Smart Charging - demand-driven and cost-optimized

Due to the massive market ramp-up of e-vehicles, controlled charging is playing an increasingly important role. Without this "intelligent intervention", the available (connection) capacities will be heavily loaded or, in the worst case, even overloaded when a certain number of e-vehicles are to be charged. This in turn results in the need to expand capacities or pay for energy purchase peaks. But this does not have to be the case: The real laboratory of Fraunhofer IFAM offers the possibility to test and analyze intelligent load and energy management systems for charging infrastructure in combination with storage systems and photovoltaic systems in order to achieve optimal system design and reliable system operation. The real laboratory can be individually adapted and operated to any test scenarios.

The mobility industry is in a state of flux: the number of electric cars on the roads is steadily increasing, and more and more companies are also converting their fleets and company cars to electric mobility. The companies are faced with the question of what technical options are available to provide as many charging points as possible for their employees' e-vehicles with limited (physical as well as economic) building connection power. One answer is to integrate an intelligent charging management system.

But this is not the end of the story: due to the multitude of possible components of a (building) energy system, such as photovoltaic and wind power systems, electrochemical storage systems, heat generators running on hydrogen or other fuels, etc., the digital interconnection of the components as well as the knowledge of the historical as well as forecasted generation and consumption data of these components and the building load is mandatory.

Intelligent charging of electric vehicles

Based on this data, an intelligent charging management system, linked to a local energy management system, can carry out the charging processes of the e-vehicles in the best possible way. The following added values result:

• Maximization of the number of charging points
• Better utilization of the installed components
• On-demand charging with 100% user satisfaction
• Compliance with available (physical or economic) grid connection capacities
• Maximization of own power consumption rate
• Minimization of total costs

Real laboratory at Fraunhofer IFAM

Within the last ten years, Fraunhofer IFAM has built up a real laboratory with different charging stations (27 AC charging points with max. 11/22kW each & 2 DC charging points with max. 50kW each), storage systems (Redox-Flow, LFP, NMC, Pb, ZEBRA; total capacity approx. 200kWh) and photovoltaic systems (capacity approx. 25kWp).

This real laboratory is therefore particularly suitable for grid operators and energy suppliers as well as manufacturers of energy management systems as well as charging stations, storage systems or photovoltaic systems. They can use their products to test their own issues under real conditions. For this purpose, the reallab can be individually adapted and used according to possibility.

With the help of the real lab, Dr. Stefan Lösch's "Smart Energy & Data" group is researching the interaction of energy management systems, charging infrastructure, storage systems and photovoltaic systems.
