Electric High Voltage Coolant Heater (HVCH)
Revolutionary Heating Technology for EVs and Hybrids
The High Voltage Coolant Heater (HVCH) 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 HVCH maximizes contact area for rapid heat transfer, achieving:
- Ultrafast Warm-Up
- Precision Temperature Control
- 98%+ Energy Efficiency
Key Benefits:
- Extended Driving Range: Optimized battery usage ensures longer trips without compromising comfort.
- Compact Design: Minimal footprint for seamless integration into diverse vehicle architectures.
- Battery Conditioning: Maintains ideal battery temperature for performance and longevity.
- Scalable Solutions: Customizable control interfaces (CAN/PWM/Step Control) to meet OEM specifications.
Technical Highlights:
- Power Range: 5–30 kW (supports up to 800 VDC systems for commercial vehicles, LCVs, and heavy machinery).
- Certified Safety: IP67/IP6K9K ingress protection, E-Mark, and EMC compliance.
- Robust Reliability: 720-hour salt spray resistance, >500 hours dry-burn endurance.
Working Principle
The HVCH 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:
- Electric buses, coaches, and public transit
- Hybrid and battery-electric trucks
- Construction machinery and logistics vehicles
