A simple calculation of LCOE takes the total life cycle cost of a system and divides it by the system''s total lifetime energy production for a cost per kWh. It factors in the system''s useful life, operating and maintenance costs, round-trip efficiency, and residual value. Integrating these factors into the cost equation can have a

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).

Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
Thus, the LCOE is $0.095 cents per kWh. This is lower than the national residential average electricity rate of $0.12/kWh. In addition, such a battery will deliver 34 MWh over its useful warranted life by the time it reaches its EOL of 80%, likely with many more years at a reduced capacity beyond the EOL 80%. Step two: Factor in ancillary costs.
While the coulombic efficiency of lithium-ion is normally better than 99 percent, the energy efficiency of the same battery has a lower number and relates to the charge and discharge C-rate. With a 20-hour charge rate of 0.05C, the energy efficiency is a high 99 percent. This drops to about 97 percent at 0.5C and decreases further at 1C.
Lithium-ion batteries have a fast discharge and charge time constant, which is the time to reach 90% of the battery''s rated power, of about 200ms, with a round-trip efficiency of up to 78% within 3500 cycles. It is well known that Li-ion batteries have become the most critical storage technology, especially in portable and mobile
