This paper presents a unique cheaper battery safety test bench for electrical and mechanical performance evaluation of lithium-ion batteries where mechanical performance is tested using software and electrical characteristic is tested using hardware. In this work, simulation of mechanical performance of lithium-ion battery such as thermal modelling test at various temperature has been carried out using Comsol software, where battery voltage and temperature are monitored as a control input during a drive cycle and state of charge of the battery on the positive (65-80%) and a negative electrode (14-29%) is monitored and triggered as a control output. A hardware test bench has been developed to execute various electrical tests for evaluating battery performance during a discharge cycle. These electrical tests have been carried out on the LabVIEW software to obtain real-time data and display the battery related information such as voltage and current curves. Further, a battery safety test like external short circuit test has been performed and also for improving the battery efficiency capacitors are connected parallelly with varied load condition. Overall, in this exploration, a newly evolved, accurate, affordable battery testing and monitoring system has been developed.
