The BC Hydro EV app indicates when BC Hydro chargers are in use or available.
The PlugShare map and mobile app can be used to find information about the availability of all other chargers.
This is an international crowd-sourced tool that's updated by EV users who voluntarily contribute. Like any crowd-sourced tool, the information may sometimes be out-of-date, but users often indicate when a charger is unavailable.
You don't need to register to use PlugShare unless you'd like to check in at a charger location and leave notes for others.
