Abstract: A method, an apparatus, a computer readable media, and a computer program product for detecting a gas leak of a gas tank. The method includes obtaining a gas pressure within the gas tank and a temperature of a tank body of the gas tank; determining an internal average temperature of the gas tank based on the gas pressure; determining a temperature rise of the tank body relative to an ambient temperature; and determining at least one additional characteristic quantity associated with the temperature rise of the tank body. A gas leak of the gas tank can be detected by using the internal average temperature of the gas tank, the temperature rise of the tank body, and the at least one additional characteristic quantity to obtain a predicted relationship between the internal average temperature of the gas tank and the temperature rise of the tank body.
