Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method for detecting a battery. Background Art

[0002] With the development of communication technology, communication systems play an increasingly important role in the business operations of enterprises. Among them, the communication power supply is the heart of the entire communication system, the key to ensure the safe and reliable operation of the communication system, and the "last line of defense" for the normal operation of communication system equipment. As an alternative power source for the communication power supply, the battery pack is responsible for supplying power to the load in the event of a failure of the communication power supply. It is the basis for ensuring the safe and stable operation of the communication system. Therefore, the maintenance of the battery pack is very important. At present, the capacity and life of the battery pack are mainly tested by regularly conducting battery pack discharge tests. This method not only ensures the safe and reliable operation of the battery pack, but also can discover the potential risks of the battery pack and comprehensively improve the reliability of the operation of the communication system.

[0003] However, in the prior art, when the operator tests the battery pack connected to the communication power supply, the operator must first disconnect the battery pack from the power supply, and then perform a discharge test on the battery pack. For example, when two communication power supplies in a communication station are each connected to a battery pack, the operator must first disconnect the battery pack from the connected communication power supply before discharging one of the battery packs. However, the disconnected communication power supply has no alternative power supply as a backup. If one of the AC inputs of the communication power supply is out of power, the single-channel power supply service will be temporarily interrupted during the switching process of the two AC inputs. Moreover, if both AC inputs of the communication power supply are out of power, the single-channel power supply service will be interrupted for a long time. In addition, when a battery pack is damaged, the battery pack cannot be used as an alternative power supply normally, and there is a risk that there will be no alternative power supply when the communication power supply fails.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0005] The embodiment of the present invention provides a method for detecting a storage battery, so as to at least solve the technical problem of power supply interruption existing in the process of detecting a storage battery in the prior art.

[0006] According to one aspect of an embodiment of the present invention, a method for detecting a battery is provided, comprising: first determining a connection mode between a battery pack and a communication power supply, wherein the battery pack is a backup power supply for the communication power supply, then determining an alternative power supply to replace the battery pack according to the connection mode, and then connecting the alternative power supply to the communication power supply, and disconnecting the battery pack from the communication power supply, and finally performing a discharge detection on the battery pack disconnected from the communication power supply.

[0007] Furthermore, the method for detecting the battery also includes: when there are multiple communication power sources and each communication power source is connected to a battery pack, determining the connection mode to be a first connection mode; when there is one communication power source and the communication power source is connected to multiple battery packs, determining the connection mode to be a second connection mode.

[0008] Furthermore, the method for detecting the battery also includes: when the connection mode is the first connection mode, detecting whether an uninterruptible power supply system is provided in the communication device, wherein the communication power supply supplies power to the communication device. If it is detected that an uninterruptible power supply system is provided in the communication device, determining that the alternative power supply of the first battery group is the uninterruptible power supply system, wherein the first battery group is the battery group connected to the current communication power supply; if it is detected that the uninterruptible power supply system is not provided in the communication device, determining that the alternative power supply of the first battery group is the second battery group, wherein the second battery group is any one of the battery groups connected to other communication power supplies.

[0009] Furthermore, the method for detecting the battery also includes: after determining that the alternative power source of the first battery pack is an uninterruptible power supply system, determining a first load connected to the current communication power supply and a second load connected to the uninterruptible power supply system, and when it is detected that the sum of the first load and the second load is less than the rated power of the uninterruptible power supply system, performing a discharge test on the first battery pack.

[0010] Furthermore, the method for detecting the battery also includes: after determining that the alternative power source of the first battery group is the second battery group, connecting the second battery group in parallel with the first battery group, and disconnecting the connection between the first battery group and the current communication power supply, wherein the second battery group is connected to the current communication power supply via a DC cable.

[0011] Furthermore, the method for detecting the battery also includes: before connecting the second battery group in parallel with the first battery group and disconnecting the connection between the first battery group and the current communication power supply, adjusting the first output voltage of the first battery group and the second output voltage of the second battery group so that the voltage difference between the first output voltage and the second output voltage is less than a preset voltage.

[0012] Furthermore, the method for detecting a storage battery also includes: an isolation device is provided in the DC cable.

[0013] Furthermore, the method for detecting the battery also includes: when the connection mode is the second connection mode, determining the backup battery pack as an alternative power source for the current battery pack, wherein the current battery pack is any one of the multiple battery packs connected to the communication power supply.

[0014] According to another aspect of an embodiment of the present invention, there is also provided a device for detecting a battery, comprising: a first determination module, a second determination module, a processing module, and a detection module. The first determination module is used to determine the connection mode between the battery pack and the communication power supply, wherein the battery pack is a backup power supply for the communication power supply; the second determination module is used to determine an alternative power supply that replaces the battery pack according to the connection mode; the processing module is used to connect the alternative power supply to the communication power supply and disconnect the battery pack from the communication power supply; and the detection module is used to perform discharge detection on the battery pack disconnected from the communication power supply.

[0015] According to another aspect of an embodiment of the present invention, a non-volatile storage medium is provided, wherein a computer program is stored in the non-volatile storage medium, wherein the computer program is configured to execute the above-mentioned method for detecting a storage battery when it is run.

[0016] In an embodiment of the present invention, an alternative power source of a battery pack is connected to a communication power source. When detecting the battery pack, the connection mode of the battery pack and the communication power source is first determined, wherein the battery pack is a backup power source for the communication power source. Then, an alternative power source that replaces the battery pack is determined according to the connection mode, and then the alternative power source and the communication power source are connected, and the connection between the battery pack and the communication power source is disconnected. Finally, a discharge detection is performed on the battery pack disconnected from the communication power source.

[0017] In the above process, before the battery pack is discharged and tested, an alternative power source of the battery pack is first selected according to the connection mode between the battery pack and the communication power source, and the alternative power source is connected to the communication power source. Since the communication power source is already connected to the alternative power source at this time, after the battery pack and the communication power source are disconnected, the communication power source still has an alternative power source, and even if the communication power source has a power outage or other faults at this time, the power supply service will not be interrupted, thereby solving the problem of power supply service interruption in the process of testing the battery pack in the prior art.

[0018] It can be seen that the solution provided in the present application achieves the purpose of ensuring that the communication power supply still has an alternative power supply during the battery pack detection process, thereby achieving the technical effect of improving the stability of the power supply service during the battery pack detection process, and further solving the technical problem of power supply service interruption during the battery pack detection process in the prior art.

[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. Example 1

[0028] According to an embodiment of the present invention, an embodiment of a method for detecting a battery is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 is a flow chart of an optional method for detecting a battery according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:

[0030] Step S102, determining the connection mode between the battery pack and the communication power supply, wherein the battery pack is a backup power supply for the communication power supply.

[0031] In step S102, the battery pack includes but is not limited to: lead-acid batteries, UPS (Uninterruptible Power Supply) batteries and lithium iron phosphate batteries. The communication power supply and the battery pack can be connected in at least two ways, wherein one connection method is as follows: Figure 2 As shown, the DC distribution cabinet 1 and the DC distribution cabinet 2 in the communication station are respectively equipped with a communication power supply 1 and a communication power supply 2, and each communication power supply is connected to a battery pack; another connection method is that there is only one communication power supply in the communication station, and the communication power supply is connected to multiple battery packs.

[0032] Step S104, determining an alternative power source that replaces the battery pack according to the connection mode.

[0033] In step S104, the alternative power source may be a battery pack connected to the communication power source, or a backup battery pack. Depending on the connection mode, the alternative power source of the battery pack may be determined. For example, when there are multiple communication power sources and each communication power source is connected to a battery pack, the existing battery pack connected to the communication power source may be selected as the alternative power source; when there is only one communication power source and the communication power source is connected to multiple battery packs, the backup battery pack may be selected as the alternative power source.

[0034] It should be noted that, through step S104, an alternative power source for the battery pack can be selected in a targeted manner based on the connection method between the battery pack and the communication power source, thereby effectively adapting to various scenarios and ensuring that the battery pack always has a suitable alternative power source during the battery pack detection process.

[0035] Step S106, connecting the alternative power source to the communication power source, and disconnecting the battery pack from the communication power source.

[0036] In step S106, a DC cable may be used to connect the alternative power supply and the communication power supply, wherein the DC cable may be further modified, for example, by providing an isolation device such as a diode.

[0037] Through the above step S106, since the alternative power supply has been connected to the communication power supply before the battery pack is disconnected from the communication power supply, the communication power supply still has an alternative power supply during the detection of the battery pack. Even if the communication power supply has a power outage or other faults at this time, the power supply service will not be interrupted, thereby solving the problem of power supply service interruption in the process of battery detection in the prior art.

[0038] Step S108, performing a discharge detection on the battery pack disconnected from the communication power supply.

[0039] It should be noted that in step S108, the battery pack is discharged to detect the capacity and life of the battery, which can ensure the safe and reliable operation of the battery and discover potential defects of the battery, thereby comprehensively improving the reliability of the communication system operation.

[0040] Through the above steps S102 to S108, the alternative power supply and the communication power supply are connected through a DC cable. When detecting the battery, the connection method of the battery pack and the communication power supply is first determined, wherein the battery pack is a backup power supply for the communication power supply. Then, according to the connection method, an alternative power supply to replace the battery pack is determined, and then the alternative power supply and the communication power supply are connected, and the connection between the battery pack and the communication power supply is disconnected. Finally, the battery pack disconnected from the communication power supply is subjected to discharge detection.

[0041] It is easy to notice that, in the embodiment of the present invention, before the battery pack is discharged, an alternative power source of the battery pack is first selected according to the connection mode between the battery pack and the communication power source, and the alternative power source is connected to the communication power source. Since the communication power source is already connected to the alternative power source at this time, after the battery pack is disconnected from the communication power source, the communication power source still has an alternative power source, and even if the communication power source has a power outage or other fault at this time, the power supply service will not be interrupted, thereby solving the problem of power supply service interruption in the process of battery detection in the prior art.

[0042] It can be seen that the solution provided in the present application achieves the purpose of ensuring that the communication power supply still has an alternative power supply during the battery pack detection process, thereby achieving the technical effect of improving the stability of the power supply service during the battery pack detection process, and further solving the technical problem of power supply service interruption during the battery pack detection process in the prior art.

[0043] In an optional embodiment, the method for detecting the battery also includes: an operator determines a connection mode between the battery pack and the communication power supply, and when there are multiple communication power supplies and each communication power supply is connected to a battery pack, the connection mode is determined to be a first connection mode; when there is one communication power supply and the communication power supply is connected to multiple battery packs, the connection mode is determined to be a second connection mode.

[0044] Optionally, in actual scenarios, the communication power supply and the battery pack are usually connected in two ways, where: Figure 2 As shown, the DC distribution cabinet 1 and the DC distribution cabinet 2 in the communication station are respectively equipped with a communication power supply 1 and a communication power supply 2, each of which is connected to a battery pack. This connection mode belongs to the first connection mode; in addition, when there is only one communication power supply in the communication station, and the communication power supply is connected to multiple battery packs, the connection mode is determined to be the second connection mode.

[0045] In an optional embodiment, the method for detecting the battery further includes: when the connection mode is the first connection mode, the operator detects whether an uninterruptible power supply system is provided in the communication device, wherein the communication power supply supplies power to the communication device. If it is detected that an uninterruptible power supply system is provided in the communication device, it is determined that the alternative power supply of the first battery group is the uninterruptible power supply system, wherein the first battery group is the battery group connected to the current communication power supply; if it is detected that the uninterruptible power supply system is not provided in the communication device, it is determined that the alternative power supply of the first battery group is the second battery group, wherein the second battery group is any one of the battery groups connected to other communication power supplies.

[0046] Optionally, the communication equipment may be a switch, a server or other equipment, and the uninterruptible power supply system may be a UPS power supply system. When the operator determines that the battery pack and the communication power supply are connected in the first mode, the operator detects whether there is a UPS power supply system in the communication equipment. If so, the UPS power supply system is introduced into the AC input of the current communication power supply by temporary wiring, so that the UPS power supply system can be used as an alternative power source to the battery pack connected to the current communication power supply.

[0047] Optionally, when the operator detects that the communication device does not have a UPS power system, any one of the battery packs connected to other communication power supplies is selected as a replacement power source for the battery pack currently connected to the communication power supply. The operator can use a DC cable to connect the battery pack that does not need to be discharged to the power supply of the disconnected battery pack.

[0048] It should be noted that through the above process, the battery pack of a communication power supply can simultaneously serve as an alternative power supply for two communication power supplies, achieving the effect that the power supply service will not be interrupted during the detection of the battery pack.

[0049] In an alternative embodiment, the method for detecting a battery further includes: after the operator determines that the alternative power supply for the first battery pack is an uninterruptible power supply system, determining the first load connected to the current communication power supply and the second load connected to the uninterruptible power supply system, and when it is detected that the sum of the first load and the second load is less than the rated power of the uninterruptible power supply system, performing a discharge test on the first battery pack.

[0050] Optionally, the operator introduces the UPS power supply system into the AC input of the current communication power supply in a temporary wiring manner and disconnects the standby switch of the AC input. Before performing a discharge test on the first battery pack, the operator needs to check the second load connected to the UPS and the first load connected to the communication power supply. When it is detected that the load rate of the UPS can meet the requirements after the first load is connected to the UPS, a discharge test can be performed on the first battery pack. Among them, when verifying whether the remaining capacity of the UPS can meet the capacity of the first load, the operator can use the following formula for calculation: P (first load) = U (voltage) * I (current), P (first load) + P (second load) < P (UPS rated power).

[0051] It should be noted that through the above process, when a power outage occurs at the communication station, the uninterruptible power supply system can invert the AC and supply power to the communication power supply service, avoiding the problem of power supply interruption during the battery pack detection process.

[0052] In an alternative embodiment, the method for detecting a battery further includes: after the operator determines that the alternative power supply for the first battery pack is the second battery pack, paralleling the second battery pack with the first battery pack and disconnecting the connection between the first battery pack and the current communication power supply, where the second battery pack is connected to the current communication power supply through a DC cable.

[0053] Optionally, as Figure 3 shown, the operator needs to detect the battery pack (i.e., the first battery pack) connected to communication power supply 2. Since there is no uninterruptible power supply system set in the current communication equipment, the operator can determine the battery pack (i.e., the second battery pack) connected to communication power supply 1 as the alternative power supply for the first battery pack. The operator first uses a DC cable to connect communication power supply 1 and communication power supply 2, and then disconnects the connection between the first battery pack and communication power supply 2. Then, the operator can perform operations such as a discharge test on the battery pack connected to communication power supply 2.

[0054] It is easy to notice that by using a DC cable to connect the second battery group in parallel with the first battery group, and utilizing the existing battery groups connected to the communication power supply, each battery group can be used as an alternative power source for multiple communication power supplies at the same time, thereby reducing the purchase cost of spare battery groups and alleviating the workload of personnel in carrying spare battery groups.

[0055] In an optional embodiment, the method for detecting batteries also includes: before the operator connects the second battery group in parallel with the first battery group and disconnects the first battery group from the current communication power supply, adjusting the first output voltage of the first battery group and the second output voltage of the second battery group so that the voltage difference between the first output voltage and the second output voltage is less than a preset voltage.

[0056] Optionally, the first output voltage is the output voltage of the communication power supply connected to the first battery group, and the second output voltage is the output voltage of the communication power supply connected to the second battery group, wherein, before connecting the second battery group in parallel with the first battery group, the operator can set the preset voltage to 0.5V and adjust the voltage difference between the first output voltage and the second output voltage to be less than 0.5V.

[0057] It should be noted that in actual scenarios, the communication power supply itself is a power supply device, and the equivalent resistance of the power supply device is small. If two sets of power supply devices with a large difference in output voltage are connected in parallel, the high-voltage power supply device will cause power backflow to the low-voltage power supply device, thereby burning the power supply device and causing greater failures and losses. Therefore, multiple battery packs cannot be connected in parallel unconditionally. It is necessary to adjust the output voltage of the communication power supply corresponding to the battery pack to be basically the same to ensure that the communication power supply works normally during the battery discharge detection process.

[0058] In an optional embodiment, the method for detecting a storage battery further includes: providing an isolation device in the DC cable.

[0059] Optional, such as Figure 4 As shown, the operator can use a DC cable with an isolation device to connect the communication power supply 1 and the communication power supply 2. For example, the isolation device can be a diode, and the negative pole of the DC output of the communication power supply 2 is connected in parallel to the negative pole of the battery pack of the communication power supply 1 using a DC cable with an isolation device, and the positive pole can be connected using an ordinary DC cable. When a voltage difference occurs between the two sets of communication power supplies, the communication power supply with a higher voltage can still supply power to the load normally, but will not backflow power to the communication power supply with a lower voltage.

[0060] It should be noted that, through the above process, the voltage of the communication power supply does not need to be adjusted, so that the problem of power backflow between the communication power supplies due to the voltage difference between the communication power supplies during the detection of the battery pack can be avoided.

[0061] In an optional embodiment, the method for detecting the battery also includes: when the connection mode is the second connection mode, the operator can determine that the backup battery pack is an alternative power source for the current battery pack, wherein the current battery pack is any one of the multiple battery packs connected to the communication power supply.

[0062] Optionally, when a communication power supply is connected to multiple battery packs, the operator can connect a backup battery pack, disconnect the fuse and cable of the current battery pack that needs to be tested, and connect the backup battery pack to serve as an alternative power source for the current battery pack. After confirming that the capacity of the backup battery pack is sufficient, and that the voltage is normal and in a floating charge state after being connected to the system, the operator performs a discharge test on the current battery pack.

[0063] Through the above process, by connecting the backup battery group with the current battery group to be tested, the effect of using the backup battery group as an alternative power source for communication power supply is achieved during the detection of the current battery group, thereby avoiding the problem of power supply interruption during the detection of the current battery group.

[0064] Figure 5 A flow chart of an optional method for detecting a battery according to an embodiment of the present invention is shown to further illustrate the method for detecting a battery pack, wherein: Figure 5 The simulation is Figure 3 The battery pack of the communication power supply 2 in the embodiment of the present invention performs discharge detection, which specifically includes the following steps:

[0065] Step 1: The operator first checks whether the floating charge voltages of the two communication power supplies are consistent. If there is a large difference, manually modify it to a voltage difference of no more than 0.5V;

[0066] Step 2: The operator disconnects the fuse of the communication power supply 1;

[0067] Step 3: The operator connects the DC cables to the positive and negative poles of the battery pack of the communication power supply 1 respectively (each cable must be well insulated);

[0068] Step 4: The operator closes the fuse of the communication power supply 1;

[0069] Step 5: The operator disconnects the fuse of the communication power supply 2;

[0070] Step 6: The operator disconnects the DC cable of the battery pack of the communication power supply 2 and insulates it;

[0071] Step 7: The operator connects the parallel-connected DC cable connected to the battery pack of communication power supply 1 to communication power supply 2;

[0072] Step 8: The operator observes whether there is an alarm on the communication power monitoring panel:

[0073] Step 9: The operator manually simulates a power outage of communication power supply 2 and observes the monitoring panel. At this time, the load is normal;

[0074] Step 10: The operator simulates a fault in the AC input of communication power supply 1 and observes the monitoring panel. At this time, the loads are normal.

[0075] Through the above process, the method for detecting the battery in the embodiment of the present invention achieves the purpose of ensuring that the communication power supply still has an alternative power supply during the battery detection process, thereby achieving the technical effect of improving the stability of the power supply service during the battery detection process, and further solving the technical problem of power supply service interruption in the process of battery detection in the prior art.
