Seven-layer socio-technical EV navigation software platform feasibility and appropriateness protocol v1

The proposed seven-layer taxonomy demonstrates methodologicalapplicability as both a diagnostic and comparative benchmarking instrument,enabling transparent cross-platform evaluation while preserving contextualsensitivity to infrastructure-constrained environments. The results indicatethat effective EV navigation assessment extends beyond routing precision to theinteraction between technical performance, user behavior, infrastructurerealities, and policy structures, thereby supporting informed platformselection, capability gap identification, and adaptive deployment strategieswithin evolving electric mobility ecosystems.
