Oaxis Unveils AdaptiveHeatshield: A Smart Thermochromic Film That Regulates EV Battery Temperature Without Power
Consumer electronics company Oaxis has launched AdaptiveHeatshield, a passive thermochromic coating that dynamically adjusts solar reflectivity based on ambient temperature, reducing EV battery thermal management energy draw by up to 31%.
Oaxis Unveils AdaptiveHeatshield: A Smart Thermochromic Film That Regulates EV Battery Temperature Without Power
Oaxis, the consumer electronics brand best known for its ink-free printing technology, has launched AdaptiveHeatshield — a passive thermochromic film designed specifically for electric vehicle battery enclosures. The film requires no electrical power to operate and dynamically adjusts its solar reflectivity in response to ambient temperature, reducing battery thermal management energy consumption by up to 31% in simulated highway conditions.
The Science
AdaptiveHeatshield uses a proprietary microencapsulated phase-change material (mPCM) embedded within a polymeric film matrix. Below 25°C, the film remains semi-transparent, allowing solar radiation to contribute to battery warmth in cold climates. Above 35°C, the mPCM droplets undergo a reversible endothermic transition, causing the film to shift to a highly reflective state — reflecting up to 78% of incident solar irradiance.
The transition is entirely passive and reversible, with no degradation observed across 5,000 thermal cycles in Oaxis's accelerated aging tests.
Installation and Compatibility
The film is applied as a self-adhesive laminate directly to the exterior of EV battery enclosures during manufacturing or as an aftermarket retrofit. It is available in three thicknesses — 0.3mm, 0.5mm, and 0.8mm — to accommodate different form factors and thermal load requirements. Oaxis has secured compatibility partnerships with CATL, BYD, and Panasonic Energy for OEM integration.
Market and Pricing
Oaxis is initially selling AdaptiveHeatshield through its own channel and authorized distributors at $249 per vehicle for the standard 0.5mm variant. The company claims the energy savings translate to approximately 3-5% improvement in total vehicle range under hot climate conditions, paying back the cost within 18-24 months for average drivers.
Pre-orders opened November 10th, with shipping to North America and Europe scheduled for February 2028.
