Systems and methods for battery charger with internal power source
First Claim
1. A battery charger, comprising:
- control circuitry configured to electrically connect to (i) a power supply, (ii) an internal power source, and (iii) a battery,a safety component coupled to the control circuitry and configured to provide battery-specific charging data to the control circuitry;
wherein the control circuitry is configured to operate the battery charger in at least two modes;
(i) a base charging mode and (ii) a fast charging mode;
wherein in the base charging mode, the battery charger is configured to concurrently charge (i) the battery at a base C-rate by using current from the power supply and (ii) the internal power source at the base C-rate by using current from the power supply; and
wherein in the fast charging mode, the battery charger is configured to charge the battery using the internal power source at a high C-rate, and wherein the high C-rate is higher than the base C-rate;
wherein the control circuitry is configured to enable the fast charging mode in response to receiving battery-specific data from the safety component indicating the battery is capable of handling charging at the high 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. The battery charger may include an optical reader used to identify battery-specific characteristics and enable the fast charging mode.

11. A battery charger, comprising:
-
a power supply connector configured to connect the battery charger to an external power supply; a connector configured to connect the battery charger to a battery; an internal power source; a set of one or more switches configured to switch the battery charger between a plurality of operating modes comprising;
(i) a base C-rate charging mode where the battery charger supplies power, from the external power supply at a base C-rate, to the battery and the internal power source and (ii) a high C-rate charging mode where the battery charger supplies power at a high C-rate from the internal power source to the battery, wherein the high C-rate is higher than the base C-rate; andcontrol circuitry configured to switch the battery charger to the high C-rate charging mode only after receiving an indication that a battery connected to the connector is capable of receiving power at the high C-rate. - View Dependent Claims (12, 13, 14, 15, 16, 17)
