Abstract
A charging and discharging apparatus including a temperature measuring device suitable for measuring a temperature of each secondary battery and a cooling fan for cooling secondary batteries by utilizing temperature information using the temperature measuring device, such that a temperature deviation between the secondary batteries, which may occur during charging and discharging in a formation process and a capacity test after a secondary battery assembly process, is provided. The charging and discharging apparatus includes a movable non-contact temperature measuring device and cooling fans of which directions of wind and outputs are individually adjusted based on temperature information measured by the temperature measuring device according to a location in each secondary battery.
