Abstract
Excessive high temperature is an important factor for battery power and capacity degradation. Every charge-discharge activity escalates cell temperature, which results in higher degradation rates. Therefore, considering the impact of charge-discharge activities on battery temperature and consequently degradation rate is an indispensable step in establishing an optimal operation strategy for batteries. This paper describes a comprehensive investigation on the effect of battery charge-discharge on temperature and degradation. One year of operational data from a utility-scale solar photovoltaic (PV) plant with battery storage facility is used for this investigation. A strong correlation between battery temperature and discharge activities is identified, which can result in an excessive degradation of the battery.
