PVtec Charger

"Reliable and cost-optimized charging stations and networked new charging solutions for grid-serving and economical charging of electric vehicles with electricity from renewable sources" - PVtec-Charger; Subproject: Mission profiles and thermal monitoring.

Charging solutions for electromobility and corresponding charging stations are currently still characterized by too high costs and still insufficient integrability into the dynamically changing energy system. The aim of the joint project is therefore to achieve interoperable and grid-supporting system integration and a significant reduction in costs while at the same time improving reliability and ensuring all current and future relevant functionalities, future viability, security (especially cyber security), efficiency and resource-saving long service lives.

This is to be achieved by a novel solution approach with a series of technological innovations from inverter and digitization technology as well as a holistic approach from power electronics at the module level to optimal integration into the energy system and worldwide applicability for all system constellations.

The special technological innovation approach of the project is to apply the achievements of photovoltaics and its inverters (economies of scale, costs, quality, reliability, grid integration) to the charging infrastructure and at the same time to develop them further with regard to consistent sector coupling and digitization. In the project, the basic system architectures and technology solutions for scalable applications will be created and novel charging solutions will be realized and evaluated.

At the University of Kassel, the focus is on the investigation of mission profiles for future charging stations as well as thermal monitoring and charging strategies based on this.
