Abstract

This application provides a drainage method and device for a fuel cell vehicle, comprising: obtaining the vehicle's driving status, including whether the vehicle has entered a parking lot; controlling the on / off state of a drain valve based on the vehicle's driving status, the drain valve being used to control drainage from a water tank for storing liquid water; and collecting the liquid water into the water tank in response to the drain valve being closed. This method, by providing a water tank to collect liquid water from the exhaust pipe, prevents water generated by the vehicle after entering a parking lot from being directly discharged and causing drainage accumulation. Furthermore, this application enables automated vehicle drainage, eliminating the need for special attention and operation by the driver, significantly enhancing the user experience.
