摘要： In a cordless power tool system, high temperature gases created in a battery pack by the battery cells during a charging or discharging operation can be routed into a housing of one of an attached power tool or charger to reduce the temperature of the gases, prior to venting the gases externally. In an example, a battery pack has at least one vent hole for relieving pressure and a movable device covering the vent hole and configured to expose the vent hole upon a pressure set-point within the pack housing being exceeded. In another example, the pack housing includes a thin-walled section designed to break if pressure within the pack housing exceeds a given pressure setpoint. In a further example, the pack housing includes a baffle having an S-shaped cross-section for providing a vent path for gases and for preventing external fluids from entering the pack housing.

摘要： A battery monitor system that determines battery pack temperature and battery pack identification. The battery pack includes a battery pack circuit having a thermistor and an AC circuit component. The battery monitoring system determines the battery pack temperature by measuring the resistance of the thermistor when the battery pack circuit is in a steady-state condition, and determines the value of the AC component based on a changing or dynamic electrical condition of the battery pack circuit. In one embodiment, to determine battery pack identification, an identification capacitor is connected in circuit with the thermistor. One terminal of a comparator is switched to a low reference voltage potential once the identification capacitor has been charged, and the output of the comparator gives an indication of the discharge rate of the capacitor, and thus its identification. In an alternate embodiment, the battery monitor circuit determines the identity of the battery pack by determining whether a thermistor does or doesn't exist, and if so, whether an identification capacitor does or doesn't exist.

摘要： In a method of charging a battery pack, the pack is inserted in a charger and an initial set of checks of cell voltage and pack temperature is performed. Once the initial set of checks is satisfied, the cells may be charged at a first constant current level. The first constant current level is adjusted to one or more lower levels of constant current until cell voltages of all the cells are within a full charge voltage window. The voltage window is defined between a minimum full charge cell voltage level and a maximum full charge cell voltage level. The charge may be terminated once all of the cells are within the full charge voltage window.
