Battery capacity refers to the amount of energy a battery can store and is typically measured in ampere-hours (Ah) or watt-hours (Wh). Energy storage capacity is the total amount of energy that can be discharged before the battery needs recharging, which is crucial for applications like renewable energy systems. A Battery Energy Storage System (BESS) allows for the collection and discharge of energy, helping to balance supply and demand in the grid23. [pdf]
