Abstract
A battery connector, an electrical combination and methods. The electrical combination may include a battery connector including a housing with a support portion for a battery pack, and a circuit supported by the housing, the circuit including a universal serial bus (USB) input terminal connectable to a USB cable for receiving power, a charging terminal connectable to a pack terminal of the battery pack, and a battery charging portion operable to receive power from the USB input terminal and to output a charging current to the charging terminal to charge the battery pack.
Claims20
An electrical combination comprising:
- a battery connector including
- a housing with a support portion for a battery pack, and
- a circuit supported by the housing, the circuit including
- a universal serial bus (USB) input terminal connectable to a USB cable for receiving power,
- a charging terminal connectable to a pack terminal of the battery pack, and
- a battery charging portion operable to receive power from the USB input terminal and to output a charging current to the charging terminal to charge the battery pack.
A method of charging a battery pack, the method comprising:
- providing a battery connector including a housing with a support portion for the battery pack and a circuit with a universal serial bus (USB) input terminal and a battery charging portion;
- supporting the battery pack on the support portion;
- electrically connecting the battery pack to the circuit of the battery connector;
- electrically connecting a USB cable between a power source and the USB input terminal of the battery connector;
- receiving, by the battery charging portion of the circuit, power from the USB input terminal;
- and
- outputting a charging current from the battery charging portion to the battery pack to charge the battery pack.
An electrical combination comprising:
- a battery connector separate from a powered device and including
- a housing with a support portion for a battery pack, and
- a circuit supported by the housing, the circuit including
- an input terminal connectable to a power source,
- a charging terminal connectable to a pack terminal of the battery pack,
- an output terminal electrically connectable to the powered device and operable to output power from the battery pack to the powered device, and
- a battery charging portion operable to receive power from the input terminal and to output a charging current to the charging terminal to charge the battery pack.
