EV Investment in Thailand 2027: Companies, Projects & Opportunities in the Growing EV Market

Thailand is becoming an increasingly important destination for investment in electric vehicles, batteries, charging infrastructure and next-generation automotive technology.

For decades, Thailand has been one of Southeast Asia's major automotive manufacturing centres. The transition toward electric mobility is now reshaping that established industrial base, bringing new investments into battery electric vehicles, hybrid vehicles, batteries, EV components, charging networks, energy storage and smart mobility technologies.

As Thailand enters 2027, the country's EV investment story is no longer limited to vehicle assembly. Investment is spreading across the wider ecosystem required to manufacture, power, operate and maintain electric vehicles.

This creates opportunities for automotive manufacturers, battery companies, charging providers, component suppliers, technology businesses, investors and mobility startups.

According to Thailand's Board of Investment (BOI), cumulative approved investment across the country's EV ecosystem reached approximately 151.4 billion baht across 189 projects as of 31 August 2026. Battery cell and pack manufacturing represented approximately 87.1 billion baht of that total, followed by battery-electric vehicle assembly at about 38.6 billion baht and core components at approximately 12.6 billion baht.

The scale and diversity of these projects make Thailand an important market to watch for EV investment in 2027.

Thailand's EV investment ecosystem covers several interconnected areas:

• Battery electric vehicle manufacturing

• Hybrid and plug-in hybrid vehicle manufacturing

• Battery cell and pack production

• Energy storage systems

• Electric motors

• Battery management systems

• Power electronics

• EV charging infrastructure

• Battery swapping

• Automotive components

• Smart mobility technology

• EV software and connected vehicles

• Automotive research and development

Recent BOI figures demonstrate how broad this investment base has become.

As of May 2026, BOI reported 198 approved EV-related projects worth more than 137 billion baht. These included 18 BEV projects worth approximately 39.5 billion baht, 14 HEV/PHEV projects worth approximately 39.3 billion baht, 57 battery and energy-storage projects worth 33.5 billion baht, 49 key-component projects worth 12.5 billion baht and 42 charging/battery-swapping projects worth 9.8 billion baht.

The later August 2026 BOI figures show that approved investment had continued to grow.

Why Are Companies Investing in Thailand's EV Industry?

Several factors help explain the continuing investment activity.

1. Established Automotive Manufacturing Infrastructure

Thailand already has a large automotive manufacturing and supplier ecosystem.

This provides an existing industrial foundation for EV production.

Manufacturers can potentially access:

• Automotive suppliers

• Industrial estates

• Manufacturing expertise

• Logistics infrastructure

• Engineering talent

• Export infrastructure

• Automotive component manufacturers

The country's established automotive supply chain is therefore an important part of its EV transition.

2. Government Investment Promotion

Thailand's Board of Investment provides investment-promotion measures covering areas of the EV ecosystem.

These measures extend beyond vehicle assembly to areas such as batteries, important EV components and charging infrastructure.

The EV 3.5 package, for example, was designed to support investment across the EV ecosystem during the 2024–2027 period. BOI describes the package as covering manufacturing from vehicles to batteries, key parts and charging stations.

For businesses considering Thailand as a manufacturing or regional investment base, understanding the available incentives and eligibility requirements is therefore an important part of investment planning.

Major EV Companies Investing in Thailand

Thailand's EV ecosystem includes investments from companies headquartered in China, Japan, Europe and South Korea.

The BOI has reported that several manufacturers have already started BEV production in Thailand.

These include:

• Mercedes-Benz

• Great Wall Motor

• SAIC Motor-CP

• BYD

• AION

• Changan

• EV Primus

• BMW

• Hyundai Mobility

• OMODA & JAECOO

BOI reported that these manufacturers collectively employ more than 16,000 Thai workers.

This illustrates an important change in Thailand's automotive industry: EV investment is moving from announcements toward local manufacturing operations and supply-chain development.

BYD and the Expansion of EV Manufacturing

BYD is among the major Chinese EV manufacturers that have established production operations in Thailand.

Its presence is significant because vehicle manufacturing can create demand throughout the local supply chain.

Potential areas of opportunity include:

• Automotive components

• Battery-related products

• Electronics

• Charging systems

• Manufacturing equipment

• Logistics

• Engineering services

• Maintenance

• Software

As Thailand develops its EV manufacturing base, opportunities can extend beyond the vehicle manufacturers themselves.

Changan's EV Investment in Thailand

Changan Automobile has also invested in Thailand's EV manufacturing ecosystem.

The Thailand BOI announced an 8.8 billion baht investment plan for a factory producing electric and hybrid vehicles, with a first-phase annual capacity of 100,000 vehicles. The planned facility was designed to serve Thailand, ASEAN and export markets.

The project illustrates another important aspect of Thailand's EV strategy: using the country not only as a domestic sales market but also as a potential regional production and export base.

Hyundai Mobility's EV and Battery Investment

South Korean automaker Hyundai is another company expanding its local manufacturing presence.

Thailand's BOI approved approximately 1 billion baht in investment promotion for Hyundai Mobility Manufacturing to assemble BEVs and batteries locally starting in 2026.

The project is particularly relevant because it combines vehicle assembly with battery production.

This reflects the increasing importance of localising more of the EV value chain rather than importing complete vehicles and major components.

Battery Investment in Thailand

Battery manufacturing is one of the most important parts of Thailand's EV investment strategy.

According to BOI's August 2026 figures, battery cell and pack manufacturing accounted for approximately 87.1 billion baht of approved investment across the EV ecosystem, making batteries the largest investment category reported in that update.

Earlier BOI data from May 2026 recorded 33.5 billion baht across 57 battery and energy-storage projects.

Battery investment can create opportunities across multiple stages of the value chain.

These include:

• Battery cells

• Battery modules

• Battery packs

• Battery management systems

• Battery testing

• Thermal management

• Energy storage systems

• Battery recycling

• Battery materials

• Battery software

• Manufacturing equipment

The growth of battery manufacturing could therefore have implications well beyond the automotive industry.

EV Charging Infrastructure Investment

An expanding EV market requires an expanding charging network.

Thailand's BOI reported in May 2026 that approved investment in charging infrastructure and battery swapping reached approximately 9.8 billion baht across 42 projects, with more than 22,900 charging points planned, including more than 10,000 high-speed DC chargers.

This creates potential opportunities in:

• Public charging stations

• Highway charging

• Destination charging

• Fleet charging

• Workplace charging

• Apartment charging

• Charging management software

• Payment systems

• Energy management

• Charging hardware

• Maintenance services

The charging sector is therefore an important part of the broader EV investment story.

EV Components and Supply Chain Opportunities

Vehicle manufacturers require much more than batteries and vehicle bodies.

The expansion of EV production creates demand for advanced components and technologies.

BOI reported approximately 12.5 billion baht across 49 projects for important EV components as of May 2026. These included areas such as drive motors, battery management systems and power-control systems.

For Thai and international suppliers, potential areas include:

• Electric motors

• Inverters

• Battery management systems

• Power control units

• On-board chargers

• DC-DC converters

• Sensors

• Electronic control units

• Wiring systems

• Automotive electronics

• Lightweight components

This is particularly relevant for traditional automotive suppliers looking to transition into the EV supply chain.

Opportunities for Thai Automotive Suppliers

The EV transition is creating opportunities for existing Thai manufacturers to become suppliers to new EV manufacturers.

BOI reported that it has conducted 18 sourcing events, connecting more than 800 qualified Thai parts manufacturers with multinational automakers. According to BOI, these activities generated more than 1,200 business matches and could lead to approximately 60 billion baht in domestic procurement value.

This highlights a key opportunity:

Thailand's EV growth is not only about attracting foreign vehicle manufacturers. It is also about integrating local suppliers into the new EV value chain.

Companies that can provide advanced components, electronics, software, engineering and manufacturing capabilities may find opportunities as vehicle production expands.

Investment Opportunities Beyond EV Manufacturing

One of the most important developments in Thailand's EV ecosystem is the expansion into adjacent industries.

Energy Storage

• Power electronics

• Energy management software

Smart Mobility

Electric vehicles increasingly operate as connected digital platforms.

Investment opportunities can therefore extend into:

• Fleet management

• Connected vehicles

• Mobility platforms

• Intelligent transportation systems

• AI

• Data analytics

• Vehicle software

• Smart-city technology

EV Fleet Electrification

Commercial fleets are another potential area of growth.

Businesses operating:

• Delivery vehicles

• Taxis

• Corporate vehicles

• Last-mile transport

may increasingly require charging, fleet-management and energy solutions.

Thailand's EV Export Opportunity

Thailand's automotive industry has historically served both domestic and export markets.

The EV transition is creating an opportunity to build on that role.

Thailand's EV policy has included measures designed to encourage manufacturers to use the country as an export base. BOI previously reported adjustments to EV3 and EV3.5 requirements intended to make exports more useful in meeting manufacturers' production commitments.

For investors, this means the potential addressable market for a Thailand-based EV manufacturing operation can extend beyond Thailand itself.

A factory in Thailand can potentially serve customers across ASEAN and other export markets, depending on the company, product, trade arrangements and regulatory requirements.

Local Content Is Becoming More Important

Thailand is also encouraging greater use of locally manufactured components.

BOI's local-content promotion measure establishes minimum local-content requirements for certain promoted activities, including:

• BEV: 40%

• PHEV: 45%

• Electric buses and trucks: 40%

• EV equipment: 15%

The measure also includes a 50% corporate-income-tax reduction on qualifying net profits for two years after the corporate-income-tax exemption period ends, subject to the stated conditions.

This is important for investors because it increases the potential strategic value of local supplier relationships.

For companies entering Thailand, the question is therefore not simply:

“Where can we manufacture?”

It can also be:

“Which parts of our supply chain can be localised?”
