Munich-based automotive giant BMW has commenced the construction of its dedicated production facility for fifth-generation high-voltage batteries in Thailand. The new assembly plant, located in Rayong, is poised to play a pivotal role in the company’s foray into purely electric vehicles.
Scheduled to kick off in the latter half of 2025, the local production of battery electric vehicles (BEVs) marks a significant milestone for BMW Group Thailand. The decision to invest in battery production underscores BMW’s commitment to leveraging Thailand’s strategic position in the automotive market.
The forthcoming high-voltage battery assembly plant, spanning 4,000 square meters, signifies a substantial expansion of BMW Group Manufacturing Thailand’s operations. The facility will focus on assembling imported battery cells into modules, which will then be integrated into high-voltage batteries.
“This project represents a substantial investment by the BMW Group, exceeding 1.6 billion baht (approximately 42 million euros), with a significant portion, nearly 1.4 billion baht (around 36 million euros), dedicated to acquiring state-of-the-art equipment and systems,” stated a BMW representative.
BMW’s existing vehicle plant in Rayong already produces battery systems for plug-in hybrids, serving both the local and export markets. With the impending introduction of purely electric cars, BMW aims to expand its manufacturing capabilities in Thailand.
While BMW has not disclosed the specific model to be produced, it is confirmed that the fifth-generation high-voltage batteries will be utilized. This generation employs prismatic cells, painted and installed into modules by BMW, before being integrated into battery packs.
“The commencement of local high-voltage battery production in Rayong aligns with our strategic approach to electrifying our production network,” remarked Milan Nedeljković, BMW Board Member for Production, during the groundbreaking ceremony in Rayong. “This initiative not only fosters economic growth and job creation but also facilitates knowledge transfer in Thailand and the broader ASEAN region.”
