Abstract: Methods, apparatuses, systems, computer readable media, and a computer product for detecting a gas leak of a gas tank. In a method, at least one inside temperature is determined for the gas tank based on a plurality of outside temperatures that are collected outside the gas tank, the at least one inside temperature being estimated for at least one inside position within the gas tank during an operation of the gas tank. A gas pressure within the gas tank under a standard temperature is obtained based on the at least one inside temperature. The gas leak of the gas tank is detected based on the gas pressure.
