In 2025, sales of electric cars are expected to surpass 20 million, accounting for over a quarter of cars sold worldwide. In the first three months of 2025, global electric car sales were up 35% year-on-year. Batteries are the core of EVs, and BTMS are essential for maintaining their optimal performance, lifespan, and safety. Efficient battery thermal management helps prevent thermal runaway, enhances energy density utilization, and reduces degradation over time.

Governments worldwide are introducing stringent regulations to improve battery safety, prevent accidents, and extend battery life, especially in electric vehicles (EV’s). These regulations emphasize the need for battery thermal management system as an essential subsystem. For instance, the European Union Battery Regulation 2023/1542, adopted on July 12, 2023, and in force since August 17, 2023, aims to make batteries more sustainable throughout their lifecycle. Compliance with evolving thermal safety regulations is compelling OEMs to integrate advanced BTMS solutions with real-time thermal monitoring, predictive analytics, and AI-enhanced diagnostics, boosting the market growth.

Continuous R&D is driving the development of innovative BTMS technologies that are smarter, lighter, and more energy-efficient. New materials such as phase change materials (PCM), heat pipes, and nanofluids are being introduced to enhance thermal conductivity. Companies like Gentherm, Dana Limited, and Valeo among others are integrating AI-enabled predictive control in BTMS for dynamic temperature regulation. As BTMS evolves technologically, it becomes increasingly adaptable, scalable, and attractive to the automotive industry, expanding the market growth during the forecast period.
