International interoperability between Electric Vehicle Service Providers (EVSPs) and Electric Vehicle Supply Equipment Operators (EVSE operators) requests that at least two basic business objects are identified without any ambiguity all over Europe: Electric Vehicle Supply Equipment (EVSE) and e-Mobility Accounts (e-MA). In addition to these two business objects, in some countries it is also considered necessary to uniquely identify EVSE Pools (or also called Areas) to be able to implement specific use cases.
