Degradation-aware AC battery architectures for high-power charging infrastructure in electrified transport

Research Project, 2027 – 2028

The transition to fossil-free transport requires large-scale deployment of high-power charging infrastructure for electric vehicles, buses, and heavy-duty freight. However, fast charging and demanding transport duty cycles can accelerate battery degradation, increasing lifecycle costs and affecting the sustainability of electrified transport.

This project will develop degradation-aware reconfigurable alternating-current (AC) battery systems for high-power charging infrastructure. It investigates how modular AC-native battery architectures can enable more flexible and ageing-aware battery operation in charging depots. The work combines battery modelling, control engineering, power electronics, experimental prototype validation, and techno-economic assessment at Chalmers, with international collaboration through a Marie Skłodowska-Curie Staff Exchange project. The project will deliver new control methods, experimental evidence, and system-level assessment tools for more sustainable battery operation in fast-charging infrastructure.
