1. Q: What are the advantages of thick film electric heaters compared with traditional PTC heaters?
A: Thick film heaters have higher energy efficiency (up to 95% or more), faster heating speed (second response), smaller size, and high power density, which are suitable for the strict requirements of new energy vehicles on space and energy consumption.

2. Q: What new energy vehicle scenarios are suitable for the 7-15kW power range?
A: 7-10kW is mostly used for passenger car battery/cabin heating, 10-15kW is suitable for commercial vehicles or extremely cold regions, and can meet the needs of large-capacity battery packs for rapid preheating and in-car heating.

3. Q: How is the safety of thick film heaters guaranteed?
A: It uses insulating ceramic substrates and high-temperature resistant thick film materials, has overcurrent, overtemperature, and short-circuit protection functions, and has no open flames, meeting the automotive grade IP67 protection and flame retardant standards.

4. Q: Why are thick film heaters more suitable for high voltage platforms (such as 800V)?
A: Thick film technology can adapt to high voltage by adjusting the resistor paste formula, has strong pressure resistance, and its efficiency is not affected by voltage increase, while traditional PTC is prone to efficiency reduction under high voltage.
