Product Description

Designed for electric vehicle thermal management systems, this high-voltage PTC coolant heater provides controlled heat output for circulating coolant. The heated coolant can be directed to the battery cooling circuit, cabin heating system or other compatible thermal applications, depending on the vehicle architecture.

Heating efficiency and temperature response are influenced by the selected power rating, coolant circulation, operating temperature and heat-transfer conditions. Evaluating these parameters together helps ensure compatibility with the vehicle’s thermal requirements.

The heater can be integrated into the vehicle control system through the specified communication and enable interfaces, supporting coordinated operation with other thermal management components.

Applications

PTC Heater HVCH 25KW30KW35KW 600V800V1100V 12KG Bus Truck Construction Machinery BTMS RBS Battery Heating Cabin Heating EVLINK

EV Battery Thermal Management

The high-voltage PTC coolant heater raises coolant temperature to support battery thermal management in cold environments. Its application depends on the battery pack's operating temperature range, heating requirements, coolant circulation and vehicle control logic.

Electric Vehicle Cabin Heating

By heating the circulating coolant, the system supplies thermal energy to the cabin HVAC heat exchanger. This enables cabin heating in electric vehicles, with actual performance determined by coolant temperature, flow rate and heat exchanger efficiency.

Electric Buses, Trucks and Construction Vehicles

Designed for electric buses, trucks and construction vehicles with demanding thermal requirements, the heater provides configurable heating-power options. Vehicle integration should consider DC bus voltage, thermal load, mounting space and coolant circuit compatibility.

Frequently Asked Questions

1.What does a high voltage PTC coolant heater do?

It uses electrical power from the vehicle’s high-voltage system to heat circulating coolant. The coolant can then transfer heat to the battery system, cabin heat exchanger or another approved thermal circuit.

2.Is the 15–35kW heater suitable for every electric vehicle?

No. It is intended for projects with relatively high heating demand. The correct configuration depends on operating voltage, required heat output, coolant conditions, installation space and control requirements.

3.Can one heater support both battery and cabin heating?

It may support either application when the vehicle coolant architecture and control strategy allow it. Some vehicles use separate circuits, while others use valves or a shared thermal loop.

4.What information is required to select a heater?

Please provide the vehicle type, operating-voltage range, required heating power, coolant type, expected flow rate, inlet-temperature range, installation space, connector requirements and CAN communication requirements.

5.Can the mounting, connectors or control interface be customized?

Project-specific requirements can be evaluated after the installation drawing, packaging space and electrical interface are provided. The final configuration should be confirmed in the approved drawing and technical agreement.
