Batteries
The node defines the individual battery cells the battery pack. One battery cell model is defined per each disjoint domain group in the geometry selection.
Figure 3-3: Circuit diagram depicting the available elements of the individual battery models, defined for each disjoint domain group by the Batteries node (and child nodes). The circles on the left and right hand sides represent the positive and negative cell terminals, respectively. The directions of Icell and Iapp correspond to the situation during charging.
Two subnodes are also added by default — Cell Equilibrium Potential and Voltage Losses. Only one instance each of these subnodes can be present in the interface, so you cannot add additional instances of these subnodes, and they cannot be deleted. The selection of these subnodes are locked to the selection of the Batteries node.
Additional subnodes such as Thermal Event, Capacity Loss, and Short Circuit can be also be added. The Capacity Loss subnode is a singleton node and the selection is locked to the selection of the Batteries node. The Short Circuit subnode is also a singleton node with a default empty selection, that can be set to any of the domains of the Batteries node. The settings of the both these subnodes are similar to the nodes in The Lumped Battery Interface.
Battery Pack Settings
The Battery pack capacity (C) specifies the battery pack capacity.
The Initial pack cell state-of-charge (1) specifies the state-of-charge of the battery pack when the simulation starts.
