Dataset contains charging and discharging (Voltage & Current vs. Time) graphs of various battery chemistries. One set of graphs is from a 23 Ah Lithium Titanate Oxide (LTO) battery module. Constant current and pulsed current was used in the tests. Indvidual cell voltages were measured along with whole module current and temperatures of certain elements in the module. Tests were done to evaluate the performance of the module at different current levels and to create a test setup that can be used in the future for other modules. Other sets of graphs are from 18650 form factor Lithium-ion batteries of 3 different chemistries. Cell voltage, current and surface temperature were recorded during the tests. Test was automated by a lua-script, that configured the correct setting and triggered the measurements. Fast data sampling rates and high-precision measurement equipment was used to try to capture the small details and differences present in the different chemistries. These small details stored in this dataset can help in developing battery cell simulation models that more accurately represent the different properties of these chemistries.
