Air Cooling Segment is Largest Due to Cost Efficiency and Scalability

The air-cooling segment is the largest in the BTMS market, owing to its cost-effective and scalable solutions suitable for a wide range of applications, particularly in compact electric vehicles and smaller battery systems. Air cooling uses fans and ventilation systems to regulate battery temperature, offering a simpler and more economical approach compared to liquid or refrigerant-based systems.

In the air-cooling segment, passive air cooling, which leverages natural airflow without additional energy input, holds the largest market share. This sub-segment is widely used in low-power applications and smaller EV models where energy efficiency and affordability are prioritized. With the increasing demand for cost-efficient and reliable solutions in the electric two-wheeler and three-wheeler markets, passive air-cooling systems are expected to maintain their dominance in this segment.

Liquid Cooling Segment is Fastest Growing Due to High Efficiency and Performance

The liquid cooling segment is emerging as the fastest-growing segment within the BTMS market, driven by the demand for higher efficiency and superior temperature regulation capabilities. Liquid cooling systems, which circulate coolant to absorb and dissipate heat from battery cells, are becoming increasingly popular in high-performance EVs and energy storage systems requiring precise temperature control.

Among the liquid cooling systems, the direct liquid cooling sub-segment is seeing the most rapid growth due to its effectiveness in maintaining uniform temperatures across battery modules. This technology is particularly favored in premium electric vehicles and commercial EVs, where managing thermal loads efficiently is critical to performance. The expanding market for high-performance electric vehicles and heavy-duty transportation solutions is expected to further boost the adoption of direct liquid cooling systems.

Passenger Car Segment is Largest Due to High Electric Vehicle Sales

The passenger car segment holds the largest share in the BTMS market, primarily attributed to the surging sales of electric passenger vehicles globally. As automotive manufacturers increasingly focus on electrification strategies, battery thermal management has become an integral part of vehicle design, ensuring both safety and reliability.

Within this segment, compact and mid-sized electric cars are the largest sub-segment, reflecting the growing consumer preference for affordable and eco-friendly vehicles. The introduction of government incentives, coupled with advancements in battery technology, is enhancing the adoption of electric passenger cars, thereby driving the demand for efficient thermal management solutions tailored to these vehicle categories.

Lithium-Ion Battery Segment is Largest Due to Widespread Use in EVs

Lithium-ion batteries dominate the BTMS market as they are the most widely used energy storage technology in electric vehicles. Known for their high energy density and long cycle life, lithium-ion batteries require effective thermal management solutions to prevent overheating and degradation during operation.

The largest sub-segment within lithium-ion batteries is the NMC (Nickel Manganese Cobalt) chemistry, which offers a balanced performance in terms of energy density, safety, and cost. The increasing use of NMC batteries in electric cars and hybrid vehicles is driving demand for advanced BTMS solutions that can maintain optimal temperatures and improve battery longevity. With continuous R&D efforts aimed at enhancing battery efficiency and safety, the NMC sub-segment is expected to retain its leading position in the market.

Asia-Pacific Region is Fastest Growing Owing to Expanding Electric Vehicle Market

The Asia-Pacific region is the fastest-growing market for BTMS, fueled by the rapid expansion of the electric vehicle sector in countries like China, Japan, and South Korea. China, in particular, is the largest market for electric vehicles, with significant government support for EV adoption and infrastructure development. As a result, the demand for advanced battery thermal management solutions has surged, making Asia-Pacific a crucial market for BTMS providers.

Among the countries in this region, India is expected to show the highest growth rate during the forecast period. The Indian government’s initiatives to promote electric mobility, combined with the increasing focus of local manufacturers on developing affordable electric two-wheelers and compact cars, is propelling the demand for BTMS solutions. The development of new battery manufacturing facilities and the growth of the electric vehicle ecosystem are also contributing to the region's rapid expansion.
