1. Application requirements: For new energy vehicle power batteries & energy storage stations, especially the currently mainstream lithium batteries (ternary lithium batteries and lithium iron phosphate batteries), their impedance increases several times at low ambient temperatures, making charging and discharging very inefficient. Low-temperature operation also significantly affects the battery module's lifespan, electricity efficiency, and safety. Therefore, battery modules need to be heated.
2. Traditional heating solutions: Conventional external heating solutions usually use constant power heating films with point-type temperature control. All these heating methods have issues like uneven temperature, and point-type controls can't manage the temperature across the whole heating surface. There’s also the risk of overheating and burning if there’s a heat dissipation problem, and the heating speed is slow.
PPTC heating films perfectly match these application requirements, addressing the shortcomings of traditional heating films, and can provide a safer, more efficient, and more stable heating solution for battery modules.
Self-limiting temperature safety feature: Made with polymer PTC material, it automatically adjusts power when it reaches a certain temperature to prevent overheating, ensuring safe and efficient heating.
Flexible, lightweight, and easy to stick: Soft and thin, it can bend and be cut any way you like, fitting closely to all kinds of complex surfaces and adapting to various situations.
Wide applications across many fields: Thanks to its safety features and flexibility, it's widely used in cars, healthcare, smart homes, and more.
Automatic adjustment to prevent overheating: When the temperature rises, the resistance automatically increases, and the power decreases accordingly, effectively eliminating the risk of overheating and dry burning.
No need for temperature control, constant temperature operation: Once the set temperature is reached, it automatically maintains a basic constant temperature, and can work safely without any extra thermostat setup.
Damage-resistant and no hotspots: Even if there are minor damages or slight overlaps during installation, it’s unlikely to create hotspots, making it much safer than regular heating films.
Soft and lightweight texture: flexible like paper, can bend and cut at any angle
Adapts to complex surfaces: perfectly fits curved surfaces, irregular parts, pipes, and battery pack surfaces
Easy and efficient to install: Comes with strong adhesive, just peel and stick to fix in place
Safe and reliable: flame-retardant, aging-resistant materials with a long service life. No open flames or red heat, not easy to burn out when overloaded. Excellent insulation performance, suitable for sensitive scenarios like medical or battery use.
