Researchers in Germany have presented a systematic approach to quantify EV battery degradation across various charging strategies. They conducted battery aging experiments under designed conditions that mimic the characteristics of real-world driving and vehicle-to everything (V2X) applications, including vehicle-to-home (V2H) and vehicle-to-grid (V2G).
A comprehensive parameter study was also carried out to explore the intricate relationships between V2X applications and battery degradation. The full paper is available here.
The authors of the study are Jingyu Gong, David Wasylowski, Jan Figgener, Stephan Bihn, Fabian Rücker, Florian Ringbeck and Dirk Uwe Sauer.
The paper explores the V2X concept, focusing on bidirectional energy exchange between EVs and the power grid which, according to the researchers, has potential implications for EV owners, such as reducing energy costs, and the potential to benefit grid infrastructure by increasing renewable energy usage.
