Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The execution mode of the utility model relates to a kind of dynamic lithium battery with built-in SOC monitoring and communication function; As shown in Figure 1; Comprise battery case 1, be placed with battery cell in the said battery case 1, said battery case 1 is provided with positive pole 2 and negative pole 3; Said battery cell is provided with anodal syndeton body 4 and negative pole syndeton body 5; Said anodal 2 link to each other with anodal syndeton body 4, and said negative pole 3 links to each other with negative pole syndeton body 5, also is provided with the embedded monomer battery management system 6 that links to each other with external system in the said battery case 1; Said anodal 2 and anodal syndeton body 4 between be provided with current sensor 7, be provided with current sensor 7 between said negative pole 3 and the negative pole syndeton body 5, said current sensor 7 links to each other with said embedded monomer battery management system 6; Said anodal 2 and negative pole 3 between be provided with voltage sensor 8, said voltage sensor 8 links to each other with said embedded monomer battery management system 6.
Wherein, the positive pole 2 on the battery case 1 is connected use with negative pole 3 for the outside, and the anodal syndeton body 4 on the battery cell is connected use with negative pole syndeton body 5 for inside.
The structure of embedded monomer battery management system 6 can be circuit board form (like the Based Intelligent Control plate), also can be chip form (like intelligent chip), when batch is very big, will be designed to circuit chip.Said embedded monomer battery management system 6 is placed in the headspace in the battery case 1.This part power supply can be taken from this battery, when system hibernates, the extremely low electric current of keeping only is provided.Its external communication can be adopted communication mode or other form of CAN.Through in the production process of battery, embedding Based Intelligent Control plate (or intelligent chip), make all parameters can get into this system, realize the collection and the operational analysis of data; And through CAN or other any communication mode with these parameter unofficial biography; After system will record parameter and analyze, when finding catastrophic failure, the built-in intelligence system of this battery cell can also be made shielding or idle control to battery; It is so-called cell dormancy; The state of dormancy can be realized " parallel connection open circuit or series connection short circuit " function, for advantageous conditions has been created in the safe operation of external system according to original parameter that is provided with.Wherein, its major parameter to battery is measured as: 1, the signature identification parameter of dispatching from the factory of battery (being similar to the identity card characteristic of this battery); 2, the voltage of cell; 3, the operating current of cell (containing) from putting little electric current; 4, through the SOC after the computing; 5, through the dynamic internal resistance of battery after the computing; 6, the temperature of battery; 7, battery failures is disposed state (be manipulated so open-circuit condition after " 1 " expression fault, be manipulated so short-circuit condition after " 0 " expression fault); 8, battery failures is disposed controlled source (" 1 " expression is controlled by external system, and " 0 " expression is controlled by built-in system).This built-in intelligent control management system is that this cell parameter is used; Irrelevant with the battery parameter of outside, this intelligence system (plate or chip), its power supply comes from this monomer self power supply; Can adopt multiple sleep mode, only need the minimum electric current of keeping after its dormancy.
Said current sensor 7 two ends are parallel with the idle short switch 10 by said embedded monomer battery management system 6 controls, when carrying out idle state, current sensor 7 are carried out the power-type short circuit.Said voltage sensor 8 two ends are parallel with the idle open switch 11 by said embedded monomer battery management system 6 controls, when carrying out idle state, voltage sensor 8 are carried out the power-type open circuit.
When using the time spent of this battery as application system or pure electric automobile, entire system will become simply, and the reliability of entire system will strengthen.In the application process of this type systematic, need not special BMS system, need not device or the system special, and, just can realize the measurement and the monitoring of dynamic parameter as long as in application system, increase the communication interface of CAN or its response to the administration configuration of battery.
The parameter that application system is obtained all will obtain through the mode of data communication.
In the communication process of this dynamic lithium battery, data content has comprised (almost having contained all required messages of battery) following message:
1, the production information of battery itself like the characteristic symbol mark, is similar to the birth message of this battery, and this message is by essential authentication code in the battery production process.
2, battery current value, its acquisition are to derive from built-in current sensor.
3, battery voltage value, its acquisition are to derive from built-in voltage sensor.
4, battery temperature value, its acquisition are to derive from built-in temperature sensor.
5, the SOC value of battery, this value are to obtain after the calculating through voltage and current, and the position of being formulated by agreement sends out.
6, the idle on off state message of battery, because when in the system this battery being used for the series-parallel connection mode, this battery is in paralleling model or is in series model, this embedded built-in system is indefinite.But, in case accomplishing, system makes up, the residing position of monomer whose itself is fixing and clear and definite.Therefore, in case this battery gets between age at failure, external characteristic is not quite similar: when being in parallel way, system necessarily hopes to appear open-circuit condition; When being in series system, system necessarily hopes to appear short-circuit condition, and when system handles aptly, as above-mentioned, as far as external system, its influence will be very little, even has no sensation.The reliability and the fail safe of external system like this, have just greatly been improved.
About this State Selection, in the embedded system, be to leave control bit, be used for selecting by external system.
In sum; The utility model is placed in the inside of battery to the observation process of battery cell; The process monitoring of battery is integrated into the production process of battery, makes cell become an intelligence system, be the simplification of application system (or pure electric automobile); Attenuating is lowered the expense of external system to using the process control requirement of system.
