The invention relates to a charging gun with a sealing damage alarm function, which comprises a shell and a charging assembly located in the shell, and is characterized in that the charging gun further comprises a pressure sensor, a temperature sensor and a controller which are located in the shell, and an alarm located outside the shell; when the charging gun charges an electric automobile, the pressure sensor and the temperature sensor monitor the pressure and the temperature in a closed space formed between the charging gun and an automobile body and send measurement results to the controller, and the controller calculates the amount of substance of gas in the closed space according to the measurement results. When the amount of substance of the gas changes, it is judged that the sealing of the charging gun is damaged, and the alarm is indicated to give an alarm. The invention further relates to a corresponding charging pile and a charging method. According to the invention, the sealing condition of the charging gun can be monitored timely and accurately, so that short circuit and other risks during charging are avoided.
