Posición de doctorado sobre segunda vida de baterías para soporte de red

Job Description

While the concept of reusing electric vehicle batteries for grid support is gaining traction, practical implementation remains limited by a range of unresolved challenges. Existing DC charging systems are not designed for the heterogeneous nature of second-life batteries, which differ in state of health, capacity, and interface standards. Furthermore, spatial constraints in dense urban environments, coupled with regulatory uncertainties surrounding battery transport, safety, and installation, complicate deployment. Current assessment frameworks insufficiently capture the long-term reliability, environmental trade-offs, and techno-economic feasibility of second-life battery systems in grid applications. As a result, there is a pressing need for rigorous research to develop integration strategies, modeling approaches, and regulatory frameworks that enable reliable and scalable use of second-life batteries in high-power DC charging networks.

This PhD is funded by Holland High Tech and ABB Delft.

The research in the Department of Electrical Sustainable Energy is inspired by the technical, scientific, and societal challenges originating from the transition towards a more sustainable society and focuses on four areas:

• DC Systems, Energy Conversion and Storage (DCE&S)
• Photovoltaic Materials and Devices (PVMD)
• Intelligent Electrical Power Grids (IEPG)
• High Voltage Technologies (HVT)

The department owns a large ESP Laboratory assembling High Voltage testing, DC Grids testing environment, and large RTDS that is actively used for real-time simulation of future electrical power systems, AC and DC protection and wide-area monitoring and protection. The DC Systems, Energy Conversion and Storage (DCE&S) group is responsible for research and education in the fields of DC systems, high voltage technology, energy storage, electronic power conversion (power electronics), and electromechanics. DC systems is a multidisciplinary field of research, exploring the integration of renewable energy sources and energy storage (electric vehicles) in DC networks and systems and future DC transmission grids. The group is currently active in applications such as Direct Current distribution and transmission grids and microgrids, electrification of mobility (charging of electric vehicles), and renewable generation of electrical energy (such as wind and solar energy). Would you like to know more about the ESE department and the DCE&S group? Please take a look at the webpage www.tudelft.nl/ewi/ese.
