Metrology for electric vehicle charging systems

Electrical Vehicles (EVs) and a growing EV charging system (EVCS) infrastructure are essential to the European Commission’s plans to build a competitive and sustainable transport system by 2050. However, as EVCSs push the limits of energy transfer technology, suitable methods and standards for their evaluation are needed. Traceable

metrological methods, together with harmonised European regulation and standardisation, need to be developed for independent performance evaluation of EV charging systems. This will ensure accurate metering and efficiency and allow the characterisation of grid distortion caused by EVCS under realistic operating conditions.
