Product Description:
Designed specifically for outdoor electric battery thermal management, our Self-Controlled Temperature Flame Retardant Flexible Graphene Heating Film Infrared PTC integrates advanced graphene technology, PTC positive temperature coefficient effect, flame retardant protection and flexible design into one, solving the core pain points of outdoor battery low-temperature performance attenuation, poor safety and difficult installation. It is a high-efficiency, safe and reliable thermal management solution for outdoor electric batteries, providing stable temperature support for the normal operation of batteries in harsh outdoor environments.
As the core of the product, the graphene heating layer has excellent thermal conductivity (up to 5300 W·m−1·K−1, far higher than traditional heating materials) and electric heating conversion efficiency (up to 99%), which can quickly convert electrical energy into heat energy and realize uniform surface heating without local hotspots. Combined with the PTC positive temperature coefficient effect, the product has an intelligent self-controlled temperature function—when the temperature rises to the preset critical value, the resistance of the PTC material will increase sharply, the power will drop rapidly to maintain a constant temperature; when the temperature drops, the resistance will decrease, and the power will increase to speed up heating, without the need for additional temperature control devices or manual intervention, fundamentally avoiding overheating damage to the battery and ensuring energy-saving operation.
Targeting the harsh outdoor environment, the product is equipped with a professional flame-retardant structure, adopting Class A flame-retardant materials that meet international safety standards, which can effectively prevent combustion and inhibit the spread of fire, even in extreme conditions such as short circuits, it will not cause fire hazards, providing multiple safety guarantees for outdoor electric batteries. At the same time, the product adopts a flexible substrate (such as polyimide), which is thin (usually 20-200 μm), lightweight and highly flexible, can be arbitrarily bent, folded and attached to the surface of battery modules of various shapes, fitting closely without affecting the original structure of the battery, and is easy to install in the narrow space of outdoor battery packs.
The product emits far-infrared rays with a wavelength of 8-15 μm during the heating process, which is consistent with the wavelength of human body radiation and has good thermal penetration. While heating the battery, it can also promote the uniform conduction of heat inside the battery, avoid local temperature differences, reduce the internal resistance of the battery, and effectively improve the charging efficiency, discharge capacity and service life of the outdoor battery—especially in low-temperature environments (-30℃ to 0℃), it can quickly preheat the battery to 10-15℃, solve the problem of lithium plating during low-temperature charging, and significantly improve the low-temperature performance of the battery.
In terms of durability and environmental adaptability, the product has excellent performance: it can operate stably in a wide temperature range of -269℃ to 400℃, with strong resistance to cold, high temperature, acid and alkali, and can adapt to various harsh outdoor environments such as rain, snow, strong cold and strong sunlight. The surface adopts a high-density waterproof and anti-corrosion coating, which has IPX7-level waterproof performance, effectively preventing moisture, dust and corrosive substances from entering the interior, ensuring long-term stable operation of the heating film under outdoor conditions. The service life of the product can reach more than 200,000 hours, with low attenuation and low maintenance cost, which can reduce the long-term operation cost of outdoor battery equipment.
This product is widely applicable to various outdoor electric battery scenarios, including outdoor energy storage batteries, electric vehicle batteries (outdoor parking), solar energy storage battery packs, outdoor communication base station batteries, outdoor detection equipment batteries, etc. It can be customized according to the size, power and temperature requirements of different battery products, supporting 12V-48V low-voltage power supply, which is safe and energy-saving, and perfectly matches the power supply system of outdoor electric batteries.
Compared with traditional battery heating solutions (such as resistance wire heating, liquid cooling heating), our product has obvious advantages: self-controlled temperature without additional control devices, flame-retardant safety, flexible installation, uniform heating, energy saving and environmental protection, and strong adaptability to outdoor environments. It not only solves the problem of low-temperature performance degradation of outdoor electric batteries, but also effectively prolongs the service life of batteries, reduces safety risks, and provides a reliable thermal management guarantee for the popularization and application of outdoor electric equipment.

Applications:
In practical application scenarios, this graphene heating film plays an irreplaceable role in ensuring the stable operation of outdoor electric batteries in various complex environments. For outdoor energy storage batteries used in remote areas, fields and construction sites, the product can resist extreme cold and hot weather, ensure that the battery maintains a stable working temperature even in minus 30℃ snowstorms or 40℃ high-temperature exposure, avoid power failure caused by temperature impact, and ensure the continuous supply of electricity for equipment such as construction machinery, field detection instruments and emergency lighting.
For electric vehicle batteries parked outdoors for a long time, especially in cold northern regions, the heating film can quickly preheat the battery in winter mornings, solving the problem of difficult startup, slow charging and reduced driving range caused by low temperature, and improving the driving experience and battery service life. For solar energy storage battery packs installed on rooftops, open fields and other outdoor locations, it can adapt to the alternating changes of day and night temperature and harsh weather such as rain and snow, prevent the battery from being damaged by moisture and low temperature, and ensure the efficient storage and conversion of solar energy.
In outdoor communication base station batteries, which are often located in remote mountainous areas, deserts and other harsh environments, the product’s flame-retardant, waterproof and corrosion-resistant properties can effectively prevent safety hazards caused by short circuits, moisture and other factors, and the self-controlled temperature function can avoid overheating or overcooling of the battery, ensuring the stable operation of the communication base station and uninterrupted signal transmission. For outdoor detection equipment batteries (such as environmental monitoring, geological exploration, border patrol equipment), the thin and flexible design of the heating film can be perfectly attached to the small-size battery module, without increasing the volume and weight of the equipment, while providing stable temperature support, ensuring that the detection equipment can work normally in extreme environments.
In addition, the product’s customizable feature makes it suitable for various types and specifications of outdoor electric batteries, whether it is a large-scale energy storage battery pack or a small outdoor detection equipment battery, it can be tailored according to the actual size, power and temperature requirements, matching the power supply system of different equipment. Its low-voltage power supply design (12V-48V) is consistent with the power supply standard of most outdoor electric batteries, which can be directly connected to the battery system for use, without additional power conversion equipment, simplifying the installation process and reducing the overall configuration cost.
