Standards Development
This standard provides metrological and technical requirements applicable to Electric Vehicle Supply Equipment (EVSE, both AC and DC) metrological measurements. The requirements are provided only for in-situ (field) testing. They also apply to modifications that may be made to existing in-situ devices.
This standard does not apply to wireless charging systems.
The requirements of this standard apply only to measurements and computation of active electrical energy of transaction billing of in-situ EVSE.
This standard does not provide requirements of when to perform such measurements, or how to enforce in-situ metrology, this is for country (or local) specific regulation authorities.
Electric vehicle supply equipment (EVSE) is an essential to the global rollout of the electric vehicles and decreasing reliance on fossil fuels. Commercial transactions on publicly accessible EVSE require accuracy in measurement of both the quantity of pow er delivered to the customer and the cost of the transaction.
Assessment of the accuracy of an in-situ EVSE’s measurement of energy, and transaction costs, are vital for compliance with local and regional metrology regulations, consumer protection and market confidence in the EV charging ecosystem. In order to allow efficient conduct of such testing on tens or hundreds of thousands EVSE in the future, reproducible measurements and methods need to be defined. This includes the definition of the load points to be tested.
