Abstract: Embodiments described herein provide a modular storage for power tool devices including a charging compartment for power tool battery packs. The modular storage includes a housing, a storage compartment in the housing, and a charger compartment in the housing including a battery pack interface configured to receive a power tool battery pack. The modular storage also includes an AC input receiving universal AC power and an active power factor correction (PFC) converter receiving AC power from the AC input and configured to convert the AC power to a high-voltage DC output. The modular storage further includes a DC-DC converter electrically connected between the active PFC converter and the battery pack interface, the DC-DC converter including an active clamp flyback converter.

Abstract: A power tool including a dual role port, a bidirectional converter device, and an electronic controller. The dual role port is configured to receive power from an external device or provide power to the external device. The bidirectional converter device is connected to the dual role port, and is configured to transfer power from the dual role port to a power source of the power tool. The electronic controller is configured to determine that the external device is connected to the dual role port. The electronic controller is also configured to determine a role of the dual role port. The electronic controller is further configured to control operation of the dual role port.
