Abstract: Provided are a gas processing system, a control method thereof, and an electrical device. The gas processing system includes: a gas storage container, a controller, and a switch component. The gas storage container has a first gas flow branch configured for communicating with a battery box and supplies a dry gas to the battery box. The controller can acquire a state parameter of a gas in the battery box. The switch component is arranged on the first gas flow branch and can switched between a first state, in which the first gas flow branch is turned on, and a second state, in which the first gas flow branch is blocked. The controller is in communication connection with the switch component, and can control the switch component to be switched from the second state to the first state when the state parameter of the gas acquired satisfies a preset condition.
