Thailand has secured over $4.1bn in investment pledges across its electric vehicle (EV) supply chain, according to the Thailand Board of Investment (BOI).

The investments span 198 projects. Of the total, $1.18bn has been pledged across 18 battery EV (BEV) projects, $1.18bn across 14 hybrid projects, $1bn across 57 battery and energy storage system (ESS) projects, $373mn across 49 critical components projects, and $292mn across 42 charging infrastructure projects.

The investment surge is driven by the growing interest from global automakers to establish regional hubs in southeast Asia and shift production towards clean energy, BOI said on 3 July. Thailand produced around 1.455mn vehicles in 2025 and remains southeast Asia's largest automotive manufacturing hub.

Thailand has implemented incentives to promote EV production in recent years, including tax measures and provisions. Its policy framework notably extends beyond pure EVs, unlike its regional competitors, according to the BOI.

Thailand intends to expand the role of its local suppliers in the global automotive value chain by supporting all EV technologies, said secretary general of the BOI and secretary of the National EV Policy Board Narit Therdsteerasukdi, at the International Electric Vehicle Technology Conference in Bangkok last week.

Thailand's policy framework has already prompted several Japanese and Chinese manufacturers such as Mazda, Changan Automobile and BYD to set up EV plants in Thailand, while German automaker Mercedes-Benz launched BEV production in the country in 2022, according to the BOI.

Electrified vehicles made up over 40pc of all new vehicle registrations in Thailand in 2025, led by hybrids with 21.8pc and BEVs with 19.6pc, according to the BOI.

Thailand is aiming for EVs to reach 30pc of its total automotive production by 2030.

BEV and plug-in hybrid passenger EV (PHEV) production more than doubled on the year to 71,000 units and 17,300 units, respectively, in 2025, while hybrid passenger EV output rose by 12pc to over 214,000 units during the same period, according to the Federation of Thai Industries.
