The invention provides a direct-current storage battery outlet fuse operating state monitoring and protecting device which comprises a comprehensive measurement control module and an external direct-current power supply module. The comprehensive measurement control module is used for collecting state data and environment temperature data of the direct-current storage battery outlet fuse in real time and judging whether the external direct-current power supply module needs to be started or not according to the collected state data and environment temperature data, if yes, the external direct-current power supply module is started, and if not, the external direct-current power supply module is started. Therefore, the working characteristics of the fuse are protected from being influenced by low temperature. According to the invention, dynamic online monitoring of the fuse at the outlet of the storage battery is realized by actually measuring the state data of the fuse and the environment temperature data; the o
