I can easily output the files for

"/opt/app/braindata/data/output/OutputBRD/"+'Date for Start of Charge'+".csv"

but not

"/opt/app/braindata/data/output/OutputBRD/"+'Date for Start of Charge'+".brd"

It gives me the following error:
Got Python exception

It is the Unix server that doesn like the "-" in the "2012-01-22" in the string.
Replacing the "-" will export into brd..
It is not the omptimal solution, but it works..

Are you sure there wasn't a file already there?

You are getting a permission denied error, which could arise if the file already existed and you didn't have writes to overwrite it. I am not aware of any known issue with a "-" in the name of a file, and I was just able to produce one myself, using your node.

I suspect there is a previous file /opt/app/braindata/data/output/OutputBRD/2012-01-22.brd already there, that you can't overwrite.

It worked when removing the files.
Thanks!

Now i can run it over and over without any problems, even if there are existing files?

You should be able to, yes. The node can overwrite the files, it was a permission problem with the previous file's existence. So long as you continue to run the graph with the same installation (so the same server "user" is creating and overwriting the file), you should be fine.
