High Voltage Thick Film Coolant Heater For EV Car
Products Description
PTC thick film heaters for new energy vehicles are a new generation of high-efficiency electric heating elements that combine the positive temperature coefficient characteristics of PTC with thick film printing technology. Compared with traditional PTC ceramic heaters, they have significant advantages in response speed, thermal efficiency, and high-pressure adaptability, making them a core upgrade solution for the thermal management system of new energy vehicles.

Products Details
Core applications of new energy vehicles
Cabin heating
Both air-cooled and water-cooled heating systems provide rapid heating, enhancing driving and passenger comfort in winter.
Defrosting and defogging
Rapidly heats the glass to ensure driving safety.
Battery thermal management
Rapidly preheating the battery to the optimal range of 15-25℃ at low temperatures improves charging efficiency and battery life, and reduces low-temperature degradation.
800V High Voltage Platform
Adapted to high-voltage architecture, it has become the mainstream choice for thermal management of the next generation of electric vehicles.

FAQ
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 to solve the problem of start-up delay in a low-temperature environment?
A: A thick film heater directly heats the coolant/air and can output heat in 3-5 seconds. It cooperates with the battery management system (BMS) preheating strategy to eliminate the bottleneck of low-temperature cold start.
4. Q: Can zone temperature control be achieved?
A: Multiple heating circuits can be designed to independently control different areas (such as battery packs, front and rear areas of the cabin), but it needs to match the thermal management pipeline or air duct design of the whole vehicle.
5. Q: What is the future direction of technology development?
A: Focus on higher power density (＞20kW/L), wide temperature range compatibility (-40℃~150℃), and coordinated optimization with heat pump systems to further reduce energy consumption.
