Thailand is positioning itself as a key player in Southeast Asia’s battery and electric vehicle (EV) industries. Yet the path forward is complex, with opportunities tied closely to the challenges of supply chain resilience, green credentials, and global competition.

Dr Pimpa Limthongkul, President of the Thailand Energy Storage Technology Association, says the country’s next steps will determine whether it can capture long-term value from the global transition to new energy.

“The most pressing issue related to battery and EV in Thailand is balancing the rapid EV uptake with healthy local manufacturing,” Dr Limthongkul explains in an email interview with e27.

Imported vehicles have accelerated adoption, but long-term success, she argues, requires a domestic supply chain that is not only robust but also sustainable. That means securing reliable sources of raw materials, building capacity for recycling, and ensuring safety in handling end-of-life products.

Equally important, Dr Limthongkul stresses, is the need to make EVs genuinely green. “How do we make the battery and EV truly low carbon?” she asks.

While shifting from combustion engines reduces tailpipe emissions, Thailand must also tackle the carbon footprint of battery production and electricity generation. With fossil fuels still a mainstay of the national grid, greening the electricity supply is vital to realising the climate benefits of mass EV adoption.

Opportunities for local industry and innovation

Thailand has already made significant progress with incentive packages such as EV3.0 in 2022 and EV3.5 in 2024, which introduced subsidies and tax exemptions to make EV ownership more appealing. These schemes also linked incentives to local production, catalysing investment in domestic battery and component manufacturing.

“We need to lock in and promote local manufacturing, and at the same time secure volume for export of both EV and batteries produced in Thailand,” Dr Limthongkul says.

She also highlights the role of regulation in shaping a competitive yet safe industry. “Improving and ensuring safety by putting in proper regulations and standards will be critical,” she notes.

Beyond manufacturing, Dr Limthongkul emphasises that Thailand must also accelerate its transition to renewable energy: “We need to increase the percentage of green electricity in the grid at a faster pace.” Alongside this, energy storage systems can serve as a backbone for renewable integration, supporting both grid resilience and the growth of the EV ecosystem.

Human capital development is another pillar. The Ministry of Higher Education, Science, Research and Innovation is expanding training programmes to reskill and upskill the workforce in battery technologies. Multi-year R&D initiatives are underway to improve recycling and materials recovery, reducing reliance on imports while fostering a circular economy.

Threats on the horizon

Still, Dr Limthongkul is candid about the risks. “Oversupply and price wars are potential threats,” she warns.

Excess inventory can lead to aggressive pricing that undermines supplier profitability while discouraging consumers from buying immediately, expecting even lower prices ahead.

Cost competitiveness is another concern. “High production costs for local manufacturing, especially compared with mass-produced units from China, are a real challenge,” Dr Limthongkul observes. The lack of reliable after-sales services—from limited parts availability to long repair times—also risks undermining consumer trust.

Macroeconomic conditions and political instability only add to the uncertainty. “An overall economic slowdown can lead to hesitation in new EV purchases and investment from foreign and local players,” Dr Limthongkul says. Global and local unrest, she adds, can slow the pace of critical investments, including those needed for green grid transformation.

Despite these risks, Pimpa is optimistic about the role of innovation in creating a safer, greener industry. “I am looking forward to battery technologies that lead to higher safety and sustainability—those innovations that can bring us closer to the net zero goal,” she says.

For transportation, she points to next-generation chemistries that deliver high energy density and affordability. She sees promise for the grid in low-cost, safe energy storage systems that enable large-scale renewable integration.

Equally important, Pimpa notes, are technologies that extend batteries’ lifespans: “What has been invested in producing the batteries should be utilised most effectively.” She cites better sensing, predictive tools, and modular designs that make batteries easier to disassemble, repair, and repurpose.

Recycling is another frontier. “We need technologies that make battery recycling more efficient and green, from identification through digital battery passports to low-carbon recycling processes,” Dr Limthongkul says. Advances in fault detection, fire protection and storage safety also form part of this innovation landscape.

Milestones achieved

Since the launch of the EV30@30 initiative in 2021, which set the target that 30 per cent of vehicles produced in Thailand would be zero-emission by 2030, the country has achieved remarkable progress. EV registrations are on track to exceed 20 per cent of passenger car sales by 2025, reflecting both growing consumer appetite and the success of incentive programmes.

Global manufacturers have responded by committing to building battery plants in Thailand, reinforcing the country’s reputation as an emerging hub. The education and R&D ecosystem is also advancing, with initiatives focused on recycling and materials recovery to reduce import dependence.

Meanwhile, the Ministry of Industry is working on a comprehensive battery recycling framework that could close the loop in Thailand’s battery lifecycle.

Looking ahead to 2026

Dr Limthongkul predicts that by 2026, Thailand will see EV prices becoming competitive with internal combustion vehicles, driving broader adoption. Industrial sectors will increasingly turn to battery-powered mobility, while the commercial and industrial energy storage market will expand on the back of cheap solar power and falling storage costs. Local supply chains will deepen, not just in manufacturing but also in after-sales and repair services.

“By then, we will see more focus on end-of-life battery management and safety,” Dr Limthongkul says.

She believes this will ensure that the industry matures in a way that balances rapid growth with sustainability.
