1. A car seat heater, comprising:
a heating wire which is coupled to a car seat and which comprises a metal-plated carbon fiber;
a seat temperature sensor configured to detect a temperature of the heating wire; and
a variable temperature controller configured to control the temperature of the heating wire according to a diameter of the metal-plated carbon fiber and a thickness of a plated metal thereof, wherein:
the diameter of the metal-plated carbon fiber of the heating wire is equal to or more than 1 μm and less than 10 μm,
the thickness of the plated metal of the metal-plated carbon fiber of the heating wire is equal to or greater than 0.3 μm and less than 1 μm, and
when the diameter of the metal-plated carbon fiber of the heating wire is equal to or greater than 1 μm and less than 3 μm, and the thickness of the plated metal of the metal-plated carbon fiber of the heating wire is equal to or greater than 0.3 μm and less than 0.6 μm, a temperature control sensitivity of the variable temperature controller is adjusted such that the heating wire is heated to 60 degrees for a temperature rise time to be equal to or greater than 210 seconds and less than 245 seconds.
