Thailand has secured more than $4.1 billion in investment pledges across its electric vehicle supply chain, spanning 198 projects covering battery electric vehicles, hybrid systems, battery manufacturing, critical components, and charging infrastructure.
In a statement on Monday, the Thailand Board of Investment (BOI) said the investment featured contributions from manufacturers from China, South Korea, Germany, and Japan. The investment is distributed across the full supply chain.
BEVs account for $1.18 billion across 18 projects, establishing annual domestic production capacity of over 370,000 units, with Chinese manufacturers BYD, SAIC Motor, Aion, Changan Auto, and Omoda and Jaecoo, along with South Korea’s Hyundai Mobility and Germany’s Mercedes-Benz.
Hybrid vehicles account for a combined $1.18 billion across 14 projects, capitalising on Japanese automakers’ legacy hybrid technologies.
Batteries and energy storage systems attracted $1.00 billion across 57 projects, securing localised battery cell and pack manufacturing.
Critical components such as drive motors, battery management systems, and power control units drew $373 million across 49 projects.
Charging infrastructure received $292 million across 42 projects, funding over 22,900 charging stations nationwide, including more than 10,000 high-speed DC fast chargers.
In 2025, electric vehicles accounted for over 40 percent of all new vehicle registrations in Thailand, with HEVs leading at 21.8 percent and BEVs at 19.6 percent.
Mercedes-Benz pioneered local luxury BEV production in Thailand starting in 2022, followed by a wave of Chinese manufacturers including BYD, Great Wall Motor, SAIC Motor, and Aion in 2024. Changan Auto and EV Primus launched manufacturing operations in 2025, while South Korea’s Hyundai Mobility and China’s Omoda and Jaecoo began production rollouts in 2026. These manufacturing investments have created more than 16,000 local jobs.
The BOI has also facilitated 18 Sourcing Day events, pairing more than 800 Thai parts manufacturers with multinational automakers and resulting in over 1,200 business matches. These connections can generate over $1.79 billion in domestic procurement value and transition traditional tier-1 and tier-2 suppliers into the high-tech EV supply chain, the BOI noted.
Narit Therdsteerasukdi, Secretary General of the Thailand Board of Investment, said Thailand’s strategy of supporting all propulsion technologies, including hybrid, plug-in hybrid, and battery electric, allows legacy players and new entrants to invest and grow together.
