発明の名称: (EN) Method for sorting used secondary battery, rebuilt battery pack, vehicle and battery operated device incorporating same, and method for manufacturing rebuilt battery pack
(ZH) 中古二次电池的挑选方法、重建电池组、使用了该重建电池组的车辆及电池使用设备、以及重建电池组的制造方法
要約: front page image
(EN) 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).
(ZH)

本发明提供一种恰当的中古二次电池的挑选方法、使用了以该挑选方法挑选出的特性一致的中古二次电池的重建电池组、使用了该重建电池组的车辆和电池使用设备、以及使用中古二次电池制造各电池的特性一致的重建电池组的制造方法。本发明的中古二次电池的挑选方法包括电阻测定步骤(S2),针对使用期间的电池电阻(BRD)的特性呈现浴盆状的电池(1)测定其电池电阻(BRD);和电阻判别步骤(S4),判别电池(1)的电池电阻(BRD)是大于期间阈值(Rp)还是小于期间阈值(Rp),所述期间阈值(Rp)是用于识别电池(1)是处于初期高电阻期间(A)或者终期高电阻期间(C)、还是处于中期低电阻期间(B)的阈值。
