Mapbox recently announced an EV Charge Finder API. It allows anyone to make mapping software (web, app, in-car, etc) with route planning that's EV friendly. It'll take into consideration the terrain and your car and give you an approximation on how much energy that route will use. The API can also display any chargers along the route too. It's basically A Better Route Planner, but an API. Dunno where it sources its charger location and other information from and Australian geography isn't supported yet, but very cool either way. The EV stuff is still in private preview, but you can play around with it a little in the Mapbox Studio. Here's some documentation.
