Title:
廃電池の放電終了の判断方法及び判断装置
Document Type and Number:
Japanese Patent JP5488335
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an efficient determination method for discharge completion of a waste battery capable of accurately grasping a discharge state of an electrical charge remaining in the waste battery and correctly determining discharge completion without measuring a residual voltage of each of the waste batteries.SOLUTION: In the determination method for discharge completion of a waste battery, after immersion of a waste battery in liquid having conductivity, discharge completion of an electrical charge remaining in the waste battery is determined by measuring concentration of hydrogen gas generated from the liquid.
