SAFT have indeed been around since 1918 and have built a reputation for high quality batteries in the shipping and aviation industries. They are based in Bordeaux where the R&D centre still is. The US Navy are a big customer. In 2016 Total bought SAFT and went into partnership with PSA/Stellantis to build a pilot plant and two giga factories, one in France, one in Germany to supply the Opel plant. The pilot plant is 60 km south from where I live, it opened last year and can provide 8 GWh a year. The joint company has the unimaginative name of ACC (Automotive Cells Company). Mercedes joined ACC last year with another couple of billion Euros of investment planned. The claimed technology improvements mentioned here follow the recent announcement of a 'pure' EV platform coming from Stellantis Group...when? who knows but the two announcements do seem to fit.
It's about time. It's been at least 6 hours since the last "game changing" battery was announced.
I just wish one of them was actually practical and made it to market.
Catl condensed matter cells entering production by q4 of this year at up to 500wh/kg is real.
Catl just formed a joint venture for electric air craft. Those cells will power the prototypes.
Nio and welion has the 150kwh pack in production and available now. Semi solid state pack weighs 44# more for 150kwh capacity vs the current catl 100kwh nmc pack in the same case. Cost is prohibitive though, rumored at nearly 40k just for the pack. 🤔
@@4literv6 Also worth noting that CATL's battery is actually claimed to be cheaper than current Li batteries.
LoL. Well said
@@davidcolin6519 indeed, very exciting imo to see the world's top battery producer boldly saying a 500wh/kg battery is entering production later on this year. Then actually form a joint venture for electric aviation! I believe catl will do what they say&shouldn't be ignored or dismissed.
Also seeing as they are teslas largest single cell provider currently. That could mean some interesting time's ahead for tesla high end model's.
Like gen2 roadster and maybe even semi? Imagine a 700-800 mile semi that charges in 30mins or less.
Or a gen2 roadster lighter than a model 3 performance is, but with plaid hp&better aero. Watch out rimac nevera. 😀👍🏻
@@4literv6 I think that you're jumping
the gun a bit here,
Just because CATL supplies Tesla doesn't mean that Tesla is going to be favoured.
In fact Geely's Zeekr brand will be the first to have delivered units and, although Tesla has pu t in orders, there is no guarantee that they'll perceive favourable treatment.
And although Tesla has made a name for itself by working on efficiency by using aerodynamics and lightweight aluminium casting techniques, I am sure that there will be many companies clamouring to get these batteries.
In fact, seeing as CATL has multiple development contracts with multiple manufacturers, I suspect that production will go to manufacturers who are best placed to promote the wonders of CATL technology.
Under the circumstances, does that even begin to describe Tesla?
My impression of Tesla is that it appears to be entirely built around singing the praises of Elon Musk. You can certainly correct me if I'm wrong, but what if I'm wrong, but the impression is right? How far do Tesla drop down the list of clients? Obviously they're already behind Zeekr/Geely, but there are plenty of Chinese automakers which have just as enviable relations with CATL, but which don't have an egotistical maniac at the helm.
The IBIS battery system could be really handy for refitting old gas cars to EV. Being able to use smaller modules allows for more choices on placement in the car and getting rid of the inverter and charger is also a big deal.
Packaging the batteries is still an issue for an existing car. Splitting the batteries locations will cause issues with the loses between each group and the inverter caused by the varying length of cables. Creating 3 phase from batteries is nothing new. And frankly does not even require the batteries to be separate from each other. What they are doing is creating a stacked inverter array to create three signals.

@@davefroman4700 Renewables use AC to remove power losses from distance. These modules tend to do this, and as such, it should be less of a power loss from distance.
@@ronaldking1054 Its DC from the inverter to the battery. You cannot put AC current into a battery.
When its in a production vehicle its real and can be evaluated. Until then it's vaporware
vapourware = eye candy (and even distractions) for the investors and EV community
I call BS on this one. One big inverter/charger or a bunch of smaller ones should not any significant difference. It's like the central inverter/charger vs. micro-inverters in PV systems. They exist. Their main advantage is where you have PV panels with a layout where some are in the shade part of the time.
What about solar panels with integral grid tie inverters in each separate panel
That's the way I see it too. Nothing revolutionary here.
There will be new batteries every year for at least the next decade but will one of them be from Setllantis? We shall see. Legacy auto does need to innovate to compete with Tesla and Chinese brands so we might see some good ideas from them. One interesting development from IBIS might be that it could be serviceable. It would be nice to be able to replace just one module rather than replace the entire pack.
No. The capacity of the Sodium-Ion will be increased during the next 5 generations. All the other "breakthroughs" will turn out to be blabla.
@@chillfluencer That’s cool with me, we only need one of them to pan out to get better EVs.
It may be like Nio which allows for battery swapping.
yes, if you look after your car, it will last decades with this IBIS concept, even if the battery chemistry is not available anymore. it juts needs to be compatible at the plug of the module.
you could even throw out an old weak module and upgrade to a newer module with higher energy density and better charging speed.
it would be great if stellantis and VW could agree to the same battery format and plug/interface.
This battery tech is similar to solar panel and micro inversor
At the same time, Stellantis would funnel millions into pushing back on EV and emissions regulations
In Germany the word for juice is "saft", a good name for a battery-company. 👍🔌🔋
Good one, actually SAFT stands for « Société des Accumulateurs Fixes et de Traction » in French or Fixed and Traction Accumulator (battery) Company in English
Then I had orangen saft with my breakfast.🥵
That's Norwegian for squash too, look up "saft ZERoh" for a laugh
Apparently whenever a car maker is about to go bankrupt they suddenly have an epiphany and discover magic battery technology that will be ready in just a few years.
"Meanwhile, buy one of our ICE cars."
ICE is proven tech. It works. We have to face the facts.
Sam. I have watched your channel for a long time and enjoy it. But every few weeks we see a new revolution in batteries that are going to change the world. True, our original 22kW Zoe from 8 years ago has more than doubled its capacity in that time. We have Kona now, great car. But will this revolution in batteries really happen. Not every few weeks I don't think.
It sounds like they've just moved the inverter/charger to the battery pack, so haven't actually saved any space or eliminated them as they say in the promo video.
I'm thinking chemistry is less of an issue as each battery module will contain its own micro-inverter. So I suspect there will be different versions of IBIS modules with different chemistry, but they will "present" to the vehicle (or whatever application) as the same. This could also future-proof vehicles as you'd be able to swap out modules with newer/better ones.
Maybe.
exactly. this would even theoretically allow upgradeability. buying the car with a cheap set of LFP modules, maybe having the space to add two modules later, adding two LFMP modules later. removing two LFP modules and add two solid-state modules. using old modules for your house energy storage system.
the chemistry of the IBIS battery is not known because it is a concept that is independent of the battery chemistry. so, in my eyes this not concerning but a win.
the real wonderful benefit is the integration of the inverter in the battery modules. that allows flexible scalability, upgradability, mixing of different modules with different chemistries and old and new modules. and what is super cool, is, that you can theoretically use such a module for home energy storage with the already integrated inverter. that allows an easy 2nd life usage.
brilliant. the MEB modules of VW are already very good for occasions where a battery needs repairing and 2nd life usage. but the stellantis modules with integrated inverters are next level and could be a dream for scalable home battery systems.
The Ibis battery, that would be successor to the bin chicken battery and precursor to the flying pig battery?
AC charging is fine for local travel. What do they say about Rapid DC charging?
Yet another great innovation without even a prototype. Did they just copy Toyota's playbook? If I had a free dinner for every new battery announcement, I would never go hungry again. Smell space? They should buy a Dolphin from BYD and take it apart, if they are stuck for ideas. Prices in China are reported as 16,700 - 19,600 USD, while others report even lower prices.
More ta come watch ur weight
Well you could turn it into a drinking game, but I doubt many peoples livers could cope! 🥃🍷🍹🍸
There could be a substantial market for small and cheap EVs that may only have a range a bit over 100kms. Many households could getaway with one larger car for long distance driving and a small EV just as a town car. If it is small for parking and very cheap to own it would sell.
or buy a low range car where there is still space for another two or four modules and after two years you decide to upgrade.
In theory, it sounds like they can save weight, which is very important for an EV, and save space, although, instead of just ONE box you actually have to have a NUMBER of inverters and converters as you have one for each battery.
If all these components were cheap and abundant that would be true, but they are expensive and we have already seen the effects of components shortage.
I would say you add more complexity and a tremendous amount of cost, lithium batteries are expensive but these components are even more expensive, and filling the car with them at this point in time is not cost efficient, maybe in ten years, at best seven to eight years.
You also have to take in account the longer high voltage cables that has to be run from each every battery to the motor/motors.
I have a hunch the technology is a spin off from the citroen oli concept vehicle. They possibly have the chassis and personalization parts and low weight parts ready. I think with this modular battery system, different capacities can be offered. I think these batteries will not shine in the performance department of the vehicle but provide a valuable solution to inner city driving solution. Wouldn't be surprised, they will create a system of modular batteries with integrated power system, that can easily be swapped between mobility products, such as the next generation amis, olis, scooters, powerful ebikes, and perhaps modular home powerbank/power wall systems. So I think they might have something smart going on. If every module was roughly 3 Kwh hours, one module could run a home appatment for a day for most people, opening up a whole new market beyond mobility devices with ibis. I think, that although it doesn't make direct sense to have this system in a car in terms of space and efficiency, for a cheap car, for a future energy solution for the future in curious where Stellantis will lead us with this for future city energy solutions. Citroen has historically often been innovative with new technologies in cars over the decades. How do you combine luxury, comfort, and innovation?
It's analogous to the microinverters used on some solar panel systems rather than big inverters fed by string aggregators. In the case of panels, it sometimes makes sense (even thought the microinverters are less efficient than the big ones) because of better response when panels get radically different illumination. You don't have that motivation with battery banks, but who knows? The big silicon carbide chips Tesla uses are the efficient approach; do those scale downward to pack size?
The cooling of the inverters will also complicate matters in the pack. If much heat is generated from the inverters, it will make the pack overheat when fast charging or at high demand (rapid gate). Also the numbers of silicon carbide chips will be much higher or if not using silicon carbide to save on cost, it is then a low power solution. This is likely why they are planning on using this on compact cars.
It will make it to production in 2032 when the rebates expire.
Rebates?
Sounds like they will be out of business before this and Toyota are on top of their battery developments.
Only 1 year back Stellantis was saying no one wants EV's and they can't make a profit on EV's. I wish they would just shut up and deliver on their new IBIS Battery tech!
Those 'completely independent modules' raise an obvious question: how is battery voltage regulated during vehicle operation? It presumably doesn't just change continuously. So, there is a lot more fine grained detail that needs to be disclosed at this point before it will be possible to judge whether this new battery has merit or not.
What chemicals are used in the "brine" for direct lithium extraction (DLE)? Is this another form of fracking?
Two things, 1st is when, 1 year,2, maybe 5?, 2nd is, how does it operate at 25-30-35 below 0 C? If theres any fear that a car is going to quit and freeze up when its cold, its not going to sell in Canada.
I've just returned from holiday with my friend, he has a Fiat 500E, range according to Fiat was supposed to be 160 plus miles on a full charge, best we got was 120, and a knightmare to find charging points, once we were panicking, down to two miles. And the cost of charging has quadrupled since he leased it. Works out it would have been way cheaper to use my diesel car, an Audi A3 over the 800 odd miles we covered
Fiat 500E prob doesn't have a liquid cooled battery... which will kill its lifespan and disappoint in hot/cold weather.
That said.
Tesla is not Fiat.
They can't afford to produce lemons, so they have to be far more reliable.
You have realised what many will eventually be forced to.
From your description sounds like each small battery module has its own inverter and charger on a single PC board and sharing many components but also dealing with much less power (because of the small module) . Presumably economy of scale will kick in and make it cheaper per board.

Any new battery technology where-ever it comes from is good news. Somehow I think the Japanese might have a surprise for everybody in the following years. The current Li-Ion was basically brought to market by the Japanese (while of course a lot of the research was made all over the world).
Put faith in surprises into a specific industry that dragged its heels for decades and manufactured FUD as this world is already experiencing climate collapse.
doesn't follow that anything comes from that source...
Evening mate
I feel like this might charge very slowly without the inverter/charger. It will create, strictly charge at home cars, which to be honest is all anyone needs but might be a hard sell outside of Europe/second car market.
I am guessing that it is a computer system similar to those used in stationary grid storage systems that keep grids stable with high levels of RE in them, sometimes called a "virtual powerplant".
Computer industry once had separate hard disk controllers of many sorts and raw disks. Eventually as electronics got cheaper and more integrated the whole controller was put inside the drive and the abstraction moved up to the host controller interface. This was called Integrated Drive Electronics or IDE also known later as PATA for Parallel (PC-)AT Attachment a retro naming when SATA the Serial evolution was unveiled.
Also from computer engineering came RAID, the Rapid Array of Inexpensive Disk, where the parallel usage of massively produced standard HDs with in integrated electronics were able to far surpass large complex and costly specialty build drives once used for high performance.
From the engineering point of view there is a design space to combine parts into functioning systems and tradeoffs to be done.
The same way microinverters might eventually dominate the solar PV landscape "rightsizing" electronic controls to panel area, there might me an equivalent compromise where rightsized inverter-charger per battery modules might make sense.
Might. The devil is always on the details (and the timing). The idea is elegant and deserves further consideration and analysis.
SAFT is no delusional newcomer to battery business.
Saft is real company. They built the charging systems for the lithium batteries for the Boeing 787
Oh, the one that had so much trouble!
Let’s see it in volume production for cost…
Everyone has new batteries that will revolutionize everything these days. I’ll believe it when they’re in a production model.
So it could be doing a Nissan & Toyota 🤔
It seems like the inverter is simply integrated into battery modules and, therefore redundant. Tesla does this in the "penthouse" (forward end) of the battery pack.
So instead of doing this once. Its done for each module (Tesla doesn't use modules anymore) begging the question how this improves anything.
Rather dubious that this reduces overall weight compared to Tesla structural battery.
Sounds great 🤞
nice design of prototype
Similar innovation to micro-inverters on solar PV systems. They will be more expensive because there is simply more hardware required. Plus lower volumes being produced.
Interesting. Curious how their prototype will go.
They should sort out their battery charging and monitoring system first. 😉
It also looks like a safety improvement.
It's a SAFT battery even if Stellantis are crowing about it. If the finance is there I'm sure that SAFT could manufacture the battery long before Sam's predicted date. And, only if your having problems with math, does a battery pack that eliminates some EV engineering costs by simplifying and integrating/subsuming charging related functions in the pack somehow fail to get an automaker closer to a break even point on reasonably priced EVs.
Sam confusingly ran together cost savings that follow from fundamental redesigns (or elimination) of vehicle components and cost savings resulting from efficient mass manufacturing. The full cost benefits of a technical redesign are only realised when products with that new design are turned out at high volume from production facilities that are themselves a marvel of efficiency but that doesn't mean that redesigned components fail to realise any cost savings at all at an early stage in the scaling of production.
The limitation of what is being proposed here is that the fastest AC charging rates anywhere in this world aren't fast. Either buyers of vehicles are going to have to be happy with slow charging or SAFT will have to propose new standards for AC charging around the world.
reminiscent of micro inverters mounted to the back of solar panels.
Just wait till Tesla release their two smaller models which are in build phase as apposed to word phase.
Long AC wires have more losses so more copper is needed
I have a new revolutionary solar panel, I have integrated an Enphase micro-inverter with the solar panels.
So its like the "micro invertors" that sit on the back of some solar panels (instead of dc being shipped to a central invertor)?
nope. those are parallelized on output. the saft concept is to generate each phase with a string of microsyages attached to cells.
Keep hearing about batteries that will game changers. How about batteries that are on the market now.
As does all makers claims on their new battery!
That would be funking great
Everyone seems to have a magic solution just around the corner. Hope they are correct.
4m long, 400km+ WLTP, 25.000€ (without incentives). Build something like that and I'm seriously impressed.
The likelyhood of failure is much higher. The inverter should NOT be places inside the car. Its a waste if ressources there are more cars than charging stations. In addition every solarpowered house allready have an inverter. The future is the same like for cellphones.
We hear this all the time of companies with new battery technology that will revolutionize the EV industry but nothing comes of it.Battery technology is improving all the time but it is going to be years before any of them can be called revolutionary.Most of these claims are coming from the old legacy auto makers but they are all well behind Tesla and the new Chinese companies.
It still needs a terrin pin and a matable placky, in order to be a game changer in my book.
A good idea to make parts less accessible.
Given the efficiency of current solutions has been tuned to the max I doubt there is any room for any improvement. Cutting the electronics in pieces so it rides with the battery has more disadvantages than benefits. I would call this nonsense.
Microinverters? Is this the same theory as renewables using microinverters to reduce power losses over distance by keeping most of the car in AC rather than DC? The problem is that even in a renewable system, there is still an inverter, which keeps everything synchronized, but that is a function of trying to match the utility rather than control, I believe. Maybe Stellantis is claiming that the battery management system will be the inverter.
So many unknowns, I was reminded of Trump's 'Two weeks away' Health \policy. We were just told it would be so good. What was it again?
They could use solar pv ²" space of battery
Have not you noticed that vaperware is always the best that will ever be!!!!????
It looks like Stellantis will time the introduction to coincide with the robotaxi. Hmmm.
You gotta love Legacy auto. Now that they realize they're way way late to the EV game. They are now announcing breakthrough batteries that they don't have to try and stop people from buying EVs.
This is not new technology, this is old wine packaged in new bottles.
HSBC expects the EV penetration rate in China to reach 90% by 2030
Everybody follows orders there
It sounds too good to be true. Hopefully it is true and works as they say. Time will tell. Battery tech is going exponential on advances with so many manufacturers. That can only be a good thing.
Sounds like multiple inverters replacing one. Not sure how that makes anything better. Sounds like more weight and cost... just shifting it to the "battery" vs a single unit in the battery pack vs module.
Sounds like someone moving cost to a different column on a spreadsheet and claiming a price savings.

Is this Stalentis occupying media space with their supplier's advancements?
There’s a “game changing” thing everyday, yet the game still remains the same.
Everyday has a new battery revolution, been like this for years and is getting really tedious
The revolution WILL be televised! 😂
It's called the "hot air" battery...
Might be a good idea but just making them micro invertors is hardly going to "revolutionize" EV's. Makes for good headlines tho....
Yeah, I'd give them a score of 3 Toyotas out of 5 for likelihood this is mostly just PR
☝️🤪 game changer, revolutionize, incredibly low prices, no working samples, no firm date... 🤓 Here's my money
Only batterie making sense to Me is CATL's high density LFP, Which is real AND here..........Paul
Not even the so called revolutionary 4680 battery cell is revolutionary like pronounced on elons battery day. The more important question is, is the thermal management also included in each pack unit?
This is bad idea, my geely geometry c needed inverter replacement' it took 20 minute to replace it. Now the job wheel need to un plug the big battery.
You couldn't recognise brilliant technology if it bit you in the face. Even though having read this article, it's gone completely over your head
Developments like these will be coming fast and furious from all directions. It also points to why thecTesla valuations are smokevand mirrors becaise they assume that it will maintain it's initial lead which is ridiculus
Stellantis has seldom done anything as good as they say unfortunately... Let's hope this might work out for them if they can hold out that long....
i think that concept is fantastic. they can also sell these modules at the open market for home storage.
Every week there will supposedly be a new battery that will charge the world. Where did I hear that before? Ah yes, last week
I take my earlier comment back. This seems like a genuine attempt at a step forward, not a “Toyotaesque” pack of silly lies.
At least they're not chasing hydrogen.
Sounds like hype
More pie in the sky.

I am an electrician in the renewable power industry, and can tell you that combined inverter and battery chargers have been commonly used in the renewable power industry for over 30 years. It is not “revolutionary .”
All engineering and design choices are a matter of trade offs for cost, size, weight, reliability, and efficiency. Having separate dedicated inverters and chargers allows for better efficiency and performance of each unit that will be weighed against the trade offs and benefits of combining them in a single unit.
While combined inverter and charger units can provide a somewhat more integrated system, it also requires a different design approach to the charging system.
The inverter takes the direct current (DC) power from the battery, and converts it to 3 phase variable frequency alternating current to drive the motor/s. In order for it to work in reverse as a charger, it has to first be designed to do so, then disconnect from the motor/s, and be connected to an alternating current (AC) power source that matches the inverter’s voltage output. Then the inverter/charger can convert the AC input into DC output that can charge the batteries.
Stellantis is just building the charger and inverter into the battery modules. Lets be clear about that... there is no way to actually get rid of the charger and inverter. The batteries themselves are still DC. This is not an improvement. The lower voltages in each pack make the functions significantly less efficient and the multiplication of parts (every module having an inverter-charger) is more expensive and less flexible. This makes about as much sense as a hole in the wall.
Ty for ur very llkely possible foment u could be right I’m jus not smart enough to know any better
"microstepping" with multiple LV stages has some advantages. much less filtering, for example. lower voltahe parts with much slower switching, makes for less expensive parts, more efficiency. its a bold concept that needs quite some cost optimization.
@@skataskatata9236 The electronics will be individually cheaper but not when you multiply by N packs. The aggregate will be more expensive. Voltages and amperages are lower, certainly. Efficiency is lost by running at lower voltages, however. Switching speed still has to be high though because that also directly translates to efficiency.
The way to think about this is to consider... say look at a Munro tear-down of a Tesla motor-inverter module. There really isn't a lot in there. The power switching electronics are a bunch of IGBTs and a few big capacitors and/or inductors and that's it. No space is being saved by moving that stuff to the battery packs.
On the charging side it is worse because each pack has to deal with line AC... i.e. 240VAC. Or at least 120VAC (but most likely 240VAC). The only difference there is that the charging amperage is divided by N. But again, this is being compared against the in-vehicle charger which again is not that big of a beast. I just don't see any advantage.
There are plenty of disadvantages. The main one is that, as other people mentioned, battery chemistries are progressing at such a high rate does VW really want to integrate extra junk into their battery packs? The one piece of equipment that is undergoing very fast, forced evolution? Every chemistry change would require reworking the charger and inverter to some degree.
Its a huge mistake in my view. VW needs to make those packs as simple as possible in order to be able to update them as quickly as possible as battery chemistries change. That means: raw cells, BMS, and that's it. No additional complications.
@@junkerzn7312it is Stellantis and not VW 😉
I fully agree with that your take and had the same reaction when I first read the announcement.
On top of that it is my understanding that the 3 phase AC current the drives the motor has to be finely tuned for best performance. If it is the case, good luck to synchronize inverters from 24 battery modules.
I would also say the industry leaders (Tesla and BYD) are moving away from battery modules to structural battery packs so these packs will probably not be very efficient in Wh/kg compared to structural batteries
This system does not appear to be about the batteries and their chemistry at all. It will work with any chemistry.
The novel thing they are doing is in the battery management system. They are switching batteries on and off very quickly in defined groups and using that to generate a typical AC wave that drives the motor just like a three phase power supply would.
They won't need an inverter nor a charger as they are never converting from AC to DC and back again.
It will also save the 5% - 10% of energy typically wasted doing these conversations.
but they will sell these tiny cars at a big expense €€€€€€€€
May have to takea few days off, as i broke my ankle tripping over all the new battery tech there is
May have to also have to take a few days off, to get over the stink of BS. Toyota, Stelantis and others announcing new systems with fancy names, without even a prototype.
We don’t know much do we from information provided
So, IBIS Battery tech, is vapourware at this time?
