PTC air heaters can be used in the following automotive applications:
Cabin Heating: Used in EVs and hybrid vehicles to replace traditional engine-based heating.
Defrosting & Demisting: Installed in windshields and rearview mirrors to prevent fog and ice buildup.
Battery Thermal Management: Maintains optimal battery temperature for better efficiency in cold weather.
Seat & Steering Wheel Heating: Provides localized heating for driver and passenger comfort.
HVAC System Integration: Works within air ducts and climate control units to regulate airflow heating.
Voltage Compatibility: Choose based on the vehicle type:
12V / 24V → For defrosting, seat heating, and low-power heating applications.
48V / 60V / 72V / 96V → Used in hybrid vehicles and mild-hybrid systems.
300V – 400V → High-voltage EV and hybrid vehicle HVAC heating.
Power Output: Choose between 200W – 3,000W, depending on the heating requirement.
Size & Mounting: Ensure compatibility with HVAC air ducts, battery packs, or vehicle structure.
1.Installation Steps:
Choose Mounting Location:
For cabin heating, install within the HVAC air duct system.
For defrosting, place near the windshield vents.
For battery heating, integrate into the battery thermal management system.
2.Secure the Heater:
Use mounting brackets or clips to fix the heater in place.
Connect the Electrical Wiring:
Connect the heater to the vehicle's power supply (DC or AC voltage).
Ensure correct polarity and grounding.
3.Integrate with HVAC & Controls:
Connect to the vehicle's climate control system for automatic temperature regulation.
Use PWM (Pulse Width Modulation) or CAN Bus control for smart operation.
Automatic Temperature Regulation: The PTC heater self-regulates and prevents overheating.
Manual & Smart Control:
Can be manually activated via the dashboard controls.
HVAC systems can automatically adjust the heater power output based on temperature sensors.
Energy-Efficient Heating:
In EVs and hybrids, the PTC heater works efficiently with low power consumption.
Check for Dust & Blockages: Ensure air vents are not blocked for optimal airflow.
Inspect Electrical Connections: Prevent loose wires or corrosion for stable operation.
Monitor Performance: Look for unusual heating delays or airflow reduction.
Waterproof Protection: If used in outdoor defrosting applications, ensure IP54 – IP67 rating for durability.
To effectively use a PTC air heater in the automotive industry, ensure proper installation, electrical connection, and HVAC system integration. Its self-regulating heating, safety, and energy efficiency make it ideal for EVs, hybrid cars, and fuel-powered vehicles in cabin heating, defrosting, and battery thermal management applications.
