Product Description
The Battery Thermal Management System (BTMS) for electric vehicles serves as the "central nervous system" that ensures the efficient and safe operation of power batteries. In extreme conditions—such as intense cold or sweltering heat—the BTMS utilizes liquid cooling, direct cooling, or PTC/heat pump circuits to precisely maintain the battery's operating temperature within an optimal range. This not only effectively enhances vehicle range and fast-charging efficiency but also fundamentally mitigates the risk of thermal runaway caused by overheating, making it a core technology for extending battery lifespan and ensuring overall vehicle safety.

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.
