ER³ Technical Protocol: A Pre-Normative Framework for Risk Interpretation in Confined Energy Systems (v1.2d)

The ER³ Technical Protocol introduces a pre-normative, non-prescriptive framework for interpreting risk in confined energy systems, with particular emphasis on lithium-ion batteries (LIB), electric vehicles (EV), and battery energy storage systems (BESS). ER³ treats risk as a sociotechnical condition arising from the inseparable interaction of three axes: (1) Energy Regime, (2) Confinement System, and (3) Human Decision-Making Capacity. The protocol focuses on how misalignment across these axes acts as a primary risk multiplier, including scenarios of apparent stabilization followed by delayed reactivation. ER³ does not propose suppression methods, design rules, or compliance metrics; instead, it provides an interpretive lens to improve framing, communication, and decision coherence across lifecycle phases. ER³ is complementary and orthogonal to standards and experimental classifications (e.g., ISO 3941:2026, Class L): while such frameworks categorize fire behavior after ignition, ER³ supports upstream interpretation of system conditions prior to and throughout the lifecycle, clarifying the context in which normative tools become relevant.This document is presented as a pre-normative, interpretive framework intended to support critical analysis, discussion, and iterative refinement, rather than to prescribe design rules, compliance criteria, or operational requirements.
