METHOD FOR SCREENING USED SECONDARY BATTERY, REBUILT BATTERY PACK, VEHICLE AND BATTERY OPERATED DEVICE INCORPORATING SAME, AND METHOD FOR MANUFACTURING REBUILT BATTERY PACK |
摘要 |
Disclosed are a method for adequately screening used secondary batteries; a rebuilt battery pack that incorporates the used secondary batteries which have been screened by the screening method and have identical characteristics; a vehicle and a battery operated device which use the rebuilt battery pack; and a method for manufacturing a rebuilt battery pack which employs used secondary batteries each of which yet has identical characteristics. The method for screening used secondary batteries includes a resistance measurement step (S2) for measuring the battery resistance (BRD) of a battery (1) the characteristics of which show a bathtub curve with respect to the period of use. The method further includes a resistance determination step (S4) for determining whether the battery resistance (BRD) of the battery (1) is greater or less than a period threshold value (Rp) for identifying to which one of the following periods the battery (1) belongs: an initial high-resistance period (A), a terminal high-resistance period (C), and a middle low-resistance period (B). |
