Abstract

The device (200) has a switching unit for switching battery voltage. A current sensor (222) is connected to a heating apparatus, and senses current flowing through a positive temperature coefficient (PTC) heater part (214). A pulse width modulation (PWM) signal is authorized by the switching unit. A controller (224) is provided for calculating power consumption from perception current of the current sensor, and controls a PWM duty of the PWM signal according to the calculated power consumption. An independent claim is also included for a secondary electric heating method for a vehicle i.e. car.

Description

technical field [0001] The invention relates to an auxiliary electric heating device and an auxiliary electric heating method for automobiles. Background technique [0002] Typically, an electric car heater is used to heat the car's interior air, or in water-cooled engines to preheat cooling water or heat fuel. [0003] The electric heating device can be used as a PTC (Positive Thermister Coefficient: positive temperature coefficient) heater (Heater) and used as an auxiliary device for the heater unit of the car air conditioner, or it can also be composed of one or more electric heating devices to form a separate independent heating device. [0004] figure 1 It is a block diagram showing a conventional auxiliary electric heating device for automobiles. Such as figure 1 As shown, in the auxiliary electric heating device 10 of the automobile, the microprocessor 16 applies a control signal corresponding to the heating power of the PTC heater 17 preset on the power transisto...
