ESSENTIAL DUTIES AND RESPONSIBILITIES Systems Architecture: Develop and recommend BMS architecture for each family/program to achieve product line harmonization. Maintain and update BMS functional software (SW) and hardware (HW) requirements for battery applications within different ESS architectures. Identify and propose opportunities for harmonizing BMS functional requirements globally, supporting program features and system requirements. Establish best practices for capturing BMS functional requirements, interpreting their impact, and facilitating cross-functional team communication. Provide technical clarification of designs with suppliers and manufacturing. BMS Communication Interface Requirements: Establish BMS communication interface requirements with global alignment opportunities. Create BMS communication interface topology charts and flow diagrams. Identify and suggest enhancements for BMS communication interface requirements. Recommend a process for managing changes in communication interface requirements. BMS Controls Requirements: Develop BMS Controls functional requirements, including contactor control, voltage, current, and cell management controls. Create high-level flow charts and diagrams for BMS controls requirements. Battery Safety Requirements: Develop comprehensive Battery functional safety requirements, covering aspects like thermal propagation, outgas detection, cell pressure sensing, etc. Ensure compliance with corporate and regulatory safety standards. Design high-level functional safety requirement flow charts and diagrams. General Engineering Support: Create robust test plans to achieve BMS Systems deliverables. Support Component Design Failure Mode and Effects Analysis (DFMEA). Assist validation and test teams with strategic planning. Collaborate cross-functionally to verify battery software requirements meet customer needs. Aid software Design Responsible Engineers (DREs) in root cause analysis and best practices. Technical Responsibilities: Maintain a working knowledge of Lithium-based battery cells. Identify and quantify critical battery parameters. Develop a functional understanding of cell behavior based on age and environment. Specify incoming inspection criteria. Develop group controller requirements based on system requirements. Document, specify, and test input and outputs for the group controller. Create system-level boundary diagrams, topology charts, and flow diagrams. Other: Perform other duties and responsibilities as assigned. QUALIFICATIONS B.S. in Engineering with 15 years of experience or M.S. with 10 years.
