Through the intelligent use of a combination of stationary and specially developed mobile storage systems with optimally coordinated properties, the storage-based integration of renewable sources into the energy supply network and the increased use of emission-free electric vehicles in compaction spaces will be linked and supported in a sustainable and efficient way. For this purpose, four strands of action are defined: 1) The design, construction and integration of a grid-connected stationary energy storage unit with a total power of at least 400 kW, which both as a supply for several DC fast charging stations at any time simultaneously operated (“fast charging station”) 2) The development, construction and the on-board integration of a safe and durable fast-chargeable high-performance lithium-ion storage unit based on LTO technology, demonstrated exemplarily on a test stand that simulates a vehicle type typical of road-bound short-range logistics. Charging times of a maximum of 10 minutes are targeted. 3) The consideration and further development of an efficient integration of the fast charging system with buffer storage into the network environment in order to be able to provide system services for the supply network. 4) Grid measurements and analyses of possible grid connection points shall be carried out by means of grid measurements and analyses of the electrical properties of potential connection points of high-performance charging systems in urban supply areas. The aim is to examine • the potential to avoid network expansion costs, • how the current harmonic load of the grids is and how this changes due to the integration of the charging stations, • whether the inverters/inverters can contribute to the improvement of the voltage quality. These measurements aim to obtain a better understanding of the electrical properties of potential points of connection of charging stations and to reduce the cost of grid integration Essential advantages of this integrated solution can be described as follows: • Structurally supporting/grid stabilising and e-mobility support multiple functionality of the stationary storage module • Reduction of mobility-related pollutant and noise emissions in the heavily polluted agglomerations by the use of fast-charging battery-electric delivery vehicles • Increase the self-use rate of renewable energy • Providing rapid charging stations independent of the availability of high voltage networks, a complete provision of high-voltage charging stations in the area is possible and not only for long-distance roads.
