Enhanced Electrical and Mechanical Characteristics Monitored by Various Software for Lithium-Ion Battery Tests

Abstract

This paper represents a battery test bench for testing of lithium-ion coin cell (LiMn2O4) batteries for electrical and mechanical characterization where mechanical tests are performed using Multiphysics software and electrical characteristics are tested using hardware circuits. A hardware test bench has been developed to analyze various electrical tests for evaluating coin cell battery performance during a discharge cycle. These electrical tests have been performed on the data acquisition software to obtain real-time data and display the battery-related information such as voltage and load curves. Further, a battery test like an external short circuit test has been performed and also for improving battery characterization, the capacitor bank has been connected parallelly with the battery bank. Also, simulation has been performed for mechanical characterization of lithium-ion (LiMn2O4) coin cell battery such as thermal modeling test at various temperature ranges (26–124 °C) that has been simulated using Multiphysics software, where cell temperature has been analyzed on the various range. Also, various tests during simulation have been performed and analyzed during a drive cycle. The state of charge has been triggered for both negative and positive electrodes.
