摘要： There is provided a charging/discharging control device that can protect a chargeable/dischargeable battery cell from an excess current state while preventing the device from being increased in scale and from being complex even in a mode of use in which values of currents flowing in charging and discharging states are considerably different from each other. The charging/discharging control device includes: switches (211) and (212) that are connected in parallel on current paths between a battery (10) and a positive (1a) terminal of a battery pack (1); a switching control unit (22) that switches between a charging current path C and a discharging current path D by turning on the switch (211) and turning off the switch (212) during a charging operation and turning off the switch (211) and turning on the switch (212) during a discharging operation; a protective element (24) that fuses the charging current path C when a current value of the charging current path C flowing through the switch (211) exceeds a first fusing current value; and a protective element (25) that fuses the discharging current path D when a current value of the discharging current path D flowing through the switch (212) exceeds a second fusing current value higher than the first fusing current value.

摘要： To realize a protection member that makes a flux amount applied on a fusible conductor uniform, and improves variation of fusing characteristics because, when a projection portion of a cover member is arranged alone on the fusible conductor, the projection portion is not sufficient to hold flux on the fusible conductor, and the variation is caused in the fusing characteristics. The protection member includes an insulating substrate (11), a heating body (14), an insulating member (15), two electrodes (12), a heating body internal electrode (16), a fusible conductor (13) layered from the heating body internal electrode (16) to the two electrodes (12), and configured to fuse a current path between the two electrodes (12) by heating, flux (17) applied on the fusible conductor (13) to superimpose with the heating body (14), and a cover member (1) covering at least the fusible conductor (13) and attached to the insulating substrate (11). The cover member (1) further includes a plurality of cylindrical projection portions (2) facing the heating body (14) and formed on an inner surface (1a) of the cover member (1) to be in contact with the flux (17).

The heating body electrode (15) is positioned in the same location relative to the first electrode (14a) and the second electrode (14b) which is specified in the thickness direction of the substrate (11).
