The project "Intelligently connecting and managing electric charging infrastructure in Baden-Württemberg" (eLISA-BW) was funded by the Baden-Württemberg Ministry for the Environment, Climate Protection and the Energy Sector as part of the Intelligent Network Connection of Car Parks and Underground Car Parks (INPUT) funding call. During the course of the project, an intelligent charging management system was implemented in the Waldhornstraße car park in Karlsruhe. The Karlsruhe Regional Council uses this car park for its fleet vehicles. As this car park is becoming increasingly electrified, an expansion of the electric charging infrastructure is inevitable. However, the grid connection capacity is too low to enable simultaneous charging of all vehicles. By intelligently linking the booking system, the identification interface at the charging station and the continuous measurement of the grid connection power, it was possible to develop a charging control system that charges the fleet vehicles in line with demand and the grid.
