Abstract
As European DSOs advance with smart meter rollout plans, this review assesses the current state and future opportunities for the direct integration of commercial wallboxes for EVs and smart meters in a selected number of European countries. Direct integration is challenging: while wallboxes are sold on international markets and follow recognized standards, smart meters are mostly national or regional products, and grid operators have developed their own proprietary Advanced Metering Infrastructures (AMI). Here, we first advocate the case for direct integration, noting that it is particularly well suited when EVs are the only flexible load in the household, a common situation in Europe, and for implementing flexibility
services based on real-time grid signals. We then review smart meters data exchange protocols and communication interfaces and identify the common issues hindering smart meters exploitation. We eventually propose a set of recommendations to tackle smart metering infrastructures limitations and unlock the identified potential.
