Electrical digital twin of low voltage electrical systems to optimize the operating strategies and LV battery size. To decrease the time to market of products, systems or vehicles, it is necessary to reduce the development effort. For this reduction, some parts of the development will be done completely virtual with a digital twin. One part of this virtual development is the simulation of the electrical system and it's behaviour. YOUR RESPONSIBILITIES: Investigation and modelling of low voltage components in vehicle. Investigation of different operating strategies/ use cases. Model setup of low voltage system with all relevant components. Running the simulation with different parameters and use cases. Documentation and interpretation of the results of the different simulation runs. Compare the simulation results with available measurements of the existing system. All findings will be documented into a workflow and processes.
