Thailand's battery electric vehicle (BEV) market showed a marked decline in February, with monthly sales of just 6,168 units — down about 18.6% year-on-year, and by a larger margin month-on-month. Industry data also show overall electric-vehicle registrations across all EV types fell 22.1% year-on-year to 5,744 units in February. The downturn is widely attributed to the Thai government's gradual scaling back of EV purchase subsidies.
Thailand's earlier "EV 3.0" subsidy scheme paid buyers of qualifying vehicles: those with battery capacity of at least 50 kWh received 100,000 baht in 2024, falling to 75,000 baht in 2025; vehicles under 50 kWh received 50,000 baht in 2024, falling to 35,000 baht in 2025 and further to 25,000 baht in 2026-2027. To ease pressure on manufacturers' registration timelines, the government extended the EV3.0 registration deadline from December 2025 to January 2026, and the EV3.5 deadline from December 2027 to January 2028 — though this has not fully offset the near-term hit to sales from the subsidy step-down.
Because Chinese EV brands dominate Thailand's battery-EV market, the sales decline has hit Chinese automakers that rely heavily on exports to Thailand particularly hard. In January, the market briefly hit a record as manufacturers rushed to sell ahead of the subsidy reduction, with Chinese brands capturing nearly 47% share — BYD standing out in particular — but the market cooled sharply in February, suggesting the earlier "rush to buy" pulled some demand forward, leaving a wider-than-expected gap once the subsidy stepped down.
Analysts say Thailand's EV subsidy reduction reflects an attempt to balance fiscal sustainability with nurturing the domestic industry — early high subsidies quickly grew the market but strained the budget, prompting a shift toward more modest support alongside buffers like extended registration deadlines for manufacturers. For Chinese automakers, the temporary softening of Thai demand is prompting some to reassess their production footprint and export strategy in the country; whether they can absorb capacity pressure by deepening local production or expanding into other ASEAN markets will be a key indicator to watch for China's EV push into Thailand.
The sales slowdown is also feeding directly into domestic production capacity. BYD and GWM have already built Rayong-based factories with combined annual capacity exceeding 550,000 vehicles, with GWM completing its EV3.5 local-production requirements to offset import quotas as of late July. With domestic demand now softening, these manufacturers face the immediate question of whether that installed capacity can be smoothly absorbed, or whether they will need to pivot toward exports to other ASEAN markets or adjust production schedules — making Thailand's short-term EV market swings not just a sales-figure issue, but a variable that bears directly on the pacing of the entire Chinese EV supply chain's localization in the country.
