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

Product Description

Designed specifically to supply thermal energy to the liquid-cooled heating circuits of electric vehicles. By heating the circulating coolant, it provides a controllable heat source for compatible battery thermal management systems, cabin heating units, and other vehicle thermal management applications.

The required heating capacity depends on the thermal load, target coolant temperature, ambient conditions, and system heat losses. Coolant circulation characteristics and heat exchanger performance also influence the actual amount of heat delivered to the target components.

To ensure an optimal application fit, the heater’s rated parameters should be determined by comprehensively considering the vehicle’s thermal requirements, power supply characteristics, and operating conditions.

Applications

24v Vehicle Coolant Heater Ptc Heating Solutions

Battery Thermal Conditioning

The high-voltage coolant heater provides supplemental heat to liquid-cooled battery systems when additional thermal input is required. Its integration helps support battery temperature management, with heating requirements determined by battery specifications, ambient conditions and the vehicle's thermal control logic.

Electric Vehicle Interior Heating

In coolant-based HVAC systems, the heater supplies thermal energy to the circulating fluid, which transfers heat to the cabin through an air-side heat exchanger. System performance depends on the heating capacity, coolant circulation and HVAC configuration.

Electrified Commercial Vehicle Applications

The heater can be integrated into compatible thermal management systems for electric buses, commercial trucks and construction vehicles. Engineers should evaluate vehicle voltage, thermal demand, coolant compatibility and installation requirements before selecting a suitable configuration.

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.
