New project could slash EV charging times with 1000V high-voltage tech

A new EU-funded research project called ODYSSEV, launched in early 2026 and involving Dortmund University researchers, aims to drastically reduce electric vehicle (EV) charging times by advancing high-voltage technologies beyond 800 volts, targeting voltages over 1000V. These higher voltages enable ultra-fast charging through thinner cables, which reduces vehicle weight and energy losses, making EVs more practical and appealing to consumers. The project addresses the technical challenges of operating at such high voltages, including enhanced insulation requirements, semiconductor limitations, and battery thermal management during rapid charging. ODYSSEV spans the entire development chain, from creating innovative semiconductors and high-performance power modules to integrating these into key EV components like on-board chargers, traction inverters, and a specially designed electric motor. The project also involves developing a reconfigurable battery pack to form a scalable, efficient drive system. Using advanced modeling and simulation, the team aims to optimize designs before physical prototyping, saving time and costs
