6 FAQs about [Energy storage power station battery discharge depth]

What is depth of discharge (DOD) in energy storage?

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.

What is a battery storage power station?

A battery storage power station, also known as an energy storage power station, is a facility that stores electrical energy in batteries for later use. It plays a vital role in the modern power grid ESS by providing a variety of services such as grid stability, peak shaving, load shifting and backup power.
