Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.
In this investigation, battery packs consisting of 49 single cells were simulated for three chemistries and three topologies. The number of single cells was chosen to be large enough to be representative of large battery packs, while small enough to limit calculation time.
The increments in pack capacity are also 138kWh. The small 5Ah cell allows a more granular approach to pack sizes, the downside is the number of cells that are used and hence the complexity of items such as the busbars. In simple terms the total energy in the pack is just the total nominal voltage x total nominal capacity.
Let us suppose we select a 50Ah cell with a nominal cell voltage of 3.6V A 400V pack would be arranged with 96 cells in series, 2 cells in parallel would create pack with a total energy of 34.6kWh Changing the number of cells in series by 1 gives a change in total energy of 3.6V x 2 x 50Ah = 360Wh.
The cost and performance of the battery systems are based on an assumption of approximately one cycle per day. Therefore, a 4-hour device has an expected capacity factor of 16.7% (4/24 = 0.167), and a 2-hour device has an expected capacity factor of 8.3% (2/24 = 0.083).
