The invention relates to a positive-temperature-coefficient thermistor electric heating system of an electromobile. The positive-temperature-coefficient thermistor electric heating system comprises a compressor, a first temperature-sensing bag, a front evaporator, a first draught fan, a first heater, a front electromagnetic door, a rear electromagnetic door, a rear expansion valve, a rear evaporator, a second temperature-sensing bag, a second heater, a second draught fan, a stored-liquid drying and filtering device and a condenser. The first draught fan and the second draught fan are correspondingly distributed at the front evaporator and the rear evaporator respectively. The first heater is distributed between the front evaporator and the first draught fan. The second heater is distributed between the rear evaporator and the second draught fan. By means of the positive-temperature-coefficient thermistor electric heating system, the defect that the heating reaction speed of a traditional refrigerant heat pump working mode is low is overcome, quick heating is achieved, and the heating effect is good; meanwhile combination of a positive-temperature-coefficient thermistor heating technology and a refrigerant heat pump heat supply technology is achieved, and the heating performance of the electromobile is greatly improved.
