In this work, an energy management system is presented which provides energy-management-as-a-service for electric vehicle fleet operators. Energy production and price forecasts are integrated with near real-time telematics data from a shared electric vehicle fleet, to optimize charging profiles for multiple charging sites of fleet operators. For this purpose, system architecture and a proper optimization method enabling different charging strategies are introduced. The presented system is finally evaluated by real world model trails and an optimization benchmark.enconference paper
