Thick-Film Heater: The "Efficient Temperature Control Core" Empowering New Energy Vehicles
In the upgrade of new energy vehicles (NEVs) toward "longer range, higher safety, and intelligence," the temperature control system’s performance directly impacts overall user experience. Pain points like low-temperature battery capacity loss, high heating energy consumption, and layout challenges in confined spaces have long restricted industry development. However, thick-film heaters—designed specifically for NEVs—solve these issues with four core advantages: high efficiency & energy saving, space-friendliness, safety & stability, and precise temperature control, offering a revolutionary solution for NEV temperature control upgrades.
1. High Efficiency & Energy Saving: 98% Thermal Efficiency + Rapid Heating
Low-temperature "range anxiety" in NEVs often stems from traditional heaters’low efficiency (e.g., ~85% for PTC heaters) and slow heating, which consume battery power and cut range by over 30%. Thick-film heaters address this fundamentally:
With 98% thermal efficiency (only 2% energy loss), they reduce heating energy consumption by 15%-20% vs. traditional PTC heaters at -20℃, saving 5-8 kWh per 100 km and extending range by 50-80 km.
Heating speed reaches ≥150℃/s: coolant hits above 40℃within 30 seconds of startup, and temperature rises from -20℃ to 20℃ in 5 minutes. This quickly preheats batteries to their optimal 25-40℃range, reducing low-temperature capacity loss and extending battery cycle life by over 20%.
2. Space-Friendly: Ultra-Thin & Lightweight Design
NEV chassis/cabin space is precious (for batteries, motors, etc.), but traditional heaters are bulky (5-10mm thick, ≥500g). Thick-film heaters excel here:
Planar structure (2-5mm thick, 50% thinner than traditional models) and lightweight (200-300g, 40%-60% lighter) enable flexible installation in narrow spaces (battery pack layers, motor shells, cabin ducts).
"Invisible installation" frees up cabin/storage space for compact NEVs. Lightweight design also contributes to vehicle weight reduction—every 10kg cut boosts range by 2-3 km.
3. Safety & Stability: High-Temperature Sintering + Multiple Protections
NEVs face harsh conditions (-40℃to 60℃, vibration, corrosion). Thick-film heaters ensure reliability:
Core heating layer uses high-temperature sintering (≥850℃), bonding resistor paste and ceramic substrate for strong vibration resistance (stable after 100,000+ vibration tests).
Ceramic substrate + heat-resistant insulation layer resist coolants/electrolytes, with insulation resistance ≥100MΩand breakdown voltage ≥2000V (no leakage). Over-temperature protection (auto-power-off at 80-100℃) prevents fires.
Stable operation from -40℃ to 120℃, with a failure rate <0.1% (far below traditional heaters’1%).
4. Precise Temperature Control: Uniform Heating + Zone Regulation
Traditional "one-size-fits-all" heating fails to meet NEVs’refined needs (battery ，cabin zone heating). Thick-film heaters excel:
Planar structure ensures ±5℃uniform heating, avoiding local overheating (e.g., battery thermal runaway risks).
Modular design enables zone control: adjust heating power for different battery areas or cabin zones (front/rear seats) to enhance comfort.
Real-time linkage with BMS/ECU via CAN bus: auto-adjusts power (e.g., reduce power when battery heats up, preheat during charging), improving temperature control energy efficiency by 15%-25%.
Conclusion
Amid NEV industry growth, thick-film heaters align with NEV tech upgrades via their four core advantages. As solid-state batteries and 800V platforms popularize, they will iterate toward "higher power density (≥500W/cm²) and smarter integration (chip integration)." Set to become a standard NEV temperature control component, they will drive NEVs toward better range, safety, and intelligence, fueling high-quality industry development.
