Search for "ChargePoint" or "charging station" and Apple Maps displays badges to show you the location of ChargePoint stations. Tap on a ChargePoint badge and you'll be able to get directions, see hours of operation and, if available, pricing information. The badge also tells you if a station accepts Apple Pay and, if it does, you will be able to start charging your vehicle and pay using your iPhone.
There are different types of charging connectors for electric vehicles. I popped around Apple Maps to check out various ChargePoint stations in the greater Boston area and discovered that this information isn't displayed on the info panel for a station in Maps. It is, however, a tap away. Tap the More info on ChargePoint link and Maps kicks you over to a ChargePoint page in Safari with details on the types of connectors that station offers.
Earlier this year, Apple teamed up with Parkopedia to add parking information, including spots with EV chargers, to Maps.
