The storage battery pack is used as a substitute power supply of the communication power supply, bears the burden of supplying power to a load under the condition that the communication power supply fails, and is the basis for ensuring the safe and stable operation of the communication system, so the maintenance work of the storage battery pack is very important. At present, the capacity and the service life of the storage battery pack are mainly detected by a mode of carrying out a storage battery pack discharge test regularly, the mode not only ensures the safe and reliable operation of the storage battery pack, but also can discover the potential risk of the storage battery pack and comprehensively improve the operation reliability of a communication system.
However, in the prior art, when an operator detects a battery pack connected to a communication power supply, the operator first needs to disconnect the battery pack from a power supply and then perform a discharge experiment on the battery pack. For example, when two communication power supplies in a communication station are connected with one storage battery pack respectively, an operator needs to disconnect the storage battery pack from the connected communication power supply before discharging one storage battery pack, but the disconnected communication power supply does not serve as a substitute power supply for standby, and if one path of alternating current input of the communication power supply is powered off, the situation that the power supply service is temporarily interrupted in the process of switching the two paths of alternating current input of the one-path power supply is caused. Moreover, if the two ac inputs of the communication power supply are both powered off, the problem of long-time interruption of the single-path power supply service is caused. In addition, when one battery pack is damaged, the battery pack cannot be normally used as an alternative power supply, and there is a risk that there is no alternative power supply when the communication power supply fails.
In view of the above problems, no effective solution has been proposed.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for detecting a battery, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
Fig. 1 is a flow chart of an alternative method for testing a battery according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
and S102, determining a connection mode of a storage battery pack and a communication power supply, wherein the storage battery pack is a standby power supply of the communication power supply.
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 storage battery pack can be connected in at least two connection modes, wherein one connection mode is shown in fig. 2, a direct current power distribution cabinet 1 and a direct current power distribution cabinet 2 in a communication station are respectively provided with the communication power supply 1 and the communication power supply 2, and each communication power supply is connected with one storage battery pack; another way of connection is that only one communication power supply is present in the communication station and that the communication power supply is connected to a plurality of battery packs.
And step S104, determining an alternative power supply of the alternative storage battery pack according to the connection mode.
In step S104, the alternative power supply may be a battery pack to which the communication power supply is connected, or may be a backup battery pack. According to different connection modes, an alternative power supply of the storage battery pack can be determined, for example, when the number of the communication power supplies is multiple and each communication power supply is connected with one storage battery pack, the existing storage battery pack connected with the communication power supply can be selected as the alternative power supply; when the number of the communication power sources is one and the communication power sources are connected to a plurality of secondary batteries, a backup secondary battery may be selected as the substitute power source.
It should be noted that, through step S104, the alternative power supply of the storage battery pack can be selected in a targeted manner based on the connection mode between the storage battery pack and the communication power supply, so as to effectively adapt to various scenes, and ensure that the storage battery pack always has a suitable alternative power supply in the process of detecting the storage battery pack.
And step S106, connecting the alternative power supply and the communication power supply, and disconnecting the storage battery pack from the communication power supply.
In step S106, the alternative power source and the communication power source may be connected by using a dc cable, wherein the dc cable may be further modified, for example, by providing an isolation device such as a diode.
Through the step S106, since the alternative power supply is connected to the communication power supply before the connection between the storage battery pack and the communication power supply is disconnected, the communication power supply still has the alternative power supply during the detection of the storage battery pack, and even if a fault such as power failure occurs in the communication power supply, the power supply service is not interrupted, thereby solving the problem of power supply service interruption during the detection of the storage battery in the prior art.
Step S108 is to perform discharge detection on the battery pack disconnected from the communication power supply.
It should be noted that, in step S108, the discharge detection is performed on the storage battery pack, so as to detect the capacity and the service life of the storage battery, thereby not only ensuring the safe and reliable operation of the storage battery, but also finding out potential defects of the storage battery, and comprehensively improving the reliability of the operation of the communication system.
Through the steps S102 to S108, when detecting the storage battery, the connection mode between the storage battery pack and the communication power supply is determined by connecting the alternative power supply and the communication power supply through the dc cable, wherein the storage battery pack is a standby power supply of the communication power supply, the alternative power supply of the alternative storage battery pack is determined according to the connection mode, the alternative power supply and the communication power supply are connected, the connection between the storage battery pack and the communication power supply is disconnected, and finally, the discharge detection is performed on the storage battery pack disconnected from the communication power supply.
It is easy to note that, in the embodiment of the present invention, before the discharge detection is performed on the secondary battery pack, the alternative power supply of the secondary battery pack is first selected according to the connection manner of the secondary battery pack and the communication power supply, and the alternative power supply is connected with the communication power supply. Because the communication power supply is connected with the alternative power supply, the communication power supply still has the alternative power supply after the connection between the storage battery pack and the communication power supply is disconnected, and even if the communication power supply has faults such as power failure and the like, the power supply service cannot be interrupted, so that the problem of power supply service interruption in the process of detecting the storage battery in the prior art is solved.
Therefore, the scheme provided by the application achieves the purpose that the communication power supply still has a substitute power supply in the process of detecting the storage battery pack, so that the technical effect of improving the stability of the power supply service in the detection process of the storage battery pack is achieved, and the technical problem of power supply service interruption in the detection process of the storage battery pack in the prior art is solved.
In an optional embodiment, the method of testing the battery further comprises: an operator determines the connection mode of the storage battery pack and the communication power supply, and when the number of the communication power supplies is multiple and each communication power supply is connected with one storage battery pack, the connection mode is determined to be a first connection mode; and when the number of the communication power supplies is one and the communication power supplies are connected with the plurality of storage battery packs, determining the connection mode as a second connection mode.
Optionally, in an actual scene, the communication power supply and the storage battery pack are usually connected in two connection manners, where as shown in fig. 2, a direct-current power distribution cabinet 1 and a direct-current power distribution cabinet 2 in the communication station are respectively provided with the communication power supply 1 and the communication power supply 2, each communication power supply is connected with one storage battery pack, and the connection manner belongs to a first connection manner; in addition, when only one communication power supply exists in the communication station and the communication power supply is connected to the plurality of secondary battery packs, it is determined that the connection mode is the second connection mode.
In an optional embodiment, the method of testing the battery further comprises: when the connection mode is the first connection mode, an operator detects whether an uninterruptible power supply system is arranged in the communication equipment, wherein the communication power supply supplies power to the communication equipment. If the communication equipment is detected to be provided with the uninterrupted power supply system, determining that the alternative power supply of the first storage battery pack is the uninterrupted power supply system, wherein the first storage battery pack is a storage battery pack connected with the current communication power supply; and if the uninterruptible power supply system is not arranged in the communication equipment, determining that the alternative power supply of the first storage battery pack is the second storage battery pack, wherein the second storage battery pack is any one of the storage battery packs connected with other communication power supplies.
Optionally, the communication device may be a switch, a server, or the like, and the uninterruptible power supply system may be a UPS power supply system, and when the operator determines that the storage battery pack and the communication power supply are in the first connection mode, the operator detects whether there is a UPS power supply system in the communication device, and if so, introduces the UPS power supply system into the ac input of the current communication power supply in a temporary connection mode, so that the UPS power supply system may serve as an alternative power supply for the storage battery pack connected to the current communication power supply.
Optionally, when the operator detects that the communication device does not have the UPS power system, any one of the battery packs connected to other communication power sources is selected as a substitute power source for the battery pack connected to the current communication power source. The operator can connect the storage battery pack which does not need discharge detection to the electrified power supply of the disconnected storage battery pack by using the direct-current cable.
It should be noted that, through the above process, the battery pack of one communication power supply can simultaneously serve as an alternative power supply for two communication power supplies, and the effect that the power supply service is not interrupted in the process of detecting the battery pack is achieved.
In an optional embodiment, the method of testing the battery further comprises: after determining that the alternative power supply of the first storage battery pack is the uninterruptible power supply system, an operator determines a first load connected with the current communication power supply and a second load connected with the uninterruptible power supply system, and when detecting that the sum of the first load and the second load is greater than the rated power of the uninterruptible power supply system, the operator performs discharge detection on the first storage battery pack.
Optionally, the operator introduces the UPS power system into the ac input of the current communication power supply in a temporary connection manner, and disconnects the backup switch of the ac input. Before discharging detection is carried out on the first storage battery pack, an operator needs to check a second load connected with the UPS and a first load connected with the communication power supply, and when the fact that the first load is connected into the UPS is detected, when the load rate of the UPS can meet the requirement, a discharging test can be carried out on the first storage battery pack. When checking whether the remaining capacity of the UPS can meet the first load capacity, the operator can calculate by adopting the following formula: p (first load) ═ U (voltage) × I (current), P (first load) + P (second load) < P (UPS rated power).
It should be noted that, through the above process, when the communication station has a power failure, the uninterruptible power supply system can supply power to the communication power supply service after inverting the alternating current, thereby avoiding the problem of power supply service interruption in the detection process of the storage battery pack.
In an optional embodiment, the method of testing the battery further comprises: after determining that the alternative power supply of the first storage battery pack is the second storage battery pack, an operator connects the second storage battery pack and the first storage battery pack in parallel and disconnects the first storage battery pack from the current communication power supply, wherein the second storage battery pack is connected with the current communication power supply through a direct current cable.
Optionally, as shown in fig. 3, an operator needs to detect the battery pack (i.e., the first battery pack) connected to the communication power supply 2, and since the current communication device is not provided with an uninterruptible power supply system, the operator may determine the battery pack (i.e., the second battery pack) connected to the communication power supply 1 as a substitute power supply for the first battery pack. An operator first connects the communication power supply 1 and the communication power supply 2 by using a direct current cable, then disconnects the first storage battery pack from the communication power supply 2, and then can perform operations such as discharge detection on the storage battery pack connected to the communication power supply 2.
It is easy to notice that, by adopting a mode of connecting the second storage battery pack and the first storage battery pack in parallel by using a direct current cable, each storage battery pack can be used as an alternative power supply of a plurality of communication power supplies at the same time by using the existing storage battery pack connected by the communication power supply, thereby reducing the purchase cost of the standby storage battery pack and reducing the workload of carrying the standby storage battery pack by personnel.
In an optional embodiment, the method of testing the battery further comprises: before connecting the second storage battery pack and the first storage battery pack in parallel and disconnecting the first storage battery pack from the current communication power supply, an operator adjusts a first output voltage of the first storage battery pack and a second output voltage of the second storage battery pack so that a voltage difference value between the first output voltage and the second output voltage is smaller than a preset voltage.
Optionally, the first output voltage is an output voltage of a communication power supply connected to the first storage battery pack, and the second output voltage is an output voltage of a communication power supply connected to the second storage battery pack, wherein before the second storage battery pack is connected in parallel with the first storage battery pack, an operator may set a preset voltage to 0.5V, and simultaneously adjust a voltage difference between the first output voltage and the second output voltage to be less than 0.5V.
It should be noted that, in an actual scene, the communication power supply itself is a power supply device, and the equivalent resistance of the power supply device is small, and if two sets of power supply devices with a large output voltage difference are connected in parallel, the power supply device with a high voltage will flow backward to the power supply device with a low voltage, and further burn out the power supply device, causing a larger fault and loss, so that a plurality of storage battery packs cannot be connected in parallel unconditionally, and the output voltages of the communication power supplies corresponding to the storage battery packs need to be adjusted to be basically the same, so as to ensure that the communication power supplies normally work in the storage battery discharge detection process.
In an optional embodiment, the method of testing the battery further comprises: an isolation device is arranged in the direct current cable.

It should be noted that, through the above process, the problem of power backflow between the communication power supplies due to the voltage difference between the communication power supplies in the detection process of the storage battery pack can be avoided without adjusting the voltage of the communication power supplies.
In an optional embodiment, the method of testing the battery further comprises: when the connection mode is the second connection mode, the operator can determine that the standby storage battery pack is an alternative power supply of the current storage battery pack, wherein the current storage battery pack is any one of a plurality of storage battery packs connected with the communication power supply.
Optionally, when one communication power supply is connected to multiple storage battery packs, an operator may use a standby storage battery pack access mode to disconnect a fuse and a cable of a current storage battery pack to be detected, and access the standby storage battery pack to serve as a substitute power supply for the current storage battery pack.
Through the process, the standby storage battery pack is connected with the current storage battery pack to be detected, so that the effect of using the standby storage battery pack as a substitute power supply of a communication power supply in the process of detecting the current storage battery pack is achieved, and the problem of power supply service interruption in the process of detecting the current storage battery pack is further solved.
Fig. 5 shows a flow chart of an alternative method for detecting a battery according to an embodiment of the present invention to further describe the method for detecting a battery pack, where fig. 5 simulates discharge detection of the battery pack of the communication power supply 2 in fig. 3, and specifically includes the following steps:
step 1: an operator firstly checks whether the float charging voltages of the two communication power supplies are consistent, and if the difference is large, the float charging voltages are manually modified to the state that the pressure difference is not higher than 0.5V;
step 2: the operator disconnects the fuse of the communication power supply 1;
and step 3: an operator respectively connects the positive pole and the negative pole of a storage battery pack of the communication power supply 1 with a direct current cable in parallel (each of the direct current cables needs to be insulated);
and 4, step 4: the operator closes the fuse of the communication power supply 1;
and 5: the operator disconnects the fuse of the communication power supply 2;
step 6: the operator disconnects the dc cable of the battery pack of the communication power supply 2 and makes insulation;
and 7: an operator accesses a parallel-connected direct-current cable connected with a storage battery pack of the communication power supply 1 into the communication power supply 2;
and 8: the operating personnel observes whether communication power supply monitoring panel has the warning:
and step 9: an operator manually simulates the power failure of the communication power supply 2 and observes the monitoring panel, and the load is normal at the moment;
step 10: the operator simulates the communication power supply 1 to cause the AC input to break down and observes the monitoring panel, and the load is normal at the moment.
Through the process, the method for detecting the storage battery in the embodiment of the invention achieves the aim that the communication power supply still has a substitute power supply in the storage battery detection process, thereby realizing the technical effect of improving the stability of the power supply service in the storage battery detection process, and further solving the technical problem of power supply service interruption in the storage battery detection process in the prior art.
