Development of an Avionics Battery System for a 1.5‑Ton Class AAM Aircraft
Project Duration: August 1, 2023 – December 31, 2024
Lead Organization: LIG Nex1
Role: System Architecture, Pack Development, and Flight-Grade Reliability Verification
Project Overview
This project focused on the development of a dedicated avionics battery system for a 1.5-ton class Advanced Air Mobility (AAM) aircraft, addressing the critical need for redundancy, fail-safe operation, and electrical stability in flight-critical subsystems. The system was designed to meet aerospace-grade reliability and safety requirements for next-generation AAM platforms.
My work involved leading the system architecture and ensuring seamless integration with the aircraft’s avionics environment, with an emphasis on modularity, thermal protection, and in-flight operational continuity.
My Contributions
- Designed a fault-tolerant battery system architecture for avionics-only power delivery
- Selected and validated high-reliability cells with embedded protection logic
- Led pack fabrication, environmental testing, and EMI/EMC resilience verification
- Managed documentation and validation aligned with aerospace standards
Outcomes
- Delivered a fully integrated avionics power system with flight-grade redundancy
- Validated thermal and electrical stability under simulated flight conditions
- Strengthened Korea’s AAM infrastructure with avionics-level battery technology
