<p><P>PROBLEM TO BE SOLVED: To provide a charge control method for keeping a specific state of charge (SOC) in a case when a storage battery configurated by a plurality of cells and used in a hybrid car and the like is used in a partial state of charge (PSOC), and obtaining stable life characteristic. <P>SOLUTION: In this charge control method to use the storage battery in the partial state of charge (PSOC), a maximum temperature difference among cells in use is controlled to be 15°C or less, and the recovery charge is periodically performed to correct the difference from the PSOC of the storage battery in use. <P>COPYRIGHT: (C)2004,JPO</p> |
