As the world pivots toward decarbonization, the automotive industry is undergoing a radical transformation. Traditional Internal Combustion Engines (ICE) relied on "waste heat" for cabin warming and engine temperature regulation. In the era of Electric Vehicles (EVs), this heat source no longer exists. This has birthed a multi-billion dollar market for High-Voltage Electric Coolant Heaters (ECH).
Today, the demand for ECH technology extends far beyond passenger cars. It is now a critical component in heavy-duty logistics, public transit buses, energy storage systems (ESS), and hydrogen fuel cell cooling cycles. Globally, manufacturers are racing to develop heaters that offer higher efficiency, lower weight, and seamless integration with complex vehicle thermal management systems (VTMS).
The industry is moving from 400V to 800V systems to facilitate ultra-fast charging. Our R&D focuses on high-voltage insulation and safety monitors to handle these increased loads.
Optimal battery performance requires specific temperature ranges. Our coolant heaters provide the necessary thermal energy to pre-condition batteries in cold climates, extending life and range.
Modern heaters are no longer simple "on/off" devices. They integrate with the vehicle's ECU via CAN or LIN bus for precise, energy-efficient pulse-width modulation (PWM) control.
The Hebei Province New Energy Vehicle Engineering Standard Laboratory has been built within our facility to support cutting-edge product R&D and performance testing, covering key tech areas with high barriers.
We launched China's first magnetic water pumps and three-way high-voltage insulation monitors, using advanced tech for precise monitoring and diagnosis. Boasting 20 years of experience in manufacturing electric vehicle parts, we have a strict quality management system with technology R&D and large-scale production advantages.
Our factory and R&D base span over 35,000 sqm. With full-automatic SMT lines and over ten assembly & testing lines, our annual output reaches 1.2 million electronic accelerator pedals, 300,000 magnetic water pumps, and 50,000 insulation monitors.
International buyers—from Tier 1 automotive suppliers in Germany to fleet managers in North America—demand reliability above all. Our export experience covers markets such as France, Canada, Russia, and the United States, where extreme cold weather makes electric coolant heaters indispensable.
Passed ISO/TS16949 by German Rhine in 2008 and continuously upgraded our system for reliability. We implement full-staff quality management, following TS16949 in all processes to meet the needs of multiple vehicle manufacturers.
"Emma handled the process very well and professionally. Great to work with her. The pumps are for a prototype and the manufacturer modified the PWM signalling as requested. The integration of the electric coolant heater was seamless."
