I am building a powertrain model in Simscape and the battery in SimPowerSystems is more suitable for my application. In order to interface with the rest of my Simscape model I am using interface blocks. However, when I use a voltage-current interface with voltage on the SimPowerSystems side and current on the Simscape side the simulation is running much faster than if I use a current on the SimPowerSystems side and voltage on the Simscape side. Could someone please shed some light on why this is happening?
Thanks in advance.
