Illinois is offering up to $3000 per station installed at workplaces, but it is a Illinois state refund, and not Federal. So, unless you are driving to Illinois to work during the day (as some of my co-workers do), this info is useless to you. However, as a long term plan, maybe you could contact the Wis. state legislation, and prod them a little saying other states are offering some type of rebate program to businesses for installing charge stations??
I just re-read your post....Maybe this info would be helpful during your presentation.
I believe the Illinois rebate states your charge station must be installed and operational by June or July of this year. So, the program is ending soon.
