Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example one
Referring to fig. 1, an implementation flow diagram of an embodiment of a battery detection method is provided, which is detailed as follows:
step S101, determining the actual single battery information of the battery pack.
The actual single battery information refers to actual battery information of each battery in the battery pack including the actual number of battery cells, for example, information such as an actual voltage value, an actual current value, and an actual electric quantity of each battery in the battery pack.
The actual battery section number refers to the actual battery section number of the battery pack, and the first preset battery section number refers to the theoretical battery section number of the battery pack set through the human-computer interface.
The modular UPS used in the market at present can bring more choices to customers in order to match different customer requirements, and the number of the configured battery sections can be from 16 sections to 20 sections, and the range is even wider. However, although the wide-range battery voltage operation brings convenience, if the number of actually configured battery sections is not matched with the number of battery sections set on the human-computer interface, the control parameter points in the charging and discharging process deviate, which easily causes the problem of battery overcharge or battery overdischarge. For example, 16 battery packs are arranged in an actual battery pack, but the human-machine interface is set to be 18 battery packs for operation reasons, the battery is easily overcharged, the battery is damaged, if 20 battery packs are arranged in the actual battery pack, the human-machine interface is set to be 18 battery packs, the battery is certainly not fully charged, the standby power time is insufficient, and meanwhile, when the battery is discharged, the low-voltage protection point of the battery deviates, the overdischarge is caused, and the battery is damaged. In the prior art, the abnormal phenomenon of the battery pack cannot be accurately detected through the total voltage of the battery pack.
Therefore, the embodiment determines whether the battery pack is abnormal or not through the actual information of the single battery, and further can judge whether the battery is in an overcharged state or an overdischarged state or not, protect each battery in the battery pack and prolong the service life of the battery.
In another embodiment, the specific implementation process of acquiring the actual single battery information of the battery pack includes:
and acquiring battery data of a second preset battery section number in the battery pack, and calculating to obtain the actual single battery information according to the battery data and the second preset battery section number.
And the second preset battery section number is less than or equal to the actual battery section number of the battery pack.
The actual single battery information refers to actual battery information of each battery in the battery pack. For example, the battery pack has 20 batteries, and the actual single battery information may be an actual single voltage value, which is 14V, that is, the voltage value of each battery of the 20 batteries in the battery pack is actually 14V.
Specifically, the battery data is obtained by collecting total battery information or single battery information of a second preset battery number in the battery pack. Illustratively, the battery pack includes 20 batteries, and the second preset number of battery sections may be 10, then total battery information (battery data) of 10 batteries in the battery pack is obtained, and the actual single battery information is obtained by dividing the total battery information by 10; or, acquiring battery information (battery data) of each of 10 batteries in the battery pack, adding the battery information of each of the 10 batteries to obtain total battery information of the 10 batteries, and dividing the total battery information of the 10 batteries by 10 to obtain the actual single battery information.
Optionally, the actual single-cell battery information may be an actual single-cell voltage value, an actual single-cell current value, and an actual single-cell electric quantity.
For example, the actual single battery information may be an actual single voltage value. Specifically, the battery pack may include 20 batteries, and the second preset number of battery sections may be 5, battery information of 5 batteries in the battery pack is obtained, a total voltage value of the 5 batteries is 67.5V, and the total voltage value of the 5 batteries is divided by 5, so that an average voltage value of each battery is 13.5V, that is, the actual single-battery voltage value is 13.5V.
It should be understood that the second preset number of battery sections may be 1 section, may be multiple sections, and may be equal to the number of battery sections of the battery pack. The second preset battery number of the embodiment is at least two, so as to ensure the accuracy of the actual single battery information.
Step S102, acquiring actual battery information of the battery pack and a first preset battery section number, wherein the first preset battery section number is a battery section number set by a human-computer interface.
The actual battery information of the battery pack is the battery information of the actual whole battery pack, such as the actual total voltage of the battery pack, the actual total electric quantity of the battery pack, the actual total current that the battery pack can output, and the like.
The first preset battery section number refers to a battery section number configured on the battery pack by the UPS system through a human-computer interface.
And step S103, determining whether the battery pack is abnormal or not according to the actual battery information, the first preset battery section number and the actual single battery information.
For example, whether the battery pack is abnormal or not is determined according to the actual total voltage, the first preset battery section number and the actual single-section voltage; whether the battery pack is abnormal or not can be determined according to the actual total current, the first preset battery section number and the actual single-section current; or determining whether the battery pack is abnormal or not according to the actual total electric quantity, the first preset battery section number and the actual single-section electric quantity, and the like.
In another embodiment, referring to fig. 2, the specific implementation process of determining whether the battery pack is abnormal according to the actual battery information, the first preset battery number and the actual single battery information in step S103 includes:
step S201, theoretical single battery information of the battery pack is determined according to the actual battery information and the first preset battery node number.
Optionally, the theoretical single-cell battery information refers to theoretical battery information of each cell in the battery pack including the first preset number of cells, and may be theoretical single-cell voltage, theoretical single-cell current, theoretical single-cell electric quantity, and the like.
Specifically, the theoretical single-cell voltage of the battery pack may be determined according to the actual total voltage and the first preset number of battery cells; the theoretical single-section current of the battery pack can be determined according to the actual total current and the first preset battery section number; the theoretical single-battery capacity of the battery pack can be determined according to the actual total electric quantity and the first preset battery section number.
In another embodiment, the specific implementation process of determining the theoretical single-cell battery information of the battery pack according to the actual battery information and the first preset number of battery cells in step S201 includes:
wherein the content of the first and second substances,
and for the theoretical single battery information, Vbat1 is the actual battery information, and N is the first preset battery number.
Optionally, the theoretical single-cell voltage of the battery pack is determined according to the actual total voltage and the first preset number of battery cells, that is, the theoretical single-cell voltage of the battery pack can be obtained according to the above formula. Illustratively, the actual total voltage value of the battery pack is 270V, the first preset battery number set by the human-computer interface is 20, and the theoretical single-cell voltage value of the battery pack is 13.5V.
Step S202, judging whether the theoretical single battery information and the actual single battery information meet a first preset condition.
Specifically, by judging the relationship between the theoretical single battery information and the actual single battery information, it can be determined whether the actual battery number of the battery pack conforms to a first preset battery number, and it is further determined whether the battery pack is abnormal.
In another embodiment, the specific implementation process of determining whether the theoretical single battery information and the actual single battery information satisfy the first preset condition in step S202 includes:
and when the Vbat0-Vbat3> V1 or the Vbat3-Vbat0> V1, determining that the actual battery section number of the battery pack does not accord with the first preset battery section number, and determining that the battery pack is abnormal.
Wherein Vbat0 is the theoretical single battery information, Vbat3 is the actual single battery information, and V1 is the first preset condition.
The first preset condition is a return difference value introduced to avoid an error of actual single battery information, namely, whether a difference value between theoretical single battery information and actual single battery information is within an allowable error range is judged, the first preset condition may specifically be an error range (-V1, V1), whether Vbat0-Vbat3 are within the error range (-V1, V1) is judged, if the error range (-V1, V1) is included, the battery pack is not abnormal, and if the error range (-V1, V1) is not included, the battery pack is determined to be abnormal.
And step S203, determining whether the battery pack is abnormal or not according to the judgment result.
In one embodiment, the determining whether the battery pack is abnormal according to the determination result includes:
and determining whether the actual cell number of the battery pack is equal to the first preset cell number according to the judgment result.
And if the actual battery section number of the battery pack is equal to the first preset battery section number, determining that the battery pack is not abnormal.
And if the actual battery section number of the battery pack is not equal to the first preset battery section number, determining that the battery pack is abnormal.
Illustratively, if Vbat0-Vbat3> V1, the actual battery section number of the battery pack is greater than the first preset battery section number, and the battery pack is determined to be abnormal; and if Vbat3-Vbat0> V1, determining that the actual battery section number of the battery pack is smaller than the first preset battery section number, and determining that the battery pack is abnormal. Wherein Vbat0 is the theoretical single battery information, Vbat3 is the actual single battery information, and V1 is the first preset condition.
Specifically, Vbat0-Vbat3> V1, which indicates that the number of first preset battery sections set on the human-computer interface of the UPS system is less than the number of battery sections configured in the actual battery pack, and the battery of the battery pack may be in an over-discharge state, that is, it is determined that the battery pack is abnormal, an alarm is issued, and a manager is notified to increase the number of first preset battery sections set on the human-computer interface of the UPS system; if Vbat3-Vbat0> V1, the situation that the number of the first preset battery sections set on the human-computer interface of the UPS system is larger than the number of the battery sections configured on the actual battery pack, and the battery of the battery pack is possibly in an overcharged state is determined, namely, the battery pack is determined to be abnormal, an alarm is given out, and a manager is informed to reduce the number of the first preset battery sections set on the human-computer interface of the UPS system.
Optionally, in this embodiment, whether the number of battery cells of the battery pack is equal to a first preset number of battery cells set on the human-computer interface is determined by using voltage, that is, whether the number of battery cells of the battery pack is equal to the first preset number of battery cells set on the human-computer interface is determined by using a relationship between actual single-cell voltage and theoretical single-cell voltage, and whether the battery pack is abnormal is determined, so that whether the battery of the battery pack is in an overcharged state or an overdischarged state can be determined, and if the number of battery cells of the battery pack is not equal to the first preset number of battery cells set on the human-computer interface, it is determined that the detected battery pack is abnormal, and a manager is notified to check the number of battery cells of the battery pack or the number of battery cells set on the human-computer interface, so as to protect the battery in time.
For example, whether the theoretical single-link voltage and the actual single-link voltage meet a first preset condition is judged, and whether the battery pack is abnormal is determined according to the judgment result. For example, if the theoretical single-section voltage is 13.5V, the actual single-section voltage is 15V, and the first preset condition is 1V, then Vbat0-Vbat3> V1 indicates that the number of the first preset battery sections set on the human-computer interface of the UPS system is less than the number of the battery sections configured on the actual battery pack, and the battery of the battery pack may be in an overdischarge state, that is, it is determined that the battery pack is abnormal.
Illustratively, the theoretical single-cell voltage is 12.8V, the actual single-cell voltage is 13.5V, and the first preset condition is 0.5V, then Vbat3-Vbat0> V1, which indicates that the number of the first preset battery cells set on the human-computer interface of the UPS system is greater than the number of battery cells configured in the actual battery pack, and the battery of the battery pack may be in an overcharged state, i.e., it is determined that the battery pack is abnormal.
Illustratively, the theoretical single-cell voltage is 13.5V, the actual single-cell voltage is 13.7V, the first preset condition is 0.5V, and the difference between the theoretical single-cell voltage and the actual single-cell voltage is within an error range (-0.5, 0.5) formed by the first preset condition, which indicates that the first preset number of battery cells set on the human-computer interface of the UPS system is equal to the number of battery cells configured in the actual battery pack, i.e., it is determined that there is no abnormality in the battery pack.
The present embodiment does not limit the number of battery cells of the battery pack, that is, does not limit the actual battery information, the actual single battery information, the theoretical single battery information, and the specific numerical value of the first preset condition, and has different battery information according to different battery packs.
It should be understood that, in this embodiment, whether the number of battery cells of the battery pack is equal to the first preset number of battery cells set on the human-computer interface may also be determined according to a relationship between the actual single-cell current and the theoretical single-cell current, and whether the number of battery cells of the battery pack is equal to the first preset number of battery cells set on the human-computer interface may also be determined according to a relationship between the actual single-cell electric quantity and the theoretical single-cell electric quantity.
Optionally, in this embodiment, different alarms may be issued according to different determination results of whether the theoretical single battery information and the actual single battery information satisfy the first preset condition, so as to prompt a worker to check the relevant parameters.
In another embodiment, the method further comprises:
and when the actual battery section number of the battery pack is judged to be larger than the first preset battery section number, increasing a preset single-section uniform charging voltage point, a preset single-section floating charging voltage point, a preset single-section overvoltage protection point and a preset single-section undervoltage protection point of the battery pack.

The method for detecting the battery comprises the steps of determining theoretical single-cell battery information of a battery pack by acquiring actual battery information of the battery pack and the first preset cell number; and then, whether the actual battery section number is consistent with a first preset battery section number set by a human-computer interface of the UPS system or not is determined according to the theoretical single battery information and the actual single battery information, namely whether the battery pack is abnormal or not can be accurately detected by judging whether the actual battery section number is equal to the first preset battery section number set by the human-computer interface of the UPS system or not, whether the battery in the battery pack has an overcharge or overdischarge phenomenon or not can also be determined, the overcharge or overdischarge of the battery is avoided in time, and each battery is better protected.
