Battery Tech in the Mini Cooper SE

[Sean_MacGuire]

been diving into the world of EV batteries, and it’s fascinating how different automakers use technologies like NCM (Nickel-Cobalt-Manganese), NCA (Nickel-Cobalt-Aluminum), or LFP (Lithium Iron Phosphate). Does anyone know what BMW decided to go with for the Mini Cooper SE? What do they have now?

I’ve read that some brands are leaning toward LFP for better longevity and thermal stability, while others stick to NCM or NCA for higher energy density. Curious where the Cooper SE lands and why BMW made that choice. Would love to hear from anyone who has insights into the tech behind the Mini's high-voltage battery!

Hmmm... What I know is twelve packs of lithium-ion cells are used in the battery, which is positioned in a T-shape beneath the back seats and between the front seats. I'm curious why this an interesting topic for you?

From what I know, the Mini SE uses a smaller battery than the i3. The bigger i3 battery wouldn't fit in the Mini.

It's not a repurposed i3 battery, but a 97.2Ah NCM type with prismatic CATL cells, as the i3 cells wouldn’t fit the available space.
