The invention relates to a charging port temperature detection method and system, a vehicle and a storage medium. A voltage check point is arranged on a live line and/or a zero line of a vehicle end; the method comprises the following steps: acquiring the real-time voltage of a voltage check point and the real-time charging current of a charging loop in the charging process; the real-time resistance of a charging connection point is determined, and the charging connection point comprises a live line connection point of the charging gun and the charging port and/or a zero line connection point of the charging gun and the charging port; calculating a temperature rise value at the charging connection point according to the real-time voltage and the real-time charging current of the voltage check point and the real-time resistance of the charging connection point; and the current environment temperature value is obtained, and the temperature value of the charging port is calculated according to the temperature rise value and the current environment temperature value. According to the invention, accurate calculation of the temperature is realized, and the part design at the charging port is simplified.
