InsideEVs Podcast episodes

The anode free, batteries show a lithium layer accumulating and disappearing as it is charged and discharged. The problem is mechanical stress in the cell. Perhaps not as bad as a silicon anode, still you don't like to see the internal structures of a battery change volume as that leads to stress than can destroy the battery internals.

Personally I would have more confidence if their initial, target customers were cell phone, pad, and laptop batteries. Prove it works there and automotive makes sense. But starting out with automotive is the wrong order.

Good point, Bob. They mentioned that they accounted for this expansion and that it was unidirectional (as opposed to expansion of silicone in electrodes being omnidirectional), but as you say, mechanical stress does raise eyebrows, if not legitimate concerns.
 
I found a more technical discussion about the Samsung paper on a 900 kW/l Solid State Battery:

A little old, June 11, 2020, it is enlightening without going too deep in the weeds.

Another article about Toyota's solid state battery. Looks like it will leap frog them ahead of everyone else, incl Tesla.

Yes, this Toyota cell sounds pretty good so far, especially the charge speed. I don't get excited by claims of double the energy of batteries now, because they don't say which batteries. Double the energy density of a BYD blade battery would be less impressive than double the energy density of a Tesla cell. Give me gravimetric density or give me...um...pizza.
 
Episode #39. I find it ironic that Kyle is the host of your most popular YouTube episode where he enthusiastically goes over the the fine details of the Ariya and in this podcast he couldn't be much more negative. It's like Dr Jekyll and Mr Hyde. Then Tom has a go at people who are enthusiastic about Chademo. So, it seems that it is only sensible people who are enthusiastic about CCS. I really don't care. Explain what actually makes one better than the other. What are the pluses and minuses of Nissan going from Chademo to CCS which doesn't lean on "everyone else is using CCS." If I get an Ariya, what benefit am I going to see from having used Chademo with my Leaf these past 5 years. I'm much more interested in technical information than emotional drum beating and people prejudices. I didn't care if others didn't like the looks of the first Leaf. I loved it! And I don't care if Kyle and Tom don't like the looks of the Ariya. I think it's intriguing. It's just opinions which are of no use to whether to buy the car, or not.

What I want to know is has Nissan finally done it right? Does the Ariya TMS really make a difference? How far will the Ariya actually go on a charge, i.e. will I be able to drive across Canada without a problem? Are the interior bits and pieces up to the reliability that I've come to expect from the Leafs I have owned?

This is an example of why I have given up watching these podcasts. Instead of getting good technical information it's whatever way the wind is blowing opinions which are of little use.

Ariya NMC battery pack will be supplied by CATL a step up from the AESC packs used on the Leafs. I am sure a trip across Canada will not be an issue as CATL has proven to be durable, and is currently second to LG the largest supplier for several manufactures.

In his first walk around video, Kyle presents the car and gives us the facts without a lot of critical opinion. In a couple podcast episodes since, Kyle has given his personal opinion about various aspects of the car. They are not, as you mention, especially positive.

Regarding Chademo, the problem is that its becoming an orphaned technology. Higher power versions were far too slow to be implemented and now it's facing obsolescence. I don't think people feel especially emotional one way or the other when it comes to charging equipment standards. I think most, though, recognize the advantages to having as few "standards" as possible. Personally, I had hoped the auto world would adopt the Tesla standard, as the handles are much smaller and easier to manage, but it looks like we're stuck with CCS.

This show was recorded live and it looks like we're going to continue doing it that way. Join us on Friday mornings at 9:30 EST if you'd like to watch live and ask questions.

I really enjoy watching informed EV enthusiasts speak positive on new products and the technology's that go with it. One of the best podcasts I have viewed so far.
Delighted to see Hyundai hit the jackpot with the Vehicle to Load technology, and will be very useful as a back-up 3.5 kW generator for many applications such as construction, camping, topping up another electric vehicle in need, power outages, 12 V battery charger- ( just being facetious:D) to name a few, making full use of the battery pack, a BEV industry first.

InsideEVs has started a weekly podcast series titled (we think, appropriately) the InsideEVs Podcast. We do a video format and host the episodes on the InsideEVs YouTube channel (which is also pretty new), but you can find it on the usual podcast platforms like Spotify, Tune In, Google and Apple Podcasts, etc. We have a panel discussing the top news stories from the week and we publish every Saturday morning at 9:00 AM Eastern.

I'll post each episode in this thread as they publish. Feel free, of course, to discuss any episode here as well. :)

Episode one:

Hi Domenick, I posted this on the insideevs youtube channel as well but wanted to add it here out of the yt clutter. You guys should talk about the commoditization of vehicle components, and how the market may start to look like the PC clone makers of 80's. Especially with EV's. For us older guys it looks like the same thing could happen in the automotive world and the operating systems will be the differentiator once again. Of course they will be more like hybrid operating/control systems that may still require some collaboration.

BTW and off topic - I graduated from FSU and grew up in Pensacola. I sure miss the south!

Hey there! So, I'll share your thoughts with my co-hosts, but I'm not sure there will be a similar level of commoditization with EV components. At least, not for some time. There are some companies making components -- in my mind, I'm thinking motors and controllers are the main ones -- but I don't see many large manufacturers using them. I would note that Ford are using integrated drive modules from BorgWarner in the Mach-E, but the OEMs with the big EV programs like GM and VW are looking at vertical integration and scale as a way of keeping costs down and their EVs competitively priced.

With longer range being such an important factor and improved efficiency being the lowest-cost way to achieve it, OEMs are still looking at any advantage they can gain. In the EV-startup world, that's especially true. Tesla designs its motors, as does Lucid. Even Zero Motorcycles designed their own motors (in their case, they do use a 3rd party's controller).

Even batteries only have a moderate level of commoditization. Yes, the cells can be relatively standardized, but there are a lot of different ways to package them, and so until cell performance becomes much better, this lack of uniformity in pack design between OEMs may continue. I do see a day when energy storage could be a commodity, but I think it's still a long way off. Maybe in the 2040-2050 range.

Domenick - I totally agree with you on the more established automakers, I was thinking more along the lines of companies like Aptera, Apple, Sony and other entrants that don't have the manufacturing capabilities of the big guys. I was just thinking smaller companies, and bigs ones with no automotive manufacturing experience, may be able to piece together all the components without manufacturing any of them. I also agree that the big guys will try to prevent this from happening in any way possible, making most parts themselves. Thanks for responding to my thoughts with great detail, it's very much appreciated.
