Abstract
A temperature measurement device suitable for measuring the temperature of each secondary battery to consider a temperature deviation between secondary batteries that may occur during charging/discharging in the formation process and capacity test after the secondary battery assembly process, and a charge/discharge apparatus including the temperature measurement device are provided. The temperature measurement device is for measuring a temperature of at least one of a plurality of secondary batteries arranged along an X-axis direction, spaced apart from one another, in a standing position, and includes a non-contact temperature sensor unit which is insertable into a spacing between adjacent secondary batteries to measure the temperature of the secondary battery that the non-contact temperature sensor unit faces in a non-contact manner, and a Z-axis transfer device which inserts the non-contact temperature sensor unit into the spacing downward from above the secondary batteries in a Z-axis direction.
