摘要： A DC power source unit supplies a DC voltage to a power tool through an adapter when a power switch of the tool is turned ON and also charges a battery pack 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 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.

摘要： A DC power source unit supplies a DC voltage to a power tool through an adapter when a power switch of the tool is turned ON and also charges a battery pack used as an alternative power source of the tool when the power tool is not operated. A minimum battery temperature gradient amongst battery temperature gradients ever computed is used to determine whether the battery pack has cooling effect when forcibly cooled by a cooling fan or whether the battery pack has reached a full charge condition. When charging the battery pack is interrupted due to operation of the power tool, 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.

摘要： A full charge condition of a battery is determined based on a battery temperature gradient computed at every sampling time based on two values of detected battery temperatures. However, the battery temperature detected when the level of a charge current is switched does not exhibit an accurate temperature of the battery due to contact resistance existing in contact portion of a battery side terminal and a charger side terminal, resulting in inaccurate detection of the full charge condition. A microcomputer corrects the battery temperatures detected after the level of the charge current is switched and the full charge determination is made through computation of the battery temperature gradient using the corrected battery temperatures.
