IEC 63119

IEC 63119 is an international standards family for information exchange used in EV charging roaming services. It describes interaction between charging service providers, charging station operators and clearing-house platforms through roaming endpoints. IEC 63119-1:2025 is the current general part and replaced the 2019 edition. The 2025 revision expands roaming roles, adds CDR terminology and updates the security stack to TLS 1.3. IEC 63119 does not define vehicle-to-charge-point communication or the station-to-operator interface. Those functions sit elsewhere in the charging architecture.
