The invention discloses an electric engineering machinery cooling system control method and a cooling system. The system comprises an electric heat dissipation system, an integrated air conditioning system and a battery cooling system. The method comprises the steps that monitoring data of a cooling system are obtained, and the refrigeration demand degree of a cab and a battery pack BMS cooling request mode are judged according to the monitoring data; according to the cab refrigeration demand degree and the battery pack BMS cooling request mode, a corresponding refrigeration instruction is executed; and when the refrigeration demand degree of the cab or the cooling request mode of the battery pack BMS is changed, the operation is ended. The monitoring data of a cooling system are obtained, the refrigeration demand degree of a cab and the BMS cooling request mode of a battery pack are accurately judged, a double-electronic-fan independent control mode is adopted to achieve accurate heat dissipation of a condenser and a radiator, and the rotating speed of a compressor and the rotating speed of electronic fans are adjusted in a self-adaptive mode. Therefore, reasonable cooling capacity distribution of the cab and the battery pack is effectively achieved through low energy consumption, and driving comfort and safety are guaranteed.
