Energy Supply and Transmission Systems

Intelligent supply concepts and charging infrastructure from a single source

Increasing demands on energy efficiency, the expansion of renewable energies, and the increasing electrification of vehicle fleets are presenting companies and municipalities with complex challenges. In addition to a reliable supply, energy flows must be intelligently controlled in order to absorb peak demand, ensure grid stability, and reduce costs.

Intelligent energy supply and transmission systems offer decisive advantages in this regard: Precise load forecasts, effective load management, and the recovery of braking energy increase overall efficiency. Energy storage systems buffer surpluses and release them as needed, which improves supply security and cost-effectiveness.

From fleet vehicles to trucks and ferries to work machines, charging infrastructure plays a key role, especially for professional users of mobile, battery-powered applications. Automated charging systems transfer large amounts of energy in the shortest possible time, with minimal operating effort and seamlessly integrated into the workflow.

Working hand in hand with partners from industry and science, the experts at Fraunhofer IVI develop customized solutions based on detailed requirements analyses and in-depth experience in the development of disruptive technologies – for cost and energy-efficient systems that are ready to meet the e-mobility challenges of the future.
