Abstract: A charging module is configured to be removably coupled to a mobile work cart. The charging module includes a housing having a first end, a second end, a front side, and a rear side. The housing defines a cavity in the front side and includes a charging bay located within the cavity. The charging bay is configured to removably receive a battery pack to electrically connect the battery pack to the charging module. The charging module also includes a clamp coupled to the rear side of the housing. The clamp includes a handle portion and an arm. The clamp is movable relative to the housing between a deployed position and a retracted position. The clamp is biased toward the retracted position. The housing defines a recess in the rear side. When the clamp is in the retracted position the arm is received within the recess.

Abstract: A charging box has a housing with first and second ends, charging bays, a cover, and a lock assembly. The charging bays are between the first end and the second end. Each of the charging bays removably receives a battery pack in an insertion direction. The cover pivots on the housing nearer to the second end than to the first end. The cover moves between an open position and a closed position. The lock assembly includes a staple, a slot in the cover, a protrusion coupled to the housing adjacent the staple, and a tether coupled to the housing. The staple is nearer to the first end than to the second end. The staple receives a padlock. The slot receives the staple therethrough. The tether has a distal end with a loop. The loop is receivable about the protrusion.

Abstract: A battery charging system includes a housing and an anti-theft mechanism. A battery pack can be coupled to the housing. The battery pack includes release buttons that allow removal of the battery from the housing. An anti-theft mechanism is coupled to the housing. The anti-theft mechanism includes an arm, a cover, and a lock. The arm extends away from the housing and can be engaged by a battery pack. The arm is movable in response to engagement by the battery pack. The cover is movable from a retracted position to a deployed position in response to the battery pack engaging the arm. The cover is configured to cover the release buttons in the deployed position. The lock is coupled to the housing and has a locked mode and an unlocked mode and is configured to maintain the cover in the deployed position when in the locked mode.

Abstract: Systems and methods for providing notifications regarding battery pack charging status. One charging system includes a battery charger and an external device. The battery charger includes a housing, a battery pack interface, a wireless communication controller, and a charger controller. The charger controller receives status information associated with power tool battery packs and transmits the status information to an external device. The external device includes a display and an external device controller. The external device controller receives the status information from the charger controller and controls the display to display the status information via a user interface.
