Create Battery Models and Design Battery Packs

Simulink® and Simscape Battery™ provide a design environment so you can model battery cells, design different battery pack architectures, and evaluate thermal and electrical responses of battery packs across normal and fault conditions. 

  • Parameterize cells based on manufacturer data sheets
  • Build customizable battery models with different effects, geometries, and topologies
  • Model cooling plates with customizable fluid paths and thermal connections to the battery pack
  • Explore cell-to-cell temperature variation and measure cooling efficiency
  • Set a suitable model resolution to strike a balance between model fidelity and simulation speed

“Assessing battery pack performance using hardware prototypes can be both slow and costly, so we rely on simulation to ensure that we minimize hardware testing. Modeling and simulation with MATLAB, Simulink, and Simscape is faster, safer, and less costly than building physical prototypes.”

Develop Battery Management System Algorithms

Use Simulink and Simscape™ to develop algorithms that ensure desired performance, safe operation, and acceptable lifespan under diverse operating and environmental conditions. With system-level simulation, verify functional aspects of the BMS design on behavioral models of battery, electrical circuitry, environmental conditions, and loads. Gain insight into the dynamic behavior of the battery pack and explore the effectiveness of BMS algorithms to:

  • Monitor cell voltage and temperature
  • Estimate state-of-charge (SOC) and state-of-health (SOH)
  • Control the battery charging profile
  • Balance the SOC of individual cells
  • Isolate the battery pack from source and load, when necessary

“MathWorks tools enabled us to develop key battery management technology using our own expertise, in an environment that facilitated early and continuous verification of our design.”

Test and Verify Battery Management System Algorithms

Generate C/C++ and HDL code from Simulink and Simscape models for rapid prototyping (RP) or hardware-in-the-loop (HIL) testing to validate the BMS algorithms using real-time simulation. Emulate the BMS controller so that you can validate algorithms before generating and implementing code on a microcontroller or FPGA. Test a BMS controller before using hardware prototypes by conducting HIL testing to simulate the balance of the battery system.

“Speedgoat together with MathWorks products offer us a very efficient workflow to design, test and validate algorithms for our battery management systems ...”

Generate and Deploy Code

Generate readable, compact, and efficient C/C++ and HDL code from battery system algorithms ready for implementation on production microcontrollers, FPGAs, and ASICs.

  • Use Embedded Coder® and the hardware support packages for embedded code generation and deployment on ARM® Cortex®-A/M/R, TI C2000, STM32, Infineon® AURIX™, Xilinx® Zynq®, and Intel® SoC devices
  • Use HDL Coder™ and the hardware support packages for HDL code generation and deployment on Intel (FPGA, SoC), Xilinx (FPGA, Zynq, RFSoC), and Microchip (FPGA, SoC) devices
  • Optimize code generation settings, improve code efficiency, and facilitate integration with legacy code, data types, and calibration parameters

“We generated AUTOSAR-compliant C code from our controller models using Embedded Coder and the Embedded Coder Support Package for AUTOSAR Standard.”
