Abstract

In accordance with embodiments of the present disclosure, an information handling system may include at least one information handling resource and a power system for delivering electrical energy to the at least one information handling resource. The power system may include a battery and a direct-current (DC) input for receiving a DC power source for delivering electrical energy to the at least one information handling resource and charging the battery. The power system may be configured to, based on at least one of an operational state the battery and a power mode of the information handling system, configure an input power draw limit via the DC input.

Claims (48)

1. An information handling system comprising:

at least one information handling resource; and

a power system for delivering electrical energy to the at least one information handling resource, the power system comprising a battery, a controller, and a direct-current (DC) input for receiving electrical energy from a DC power source that is configured to deliver the electrical energy to the at least one information handling resource and to the battery for charging the battery;

wherein the controller of the power system is configured to, based on at least one of an operational state of the battery and a power mode of the information handling system, configure an input power draw limit, such that the electrical energy to be received from the DC power source via the DC input does not exceed the input power draw limit, wherein the operational state of the battery is based at least in part on a temperature associated with the battery, a state of charge of the battery, or a health of the battery.

2. The information handling system of claim 1 , wherein the power system is configured to:

determine if the battery is in a diminished state;

configure the input power draw limit in accordance with a continuous power rating associated with information communicated from the DC power source via the DC input if the battery is not operating in the diminished state; and

configure the input power draw limit in accordance with a nominal continuous power rating of the DC power source if the battery is operating in the diminished state.

3. The information handling system of claim 2 , wherein the power system is configured to determine that the battery is in a diminished state if one or more of the following conditions exist:

a temperature associated with the battery is above a threshold temperature;

a state of charge of the battery is below a threshold state of charge; and

a health of the battery is below a threshold level of health.

4. A power system for delivering electrical energy to at least one information handling resource, the power system comprising:

a battery;

a direct-current (DC) input for receiving electrical energy from a DC power source that is configured to deliver the electrical energy to the at least one information handling resource and to the battery for charging the battery; and

a controller configured to, based on at least one of an operational state of the battery and a power mode of the information handling resource, configure an input power draw limit, such that the electrical energy to be received from the DC power source via the DC input does not exceed the input power draw limit, wherein the operational state of the battery is based at least in part on a temperature associated with the battery, a state of charge of the battery, or a health of the battery.

5. The power system of claim 4 , wherein the controller is further configured to:

determine if the battery is in a diminished state;

configure the input power draw limit in accordance with a continuous power rating associated with information communicated from the DC power source via the DC input if the battery is not operating in the diminished state; and

configure the input power draw limit in accordance with a nominal continuous power rating of the DC power source if the battery is operating in the diminished state.

6. The power system of claim 5 , wherein the controller is configured to determine that the battery is in a diminished state if one or more of the following conditions exist:

a temperature associated with the battery is above a threshold temperature;

a state of charge of the battery is below a threshold state of charge; and

a health of the battery is below a threshold level of health.

7. An information handling system comprising:

at least one information handling resource; and

a power system for delivering electrical energy to the at least one information handling resource, the power system comprising a battery, a controller, and a direct-current (DC) input for receiving electrical energy from a DC power source that is configured to deliver the electrical energy to the at least one information handling resource and to the battery for charging the battery;

wherein the controller of the power system is configured to, based on at least one of an operational state of the battery and a power mode of the information handling system, configure an input power draw limit, such that the electrical energy to be received from the DC power source via the DC input does not exceed the input power draw limit;

wherein the power system is configured to:

determine if the battery is in a diminished state;

configure the input power draw limit in accordance with a continuous power rating associated with information communicated from the DC power source via the DC input if the battery is not operating in the diminished state; and

configure the input power draw limit in accordance with a nominal continuous power rating of the DC power source if the battery is operating in the diminished state.

8. The information handling system of claim 7 , wherein the power system is further configured to determine that the battery is in a diminished state if one or more of the following conditions exist:

a temperature associated with the battery is above a threshold temperature;

a state of charge of the battery is below a threshold state of charge; and

a health of the battery is below a threshold level of health.

9. A power system for delivering electrical energy to at least one information handling resource, the power system comprising:

a battery;

a direct-current (DC) input for receiving electrical energy from a DC power source that is configured to deliver the electrical energy to the at least one information handling resource and to the battery for charging the battery; and

a controller configured to, based on at least one of an operational state of the battery and a power mode of the information handling resource, configure an input power draw limit, such that the electrical energy to be received from the DC power source via the DC input does not exceed the input power draw limit;

wherein the controller is further configured to:

determine if the battery is in a diminished state;

configure the input power draw limit in accordance with a continuous power rating associated with information communicated from the DC power source via the DC input if the battery is not operating in the diminished state; and

configure the input power draw limit in accordance with a nominal continuous power rating of the DC power source if the battery is operating in the diminished state.

10. The power system of claim 9 , wherein the controller is further configured to determine that the battery is in a diminished state if one or more of the following conditions exist:

a temperature associated with the battery is above a threshold temperature;

a state of charge of the battery is below a threshold state of charge; and

a health of the battery is below a threshold level of health.
