The demand for aftermarket PTC heaters is on the rise due to the increasing vehicle population and the rising cost of replacing original equipment (OE) PTC heaters. Aftermarket PTC heaters often offer a more cost-effective alternative to OE heaters, making them an attractive choice for many consumers.
The integration of PTC heaters with various vehicle systems, including climate control and battery management systems, is becoming more prevalent. This integration enhances the overall performance and efficiency of these systems. For example, some manufacturers are incorporating PTC heaters into the climate control system to deliver more precise temperature regulation.
Manufacturers are continually innovating PTC heater materials and technologies to enhance their performance and efficiency. These advancements are making PTC heaters more accessible and cost-effective for a broader range of vehicle manufacturers. For instance, some manufacturers are exploring innovative materials like graphene, known for their superior efficiency compared to traditional materials.
In regions with cold climates, PTC heaters are gaining popularity due to their ability to prevent ice and snow formation on windows, particularly the windshield. This not only enhances visibility but also contributes to road safety. PTC heaters can rapidly defrost windows, reducing the risk of accidents.
Luxury vehicles are increasingly incorporating advanced amenities, including PTC heaters, to enhance passenger comfort and convenience. PTC heaters find applications in providing heated seats, steering wheels, and windshields, significantly improving cabin comfort, especially during cold weather.
These systems require PTC heaters to function effectively in cold weather conditions. ADAS sensors need to be maintained at an optimal temperature to ensure proper operation, and PTC heaters help prevent sensor freezing and malfunction.
Heaters with positive temperature coefficients are self-regulating devices that operate in an open loop without any external diagnostics. PTC heaters, on the other hand, use conductive inks printed on thin, flexible polymer-based surfaces instead of wires and coils to create heat. As a result of the PTC heater’s material characteristics, it may function as its own sensor, removing the need for external feedback controls.
The risk of overheating in the product is avoided by using the PTC heater. It’s also more efficient and dependable than its standard model counterpart, making it ideal for products requiring safe, quick, and uniform heating.
As the threshold temperature rises PTC materials hinder current flow , but allow it to pass as it becomes colder. These heaters operate best between -40°C and 70°C, and manufacturers customize the threshold temperatures during the initial design phase.
In an EV, the PTC heater runs off the high voltage battery to maximize the power delivered to the heater. An IGBT or other high current power device is used to power on and off the heater, while the current and voltage sensors monitor the input voltage and current draw. To manage the heater and communicate with the other modules in the vehicle a high-tech MCU is used.
Conventional heater manufacturing includes processes such as acid bath which is not required in PTC heater manufacturing and hence minimizes the environmental effect. Multiple heater stages are possible.
