Research Methodology

Two parallel data streams informed the analysis: structured primary interviews with OEM platform engineers, Tier 1 supplier procurement leads, power electronics engineering directors, and fleet operator holding-company executives; and secondary validation against SEC filings, MIIT new-energy vehicle credit system documentation, vehicle production databases, and customs/trade flow records. Bottom-up unit demand modeling triangulated against top-down market sizing from semiconductor vendor revenue disclosures.

Across the projection horizon, analytical frameworks segmented volume and value by component type, end user procurement model, vehicle application class, and installation integration philosophy. CAGRs derived from regression analysis of historical SiC adoption curves, battery platform voltage migration timelines, and OEM production capacity announcements. Industry-specific forecast inputs included AEC-Q101 qualification pipeline status and MIIT credit system threshold revisions.

The analysis sits within stated boundaries; outcomes outside sustained 800V platform rollout, stable rare earth magnet supply, and continued IRA domestic content enforcement would require recalibration. Forecasts reflect assumptions regarding OEM dual-sourcing preferences and fleet operator consolidation trajectories. Revision becomes warranted when SiC epitaxy capacity expansion crosses thresholds that eliminate current supply constraints.
