摘要： A system of cordless power tools includes a cordless power tool adapted to removably receive a rechargeable battery pack. The system further includes a battery pack charger and a converter for converting AC electricity to DC electricity. A battery pack interface block is captured between clam shell halves of a battery pack housing and includes a plurality of male blade terminals. The male blade terminals are received within recessed female terminals of a tool terminal block and similarly received by recessed female terminals of the charger. The tool terminal block further includes a pair of male terminals which engage recessed female terminals of the converter.

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： A system of cordless power tools includes a cordless power tool adapted to removably receive a rechargeable battery pack. In each embodiment, the battery pack and the power tool have complementary rails and grooves that aid in aligning the positive and negative blade terminals of the battery pack to the positive and negative tool terminals, respectively, of the power tool. In one embodiment, a keying feature cooperates with a mating keying feature to further align the terminals of the battery pack to the terminals of the power tool. In a second embodiment, the battery pack includes two sets of blade terminals, with each set including a positive blade terminal and a negative blade terminal.
