Lithium-Ion Simulation Circuit

[shivs]

Hello,

I need to find a way to simulate a Lithium-Ion battery pack. The pack that I have has 3 cells in series(11.1V nominal). I am going into manufacturing of a design which contains a complex algorithm for charging the lithium battery pack (constant voltage, constant current). I cannot use an actual battery pack because it would eventually fully charge. Basically I need a circuit that acts a current sink (charge current from device will be ~200mA) and also has a terminal voltage of ~11V. In the end I want to measure the charge current of each device and verify that is outputting ~200mA.

Any suggestions?

latest versions of matlab/simulink have lithium-ion battery models.

check at my battery model made in verilog-A

If you need 3 of them, just put em in series.

To simulate a Lithium Ion battery, I think you can use a DC Power supply with current sink capability such as Agilent HP6632B...

matlab/simulink do have Li-ion battery model but Temp is not considered as a performance variable, so it may not be accurate.
