Empirical Degradation-Aware Sizing of Hybrid Photovoltaic--Battery--Supercapacitor Energy Storage Systems for Electric Vehicle Charging Stations: Cycle-Life Calibration, Real-World Demand Validation, and Geographic Tariff Analysis

This dataset contains all numerical results, statistical validation data, sensitivity analysis outputs, and publication figures supporting the paper under review (August 2026). The repository includes: (i) best-found sizing results for four case studies and four algorithms (GWO, BBO, AO, ARO) under a rule-based energy management strategy; (ii) 30-run statistical validation with Friedman rank test (chi2=79.24, p<0.0001), Nemenyi post-hoc analysis, and Wilcoxon signed-rank tests -- GWO CV=0.053%, near-deterministic; (iii) sensitivity analysis for alpha_comm and kp; (iv) real geographic tariff validation using SCE TOU-EV-9 (Los Angeles), Vattenfall Zakelijk + ACM ODA (Amsterdam), and ANEEL/CPFL B3 (Sao Paulo) -- revealing that SC bank size is driven by local demand charge level, not by energy price or solar resource; (v) all publication figures. SC integration reduces BESS equivalent full-cycle count by 21.1% (247 to 195 cycles/yr), extending effective BESS service life by 2.2 years.
