3 Battery model using Simscape toolbox

How do you accurately predict a battery pack's behavior under real-world EV driving conditions? In this hands-on tutorial, we build a high-fidelity Battery Model using the Simscape Toolbox to monitor and plot State of Charge (SoC), current, voltage, and temperature in real-time!

Instead of relying on simple algebraic approximations, we leverage Simscape Electrical to build an Equivalent Circuit Model (ECM). We will explore how to model the battery's internal resistance and open-circuit voltage dynamics, connect thermal ports to capture temperature spikes during high current draw, and extract critical performance plots to evaluate cell degradation and thermal health.

What You’ll Learn in This Video:

Equivalent Circuit Modeling (ECM): Translating cell dynamics (OCV, internal resistance, and RC pairs) into a physical Simscape network.

Electro-Thermal Coupling: Connecting electrical behavior to thermal masses to simulate how temperature changes with varying current demands.

Tracking State of Charge (SoC): Setting up Coulomb counting and lookup tables inside the cell parameters to dynamically monitor SoC.

Analyzing Scope Outputs: Step-by-step interpretation of the multi-plot scopes tracking transient voltage response, current spikes, and thermal runaway risks.

Are you using simple lookup-table battery models, or are you developing multi-RC branch circuits to capture transient behaviors? What is your preferred cooling method to keep your simulated cell temperatures within the ideal window? Share your simulation strategies below!
