EV Charging Terminology

A display screen is a visual interface on a charger used to show instructions, status, tariff, payment or fault information. It is normally assessed alongside authorisation method, user experience, accessibility, payment flow and support requirements.

A dynamic QR code is generated for a specific charger, session, user journey or payment flow, rather than being a fixed code printed permanently on the charger. The code can direct the user to the correct session or payment process and may expire after use or after a defined time.
