Abstract: Portable power supply with a maximum charge rate feature. The portable power supply includes a power source; a power input unit configured to receive power from an external source; a core charger coupled to the power source and the power input unit; and an electronic processor coupled to the core charger. The electronic processor is configured to receive a power limit value and determine a supportable charge current of the internal power source. The core charger is configured to determine a power-limited current based on the power limit value and an output voltage of the core charger, determine a target output current by comparing the power-limited current and the supportable charge current, and charge the power source with the received power at the target output current.

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 resettable electronic fuse for a high-power device such as a power tool, a battery pack for the power tool, or a battery pack charger. The resettable electronic fuse is connected in a current path of the device and is operable or configured to selectively interrupt current through the resettable electronic fuse based on a detected condition of the device (e.g., a detected fault condition of the device). The resettable electronic fuse is also configured to be reset after a detected fault condition has ended. In some embodiments, the resettable electronic fuse is configured to reset itself. In other embodiments, the resettable electronic fuse is configured to receive a signal (e.g., from a device controller) to reset.
