Public chargers are often registered on a software network. For example, the Chargefox network of public chargers are accessible through a smartphone app or using RFID cards.
Networks like these make it easy to find chargers and pay for your charging time. Generally speaking, no public charger will be rated for less than a Level 2 AC station (~7 kW). This means you can expect at least 30 km of range added per hour of charge.
It is considered impolite to leave a fully charged EV in a charging bay for extended periods. Please use public bays only when you intend to plug in and charge with them.
more than that, especially after long trips, may take longer than an entire night with a portable cable. For this reason, JET Charge recommends having an AC charging station installed for home charging.
