Does Ultra-Fast Charging Damage Batteries? The Li Auto L6 Response Reveals a Battery Management Battle

I noticed an interesting detail: when Li Auto responded to whether the new-gen L6 ultra-fast charging would damage the battery, they used the phrasing "within a normal vehicle usage cycle, you basically don't need to worry about degradation." There's nothing wrong with that statement per se, but as a PhD student who spends long hours in the lab staring at battery degradation curves and gets nagged by my advisor every day to "see if we can use reinforcement learning to optimize charging strategies," I feel like there are too many unspoken things behind those words.
