Battery Aging Dataset for 15 Minute Fast Charging of Samsung 30T Cells
Borealis
Duque, Josimar; Phillip J. Kollmeyer; Naguib, Mina — 2023-09-25 This aging dataset was designed to be used for training/parameterization and testing of machine learning and conventional filter based state of charge and state of health estimation models. A number of characterization tests (HPPC, C/20 charge discharge, etc) are applied to each cell and are followed by repeating series of drive cycle discharges and a fifteen minute fast charge. The characterization and drive cycle tests are repeated until the battery cells reach 70% SOH (around 1500 to 2000 cycles). The rate of aging for each cell is different because each cell is fast charged using a different method (standard CC/CV, boost charge - higher current at low SOC, and two pulsed charge methods). The four cells tested are brand new 3Ah Samsung INR21700-30T lithium ion battery cells. The testing was performed in a thermal chamber at 25 degrees Celsius using an Arbin battery cycler.

Fast Charging and Characterization Dataset for Porsche Taycan LG E66 Battery Cell and Module
Borealis
Uwalaka, Lucia; Yao, Qi; Duque, Josimar; Phillip J. Kollmeyer — 2024-10-10 An LG E66 pouch cell and a battery module containing twelve E66 cells (6p2s) were tested. Both the cell and module were taken from a Porsche Taycan EV from a low mileage vehicle. Characterization tests, including numerous drive cycles, constant current discharge rates, and an OCV and HPPC test, were performed at -20, -10, 0, 10, 25, and 40degC. These tests are useful for creating battery terminal voltage models and for creating SOC estimation algorithms using machine learning and filter based techniques. The battery module was opened and instrumented with a battery management system to measure cell voltages and perform cell balancing. The module was also instrumented with numerous temperature sensors, including across the face of the cells so that temperature distribution throughout the module could be measured. The module was placed on a liquid cooling plate, like that in the vehicle, and tested for fast charging rates of 0.5, 1, 1.5, and 2C, as well as with the profile used in the Porsche Taycan vehicle.
