BATTERY_COMPONENT_MODEL

Specifies a battery component model and its parameters.

Type

AcuSolve Command

Syntax

BATTERY_COMPONENT("name") {parameters...}

Parameters

component_type (enumerated) [=none]

Type of component in the battery module.

none: No label given to an electrical component. This represents all electric components that are not cells, tab/terminals, or busbars.
battery_cell: A battery cell representing the homogenized region of the battery, for example, electrode pairs and separator.
tab_positive: Positive terminal/tab of a battery cell.
tab_negative: Negative terminal/tab of a battery cell.
busbar: Busbar component in the module.

cell_id (int) [=1]

Cell ID of battery cell in a module.

initial_state_of_charge (real) [=1.0]

The initial state of charge in a cell in a battery module. This parameter can only be variable across different cells when the module current is provided as an input.

battery_module (string) [=no default]

User-given name of the BATTERY_MODULE to which this component belongs.
