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 A-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 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.

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.

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.

EVLINK’s PTC heaters are completely innovative products. Unlike trading companies, EVLINK has a very strong pre-sales technical team, professional and modern assembly lines, and production processes. We have after-sales personnel in various countries. Our main target markets include electric commercial vehicles, large battery thermal management, and HVAC cooling systems.
