Samsung SDI has a good habit of showing us the future instead of speaking about it.
I remember when I first saw a photo of 60 Ah and 94 Ah cells at Frankfurt Motor Show in 2015 and I speculated in the comment section of insideevs.com that it could mean a range increase for the BMW i3, this was 8 months ago and I was right.
Frankfurt Motor Show is now in the past, what Samsung SDI showed us this time at Beijing Motor Show?
A lot of good things for electric cars.
This is what Samsung SDI has to say:
“Samsung SDI exhibited various types of cells and modules including 37Ah, 50Ah, 94Ah, 120Ah, and more. 50Ah cell has improved capacity by 35% compared to 37Ah cell, and 120Ah by 28% compared to 94Ah. In particular, 37Ah and 50Ah cells, and 94Ah and 120Ah cells are applied the same standard type modules, respectively. Standardizing module type makes it easy to standardizing car design, so it’s an advantageous feature.”“Usually a module consists of 12 battery cells tied together in a row, so applying 50Ah and 120Ah cells to the existing module design allows development of electric cars with extended driving distance, greatly saving development cost. In this respect, it attracts high attention of many car makers.”
This is my comment:
- The 60 Ah cell has no longer the same volume of the 94 Ah, is now smaller. Previously I thought that the 60 Ah cell was going to be discontinued because of the 94 Ah introduction.
- 94 Ah and 120 Ah cells have the same volume and can replace each other. This I already knew when I said in previous articles that the BMW i3 will get the 94 Ah then a year later the 120 Ah cells. This will give the i3 a 150-160 EPA miles range and 43,2 kWh battery.
- The 50 Ah cell is very small, it looks like a smartphone in the lady’s hand. It’s perfect for the skateboard design, like Tesla Motors uses. It will also be perfect for small batteries in electric motorcycles, bicycles or even tandem cars like Opel Rak-e and Volkswagen Nils (I don’t miss an opportunity to talk about those two).
- Not only BMW’s all electric cars will get battery upgrades soon, but plug-in hybrids will also get them. For example, currently the BMW X5 xDrive40e uses 26 Ah cells.
- I like the Samsung SDI strategy better than LG Chem. They give me more information to write about :). LG Chem is surprisingly quiet these times. The last time I talked to them they were very disappointed with their automakers partners, because they had new improved cells ready for them, but they didn’t seem interested. I’m looking at you Renault, make the Zoe 44 kWh and Twingo ZE already!!! Stop the bullsh*t about saying that no one wants electric cars. Tesla Model 3 and 400.000 paid reservations proved you wrong!!! By the way, let Zoe’s drivers buy the battery, it isn’t so expensive like you want them to think.
Regarding traditional automakers I think that BMW is the one most interested in creating good electric cars and Samsung SDI will benefit from that partnership. I have hopes that LG Chem will find a better partner in Hyundai and Chevrolet than Renault is proving to be.
What you you think? Did I missed something? Comment below.
