The invention discloses a fault diagnosis method, a vehicle and a storage medium, and relates to the technical field of vehicles, the method comprises the steps that the vehicle comprises a battery module and a quick charging connector, and a circuit loop between the battery module and the quick charging connector is provided with a quick charging relay; the method comprises the following steps: detecting a first on-off state parameter of a quick charging relay when the vehicle ends a quick charging mode; and under the condition that the first on-off state parameter meets the adhesion condition of the quick charge relay, acquiring a second on-off state parameter of the quick charge relay when the vehicle is in a power utilization state, and determining whether the quick charge relay has an adhesion fault or not according to the second on-off state parameter. The invention aims to improve the accuracy of fault diagnosis of the fast-charging relay in the vehicle, reduce unnecessary limitations on vehicle performance while ensuring the use safety of the vehicle, and ensure the normal use of the vehicle.
