I am getting a new wheel chair and in preparation for a planned trip, I'm building a charger for it that gets it's power from the 12 volt charging system of my motor home. The sims are basically the same except for the capacitors in parallel with the load, the4r 24 volt battery system.
I've always thought that a battery acted electronically as a very large capacitior and to simulate the charging of a battery, I put a large capacitance in series with battery with a paralell resistor to prevent a simulated over charge which happened with out the resistor.
So, my question is why are the simulation lines so different if the battery acts like a huge capacitor, or am I wrong about that? I realize that SMPSs oscillate according to the size of the charge cap, so I guess the load capacitance doesn’t meld with the charge cap, any comments as to what's happening?
I also noticed that the battery and cap charged quicker with the smaller charge cap.
