These folks might have some helpful resources available. I recall an EV day at the Morristown library last April. There were presentations and they had several EVs on display with owners available to answer questions and to share experiences. Don't recall which of these groups sponsored it but I think it was the first.

You might also get some help from the nj dep.

If you let us know the date and other details one or more members of the forum might be able to attend to offer support.
I have given EV presentations to similar audiences on several occasions. Its fun and really is a community service.
Good luck.
