Edit from 2018: In C++17 the answer to this question is different.You still have to store your arguments in a ::std::tuple, but when the time comes to call the function ::std::apply handles unpacking this tuple and calling the function for you. And if you need to use the indices trick for something other than what ::std::apply does, there''s ::std::integer_sequence and the

In this case, you can initialize the battery model only by clicking the Init button in the Battery Model dialog box to start the simulation.
Obtaining model parameters (other than the default values) can be dependant on your battery configuration and material properties. The default values are taken from Kim's paper 313. If you model a battery having a different design, you must provide a different set of battery parameters.
