Title: Model-based Charging Protocol Optimization for Lithium-ion Batteries • Defined testing protocol for Experimental cell testing for cell characterization and model Parameterization. • Developed a Split ECM model in MATLAB/ Simulink. • Automated the parametrization approach, accelerating model setup for different cell chemistries. • Scaled model from an experimental cell to a 21700 high-power commercial cell. • Reduced charging time by 33% for 0-50% SOC, with no additional degradation.

Department: Battery Research & Technology (GER). Title: Testing & Characterization of cells • Proposed design of experiments for battery/ experimental cells and test plans/scripts preparation for battery cell cyclers. • Worked with environmental chambers and DAQs. • Supported in the planning and execution of electrical and electrochemical characterization tests of experimental cells. • Analysis and presentation of the experimental and full cell test results.

Department: Institut für Werkzeugmaschinen und Betriebswissenschaften (IWB) (Battery Production) Title: Evaluation of the gassing behavior during the formation process of the Li-ion battery production • Manufacturing of Li-Ion Pouch cells on a lab scale. • Characterizing the gassing behavior of different material systems (silicon contents) during the formation process. • Modification of the test bench to increase accuracy of the process. • Evaluation and processing of experimental data using Python.

Department: Hardware Development Title: Hardware Development for 400V/800V Battery Configuration Switch • Setting up a thermoelectric model for a 400V/800V reconfiguration switch. • Evaluation of the simulation results for different current profiles. • Preparing the prototype, setting up the laboratory test bench for practical measurements. (Working with Oscilloscopes and Power supplies for characterization of parameters) • Determination of the operational parameters of the motor for the product.

Department: Industrialization Title: Industrialization of Dual Pole High Voltage Contactor • Supported the development of new concepts for industrializing electro-mechanical products. • Developed understanding of the various phases of product development. • My responsibilities also include conducting incoming quality inspections of prototype parts and preparing documentation for the process, including Standard Operating Procedures (SOPs).
