Abstract

Software and/or hardware to monitor system usage including how long system ran on a battery or with AC adapter power. The software and/or hardware judges whether fast charging is needed and/or how much charge is needed, and optimizes battery charging settings.

First claim

What is claimed is:

1. A non-transitory machine-readable storage media having machine-executable instructions that when executed, cause one or more processors at a computing device to:
record a first battery state-of-charge at an end of a first battery discharge and/or at a beginning of a first battery charge after the first battery discharge or when a battery charger is attached;
record a first time when battery charging starts or when the battery charger is attached;
record a second time when a second battery discharge starts or a battery charger is detached;
record a second battery state-of-charge when a second battery discharge starts or a battery charger is detached;
calculate at least one of a minimum state-of-charge, a charging speed, or a charging time with a battery charger based on at least one of the first state-of-charge and second state-of-charge or a difference between the first time and second time; and
communicate from the computing device to the battery charger to suggest modifying charging settings at the battery charger to limited charging or reduced charging speed based on one or more of the minimum state-of-charge or the difference between the first time and second time.

2. The non-transitory machine-readable storage media of claim 1 having machine-executable instructions that when executed, cause the one or more processors to:
disable the limited charging when the first state-of-charge or second state-of-charge is below a threshold.

3. The non-transitory machine-readable storage media of claim 1 , wherein the limited charging or the reduced charging speed is enabled or disabled by one of, some of, or all of: duration and/or pattern of pressing a button, a pattern to open or close a lid, a pattern to attach or detach a charger, activation of disabling option in software, or activation of a dedicated button or sensor.

4. The non-transitory machine-readable storage media of claim 1 , wherein the limited charging or the reduced charging speed is enabled or disabled as indicated by a light duration, a light pattern, or a light color.

5. The non-transitory machine-readable storage media of claim 1 having machine-executable instructions that when executed, cause the one or more processors to:
apply a machine-learning scheme to determine limits for the limited charging and/or the reduced charging speed.

6. The non-transitory machine-readable storage media of claim 5 , wherein the limited charging and/or the reduced charging speed is adjusted by a machine-learning error.

7. The non-transitory machine-readable storage media of claim 5 , wherein the limited charging and/or the reduced charging speed is adjusted by a temperature of system and/or a battery.

8. The non-transitory machine-readable storage media of claim 5 , wherein the machine-learning scheme includes a neural network to predict limits on one or more of the limited charging or the reduced charging speed.

9. A non-transitory machine-readable storage media having machine-executable instructions that when executed, cause one or more processors to:
access a fuel gauge of a microcontroller of a battery to obtain a first battery state-of-charge of the battery at an end of a first battery discharge and/or at a beginning of a first battery charge after the first battery discharge and/or when a battery charger is attached, and to obtain a second battery state-of-charge of the battery when a second battery discharge starts or the battery charger is detached;
modify charging settings to limited charging based on the first and/or second battery state-of-charge;
record a first time when one or both of battery charging starts or the battery charger is attached;
record a second time when a second battery discharge starts or the battery charger is detached; and
modify charging settings of charging speed based on at least one of a difference between the first time and second time, the first battery state-of-charge, and/or the second battery state-of-charge.

10. The non-transitory machine-readable storage media of claim 9 , wherein to modify the charge settings, the one or more processors are to communicate from the one or more processors to the battery charger to suggest the modifying of the charging settings at the battery charger.

11. The non-transitory machine-readable storage media of claim 9 having machine-executable instructions that when executed, cause the one or more processors to:
calculate a minimum state-of-charge and/or a charging speed based on the first and/or second state-of-charges.

12. The non-transitory machine-readable storage media of claim 11 having machine-executable instructions that when executed, cause the one or more processors to:
modify a percentage of charge termination to at least 100 minus the minimum state-of-charge.

13. A system, comprising:
a display;
a battery to power the display, the battery including a microcontroller;
a processor circuitry to execute one or more instructions, the processor circuitry powered by the battery; and
an interface to connect a charge cable to a battery charger which is to provide power to the system, wherein the processor circuitry or the microcontroller is to:
record a first battery state-of-charge at an end of a first battery discharge and/or at a beginning of a first battery charge after the first battery discharge or when the battery charger is attached;
record a first time when battery charging starts or when the battery charger is attached;
record a second time when a second battery discharge starts or the battery charger is detached;
record a second battery state-of-charge when a second battery discharge starts or the battery charger is detached;
calculate at least one of, a minimum state-of-charge, a charging speed, or a charging time with the battery charger based on at least one of the first state-of-charge and second state-of-charge or a difference between the first time and second time; and
communicate to the battery charger via the interface to suggest modifying charging settings at the battery charger to limited charging or reduced charging speed based on one or more of the minimum state-of-charge or the difference between the first time and second time.

14. The system of claim 13 , wherein the processor circuitry or the microcontroller is to:
disable the limited charging when the first state-of-charge or second state-of-charge is below a threshold.

15. The system of claim 13 , wherein the limited charging and/or the reduced charging speed is enabled or disabled by duration and/or a pattern of pressing a button, a pattern to open/close a lid, a pattern to attach or detach a charger, activation of a disabling option in software, and/or activation of a dedicated button or sensor.

16. The system of claim 13 , wherein the limited charging and/or the reduced charging speed is enabled or disabled as indicated by a light duration, a light pattern, and/or a light color.

17. The system of claim 13 , wherein the processor circuitry or the microcontroller is to:
apply a machine-learning scheme to determine limits for the limited charging and/or reduced charging speed.

18. The system of claim 17 , wherein the machine-learning scheme includes a neural network to predict limits for the limited charging and/or the reduced charging speed.

19. The system of claim 17 , wherein the machine-learning scheme includes models with limited train size and larger than limited train size, wherein the processor circuitry or the microcontroller is to train the models separately or at a same ti
