The example models a battery pack connected to an auxiliary power load from a chiller, a cooler, or other EV accessories. The Controls subsystem defines how much current the charger can feed into the battery pack based on the measurements of the cell state of charge, temperatures, and. .
The battery cell is modeled using the equivalent circuit method. The equivalent circuit parameters used for each cell can be found in the. .
To use this module to create a unique battery module, first specify the number of series and parallel-connected cells. Then specify the cell type. .
In this example, a battery pack is created by connecting three battery modules in series. A resistance models the cable connection between individual modules. A DC current source models the charger current and it is connected to the battery pack using a cable modeled as a resistance. A power load across the battery terminals models the. .
To enable fast charging, a cold battery pack is heated up to allow the passage of larger currents. The DC current profile subsystem estimates the DC current as a function of the minimum cell temperature in the battery pack. The coolant inlet temperature is constant at 288.15 K and defined by setting FlwT to a constant input value of 15. [pdf]
