Method for recycling secondary battery
First Claim
1. A method of recycling secondary batteries comprising:
- a first quality control process including the steps of conducting a first inspection on said secondary batteries, separating said secondary batteries into two or more levels based on a result of said first inspection, and classifying said separated secondary batteries into a first group and a second group according to predetermined levels;
a first reuse process for carrying out a first reuse processing on said secondary batteries separated into said one or more levels and belonging to said first group, said first reuse processing comprising different ways of processing to make said secondary batteries reusable according to individual levels;
a second quality control process including the steps of conducting a second inspection on said secondary batteries belonging to said second group, separating said secondary batteries belonging to said second group into two or more levels based on a result of said second inspection, and classifying said separated secondary batteries into a third group and a fourth group according to predetermined levels; and
a second reuse process for carrying out a second reuse processing comprising different ways of processing to make said secondary batteries reusable according to individual levels.

Abstract
A method featuring the steps of determining a secondary battery collected from a user as to whether it is reusable when being handed over again to the user after recharged, by performing a simple inspection on a site where the battery is received and returned to the user, and transferring the battery to another site for additional detailed inspection to further examine whether the battery is reusable when the determination is such that quality up to the specified capacity is not assured if the battery is given back for further usage to the user only after recharging it. The processes described in the above method can ensure the user that it has a reusable quality to the specified capacity, while the battery can be given back quickly.

25. A system of recycling secondary batteries by receiving and separating said batteries after having used by a user, said system comprising:
-
a shop-level computer located in each of retail shops, said shop-level computer for obtaining and transmitting a user information, a secondary battery information, a result of first inspection conducted on said secondary batteries, and a result of first reuse process;
a factory-level computer located in each of factories, said factory-level computer for obtaining and transmitting a result of second inspection and a result of second reuse process executed on said secondary batteries transferred from each of said shop to said factory; and
a center computer for managing said system, comprising an information receiving section for receiving information from said shop-level computer and another information from said factory-level computer, an information identification section for identifying the information received in said information receiving section, and an information storage section for storing said identified information. - View Dependent Claims (26, 27, 28)
