Product Description

Series B is a dedicated product extended from Series A, custom-engineered for battery-swapping heavy-duty trucks. It adopts a compact plastic housing with minimal footprint and delivers a maximum heating power of 24 kW. Despite its compact form factor, it provides robust heating capacity to satisfy rapid heating requirements for multiple battery packs under ultra-low temperature conditions. Two variants are offered: a flying lead version and a 4-pin connector version compatible with CATL battery thermal management systems, enabling seamless integration with a wide range of vehicle and battery systems.

Applications

High Voltage PTC Coolant Heater 20KW 22KW 24KW HVCH 400V 600V 800V for Electric Bus, Truck, Construction Machinery and BTMS

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.
