Errors in Battery simulator

I am trying to create this circuit as an example of "ssc_battery_management"... My circuit is this: http://img856.imageshack.us/img856/9189/batrj.png
But i have had some difficulties, as the erros like: "Error setting parameter 'Main branch time constant, Tau1>0': Expected a single string or a cell array of strings." "Error setting parameter 'Resistance, R10': '0' is not a valid unit."
Someone can help me?

You forgot to include the Simscape library files used to model the battery cell. I assume you must have a directory called +LeadAcidBattery with the source files for the R0, R1, R2, etc... Right now, the model won't run because it can't find those files. Can you upload those as well?

I can't run the model Celula.mdl, I get an error message similar to:
Failed to find 'Main Branch Capacitance, C1/Slave_input.R1' in library 'LeadAcidBattery_lib' referenced by 'Celula/Condensador C1/Slave_input.R1'
I am not sure what you did to break it, but what you need to do is generate the LeadAcidBattery_lib by running ssc_build LeadAcidBattery and then use the blocks from the generated library file into the model to replace the existing ones.
I can't run the other models either because I'm missing the file Battery_Management_Lib.mdl.

If you look at ssc_lead_acid_battery, you'll see that in the cell model, there is a thermal model, constructed with the blocks from the Simscape foundation library.

Again, it's difficult to comment without seeing the model. Make sure that you follow the rules in the Simscape documentation for connecting components (help browser -> Simscape -> user's guide -> Modeling physical systems) and read through the documentation to make sure you understand how the software works and how to use it properly.
I would also strongly recommend the following training course:

For these types of problems, you should also contact technical support:

Again, you should really read the documentation, in particular "Setting Up Solvers for Physical Models" (http://www.mathworks.com/help/releases/R2011a/toolbox/physmod/simscape/ug/brsbz56.html) and "Customizing Solvers for Physical Models" (http://www.mathworks.com/help/releases/R2011a/toolbox/physmod/simscape/ug/bsigllk.html).
