Put the skills you have acquired during your studies into practice and complete your final thesis with us. Uninteruptable Power Supplies (UPS) secure the power delivery to critical electrical equipment by supplying during an outage or grid instability from a backup battery. Typically, Lead Acid or Nickel Cadmium batteries are used as backup battery. They contain high toxic substances which are very critical to the environment and difficult to recycle. Salt batteries (SMC) are non-flammable, free of toxic material and 100% recyclable batteries. They become now very attractive to replace former mentioned toxic batteries. The SMC battery contains an own power conversion system with a battery management system and a digital interface for monitoring and control. The thesis should address the integration of an SMC battery into an existing uninterruptable power supply structure and system The bus coupling to the communication module of the UPS and forwarding to an existing display an existing display should be implemented For the parallel operation of multiple modules a parallel HUB is to be designed as well The thesis is subdivided into a problem introduction, concept, design, implementation and verification section The thesis is coached by our senor staff and implemented in our laboratory in cooperation with the university Ability to work in a team and good communication skills Ongoing studies with a focus on electrical engineering Openness and flexibility to challenges Ability to organize independently Ability to work independently and conscientiously An innovative, global company that combines tradition with modernity A modern team We deal with the future technologies of tomorrow, with your work you can help shape them in a groundbreaking way Exciting tasks in the field of energy supply (from classic areas to the energy transition) Excellent working atmosphere and adequate space for your ideas; it is explicitly desired that you contribute actively A positive welcome culture and excellent induction by our experienced colleagues Large canteen with a wide selection on the company premises Fruit and water are always available free of charge
