EV Charging Terminology

GB/T Charging Standard refers to Chinese national recommended standards used for conductive EV charging, including requirements for AC and DC charging connections and associated communication. In EV charging, the term is commonly used to describe the Chinese charging interface and protocol ecosystem, including the GB/T 20234 series.

IET 01:2024 is a non-statutory IET standard and technical specification for Open combined Protective and Neutral conductor Detection Devices used with EV charging equipment. It sets out definitions, requirements and tests for how discrete or integrated OPDD functions should respond to open PEN conductor faults.

Internal PE breakage refers to a charger design where the charger has a means of interrupting or isolating the protective earth path internally as part of its response to a detected PEN fault condition.

ISO 15118 is the international vehicle-to-grid communication standard series covering EV-to-charger digital communication, Plug & Charge, smart charging and bidirectional charging functions. In the UK it is increasingly relevant to future-ready public, fleet and V2G-capable charging systems.

ISO 15118-1 defines general information and use cases for the vehicle-to-grid communication interface. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-10 specifies requirements for wireless power transfer communication within the vehicle-to-grid communication framework. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-2 specifies network and application protocol requirements for EV-to-EVSE communication. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-20 is the second-generation vehicle-to-grid network and application protocol standard, extending support for advanced smart charging and bidirectional power transfer. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-3 covers physical and data link layer requirements for vehicle-to-grid communication. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

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.

ISO 15118-6 covers wireless communication general information and use cases within the vehicle-to-grid communication framework. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-7 defines wireless communication requirements for network and application layers in the vehicle-to-grid communication interface. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

ISO 15118-8 covers wireless communication physical and data link layer requirements for vehicle-to-grid communication. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.

The Measuring Instruments Directive (MID) is the EU framework for placing regulated measuring instruments on the market, including active electrical energy meters used for trade. In EV charging it is relevant to EU market billing, kWh measurement and legal metrology requirements.

The Measuring Instruments Regulations 2016 (MIR) are the UK regulations covering legally controlled measuring instruments, including active electrical energy meters used for trade. In EV charging they are relevant where measured kWh values are used to calculate charges, payments or rewards.

OZEV Commercial refers to eligibility or listing status for UK workplace, commercial or infrastructure-related EV chargepoint grant schemes administered by the Office for Zero Emission Vehicles.

OZEV Domestic refers to eligibility or listing status for UK domestic EV chargepoint grant schemes administered by the Office for Zero Emission Vehicles.

PAS 1899:2022 is the UK accessible charging specification covering the design of public charge point environments, charger placement, physical accessibility and user information. It focuses on making public EV charging more usable for disabled and older drivers.

The Public Charge Point Regulations 2023 are UK regulations for public EV charge points covering contactless payment, payment roaming, price transparency, open data, helplines and rapid charge point reliability. They apply to relevant public charging provision across the UK.

A UKCA Declaration is a declaration that a product meets the applicable Great Britain requirements for placing that product on the GB market. In many cases, this declaration can be issued by the manufacturer themselves, depending on the applicable regulations and conformity assessment route.
