Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a power management method of a solar rechargeable electronic device according to an exemplary embodiment. The method comprises the following steps:
step 101: detecting the working condition of the electronic equipment and the electric quantity of a main power supply of the electronic equipment; the working conditions include: in a working state, or in a non-working state;
step 102: and when the electric quantity is smaller than a preset low electric quantity threshold value, or when the working condition is in a non-working state, the main power supply is charged by adopting solar energy.
The method determines whether to charge the battery according to the working state of the electronic equipment, and the battery is not charged in the working state, so that the loss of the battery caused by charging and using the battery is avoided; charging the battery in time in a non-working state, and keeping the electric quantity of the battery within a certain range as much as possible; when the electric quantity is too low, even if the working condition also forces to charge, avoid the battery electric quantity too low to use.
Referring to fig. 2, when the remote controller is in a working state, when low electric quantity is detected, whether an emergency mode is started is inquired, and after the emergency mode is confirmed to be started, dual power supplies are used for supplying power to ensure that the remote controller works normally, otherwise, the remote controller is shut down and the electric quantity is detected in real time; when the working state detects that the electric quantity is normal or high, the remote controller works normally to detect the electric quantity in real time.
Referring to fig. 3, when the solar charging device is in a non-working state, low power is prompted when low power is detected, and meanwhile, solar energy is used for automatic charging to detect power in real time; when the normal electric quantity is detected in a non-working state, the solar energy is utilized for automatic charging, and the electric quantity is detected in real time; when the high electric quantity is detected in a non-working state, the solar energy is utilized to automatically charge to enable the solar energy to be maintained (not overcharged) at the high electric quantity, and the electric quantity is detected in real time.
It should be noted that the specific division of the low-charge state, the normal state and the high-charge state of the battery can be determined according to the actual performance of the power supply. In some embodiments, the low battery is 0% to 10%, normally 11% to 95%, and the high battery is 96% to 100%.
The three electric quantity modes of the battery can be adjusted according to actual conditions, and the normal mode of the battery can be from 1% -99% on the premise of not influencing actual use and not damaging the battery, namely 0% of no electric quantity is low electric quantity, and 100% of full electric quantity is high electric quantity.
It is easy to understand that the power management method of the present application is not only applicable to solar rechargeable electronic devices, but also applicable to all low power consumption electronic devices using rechargeable batteries. Such as an air conditioner remote control or a television remote control. For example, most users of notebook computers use the notebook computers when the power supply is plugged, and the notebook computers can manage the power supply by adopting the method, so that overcharge is prevented.

and when the working condition is in a working state and the electric quantity is smaller than a preset low electric quantity threshold value, controlling the electronic equipment to enter a non-working state, and charging the main power supply by adopting solar energy.
Specifically, the low battery threshold may be 10%, that is, the electronic device is forced to enter the non-operating state and be charged when the battery level is lower than 10%.
In some embodiments, the method further comprises:
when the working condition is in a working state and the electric quantity is smaller than a preset low electric quantity threshold value, judging whether to enter an emergency mode;
and if the emergency mode is not entered, controlling the electronic equipment to enter a non-working state, and charging the main power supply by adopting solar energy.

and if the electronic equipment enters the emergency mode, controlling a standby power supply to supply power to the electronic equipment, or continuously adopting the main power supply to supply power to the electronic equipment, and controlling the standby power supply to supply power to the electronic equipment after the electric quantity of the main power supply is exhausted.
In some embodiments, the method further comprises:
and in the charging process, the electric quantity of the standby power supply is preferably fully charged.
In some embodiments, the primary power source and the backup power source are two separate rechargeable batteries; or,
the electric quantity of a rechargeable battery is divided into two parts which are respectively used as a main power supply and a standby power supply.
For example, a battery may be used to divide the power into two portions, with the smaller portion serving as a backup power source.
In some embodiments, the determining whether to enter the panic mode includes:
controlling the electronic equipment to send out emergency prompt information and inquiring whether an emergency mode is started or not;
detecting an operation interface of the electronic equipment;
and if the input confirmation information is detected within the preset waiting time, starting the emergency mode.
In some embodiments, the method further comprises:
and when the electric quantity of the main power supply reaches a preset saturation threshold value, stopping charging the main power supply.
In some embodiments, the method further comprises:
and when the electric quantity of the main power supply is smaller than a preset high electric quantity threshold value, charging the main power supply by adopting solar energy.
Specifically, the high charge threshold may be 96%, and the saturation threshold may be 100%; when the charge is lower than the high charge threshold, the charging is started, and when the charge reaches the saturation threshold, the charging is stopped, so that the battery can be kept at the high charge and can not be overcharged.
The working state and the non-working state can be distinguished according to the existence of the time delay of the key pressing plus a period of time. For example, when a key is pressed, the system immediately enters a working state; when no key press is detected for one minute, the system automatically enters a non-working state.
In some embodiments, the detecting the operation condition of the electronic device includes:
detecting whether an operation interface of the electronic equipment receives an operation signal;
and when receiving the operation signal, judging that the electronic equipment enters a working state and is in the working state all the time within a preset duration.
In some embodiments, the operation interface of the electronic device is: a keyboard, and/or a touch screen;
accordingly, the operation signal is: a key signal, and/or a touch signal.
In some embodiments, the duration is one minute.
In some embodiments, the method further comprises:
and when the electric quantity of the main power supply is smaller than a preset low-electric-quantity threshold value, controlling the electronic equipment to send out low-electric-quantity prompt information.
