Product Description

This high-voltage PTC water heater is developed for electric vehicles requiring an electrically powered coolant heating solution. It transfers heat to the coolant, which circulates through designated thermal circuits to provide battery temperature conditioning or cabin heating.

Designed for integration into vehicle-level electrical and thermal systems, the heater requires careful matching of supply voltage, heating capacity, coolant flow and installation conditions. These factors determine whether the selected configuration meets the application’s operating requirements.

Electrical connections, communication protocols, control signals and protection settings should be verified during system design to support reliable integration with the vehicle controller.

Applications

High Voltage PTC Water Heater 15-35kW 400-1100V for Electric Vehicles, EV Battery Thermal Management Systems and Heating IP67

Battery Preheating Applications

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.

Passenger Compartment Heating

The heated coolant circulates through a dedicated HVAC heat exchanger, delivering heat to the vehicle interior. The resulting cabin temperature depends on the heater output, circulation performance, airflow and overall HVAC system configuration.

Electric Bus and Truck Platforms

For electric buses, heavy-duty trucks and construction machinery, the heater can be integrated into vehicle coolant circuits designed for higher thermal loads. Selection requires verification of operating voltage, required heating capacity, installation conditions and system-level safety requirements.

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.
