From now on, you just have to fire up Google Maps if you need to hunt for an open EV charging station. The latest versions of Google Maps for Android, iOS and the web now show real-time availability for charging ports in the US and UK, giving you a better idea of when to go for a top-up -- you're no longer relegated to static info like before. The feature won't help you find a Tesla Supercharger (you don't really need that given Tesla's app), but it will cover the networks of Chargemaster, EVgo and SemaConnect, with Chargepoint coming soon.
