High Efficiency High Performance 48 V Drive System for Future EV

Electric powertrains are well underway to replace internal combustion engines and become mainstream in the automotive industry. So far, they mostly operate at voltages of 300–800 V.

We now have strong evidence indicating that a 48 V powertrain could be a much better choice for future electric vehicles in terms of efficiency, performance, safety, and cost.

Based on the promising results of the FFI concept study, the aim of this project is to design, prototype and test, both a high efficiency high performance 48 V motor drive concept, and a series-charging parallel-driving battery pack concept.

The project outcome will be used to convince academia and industry that the new paradigm is advantageous, and the shift can be implemented using existing mature technologies. The two-year project starts from 1st of January 2021. Mid Sweden University will conduct the design and prototype part of the project, while STT Emtec will be responsible for building the drive test cell and perform tests.
