The higher the DOD, the more energy has been extracted from the battery in that cycle. DOD is a critical factor because it is a function of the overall lifespan and health of the battery. Batteries with deeper discharge cycles tend to experience more wear and tear and may have a shorter cycle life.
Depth of Discharge (DOD) is another essential parameter in energy storage. It represents the percentage of a battery’s total capacity that has been used in a given cycle. For instance, if you discharge a battery from 80% SOC to 70%, the DOD for that cycle is 10%. The higher the DOD, the more energy has been extracted from the battery in that cycle.
Ramadass et al. believed that the decrease of battery SOC during the cycle indicated the loss of lithium ions, the increase of SEI film resistance caused the decrease of battery discharge voltage, and the decrease of electrode diffusion coefficient caused the attenuation of discharge capacity of battery.
It was found that after the battery was cycled at different ambient temperatures, the electrode would expand and crack, resulting in a decrease in battery capacity. It was found that the battery with new diaphragm had higher cycle performance after cyclic charging and discharging under the same working condition.
Battery cycle life estimation SOH, as a quantitative performance index, indicates the ability of a lithium-ion battery to store power. There is no unified standard for health status. There are coupling and overlapping steps between the SOC, SOH, and RUL, and separate estimation does not guarantee accuracy but increases computational effort.
Capacity and power degradation depend on battery degradation modes. External factors that affect batteries, such as battery ambient temperature and battery charging and discharging ratio, threaten the life of batteries.
