Revolutionary Heating Technology for EVs and Hybrids
The High Voltage Coolant Heater (HVH) by New NanFeng Group delivers unmatched efficiency in converting DC electrical energy into thermal energy with near-zero losses. Featuring an ultra-thin heating layer fused to the heat exchanger, the HVH maximizes contact area for rapid heat transfer, achieving:
1.Ultrafast Warm-Up
2.Precision Temperature Control
3.98%+ Energy Efficiency
Key Benefits:
1.Extended Driving Range: Optimized battery usage ensures longer trips without compromising comfort.
2.Compact Design: Minimal footprint for seamless integration into diverse vehicle architectures.
3.Battery Conditioning: Maintains ideal battery temperature for performance and longevity.
4.Scalable Solutions: Customizable control interfaces (CAN/PWM/Step Control) to meet OEM specifications.
Technical Highlights:
1.Power Range: 5-30 kW (supports up to 800 VDC systems for commercial vehicles, LCVs, and heavy machinery).
2.Certified Safety: IP67/IP6K9K ingress protection, E-Mark, and EMC compliance.
3.Robust Reliability: 720-hour salt spray resistance, >500 hours dry-burn endurance.
Working Principle
The HVH utilizes high-pressure PTC elements paired with advanced IGBT/PWM controllers to enable stepwise or continuous power modulation. Heat is transferred via a circulating coolant medium (50% water + 50% ethylene glycol), ensuring uniform thermal distribution across vehicle systems.
Applications
Ideal for:
1.Electric buses, coaches, and public transit
2.Hybrid and battery-electric trucks
3.Construction machinery and logistics vehicles
