Abstract: A battery pack (1) includes a battery cell (3), a leakage detection unit (4) for detecting the leakage of an electrolyte solution of the battery cell (3), a current breaker (5) for electrically interrupting a current line between the battery cell and external terminals (9a, 9b) on occurrence of leakage of the electrolyte solution in the battery cell (3), and a discharging device (6) having the function of self-discharging the battery cell (3). The battery pack is connected to a main equipment body unit (X) or to a charger (Y) to effect discharging or charging, respectively. In a battery cell or a battery pack, employing the battery cell, the malfunction of the battery cell or the battery pack due to leakage of an electrolyte solution may thus be stopped from progressing to prevent occurrence of an accident such as ignition or fuming.

Abstract: There is provided a power storage device including a plurality of modules each including secondary batteries, a charging switch that controls charging to the secondary batteries, a discharging switch that controls discharging of the secondary batteries, and a voltage measuring unit that measures a voltage of the module, and a switch control unit that controls one or both of the charging switch and the discharging switch. The modules are connected in parallel. The switch control unit maintains an on state of the discharging switch for at least one of the modules for a predetermined period, and controls the charging switch of the module in which a maximum module charging current estimated based on the voltage of the module is a predetermined value or less, to be in an on state.

Abstract: A metallic plate and an electrode of, e.g., a polymer lithium ion secondary cell are welded to each other securely so as to further improve the reliability and durability. An upper metallic plate (7a) and a lower metallic plate (9a) of a positive plate are so welded to an electrode (3) of the positive plate that they vertically sandwich the electrode (3). Similarly, an upper metallic plate (7b) and a lower metallic plate (9b) are so welded to an electrode (5) of a negative plate that they sandwich the electrode (5). Thus defective electric resistance welding is prevented.
