Good video, it's nice to actually get a bit more details about the battery tech as most people just see it as rocket science. The only thing I'd add is a bit more description of the acronyms, ie I'd mention that the 96S-108S stands for cells in series and the 1P is for 1 in parallel, as battery engineers tend to name the pack that way apparently. More cells in series raise the pack voltage, more cells in parallel raise the capacity level while keeping the same voltage so apparently this is the combination that works for them. There's a really impressive video from Lucid's Peter Rawlins describing their battery tech, it blows my mind how well a CEO can describe a product in proper details.
You make a good point, a bit more explanation of the terminology, etc., certainly wouldn't hurt. I'll keep it in mind for other videos going forward. I watched that video with Peter Rawlins, or at least the video I assumed you meant (Battery Pack | Tech Talks). It's very well done! Good homework for me 😄 Thank you!
@@siasek yes, that's the one. Master class in explaining nerdy things (I obviously have a weakness for tech related stuff so I was hooked in his tech talks). Another great channel for this is Electric Classic Cars. That said, I love your videos, short, informative, to the point and nicely presented!
I'll check out Electric Classic Cars as well! Yea, I enjoyed Peter Rawlins' presentation - informative and detailed, but still engaging. I don't currently have the badwidth for such high quality production, but I'm setting my sights high, so definitely appreciate the inspiration. I'm very happy that you get value out of my videos, it's great motivation to keep at it and keep improving 😊
Very nice to hear SAIC With the MG4 is in the very front of car batteries with the new One Pack Battery. I hope it one day can replace the battery in the MG4 from 2022
I think there is already a large market of battery or module replacement companies emerging, BMW i3 and Nissan Leaf are nice examples, I think MG4 will definitely be next in line in the near future. Fingers crossed!🤞
Please change the room and/or the microphone. It's too much echo. Very interesting content. I have got a MG4 since November 2022 and I have no idea how it works (but it really works great).
Oh, that's surprising. I just listened to it again both with and without good headphones and can't hear the echo, so not sure what's going on there. Glad you're enjoying the MG4, it's a great car. I'm having fun taking a closer look at the the tech that makes it happen 😁
@@siasek Echo is not the really correct word, in German we have two different expressions. It sounds like a reverbant room like a church. The opposite would be a dry sound without reflections which is better for speech, but sad for a chorus.
I see! I'll get a bit further from the wall and closer to the mic next time. I'm in a different environment than usual, so gotta test it out a bit. Thanks for the feedback!
Interesting semi-deep dive into pack construction, also interested in cell chemistry and BMS philosophy and details, good effort in a difficult information picture. 👍
Thanks for the feedback! I'm also interested in getting more info, but unfortunately it's not really available. At least I haven't been able to find it so far 🤷🏻♀️
Do you know if the MG5 carries the same battery technology than the MG4? I don't mean the chemistry, I mean the battery architecture and burn protection@@siasek
I think Blade and Onepack are comparable technologies in terms of durability. MG quotes a lifespan of 1500-2000 cycles, which is above average. I think with standard usage, the lifetime will be over 20 years, for taxis and similar high mileage applications definitely over 10 years. I wouldn't worry about durability at all. By that time there should be a large network of repair centers and even replacing modules with new ones is easier than servicing a modern internal combustion engine. 🙂
Very detailed deep dive. BYD always brags about their batteries. But if the one pack can achieve specifications close to the Qilin battery in a budget electric vehicle it is truly a game changer.
I'd love to get even more details, but I haven't been able to find any closer information.. I guess we'll have to see how the One Pack withstands the test of time. Thanks for watching! 😊
Excellent video which is, for once, properly informative and, what is more, based on fact, not opinion. I do have a question for you though; Seeing as SAIC and CATL are working together, does this mean that CATL's new Condensed Matter batteries are likely to be made available to SAIC any earlier? The other question also seems to be begged by the "Battery Swap" tech employed on this platform. Will those CM batteries be employed?
Thank you so much for the kind words on our video! You made my day! 🌟 For your first question about SAIC and CATL's partnership - I know they formed a joint venture called United Auto Battery System. The new Condensed Matter (CM) batteries from CATL are definitely exciting (I mean, 500 Wh/kg energy density, hello future!🔋) there isn't crystal-clear info on whether they'll be up cozying up with SAIC sooner rather than later. I'm also curious to see how that unfolds. 🤔 Regarding the Battery Swap, SAIC is putting its best foot forward in this space with brands like Roewe and MG getting on board. But, whether CATL's cutting-edge CM batteries will be the guest stars here is still under wraps. Though, let me tell you, with their high energy density and semi-solid state with condensed electrolytes, they would be the perfect fit for the battery swap game. ⚡ Let’s not forget - SAIC has been dropping hints about making its grand entrance with a solid-state battery-powered vehicle in 2025. So, the plot thickens... Oh, and one more thing! SAIC, CATL, and some big names are thinking ahead and planning on integrating battery swapping and charging across more than 50,000 gas stations in China. So I don't have any definite insights, but it's definitely fun to watch, so I’ll be watching closely and post updates!
@@siasek Thanks for the in-depth reply. It seems that the Chinese have not only learned to make interesting cars, they've also learned to play the "teaser" game as well, and that also helps to boost interest.
It can definitely be a good marketing move. I just hope they don't learn from European brands (looking at you VW and Skoda) to release a teaser 3 years in advance 😄
@brendansheehan7714 Good question, but finding the answer is quite a challenge... the only thing I was able to find is this: MG4 Cell Supplier: SAIC Ningde Yikong Power System Co, prismatic cells. The NMC battery chemistry is considered to be one of the more contemporary chemistries in the EV space. However, "cutting edge" can be a moving target as battery tech is advancing so rapidly. It could be a great topic for a future video. What's driving your interest by the way, are you considering an MG4, or just curious about EV battery tech in general? 😊⚡
@siasek Thanks for your reply. I already have an MG4 (I picked it up in September). I am looking at the optimal charging regime that protects against battery degradation while fitting in with my driving needs. I wanted to understand at the physical level what is happening and learnt about how degradation affects the anode and cathode. On the cathode side of things there has been a development in high nickel chemistries called single crystal NMC that has much better charge cycle stability as well as energy density and power output. I know LG has started manufacturing such batteries but what about CATL?
Thanks , very interesting to me as the owner of one of these ev’s . The diagrams needed to be clearer if possible please and there seems to be some things I could not clearly understand in the pronunciation.
Hi, thanks for the comment. Unfortunately, diagrams or any similar data is nearly impossible to find. Fortunately MG put a few in their Chinese presentation, otherwise we would have nothing at all. 🙂
Hmm, I don't know. I researched it before making the video and came across the Q pronounciation more often, but perhaps you're right. Chinese is all Greek to me 😄
Way too much jargon which is not thoroughly explained. To really be a deep dive you should take the time to explain much more of the terminology which viewers may not be familiar with. I am assuming you have other videos where you look at the terminology in detail.
Interesting idea! I have thought about creating a series of videos that focus more on the basics of EV technology, so this would be right along those lines. Thank you!

are they easy to unmount and repair?
Hi, I think every battery in an EV is like that, it has be easy to service.
Do you know if the MG5 carries the same battery technology than the MG4? I don't mean the chemistry, I mean the battery architecture and burn protection@@siasek
Great video , do you think the one pack will last as long ( years) as BYD blade batteries, or how many cycles do you think it will last , cheers

Thank you! Finding all of that information in Chinese was a challenge 😄
Does anyone know the type of NMC battery used in the MG4. How cutting edge is the chemistry?

From MG I get the answer that is good to charge it on fast charger once a month.@@brendansheehan7714
Thank you I own an MG 4 and am keen to find out more about it
Thank you, hope you found the video useful. Which version MG4 do you have?
Sorry about the slow reply Exite 51
Thanks , very interesting to me as the owner of one of these ev’s . The diagrams needed to be clearer if possible please and there seems to be some

Hi, thanks for the comment. Unfortunately, diagrams or any similar data is nearly impossible to find. Fortunately MG put a few in their Chinese presentation, otherwise we would have nothing at all. 🙂
This for the NMC or LFP battery?
the NMC
51kWh battery is LiFePO.
thx :) interesting :)
Glad you enjoyed it! Thanks for watching 😊
👍
I think Qilin is pronounced as "Shi" lin
Hmm, I don't know. I researched it before making the video and came across the Q pronounciation more often, but perhaps you're right. Chinese is all Greek to me 😄
