Document Type and Number:
WIPO Patent Application WO/2019/139293
Kind Code:
A1
Abstract:
The present invention relates to a secondary battery charging-discharging device and a secondary battery activation process device comprising same. The charging-discharging device of the present invention comprises: a box-type body including two open parts formed at lateral surfaces thereof; charging-discharging terminals disposed on lateral surfaces of the body; a nonflammable blocking means for opening or closing the open parts at the lateral surfaces; an air conditioning line connected to the inside of the body to individually control the temperature of each charging-discharging device; and/or a CO 2 supply line for spraying carbon dioxide inside the body when a fire occurs. According to this configuration, it is possible to uniformly control and manage the internal temperature of a charging-discharging device for performing an activation process of a secondary battery, and when a fire occurs, the fire can be immediately and efficiently extinguished and prevented from spreading to the outside.
