A method of charging a battery pack is provided. The method includes: electronically connecting a battery pack to a charger; detecting information regarding the battery pack; determining an appropriate charging regime based on the detected information; and applying the charging regime to the battery pack. A battery charger may also provided. The battery charger includes: a first terminal for connecting to a battery pack; a second terminal for connecting to a battery pack, a microprocessor operatively connected to the terminals and configured to receive a signal from at least one terminal regarding a battery pack connected to the terminal and control the charger to select and apply a charging regime to the battery pack according to the signal.

Battery pack chargers and charging method

An internal component arrangement within a battery pack housing having multiple cells and adapted for cordless power tools may provide desired mechanical support to constrain the cells. The housing with internal component arrangement is configured to route sensing wires from the cells to an electronics module of the pack.

Battery pack and internal component arrangement within the battery pack for cordless power tool system

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.

Methods of discharge control for a battery pack of a cordless power tool system, a cordless power tool system and battery pack adapted to provide over-discharge protection and discharge control

In a cordless power tool system, protection methods, circuits and devices are provided to protect against fault conditions within a battery pack that is operatively attached to a power tool or charger, so as to prevent internal or external damage to the battery pack or attached tool or charger. The exemplary methods, circuits and devices address fault conditions such as over-charge, over-discharge, over-current, over-temperature, etc.

Protection methods, protection circuits and protection devices for secondary batteries, a power tool, charger and battery pack adapted to provide protection against fault conditions in the battery pack
