll get near 100% efficiency, but any time you add a medium to transfer heat through before it reaches your end target, you're losing heat to it, and air is one of the worst mediums to try and transfer heat.

[@stanislavkogan]

Claiming that "a lot of petrol cars won't even start in freezing temperatures" is a lie. Very FEW cars actually have that problem and overwhelmingly due to poor maintenance.

[@CtrFelix]

Well, if the petrol or diesel quality is poor, it can freeze in your tank. So no matter how well maintained your engine is, the car will not start before you heat the petrol.

[@youandiryan]

My fossil eating car ,my little 2016 Toyota corolla has never had a problem starting in extreme cold. I'm from Alberta Canada. Where temperatures can drop to - 40 Celsius (-40 Fahrenheit). It will start even if I don't plug it in.

[@freshcharge]

Yea ironically the battery is usually the reason a car won't start in the cold. I know batteries don't perform well in extreme temperatures. With Lipo batteries if you heat them above 110 degrees the voltage will go up and discharge faster.

[@youandiryan]

@@freshcharge yeah usually in a gas car they use lead acid batteries which are more resistant to cold. I mean they still get affected. But a lot less than lithium. If a lead acid battery is charged. It can withstand -80 pretty easily. But if it dies in that temperature the liquid in the battery will freeze solid. And will be damaged permanently.

[@TwoBitDaVinci]

Interesting, I'd recommend checking around on KZbin for something like that. I'm pretty sure Tesla doesn't support it because it would be degrading the batteries without any mileage. But Guys like Jehu Garcia, and Rich Rebuilds might be good sources! Check out their sites, and if you find anything interesting, please let us know!

[@sytechtv5569]

Really enjoyed both videos, great job..

[@Alexlfm]

No. This will likely never happen as first, it doesn't make sense. Your car won't have any charge in the morning when you'd need to use it. Also the amount of energy that you could get out of it would be limited. Secondly, and most importantly, charging the battery is NOT a two way system. In fact, it is specifically designed to be one way only. There is several stages of voltage conversions and regulators that change the voltage from a higher voltage low amperage to the opposite. This system does not function in reverse. Secondly the power that goes to the motors is also regulated and converted from DC to multi-phase AC. This is much higher then what is suitable for household use. Without building a system specifically to export energy this is impossible to do. You can't just directly hook up the batteries either as A. you'd have 24volt DC power and B. you'd lose all of the safety and battery control systems.

[@louisemorton8154]

The Nissan leaf allows you to use the car battery as power backup to the home. It does make sense if all I need is up to 10kWh in the evening to time shift my usage.

[@Alexlfm]

Louise Morton Supposedly. Too bad nobody outside of Japan has it to my knowledge. I know with the first leaf they did a trial with it in Japan and had a massive 4000 homes... They installed extra equipment on the car for the purpose, you need equipment installed (almost as much as a powerwall at your home) , it’s stupid and dead in the water. At that point you’d have put in all the expensive parts of a solar system, you might as well hook up some panels. You can’t just backfeed through an outlet you need inverters, utility wave matching, interconnects, etc. this costs thousands. As Tesla IS in the solar and backup battery business, and the costs make this idea stupid to begin with, I don’t see it happening. As I said, outside of Japan I am not aware of any real leaf installation. That should show how well the idea works in practice.

[@frankvillani8701]
