Hi... I have construct a circuit that uses the energy of a PV cell to utilize in charges and/or to charge a battery. My model is the next, but i have a problem in connect my charge to a circuit... What is my error?

Can you accept an answer and create a new question rather than keep appending to this one? Also, please provide more details: which battery? In SimPowerSystems? under which conditions? etc...

You can't connect Simscape and SimPowerSystems components together, Have a look at this thread and that thread on the newsgroup for more details.

You're measuring the current on the Simscape side and applying on the SimPowerSystems side with a controlled current source. That's correct, but to get the interface correct and complete, you also need to measure the voltage on the SimPowerSystems side and apply it on the Simscape side with a controller voltage source. Note that this will likely introduce an algebraic loop in your model, that you may need to break with, say, a low-pass filter (transfer function) with an appropriately chosen cut-off frequency.

Not quite. You need to measure the voltage on the SimPowerSystems side, not the Simscape side, and inject it on the Simscape side with a controlled voltage source. Basically, if you measure current on one side, you need to measure voltage on the other, and vice-versa.

You need to measure the voltage on the SimPowerSystems side using a voltage measurement block from SimPowerSystems, not Simscape:

You can then apply that voltage on the Simscape side using a controlled voltage source from Simscape:

The input signal goes into the signal port (S), the + and - ports are electrical ports.

Yes!! Although you appear to have grounded the + terminal of the battery. Is that what you intended to do? In other words, is your current source in the right orientation?

dear Nuno, can you send me this circuit as i stuck in the first part of doing the signal builder, and also the value. My email address is shermonsheran@gmail.com kindly please help me, i'm doing battery charger project. thank you
