Abstract

The present invention discloses an integrated charger system that has a construction cordless power tools battery pack and a charger system that is directly, electrically, and mechanically integrated within the construction cordless power tools battery pack to charge an electronic device.

Claims

1. An integrated charger system, comprising:

a construction cordless power tools battery pack; and

a charger system that is directly, electrically, and mechanically integrated within the construction cordless power tools battery pack to charge an electronic device.

2. The integrated charger system as set forth in claim 1, wherein:

the construction cordless power tools battery pack includes;

a housing;

one or more batteries accommodated within the housing;

a main port for charging the one or more batteries and for powering cordless power tools, and

the charger system including a Universal Serial Bus (USB) charger outlet receptacle that is fully integrated with the construction cordless power tools battery pack.

3. The integrated charger system as set forth in claim 2, wherein:

the housing includes;

an inner cavity defined by peripheral walls that partially accommodates the batteries and includes at least one USB charger outlet receptacle within and extending out of a peripheral wall of housing.

4. The integrated charger system as set forth in claim 3, wherein:

the USB charger outlet receptacle is electrically and mechanically coupled with a Printed Circuit Board (PCB).

5. The integrated charger system as set forth in claim 4, wherein:

the USB charger outlet receptacle is electrically and mechanically coupled with one or more batteries through the USB regulator circuit that includes a step down voltage regulator that steps down power input from the one or more batteries and output a substantially constant DC 5 V power to the USB charger outlet receptacle to power and charge the electronic device with a USB cable that is connected to the USB charger outlet receptacle.

6. The integrated charger system as set forth in claim 5, wherein:

the USB regulator circuit further includes;

a main input that is coupled with an output of the battery pack;

a capacitor that reduces power fluctuation and maintains a constant level of voltage, generating a conditioned voltage at the main input;

the capacitor has a first end coupled with the main input and a second end coupled with the ground GND;

the step-down voltage regulator circuit having a first input terminal Vin connected to the main input for receiving the conditioned voltage, and outputting a reduced voltage to the USB charger outlet receptacle for chagrining the electronic device.

7. An integrated charger system, comprising:

a construction cordless power tools battery pack that includes;

a housing;

one or more batteries accommodated within the housing;

a main port for charging the one or more batteries and for powering cordless power tools, and

a charger system within the housing that includes at least one Universal Serial Bus (USB) charger outlet receptacle that is fully integrated with the construction cordless power tools battery pack, with the at least one USB charger outlet receptacle extending out of a peripheral wall of the housing.
