摘要： A charging signal Vi responding to a charging current is inputted to one input terminal (-) of an operational amplifier 95 forming a comparator and a setting signal Vr corresponding to a setting current value is inputted to the other input terminal (+) of the operational amplifier 95. When the charging signal Vi is not higher than the setting signal Vr, a charging stop signal is generated from the output terminal of the operational amplifier 95 to interrupt a switch unit 4. A starting signal Vcc larger than the setting signal Vr applied to the other input terminal (+) is applied to the one input terminal (-) of the operational amplifier 95 through a condenser 94 till a prescribed time elapses from the start of a charging operation to generate a charging start signal from the output terminal of the operational amplifier 95 and electrically conduct the switch unit 4.

摘要： A DC power source unit (100) supplies a DC voltage to a power tool (4) through an adapter (3) when a power switch (4b) of the tool (4) is turned ON and also charges a battery pack (5) used as an alternative power source of the tool (4) when the power tool (4) is not operated. A minimum battery temperature gradient amongst battery temperature gradients ever computed is used to determine whether the battery pack (5) has cooling effect when forcibly cooled by a cooling fan or whether the battery pack (5) has reached a full charge condition. When charging the battery pack (5) is interrupted due to operation of the power tool (4), computing the battery temperature gradient is halted for some time or determination of the battery pack's full charge condition is not performed for some time in order to prevent the minimum battery temperature from being updated during interruption of charging of the battery pack (5).

摘要： A DC power source unit supplies a DC voltage to a power tool (22) through an adapter when a power switch of the tool (22a) is turned ON and also charges a battery pack (2) used as an alternative power source of the tool when the power tool is not operated. In order to prevent a rush current from flow in a switch (3) interposed between a switching power source circuit and the battery pack when charging the battery pack is commenced, the switch is rendered OFF when the output voltage from the switching power source is greater than the battery voltage. Charging the battery is started upon once lowering the output of the switching power source to a level lower than the battery voltage.
