Sweden will become a world leader in battery research and electrification of the transport sector. A new collaboration between Chalmers University of Technology, Lund University and Uppsala University will contribute with more research, more engineers and continuous competence development in battery technology and power electronics.The transport sector worldwide is currently switching to fossil-free operation and electrification is the dominant strategy. This has led to an increasing demand for research and expertise in battery development.The Swedish transport sector is in the middle of this green transformation with the goal that the vehicle fleet will be completely fossil-free by 2045, with a reduction of carbon dioxide emissions by 70 percent by 2030. For industry to take a leading role in the transition to an electrified society, new knowledge is needed and skills - applied research, training of engineers and further training of already professionals.
