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.
Description
technical field [0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2018-0027427 filed on March 8, 2018, and the entire content of this Korean Patent Application is hereby incorporated by reference. [0002] The present invention relates to a charging / discharging device for an activation process of a secondary battery, and more particularly, the present invention relates to a charging / discharging device for an activation process of a secondary battery that after manufacturing a secondary battery The internal temperature of the charging / discharging case can be controlled to be uniform by not allowing external heat generation and temperature difference to affect the inside of the charging / discharging case when the activation process is performed. Background technique [0003] With the development of technology and the increase in demand for mobile devices and the expansion of the popularity of electric vehicles, the demand for secon...
