There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community/
https://mapcomplete.org/ is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
Not OSM or Open Source but "A Better Route Planner" (ABRP) was one of the first good EV routing apps and got pretty popular.
Especially early on it was often smarter than the built-in routing systems if the car even had one.
Also available as a website: ABRP
I like the app or website called "A Better Route Planner". It lets you set up your vehicle and select what your criteria are for chargers. For instance, I like to make sure there are at least 2 charging units in case one is out of order.
Never been in an electric car which couldn't do this by itself. Tesla, BMW, Polestar: all had this functionality built-in.
I don't know what the situation stateside is but here in the EU this is standard EV functionality.
We have a fiat 500E which does not have this. Also because it is imported from the US so the whole navigation doesnt work in europe.
Can't exactly remember which car it was but some of the early and smaller EVs didn't necessarily come with a navigation system. Think along the lines of Chevy Bolt or Nissan Leaf.
