Power Battery Heating Film is a flexible electric heating element designed for low-temperature thermal management of power batteries. It is typically composed of an insulating substrate, a resistive heating layer, conductive leads, an adhesive layer, and a protective layer, and can be attached to or integrated with battery cells, modules, and packs. When energized, the film converts electrical energy into heat through resistive heating, enabling rapid battery warm-up and improved temperature uniformity under low-temperature conditions. This helps enhance charging and discharging performance, reduce internal resistance, and shorten cold-start time. Key performance indicators include power density, heating rate, temperature uniformity, dielectric strength, aging resistance, flexibility, and dimensional stability. The product must also maintain safety and reliability under vibration, high-humidity and high-temperature conditions, thermal cycling, and prolonged electrical operation.

The upstream supply chain for Power Battery Heating Film mainly includes insulating materials such as polyimide film, silicone rubber, and polyester film; heating materials such as copper foil, nickel-chromium alloy, and resistive paste; as well as adhesives, wires, connectors, temperature sensors, and insulating protective materials. Midstream manufacturers are responsible for circuit design, etching or printing, lamination, die cutting, lead connection, and performance testing, and generally provide customized products based on battery structure, operating voltage, and thermal-management requirements. The downstream market mainly consists of battery cell and module manufacturers, battery-pack integrators, thermal-management system suppliers, and end-equipment manufacturers. Final applications include new energy vehicles, construction machinery, aerospace equipment, power tools, rail transit, and other power systems.
