The invention relates to a hybrid tractor thermal management system, method, device and medium, the system comprises a battery thermal management module and a tractor waste heat management module, the battery thermal management module comprises a battery pack cooling loop, a first battery pack heating loop and a second battery pack heating loop, the tractor waste heat management module comprises an electric drive cooling loop and an engine heat loop. When the current temperature of the battery pack is lower than the battery temperature range and higher than a preset temperature limit value, controlling the electrically-driven cooling loop to exchange heat with the first battery pack heating loop; and when the current temperature of the battery pack is lower than a temperature limit value, an engine thermal loop is controlled to be communicated with a second battery pack heating loop, so that the heated cooling liquid in the engine thermal loop enters the second battery pack heating loop, and the battery pack is heated. The battery pack heating device has the effects of saving resources and improving the battery pack heating efficiency.
