Electric mobility - Measuring systems for supply equipment

Scope

This standard defines the metering-related and system-related minimum requirements for devices that measure energy and time for stationary conductive direct-current and alternating-current supply equipment, such as those in accordance with IEC 61851, in the supply of electricity to non-stationary electrical equipment e.g. electrical vehicles.
This standard specifies terms and definitions, configuration and requirements. It contains minimum requirements as well as criteria for evaluating measuring system. The purpose of the standard is to detail requirements for measuring systems for stationary supply equipment’s in support to the MID (directive 2014/32/EU), especially regarding:
• Delivery point (usually the Plug (IEC 62196), not the terminals of the meter) (MID Annex I No. 7.2 & Annex V No. 3)
• Protection against corruption (MID Annex I No. 8.)
• Indication of result (MID Annex I No. 10.)
• Durable proof of the measurement result and the information to identify the transaction (MID Annex I No. 11.2.)
• Further processing of data to conclude the trading transaction in the absence of one of the trading parties (MID Annex I No. 11.1.(b))
The term minimum requirements means here that more extensive requirements may result from technical rules and legal regulations.
This standard does not cover the requirements from the IEC 61851-series and IEC 63110-series. This standard does not apply to measuring equipment for rail vehicles, according to EN 50463 -series and IEC 62888-series.This standard does also not apply to the requirements for the AC and DC meter itself, which is specified in EN 50470-3 and prEN 50470-4, respectively.
