This application relates to a system and method for wirelessly charging battery packs. More particularly, the application relates to a system and method for wirelessly charging battery packs stored in a container. In one implementation, the system includes a sealable storage box having a transmitter for transmitting RF power to at least one battery pack stored in the storage box.

Wireless charging system

A power tool system includes a power tool, a power tool battery pack and a battery pack charger. The power tool battery pack is separable from and attachable to the power tool, and electrically connectable to the power tool electrical terminals when attached to the power tool. The power tool battery pack has at least one battery cell, a receiver coil, and a control circuit for controlling the amount of power that is provided to the at least one battery cell. The battery pack charger has at least one transmitter coil for generating a magnetic field which induces a voltage in the receiver coil, and a control circuit for controlling the amount of power that is provided to the transmitter coil.

Power tool battery pack wireless charger

A portable power supply apparatus is provided having reduced impedance losses. The portable power supply apparatus is comprised of: a portable housing; a battery system residing in the housing; and an inverter circuit residing in the housing. The battery system generates a direct current (DC) voltage having a magnitude greater than or equal to a peak value of a desired alternating current (AC) voltage. The inverter circuit receives the DC voltage directly from the battery system, converts the DC voltage to an AC output voltage and outputs the AC output voltage to one or more outlets exposed on an exterior surface of the portable housing.

A portable power supply includes a housing, and power circuitry providing an output AC waveform having a first positive voltage step level, a second higher positive voltage step level, a third lower positive voltage step level, a fourth negative voltage step level, a fifth higher negative voltage step level, and a sixth lower negative voltage step level.

Battery based portable power supply

A control module is included in a battery charger that is adapted to charge a plurality of battery packs of different types or a power tool that is adapted to be powered by at least one of the battery packs. The control module includes a remote sensing module that communicates remotely with one of the battery packs. The control module also includes a battery pack connection module that determines that the one of the battery packs is in electrical communication with at least one of the battery charger and the power tool. The control module also includes a battery pack identification (ID) module that determines a first type of the battery pack based on remote sensing module signals. The control module also includes a charge control module that determines at least one of a charge setting and a discharge setting for the battery pack based on the first type.

Battery pack identification system

A cordless power tool has a housing which includes a mechanism to couple with a removable battery pack. The battery pack includes one or more battery cells as well as a vent system in the battery pack housing which enables fluid to move through the housing. A mechanism is associated with the battery pack to dissipate heat from the battery pack.
