Battery Pack Cell Balancing
Implement a passive cell balancing for a Lithium-ion battery pack. Cell-to-cell differences in the module create imbalance in cell state of charge and hence voltages. In this example, the balancing algorithm starts when the battery pack is idle and the difference in the cell state of charge is above a certain predefined value.
Battery Pack Thermal Management
Model an automotive battery pack for thermal management tasks. The battery pack consists of several battery modules, which are combinations of cells in series and parallel. Each battery cell is modeled using the Battery (Table-Based) Simscape™ Electrical™ block. In this example, the initial temperature and the state of charge are the same for all cells. Four battery modules, three similar and one differing from the other three, are connected in series to simulate a battery pack. The results in this example assume an initial ambient temperature equal to 25 degree Celsius. The Coolant Controls subsystem defines the logic used to determine the battery pack coolant flow rate.
Battery Pack DC Fast Charging
Model an automotive battery pack for DC fast charging tasks. The battery pack consists of several battery modules, which are combinations of cells in series and parallel. Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. The cell capacity varies according to the manufacturing tolerances or uncertainties. Three battery modules, two similar and one differing from the other two, are connected in series to simulate a battery pack. The results in this example assume an initial ambient temperature equal to zero degree Celsius. The Controls subsystem defines the logic to determine the battery pack charging time and current.
Battery Pack Short Circuit
Model a short-circuit in a lithium-ion battery module. The battery module consists of 30 cells with a string of three parallel cells connected in a series of ten strings. Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. There is no coolant flow modeled in this example. The battery module is shorted with a 0.1mOhm resistor. There is an inrush current followed by cell quick discharge and heating up. Once the cell reaches the trigger temperature for thermal runaway and cell venting, the electrical circuit is disconnected to stop the electrical simulation.

Ultracapacitor with Converter
Use a DC-DC converter to maintain a constant load voltage when drawing power from an ultracapacitor. The converter supplies power to the load and the capacitor voltage drops. The protection circuit disconnects the load when the capacitor voltage drops below a threshold value of 4V. At 10 seconds, the generator turns on, supplies power to the load and charges back the capacitor.

Battery Pack Fault Protection
Model fault and fault protection using a fuse in an automotive battery pack. The battery pack consists of several battery modules, which are combinations of cells in series and parallel. Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. Four battery modules, three similar and one differing from the other three, are connected in series to simulate a battery pack. The results in this example assume an initial ambient temperature equal to 25 degree Celsius. The Control subsystem defines the logic used to determine the battery pack coolant flow rate. A fuse is placed inline to battery pack as a measure of fault protection.
Peak Shaving with Battery Energy Storage System
Model a battery energy storage system (BESS) controller and a battery management system (BMS) with all the necessary functions for the peak shaving. The peak shaving and BESS operation follow the IEEE Std 1547-2018 and IEEE 2030.2.1-2019 standards.
