Digital Configurator for DC Charging Infrastructure Design

KEBA Mobility has introduced a structured online configurator for the design and sizing of direct current (DC) charging infrastructure. The system is aimed at corporate fleet operators, Charge Point Operators (CPOs), and installers, enabling the definition of the technical requirements necessary for applications in public hubs, commercial fleets, and destination charging sites.

Sizing Parameters and Power Calculation
Designing a DC charging infrastructure requires analyzing power requirements, fleet composition, and spatial constraints. The software processes these parameters to identify the appropriate hardware configuration within the direct current component portfolio. The calculation system covers applications for light vehicles, commercial vans, and heavy-duty trucks, optimizing power distribution based on local power grid capacity and the users' operational needs.

Charging System Architecture and Hardware Topologies
The hardware architecture proposed by the system encompasses several charging topologies. The KeContact DCU10 unit functions as a centralized power system designed to simultaneously supply distributed charging points. For independent configurations, the KeContact DCA10 model operates as a high-performance charging station. Both systems adopt rectifier-based power modules and support integration with backend management platforms via standard protocols.

For applications where alternating current (AC) charging is insufficient but the grid requirements for high-power fast-charging stations are not met, the KeContact DCW15 unit provides 40 kW in a wallbox format. This configuration allows light vehicles and vans to replenish their energy within a two-to-three-hour window, limiting the peak power demand on the infrastructure and containing installation costs.

Operational Reliability and Telematics Diagnostics
The hardware components are built according to industrial regulatory standards to withstand thermal load cycles and harsh environmental conditions, ensuring the operational continuity essential for commercial fleets. The systems integrate interfaces for telematics monitoring and remote diagnostics, reducing downtime through the preemptive identification of technical anomalies. Alessandro Govi, Sales Director of KEBA Energy Automation GmbH, specifies that the software adopts a modular and scalable approach to align the designed infrastructure with current requirements and support subsequent expansions linked to the evolution of electric mobility.

Additional Context: Technical Specifications and Comparative Analysis
In the electric vehicle infrastructure sector, the use of digital configuration tools represents an operational standard employed to optimize preliminary engineering phases. The 40 kW DC wallbox stations occupy an intermediate technical segment between 22 kW AC stations and ultra-fast systems exceeding 150 kW. This segment, which also features equivalent solutions developed by manufacturers such as Delta Electronics and ABB, is designed to provide charging times compatible with the operational breaks of urban logistics. This avoids the need to install additional medium-voltage transformers, which are typically required for High Power Charging (HPC) architectures.
