Description

鋰離子電池全方位安全監控系統 Lithium-ion battery comprehensive safety monitoring system

本創作係有關於一種電池成組工藝和電子技術製造領域，尤指一種提供鋰離子電池全方位安全監控系統。 This creation is about a battery assembly process and electronic technology manufacturing field, especially a comprehensive safety monitoring system for lithium ion batteries.

首先，在新能源動力電源或儲能後備電源領域中，鋰離子電池模組結構是重要的核心部件，特別是在某些領域中(比如：純電動汽車領域)，鋰離子電池作為唯一的動力源而尤為重要，因此，鋰離子電池有效的模組結構和全方位的電池健康管理(HBMS)，可以從根本上提高動力電源或儲能後備電源的續航里程和使用壽命。 First of all, in the field of new energy power or energy storage backup power, lithium-ion battery module structure is an important core component, especially in some fields (such as pure electric vehicles), lithium-ion battery as the only power The source is especially important. Therefore, the effective module structure of the lithium-ion battery and the comprehensive battery health management (HBMS) can fundamentally improve the cruising range and service life of the power source or the energy storage backup power source.

其次，電池模組結構成組方式可以分為兩種：第一種為先並聯後串連的模組方式，根據整車需要鋰離子電池組的容量和電壓，電芯先進行並聯，再進行串聯，電芯並聯後由於內阻(包括模組過程中導體內阻)的差異、散熱不均等因素都會影響並聯後電池迴圈壽命，並聯中的某個單位電池短路時，將造成該並聯電路中的電流非常大，容易引發電池燃燒或***的危險。當然這種危險已通過加熔絲的保護技術避免了。第二種為先串聯後並聯的模組方式，根據整組電池的容量，先進行串聯，比如整組容量的1/3，最後再進行並聯，這樣做的目的就是降低大容量電池組故障概率，這種模組方式對管理系統提出了較高的要求。很多情況下，整組電池的停止充電或停止放電往往是串聯回路中個別電池處於弱勢造成。 Secondly, the battery module structure can be divided into two groups: the first one is a module mode in which the first and second parallels are connected in series. According to the capacity and voltage of the lithium ion battery pack required for the whole vehicle, the batteries are first connected in parallel, and then In series, after the battery cells are connected in parallel, the internal resistance (including the internal resistance of the conductor in the module process), uneven heat dissipation and other factors will affect the battery life after parallel connection. When a unit cell in parallel is short-circuited, the parallel circuit will be caused. The current in it is very large and can easily cause the battery to burn or explode. Of course this danger has been avoided by the addition of fuse protection technology. The second type is the module mode of series connection and parallel connection. According to the capacity of the whole battery, the series is first connected, for example, 1/3 of the whole group capacity, and finally parallel connection. The purpose of this is to reduce the probability of failure of the large capacity battery pack. This modular approach puts higher demands on the management system. In many cases, the stop or stop of the entire battery is often caused by a weak battery in the series circuit.

由此可見，凡使用串聯形式的鋰動力電池(或任何其它類型電池)、以及大容量超級電容為動力或輔助動力的場合，在電能的補充或電能釋放過程中，對串聯儲能元件中的任一單體儲能器件實行獨立均衡控制是極其必要的，也是新能源應用領域必須解決的主要技術之一。 It can be seen that where a lithium-ion battery (or any other type of battery) in series and a large-capacity supercapacitor are used for power or auxiliary power, in the process of supplementing or discharging electric energy, in the series energy storage element It is extremely necessary to implement independent equalization control for any single energy storage device, and it is also one of the main technologies that must be solved in the field of new energy applications.

再次，不論哪種動力電源的模組結構方式，都需要對電池的運行狀態進行全方位監控，傳統的電池管理系統(Battery Management System，BMS)對電池很難做到全方位監控，同時電池的模組結構也制約動力電源的全方位監控，這是新能源動力電源應用領域的難點之一。 Thirdly, no matter which kind of power supply module structure, it is necessary to monitor the operating state of the battery. The traditional battery management system (BMS) is difficult to monitor the battery in all directions, while the battery The module structure also restricts the all-round monitoring of the power supply, which is one of the difficulties in the application field of new energy power supply.

爰此，為有效解決上述之問題，本創作之主要目的在於提供一種可大幅提高系統安全性之鋰離子電池全方位安全監控系統。 Therefore, in order to effectively solve the above problems, the main purpose of this creation is to provide a comprehensive safety monitoring system for lithium ion batteries that can greatly improve the safety of the system.

本創作之次要目的，在於提供一種於放電時仍具有持續供電能力以增加續駛里程之鋰離子電池全方位安全監控系統。 The secondary purpose of this creation is to provide an all-round safety monitoring system for lithium-ion batteries that still has continuous power supply capability during discharge to increase driving range.

本創作之次要目的，在於提供一種大幅增加鋰離子電池之充電容量之鋰離子電池全方位安全監控系統。 The second objective of this creation is to provide a comprehensive safety monitoring system for lithium-ion batteries that greatly increases the charging capacity of lithium-ion batteries.

After the contactor between the groups is closed, the relay is disconnected, thereby completing the establishment of the high-voltage system, which is a series structure of a lithium-ion battery comprehensive safety monitoring system, when a dangerous environment is encountered, such as a battery module water inlet, a car accident In such an environment, the contactor will be automatically disconnected to achieve high voltage contact of the entire system, and will not cause a dangerous state in which the high voltage power supply cannot be disconnected.

As shown in the figure, a lithium-ion battery comprehensive safety monitoring system includes a battery module. a battery health management system, at least one relay, and at least one contactor, the battery module is composed of a plurality of single cells in series, the battery module is used to generate a power source, in particular, The battery cell is a single-cell lithium-ion battery; the battery health management system has a data acquisition unit and a data processing unit, and the battery health management system obtains the plural number of each of the single cells by the data acquisition unit The data is processed by the data processing unit, and the battery health management system is used for real-time monitoring of voltage and temperature, total current and total voltage of different positions of each of the single cells, and the battery The health management system further has a sensing unit and a warning unit, wherein the sensing unit is configured to sense and analyze whether the battery module is faulty and Warning unit generates a warning signal; The relay is configured to control voltage balance of the battery module to avoid a voltage difference problem between the battery modules; the contactor is disposed between the battery cells and connected to the relay, the battery The module connects or disconnects the relay by controlling the closing between the contactors. In addition, in particular, when the contactor between the single cells is in a closed state, the relay will be Disconnected to form a parallel mode; please refer to FIG. 3, which is a series and parallel equalization structure diagram of the novel lithium ion battery omnidirectional safety monitoring system. The specific process is as follows: an equalization control module 14 is composed of an array of relays 4. The power resistor and the DC-DC converter are composed of three methods: static natural energy balance, energy transfer equalization, and passive equalization. Under different battery operating conditions, different equalization control strategies are adopted. The three equalization control strategies are: when the system detects that a single minority voltage of the same position in each battery module 2 is inconsistent, the static natural setting is adopted. Equilibrium; when the system detects that a few voltages of different cells in different positions in each battery module 2 are inconsistent, energy transfer equalization is adopted; when the average cell voltage of the entire power supply is lower than some single cells At voltage, these batteries need to be passively balanced to keep the voltage consistent with most of the batteries, thus solving the problem of battery voltage consistency.

第一種均衡控制策略，靜置自然電量均衡控制是實現同一電池模組2內不同基本串聯分支相同位置的單體電池之間的電量均衡和不同電池模組2內相同位置的單體電池之間的電量均衡。 The first equalization control strategy, the static natural power balance control is to realize the power balance between the single cells in the same position of different basic series branches in the same battery module 2 and the single cells in the same position in different battery modules 2 The power balance between the two.

靜置自然電量均衡控制時無需用到DC-DC轉換器。如第3圖所示，通過微處理器DO輸出控制所述均衡控制模組14中各繼電器4的開通和關斷， 實現電池的靜置自然電量均衡。 It is not necessary to use a DC-DC converter when standing the natural power balance control. As shown in FIG. 3, the turn-on and turn-off of each relay 4 in the equalization control module 14 is controlled by the microprocessor DO output. Realize the battery's static and natural power balance.

第二種均衡控制策略，少數單體電池間電量差異較大時，所述動力電池需要進行能量轉移均衡。 In the second equalization control strategy, when the power difference between a few single cells is large, the power battery needs to perform energy transfer equalization.

能量轉移均衡是實現同一電池模組2內，同一基本串聯分支內不同位置的單體電池之間的電量均衡。如第3圖所示，以對基本串聯分支A中的單體電池進行電量均衡為例進行說明，假設基本串聯分支A中電池4和電池3電量未充滿，電池基本模組的電壓接入DC-DC轉換器輸入端，雙通道繼電器K1與DC-DC轉換器輸出埠連接，繼電器K1線圈得電導通後，通過DC-DC轉換器為單體電池4充電，單體電池4充滿後，繼電器K1斷開，繼電器K2導通，通過DC-DC轉換器為單體電池3充電，依次迴圈後，直至所有單體電池容量達到一致。 The energy transfer equalization is to realize the power balance between the single cells in different positions in the same basic series branch in the same battery module 2. As shown in FIG. 3, the battery balancing of the single cells in the basic series branch A is taken as an example. Assume that the battery 4 and the battery 3 in the basic series branch A are not fully charged, and the voltage of the basic module of the battery is connected to the DC. - DC converter input, the two-channel relay K1 is connected to the DC-DC converter output ,, the relay K1 coil is electrically connected, and the single battery 4 is charged by the DC-DC converter. After the single battery 4 is fully charged, the relay K1 is disconnected, relay K2 is turned on, and the single battery 3 is charged by the DC-DC converter, and after looping, until the capacity of all the single cells is consistent.

第三種均衡控制策略，當整個動力電源的絕大多數單體電池電壓均低於某些單體電池電壓時，需要對這些電池進行被動均衡，使其電壓與絕大部分電池保持一致，從而解決電池電壓的一致性問題。如第3圖所示，被動均衡控制策略為例進行說明。以對基本串聯分支A中的單體電池1的電量高於其餘所有單體電池電量，此時就需要進行被動均衡。此時，電池健康管理系統3中的繼電器4陣列和DC-DC轉換器均不啟動，通過控制該電池1並聯的功率電阻的控制開關對電池1進行放電，直至該電池與其餘單體電池容量達到一致。 The third equalization control strategy, when the majority of the cell voltage of the entire power supply is lower than some of the cell voltages, it is necessary to passively balance these batteries so that their voltages are consistent with most of the batteries, thereby Solve the problem of battery voltage consistency. As shown in Figure 3, the passive equalization control strategy is described as an example. In the case of the unit cell 1 in the basic series branch A, the amount of electricity is higher than that of all the other cells, and passive equalization is required at this time. At this time, the relay 4 array and the DC-DC converter in the battery health management system 3 are not activated, and the battery 1 is discharged by controlling the control switch of the power resistance of the battery 1 in parallel until the battery and the remaining single battery capacity Achieve consistency.

請參閱第4圖，係為本創作鋰離子電池全方位安全監控系統啟動瞬間繼電器陣列電氣圖，繼電器陣列中分為兩組K0-K3和K4-K7，繼電器陣列控制通過微處理器DO輸出控制，分為兩種控制狀態： Please refer to Figure 4, which is the electrical diagram of the instant relay array of the lithium-ion battery omnidirectional safety monitoring system. The relay array is divided into two groups K0-K3 and K4-K7. The relay array control is controlled by the microprocessor DO output. , divided into two control states:

1、啟動過程中繼電器控制過程。 1. Relay control process during startup.

在動力電源主串回路中由N個單體電池串聯組成，但是由於單體電池電壓存在一定差異，從而導致數百個串聯組成的動力電源回路後，在總正和總負之間存在一個較大幾伏甚至十幾伏的電壓差，為避免此種危險，在啟動瞬間，每個電池模組2內繼電器陣列K0-K3依次閉合，使每個電池模組2的電壓處於一個無壓差的狀態，這樣在閉合主繼電器時，就能夠完成高壓的建立，避免存在電壓差出現打火放電情況，高壓建立後，繼電器4陣列退出運行。 In the main circuit of the power supply, the N single cells are connected in series, but since there is a certain difference in the voltage of the single cells, resulting in hundreds of power supply circuits in series, there is a larger between the total positive and the negative. In order to avoid such a danger, the relay array K0-K3 in each battery module 2 is sequentially closed at the instant of starting, so that the voltage of each battery module 2 is in a pressure-free manner. State, so that when the main relay is closed, the high voltage can be established to avoid the occurrence of sparking and discharging in the presence of a voltage difference. After the high voltage is established, the relay 4 array is taken out of operation.

2、靜置自然均衡繼電器控制過程。 2. The natural balance relay control process is set.

當動力電源不輸出功率，高壓未建立，且需要均衡時，K0-K3和K4-K7兩組繼電器4按照順序依次吸合，開始整個電池模組2的均衡。 When the power source does not output power, the high voltage is not established, and the balance is required, the two sets of relays K0-K3 and K4-K7 are sequentially sucked in order to start the equalization of the entire battery module 2.

透過本創作此結構的設計，所述電池模組產生的動力電源其電流係主要以串聯連接電路的方式相連接，並透過所述電池健康管理系統提高電壓、溫度及電流的測量精度，另外，於避免電池模組過充電和過放電的控制方面，則可藉由所述感測單元及警示單元以達到判斷電池模組是否故障，若故障則會透過該警示單元產生所述警示訊號，進以達成對該系統的各種性能全方位監控，因此，所述電池健康管理系統能夠即時監控到每個單體電池的電壓狀態，具備了對電池模組故障的即時分析能力，對電池模組的濫用進行預警和報警的提醒，對分析故障原因、故障定位提供方便，為電池的維護提供便利；於均衡方面，增加了電池的均衡控制能力，提出了電池模組之間單體電池均衡方法，具備靜置自然均衡和被動均衡等均衡措施。 Through the design of the structure of the present invention, the current source of the power source generated by the battery module is mainly connected in a series connection circuit, and the measurement accuracy of voltage, temperature and current is improved through the battery health management system. In order to avoid the control of overcharging and overdischarging of the battery module, the sensing unit and the warning unit can be used to determine whether the battery module is faulty. If the fault occurs, the warning signal is generated through the warning unit. In order to achieve comprehensive monitoring of various performances of the system, the battery health management system can instantly monitor the voltage state of each single cell, and has the ability to analyze the failure of the battery module, and the battery module. Abuse of warnings for warnings and alarms provides convenience for analyzing fault causes and fault location, and facilitating battery maintenance. In terms of equalization, the battery's equalization control capability is increased, and a cell balancing method between battery modules is proposed. It has equalization measures such as static natural equilibrium and passive equilibrium.

於本創作中，係以鋰離子電池全方位安全監控系統用於一電動汽車為例進行說明(圖中未示)，該電動汽車發動時，所述電池健康管理系統(HBMS)對整個動力電源進行全方位資料監控，當全方位監控資料完全正常時，發出高壓建立指令，首先該繼電器開始產生閉合狀態，幾秒後所述接觸器也為閉合狀態，閉合完成後，斷開所述繼電器，進以達到完成整個動力電源串聯方式並實現高壓建立；而若當資料處理單元發現某個資料出現問題(例如：單體電池出現電壓過低，絕緣監測警示或者運行時出現車禍等等)，能夠禁止閉合或瞬間斷開整個動力電源的高電壓狀態，實現動力電源的安全低電壓狀態，避免造成不必要的二次傷害。 In this creation, the lithium-ion battery omnidirectional safety monitoring system is used for an electric vehicle as an example (not shown). When the electric vehicle is started, the battery health management system (HBMS) is applied to the entire power source. Perform all-round data monitoring. When the omnidirectional monitoring data is completely normal, a high-voltage establishing command is issued. First, the relay starts to produce a closed state. After a few seconds, the contactor is also in a closed state. After the closing is completed, the relay is disconnected. In order to complete the entire power supply series and achieve high voltage establishment; and if the data processing unit finds a problem with a certain data (for example, the voltage of the single battery is too low, the insulation monitoring warning or the car accident during operation, etc.) It is forbidden to close or instantly disconnect the high voltage state of the entire power supply, and realize the safe low voltage state of the power supply to avoid unnecessary secondary damage.

因此，藉由所述電池健康管理系統的控制，進以實現整個系統的高電壓安全解除，達到於危險環境下電池無害化處理，並於電池健康管理系統的監控下，各項資料完全正常以建立整個高壓系統，並藉由該繼電器陣列的控制形成所述電池模組的電壓平衡，避免於串聯情況下整個電池模組之間的壓差問題，最後控制每個電池模組2之間的接觸器閉合後以斷開繼電器，從而完成高壓系統的建立，即為一鋰離子電池全方位安全監控系統之串聯結構，當遇到危險環境時，如電池模組進水、車禍等環境下，所述接觸器會自動斷開，實現整個系統的高電壓接觸，不會造成無法斷開高壓電源的危險狀態。 Therefore, by the control of the battery health management system, the high voltage safety release of the entire system is realized, and the battery is harmlessly processed in a dangerous environment, and under the monitoring of the battery health management system, the data is completely normal. Establishing a whole high voltage system, and forming a voltage balance of the battery module by controlling the relay array, avoiding a pressure difference between the entire battery modules in a series connection, and finally controlling between each battery module 2 After the contactor is closed, the relay is disconnected, thereby completing the establishment of the high-voltage system, which is a series structure of a lithium-ion battery comprehensive safety monitoring system, when encountering a dangerous environment, such as a battery module water inlet, a car accident, etc. The contactor is automatically disconnected to achieve high voltage contact of the entire system without causing a dangerous state in which the high voltage power supply cannot be disconnected.
