Success means the team consistently identifies inflection points in cell pricing, supplier health, and policy enforcement weeks or months before they surface in earnings calls, annual surveys, or trade press. The commercial mechanism is internal-first: the publication proves itself as a decision tool inside the organization, then extends to paid subscribers and a practitioner community as upside. Revenue follows utility — if the team makes better-timed procurement calls and competitive assessments because of what they read here, the publication earned its place. [Read on the website]() ## Issue 2 — Qualification Pack-level requirements, test conditions, and standards by application ### The Standards Map - [The Standards Map — Humanoid Robotics]() — By [Ronan Adike]() · Published 2026-06-09 · Format: The Standards Map No governing standard exists for humanoid robot battery pack qualification. Nine of ten parameter classes on this card trace to borrowed baselines from industrial equipment standards that assume fixed orientation, moderate C-rates, and steady-state duty cycles. A bipedal robot violates all three assumptions simultaneously. Every borrowed threshold, every structural mismatch, and every void is documented here with sourcing tier labeled inline, so your DVP entry traces to something defensible or explicitly records that nothing defensible yet exists. ### Phase Dashboard Pack-level qualification standards across battery applications are at different phases of the same maturation process: settled convention (drones), regulatory abundance without convergence (eVTOL), institutional opacity (UUV/subsea), outright absence (humanoid robotics). The DVP risk in each phase looks different but works the same way. Engineers cite the standard they can find, and the distance between that citation and the structure that actually governs is where untracked program exposure accumulates. Five cards below map where each domain sits as of June 2026. Every claim traces to a cited source and sourcing tier. Where no authoritative standard exists, the void is named. Where a framework is borrowed from an adjacent domain, the borrowing is labeled. A DVP built on unlabeled borrowing carries undocumented risk, not conservative margin. - **IEC 62619 Governs Industrial Drone Packs by Convention** — [Source]() — Published 2026-06-09 Tag: Drone Packs IEC 62619:2022 is the working baseline for industrial UAS pack qualification. UAS does not appear in the standard's enumerated scope. The application is Tier 3 industry convention, not standard text. ASTM F3005-22 covers sUAS; UN 38.3 applies for transport. DVP entries citing 62619 should label the scope inference explicitly. - **DO-311A Alone Misrepresents the eVTOL Qualification Structure** — [Source]() — Published 2026-06-09 Tag: eVTOL Certification Three documents, two jurisdictions, no single name. DO-311A provides the baseline but was scoped for avionics batteries. EASA MOC VTOL.2440 requires non-propagation AND containment (both mandatory, not alternatives). FAA AC 21.17-4 (July 2025) adds performance-based criteria. No TSO/ETSO covers propulsion battery systems. The DVP must name this composite structure. - **Subsea Pack Qualification Has No Unified Governing Standard** — [Source]() — Published 2026-06-09 Tag: Subsea Qualification Commercial programs stack MIL-STD-810 (environmental), API 17F (subsea equipment), and UN 38.3 (transport). For submarine-deployed AUVs, the binding gate is WSESRB approval: a Navy process, not a published standard. Li-ion PPR is Navy-designed architecture, not a codified spec. Commercial programs have no access to this path. The stack must be assembled from scratch, gaps documented. - **Humanoid Robot Packs Have No Qualification Standard** — [Source]() — Published 2026-06-09 Tag: Humanoid Robotics Nothing exists at the pack level. Borrowed adjacent frameworks: IEC 62619:2022 (industrial safety baseline), ISO 13482 (service robots, FDIS in approval, contains no battery pack thresholds), ISO 10218:2025 (defers hot-swap thermal management to manufacturer guidelines). None of these set pack-specific test parameters for bipedal platforms. Every DVP entry here is a documented defensible call. - **62619 Versus 62133-2 Is a Category Boundary** — [Source]() — Published 2026-06-09 Tag: Scope Boundary Industrial (IEC 62619:2022, second edition, May 2022) and portable (IEC 62133-2:2017) have materially different scopes. Applying 62133-2 to industrial drone packs or humanoid robot packs built for sustained high-discharge and field maintenance is a category error. 62619:2022 replaced the 2017 first edition. Verify application profile before citing either standard in a DVP. ### Technical Evidence Base - **Challenges and Key Requirements of Batteries for Electric Vertical Takeoff and Landing Aircraft** — [Source]() — Published 2026-06-09 Penn State/EC Power, DOE- and USAF-funded. Establishes pack-level baselines: 157–200 Wh/kg pack gravimetric energy density at 0.8 GCTP ratio, >2,000 fast-charge cycles with asymmetric temperature modulation (ATM), and 1,600+ equivalent full cycles per year operational throughput. Tier 3: published engineering analysis, not a governing standard. Why is this the default citation? Most-referenced eVTOL battery analysis in the literature. The quantitative baselines here are where most DVP cycle-life entries trace back to. What gets lost in citation? The >2,000 cycle claim requires ATM thermal management as a test condition. Citing this figure without specifying thermal protocol overstates baseline chemistry performance. - **Lithium-Ion Battery Power Performance Assessment for the Climb Step of an eVTOL Application** — [Source]() — Published 2026-06-09 ORNL tested commercial cells under simulated eVTOL climb: 15C pulse for 45 seconds followed by C/3 cruise at 30°C. No cell survived beyond 100 cycles. Post-cycling electrode analysis confirmed anode lithium plating as the failure mode. Partial capacity recovery at low rates did not prevent failure on high-rate reapplication. Tier 3 source. How bad is the gap? First published experimental cycle life under eVTOL climb loads. The <100 cycle result quantifies the distance between current chemistry and commercial requirements. Where does SOH monitoring fail? Capacity fade alone misses this failure mode. Polarization evolution under high-rate conditions requires separate tracking in the DVP. ### The Classification Dependency - [Humanoid Robot Pack Qualification Has No Governing Standard Because the Robot Has No Governing Classification]() — Published 2026-06-09 Which pack standard governs a humanoid robot depends on what a humanoid robot *is*, regulatorily. Nobody has answered that. ISO 10218:2025 covers industrial robots, borrowing IEC 62619 as battery baseline. ISO 13482:2014 covers service robots but references no pack standard. Consumer product classification invokes IEC 62133-2, a scope mismatch for packs running 10–50C pulses. ### Source Trail - **FAA AC 21.17-4: Performance-Based Certification for Powered-Lift Battery Systems** — [Source]() — Published 2026-06-09 FAA's performance-based approach prescribes no specific test standard, so DVP teams must justify their own test matrix from scratch. - **EASA MOC VTOL.2440: The AND Requirement for Thermal Runaway** — [Source]() — Published 2026-06-09 Best public walkthrough of EASA's mandatory non-propagation AND containment requirement, and why it diverges structurally from DO-311A. - **IEC 62619 vs. IEC 62133-2: Sorting the Scope Boundary for Industrial Drone Packs** — [Source]() — Published 2026-06-09 Correctly flags that IEC 62619 application to industrial drones is procurement convention, not something the standard's scope text actually mandates. - **Humanoid Robot Safety Standards in 2026: The Battery Qualification Void, Documented** — [Source]() — Published 2026-06-09 Confirms that hot-swap battery thermal management defaults to manufacturer guidelines under ISO 10218:2025; no pack-level qualification floor exists. - **L3Harris Li-Ion AUVs for Submarine Deployment: WSESRB as the Actual Gate** — [Source]() — Published 2026-06-09 Documents that the binding qualification gate for submarine-deployed AUV batteries is WSESRB approval, a Navy process with no published standard equivalent. - **EASA MOC-3 SC-VTOL Issue 2: Primary Source for Propulsion Battery TR Compliance** — [Source]() — Published 2026-06-09 Tier 1 source establishing the two-approach thermal runaway framework, catastrophic failure classification for propulsion packs, and confirming no ETSO exists. ## Other sections in Issue 2 - [Signal]() - [China]() - [Korea]() - [The Log]() - [Defense]() ## More - [Publication guide]() - [Issue archive]()
