Representative time-series dataset of battery operation under PV-module-integrated direct-coupling conditions

Zenodo (CERN European Organization for Nuclear Research)

Abstract

This dataset contains time-resolved battery operating parameters obtained from controlled laboratory emulation of direct PV-battery coupling under PV-module-representative operating conditions. The data were generated using the testing platform described in the associated manuscript, which combines software-controlled PV I–V emulation with controlled battery temperature profiles corresponding to PV-module operation. The dataset is provided as supplementary research data for the paper “A flexible battery testing framework for accelerated research on photovoltaic-battery modules and a representative test time series” published in Journal of Energy Storage Vol. 179 (2026) 124007 https://doi.org/10.1016/j.est.2026.124007. The dataset is intended as a simplified proxy for preliminary evaluation and comparative screening of battery chemistries on conventional battery cyclers. The dataset does not reproduce the real-time PV-battery voltage feedback and I–V operating-point formation captured by the full emulation platform. The time series represents the selected PV module, location, climate profile, load profile, and scaling conditions used in the study and should not be interpreted as a universal PV-battery operating profile.
