Product Description

Modern electric vehicles require coordinated thermal management across multiple subsystems. This 15–35 kW high-voltage PTC coolant heater is designed to serve as an electrically powered heat source within compatible liquid-cooling architectures.

With a 400–1100 V DC operating range, the heater can be evaluated for vehicle platforms with different high-voltage requirements. Its CAN communication and enable-signal interface provide connection options for integration with vehicle-level control systems.

Rather than operating as an isolated heating component, the heater should be selected as part of the complete thermal system. Electrical supply characteristics, coolant circulation, heat-exchanger capacity and supervisory control logic all influence the final system configuration.

Applications

High Voltage Battery Heater for Electric Bus and EV Battery Thermal Management | Advanced PTC Heating Solution

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.
