Abstract
A battery charger with an internal power storage device may be used to facilitate fast charging of a battery by using a high C-rate. A battery charger with an internal power storage device may include a control circuit that receives operating mode instructions to operate in a base charging mode or a fast charging mode. In the base charging mode, the battery charger may be configured to concurrently charge a battery and an internal power storage device at a base C-rate using current supplied from an external power source. In the fast charging mode, the battery charger may be configured to charge the battery at a high C-rate, which is substantially higher than the base C-rate, by using the internal power storage device.

12. A battery charger, comprising:
-
control circuitry configured to couple to a user interface and further configured to electrically connect to (i) a power supply, (ii) an internal power storage device, and (iii) a battery, wherein the control circuit is configured to; receive operating mode instructions from the user interface that correspond to a desired operating mode of (i) a base charging mode or (ii) a fast charging mode; receive battery-specific input from the user interface; and operate the battery charger in the desired operating mode to charge a battery in the desired operating mode; wherein, in the base charging mode, the control circuitry is configured to use power from the external power source to concurrently charge (i) the battery at a base C-rate and (ii) the internal power storage device at the base C-rate; and wherein, in the fast charging mode, the control circuitry is configured to use current from the internal power storage device to charge the battery at a high C-rate, where the high C-rate is higher than the base C-rate. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for operating a battery charger, comprising:
-
receiving operating mode instructions from a user interface, wherein the operating mode instructions correspond to a desired operating mode for charging a battery of (i) a base charging mode or (ii) a fast charging mode; and configuring the battery charger to operate in the desired operating mode, wherein the base charging mode comprises configuring the battery charger to use current from an external power source to concurrently charge both (i) an internal power storage device at a base C-rate and (ii) the battery at the base C-rate, wherein the fast charging mode comprises configuring the battery charger to use current from the internal power storage device to charge the battery at a high C-rate, and wherein the high C-rate is higher than the base charging rate. - View Dependent Claims (19, 20)
