[0037] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0038] This disclosure provides a power supply method, see [link to relevant documentation] Figure 1 , Figure 1 This is a flowchart of a power supply method provided in an embodiment of this disclosure, which is applied to a combined system, such as... Figure 2 As shown, the integrated system includes a base station power supply system and a battery swapping cabinet subsystem. The base station power supply system includes power supply equipment, a first energy storage device, and base station electrical equipment. The power supply equipment and the first energy storage device are respectively used to supply power to the base station electrical equipment. The power supply equipment is used to charge the first energy storage device. The battery swapping cabinet subsystem includes multiple second energy storage devices, which are used to supply power to the base station electrical equipment, such as... Figure 1 As shown, the power supply method includes the following steps:

[0039] Step 101: When the power supply equipment stops operating, obtain the total backup power duration of the base station power equipment, the first power supply duration of the first energy storage device, and the second power supply duration of the plurality of second energy storage devices.

[0040] In this disclosure, the aforementioned base station power supply system can be a power supply system installed within the base station, and the aforementioned battery swapping cabinet subsystem can be a power supply system installed within the battery swapping cabinet; the aforementioned power supply equipment can stop operating when the mains power source within the base station is interrupted, i.e., when the mains power is cut off.

[0041] It should be noted that in the event of a mains power outage, the base station can receive backup power information transmitted from a remote server. By parsing the backup power information, the total backup power duration of the base station's electrical equipment can be obtained. The total backup power duration can be defined as the total duration during which the base station's electrical equipment needs to operate with the support of the energy storage device in the event of a mains power outage.

[0042] The first power supply duration of the first energy storage device can be: the duration during which the base station equipment can operate with the power supply support of the first energy storage device. The first energy storage device will stop supplying power to the base station equipment when it discharges to the first capacity threshold, so as to avoid the problem of shortening the service life due to over-discharge of the first energy storage device.

[0043] The second power supply duration of the plurality of second energy storage devices can be: the duration during which the base station equipment can operate with the power support of the plurality of second energy storage devices, wherein the power supply support to the base station equipment will be stopped when the second energy storage device discharges to the second capacity threshold, so as to avoid the problem of shortening the service life due to over-discharge of the second energy storage device.

[0044] Step 102: When the first power supply duration is less than the total backup power duration, and the sum of the first power supply duration and the second power supply duration is greater than or equal to the total backup power duration, power is supplied to the base station equipment based on the first energy storage device and the plurality of second energy storage devices.

[0045] In this embodiment of the disclosure, by connecting the base station power supply system and the battery swapping cabinet subsystem, and when the power supply equipment of the base station power supply system stops operating, the base station power supply equipment is powered by the first energy storage device of the base station power supply system and multiple second energy storage devices of the battery swapping cabinet subsystem, so as to reduce the number of first energy storage devices configured in the base station while ensuring the power supply safety of the base station, thereby reducing the base station operating cost.

[0046] In this disclosure, power can be supplied to the base station equipment based on the first energy storage device first, and after the first energy storage device discharges to the first capacity threshold, power can be supplied to the base station equipment based on multiple second energy storage devices; or power can be supplied to the base station equipment based on the first energy storage device and multiple second energy storage devices simultaneously.

[0047] It is important to emphasize that with the rapid development of delivery services such as food delivery and express delivery, the number of battery swapping cabinets is also gradually increasing. Moreover, many of the secondary energy storage devices in the battery swapping cabinets are idle during the early morning hours (e.g., from 0:00 to 6:00), while the mains power outage time of the base station is usually also during the early morning hours. Therefore, by connecting the discharge circuit of the battery swapping cabinet to the power supply circuit of the base station, the multiple idle secondary energy storage devices in the battery swapping cabinet can be utilized, thereby reducing the operating cost of the base station.

[0048] For example, the number of target battery swapping cabinets connected to the power supply circuit of the base station can be one. In this case, it is preferable to set the battery swapping cabinet closest to the base station as the target battery swapping cabinet. The number of target battery swapping cabinets connected to the power supply circuit of the base station can also be N (N is an integer greater than 1). In this case, it is preferable to set the N battery swapping cabinets closest to the base station as the target battery swapping cabinets.

[0049] In one embodiment, when the supply voltage of the first energy storage device is greater than the supply voltage of the second energy storage device, an inverter can be used to adjust the supply voltage of the second energy storage device so that the actual voltage of the base station power supply device output by the second energy storage device is consistent with the supply voltage of the first energy storage device.

[0050] In one embodiment, supplying power to the base station equipment based on a first energy storage device and the plurality of second energy storage devices includes:

[0051] The first energy storage device supplies power to the base station's electrical equipment and obtains the operating voltage of the base station's electronic system.

[0052] When the operating voltage is less than or equal to a preset voltage threshold, the base station equipment is powered by the second energy storage device.

[0053] In this embodiment, by monitoring the operating voltage of the base station's power supply system in real time, and determining that the remaining power of the first energy storage device is insufficient when the operating voltage is less than or equal to the voltage threshold, the power supply to the base station's electrical equipment is switched to the second energy storage device to avoid the base station's electrical equipment from losing power due to unstable power supply, thus enabling the base station's electrical equipment to maintain a stable operating state.

[0054] In one embodiment, obtaining the second power supply duration of the plurality of second energy storage devices includes:

[0055] Obtain the battery demand of the battery swapping cabinet subsystem during a power outage period, wherein the power outage period is the period during which the power supply equipment stops operating;

[0056] The difference between the total number of the plurality of second energy storage devices and the required number of batteries is determined as the number of available batteries in the battery swapping cabinet subsystem;

[0057] The second power supply duration is calculated based on the number of available batteries and the power supply duration of a single second energy storage device.

[0058] In this embodiment, the number of available batteries in the battery swapping cabinet subsystem is determined by the difference between the total number of the plurality of second energy storage devices and the number of batteries required. The second power supply duration is calculated based on the number of available batteries and the power supply duration of a single second energy storage device, so as to ensure the normal use of the battery swapping cabinet while utilizing the idle energy storage devices of the battery swapping cabinet to ensure the power supply security of the base station.

[0059] For example, if the battery swapping cabinet subsystem requires 2 batteries during a power outage and the total number of secondary energy storage devices is 10, then the available number of batteries in the battery swapping cabinet subsystem is 8.

[0060] The process of obtaining the power supply duration of a single second energy storage device can be as follows: obtaining the power supply capacity of a single second energy storage device from a fully charged state to a second capacity threshold, and determining the ratio of the power supply capacity to the instantaneous load of the base station power equipment as the power supply duration of a single second energy storage device.

[0061] In one embodiment, obtaining the battery demand of the battery swapping cabinet subsystem during a power outage includes:

[0062] The battery swapping cabinet subsystem acquires multiple battery replacement data during power outages, with each of the multiple battery replacement data corresponding to a different historical date.

[0063] The average of multiple battery replacement data is determined as the number of batteries required by the battery swapping cabinet subsystem during power outages.

[0064] In this embodiment, the battery demand quantity is determined by calculating the average of multiple battery replacement data during power outage periods on different historical dates for the battery swapping cabinet subsystem, making the obtained battery demand data more reliable, which can further ensure the normal use of the battery swapping cabinet.

[0065] For example, if the battery swapping cabinet subsystem has multiple battery replacement data of 5, 6, 7, 8, and 9 during the power outage period, then the battery demand of the battery swapping cabinet subsystem during the power outage period is 7.

[0066] In one embodiment, the method further includes:

[0067] If the sum of the first power supply duration and the second power supply duration is less than or equal to the total backup power duration, the base station power supply equipment is powered based on the first energy storage device and the plurality of second energy storage devices, and an alarm message indicating that the backup power time of the base station power supply equipment is insufficient is output.

[0068] In this embodiment, when the power supply duration of the first energy storage device and the multiple second energy storage devices cannot meet the total backup power duration, the power supply of the base station equipment is based on the first energy storage device and the multiple second energy storage devices. This can ensure the power supply stability of the base station equipment in the early and middle stages of the total backup power duration. The output of alarm information indicating that the backup power time of the base station equipment is insufficient can remind the backup power personnel of the base station to go to the base station to manually generate electricity, so as to ensure the power supply stability of the base station equipment in the later stages of the total backup power duration.

[0069] It should be noted that if the sum of the first power supply duration and the second power supply duration is less than or equal to the total backup power duration, a backup power assistance request can be sent to the cloud server. If the cloud server provides backup power assistance information based on the backup power assistance request, the undischarged second energy storage device in the battery swapping cabinet subsystem can be controlled to supply power to the base station equipment based on the backup power assistance information. At this time, the number of second energy storage devices in the battery swapping cabinet subsystem used to supply power to the base station equipment is greater than the number of available batteries in the battery swapping cabinet subsystem.

[0070] In one embodiment, after supplying power to the base station equipment based on the first energy storage device and the plurality of second energy storage devices, the method further includes:

[0071] When the power supply equipment resumes operation, the base station equipment is supplied with power based on the power supply equipment, and the first energy storage device is charged based on the power supply equipment.

[0072] In this embodiment, when the power supply equipment resumes operation, that is, when the mains power is restored, the power supply equipment is restored to the base station equipment, and the first energy storage device is charged based on the power supply equipment to replenish the energy consumed by the first energy storage device during the backup power process.

[0073] For ease of understanding, the following example is provided:

[0074] This disclosure also provides a power supply management system, such as... Figure 3 As shown, the power supply management system includes: a cloud platform, an edge computing box, a power system for the battery swapping cabinet, an environmental monitoring system for the base station, a power control matrix, n 24V batteries, a switching power supply, a base station load, and m 48V batteries.

[0075] The cloud platform and the edge computing box are connected in communication. One end of the edge computing box is electrically connected to the power system of the battery swapping cabinet, and the other end of the edge computing box is electrically connected to the environmental monitoring system of the base station. The power system of the battery swapping cabinet controls the charging and discharging of n 24V batteries through a power control matrix. The environmental monitoring system of the base station controls the connection between the base station load and m 48V batteries through a switching power supply. The discharge circuit of the n 24V batteries is connected to the switching power supply through an inverter.

[0076] The above power supply management system can operate as follows: When the edge computing box detects that the base station is currently experiencing a mains power outage, it reports the mains power outage to the cloud platform. Subsequently, the edge computing box receives the total backup power duration from the cloud platform and calculates the first power supply duration of m 48V batteries and the second power supply duration of n 24V batteries. If the first power supply duration is less than the total backup power duration, and the sum of the first power supply duration and the second power supply duration is greater than or equal to the total backup power duration, the base station load is powered based on the m 48V batteries and n 24V batteries. Specifically, the base station load can be powered by the m 48V batteries first. When the operating voltage of the base station is less than or equal to 47.1V, it is determined that the remaining power of the 48V batteries is insufficient, and then the power supply is switched to the n 24V batteries to power the base station load.
