Project H2EASY - H2 integration in electric drive systems successfully completed
A step-up converter with 160V input voltage, 1000A maximum input current and an output voltage of up to approx. 800V was successfully put into operation just in time for the end of the project, which was carried out jointly with partners SUMIDA, E-Stream, HELLA and BMW.
Thanks to a comprehensive design strategy for the components used, a very high efficiency of just over 99% was achieved at some operating points (despite a high transformation ratio of almost 3 - approx. 220V -> 650V) and a volume of 20 liters (almost 25% below the already ambitious target). In addition to the main task of adapting the voltage of the fuel cell (below 400V with low dynamics) and the drive (400V to 800V with high dynamics), the DC/DC converter can also take on condition monitoring tasks with regard to the fuel cell with slight adjustments.
The goal of optimizing the energy conversion chain between fuel cell, battery and vehicle drive through highly compact and efficient power electronics was implemented by an enthusiastic project team. The project was funded by the Federal Ministry of Transport and Digital Infrastructure (BMVI), supported by Project Management Jülich (PTJ) and accompanied by NOW GmbH.
