High-efficiency components engineered for extreme environments.
As the automotive industry undergoes a seismic shift from internal combustion engines (ICE) to New Energy Vehicles (NEVs), the role of the Car Coolant Heater has evolved from an auxiliary luxury to a mission-critical component. In traditional vehicles, waste heat from the engine was used to warm the cabin. However, in electric vehicles (EVs), there is no "waste heat." This has led to the rapid global adoption of High-Voltage Coolant Heaters (HVCH) and PTC (Positive Temperature Coefficient) heaters.
Currently, the market is seeing massive demand from Northern Europe, North America, and Northeast Asia. Global OEMs are seeking thermal management systems that can not only provide cabin comfort but also ensure battery packs remain within the optimal temperature range (15°C to 35°C) to maintain range and longevity during freezing winters.
Staying ahead with AI-integrated and high-voltage technology.
With the rise of ultra-fast charging, heaters must now support 800V architectures, requiring superior insulation and semiconductor control.
Integration with vehicle software allows for real-time monitoring and predictive maintenance of the heating cycle, reducing downtime.
Modern heaters are dual-purpose, focusing equally on passenger comfort and the prevention of battery lithium plating during cold-weather charging.
