The invention relates to the technical field of electric vehicle heat management, and discloses a battery replacement heavy truck motor waste heat recovery system which comprises a motor water loop system, a battery water loop system, a water chilling unit, a liquid-liquid quick connection plug and a temperature sensor set. And the motor water loop system is also connected with the battery water loop system through a pipeline and a liquid-liquid quick plug. According to the waste heat recovery system for the battery-replacing heavy truck motor, the waste heat of the motor can be recovered in winter, PTC heating used by a battery pack in winter is reduced, and therefore electricity consumption is reduced, the endurance mileage of the battery-replacing heavy truck in winter is increased, in addition, physical isolation of a water path can be achieved through a water chilling unit and a battery pack water loop through a liquid-liquid quick-connection plug, and the service life of the battery pack is prolonged. Therefore, the water cooling unit is removed from the battery pack, and the weight of the battery pack is reduced.
