Title:
MOBILE TEMPERATURE MEASURING INSTRUMENT FOR SECONDARY BATTERY AND CHARGING/DISCHARGING DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/240379
Kind Code:
A1
Abstract:
Provided are a temperature measuring instrument suitable for measuring the temperature of each secondary battery and a charging/discharging device comprising same for taking into account a temperature variation between secondary batteries that may occur during charging and discharging in a formation process and a capacity inspection after an assembly process of the secondary battery. The temperature measuring instrument according to the present invention is for measuring the temperature of at least one of a plurality of secondary batteries that are arranged upright with one side in the Y-axis facing downward so as to be spaced apart from each other along the X-axis, and comprises: a non-contact temperature sensor unit inserted into the gaps between the secondary batteries to measure the temperatures of the secondary batteries which face each other in a non-contact manner; and a Z-axis feed mechanism for ascending/descending the non-contact temperature sensor unit along the Z-axis to insert the non-contact temperature sensor unit into the gaps downwardly from a position spaced above the secondary batteries along the Z-axis and withdraw the non-contact temperature sensor unit in the opposite direction.
