What is the competitive advantages of your DC motor controller?
I am sorry, but I believe there is a big misunderstanding. The swelling is NOT heat related! And it is independent of cell resistance. The swelling is SOC level related.
- 0 ~ 90 % SOC = not swollen, regardless of usage.
- ~100 % SOC = swollen, whether sitting on a shelf, charging, or discharging (at any current, and for any cell resistance)
Changing rate of LFP crystal lattice is 6-7% when charging.There will be some volumn change when SOC is 0~90%.
