With active thermal management, 10 years lifetime is possible provided the battery is cycled within a restricted 54% operating range. Together with battery capital cost and electricity cost, the life model can be used to optimize the overall life-cycle benefit of integrating battery energy storage on the grid.
Key factors impacting battery degradation rate are battery average temperature of 32oC, average SOC of 45%, maximum DOD of 74%, and daily Amp-hour throughput of 69 Ah (discharge direction, with positive current). Assuming repeated cycling in this mode for 365 days/year, the battery lasts 7.3 years to 70% of 75Ah name- Fig. 9.
Two methods to extend lifetime include (1) oversizing the battery and thereby restricting its maximum daily DOD and (2) adding battery thermal management. These tradeoffs are shown in Figure 9. Daily average SOC is maintained at 45% across all cases. The SOC operating range is narrowed at the maximum and minimum extremes to sweep DOD.
Abstract— Lithium-ion (Li-ion) batteries are being deployed on the electrical grid for a variety of purposes, such as to smooth fluctuations in solar renewable power generation. The lifetime of these batteries will vary depending on their thermal environment and how they are charged and discharged.
A battery life prognostic model was identified from 9 cell accelerated aging experiments conducted on 11 cells over 300 days at temperatures ranging from 0oC to 55oC and DODs ranging from storage to 100% DOD.
Due to their declining costs 2 and wide applicability, lithium-ion (Li-ion) batteries are one of the fastest-growing grid energy storage technologies. However, their investment costs are still relatively high and therefore adequate sizing and control strategies are required to maximize battery life and energy throughput.
