The invention provides a hybrid power tractor battery pack thermal management system and a control method. The hybrid power tractor battery pack thermal management system comprises an engine thermal management system and a power battery thermal management system. The power battery and the engine heat management system are controlled to be connected and disconnected through a valve to achieve heat exchange. The control method of the hybrid power tractor battery pack thermal management system comprises an engine and power battery thermal management control method during tractor operation and a power battery thermal management control method during tractor charging. Specifically, the temperature grade of a power battery and the critical working temperature of an engine are set, the real-time temperature T, measured by a temperature sensor, of the power battery and the real-time temperature T, measured by a temperature sensor, of the engine serve as recognition parameters, and the tractor thermal management system mode is adjusted in combination with the tractor state. The heat dissipation loop of the engine is used for heating the battery, so that the power battery works at a proper temperature, the energy consumption is reduced, and the overall energy consumption is reduced.
