This Guide provides guidance on the metrological and technical requirements applicable to Electric

Vehicle Supply Equipment (EVSE, both AC and DC) subject to legal metrological controls. The

requirements are provided for type approval, verification, re-verification and in situ testing. They also

apply to modifications that may be made to existing approved devices. This Guide does not apply to

wireless charging systems.

The provisions set out here apply only to active electrical energy measurements and computation of

transaction billing.

This Guide is structured very similarly to an OIML Recommendation since it is the intention of the

Project Group to transform it into a Recommendation as soon as possible.

This Guide does not apply to contractual private transactions as defined in 2.2.16.3.
