The last weeks were rich in information regarding electric mobility. It was the time to be quiet and observe. That’s why I didn’t write anything, I was absorbing every bit of information I could and reflect about it.
Now it’s time to share some of my thoughts 🙂
The last time Samsung SDI showed their cells they unintentionally revealed that BMW i3 was getting a battery upgrade.
Well, let me get Sherlock’s magnifying glass to analyze what we’re seeing in the photo above.
- The 60 Ah cell is past. The 94 Ah took over and replaced it as the biggest cell. When the stock of 60 Ah cells ends, BMW i3 get the new 94 Ah cells. That’s a 57 % increase.
- The 26 Ah, 28 Ah and 37 Ah cells correspond to cells for PHEVs (plugin hybrids). They have less energy density but are able to handle higher discharge/charge rates. The 94 Ah cells correspond to cells for BEVs (battery electric), these cells have higher energy density.
- The new and more energy dense cells that the pretty lady is holding are shorter than the 94 Ah cells, specially the one on the right. This enables the possibility of adopting a skateboard platform for batteries. These cells are reported to be 20-30 % more energy dense and I guess the same logic applies. The one on the left is for PHEVs and the one on the right is for BEVs.
We already know Chevrolet Bolt and Nissan Leaf 2 will have 60 kWh batteries, this means that the first generation electric cars with improved range will have their prices dropped sooner or later. This is great news for the massification of electric cars.
As soon as the 2015 Leaf is out of stock, we’ll see the Nissan Leaf have its price dropped. I’m following Nissan Leaf’s stock at cars.com and this is what we have at the moment:
- Modern Panasonic prismatic battery cells - 03/07/2020
- June was a record-breaking month for the Renault ZOE - 02/07/2020
- Hyundai launches its first electric minibus - 30/06/2020
