<P>PROBLEM TO BE SOLVED: To provide a discharging method of a battery pack by which a battery pack incorporating a protective circuit can be discharged simply and safely. <P>SOLUTION: In the method of processing a battery pack PB having a protective circuit PS and containing a plurality of battery cells C in a case K, a through hole h communicating between the inside and outside of the case K is formed in the case K, and the battery pack PB in which the through hole h is formed is immersed in liquid having electric conductivity. When the battery pack PB is immersed in liquid having electric conductivity after the through hole h is formed in the case K, the liquid can be introduced into the case K through the through hole h. Since the liquid directly touches the electrode of the battery cell C in the case K and a current flows between the electrodes without passing through the protective circuit PS, even the battery pack PB provided with the protective circuit PS can be discharged efficiently. Since the through hole h is simply formed in the case K, preprocessing for discharge processing can be performed simply and easily. <P>COPYRIGHT: (C)2012,JPO&INPIT |
