Final specifications and protection thresholds should be confirmed according to the selected configuration and approved technical agreement.

Product Description

The heater converts high-voltage electrical energy into thermal energy, heating the circulating coolant for battery thermal management, cabin heating, and other compatible vehicle systems.

Overall heating performance depends on rated power, coolant type and flow rate, inlet temperature, pressure drop, and heat exchanger efficiency. Selecting the right heater requires considering the vehicle’s operating conditions and thermal management requirements to ensure proper system integration.

Applications

A Series 6–18kW High Voltage PTC Coolant Heater 400–800V for Electric Vehicle Thermal Management

EV Battery Thermal Management

The heater can warm coolant before it enters the battery thermal management circuit. This supports battery temperature control during low-temperature operation. Battery temperature limits, required heating rate, coolant flow and control strategy should be defined by the vehicle manufacturer.

Electric Vehicle Cabin Heating

For cabin heating, warmed coolant passes through a cabin heat exchanger to provide heat for the passenger compartment. Heating performance depends on both coolant circulation and airflow through the HVAC heat exchanger.

Electric Buses, Trucks and Construction Vehicles

The 15–35kW range is intended for vehicle platforms with substantial heating demand. Suitability for a specific vehicle must be confirmed from its voltage platform, target heat output, available installation space and coolant-system design.

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.
