KResearch expects that the demand for sensors, which are essential components for the automotive manufacturing in Thailand, will steadily increase. Due to stricter environmental measures to curb carbon emissions, automakers have placed higher attention on environmental and safety systems in their new car models. Also, many car companies have increasingly used sensors in the production of electric vehicles (EVs). As a result, the volume of sensors used in vehicles has increased from 45 units per car on average 10 years ago to 60 units per car at the moment. The demand for sensors for car manufacturing is set to rise further in the future.
The year 2019 will mark a turning point in propelling the sensor demand. In the past, sensors are generally used for the production of petrol-fueled cars, but in the future, sensors will be increasingly required in the manufacturing of EVs. This is because several carmakers in Thailand are speeding up the investment and the launch of EVs, especially hybrid electric vehicles (HEV) and plug-in hybrid vehicles (PHEV), some of which have already begun investing in car assembly facilities since 2018. The investment in the battery electric vehicles (BEVs) in Thailand may take a while before it actually happens because it depends on the availability of charging stations. However, the BEV investment should happen no later than 2021because car makers will have to produce the vehicles within three years after they receive an approval from the Board of Investment.
KResearch projects that in the next five years, the demand for sensors in the production of electric vehicles in Thailand will increase by an average of 58 percent per year in line with the manufacturing of HEV / PHEV vehicles, which are expected to be a catalyst for growth of the domestic EV market and exports. Hence, in 2023, the demand for sensors for the production of HEVs will rise to 23 million units, followed by 6 million units for PHEVs and 900,000 units for BEVs.
