Batteries
Explore examples that illustrate modeling and simulation of various types of batteries.
Featured Examples
Lead-Acid Battery
Model a lead-acid battery cell using the Simscape™ language to implement the nonlinear equations of the equivalent circuit components. In this way, as opposed to modeling entirely in Simulink®, the connection between model components and the defining physical equations is more easily understood. For the defining equations and their validation, see Jackey, R. "A Simple, Effective Lead-Acid Battery Modeling Process for Electrical System Component Selection", SAE World Congress & Exhibition, April 2007, ref. 2007-01-0778.
Lead-Acid Battery with Dashboard Blocks
Model a lead-acid battery cell using the Simscape™ language.
Lithium-Ion Battery Pack with Fault
Simulate a battery pack consisting of multiple series-connected cells in an efficient manner. It also shows how a fault can be introduced into one of the cells to see the impact on battery performance and cell temperatures. For efficiency, identical series-connected cells are not just simply modeled by connecting cell models in series. Instead a single cell is used, and the terminal voltage scaled up by the number of cells. The fault is represented by changing the parameters for the Cell 10 Fault subsystem, reducing both capacity and open-circuit voltage, and increasing the resistance values.
Lithium-Ion Battery Pack with Fault Using Arrays
Simulate a battery pack that consists of multiple series-connected cells. It also shows how you can introduce a fault into one of the cells to see the impact on battery performance and cell temperatures. The battery pack is modeled in Simscape™ language by connecting cell models in series using arrays. You can represent the fault by defining different parameters for the faulty cell.
Lithium Battery Cell - One RC-Branch Equivalent Circuit
Model a lithium cell using the Simscape™ language to implement the elements of an equivalent circuit model with one RC branch. For the defining equations and their validation, see T. Huria, M. Ceraolo, J. Gazzarri, R. Jackey. "High Fidelity Electrical Model with Thermal Dependence for Characterization and Simulation of High Power Lithium Battery Cells," IEEE International Electric Vehicle Conference, March 2012.
Lithium Battery Cell - Two RC-Branch Equivalent Circuit
Model a lithium cell using the Simscape™ language to implement the elements of an equivalent circuit model with two RC branches. For the defining equations and their validation, see T. Huria, M. Ceraolo, J. Gazzarri, R. Jackey. "High Fidelity Electrical Model with Thermal Dependence for Characterization and Simulation of High Power Lithium Battery Cells," IEEE International Electric Vehicle Conference, March 2012.
Lithium Pack Thermal Runaway
Model a thermal runaway in a lithium-ion battery pack. The model measures the cell heat generation, the cell-to-cell heat cascade, and the subsequent temperature rise in the cells, based on the design. The cell thermal runaway abuse heat is calculated using calorimeter data. Simulation is run to evaluate the number of cells that go into runaway mode, when just one cell is abused. To delay or cancel the cell-to-cell thermal cascading, this example models a thermal barrier between the cells.
