EV Charging Terminology

Derating is the reduction of charger output or performance under certain conditions, such as high temperature, supply limits or component protection. It is normally assessed alongside phase availability, circuit capacity, protective devices, cable sizing and DNO/site constraints.

Diagnostics are the tools, messages, logs or checks used to identify charger faults, performance issues or communication problems. It is normally considered alongside charge point management systems, OCPP support, firmware updates, reporting and remote diagnostics.

Fault indication is how a charger shows that a fault, error or abnormal condition has been detected. It is normally assessed alongside authorisation method, user experience, accessibility, payment flow and support requirements.

ISO 15118-4 contains conformance test specifications for ISO 15118 network and application protocol requirements. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-5 contains conformance test specifications for the physical and data link layer of vehicle-to-grid communication. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

An LED status indicator uses lights or colours to show charger state, availability, fault status or charging progress. It is normally assessed alongside authorisation method, user experience, accessibility, payment flow and support requirements.

Operating temperature is the ambient temperature range within which a charger is designed to function correctly. It is normally checked against mounting method, exposure, durability, access requirements and the conditions at the installation location.

Remote monitoring allows charger status, faults, sessions and performance data to be viewed without attending site. It is normally considered alongside charge point management systems, OCPP support, firmware updates, reporting and remote diagnostics.

A support page is an online manufacturer or provider page for help, technical support, FAQs, downloads or contact routes. It is normally used to keep manufacturer, product, support and procurement information consistent across charger listings.
