The invention relates to a management method for a storage battery group and the method is used for charging and discharging management on a storage battery group that comprises a plurality of storage battery subgroups. The method comprises the following steps: a, measuring parameters of all storage battery subgroups in a storage battery group and comparing the measured parameters with a corresponded set range to determine whether the parameters exceed the set range; if not, going to step c; b, rejecting a failed storage battery subgroup according to the comparison result between the parameters recorded by all the storage battery subgroups and the set range, carrying out classification on the storage battery groups, combining the storage battery groups with the same kind into a storage battery group and going to step a; c, determining whether the storage battery group whose parameter does not exceed the set range is one that is charged fully; if so, going to step e; d, charging the storage battery group until the charging is finished; and e, handing the storage battery group to a user for discharging. According to the invention, the method is simple; maintenance is convenient; the circuit design is simple; and manufacturing and application costs are low; moreover, service life and an integrated utilization efficiency of a storage battery group are improved.
Description
[0001] This application is a divisional application with an application date of August 7, 2009, an application number of 2009100903977, and inventions named as a battery pack management system and method and a battery pack charging management system and method. technical field [0002] The invention relates to storage battery technology, in particular to a management method for storage battery packs used as energy sources. Background technique [0003] With the rapid development of electric vehicles, the battery used in it has gradually become a research hotspot in this industry. Due to the limited capacity of the battery cell, when it is used as a power source, it is generally combined in series and parallel to form a battery pack. For example, connecting battery packs in series in pure electric vehicles is the preferred power energy solution. However, there are certain differences in performance indicators such as the capacity and service life of each battery cell in the b...
