摘要： A method for charging and monitoring a rechargeable battery is proposed. Th e charging method includes charging a rechargeable battery, sensing temperatur e of said battery, and calculating temperature change rate. The method further includes sensing voltage of said battery after the temperature change rate reaches a predetermined value, calculating voltage change rate, and reducing current sent to the battery when the voltage change rate reache s a predetermined value. A second embodiment of the charging method may include charging a rechargeable battery, sensing temperature and voltage of said battery, and calculating temperature and voltage change rates. The method further includes sensing for a maximum voltage change rate after the temperature change rate reaches a predetermined value, and reducing current sent to the battery when the maximum voltage change rate is sensed. In addition, the method may include sensing for a minimum voltage change rate before sensing for the maximum change rate, wherein sensing for the maximum change rate would begin after the temperature change rate reache s a predetermined value or after the minimum voltage change rate is sensed.

摘要： A battery monitoring device of a battery pack configured for powering a cordless power tool may include an integrated circuit connected to a microprocessor of the pack that is external to the integrated circuit, and which is connected to each of N battery cells of the pack. The integrated circuit may be configured to take, singly or sequentially, a sampled reading comprising one of an individual cell voltage or a total pack voltage for all cells in the pack. The sampled reading is filtered in the integrated circuit prior to being read by the microprocessor.

摘要： The charging method includes providing a current to the battery pack, sensing battery temperature, determining temperature change rate, and disabling termination of the charging method based on a temperature-based scheme if the temperature change rate exceeds a first predetermined threshold within a first predetermined period of time. Termination of the charging method based on a temperature-based scheme may be re-enabled if the temperature change rate is less than a second predetermined threshold. Preferably the second predetermined threshold is equal to the first predetermined threshold. Alternatively, termination of the charging method based on a temperature-based scheme may be re-enabled after a second predetermined period of time has elapsed. Also disclosed herein is a battery charging method comprising providing a current to the battery pack, sensing battery temperature, determining temperature change rate, and suspending the current if the temperature change rate exceeds a first predetermined threshold within a first predetermined period of time. Current will be re-sent if the temperature change rate is less than a second predetermined threshold. Preferably the second predetermined threshold is equal to the first predetermined threshold. Alternatively, current will be re-sent after a second predetermined period of time has elapsed.

摘要： A method for controlling the operation of a motor utilizing a universal motor control module. The method includes sampling at least one motor operating criterion during operation of the motor and executing a universal control algorithm at a predetermined periodic interval of an AC line signal. Execution of the algorithm provides a firing angle solution for an electronic valve (34) for each periodic interval, thereby controlling the behavior of the motor. Additionally, the method includes firing the electronic valve (34) at the calculated firing angle during each periodic interval such that the motor functions in accordance with desired operational parameters.

摘要： In a cordless power tool system, a battery pack which may removably attachable to a cordless power tool and to a charger may include at least one battery cell and a power limiting device. The power limiting device may be arranged in series with the at least one battery cell for limiting power output of the battery pack based on the component that is connected to the pack. Current and hence power out of the battery pack may be controlled as a function of total internal impedance in the battery pack, which may be adjusted depending on the component that is connected to the pack.

摘要： An ultra-quick charging device for charging battery packs having a wide range of output voltages. The charging device includes an AC to DC high current power supply circuit and a microcomputer-based controller circuit for monitoring the voltage of the battery and converting from fast charge to trickle charge when the second inflection point in the battery voltage charge curve is detected. In order to permit the device to charge battery packs of different rated voltages, the device includes a logarithmic analog-to-digital converter circuit having a selectable prescaler circuit that attenuates the battery voltage signal. The microcomputer is programmed to automatically set the appropriate attenuation level of the prescaler circuit at the outset of the charging cycle by assuming that the maximum voltage of the battery pack being charged will be less than or equal to 150 percent of its observed battery voltage. The present invention is able to automatically fully charge battery packs ranging in voltage between 3 volts and 24 volts.

摘要： An ultra-quick charging device for charging battery packs for an assortment of different appliances, such as power tools, having a wide range of output voltages. The charging device includes an AC to DC high current power supply circuit and a microcomputer-based controller circuit for monitoring the voltage of the battery and converting from fast charge to trickle charge when the second inflection point in the battery voltage charge curve is detected. In order to permit the device to charge battery packs of different rated voltages, the device includes a logarithmic analog-to-digital converter circuit having a selectable prescaler circuit that attenuates the battery voltage signal. The microcomputer is programmed to automatically set the appropriate attenuation level of the prescaler circuit at the outset of the charging cycle by assuming that the maximum voltage of the battery pack being charged will be less than or equal to 150 percent of its observed battery voltage following the initial settling period of the charge cycle. In this manner the present invention is able to automatically fully charge battery packs ranging in voltage between 3 volts and 24 volts.
