3 pos­i­tions - Research Assist­ant - salary grade E13 TV-L Ber­liner Hoch­schu­len

under the reserve that funds are gran­ted - part-time employ­ment may be pos­sible

Research work in the BMBF-fun­ded research pro­ject "Ein­fluss von SiC-Wech­sel­richtern auf die Lebens­dauer von Trak­tions­bat­ter­ien (SiCWell)“ (Influ­ence of SiC Invert­ers on Trac­tion Bat­tery’s Life­time). In cooper­a­tion with indus­trial part­ners, the research assist­ants will invest­ig­ate the effects of fast-switch­ing SiC-based power semi­con­duct­ors on the life­time of the vehicle bat­tery. There­fore, the aim of this research pro­ject is the devel­op­ment of a SiC drive inverter, the invest­ig­a­tion of the SiC power elec­tron­ics’ influ­ence on the load and the life­time of the bat­tery and its com­par­ison with the cur­rently avail­able power elec­tron­ics. Based on these res­ults, the research assist­ants will identify on the one hand optim­iz­a­tion poten­tials in the power elec­tron­ics hard­ware and the con­trol and reg­u­la­tion and on the other hand invest­ig­ate meth­ods for online life dia­gnostics in order to increase the over­all reli­ab­il­ity of elec­tric vehicles.
