After a battery pack in a power battery or an energy storage battery is charged and discharged for a period of time, each single battery forming the battery pack has certain capacity difference. If these differences are not corrected in time, the overall charge-discharge cycling capability of the battery pack may be rapidly degraded and may lead to a safety hazard of the battery pack. Practice has shown that the cycle life of a battery pack, when grouped in series, is typically reduced by 30-50% relative to the nominal cycle life of each of the individual cells comprising the battery pack. In response to this phenomenon, it is common in the industry to perform online local charging and discharging of individual cells by a technique called cell balancing (or balancing) to maintain the capacity consistency of the cells inside the battery pack.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a flowchart of a monitoring method in a battery maintenance process according to an embodiment. The monitoring method (hereinafter, referred to as a monitoring method) is used for monitoring the process of maintaining the battery pack by the battery maintenance instrument. The method comprises the following steps:
step S110, obtaining battery voltage information and equalization current information of at least some single batteries in the battery pack within a preset time.
It is understood that the battery voltage information includes battery voltage data and a battery identifier. The equalization current information includes equalization current data and a battery identifier. The battery identifier is used for uniquely characterizing the corresponding single battery, that is, the battery identifier in the battery voltage information can be used for knowing to which single battery the battery voltage data in the battery voltage information belongs. The battery voltage data and the equalization current data may be detected by respective sensors, such as a voltage sensor for detecting the battery voltage and then a current sensor for detecting the equalization current. The number of the monitored single batteries can be customized according to needs, for example, a certain single battery can be specially monitored, and all the single batteries can also be monitored. In the present embodiment, the battery voltage information and the equalization current information of all the single batteries are acquired, so that the effectiveness and safety of the whole equalization process can be evaluated from the global perspective. The preset time may be the whole maintenance process or a certain stage of the maintenance process. That is, the acquired battery voltage information and the acquired balancing current information are voltage information and current information detected in the whole maintenance process.
In an embodiment, to ensure that the system can automatically recognize and acquire data, the corresponding battery voltage information further includes a voltage identifier, and the balancing current information further includes a current identifier. The processor or the like can determine whether the corresponding information belongs to the battery voltage information or the equalizing current information from the acquired information.
In an embodiment, the monitoring method may be real-time monitoring, or monitoring after the maintenance is completed, which may also be referred to as post-monitoring. When the monitoring method is real-time monitoring, battery voltage information and balance current information generated in real time can be acquired. When the monitoring method is post monitoring, all the battery voltage information and the balance current information in the preset time can be read from the memory.
Step S120, respectively displaying the battery voltage information of each single battery within a preset time by using a voltage-time curve and the equalization current information by using a current-time curve, and independently displaying the equalization current information and the battery voltage information, which include the same battery identifier, in groups.
In this embodiment, the display processes of the current-time curve and the voltage-time curve may be displayed in a time axis continuous tracking mode (similar to an oscilloscope), or may be displayed in a statistical playback mode. And, the displayed current-time and voltage-time curves form a synchronous raster pattern. The raster pattern is also called a bitmap, a dot-matrix pattern, or a pixel pattern, and simply, is a pattern in which the minimum unit is formed of pixels. In this embodiment, the voltage-time curve and the current-time curve are displayed by using the same model, for example, both are displayed by using a time axis continuous tracking mode, and there is no overlapping area between the voltage-time curve and the current-time curve, so that the voltage and the equalizing current of the single battery can be clearly monitored.
In this embodiment, in the display process, the equalization current information and the battery voltage information including the same battery identifier are grouped and then independently displayed according to the group, that is, the equalization current information and the battery voltage information of the same battery cell are displayed in groups, and the information between different battery cells is independently displayed. The fact that the information of different single batteries is displayed independently means that overlapping areas do not exist in respective curves, so that the states of the single batteries are conveniently monitored, and the effectiveness and the safety of an equalization algorithm in the equalization process can be analyzed from the global perspective.
According to the monitoring method for the battery maintenance process, the battery voltage information and the balancing current information of at least the single batteries in the maintenance process are independently displayed in a group in a curve form, so that an intuitive data view is formed, the state change of each battery can be accurately reflected, the change condition of each single battery in the current state can be monitored, and the effectiveness and the safety of a balancing algorithm in the balancing process can be intuitively analyzed. In this embodiment, all the single batteries are monitored, so that an overall data view can be obtained, and the effectiveness and the safety of an equalization algorithm in an equalization process can be analyzed from a global perspective. The monitoring method can be used as a man-machine interaction type empirical data analysis method and can be used for assisting the development of an intelligent system control strategy.
In one embodiment, the voltage-time curve and the current-time curve may be displayed in different colors for easy viewing.
In one embodiment, the step of grouping and independently displaying the equalization current information and the battery voltage information containing the same battery identifier in step S120 is to display the battery voltage information and the equalization current information containing the same battery identifier in the display area in a vertically adjacent manner without overlapping each other, and the two have independent display baselines, as shown in fig. 2. That is, the cell voltage information and the equalization current information of the same single cell are arranged vertically adjacent to each other in the display area. In fig. 2, V represents a voltage time curve of the unit cell, and S represents a current time curve of the unit cell. 001-0012 represents a battery identifier. For example, V009 represents a voltage time curve of the unit cell having the battery identifier 009, and S009 represents a current time curve of the unit cell having the battery identifier 009. The two data messages belong to the same single battery and are longitudinally and adjacently arranged in the display area. And, the battery and the equalization current information each have mutually independent baselines. Horizontal lines in fig. 2 each indicate a corresponding voltage baseline and an equilibrium current baseline, and vertical lines in the vertical direction are vertical scales. The voltage corresponding to the voltage baseline refers to the voltage of the corresponding single battery in a normal state, namely the voltage when the single battery is not balanced or is not influenced by the balanced current of other single batteries, and the voltage represented by the baseline is the voltage value marked on the left side. The equilibrium current baseline is 0. Constant current equalization is usually used in the active equalization process, so the whole current-time curve can be displayed in the form of a baseline plus a rectangle, as shown in fig. 2. Where a rectangle above the baseline represents charge equalization and a rectangle below the baseline represents discharge equalization. The length of the rectangle represents the equalization duration, and the height of the rectangle represents the equalization current, so that a user can intuitively obtain the condition of the whole equalization process. Moreover, by displaying the voltage time curve and the current time curve of each single battery, the influence on other batteries in the group in the equalization process can be intuitively reflected, because as can be obviously seen from fig. 2, the battery voltage jump is not performed only on the battery with equalization charging or equalization discharging, but part of the other battery voltages can also change along with the change. The monitoring method can intuitively show the change condition of the incoming call battery pack. A conventional data table is shown in fig. 3. In FIG. 3, CV represents the battery voltage, and 001 to 006 represent the battery identifiers of the different cells, respectively. Obviously, the data in fig. 3 is not intuitive enough, and is not easy to mine the potential relationship between data, and cannot be used to evaluate the equalization effectiveness and security of the equalization process.
In one embodiment, the battery packs may be multiple, that is, the battery maintenance instrument simultaneously maintains multiple battery packs. At this time, the acquired battery voltage information and the acquired equalization current information both include a group identifier of the single battery in the battery pack. The monitoring method also can intensively display the battery voltage information and the equalizing current information of the single batteries containing the same group identifier, namely, the battery voltage information and the equalizing current information of the single batteries in the same group of battery pack are displayed in the same display area, and the battery voltage information and the equalizing current information of the single batteries in other groups are displayed in the other display area in the longitudinal direction. Through the grouping display of the battery pack, a user can conveniently monitor the equalization process of the whole battery pack, and the effectiveness and the safety of an equalization algorithm in the equalization process are analyzed from the perspective of the whole situation.
In an embodiment, the method further includes the steps as described in fig. 4, specifically including:
step S210, obtaining preset characteristic waveforms on each voltage-time curve and/or each current-time curve.
The preset signature may be user-defined. In the present embodiment, a preset characteristic waveform of the voltage-time curve is obtained. The predetermined characteristic waveform is a waveform in which a voltage jump exists. Usually, during the charging/equalizing charge-discharge phase, the corresponding battery voltage will jump, and other battery voltages affected by the equalization may also jump. In other embodiments, the preset specific waveform on the current-time curve may be obtained, or the preset specific waveforms on the current-time curve and the voltage-time curve may be obtained simultaneously. The time when the specific waveform occurs, that is, the time of the transition, is obtained while the preset specific waveform is obtained.
In step S220, the curves having the preset characteristic waveform at the same time are collectively displayed.
In the display process, the voltage time curve and the current time curve of the same single battery are displayed in a group mode, so that the characteristic of group display of the voltage time curve and the current time curve is also reserved in the centralized display process. The method has the advantages that all curves with the same preset characteristic waveform at the same moment are displayed in a concentrated mode, namely, the voltage time curves and the current time curves of all the single batteries with the same or similar jump laws are displayed in a concentrated mode, and therefore mutual influence relations among the single batteries can be monitored visually.
The monitoring method can adjust the longitudinal arrangement sequence among the single batteries in the display process, and is convenient for observing data of a group of related batteries.
Step S210 and step S220 may be performed after the entire display in step S120 is completed, or may be performed during the display process in step S120, that is, the display state is dynamically adjusted according to the acquired preset specific waveform. By capturing the preset characteristic waveform, the combined information of the battery state change can be automatically acquired, such as the mutual charging and discharging between adjacent monomers or the mutual charging and discharging between non-adjacent monomers, or the mutual charging and discharging between a single battery and one group in the battery pack, and the like.
In an embodiment, the monitoring method further includes the steps as included in fig. 5, which specifically includes:
in step S310, a display enlargement instruction is acquired.
A display zoom instruction is typically issued by a user to command at least a portion of the display area to be displayed in zoom. The acquired display magnification instruction will contain information of the target object and the magnification ratio. The magnification scale may be system default or user-defined. The target object is at least one of a voltage time curve or a current time curve. That is, when the system configures a corresponding display area for each curve, the target object is a curve corresponding to the display area, such as a voltage-time curve or a current-time curve. When the system is configured with a corresponding display area for the combination of the current-time curve and the voltage-time curve of each cell, then the target object should include the current-time curve and the voltage-time curve within that display area. Because each battery voltage information and balanced current information of at least part of the single batteries can be displayed in groups in the whole monitoring process, the display area occupied by each single battery is small, and the user can not conveniently view the information in detail. At the moment, the user can realize the amplification display of the target object by sending a display amplification instruction, so that the user can conveniently check the target object.
Step S320, performing an enlargement process on the target object according to the display enlargement instruction.
As described above, the target object can be known when the display enlargement instruction is acquired, and the enlargement processing can be performed on the target object. For example, the system may set the display amplification instruction to be sent by double-clicking a certain display area and set the amplification scale, and then double-clicking a voltage time curve or a current time curve to be amplified may amplify the curve in the display area according to the preset amplification scale. The scale of amplification of the curve without amplification is assumed to be 0 by default.
In another embodiment, step S310 may be implemented by the following steps, as shown in fig. 6. The method specifically comprises the following steps:
in step S410, position information of the selected area is acquired.
The selected area can be selected by the user through a single click or a double click and the like. For example, the user may select a display area by double-clicking on that area. The position information of the selected area is typically position information of the selected area in a longitudinal direction.
In step S420, the display area to which the position information belongs is determined.
In this embodiment, before step S310 is executed, a step of configuring each voltage time curve and each current time curve with a certain display area is further included. Therefore, when the user clicks a certain area in the display area as the selected area, the display area to which the selected area belongs, for example, the display area corresponding to the battery voltage information of a certain single battery, can be determined according to the position information of the selected area.
And step 430, identifying the curve in the corresponding display area as a target object.
After the display area to which the selected area belongs is determined, the curve in the display area is identified as the target object. For example, when the battery voltage information of a certain single battery is determined as the previous selected area, the voltage-time curve of the single battery is taken as a target object, and each pair of the target objects is amplified.
The monitoring method can amplify the display of the display area according to the display amplification instruction sent by the user, so that the user can conveniently check a certain curve.
In an embodiment, the monitoring method may further include the steps shown in fig. 7, specifically including:
in step S510, the type of the currently moved scale is acquired.
The types of scales may include horizontal scales and vertical marks. The initial position of the vertical scale may be set at the start or end of the time axis. In an embodiment, the position of the vertical scale may also be placed at other positions, such as the middle region. At this time, the vertical scale is displayed in a special line type or color, for example, the vertical scale is a dotted line. The horizontal scale and the vertical scale are vertically arranged. Wherein, the horizontal scale can be one or a plurality of. When the horizontal scale is a strip, it may be arranged at the bottom, top or in the middle. When the horizontal scales are multiple, a corresponding horizontal scale is set for each curve. Specifically, the horizontal scale and the baseline may be at the same horizontal position, that is, when measuring parameters at a certain time in different battery packs, the corresponding horizontal scale needs to be moved for measurement.
Therefore, when the type of the moved scale is a vertical scale, step S520 is performed, and when the type of the scale is a horizontal scale, step S530 is performed.
In step S520, time information corresponding to the position of the moved scale is acquired and displayed.
When the movable scale is a vertical scale, only the time information corresponding to the position of the moved scale needs to be determined. In one embodiment, the time of day information is displayed directly adjacent to the scale, such as to the right of the scale.
Step S530, acquiring a display area to which the moved scale belongs, and determining and displaying corresponding parameter information according to the position of the moved scale in the display area.
When the moving scale is a horizontal scale, it is necessary to determine a display area to which the moved position belongs. In particular, each voltage-time curve and each current-time curve configures a determined display area. Therefore, the corresponding display area can be determined according to the position of the horizontal ruler, and the corresponding parameter information can be determined according to the position of the horizontal ruler in the display area. For example, when the display area is a voltage-time curve of a certain single battery, the measurement parameter information corresponding to the moved scale can be determined and displayed according to the position of the scale in the display area of the voltage-time curve. In an embodiment, the measurement values, i.e. the corresponding parameter information, may be determined from the relative position of the scale with respect to a baseline within the display area. The parameter information may be voltage information or equalization current information.
Through setting up horizontal scale and vertical scale that can be mobilizable, can realize measuring on the picture, convenient measuring goes on. In one embodiment, the horizontal scale movement process may be performed in an enlarged view.
In an embodiment, the monitoring method further includes the steps in the embodiment shown in fig. 8:
step S610, a selected area is acquired.
The selected area can be selected by the user through a single click or a double click and the like. For example, the user may select a display area by double-clicking on that area. The position information of the selected area is typically position information of the selected area in a longitudinal direction.
Step S620, obtains the magnification ratio of each curve in the selected area.
Since the user can perform the amplification operation on each curve, it is necessary to further determine whether the amplification ratios of the curves are consistent, that is, to execute step S630.
In step S630, it is determined whether the magnification ratios of the respective curves in the selected area are the same.
If not, executing step S640, otherwise executing step S650.
In step S640, the amplification ratio of each curve is adjusted to a preset amplification ratio.
The preset magnification ratio may be set by default by the system or customized by the user, for example, the preset magnification ratio is set to 0, i.e., the display is not magnified. Only by adjusting the magnification ratio of each curve to be the same, the curves of the same type can be overlapped and displayed based on the same base line for rapid comparison. Step S650 is performed after step S640 is performed.
Step S650, overlapping and displaying each voltage time curve in the selected area based on the same display baseline, and overlapping and displaying each current time curve based on the same display baseline.
The voltage-time curves are overlapped and displayed based on the same display baseline, the current-time curves are overlapped and displayed based on the same display baseline, and the current-time curves and the voltage-time curves are independent from each other and have no overlapped area. Through overlapping the same type of curves and displaying, the rapid comparison among different single batteries can be realized, and an integral change trend can be known.
An embodiment of the present invention further provides a monitoring system for a battery maintenance process, and the monitoring method in the foregoing embodiment may be implemented by the monitoring system. The monitoring system is used for monitoring the maintenance process of the battery maintenance instrument to the battery pack.
