must be replaced. In the UPS system, the battery is in a floating state for a long time, so the aging of the battery is approximated by calendar aging, and its decay rate is slow and difficult to estimate accurately. The prediction methods for SOH can usually be divided into direct measurement methods, model-based methods and data-driven methods.

In particular, we notice that when a cell experiences calendar aging, its voltage decays over time along with its capacity/power.
