When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
Lighting devices are devices that illuminate work and living places with various light sources. Some lighting devices are powered by rechargeable batteries for convenience of carrying or emergency. The lighting device is typically equipped with two batteries, a first battery for supplying power to the light source and a second battery for charging the first battery in a charger mode, so that the first battery can be continuously supplied with power, thereby improving the cruising ability of the lighting device. However, in the above power supply mode, the lighting device is always directly supplied with power by the first battery, which increases the power supply time of the first battery, so that the power supply time of the first battery and the power supply time of the second battery have a serious imbalance problem, which may shorten the service life of the first battery.
In view of this, embodiments of the present application provide a power supply method and apparatus, an electrical device, an energy storage device, and a lighting system, which use a new power supply mode to supply power to the electrical device, so as to alleviate the problem of short battery life of the lighting device.
The power supply mode of the embodiment of the application is as follows: under the condition that the first interface of the electric equipment is connected with the energy storage equipment, the energy storage equipment or the charging equipment can be determined to be adopted to supply power to the electric equipment according to the voltage value of the first interface. The charging equipment is equipment connected with the energy storage equipment. This power supply mode can make battery and energy storage equipment in the consumer independently supply power to the consumer respectively to battery and energy storage equipment's in the balanced consumer is long when supplying power, thereby prolongs the life of the battery in the consumer, alleviates the short problem of battery life that lighting apparatus exists.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Fig. 1 shows a flowchart of a power supply method applied to a powered device, where the powered device has a first interface according to an embodiment of the present application. The power supply method is detailed as follows:
s101, detecting a voltage value of the first interface.
Since the main execution body of the power supply method provided by the embodiment is the electric equipment, the electric equipment has a function of detecting the voltage value of the first interface. The voltage detection mode is not specifically limited in this embodiment, and technicians can select various detection circuits to implement the voltage detection mode according to needs.
Optionally, the electric device may periodically detect the voltage value of the first interface at any time, or may periodically detect the voltage value of the first interface again when a preset condition is met. For example, the preset condition may be that the power of the first battery of the electric device is exhausted, or the state of the first interface is a condition of connecting an external device.
S102, according to the voltage value of the first interface, under the condition that the first interface is connected with the energy storage device, the energy storage device or the charging device is determined to be adopted to supply power to the electric device, and the charging device is a device connected with the energy storage device.
The first interface can be connected with the energy storage device, and the energy storage device can be connected with the charging device. Therefore, in the case that the first interface is connected to the energy storage device, the following two situations exist at the first interface of the electric device:
(1) The first interface is connected with the energy storage device, but the energy storage device is not connected with the charging device;
(2) The first interface is connected with the energy storage device, and the energy storage device is connected with the charging device.
Because the voltage value output by the energy storage device is inconsistent with the voltage value output by the charging device, the voltage values of the first interface under the two conditions are inconsistent. Therefore, based on this feature, it is possible to determine whether the first interface of the electrical device is in the (1) th or (2) th situation by detecting the voltage value of the first interface.
And when the first interface is in the (1) th condition, determining to adopt the energy storage device to supply power for the electric equipment. When the first interface is in the (2) th condition, determining to adopt the charging device to supply power for the electric equipment.
It should be noted that, as an optional implementation manner of this embodiment, when the first interface is not connected to the energy storage device, the electric device may supply power to the electric device through the first battery that the electric device has.
It should also be noted that, when the energy storage device supplies power to the electrical device, the energy storage device does not charge the first battery, so as to avoid that the first battery in the electrical device directly supplies power to the lighting device all the time. And the charging device may charge the first battery when the charging device is supplying power to the powered device.
In this embodiment, the range of the voltage value output by the energy storage device and the range of the voltage value output by the charging device are not specifically limited, and a technician may select the voltage value according to needs.
By way of example and not limitation, the energy storage device or the charging device may be used to determine whether to use the energy storage device or the charging device to power the electrical device by selecting a suitable first threshold and a suitable second threshold for comparison with the voltage value of the first interface to determine whether the first interface is in the (1) th or (2) th condition according to the range of the voltage value output by the energy storage device and the range of the voltage value output by the charging device.
Based on the above analysis, as an alternative implementation manner of this embodiment, as shown in fig. 2, step S102 may include the following steps:
s201, when the voltage value of the first interface is larger than a first threshold value but smaller than or equal to a second threshold value, determining to adopt the energy storage device to supply power to the electric equipment.
S202, when the voltage value of the first interface is larger than a second threshold value, the charging device is determined to be adopted to supply power to the electric equipment.
The charge of the battery may be represented by a voltage value of the battery. That is, the lower the charge of the battery, the smaller the voltage value of the battery. Therefore, the voltage values of the first battery and the second battery may also represent the respective amounts of electricity.
By way of example and not limitation, the energy storage device has a second battery, and the voltage value output by the energy storage device is the voltage value of the second battery. For example, the voltage value of the second battery ranges from 3V to 4.2V. Wherein, 4.2V is the voltage value of the second battery in the full charge state, and 3V is the voltage value of the second battery in the power exhaustion state. For another example, the voltage value output by the charging device ranges from 4.9V to 5.25V. Based on the above voltage value range, in some embodiments, the first threshold may be set to 3V and the second threshold may be set to 4.2V. When the voltage value of the first interface is greater than 3V but less than or equal to 4.2V, it indicates that the second battery still has available electric quantity, and the first interface is in the (1) th condition. When the voltage value of the first interface is greater than 4.2V, it indicates that the first interface is in the (2) th condition.
S103, under the condition that the energy storage device is determined to be adopted to supply power to the electric equipment, the energy storage device is controlled to supply power to the electric equipment by utilizing the connection between the second interface and the first interface of the energy storage device; or, in the case that it is determined that the charging device is adopted to supply power to the electric equipment, the energy storage device is controlled to transmit the charging current provided by the charging device to the electric equipment through the connection between the second interface and the first interface.
In step S103, no matter whether the energy storage device or the charging device is used to supply power to the power consumption device, the electric energy can be transmitted through the connection between the second interface and the first interface, and only voltage needs to be transmitted between the first interface and the second interface, and data does not need to be transmitted, so that the power supply method is simple and easy to implement.
To sum up, under the condition that first interface connection energy storage equipment, the consumer can only confirm to adopt energy storage equipment or battery charging outfit to supply power for the consumer through the magnitude of voltage of first interface, and not only the implementation is simple, can avoid being directly supplied power to lighting apparatus by the first battery in the consumer all the time moreover. For example, in the process that the energy storage device or the charging device supplies power to the electric equipment, the electric energy generated by the energy storage device or the charging device may supply power to the electric equipment through the first interface, and the electric equipment does not need to be supplied with power through the first battery in the electric equipment, so that the first battery and the energy storage device in the electric equipment may respectively and independently supply power to the electric equipment, and the power supply duration of the first battery and the energy storage device in the electric equipment is balanced, thereby prolonging the service life of the first battery in the electric equipment and alleviating the problem of short battery life of the lighting equipment.
As an optional implementation manner of this embodiment, in step S103, controlling the energy storage device to transmit the charging current provided by the charging device to the electric device through the connection between the second interface and the first interface, further includes the following steps:
and controlling the energy storage equipment to charge the energy storage equipment by using the charging current provided by the charging equipment.
Under the condition that the first interface is connected with the energy storage device and the energy storage device is connected with the charging device, the first battery in the electric device and the second battery in the energy storage device can be charged through the charging device.
In this embodiment, the charging sequence of the second battery and the first battery is not limited, and a technician may select the charging sequence as needed.
In some embodiments, to implement the fast charging function, the charging device may preferentially charge the first battery or the second battery. In another embodiment, to save the overall charging time, the charging device may charge the first battery and the second battery simultaneously.
It should be noted that, in order to avoid repeated charging, when the electric quantities of the first battery and the second battery are greater than a preset value, the charging device may be prohibited from charging the first battery and the second battery, and when the electric quantities of the first battery and the second battery are lower than the preset value, the charging device may be permitted to charge the first battery and the second battery.
As an optional implementation manner of this embodiment, as shown in fig. 3, in a case that the first interface is connected to an energy storage device and the energy storage device is not connected to the charging device, the power supply method further includes:
s301, when the voltage value of the first battery is larger than a third threshold value, controlling the first battery to supply power to the electric equipment;
and S302, when the voltage value of the first battery is smaller than or equal to a third threshold value, controlling the energy storage device to supply power to the electric equipment.
The specific value of the third threshold is not limited in any way, and a skilled person can select the value as required.
By way of example and not limitation, when the voltage value of the first battery is greater than a third threshold, it indicates that the first battery further has an available charge; and when the voltage value of the first battery is less than or equal to the third threshold, indicating that the electric quantity of the first battery is exhausted.
Optionally, the first threshold and the third threshold may be the same or different. For example, the first and second batteries are the same in size and parameters, and the first and third thresholds are the same.
Thus, in the embodiment shown in fig. 3, the first battery may be preferentially selected to supply power to the electric device, and the energy storage device is used as a backup, so that when the power of the first battery is exhausted, the energy storage device supplies power to the electric device.
In some embodiments, in the case that the first interface is connected to the energy storage device, and the energy storage device is connected to the charging device, the first battery, the second battery or the charging device may be selected to supply power to the electric device.
The first battery and the second battery are both rechargeable batteries. In this embodiment, specific types of the first battery, the second battery, the first interface, and the second interface are not limited, and a technician may select the first battery, the second battery, the first interface, and the second interface according to needs. For example, the first battery and the second battery may be selected from a lithium ion battery, a nickel cadmium battery, a nickel hydrogen battery, or a lead acid battery; the first interface and the second interface can be selected from a Micro USB interface, a USB Type-C interface, a Lightning Dock interface or a Mini USB interface.

When the powered device and the energy storage device are detached, the load is powered by the first battery. If the available electric quantity of the first battery is used up, the first control module controls the load to be closed because the voltage of the first interface is zero.
When the electric equipment is connected with the energy storage equipment and the energy storage equipment is not connected with the charging equipment, the first battery or the second battery is switched and selected to supply power to the load through the voltage of the first battery and the voltage of the first interface. For example, the first battery is preferentially used to power the load. If the voltage of the first battery is smaller than or equal to the third threshold and the voltage of the first interface is smaller than or equal to the first threshold, the first control module controls the load to be closed.
When the electric equipment is connected with the energy storage equipment and the energy storage equipment is connected with the charging equipment, the first control module controls the charging current provided by the charging equipment to charge the first battery and/or supply power to the load through the first interface.
