Issue406 new battery model
This Pull Request refers to the issue #406
It contains a model for a rack of batteries and a room, where these batteries can be installed. The model calculates the thermal performance of a room which contains different battery racks. The model needs an input which contains e.g. a vector of the battery loss.
It is possible that the names for the parameters and variables do not exactly correspond to the Modelica Guidelines, because I was not sure about the correct naming of some parameters. I hope that you can help me to fix this problem.
The solution with the temperature of the second battery is also not perfect for the moment. If you have any ideas to improve that, please let me know :)
