As the rapid development of new energy vehicle technologies and the need for better battery performance and reliable batteries management system (BMS), research on vehicle battery has become more and more important. Modeling and simulation of battery performance are commonly used in battery research. To model a battery accurately, obtaining battery characteristic parameters through real-time testing is critically needed.

This MS report studies the NCR18650B Lithium-ion battery performance with Real-Time BATTERY-IN-THE-LOOP testing. A custom battery test board is designed to hold the battery cell under the test and perform data acquisition. An equivalent circuit Lithium-ion battery model is developed using the battery parameters obtained from the real-time testing. The battery model is simulated and the simulation results are compared with the real-time testing results in the conclusion section.
