Data for Design optimisation of supercapacitor-based energy storage systems for high peak power applications Ahmed Fares (25046611) Mahyar J.

Cell modelling and experimental testing were used to evaluate candidate cells under realistic application-specific cycling conditions. Results revealed significant deviations from rated specifications when subject to the harsh conditions of the target aerospace application, particularly under low temperatures. A multi-objective optimisation, incorporating energy density, thermal stability, and ESS system weight, initially identified one low-rated cell as the most promising option. However, subsequent cycle-ageing tests showed that this cell type did not sustain capacity over the required lifetime, whereas two other electric double-layer capacitor models were able to meet the 100,000-cycle threshold with variability between units. These findings highlight the importance of integrating long-term ageing performance alongside temperature stability and energy density when selecting supercapacitor technologies for high peak power ESS design. 2026-04-28T00:00:00Z Dataset Dataset 10.82444/warw.33908902.v1 https://figshare.com/articles/dataset/Data_for_Design_optimisation_of_supercapacitor-based_energy_storage_systems_for_high_peak_power_applications/33908902 CC BY 4.0
