Data and code for Δt(Q)-based analysis of DC–AC charging

This repository contains representative datasets and Python scripts used to reproduce the Δt(Q)-based analysis and regime mapping presented in the associated manuscript. The workflow includes:1. Extraction of τ_ref from HPPC descriptor data2. Computation of Δt(Q) using strict signed-net integration3. Construction of (Π, κ) regime maps and Figure 1 The Δt(Q) framework enables state-equivalent comparison of charging processes and reveals the decoupling between event-level acceleration and actual state progression. All scripts and data are provided to support reproducibility of the analysis.
