Translated fromChinese技术领域technical field
本申请涉及退役动力电池再利用技术领域，尤其涉及一种退役动力电池的短板电池隔离装置和方法。The present application relates to the technical field of reuse of retired power batteries, and in particular, to a short-board battery isolation device and method for retired power batteries.
背景技术Background technique
随着国内电动汽车行业的蓬勃发展，电动汽车所用的动力电池的装机量也逐年上升。截至2018年底，我国的电动汽车保有量已经达到261辆，早起投入市场的动力电池即将迎来退役期，预计到2020年退役动力汽车的规模累计将超过20GWh，隐藏在电动汽车繁华发展表面之下的是动力电池的回收与再利用问题。With the vigorous development of the domestic electric vehicle industry, the installed capacity of power batteries used in electric vehicles has also increased year by year. As of the end of 2018, the number of electric vehicles in my country has reached 261, and the power batteries that have been put into the market early are about to enter the retirement period. The problem is the recovery and reuse of power batteries.
电动汽车对动力电池的性能要求较高，根据QC/T 743-2006《电动汽车用锂离子蓄电池》中“6.2.11循环寿命”规定“蓄电池在20℃±2℃下以1.5I3(A)电流放电，直到放电容量达到额定容量的80％”，当电动汽车内的动力电池容量衰减至标称容量80％以下时，可认为是其循环寿命终止，不适宜继续使用。为了确保电动汽车的动力性能、续驶里程和运行过程中的安全性能，必须对其进行更换，更换下来的电池被称为“退役动力电池”。Electric vehicles have higher performance requirements for power batteries. According to "6.2.11 Cycle Life" in QC/T 743-2006 "Lithium-ion batteries for electric vehicles" The current is discharged until the discharge capacity reaches 80% of the rated capacity. When the capacity of the power battery in the electric vehicle decays to below 80% of the nominal capacity, it can be considered that its cycle life is terminated and it is not suitable for continued use. In order to ensure the power performance, driving range and safety performance of electric vehicles during operation, they must be replaced, and the replaced batteries are called "retired power batteries".
通常从电动汽车上更换下来的退役动力电池，仍具有较高的剩余容量和利用价值，经过筛选和重新配组，在退役动力电池重组集成后，可应用于低速电动车、助力车、直流电源、微电网等场景，也可应用于运行环境相对良好、充放电工况相对温和、对电池性能要求相对较低的储能场合，实现退役动力电池的梯次利用，减缓回收处理的压力。Retired power batteries usually replaced from electric vehicles still have high residual capacity and utilization value. Microgrid and other scenarios can also be applied to energy storage occasions where the operating environment is relatively good, the charging and discharging conditions are relatively mild, and the battery performance requirements are relatively low, realizing the cascade utilization of retired power batteries and reducing the pressure of recycling.
然而，退役动力电池的类型多样、性能参差不齐，且存在较大离散性。另外，在整组电池内通常存在短板电池，这导致退役动力电池在梯次利用中出现可用率低、配组困难、接入不灵活等诸多问题。However, the types of retired power batteries are diverse, their performance is uneven, and there is a large dispersion. In addition, there are usually short-board batteries in the whole group of batteries, which leads to many problems such as low availability, difficult matching, and inflexible access of retired power batteries in the cascade utilization.
退役动力电池内的短板电池，由于性能的下降显著，将会影响整体性能，使整组电池提前退出使用，并有可能存在安全隐患。The short-board batteries in the retired power batteries will affect the overall performance due to the significant decline in performance, causing the entire battery group to be withdrawn from use in advance, and there may be potential safety hazards.
通常，需要通过拆解整组电池的方法，在整组电池中剔除掉短板电池，不仅拆解和重组的工艺复杂，而且整组内的其他电池也可能会受到损伤，留下隐患。对于存在较少短板电池的退役动力电池的处理方法有：将整组电池包以电池模组的形式进行拆解，再以电池模组为单位进行分选和配组，含有短板电池的电池模组被弃用。由于电池模组之间的连接通常采用螺丝等方式来固定，拆解相对简单，工作量低，但是拆解后的电池包整体的利用率较低，经常会出现因为短板电池而弃用较多的情况，容易出现整组电池包的电芯数量不够而无法配组的情况。Usually, it is necessary to remove the short-board batteries in the whole group of batteries by disassembling the whole group of batteries. Not only is the disassembly and reassembly process complicated, but other batteries in the whole group may also be damaged, leaving hidden dangers. The disposal methods for retired power batteries with fewer short-board batteries are: disassemble the entire battery pack in the form of battery modules, and then sort and match the battery modules as a unit. Battery modules are deprecated. Since the connection between the battery modules is usually fixed by means of screws, the disassembly is relatively simple and the workload is low, but the overall utilization rate of the disassembled battery pack is low, and it often occurs that the battery is discarded because of the short board. In many cases, it is prone to the situation that the number of cells in the whole battery pack is not enough and cannot be matched.

Obviously, the described embodiments are only It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
短板电池：动力电池系统是由若干单体电芯(Cell)通过导电连接件(Bus-bar)进行串联或并联而组成。单体电芯(Cell)成组的形式，可以是整个电池包(Pack)或数个电池模组(Module)形式，同组内的电芯在电参数、性能与状态上呈现为较高的一致性。Short board battery: The power battery system is composed of several single cells (Cell) connected in series or in parallel through conductive connectors (Bus-bar). The single cell (Cell) is in the form of a group, which can be in the form of the entire battery pack (Pack) or several battery modules (Module), and the cells in the same group have higher electrical parameters, performance and status. consistency.
由于各电芯在制造工艺或材料的细微差别、在电芯排布中因所在位置不同而带来的运行温度差别、在电池管理(BMS)的采集和均衡的精度及误差的差别，都会导致同组内的个别电芯在电压、容量以及健康度等方面上与其他电芯存在很大的差异。个别电芯的劣化，首先是体现与其他电芯的一致性上的差异，进而逐步蔓延和影响整组电芯的性能和状态，呈现出“木桶效应”。此时该一致性较差的电芯则被称为“短板电池”，退役动力电池内通常含有一定数量的短板电池。当退役动力电池在开展梯次利用时，根据电池模组内各单体电芯的一致性的极差要求，确定短板电池的数量和物理隔离的位置，并对其导电连接件进行分拆隔离与跨接旁路的工艺。假设电池模组内BAT2为短板电池，对该短板电池进行旁路处理，则无需将短板电池从整个电池模组内取出，进而减少拆解环节，提高工作效率，降低再利用成本，同时便于后期维护和作业，更利于规模化应用。Due to the subtle differences in the manufacturing process or materials of each cell, the difference in operating temperature caused by the location of the cells in the arrangement of the cells, and the difference in the accuracy and error of the battery management (BMS) collection and equalization, it will lead to Individual cells in the same group are quite different from other cells in terms of voltage, capacity, and health. The deterioration of individual cells first reflects the difference in consistency with other cells, and then gradually spreads and affects the performance and status of the entire group of cells, showing a "cask effect". At this time, the cells with poor consistency are called "short-board batteries", and retired power batteries usually contain a certain number of short-board batteries. When the retired power battery is used in cascade, according to the requirements of the consistency of each single cell in the battery module, the number of short-board batteries and the location of physical isolation are determined, and the conductive connectors are separated and isolated. Process with jumper bypass. Assuming that BAT2 in the battery module is a short-board battery, and the short-board battery is bypassed, there is no need to remove the short-board battery from the entire battery module, thereby reducing the disassembly process, improving work efficiency, and reducing reuse costs. At the same time, it is convenient for later maintenance and operation, and it is more conducive to large-scale application.
对电池模组内的短板电池在进行旁路跨接处理后，虽然在电气物理连接上被隔离的短板电池已与其它电芯完全脱离，但是其本身仍然可以作为独立个体以静止状态长期存在于整个电池模组内，并受周围环境的影响，电芯电压和温度等特性仍处于未知的状态。若是缺少相应的监管措施，整个电池模组依然存在潜在的安全隐患，因此有必要对电芯的相关特征状态进行实时在线监测管理。After bypassing the short-board battery in the battery module, although the short-board battery isolated on the electrical and physical connection has been completely separated from other cells, it can still be used as an independent individual in a static state for a long time. It exists in the entire battery module and is affected by the surrounding environment, and the characteristics such as cell voltage and temperature are still in an unknown state. If there is a lack of corresponding regulatory measures, the entire battery module still has potential safety hazards, so it is necessary to conduct real-time online monitoring and management of the relevant characteristics of the battery cells.
对已经进行旁路跨接处理的短板电池进行在线监测管理的电路图如图6所示的传统的电池管理BMS的结构示意图以及图7所示的本申请的结构示意图，对于已经隔离的短板电池，为保证电池模组和整个系统的安全稳定运行，需对短板电池进行独立的在线监视与管理，以确保其性能稳定和安全运行，及时发现并避免出现短板电池进一步劣化的情况。The circuit diagram of on-line monitoring and management of the short-board battery that has been bypassed and cross-connected is shown in FIG. 6 , the structural schematic diagram of the traditional battery management BMS and the structural schematic diagram of the present application shown in FIG. 7 . For the isolated short board For batteries, in order to ensure the safe and stable operation of the battery module and the entire system, it is necessary to conduct independent online monitoring and management of short-board batteries to ensure stable performance and safe operation, and to detect and avoid further deterioration of short-board batteries in time.
在传统的电池管理BMS或第三方电池管理BMS中，是将采集线束连接在每个单体电芯的两端，如图8所示的监测信号流向图，由采集线束接入到电池管理BMS装置的采集端子，通过模拟前端AFE进行多通道控制，再进入ADC测量，由MCU采集、分析和后续处理。In the traditional battery management BMS or third-party battery management BMS, the acquisition wiring harness is connected to both ends of each single cell, as shown in the monitoring signal flow diagram shown in Figure 8, from the acquisition wiring harness to the battery management BMS The acquisition terminal of the device performs multi-channel control through the analog front-end AFE, and then enters the ADC measurement, which is collected, analyzed and subsequently processed by the MCU.
而隔离托管监测相对于传统电池管理BMS进行两个方面的改进：Compared with traditional battery management BMS, isolated managed monitoring has two improvements:
一是由于在电池模组的主回路连接上，对短板电池进行了跨接处理，导致原有采集线束无法继续正常使用，如重新加工和安装线束，将费时费力、成本高，因此本申请提出了在传统电池管理BMS的模拟前端AFE前增加“隔离选通配置矩阵”的改进，可以实现对原有采集线束的复用，无须重新加工和安装；First, because the short-board battery is bridged on the main circuit connection of the battery module, the original collection wiring harness cannot continue to be used normally. For example, reprocessing and installation of the wiring harness will be time-consuming, laborious and costly. Therefore, this application The improvement of adding "isolation gating configuration matrix" before the analog front-end AFE of the traditional battery management BMS is proposed, which can realize the reuse of the original acquisition wiring harness without reprocessing and installation;
二是当短板电池被跨接后，短板电池在电池模组内处于分列和孤立的地位，形成了无人监测和管理的局面，并存在一定的潜在故障隐患，出于此考虑因此本申请提出了在传统电池管理BMS的基础上增加独立“托管监视监测电路”的改进，对被跨接的短板电池进行实时监测和管控，实现可知可控的全面管理，同时可以复用原有的数据传输通道，无须另外布线和通信连接。The second is that when the short-board batteries are bridged, the short-board batteries are in a separate and isolated position in the battery module, forming a situation of unmanned monitoring and management, and there are certain potential failure hazards. This application proposes the improvement of adding an independent "hosted monitoring and monitoring circuit" on the basis of the traditional battery management BMS, which can monitor and control the short-board batteries that are connected in real time, realize comprehensive management that is known and controllable, and can reuse the original battery. Some data transmission channels do not require additional wiring and communication connections.
短板电池的在线监测管理需要实时监测短板电池的电芯电压和温度等关键特征参数，为了防止电池过放出现电压过低而劣化加速的情况，还需要预留专门的补电电路如图9。The online monitoring and management of the short-board battery requires real-time monitoring of key characteristic parameters such as the cell voltage and temperature of the short-board battery. In order to prevent the battery from over-discharging, the voltage is too low and the deterioration is accelerated, and a special power supply circuit needs to be reserved as shown in the figure. 9.
隔离托管：动力电池系统，是由若干单体电芯(Cell)通过导电连接件(Bus-bar)进行串联或并联而组成，加速了整组电池的劣化和退役，也影响退役动力电池再利用的使用，制约后续梯次利用的发展。Isolation and trusteeship: The power battery system is composed of several single cells (Cell) connected in series or in parallel through conductive connectors (Bus-bar), which accelerates the deterioration and retirement of the entire battery group, and also affects the reuse of retired power batteries. The use of it restricts the development of subsequent echelon utilization.
通常导电连接件(Bus-bar)固定在电芯极柱的设计位置，起到连接、固定和安全防护等作用，拆解起来难度高、工作量大。根据整组电池中短板电池的分布情况，采用“定点清除”的方式，在不需要对整组电池中进行拆解的情况下，仅对已存在的短板电池进行切割拆解，再通过铜排、电缆等导电连接件进行跨接和旁路，实现对短板电池的隔离旁路。对于已隔离的短板电池，保留在整组电池中而不需要拆除，保留整组电池的原线束，采用独立通道的电压、电流、温度等电参数采集，实现对已隔离短板电池的托管和监视，保障其处于可知可控的状态，确保经重组后退役动力电池的安全稳定运行。隔离托管仅针对整组电池内的短板电池，与整组电池中的其他电芯采用不同的电池管理硬件和策略。Usually, the conductive connector (Bus-bar) is fixed at the design position of the cell pole, which plays the role of connection, fixation and safety protection. It is difficult to disassemble and the workload is heavy. According to the distribution of the short-board batteries in the whole group of batteries, the method of "fixed-point removal" is adopted, and only the existing short-board batteries are cut and disassembled without the need to disassemble the entire group of batteries. The conductive connectors such as copper bars and cables are bridged and bypassed to achieve isolation and bypass of short-board batteries. For the isolated short-board batteries, keep them in the whole group of batteries without removing them, keep the original wiring harness of the whole group of batteries, and use independent channels to collect electrical parameters such as voltage, current, temperature, etc., to realize the custody of the isolated short-board batteries And monitoring, to ensure that it is in a knowable and controllable state, to ensure the safe and stable operation of the retired power battery after reorganization. Isolated hosting is only for short-board batteries in the entire battery pack, and uses different battery management hardware and strategies from other cells in the entire battery pack.
对于已隔离的短板电池，保留在整组电池中无须拆出，保留整组电池的原线束，采用独立通道对已隔离的短板电池的电压和温度等电参数进行采集，用以实现对已隔离的短板电池的托管和监视，以保障其处于可知可控的状态，以确保经重组后退役动力电池的安全稳定运行。For the isolated short-board battery, keep it in the whole battery group without removing it, keep the original wiring harness of the whole group of batteries, and use an independent channel to collect the voltage and temperature and other electrical parameters of the isolated short-board battery. Hosting and monitoring of isolated short-board batteries to ensure that they are in a knowable and controllable state to ensure the safe and stable operation of retired power batteries after reorganization.
而在传统的电池管理BMS中，各电芯间依次串联，其首尾两端引出线分别串联保险丝F，而后进入专用AFE的采集芯片中进行电压采样，采集方式一般为8通道、12通道、16通道电芯的数据采集。如附图10所示的传统的电池管理BMS的电压采集示意图。In the traditional battery management BMS, the cells are connected in series in sequence, and the lead wires at the head and tail ends are connected in series with the fuse F respectively, and then enter the collection chip of the dedicated AFE for voltage sampling. The collection methods are generally 8 channels, 12 channels, 16 channels. Data acquisition of channel cells. As shown in FIG. 10 , a schematic diagram of voltage acquisition of a conventional battery management BMS is shown.
对于存在有短板电池的电池模组，短板电池被旁路隔离后，若是采用传统的电池管理BMS和原有线束，由于短板电池的正负极仍与采集芯片的某个通道相连，会造成采集芯片的工作异常，而无法进行对正常电芯的电压采集。另外，对于已经隔离的短板电池，如果需要进行状态监测的话则需要增加新的采集线束。因此为了避免这些问题，本申请根据电池模组内对于短板电池的处理，除了在电池模组内对短板电池进行旁路跨接外，对电池的管理系统的硬件电路中也进行了优化设计，通过隔离选通矩阵，无需改变原有的线束，通过初始化配置，就可以灵活的实现对不同数量不同规格的电池模组的兼容，对于电池模组的改造效率以及经济性均较高。For a battery module with a short-board battery, after the short-board battery is isolated by bypass, if the traditional battery management BMS and the original wiring harness are used, since the positive and negative electrodes of the short-board battery are still connected to a certain channel of the acquisition chip, It will cause the acquisition chip to work abnormally, and the voltage acquisition of the normal cell cannot be performed. In addition, for the isolated short-board batteries, if condition monitoring is required, a new collection harness needs to be added. Therefore, in order to avoid these problems, according to the treatment of short-board batteries in the battery module, in addition to bypassing the short-board batteries in the battery module, the hardware circuit of the battery management system is also optimized. Design, by isolating the gating matrix, without changing the original wiring harness, by initializing the configuration, it is possible to flexibly achieve compatibility with different numbers of battery modules of different specifications, and the transformation efficiency and economy of battery modules are high.
本申请实施例提供了一种退役动力电池的短板电池隔离装置和方法，解决了现有技术中由于电池模组之间的连接通常采用螺丝等方式来固定，拆解相对简单，工作量低，但是拆解后的电池包整体的利用率较低，经常会出现因为短板电池而弃用较多的情况，容易出现整组电池包的电芯数量不够而无法配组的情况的技术问题。The embodiment of the present application provides a short-board battery isolation device and method for a retired power battery, which solves the problem that in the prior art, since the connection between battery modules is usually fixed by means of screws, the disassembly is relatively simple, and the workload is low. , but the overall utilization rate of the disassembled battery pack is low, and it often occurs that more batteries are discarded because of short-board batteries, and it is prone to technical problems that the number of cells in the entire battery pack is not enough to be matched. .

本申请第一方面提供了一种退役动力电池的短板电池隔离装置，包括：A first aspect of the present application provides a short-board battery isolation device for a retired power battery, including:
电池模组，电池模组包括至少一个短板电池，短板电池在经过旁路跨接后接入隔离选通配置矩阵；A battery module, the battery module includes at least one short-board battery, and the short-board battery is connected to the isolation gating configuration matrix after being bypassed;
隔离选通配置矩阵在短板电池的两端均串接保险，并预留短接片位置，用于安装短接片；The isolation gating configuration matrix is connected in series with the insurance at both ends of the short-board battery, and the shorting piece position is reserved for installing the shorting piece;

需要说明的是，如附图4所示的电路图，在每节电池的两端均引出线间预留短接片的位置，组成隔离选通配置矩阵。在电池模组的正常工作状态下，可以用专用AFE芯片依次采集电池模组的所有的电池电压，比如电池1#的电压为Uab，电池2#的电压为Ubc，以此类推。当电池2#需要被托管时，可以去除保险丝F1，安装短接片F2A。此时，Uac＝Uab为电池1#的电压，Ubc＝0，则表明专用AFE芯片的数据可以正常采集。It should be noted that, as shown in the circuit diagram in FIG. 4 , the positions of shorting tabs are reserved between the lead wires at both ends of each battery to form an isolation gating configuration matrix. In the normal working state of the battery module, the dedicated AFE chip can be used to sequentially collect all the battery voltages of the battery module, for example, the voltage of

进一步地，托管监测电路还包括差分放大电路，用于连接多个选通电路。Further, the managed monitoring circuit further includes a differential amplifier circuit for connecting a plurality of gating circuits.
需要说明的是，由于整簇电池组的电压较高，短板电池在簇内的分布位置未知，如果直接将短板电池的正负极柱直接接入ADC中，由于短板电池产生的极高的共模电压会造成ADC的损坏，甚至导致安全事故。如图11所示，通过短板电池的选通电路可以有效隔离高共模电压的影响，使得进入后级采集电路的信号在ADC的可接受范围之内。It should be noted that due to the high voltage of the entire cluster of batteries, the distribution position of the short-board batteries in the cluster is unknown. If the positive and negative columns of the short-board batteries are directly connected to the ADC, the polar High common-mode voltage can cause damage to the ADC and even lead to safety incidents. As shown in Figure 11, the gating circuit of the short-board battery can effectively isolate the influence of high common-mode voltage, so that the signal entering the subsequent acquisition circuit is within the acceptable range of the ADC.

By configuring the battery module, data exchange and status monitoring can be realized.
进一步地，托管监测电路设置于子板上，子板插接于安装有电池模组的采集线束的通用化母板。Further, the hosting monitoring circuit is arranged on the sub-board, and the sub-board is inserted into the generalized motherboard on which the collection wiring harness of the battery module is installed.
需要说明的是，托管监测电路的整个电路可采用独立板卡的方式，以子母板形式内嵌于传统电池管理BMS内。由于改造是在电池管理单元内进行，不占用设备外空间和多余线束，因此实施难度低、经济性好。It should be noted that the entire circuit hosting the monitoring circuit can be embedded in the traditional battery management BMS in the form of a sub-motherboard in the form of an independent board. Because the transformation is carried out in the battery management unit, it does not occupy the space outside the equipment and redundant wiring harnesses, so the implementation difficulty is low and the economy is good.
另外，此托管监测电路也可独立为单独外置单元(外置隔离托管采集装置)，与第三方电池管理系统串联配合，兼容原有的BMS与电池模组连接线束，仅需增加一条隔离托管采集板与BMS连接线束，具备较好的灵活性与适用性。In addition, this custody monitoring circuit can also be an independent external unit (external isolated custody acquisition device), which is connected in series with a third-party battery management system, compatible with the original BMS and battery module connection harnesses, only need to add an isolated custody The wiring harness connecting the acquisition board and the BMS has better flexibility and applicability.

需要说明的是，本申请实施例提供的退役动力电池的短板电池隔离方法，对于退役动力电池内的短板电池处理分为隔离旁路和托管监视两个阶段：首先是对整组电池中的短板电池进行隔离旁路：先统计整组电池中的短板电池的分布数据，以图3所示的隔离旁路的电路图为例，以图中的2#电芯为短板电池为例，A点为1#电芯的负极，B点为2#电芯的正极，A’点为1#电芯的负极(或者是2#电芯的正极)的采集线束的接入位置。在1#电芯与2#电芯的A与A’的区间内，选择合适的加工位置进行导电连接件的切割和拆解操作。再根据分布数据和采集线束的接入位置，确定跨接电缆或者跨接铜排的载流量和布局走向，将A点和C电进行跨接连接，以此实现对短板电池(即图3中的2#电芯)的跨接旁路隔离。对于已隔离的所有的短板电池，可以将它们继续留在整组电池中无需拆解移出，其他的电芯的主回路的电连接也可以得到相应的保留，各个电芯的采集线束均维持不变。It should be noted that, the short-board battery isolation method for retired power batteries provided by the embodiments of the present application, for the short-board battery processing in the retired power battery, is divided into two stages: isolation bypass and custody monitoring: firstly, for the entire battery group of batteries. Isolation bypass for the short-board batteries: first count the distribution data of the short-board batteries in the whole group of batteries, take the circuit diagram of the isolation bypass shown in Figure 3 as an example, and take the 2# cell as the short-board battery in the figure. For example, point A is the negative pole of the 1# cell, point B is the positive pole of the 2# cell, and point A' is the connection position of the collection harness of the negative pole of the 1# cell (or the positive pole of the 2# cell). In the interval between A and A' of the 1# cell and the 2# cell, select the appropriate processing position to perform the cutting and dismantling operations of the conductive connector. Then according to the distribution data and the access position of the collected wiring harness, determine the current carrying capacity and layout direction of the jumper cable or the jumper copper bar, and connect the point A and the C electricity to jumper, so as to realize the short board battery (ie Figure 3). 2# cell in the 2# cell) of the bypass bypass isolation. For all the isolated short-board batteries, they can be left in the entire battery group without disassembling and removing them. The electrical connections of the main circuits of other cells can also be retained accordingly, and the collection harnesses of each cell are maintained. constant.
对于所有已经隔离的短板电池进行托管监视的步骤有：首先统计整组电池中所有已隔离的短板电池的分布数据。以图4所示的隔离选通配置矩阵的电路图为例，图中以2#电芯为短板电池为例，经各类旁路处理后，通过隔离选通配置矩阵进行配置，将F1位置处去除保险F1，并在F1’位置处安装保险F1’，用以短接2#电芯的原采集点。此时，Uab＝Uac，即为1#电芯的实际电压，而Ubc＝0，即表示2#电芯未被采集，专用前端芯片AFE未出现浮空，Ucd＝Ubd，即为实际3#的电芯电压，全部的电池数据均可以被正常采集。在每一个隔离选通配置矩阵内，每节电芯均连接托管监视电路。托管监视电路可以由图11所示的电路图中的选通电路、差分放大电路、ADC采集电路、微处理器和通信接口组成，这些电路均由微处理器控制，根据隔离短板电池的数量和接线来控制选通电路，保证仅有1路已隔离的短板电池接入差分放大电路中。通过收集到的被测信号经过AD采集以及微处理器来分析其性能和状态，经过通讯接口上传至后台，所采集的信号可以用来在线监测短板电池的状态，并进行状态评估。The steps of conducting managed monitoring for all isolated short-board batteries are as follows: First, count the distribution data of all isolated short-board batteries in the entire battery group. Take the circuit diagram of the isolation gating configuration matrix shown in Figure 4 as an example. In the figure, the 2# cell is used as an example of a short-board battery. After various bypass treatments, the configuration is performed through the isolation gating configuration matrix, and the F1 position is set. Remove the fuse F1 at the place, and install the fuse F1' at the position of F1' to short-circuit the original collection point of the 2# cell. At this time, Uab=Uac, which is the actual voltage of the 1# cell, and Ubc=0, which means that the 2# cell is not collected, and the dedicated front-end chip AFE does not float, Ucd=Ubd, which is the actual 3# If the cell voltage is high, all battery data can be collected normally. Within each isolated gating configuration matrix, each cell is connected to a managed monitoring circuit. The managed monitoring circuit can be composed of a gating circuit, a differential amplifier circuit, an ADC acquisition circuit, a microprocessor and a communication interface in the circuit diagram shown in Figure 11. These circuits are all controlled by the microprocessor, according to the number of isolated short-board batteries and Wiring is used to control the gating circuit to ensure that only one isolated short-board battery is connected to the differential amplifier circuit. The collected measured signal is collected by AD and microprocessor to analyze its performance and status, and uploaded to the background through the communication interface. The collected signal can be used to monitor the status of the short-board battery online and perform status evaluation.
