Preferred Responsibilities Physical Sciences Inc. has an opening in our Imperia Batteries® division for a Battery System Development Engineer. Candidates with strong technical and communication skills are sought who are effective in working in a team environment and have demonstrated an ability to develop battery architectures, select components, and prove the designs meet requirements through analysis. Candidates with experience leading the development of high voltage (>200 V) lithium-ion systems are preferred. Responsibilities include: Requirements & Decomposition: Translate vehicle or system-level targets into specific requirements for cells, modules, battery management systems (BMS), electrical and mechanical interface, and thermal management. Customer Interaction: Prepare proposals and presentations for customers detailing proposed battery designs, anticipated performance, and development plans. Act as the technical expert during the battery development guiding technical development, testing, analysis, and ensuring technical alignment with the customer and intended application. Thermal & Electrochemical Modeling: Simulate heat generation, temperature gradients, degradation mechanisms (like SEI growth or lithium plating), and cell aging. Cross-Functional Integration: Work closely with R&D and production teams to bring concepts from initial prototypes to full production. Testing & Validation: Plan and execute lab protocols for cycle life, thermal stability, vibration, electrical stress, and environmental performance. Root-Cause Analysis: Analyze failure modes, diagnose performance bottlenecks, and implement design updates or safety guard bands. Preferred Technical Skills Include Experience with thermal management systems (air or liquid cooling) and electrical systems integration. Knowledge of safety standards, including the NAVSEA 'S9310 testing process, high current and high voltage safety protocols, and failure modes analysis (FMEA).
