Data for: Bridging battery design and health assessment through virtual sensing and physics-informed learning

Additional fast-charging raw data for the paper "Bridging Battery Design Parameters and Health Assessment through Virtual Sensing and Physics-Informed Learning" (currently under review). If you make use of this dataset, please cite the paper. The raw dataset consists of 9 folders, including experimental data from different charging protocols: 0.6C0degCs1, 0.6C0degCs2, 0.6C35degCs1, 0.6C35degCs2, 1C25degC, 2C25degCs1, MC25degC, MC25degCs1, and one folder containing data generated by a digital twin model. 0_digital_twin_dataSOC and voltage curves were generated by sweeping four design parameters using our digital twin model: Particle radius of the negative electrode: CCCV generation #1.txtThickness of the negative electrode: CCCV generation #2.txtLithium-ion concentration in the positive electrode: CCCV generation #3.txtDiffusion coefficient in the negative electrode: CCCV generation #4.txt (1-8) experimental testSix kinds of loading profiles are included, such as fast CCCV charge, MCCCV charge, WLTC discharge, and combined CC+WLTC discharge. Each data file contains three main folders: 1. aging folder contains two subfolders:-- Cycling: Raw cycling data under different conditions. -- EFC: Data used to calculate the Equivalent Full Cycle (EFC) number. 2. mat contains processed data from the aging folder, includes: -- data.mat: Cycling data stored as a MATLAB data structure.-- EFC.mat: Pre-calculated Equivalent Full Cycle numbers.-- EOCV.mat: End.of-charge voltage for each charge cycle.3. RPT: Reference performance test conducted at 25 degC every 100 cycles for each condition, includes:-- CC charge and discharge tests for capacity assessment.-- HPPC (Hybrid Pulse Power Characterization) discharge tests for resistance measurement. WLTC in experimental testThe cells were first fully charged using different Crates. Then, WLTC profiles were applied to discharge the cells to different SOCs. This experiment was conducted at four temperatures: 0degC, 15degC, 25degC, and 35degC. WLTC+CC in experimental testIn this test procedure, the battery was first fully charged. Then, the WLTC profiles were used to discharge the battery to 90% SOC. After that, CC discharge was applied, mimicking as a V2G behavior.
