EV3.5, BOI privileges, and the road to 12,000 chargers

Thailand's charging opportunity doesn't rest on market momentum alone. A coordinated policy framework is pushing in the same direction — supporting vehicle demand, setting infrastructure targets, and rewarding the investors who build the network.

Demand-side: EV3.5 and 30@30

The EV3.5 programme (2024–2027) continues Thailand's purchase support for battery-electric vehicles, with subsidies stepping down from ฿100,000 in 2024 to ฿75,000 in 2025 and ฿50,000 in 2026–2027 for qualifying models with batteries of 50 kWh or more, alongside an excise-tax reduction to 2% and import-duty relief during 2024–2025. Behind it sits the 30@30 policy: zero-emission vehicles to reach 30% of domestic vehicle production by 2030.

The framework has teeth on the production side too. From 2026, participating manufacturers must build two vehicles locally for every one imported under the scheme, rising to three-to-one in 2027 — anchoring the vehicle fleet, and its charging demand, in Thailand for the long term.

Supply-side: the 2030 network target

The national plan targets 12,000 DC fast chargers by 2030, with highway coverage at intervals of no more than 100 km on major routes. As of end-2024, Thailand had roughly 5,800 public DC charging points — meaning the DC network needs to roughly double in six years to hit the target. The build-out has years to run.

Investor-side: BOI privileges

EV charging projects are eligible for Board of Investment promotion. Under the current criteria, projects with at least 40 charging units — of which at least 25% are DC fast chargers — can qualify for A3-level privileges, including a five-year corporate income tax exemption and import-duty exemptions on chargers and essential components. Qualifying operators must implement smart energy-management systems and meet battery-handling and environmental requirements.

Charging sits within a wider EV investment wave: the BOI has tracked over ฿137 billion of EV supply-chain investment across vehicle, battery, and charging projects.

The through-line

Carbon neutrality by 2050 and net-zero by 2065 anchor the whole framework, sustaining long-term policy support for electric mobility. For landowners and investors, the signal is consistent: the infrastructure gap is real, the policy environment is aligned with closing it, and structured incentives exist for those who build. As always, incentive criteria and programme terms evolve — current conditions should be confirmed with the BOI at the time of application.
