Car manufacturers benefiting from the Thai government’s electric vehicle (EV) promotion measures will be required to invest in the domestic production of key EV components by 2026, according to the Bangkok Post. The three essential components—electric motors, reducers, and inverters—must be assembled locally. These parts are critical to an EV’s function, with electric motors converting electrical energy into kinetic energy, reducers acting like gearboxes, and inverters converting battery DC power into AC for the motor.
Mr. Ekniti highlighted that since the introduction of the government’s EV promotion initiatives—Phase 3.0 and 3.5—auto manufacturers have begun establishing production bases in Thailand, leading to a total investment of over 80 billion baht. The measures stipulate that participating companies must manufacture EVs domestically to match 100% of their first-year sales. If the local manufacturing requirement is not met in the second year, companies must produce 1.5 times the sales volume.
