BYD officially opened its first electric vehicle (EV) manufacturing plant outside of China in Rayong, Thailand on July 4, 2024. This facility represents a significant investment of over 35 billion baht and has a production capacity of 150,000 vehicles per year. The Rayong plant will produce several BYD models, including the Dolphin, Atto 3, Seal, and Sealion 6. It also has the capability to manufacture key components such as batteries and power transmission systems. The factory covers an area of over 948,000 square meters and includes four production stages: forging, welding, painting, and assembly.
BYD’s investment in Thailand is part of a broader strategy to use the country as a manufacturing hub for exporting right-hand drive vehicles to various ASEAN countries. The plant’s opening aligns with Thailand’s goal to convert 30% of its annual vehicle production to EVs by 2030, supported by government subsidies and tax incentives aimed at promoting the EV industry.
