Thailand has secured more than USD4.1 billion in investment commitments across 198 electric vehicle (EV) supply chain projects, further strengthening its position as Southeast Asia’s leading automotive manufacturing hub. According to the Thailand Board of Investment (BOI), the investments cover battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery production, critical components and EV charging infrastructure, supporting the country’s long-term transition to electrified mobility.
The investment programme reflects Thailand’s strategy of developing a diversified EV ecosystem across multiple propulsion technologies rather than focusing solely on battery-electric vehicles. Of the total investment pipeline, BEV manufacturing accounts for USD1.18 billion across 18 projects, creating annual production capacity exceeding 370,000 vehicles. In 2025, electrified vehicles represented more than 40 per cent of new vehicle registrations in Thailand, with HEVs accounting for 21.8 per cent and BEVs 19.6 per cent. Global manufacturers including Mercedes-Benz, BYD and Hyundai have also expanded local production, generating more than 16,000 jobs.
To strengthen domestic industry participation, the BOI has organised supplier matchmaking initiatives connecting Thai component manufacturers with international automakers, generating more than USD1.79 billion in local procurement opportunities. The latest investments are expected to deepen localisation across Thailand’s EV supply chain, enhance manufacturing competitiveness and reinforce the country’s role as a regional production and export hub for next-generation vehicles.
