component batteryMultiDimModel % Battery Multi-D Model : 7 : rotates % This block models a battery module. It consists of multiple battery cells % that can be configured in series and parallel. Multiple copies of this % battery module can be connected in series and/or parallel to create a % full battery pack, such as is used for electric vehicles. The underlying % cell model is the Battery (Table-Based) block from the Simscape(TM) % Electrical library.
