Abstract
Power generation and distribution to electric vehicle charging points requires investment in the energy sector and infrastructure. Studies show that the expansion is technically and financially possible. The prerequisite is that charging infrastructure and electric vehicles support intelligent and dynamic load management.
A communication system that connects all partners in the system supports the implementation of the functions for successful grid integration: charging and load management, authorization, payment systems, bidirectional charging, e-roaming and value-added services. For all interfaces existing in the overall e-mobility system, there are standards for communication protocols that support the above functions through the specified messages and data elements. In this way, tariff tables, maximum possible charging power can be transmitted and the desired scheduling for the charging process can be communicated by the vehicle.
Efficient solutions for intelligent load management take into account local as well as temporary conditions, e.g. residential area/parking garage, temporal availability of green electricity. Optimizations can be implemented locally through suitable parameterization. Availability and demand of electricity are in balance.
