EVLINK High Voltage Coolant Heater Solutions
Welcome to EVLINK, where we are dedicated to providing efficient and safe high voltage coolant heater (HVCH) solutions for new energy vehicles. Our B-series and Q-series high voltage electric heaters have captured 70% of the Chinese thermal management heavy-duty truck market. The EVLINK high power 24kW heater has been in use since 2020, establishing our leadership in the high-power heater field.
Technical Introduction
EVLINK's high voltage coolant heaters utilize ceramic insulated PTC technology. This technology is flexible, suitable for various sizes and power applications, and offers efficient heat transfer and rapid response time. HVCH is suitable for power voltages ranging from 350 to 1000 volts, with power outputs from 8 to 35kW.
Market Position and Partnerships
In August 2023, EVLINK partnered with several well-known Chinese heavy-duty truck integrators to provide advanced 870V HVCH electric heater technology for their new electric vehicle models. This technology complements existing 600V coolant heaters, featuring enhanced electronic performance and reliable aluminum die-cast design, providing manufacturers with a dependable preheating heater in the new electrification field.
Product Features
EVLINK’s coolant heaters feature a compact modular design, reducing product size and weight. They provide consistent temperature distribution in battery packs and vehicle interiors, enhancing battery energy performance. EVLINK's high voltage PTC heaters are recognized by domestic OEMs for their outstanding efficiency and performance.

Application Scenarios
The development of new energy heavy-duty trucks is rapidly advancing. In transportation scenarios such as ports, mines, and short to medium-distance intercity routes, electric heavy-duty truck tractors are equipped with high power 24kW high voltage coolant heater PTCs. These heaters enable heating functions via a single button on the air conditioning panel. PTC power is controlled according to working conditions, achieving rapid temperature rise during driving, energy-saving temperature maintenance, meeting heating needs at -30°C. At -15°C, the cabin temperature can rise to 20°C within just 5 minutes, and defogging can be completed within 90 seconds, providing a convenient driving experience.
Product Advantages
- Enhanced Heating Effect: PTC heating systems significantly improve battery heating efficiency, allowing the battery to reach the set temperature more quickly.
- Efficient Heat Transfer: PTC heaters use gas or liquid as a heat transfer medium. Although there is some heat loss, their low thermal resistance and high heat exchange efficiency are notable.
- Stable Temperature Control: Due to the properties of PTC materials, resistance increases as temperature rises, allowing self-regulation and temperature limitation, ensuring stable and safe temperature control.
- Rapid Response: PTC heaters quickly respond to temperature changes, providing the required heat promptly, raising battery temperature in a short time.
Future Outlook
EVLINK will continue to focus on providing innovative and sustainable solutions for the automotive industry, creating better driving and riding experiences for customers.
