A Review on Testing of Electrochemical Cells for Aging Models in BESS

Abstract

The use of electrochemical cells is becoming more widespread, especially in the energy industry and battery energy storage systems (BESSs). As we continue to deploy BESSs, it becomes increasingly important for us to understand how these systems age and accurately predict their performance over time. This knowledge is essential for ensuring that the systems operate optimally and can be properly maintained. Since the structure of a BESS is different from a single electrochemical cell, the existing models at the cell level cannot predict and estimate the life of the BESS with suitable accuracy. Furthermore, the test protocols available at the cell level mostly cannot be executed at the BESS level for many reasons. Therefore, in this paper, a review of test protocols for building aging models for BESSs has been performed. After reviewing the protocols for a single electrochemical cell and addressing the differences between BESSs and cells, a review of the works performed on a larger scale has been carried out, and the possible ways for testing the BESS for aging models were investigated.

An Evaluation of Battery Degradation and Predictive Methods Under Resistive Load Caused by Intermittent Solar Radiation

“…Millner. A explained the detailed aging at 15˚C and 35˚C four kinds of different chargedischarge methods [16][17][18] [20].…”

“…Energy storage capacity optimization and dispatch strategy are auxiliary tools of this model [26]. The weighted Ah method shows the effect of DoD on battery life in equation (17).…”

“…The study has revealed that the multi objective parameter study on a large-scale system is the need of the hour. The ageing and performance degradation of the system over time must be taken into account when studying large-scale BESS systems [17]. The challenges in aging prognostics have been discussed by Liu et al [18].…”
