What is SoH (State of Health)?
SoH stands for State of Health, therefore meaning how healthy an energy storage cell, or a module, or a whole rack are.
SOH (State of Health) compares current capacity to the original, revealing battery aging status. Cycle life is the total number of full charge–discharge cycles a battery can complete before dropping below 80% capacity. These metrics are vital for battery selection and performance planning in energy storage systems.
SOC (State of Charge) shows the percentage of energy remaining in a battery. SOH (State of Health) compares current capacity to the original, revealing battery aging status. Cycle life is the total number of full charge–discharge cycles a battery can complete before dropping below 80% capacity.
It describes the storage capacity of the battery in the current state, that is, the ratio of the available capacity of the battery in the current state to the available capacity of the battery in the outgoing state, and the unit is the percentage (%). Theoretically, the SOH of the battery is 100% when it leaves the factory.
The State of Health (SoH) is a crucial metric used to evaluate the overall condition and performance of a Battery Energy Storage System (BESS).
