Li-Ion Battery charge/discharge benchmark

Abstract

All tests in the battery laboratory to build the present dataset have been done using a setup that consists of a SBT 10050 battery test system from PEC in combination with an ICP 750 climate chamber from Memmert. The tested cell is a LiFePO4 (LFP) pouch battery from European Batteries. The average operating voltage is 3.2 V. The discharge and charge cut-off voltages are 2.5 V and 3.65 V respectively. The dimensions are height 275mm, length 166.5mm and width 13.3mm, and the weight of the cell is 1010 g. The tests were carried out at an ambient temperature of 23 degrees Celsius. Testing-machine adjustments were performed to improve the reliability and accuracy of the measurements. The first stage of the testing procedure was commissioning according to the USABC. After the capacity had stabilized in the conditioning stage, a full charge/discharge cycle was performed at a rate of C/25.
