Title
State of health determination of batteries at various operating conditions
Description
Objective of the study is to get a clear idea on the cyclic performance of duty operation of Batteries. Batteries are an integral part of solar plants and wind energy farms due to the fact that energy storage is vital in these places. Various types of losses related to the performance are clearly analyzed and studied. Assessment of State Of Health and State Of Charge is critical in order to maximize the performance and lifetime of a battery. Batteries were subjected to temperature and charge/discharge rate variations and found that the state of health degradation was severe at high temperature along with faster rate of charging compared to other evaluation conditions. The entire research was conducted at the Alternative Energy Technology Laboratory located at Arizona State University, Mesa. It involved the use of various instruments namely the Programmable Voltage Regulator for charging, Computerized Battery Analyzer and Programmable Electric Load for discharging and also the PARSTAT potentiostat for measuring the impedance of various battery technologies under study. At first, the Batteries were discharged and based on the time taken, it was charged for the next cycle. Impedance measurement was done at regular cycle intervals in order to study the degradation of health. For every cycle, the battery capacity was also calculated and noted down. . The results obtained show that low and stable impedance over the given cycle life is an important consideration in the selection of batteries according to the applications.
