摘要： A battery pack 50 has battery cells 80, a switch 180, which may be a FET, for interrupting the discharge current from the battery cells, and a control circuit 140. The switch may be used to interrupt discharge of the battery cells when the battery is in an abnormal operating state based on an indicated temperature condition of a thermistor or a charge state of a fuel gauge.

摘要： Typically, electrical equipment, such as, for example, a cordless power tool, is powered by a rechargeable battery. Battery cells in the present power tool battery may be arranged to reduce the heat transfer between the battery cells. The battery pack is removably locked to the power tool and a terminal assembly may be provided on the battery pack to connect the battery cells to a circuit in the power tool. The terminal assembly may include a sense terminal to allow communication between the battery pack and the power tool or a battery charger. The circuit in the battery pack may include a microprocessor which can monitor various battery pack parameters, such as state of charge and temperature, and may store battery pack characteristics such as nominal voltage and chemistry. The battery pack may include seven battery cells, have a lithium-ion chemistry such as spinel or lithium-manganese, or have a nominal voltage of 28 volts. The battery cells may each have a voltage of 4.2 volts and a capacity of 3.0 ampere-hours. The battery pack may conduct a battery cell voltage equalising method in which the cell voltages are measured and the measuring act provides a discharging act.

摘要： A battery pack 30 includes a charge equaliser to balance the charge across a plurality of cells 46 in the pack 30. The charge equaliser may monitor the battery voltages and discharge the cell 46 with the highest voltage until the charges of the cells 46 are balanced. The battery cells 46 may be arranged in two non-parallel sets to reduce the heat transfer between the cells 46. Data, such as battery chemistry, voltage, or temperature data, may be transferred between the battery cells 46 and a charger. Also claimed is a battery pack 30 for a power tool such as a drill or circular saw.

摘要： A combination including a battery pack and a battery charger operable to supply a charging current to the battery pack. The battery pack includes a first battery terminal, a second battery terminal, and a battery cell having a present state of charge. The battery cell is coupled to at least one of the first battery terminal and the second battery terminal. The battery pack also includes a battery microcontroller coupled to at least one of the first battery terminal and the second battery terminal. The microcontroller is operable to measure the present state of charge of the battery cell to produce battery cell present state of charge measurements. The battery charger includes a first charger terminal configured to couple to at least one of the first battery terminal and the second battery terminal and a second charger terminal configured to couple to at least one of the first battery terminal and the second battery terminal. The first charger terminal is configured to supply charging current to the battery pack. The battery charger also includes a charger microcontroller coupled to the second charger terminal and operable to receive the battery cell present state of charge measurements from the battery microcontroller. The charger microcontroller is also operable to supply the charging current to the battery pack in pulses, wherein each pulse includes a first time interval where charging current is being supplied to the battery and a second time interval where charging current is being suspended from the battery. The microcontroller is further operable to modify the first time interval of a pulse based at least in part on the battery cell present state of charge measurements received from the battery microcontroller.

摘要： Physical protection for at least one battery charger 14 with a battery mounted on its exterior for charging is provided by a separate base 22 with a structure 78 which extends beyond the battery. The structure 78 suitably is formed of bars and provides a detachable handle for the battery charger(s), which is claimed as a distinct aspect. The application also describes and claims an arrangement in which two bases for battery charges can be joined together by their feet (Fig 72) and claims also a charger housing characterised by its relative dimensions.
