    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 includes a battery pack housing, a plurality of battery pack terminals, and a plurality of battery cells supported within the battery pack housing. At least one battery cell includes a battery cell terminal. The battery pack also includes a compound fuse electrically coupled between the battery cell terminal of the at least one battery cell and at least one battery pack terminal. The compound fuse comprises a first material and a second material that has a lower melting point than the first material. The compound fuse includes a first portion electrically coupled to the battery cell terminal, a second portion electrically coupled to the at least one battery pack terminal, and a fuse portion that connects the first portion to the second portion. The fuse portion is configured to establish a discontinuity between the first portion and the second portion during a hard short event.
