Disclosed are a cruise control method and system for an electric vehicle, a vehicle, a controller and a storage medium. The method comprises the steps of: receiving a cruise start request or a cruise resume request, the cruise start request comprising a target cruise speed V1; if the vehicle meets set cruise conditions, detecting a current vehicle speed V, and setting an intermediate vehicle speed V2that is numerically between the target cruise speed V1and the current vehicle speed V, then calculating a difference between the current vehicle speed V and the intermediate vehicle speed V2, and obtaining a final cruise torque based on the difference and a set initial torque; and adjusting a motor output torque of the electric vehicle according to the final cruise torque so as to propel the vehicle to cruise. The application of the cruise control method and system for an electric vehicle can effectively prevent a cruise control torque from fluctuating, thus ensuring a smoother cruising of the vehicle and improving the driving experience of users.
