Research Methodology

The Thailand EV Manufacturing Database is developed using a structured, multi-source research process designed to ensure accuracy and consistency across every tracked record.

Step 1: Scope Definition & Universe Mapping

The research team defines the full universe of EV manufacturing facilities to be tracked within scope, drawing on regulatory filings, industry association membership lists, company disclosures, and prior desk research to establish an initial master list.

Step 2: Data Collection & Verification

Each record is populated using primary sources including company announcements, regulatory and permitting filings, government databases, and, where available, direct outreach to operators and developers, cross-checked against secondary sources such as industry reports and trade press coverage.

Step 3: Classification & Standardization

Records are standardized into a consistent schema covering location, capacity or scale, ownership, operational status, and timeline detail, allowing like-for-like comparison across all regions of Thailand.

Step 4: Quality Review & Update Cycle

The database is reviewed on a periodic basis to reflect newly announced projects, status changes, and ownership updates, with the 2026 reference year reflecting the most recent verified data snapshot at time of publication.
