Abstract

A portable smart battery booster is needed that can communicate with an electrical or electronic device and adjusts the charging voltage to meet the requirements of electrical or electronic device. A variety of different voltages and currents may be required for different electrical and electronic devices. To facilitate fast charging, smart electrical or electronic devices may desire a higher voltage which is controlled by the smart electrical or electronic device to facilitate a rapid charge mode.

Claims

1. A portable power apparatus for charging an electrical device having a rechargeable battery, the apparatus comprising:

an input configured to receive a signal indicative of a desired output voltage from the electrical device;

at least one rechargeable cell having a cell voltage; and

an output configured to provide power from the rechargeable cell to the electrical device at the desired output voltage selected in response to the desired output voltage signal that is different than the cell voltage.

2. The apparatus of claim 1, wherein the input is unidirectional.

3. The apparatus of claim 1, wherein the signal is a digital signal.

4. The apparatus of claim 1, wherein the rechargeable cell is a plurality of rechargeable cells.

5. A portable power pack for charging a battery of a portable electrical device comprising:

a rechargeable cell having a cell voltage;

an output electrically connected with the cell; and

a controller configured to change the output from a battery pack voltage to achieve a desired output voltage different than the cell voltage, selected in response to a signal from the portable electrical device electrically connected with the controller.

6. The portable power pack of claim 5, wherein the rechargeable cell is a plurality of rechargeable cells.

7. The portable power pack of claim 5, wherein the output is generated by a pulse width modulated (PWM) signal.

8. A method for charging an electrical device by a variable voltage portable power pack, the method comprising:

receiving an desired output voltage signal;

selecting an output voltage of a charger from a desired output voltage based on the desired output voltage signal; and

charging the electrical device with energy transferred from the charger at the desired output voltage.

9. The method of claim 8, wherein a DC/DC converter generates an output voltage.
