Thick film printed heating element used in automobile industry, which is mainly used in the current new trend new energy automobile. Because electric vehicles must use an active heating system, but the waste heat generated by the battery system is not enough to meet the comfort requirements of the cab. In addition, the battery management system needs to effectively control the temperature when the battery pack is started, operated and charged, which is particularly necessary for the use of electric vehicles in colder climates.
The thick film technology can provide heating accuracy, repeatability, design flexibility and power handling capabilities, and meet space constraints, very suitable for this application. The heater is a very simple circuit with a controlled resistance that can output the required temperature under a given power input. Depending on the selected material, the thick film heater can be self-limiting, or it can be designed to have a high or low temperature coefficient of resistance according to the requirements of the control system. Thick film heaters can be built on multiple types of substrates, compatible with operating temperatures from below zero to 700°C, with almost no power requirements.
Now the thick film printed heating elements are more popularly used in the developed countries in automobile industry.
