Systems and methods for battery charger with safety component
First Claim
1. A battery charger, comprising:
- a 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 the battery in the desired operating mode;
wherein, in the base charging mode, the control circuitry is configured to use power from an 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.

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.

7. 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; and 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 (8, 9)
