From Cold Starts to Warm Rides: Advanced Thick-Film Heaters on Steel (HoS) for EV Batteries

Electric vehicle battery heating is becoming increasingly critical as the market expands, particularly in colder climates where maintaining optimal battery temperatures is essential for performance and longevity. Effective thermal management not only ensures passenger comfort but also enhances charging efficiency, driving range, and battery lifespan. To meet these demands, heating systems in EVs must be compact, lightweight, energy-efficient, and durable, capable of operating reliably under challenging environmental conditions. Thick-film heaters on steel (HoS) are emerging as a promising technology in this space, especially gaining traction in Asian markets. These heaters offer significant advantages over traditional solutions like heat pumps, cartridge heaters, and PTC ceramic heaters. HoS technology delivers higher power density, greater design flexibility, and faster thermal response, all while reducing size and weight. Their robustness in harsh environments also makes them well-suited for the rigorous demands of electric mobility. The article highlights a case study illustrating the practical benefits of HoS heaters in EV battery applications, showcasing how this technology supports the broader industry goal of advancing electric mobility. By improving thermal management, HoS heaters contribute to more efficient and reliable EV operation, potentially accelerating adoption in colder regions. As the EV market evolves, innovations like HoS are poised to play a crucial role in overcoming the challenges of battery heating and thermal control.
