    Abstract: A battery charger and a method of operating a battery charger. The charger may include a housing defining an air inlet and an air outlet; a charging circuit operable to output a charging current to charge a battery couplable to the battery charger; a tubular heat sink; and a fan operable to cause air flow from the air inlet to the air outlet and along the heat sink. The charger may include a first switch operable to electrically connect the charging circuit to a power source when the battery engages the charger; and a second switch operable to electrically connect the charging circuit to a battery terminal after the charger terminal is electrically connected to the battery terminal. The charging current or a fan speed may be adjusted based on at least one of the temperature of the charger or a temperature of the battery.

    Abstract: A battery pack may include a battery cell; a resistor operable to receive current from the battery cell; a switch operable to control whether current from the battery cell is provided to the resistor; and an electronic processor coupled to the switch and configured to control the switch to supply current from the battery cell to the resistor. The processor may be configured to detect a failure condition of the battery pack, and, in response, control the switch to discharge the battery cell through the resistor. The processor may be configured to receive a signal from a temperature sensing device indicating the temperature of the interior of the battery pack, determine that the temperature is less than a predetermined temperature threshold, and, in response, close the switch to provide power to the heating element.

    Abstract: 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.
