When temperatures drop, battery performance drops with them. Charging slows, internal resistance rises, and capacity declines—leading to reduced range, unstable output, and accelerated aging. For electric vehicles, energy storage systems, forklifts, and industrial equipment operating in cold climates, battery heating is no longer optional—it is essential.
Our PTC Heating Film is engineered as a high-efficiency, self-regulating thermal solution that keeps lithium battery systems operating at optimal temperature, even in environments as low as -40°C. Designed for seamless integration into battery packs, it delivers safe, stable, and energy-efficient heating—ensuring your systems perform when it matters most.
Smart Self-Regulating Heating Technology
Unlike traditional heating elements, PTC (Positive Temperature Coefficient) technology automatically adjusts power output based on temperature. At low temperatures, the system delivers higher power for rapid heating. As the temperature approaches the target range, resistance increases, reducing current and stabilizing heat output.
This intelligent control eliminates the risk of overheating and removes the need for complex external temperature regulation systems.
Engineered for Safety and Reliability
PTC Heating Film for Battery Low-Temperature Heater
PTC heating film is a self-regulating battery heating solution designed for low-temperature environments. As a professional manufacturer and OEM supplier, we provide ultra-thin, flexible heating films for lithium battery packs, ensuring stable performance from -40°C to 80°C. Ideal for EV, ESS, forklifts, and industrial battery systems, our factory-direct solutions offer high safety, energy efficiency, and long service life.
Safety is critical in battery systems. Our PTC heating film is designed with:
- Self-limiting temperature control (no overheating risk)
- No open flame or electric arc during operation
- Parallel circuit structure for continued operation even if partial damage occurs
- Stable and uniform heat distribution across battery cells
This ensures a safer alternative to conventional resistance heating solutions, especially in high-demand industrial and EV applications.
Ultra-Thin, Flexible, and Easy to Integrate
With a thickness as low as 0.22mm, the heating film can be directly attached to battery modules or packs without affecting structural design. Its flexible polyimide (PI) structure allows easy installation across various battery configurations.
Whether for retrofitting existing systems or integrating into new designs, it provides a lightweight and space-efficient solution.
High Efficiency, Lower Energy Consumption
Our PTC heating film offers thermal conversion efficiency above 70%, ensuring fast heating with optimized energy use. Once the target temperature is reached, power consumption automatically decreases—helping reduce overall system energy load.
This makes it an ideal solution for energy-sensitive applications such as EVs and energy storage systems.
Designed for Real-World Applications
This heating solution is widely used across industries where battery performance in cold environments is critical:
- Electric Vehicles (EV) and e-mobility systems
- Energy Storage Systems (ESS)
- Forklift and industrial lithium batteries
- Golf carts and utility vehicles
