As the integration of renewable energy sources into the grid intensifies, the efficiency of Battery Energy Storage Systems (BESSs), particularly the energy efficiency of the ubiquitous lithium-ion batteries they employ, is becoming a pivotal factor for energy storage management.
This is the ratio between electric energy out during discharging to the electric energy in during charging. The battery efficiency can change on the charging and discharging rates because of the dependency of losses on the current.
The main technical measures of a Battery Energy Storage System (BESS) include energy capacity, power rating, round-trip efficiency, and many more. Read more...
This also contributes to battery strain by reducing cycle life. Battery efficiency is gaining interest. This is especially critical with large battery systems in electric vehicles, energy storage systems (ESS) and satellites. The efficiency factor is commonly measured by coulombic efficiency.
For example, if a lithium-ion battery has an energy efficiency of 96 % it can provide 960 watt-hours of electricity for every kilowatt-hour of electricity absorbed. This is also referred to as round-trip efficiency. Whether a BESS achieves its optimum efficiency depends, among others, on the Battery Management System (BMS).
Age also plays a role. Voltaic efficiency is another way to measure battery efficiency, which represents the ratio of the average discharge voltage to the average charge voltage. Losses occur because the charging voltage is always higher than the rated voltage to activate the chemical reaction within the battery.
