An electric car heating system is composed of heating elements and circuit. The heating elements are most important. The frequent heating elements include variable resistance heating element and constant resistance heating elements. In general the variable resistance heating elements are called as PTC. Generally the constant resistance heating elements are made of metal heating wires, metal films and carbon films and the heating plan is selected according to structure, process and cost of the battery system in specific design.
Depending on our experiences in electric heating R&D for more than 20 years and joint R&D of technical teams of research institutes in the car industry, battery heat management systems for battery pack structures of different cars and other products include heating film, silica gel films, epoxy resin plates, aluminum plates, PTC heater of car air-conditioner, nylon heating urea tubes, PTC heating water tubes and oil pipeline heating bars.
