A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Depth of Discharge (DOD) A battery's lifetime is highly dependent on the DOD. The DOD indicates the percentage of the battery that has been discharged relative to the battery's overall capacity. Deep discharge reduces the battery's cycle life, as shown in Fig. 1. Also, overcharging can cause unstable conditions.
For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours. Cycle life/lifetime is the amount of time or cycles a battery storage system can provide regular charging and discharging before failure or significant degradation.
Optimizing Battery Energy Storage Systems (BESS) requires careful consideration of key performance indicators. Capacity, voltage, C-rate, DOD, SOC, SOH, energy density, power density, and cycle life collectively impact efficiency, reliability, and cost-effectiveness.
The lithium-ion battery has the characteristics of low internal resistance, as well as little voltage decrease or temperature increase in a high-current charge/discharge state. The battery is
Self-discharge, expressed as a percentage of charge lost over a certain period, reduces the amount of energy available for discharge and is an important parameter to consider in batteries
