Future Developments in OCPP and ISO 15118 Standards

This guide outlines the future developments in the Open Charge Point Protocol (OCPP) and ISO 15118 standards, which are critical for enhancing the electric vehicle (EV) charging experience. It details the two primary digital conversations that occur during the charging process: communication between the vehicle and charger, and between the charger and network operator. The document explains the significance of these protocols, including DIN SPEC 70121 and ISO 15118, and their roles in facilitating seamless charging experiences. It highlights the ongoing upgrades from ISO 15118-2 to ISO 15118-20 and OCPP 1.6J to OCPP 2.0.1, emphasizing the need for interoperability and the challenges faced during this transition. The guide also discusses the importance of digital communication systems in addressing common challenges within the e-mobility sector, ultimately aiming to improve the reliability and scalability of EV charging solutions.
