Title:
CHARGING/DISCHARGING DEVICE, HAVING REDUCED TEMPERATURE DIFFERENCE, FOR SECONDARY BATTERY FORMATION PROCESS
Document Type and Number:
WIPO Patent Application WO/2019/172515
Kind Code:
A1
Abstract:
The present invention relates to a charging/discharging device for secondary batteries. The charging/discharging device for secondary batteries comprises: a receiving structure including multiple receiving spaces and having a wire duct arranged at one side of the receiving spaces; multiple charging/discharging boxes installed in the multiple receiving spaces respectively; a wire laid in the wire duct; and an exhaust fan installed within the wire duct, wherein the wire is laid in the wire duct so as to pass along the outer side of the exhaust fan. In addition to the exhaust fan, a heat insulation panel may be further installed within the wire duct. Accordingly, when a secondary battery formation process is performed, the inner space of each charging/discharging box is prevented from being affected by heat generated by the wire, etc., and thus the internal temperature of the inner space can be uniformly regulated and managed.
