SEOUL, South Korea -- E-mobility, or electric mobility, is projected to mark the next significant paradigm shift in the transportation industry, providing growth opportunities not only for electric vehicle manufacturers, but all service providers in the fields of energy and transport systems. While progress is accelerating in pace and sophistication, some obstacles to EV adoption remain. One of the main issues is that EVs require charging along their journey, and likely at charging stations managed by different charge point operators. To prevent compatibility issues down the road, the Open Charge Point Protocol (OCPP) was established to allow interoperability in EV charging infrastructure and streamline payment processes across mobility operators. With more than 40,000 installations in 49 countries, OCPP has become the de facto open communication standard for open charger to network communications.
