Lithium-Ion Battery Parameter Estimation for HIL, SIL, and MIL Validation

With the rising focus on electric vehicles, lithium-ion batteries are widely used in the automotive market (EV, PEHV vehicles). The battery cells are arranged in a way that the battery packs are generated, and it becomes very important to protect the battery from over charge, deep discharge, and thermal runway.

The battery management system (BMS) is used to estimate the state of charge (SOC), state of health (SOH), and protect the battery packs from failure. To validate and perform a robust testing of BMS for a hardware-in-the-loop (HIL), model-in-the-loop (MIL), or software-in-the-loop (SIL) system, exact battery parameters are required.

In this presentation, you will learn on how the parameters of the batteries are identified for validating the BMS using experimental data from a test bench and mathematical model of the battery packs.
