The invention relates to the technical field of battery control of pure electric vehicles, and particularly discloses a thermal management control method and system for a power battery of a pure electric vehicle and a vehicle. Comprising the steps of obtaining travel road condition information of a vehicle, determining steady-state driving power and instantaneous driving power of the vehicle according to the travel road condition information, collecting current SOC and second state parameter information of a power battery, determining a to-be-heated temperature data value and an estimated temperature rise duration value of the battery, and determining a to-be-heated temperature of the battery according to the proportion of the estimated temperature rise duration value and the travel duration data value. And performing secondary correction based on the current battery temperature data value, the corrected heating target temperature value and the corrected estimated temperature rise time length value to obtain an execution temperature rise time length value and execute a power battery thermal management control strategy. The relation between the travel duration and the actual thermal management time is considered, and the purpose of the optimal economical efficiency of the whole vehicle in the future travel scene can be achieved.
