BESS Battery System Technology:
Translate energy storage application needs into specific BMS, battery module/pack, and rack/system requirements, focusing on electrical, mechanical, thermal, environmental, reliability, and compliance aspects.
Drive the development of energy storage systems that are battery technology-agnostic, allowing for a range of cell chemistries (e.g., Lithium-Ion – NMC, LFP) and pack architectures.
Work with Director of Emerging Technologies to evaluate future battery technologies and qualifying applicability to Fluence’s products.

Supplier and Design Reviews:
Review and assess battery supplier specifications for cells and modules, ensuring alignment with BESS requirements.
Lead technical design reviews and approval for BMS and Battery Packs, ensuring that designs meet all performance, reliability, and safety objectives.
Ensure seamless integration of BMS with battery modules, optimizing for cost, safety, and manufacturability.

Design Validation and Testing:
Oversee the creation and execution of test plans and procedures for BMS and battery pack validation, covering critical performance metrics such as thermal management, charge/discharge cycles, and safety compliance.
Lead FMEA, DFM, and DFA reviews for battery platforms, focusing on identifying and mitigating design risks early in the development process.

Cross-Functional Support:
Collaborate with global R&D teams in addressing technical challenges, leading root cause analysis, and ensuring the resolution of battery-related issues.
Support System-Level Testing for BESS products, ensuring that battery packs perform optimally within the broader energy storage system.
Provide technical support to manufacturing and supply chain teams for supplier development, alternate component qualification, and mass production scalability.
Assist quality teams in root cause analysis and driving corrective actions when issues arise in production or field operations.

Regulatory and Safety Compliance:
Ensure compliance with industry standards and regulatory requirements, including certifications such as UL, IEC, and others related to battery systems.
Lead engineering standards for battery safety design and testing, ensuring that products meet the highest global safety standards.

Technology Adoption and Customer Support:
Work closely with regional business units to drive the successful adoption of battery platforms for BESS products, providing ongoing technical support during product integration and deployment.
Serve as the primary technical point of contact for both internal and external customers on battery-related issues, ensuring smooth communication and issue resolution.
