Some studies on impact of temperature and DoD on performance of lithium-ion battery pack

It is known that the life of a Lithium-ion (Li-ion) battery is affected by charge/discharge rates, temperature, and depth of discharge (DoD). This paper investigates the effect of temperature and DoD on a 18650 Li-Ion cell. An experiment is set up to analyze the impact of temperature and DoD on the performance of Li-Ion cells. The test temperatures of 25°C and 35°C, whereas DoD of 80% and 90%, are considered for the analysis. The paper aims at studying the effects of these parameters on capacity degradation, discharge energy efficiency, and coulombic efficiency over the cell's lifetime.
