The market is projected to grow from USD 4.67 billion in 2026 to USD 19.98 billion by 2034, exhibiting a CAGR of 19.90% during the forecast period. Asia Pacific dominated the automotive battery thermal management system market with a market share of 45.93% in 2025.
Fortune Business Insights™ has deep-dived into these insights in its latest research report, titled “Automotive Battery Thermal Management System Market, 2026-2034.”
The analysis shows that original equipment manufacturers (OEMs) and top companies are investing more in thermal management innovations because of the rising demand for plug-in EVs and hybrid vehicles. For example, Valeo developed smart thermal management solutions for EV batteries that help maintain better battery life and increase the battery range by up to 30% across seasons. This trend indicates a strong demand for automotive battery thermal management systems worldwide.
Major Players Profiled in the Market Report:
Segments
Dual Transmission Benefits and Rising EV Demand to Propel HEV and BEV Segment Growth
Based on propulsion type, the market is divided into battery electric vehicles (BEV), plug-in hybrid electric vehicles (PHEV), and hybrid electric vehicles (HEV). The HEV segment holds a major share globally as it offers dual transmission (electric and conventional fuel-based driving range), especially in regions where charging infrastructure is insufficient. Meanwhile, the BEV segment is set to lead the market—accounting for a 57.36% share in 2026—owing to the adoption of advanced vehicle technologies, rising demand for electric passenger and commercial vehicles, and strict emission standards globally.
High Heat Conductivity and Simplicity to Drive Liquid and Air Cooling & Heating Segments
By technology, the market is categorized into air cooling & heating, liquid cooling & heating, and phase change material (PCM). The air cooling & heating segment holds a prominent share due to its simple, easy design that is widely adopted by economically priced EVs. However, the liquid cooling & heating segment is expected to lead throughout the forecast period (accounting for a 51.36% market share in 2026) as liquid coolants perform more effectively due to their higher heat conductivity and heat capacity compared to air.
