Technical Introduction

EVLINK's high voltage coolant heaters utilize ceramic insulated and PTC heating layer innovative technology. EVLINK's special structure allows PTC elements to convert more effectively into heat, with a large contact area in the finned water tank for heating the coolant. Therefore, High Voltage Coolant Heaters achieve extremely fast heating times, high precision, and maximum efficiency. The 24kW heater is the same size as the 12kW heaters on the market.

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.

High Voltage Heater

EVLINK’s innovative technology includes ceramic insulation and PTC heating layers. EVLINK's special structure maximizes the conversion of PTC elements into heat, with a large contact area in the finned water tank for heating coolant. Therefore, High Voltage Coolant Heaters achieve extremely fast heating times, high precision, and maximum efficiency. This heater's special structure allows the 24kW heater to be the same size as the 12kW heaters on the market.

The B-series is the only heater on the market that utilizes minimal space to match independent thermal management units above 350 degrees, suitable for many buses, trucks, LCVs, and heavy-duty trucks. The electric auxiliary high voltage heater heats coolant when the temperature becomes too low and is integrated into the cooling circuit.
