I'm highly interested in your way of designing the charging system,
which I feel is yet the weakest important main point in all(?) the TC
design-tools (including, of course, my own TCplan ). I would be happy to
be within the Beta testers, when you are ready with the program. The
"Design Example" would shurely help to understand the procedure. Keen to
read more from your great developments...

Cheers
