in the PV industry. Batteries experience a wide range of operational conditions in PV applications, including varying rates,of charge and discharge, frequency and depth of discharges, temperature fluctuations, and the methods and limi.
The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery. For example, if the DOD of a battery is given by the manufacturer as 25%, then only 25% of the battery capacity can be used by the load.
Battery design life: Factoring in DoD to real-life usage scenarios. In essence what all this means is that DoD should be a key consideration in the design of any battery storage system. A battery bank''s ''design life'' is the number of years which it should operate within the parameters which it is engineered to function.
