A charging/discharging system includes a charging/discharging power unit for applying power to a battery cell, a chamber, a jig unit for holding the battery cell mounted in the chamber, an air conditioning unit for adjusting temperature and humidity in the chamber, and an interface unit for controlling the charging/discharging power unit, and for controlling the air conditioning unit, wherein the charging/discharging power unit, the chamber, the air conditioning unit, and the interface unit are combined as an integrated structure.

Charging and discharging system

An apparatus for charging and discharging includes a support portion, first and second racks, first and second vertical partition walls and a pinion. The support portion supports a secondary battery. The first and second racks are moved in a horizontal direction. The plurality of first vertical partition walls are fixed to the first rack at a constant interval. The plurality of second vertical partition walls are provided between the respective first vertical partition walls and fixed to the second rack at a constant interval. The pinion moves the first and second racks in the opposite directions. Accordingly, a charging and discharging operation, a high-temperature aging operation, and the like are performed in a formation process while limiting the expansion of a battery can through a simple operation regardless of differences for each manufacturer and for each model, thereby saving time and, cost.
