Battery modeling refers to the creation of mathematical or computational representations of a battery’s behavior, performance, and internal states under various operating conditions. These models are essential tools for battery design, system control, state estimation, and lifetime prediction in applications such as electric vehicles (EVs), energy storage systems (ESS), and battery management systems (BMS).
Purpose of Battery Modeling:
Predict battery performance under different loads, temperatures, and aging conditions
Estimate internal states like State of Charge (SOC), State of Health (SOH), and temperature
Support real-time control in BMS and energy optimization systems
Enable battery digital twins for monitoring and forecasting
Assist in cell design and material selection before physical prototyping
