High Voltage Battery Component

This is a road vehicle component to simulate the abstract dynamics of a high voltage battery pack.

This component provides several models of a high voltage battery, all of which are abstract and run fast.

🔵 Primitive model (BatteryHV_Primitive_refsub) is the simplest model and computes the voltage and current of the battery with no temperature dependence.

🔵 Basic model (BatteryHV_Basic_refsub) is built with Battery (System-Level) block from Simscape Driveline. This model has a simple equation-based terminal voltage model computed from the state of charge (SOC). This model does not compute the battery temperature.

🔵 BasicThermal model (BatteryHV_BasicThermal_refsub) is the same as the Basic model except that the battery temperature is computed.

🔵 SystemThermal model (BatteryHV_SystemThermal_refsub) is built with Battery block from Simscape Battery and Simscape Electrical. This model can simulate the terminal voltage more accurately (using more parameters) than the simple system model above. Optionally, this model can also simulate charging dynamics, fade, and aging.

🔵 SystemTable model (BatteryHV_SystemTable_refsub) is built with Battery (Table-Based) block from Simscape Battery and Simscape Electrical. This model takes tabulated data for open-circuit voltage and terminal resistance as a function of temperature and SOC. Battery temperature is computed. This model also needs the number of cells and their series-parallel circuit configuration information. Similar to the SystemThermal model, this model can optionally simulate charging dynamics, fade, and aging too.

Harness Model

Battery models are provided as referenced subsystems to componentize the models. They are used as a component of Battery Electric Vehicle model for vehicle system-level simulation, but they can also be used with a component test model (HarnessModel_BatteryHV) to run simulation focusing on the battery model.

The harness model is used in simulation case scripts in the SimulationCases folder in each model folder.
