The invention belongs to the field of electric vehicles, and discloses an enclosed battery box for active heat management of an electric vehicle. The enclosed battery box comprises a battery box body, and a semiconductor chilling plate, an internal fin, a fan, a battery management system and a battery pack which are arranged in the battery box body, wherein the battery box body is an enclosed box body, the fan is arranged at one side of the internal fin; the semiconductor chilling fin is fixed on the inner side wall of the battery box body and connected with the internal fin; the battery management system is used for controlling working states of the fan and the semiconductor chilling plate in real time according to a temperature, which is monitored by the battery management system, in the battery pack, so as to realize active heat management. According to the enclosed battery box, the structure of an existing battery system is not changed, simple switching of a heating manner and a refrigerating manner of the battery pack inside the battery box of the electric vehicle can be realized, relatively high dustproof and waterproof grades can be realized; the battery box has an active heat management control strategy; a heating component and a refrigerating component for a power battery pack are simple and convenient to mount, and the price is low.
