With the continuous development of lithium battery and its integrated technology, using the energy-storage system of lithium battery go to realize smooth wind energy or Photovoltaic power output, tracking plan generate electricity, participate in system frequency modulation, peak load shifting, the emergency response of transient state active power output, transient state electricity Press a variety of applications such as first support, it has also become feasible scheme, at present existing a variety of different capacities and the battery of capacity levels Energy-storage system is currently running or commercial applications.After battery energy storage system scale is integrated, energy-storage battery monomer, energy-storage battery mould Block and energy-storage battery group and group string are more, cause the scene of extensive battery energy storage power station communication packet to point and field apparatus The workflow of debugging is cumbersome, inefficient, and especially battery lacks effective monitoring means.With energy-storage system this The development of individual Newly Sprouted Things, it is intended to, by the use of lithium battery as energy storage medium, store up electric energy in low power consumption period now It is stored in battery, electric energy is discharged into power network to during peak of power consumption.In order to ensure that the safe and efficient use of lithium battery must have Battery management system is protected to lithium battery, while battery management system will also be led to the current transformer in energy-storage system Letter, participate in the control of electrical power storage and release.The platform for being adapted to the lithium ion battery safety management of large-scale energy storage system exists At least to include battery information harvester and warning message harvester in terms of battery management system, battery can be gathered in real time Battery modules operation conditions in case；The classes such as voltage collecting device, current collecting device and electric quantity collector must also be included As necessary target component acquisition module, to realize monitoring and the O＆M to battery.By computer technology, Industry Control skill Art, communication technology etc., which are combined together, to be completed to monitor the real time execution of battery management system, can understand each electricity in real time The operation conditions in pond, and its running status is adjusted by Process Control System, make energy-storage system in real time in safe and efficient fortune Row state, save management cost and improve the efficiency of management.

Shown in Figure 1, monitoring the circuit framework of monomer battery voltage mainly includes following big module：Multiple moulds It is the natural number more than 1 to intend switch module 100-1,100-2 ... 100-K, the K.Because multiple cells are serially connected company Connect to form battery strings CST, battery strings CST is divided into K groups：First Battery pack group CST1, the second Battery pack group CST2 ... according to This analogizes the battery pack CSTK until K groups.Then first analog switch module 100-1 selection is by the first Battery pack group CST1 The positive pole and negative pole of an arbitrary cell are respectively coupled to first corresponding with the first Battery pack group CST1 An analog switch module 100-1 dual input port, second analog switch module 100-2 are selected the second Battery pack group The positive pole of an arbitrary cell and negative pole are respectively coupled to second corresponding with the second Battery pack group CST2 in CST2 An individual analog switch module 100-2 dual input port, the rest may be inferred, and k-th analog switch module 100-K selections are by the The positive pole of an arbitrary cell and negative pole are respectively coupled to relative with K Battery pack groups CSTK in K Battery pack groups CSTK The k-th analog switch module 100-K answered a dual input port.So any one two-way of analog switch module The input quantity of input port be in the battery pack to match with the analog switch module the positive pole of some cell and Negative pole.

Shown in Figure 1, first analog switch module 100-1 is also configured with first operational amplifier 104-1, and Second analog switch module 100-2 is also configured with second operational amplifier 104-2, and the rest may be inferred, k-th analog switch mould Block 100-K is also configured with k-th operational amplifier 104-K.Although analog switch module possesses many groups and a large amount of cells The dual input port mutually echoed, but it only has a pair of output mouth, then the critically important effect of analog switch module is just It is, its some dual input port remaining other dual input ports failure, so-called dual input port when effective Effectively refer to that unique a pair of output mouth of analog switch module only exports that effective dual input port Input quantity.First operational amplifier 104-1 enters to the voltage difference of first analog switch module 100-1 a pair of output mouth Go relatively and amplify, obtain some cell of first analog switch module 100-1 effective dual input port coupling More accurately cell voltage situation between both positive and negative polarity.Second operational amplifier 104-2 is to second analog switch module 100-2 The voltage difference of a pair of output mouth be compared and amplify, the effective two-way for obtaining second analog switch module 100-2 is defeated Cell voltage situation between some cell both positive and negative polarity of inbound port coupling.The rest may be inferred, k-th operational amplifier 104- K is compared and amplified to the voltage difference of k-th analog switch module 100-K a pair of output mouth, obtains k-th simulation and opens Close the cell voltage situation between some cell both positive and negative polarity of module 100-K effective dual input port coupling.So The output quantity of a pair of output mouth of analog switch module is a certain in the battery pack to match with the analog switch module Voltage difference between the positive pole and negative pole of individual cell, and this voltage difference is original very small and is difficult to perceive, and is put by computing Big device is amplified to the output quantity of a pair of output mouth.

It is shown in Figure 1, although be discussed above analog switch module 100-1 to 100-K each possess it is all it is multigroup with it is big The dual input port that amount cell mutually echoes, but any one analog switch module only has a pair of output mouth, then How to select to allow some dual input port of analog switch module effectively to select to allow other remaining dual input ports Failure is invalid it is necessary to dependent on drive module 101-1 to 101-K.Such as the driving mould that analog switch module 100-K is configured The multi-channel drive signal of block 101-K outputs is in Different Logic state（Such as Binary Zero 0,01,10,11）Integrated mode under switch, and So that paired analog switch module 100-K is only selected under the driving of the multi-channel drive signal of any one logical states It is effective to select a dual input port.So analog switch module be each equipped with drive module and also drive module output it is more Road drive signal switches under the integrated mode of Different Logic state, analog switch module is driven in the multichannel of any one logical states Only select that a dual input port is effective under the driving of dynamic signal, a pair of output mouth of analog switch has only exported The input quantity of that dual input port of effect.
