The invention relates to the technical field of energy storage, in particular to external power supply equipment of a power distribution automation terminal capable of working at-40 DEG C. The external power supply equipment comprises a cover type structure terminal and a storage battery box, and the storage battery box comprises a sodium battery pack, a heating module, a power supply module, a temperature measurement and control module, a supporting structure, a communication module and the like. The positive electrode of the sodium battery pack belongs to one of Prussian blue, polyanion and layered oxide, the negative electrode of the sodium battery pack is made of a hard carbon material, and the PTC heater in the heating module is a positive temperature coefficient thermistor. The working temperature range is wide, and stable charging and discharging can be carried out in an environment of-40 DEG C to + 60 DEG C; the environment temperature and the battery temperature can be collected in real time; the bat
