Heating Film Series Solutions

Heating films solutions for new energy batteries are among the key technologies for enhancing the performance of new energy vehicles in low-temperature environments. Performance degradation of EV batteries under low temperatures can be effectively mitigated by some measures such as selecting appropriate heating film types, optimizing heating methods and strategies, designing reasonable system structures, and incorporating intelligent control measures, thereby improving the reliability and usability of new energy vehicles. 

Heating Solutions:

  • PI Heating FilmsThin, lightweight and flexible: Occupy minimal space with excellent flexibility and slim profile.Efficient & Uniform Heating: Deliver rapid and uniform heat distribution through surface-based heatingReliable in Harsh Environments: Perform steadily in vacuum conditions and in environments exposed to oil, acids, solvents, and alkaline substances.
  • Silicone Heating FilmsFlexible & Malleable: Ensure complete surface contact with heated objects through excellent pliability and compressibility.Fast & Even Heat-Up: Provides quick heating with consistent temperature distribution and high efficiency.Physically Superior: Provide strong resistance to vibration, compression, and abrasion, with high electrical insulation strength.Easily Customizable: Support customization for multiple forms including 3D shapes, PSA adhesive, and pre-cut holes for easy installation.
  • Epoxy Board Heating FilmsThin & Lightweight: Feature a thin, lightweight, and wear-resistant structure with a smooth, flat surface.Tight Contact: Ensure close contact with the heated object to enable efficient heat transfer.Strong Bonding : Deliver higher bond strength than conventional rigid insulation boards, without delamination or blistering during long-term use.Mechanically Robust: Offers excellent mechanical strength, high electrical insulation, and resistance to moisture and flame.
  • PTC Heating FilmsSelf-Limiting: Leverage the PTC effect to enable rapid heating at low temperatures while automatically reducing power as temperature rises.Radiation-Efficient: Uses carbon-based conductive materials to provide high infrared emissivity and electrothermal conversion efficiency, allowing most heat to be emitted as infrared radiation.Highly Safe: Significantly improves operational safety by maintaining a consistently low surface temperature.

Solution Optimization:

By installing heating films on the surface of battery packs or battery modules, the series of solutions for new energy battery heating films convert electrical energy into thermal energy via the electrothermal conversion principle. This rapidly raises the battery temperature, ensuring that the battery maintains a normal operating state even in low-temperature environments.

  • Battery Self-Heating Method:Working Principle: The method relies on heat generated during battery charging and discharging to warm the battery itself.Limitations: It features slow heating performance and has been gradually phased out by mainstream automakers.
  • Blower Heating Technology:Working Principle: The internal temperature of the battery pack is regulated by blowing hot air through the external air conditioning system.Limitations: It features relatively slow heating performance and involves additional risk of local overheating due to improper design.
  • Internal Battery Pack Heating – PTC Heating ElementsBenefits: These PTC heating elements provide safe operation, high thermal conversion efficiency, rapid heating, flameless operation and self-regulating temperature control.Limitations: They feature relatively larger form factor, which may require additional space within the battery system.
  • Heating Film TechnologyBenefits: These heating films can provide excellent heating performance with rapid response and a flexible design that conforms to the shape of the battery pack for efficient heat transfer.Limitations: They may cause uneven temperature distribution within the battery system
