To avoid things getting very complex very quickly it might be easier to take a very simplistic apporach and model the batteries chief characteristics such as terminal voltage, and ampere/hour capacity. Since there is no such thing as a perfect power source you could go to much more detail - modelling the internal resistance of the battery and it's own capacitive and inductive load characteristics for example. But for the beginning surely we just need to know how what voltage it will supply and how much current capacity is available don't we?
I think this would make it easier for situations like alternator offline or (as happened almost every flight in a C206 I know of!) the fan belt coming off mid-flight. I'm sure in these situations one would want to turn off everything but the essential items like the radio etc. - as I'm not a pilot (yet!) I don't know. Furthermore, if we need more accurate battery discharge modelling to represent the inherent voltage drop when the load approaches or exceeds the maximum the battery can supply in it's current condition we can have generic functions in code to model the behaviour and supply the values for the specific case from XML. Just my 2p worth :-) What do people think?
