Key Players
Competitive Landscape
Chiller makers compete with firms that sell full cooling systems. Electric vehicle firms also bring liquid-cooling skills. Some companies make parts that move heat from coolant into refrigerant. Others sell wider battery cooling or full vehicle cooling systems. Vehicle makers compare these roles before they choose a supplier for each platform.
During 2026 suppliers added more combined cooling hardware as fast charging raised heat and space limits. MAHLE started e-compressor output in India in August 2026. Hanon Systems expanded its global thermal aftermarket team in September 2026. Vehicle makers now compare local plant support and system design. They also review service over the life of the vehicle. A supplier with several linked parts can cut separate sourcing work. The same supplier must pass more system tests before production starts.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| September 2026: Hanon Systems expanded its global aftermarket organization for thermal management. | More electrified vehicles need replacement thermal parts and local service. | Original equipment thermal suppliers are building replacement channels as EV fleets age. | Service parts can add revenue after a vehicle platform launches. |
| August 2026: MAHLE began e-compressor production in India with annual capacity above 300,000 units at full output. | Local EV production needs nearby thermal hardware with automotive quality controls. | Thermal suppliers are placing high-voltage part production closer to growth markets. | Local compressor supply can support integrated cooling modules and shorter supply routes. |
| June 2026: Schaeffler presented electrical and thermal energy management systems for next-generation vehicles. | Higher charging and electrical loads need joint control of battery and vehicle heat. | Thermal functions are moving into wider vehicle energy-control systems. | System suppliers can package controls and thermal hardware for platform nominations. |
DENSO, Eberspächer and Modine also work in vehicle cooling and heating. Dana TM4 and Eaton add commercial electric vehicle systems and electric powertrains. Their direct chiller depth differs. Each company can still support part of the wider battery cooling system.

These firms work in several parts of electric vehicle cooling. Some make refrigerant cooling parts. Some make combined modules. Others serve commercial vehicles or liquid cooling. Direct chiller makers and wider cooling firms can compete on the same vehicle program.
Who leads the electric vehicle battery chillers market?
Sanhua Automotive and DENSO show direct chiller work. Valeo and Hanon Systems also show direct refrigerant cooling work. MAHLE and Modine cover wider battery cooling systems and modules. The first four firms sit closer to direct chiller hardware. MAHLE and Modine compete through a wider set of cooling parts on each vehicle platform.
Which companies have documented qualification or quality approvals?
DENSO, Valeo and MAHLE document vehicle programs with quality checks. Hanon Systems and Schaeffler also show work on approved vehicle thermal systems. Each new vehicle platform still needs its own final approval. Strong past work does not remove the need for fresh tests on a new chiller program.
Which companies provide battery cooling or integrated thermal products?
Sanhua Automotive and DENSO show battery cooling products. Valeo also shows direct cooling work. MAHLE and Hanon Systems show wider cooling systems. Modine also works in battery cooling. Eberspächer adds heat for vehicle cabins. Eaton adds liquid cooling for hot hardware. Much of this work helps move heat away from the pack. The group covers direct chillers, wider battery cooling and support parts for electric vehicles.
Which companies serve Europe and North America?
Valeo, MAHLE, Hanon Systems and Modine document work in Europe and North America. Dana TM4 and Eaton also work in both regions. Schaeffler and Eberspächer add their own regional work. Product depth changes by vehicle program. Local plants and engineering teams can help during approval. Each vehicle maker still sets its own technical tests.

Research Methodology
These firms show the market structure and do not form a full ranking. Analysis include a firm only when public evidence links it to battery cooling or related thermal hardware. Sources include official announcements, patents, regulator records and public filings. Each claim stays tied to the named cooling product or platform. FMI keeps market-share estimates as its own views for the forecast period. This method keeps public company evidence separate from FMI market estimates.
