🔋 DOD + C-Rate = Battery Stress
Why do two BESS projects using the same LiFePO4 cells sometimes show very different degradation?
Because cycle life is not just about the number of cycles.
Depth of Discharge (DOD) determines how deeply the cells are cycled.
C-rate determines how quickly energy moves in and out.
When both become…Read More
🔋 Calendar Aging vs. Cycle Aging: What Really Degrades a BESS?
A battery does not degrade only because you charge and discharge it.
Even when a BESS is sitting idle, its cells continue to age. This is calendar aging.
At the same time, repeated charge-discharge operation causes cycle aging.
The challenge for BESS engineers is…Read More
