Lyten Sweden is seeking a professional Senior Battery Simulation Engineer o join our R&D organisation in Västerås. The Senior Battery Simulation & Modelling Engineer will develop and validate advanced simulation models for battery cells, including performance, degradation, thermal, swelling, and mechanical behaviour. The role supports current NMC products, future battery chemistries, and customer-facing simulation solutions. Key Responsibilities Key responsibilities include (but are not limited to) Battery Model Development Develop and maintain simulation models for battery cells, supporting current chemistry products and next-generation chemistries. Performance Modeling Develop and validate performance models, including ECM-based approaches, to predict battery behavior and support BMS applications. Lifetime & Degradation Modeling Develop and calibrate lifetime prediction models to accurately estimate battery aging, performance degradation, and end-of-life behavior. Thermal Modeling Develop 3D thermal simulation models to predict temperature distribution and support thermal management optimization. Swelling & Mechanical Modeling Develop swelling and mechanical models to predict cell expansion, deformation, and structural behavior throughout battery life. Safety & Venting Simulation Develop simulation models for vent deformation and pressure-related mechanical behavior to support battery safety assessments. Validation & Model Correlation Parameterize, validate, and continuously improve simulation models using experimental and product validation data. Customer Model Delivery Deliver validated simulation models to customers and provide technical support for performance, lifetime, thermal, and mechanical analyses. Cross-Functional Collaboration Work…
