This document defines the metrology requirements for measuring systems that measure transferred energy between stationary conductive direct-current and alternating-current electric vehicle supply equipment and electric vehicles.
This document contains requirements as well as criteria for testing measuring systems.
This document specifies in addition requirements such as for:
- the measurement of the duration of the energy transfer session;
- energy transfer at different tariffs, e.g. rates changing during charging session;
- consideration of cable losses;
- sealing;
- bi-directional energy transfer.
Electric vehicle supply equipment measuring systems (EVSE-MS) as defined in this document are
intended to be used for electric vehicle supply equipment (EVSE) complying such as with IEC 61851-series.
This document does not:
- cover data communication protocols
- specify onboard measuring equipment for rolling stock, according to EN 50463-series and IEC 62888-series The requirements for AC and DC static meters are specified in EN 50470-3:2022 and EN 50470-4:2023.
NOTE This document can be used for other metering applications similar to EVSE, as far as applicable, eg. applications for the electrical energy transfer to vessels.
