Switch module 20 is arranged on the cell circuit C, in order to cut-out or the conducting of decision cell circuit C.In one embodiment of this invention, switch module 20 comprises charge switch circuit 21, discharge switching circuit 22 and fuse 23.Charge switch circuit 21 can be made up of metal oxide semiconductor transistor with discharge switching circuit 22, but the present invention is not as limit.Whether whether charge switch circuit 21 can charge with decision battery unit 11 through charging control signal control, and 22 of discharge switching circuits pass through discharge control signal control, can be to electronic installation 1 discharge with decision battery unit 11.23 of fuses pass through the control of fuse control signal, when fuse 23 opens circuit cell circuit C, and just permanent failure of battery module 10.
Therefore, can know that switch module 20 can have five kinds of operating states by above-mentioned description.When fuse 23 opened circuit, battery module 10 was in the state of permanent failure.When fuse 23 conductings, and charge switch circuit 21 and discharge switching circuit 22 be all during conducting, and 10 of battery modules can charge and discharge; When charge switch circuit 21 opens circuit and during discharge switching circuit 22 conductings, battery module 10 can't charge and can discharge; When charge switch circuit 21 conductings and discharge switching circuit 22 when opening circuit, battery module 10 can charge and can't discharge; When charge switch circuit 21 and discharge switching circuit 22 all opened circuit, 10 of battery modules can't charge and discharge.
Switch module 20 is controlled through safety control module 13.Safety control module 13 electrically connects with measurement module 12 and switch module 20, with the measuring-signal control switch module 20 according to measurement module 12.Safety control module 13 can utilize hardware, software or firmware to constitute, but the present invention is not as limit.In addition; Whether safety control module 13 can detect battery module 10 and engage with electronic installation 1; Or accept the control of electronic installation 1 and produce a plurality of time control signals; For example produce a plurality of chargings time control signal to control charge switch circuit 21, a plurality of discharges time control signal is controlled signal with control fuse 23 with control discharge switching circuit 22 and a plurality of fuse, but the present invention is not as limit.
Time module 17 electrically connects with battery module 10 interior identification modules 14, in order to the generation time signal.When battery module 10 is produced completion in its manufacturer, time module 17 will be reset and make zero, and continue to count with a stable 1Hz frequency.The numerical value of numeration promptly is time signal, represents battery module 10 to produce the time that the back is experienced.In addition, battery module 10 also can write down a date of production when producing completion, utilizes the fixing date of production and the time signal that continues to accumulate, and this time reference that battery module 10 conforms to real world just can be provided.
Identification module 14 electrically connects with measurement module 12, safety control module 13 and time module 17, in order to receive measuring-signal, control signal and time signal.Identification module 14 can be and utilizes hardware, software or firmware to constitute, but the present invention is not as limit.When measuring-signal changed its residing interval or its state of control signal change, identification module 14 produced note will data to write memory module 30 with measuring-signal, control signal and time signal at that time.
Then ask the sketch map of while with reference to figure 3 memory modules of the present invention.
In one embodiment of this invention, memory module 30 can be an EEPROM (Electrically-Erasable Programmable Read-Only Memory, EEPROM), but the present invention is not as limit.Memory module 30 comprises Control Parameter district 31, characterisitic parameter district 32 and note will data field 33.Control Parameter district 31 and characterisitic parameter district 32 are the initial setting of battery module 10, when plant produced, just write; 33 of note will data fields are the running according to battery module 10, in order to write down the note will data that produced by identification module 14.In one embodiment of the present invention, memory module 30 can have the memory space of 4096 bytes, and wherein Control Parameter district 31 is 16 bytes, and characterisitic parameter district 32 is 128 bytes, and note will data field 33 then is 3952 bytes.The various parameters that Control Parameter district 31 storage battery modules 10 management memory module 30 is required, it is not emphasis of the present invention place, so repeat no more at this.
Characterisitic parameter district 32 is the measuring-signal in the note will data and the basic setting of control signal, comprises that the measurement parameter of store measuring-signal sets 321 and the Control Parameter setting 322 of control signal.All there is one group in the measuring-signal of each voltage, electric current and the temperature of being stored in the note will data field 33 in measurement parameter setting 321 sets basically, so measurement parameter setting 321 can comprise denominational 321a, critical point hurdle 321b, sluggish hurdle 321c and control group 321d.In one embodiment of the present invention, each group measurement parameter is set 321 and can be had 11 bytes, and wherein denominational 321a is 4 bytes, and critical point hurdle 321b is 5 bytes, and sluggish hurdle 321c and control group 321d are 1 byte.
The title of denominational 321a storage different measuring signal representes with the form of ASCII that in the present embodiment so each measuring-signal can use 4 letter designations, but the present invention is not as limit.
Critical point hurdle 321b is in order to set a plurality of critical points of each measuring-signal.Below please refer to the sketch map of the critical point that measurement parameter had in Fig. 4 one embodiment of the invention.Critical point shown in Figure 4 is the example explanation with the voltage signal of a certain economize on electricity core in the battery unit 11.The critical point of voltage signal is set at second overdischarge and presses critical point 40, first overdischarge to press critical point 41, zero dump energy critical point 42, the first overcharged voltage critical point 43 and the second overcharged voltage critical point 44, and further the nominal working range of battery unit 11 is divided into first interval 51 to the 6th interval 56.Therefore, the magnitude of voltage of the voltage signal that measures through measurement module 12 can learn which interval range voltage signal is in.
In addition, the setting of critical point hurdle 321b also can be sent to safety control module 13 and measuring-signal relatively, and comparative result is produced control signal is sent to switch module 20.In one embodiment of this invention; Setting the critical point 40 of second overdischarge pressure is 1.0 volts; It is 2.4 volts that critical point 41 is pressed in first overdischarge, and zero dump energy critical point 42 is 3.0 volts, and the first overcharged voltage critical point 43 is that 4.2 volts and the second overcharged voltage critical point 44 are 4.4 volts.The normal range of operation of battery unit 11 is in the 4th interval 54, and the time service of battery unit 11 overwhelming majority is in this interval.After first interval 51 was worked in battery unit 11, when next time, charging provided enough energy, safety control module 13 promptly can cut off fuse 23 through the fuse control signal.When battery unit 11 is operated in second intervally 52 the time, safety control module 13 promptly can cut off discharge switching circuit 22 through discharge control signal.If work the 5th interval 55 o'clock in battery unit 11, safety control module 13 promptly can cut off charge switch circuit 21 through charging control signal during charging.If work the 6th interval 56 o'clock in battery unit 11, safety control module 13 promptly can cut off fuse 23 through the fuse control signal during charging.Likewise, different measuring-signals like signals such as electric current or temperature, all applicable to this principle of classification, but is not limited to have five critical points.
Sluggish hurdle 321c is in order to the parameter of storage lag time.Because the disturbance of the electronic signal in the charge and discharge process of battery module 10 and the electronic installation 1 can cause measuring-signal in different intervals, to beat back and forth.For avoiding the signal errors of circuit, therefore need to consider lag time.For example; If voltage signal is in second interval 52; And the numerical value of voltage signal presses the time of critical point 41 to need greater than lag time above first overdischarge, can confirm just that thus voltage signal is genuine the 3rd interval 53 that gets into because of the magnitude of voltage of battery unit 11.
Control group 321d is the option of this measuring-signal of management, and non-emphasis of the present invention place is so repeat no more at this.
Each control signal of being stored in the note will data field 33 is all set 322 existence in Control Parameter and is set basically for one group, so Control Parameter setting 322 can comprise denominational 322a and control group 322b.Because control signal only has the two kinds of signals in " pass " and " opening " (i.e. " 0 " and " 1 "), does not therefore need measurement parameter to set critical point hurdle 321b and sluggish hurdle 321c in 321.In one embodiment of the present invention, Control Parameter sets 322 can have 5 bytes, and wherein denominational 322a is 4 bytes, and control group 322b is 1 byte.Denominational 322a is in order to store the title of different control signals, and likewise the form of available ASCII is represented, but the present invention is not as limit.The option of this control signal of control group 322b management is not emphasis of the present invention place, so repeat no more at this.
The note will data that note will data field 33 is produced by identification module 14 in order to storage.Each note will data includes time signal hurdle 33a, measuring-signal hurdle 33b and control signal hurdle 33c, and writes note will data field 33 successively.Time signal hurdle 33a is in order to store the time signal of each note will data; Measuring-signal hurdle 33b is in order to each measured measuring-signal of storage measurement module 12, and control signal hurdle 33c is in order to the control signal and time control signal condition of storage security control module 13.
In one embodiment of this invention; Because there is the space of 128 bytes in characterisitic parameter district 32; Each group measurement parameter sets 321 needs 11 bytes; Each Control Parameter sets 322 needs 5 bytes, so characterisitic parameter district 32 can be designed to 8 measuring-signals of being made up of voltage, electric current and temperature and control signal and time control signal that adds up to 8, and each measuring-signal can be named by denominational 321a or 322a.In addition; Each time signal is 4 hyte length; Each measuring-signal is 1 hyte length; Each control signal is 1 bit length, thus more than comprise 8 measuring-signals and 8 control signals and time control signal every group of note will data totally 13 hyte length, form by the time signal hurdle 33a of 4 bytes, the measuring-signal hurdle 33b of 8 bytes and the control signal hurdle 33c of 1 byte.Therefore as if the memory module 30 with 4096 bytes, the note will data more than 300 just can be deposited in the note will data field 33 of its 3952 byte.
Alarm module 15 electrically connects with memory module 30, in order to analyze the note will data field 33 in the memory module 30, to judge battery module 10 whether abnormality is arranged, and sends alarm signal again.Alarm module 15 can be and utilizes hardware, software or firmware to constitute, but the present invention is not as limit.The standard that alarm module 15 is judged can be according to note will data frequency and number of times, but the present invention is not as limit.For example, alarm module 15 time for reading signal hurdle 33a, when the time signal gap of continuous several note will data is specific less than one apart from the time, can represent the time of note will data record more frequent, so alarm module 15 promptly sends alarm signal.When this is specific apart from parameter setting in memory module in 30 the Control Parameter district 31.On the other hand, when the sum of note will data surpassed the note will upper limit parameter of setting, alarm module 15 also sent alarm signal.This upper limit parameter is set in the Control Parameter district 31 of memory module 30,300 in the foregoing description for example, but the present invention is not exceeded with this quantity.
Then please refer to the flow chart of steps of the method for Fig. 5 recording cell module by signal of the present invention.Be noted that here, though below be the method for example explanation recording cell module by signal of the present invention with battery module 10, the method for recording cell module by signal of the present invention is not so that be used in battery module 10 and exceed.
At first carry out step 501: when a battery module is produced, reset and start a time signal.
When battery module 10 is produced completion in its manufacturer, the time module 17 in the battery module 10 will be reset and make zero, and continue to count the generation time signal with a stable 1Hz frequency.
Carry out step 502 again: the state that detects this battery module to be obtaining a measuring-signal, and divides the residing operation interval of this measuring-signal.
At first measurement module 12 detects the state of battery module 10, comprises the voltage and temperature, the electric current of cell circuit C and the temperature of switch module 20 that detect battery unit 11, to obtain measuring-signal.And be noted that battery module 10 does not limit and need under situation about electrically connecting with electronic installation 1, just can obtain measuring-signal.Voltage signal with a certain batteries is an example; The measuring-signal that in this step 502, obtains also is divided into some intervals; Promptly, the measuring-signal that obtains is divided in the wherein interval that is in first interval 51 to the 6th intervals 56 according to the setting of critical point hurdle 321b.
Next carry out step 503: utilize a control signal to control a switch module.
Safety control module 13 inside can produce a plurality of charging control signal parallel connection integrated charge control signals with control charge switch circuit 21, and a plurality of the integrated discharge control signals of discharge control signal parallel connection are to control discharge switching circuit 22 and a plurality of the integrated fuse control signals of fuse control signal parallel connection with control fuse 23.Whether the control of measuring-signal, electronic installation 1 and detection battery module 10 engage with electronic installation 1, all can produce the control signal above time, but the present invention are not as limit.
Then carry out step 504: receive this measuring-signal, this control signal and this time signal, and maybe when this control signal changes, obtain note will data when this measuring-signal changes residing interval.
Then identification module 14 receives the measuring-signal of measurement module 12 and the control signal of safety control module 13 simultaneously; And when measuring-signal changes its interval of living in or its state of control signal change; Just the time signal of time of reception module 17 is to become note will data with measuring-signal, control signal and time sets of signals simultaneously.The measuring-signal of for example a certain economize on electricity core voltage changes at first interval 51 o'clock by second interval 52, and identification module 14 produces note will data.Likewise, when arbitrary control signal was changed into " opening " by " pass " or changed into " pass " by " opening ", identification module 14 also produced note will data.The content of note will data comprises at that time time signal, measuring-signal and control signal.Because time signal is to be to produce unit with 1HZ, so a plurality of measuring-signals of producing of unit change the interval or control signal changes state at one time, will by and close and only can produce note will data.
Carry out step 505 again: store this note will data.
Then the note will data that produced of memory module 30 storage identification modules 14 are in note will data field 33.Memory module 30 is also deposited the measurement parameter setting 321 of predefined measuring-signal and the Control Parameter of control signal and is set 322 except note will data.
Then carry out step 506: analyze these note will data and judge whether this battery module is unusual.
Whether then alarm module 15 is analyzed the note will data of the note will data field 33 of memory module 30, unusual to judge battery module 10.Promptly read several note will data; Analyze the time signal of its time parameter hurdle 33a, the measuring-signal of measuring-signal hurdle 33b and the control signal of control signal hurdle 33C; Whether have unusual condition, but the present invention is not exceeded with the above-mentioned mode of enumerating according to the frequency of remembering the generation of will data and number of times if can judge battery module 10.
If alarm module 15 judges that the content of note will data is not unusual, then carry out step 504 again, judge again to obtain new note will data whether battery module 10 is unusual.
If alarm module 15 judges that the content of note will data is unusual, then further carry out step 507: send an alarm signal.
If alarm module 15 is judged battery module 10 unusual condition is arranged; As described before judges unusual condition according to note will data frequency and number of times; Then alarm module 15 sends alarm signal, and transfers to electronic installation 1 via communication module 16, to be shown on the electronic installation 1.
Carry out step 508 at last: read these note will data and remove this alarm signal.
When unusual battery module 10 or the battery module 10 that alarm signal occurs are delivered to helpdesk; Can use a computer system or other maintenance analysis system via a connectivity port access communications module 16; Read out note will data; And form that can e-file is sent to a long-range receiving terminal (figure does not show), for example battery module 10 manufacturers.These note will data also can be made into figure or form in helpdesk and long-range receiving terminal, to carry out the analysis to this battery module 10.Last for the battery module that alarm signal occurs 10, computer system system removes the alarm signal of alarm module 15 via connectivity port and communication module 16.
Be noted that here the method for recording cell module by signal of the present invention is not exceeded with above-mentioned order of steps, as long as can reach the object of the invention, but the also change of above-mentioned order of steps.
Method through above-mentioned battery module 10 and record gets final product the internal information of omnidistance recording cell module 10, and can save the memory space of memory module 30.The note will data of these omnidistance records can make the analysis of unusual battery module 10 more effectively reach conveniently, need not destroy battery module 10.And, can this be remembered that the will data are sent to long-range receiving terminal with electronic document format, further directly to analyze battery module 10 through electronic document format in long-range receiving terminal.Thus, make the analytical work of unusual battery module 10 to carry out everywhere, and do not need the entity of unusual battery module 10.
