摘要： A constant-current battery charger includes a power supply for supplying a charge current to a secondary cell, and a current monitor for monitoring a charge current being supplied to the cell. A controller is included for varying the charge current in accordance with the monitored charge current. The controller calculates a current difference between a predetermined target current and the instant charge current, and generates a demand of varying the charge current at a first charge rate when the current difference is out of a predetermined range, and varying the charge current at a second charge rate when the current difference is within the predetermined range. The controller generates the demand repeatedly at regular or varying intervals for varying the charge current. The first charge rate is set to be higher than the second charge rate in order to make a rapid charging until it comes close to the target current. Since the current difference between the instant charge current and the target current is relied upon to switch the charge rate between the first and second charge rates, the switching can be made at an exact timing truly indicative of the condition of the battery, which enables a rapid charging, yet assuring to complete the charging successfully.

摘要： A battery charger includes an attachment portion capable of being connected to a plurality of battery packs; a connection unit for connecting one of the battery packs connected to the attachment portion to a charging path; a state detection unit for detecting a state of each of the battery packs; a remaining capacity detection unit; and a charging control unit. The remaining capacity detection unit detects a remaining capacity based on the state of the battery pack detected by the state detection unit after each of the battery pack is charged for a specified period of time. Further, the charging control unit assigns priorities to the battery packs such that one whose remaining capacity detected by the remaining capacity detection unit is closer to a fully charged state thereof has a higher priority, and controls the connection unit to charge the battery packs according to the assigned priorities.

摘要： A charging device includes a charging unit; a detection unit for detecting a temperature and a temperature increasing rate of a rechargeable battery; a controller for controlling the charging unit to supply a charging current to the rechargeable battery; and a compensating unit for setting a value of the first threshold to be greater if the temperature of the rechargeable battery at the time of mounting the rechargeable battery on the charging device is equal to or smaller than a second threshold and smaller if otherwise. The charging unit stops supplying the charging current to the rechargeable battery if the temperature increasing rate is equal to or greater than a first threshold.

摘要： A power tool system with enhanced antitheft capability has a hand-held power tool and a wearable piece worn by the user. The wearable piece incorporates a certification unit which stores an identification code specifying the power tool and transmits the identification code to an authenticator incorporated in the power tool. The authenticator reads the identification code from the certification unit and to provide an authentication signal when the identification code is authenticated to be eligible for a privileged use of the power tool. The power tool is enabled only in response to the authentication signal, and otherwise disabled for avoiding unauthorized use. A communication is established between the certification unit and the authenticator for transmission of the identification code, while the user holds the power tool with the wearable piece carried on.
