| Abstract Scope |
This work focuses on the use of modified 18650 Li-ion cells to include internal thermal sensors for monitoring the internal temperatures of individual batteries during pack cycling. A four-cell battery pack was used, with two series of two LiCoO2 cells each. The cells were cycled at a current of 1.3 A (C-rate of 0.5) and through a voltage range of 6.0 – 8.4 V based on the recommendations of the manufacturer. During cycling, the internal and external temperatures of the cells were monitored, as well as the voltages of the individual cells and the overall voltage and current of the battery pack. The results of the experiment show the variations of internal and external temperatures and voltages of the individual cells, as well as their variation over cycling, and how this information can be used for state of health determination in both individual cells and battery packs. |
