Guillaume Thenaisie,


This dataset has been used to implement a fast algorithm for the estimation of entropy-variations inside the battery. It represents electro-thermal measurements of a 1 Ah NMC811/graphite pouch cell obtained using the galvanostatic intermittent titration technique (GITT). Multiple experiments have been performed for different values of rest times in GITT with discharge current pulses of 1C amplitude and 2.5% SOC resolution at 20degC ambient temperature. The current-voltage data and the thermal data have been collected using a Neware BTS4000 5V6A battery tester and an in-house developed isoperibolic calorimeter, respectively.
