Describe in detail below in conjunction with the battery protecting apparatus 420 among the Fig. 4 of Fig. 5.
Battery protecting apparatus 420 mainly comprises balanced unit 502, PIC16F833 chip, QZ8940 signal chip, signal processing module (BQ77PL900 chip), external communication 508 and loop break-make control module (discharge MOS504, charging MOS506).
This system adopts hardware protection and two circuits of software collection to carry out simultaneously:
1, the BQ77PL900 chip design of special-purpose li-ion cell protection chip TexasInstruments company is adopted in cell hardware protection, this chip can overcharge single-unit lithium electricity (battery pack is made of 13 string single-unit lithium electricity), cross put, protections such as overcurrent, short circuit; The simultaneously integrated passive equalization function of hardware can be carried out equilibrium according to the inconsistent shunt resistance that adopts of single-unit in the battery pack by balanced unit 502; Major loop adopts the MOS switch to control the break-make of battery pack output; Charging MOS506 overcharges tripping protection metal-oxide-semiconductor integrated circuit for charging; Discharge MOS504 is external short circuit or overdischarge tripping protection metal-oxide-semiconductor integrated circuit; B-has sample resistance between the metal-oxide-semiconductor to discharging, detect discharging current, realizes that overcurrent detects protection and short-circuit detecting protection.
2, the collection of battery software data is the voltage of gathering single battery by the OZ8940 chip, and the single-unit voltage signal of gathering is transferred to the central data processing unit; The data that while current sample and temperature sampling obtain are passed to the central data processing unit equally and are carried out data output and data upload; Central data processing unit core component is the MCU chip of load data processing and data communication: the PIC16F833 single-chip microcomputer; Through the data operation integrated treatment; judge whether to carry out the charge and discharge protection; when being; fill order is passed to discharge MOS504 and charging MOS506; metal-oxide-semiconductor can turn-off the charge or discharge circuit; the status data of battery is again by external communication 508(serial ports monobus UART mouth) data are passed to radio communication device 510; radio communication device 510 is uploaded to host computer server in the Surveillance center 512 with this status data; the host computer server carries out data monitoring and management computing, to realize protection and the management to lithium battery.Judge that according to the battery status data storage battery sends when unusual in Surveillance center 512, control command can be sent to gps data transducer 510 by uploading the loop, and the break-make by PIC16F833 Single-chip Controlling charging MOS506 and discharge MOSS504.
The design philosophy that system adopts software to combine with hardware has been considered hardware and software shortcoming separately comprehensively, and has been remedied mutually; Be responsible for cell safety protection part and must adopt special-purpose integrated hardware protection circuit, its antijamming capability is strong, protection reliability height; What be responsible for data acquisition, data processing and data upload must be core with the MCU single-chip microcomputer, carries out software and handles, and software is handled flexibility far above hardware circuit; Two circuits of software and hardware do not disturb mutually, interknit again, have reached intelligent reliable purpose.
The handling process of prescribed server below in conjunction with Fig. 6.
Data such as the voltage of the battery that battery protecting apparatus is gathered, electric current, temperature, capacity are wirelessly transmitted in the host computer server by gsm module, and upper server can resolve, analyze and handle these data.By the analysis to data, can find the battery abnormal problem effectively, inform the user in advance, can avoid reaching unusually safety problem.
In step 602, server receives the battery status data that battery protecting apparatus is uploaded.In step 604, judge whether this status data is carried out calculation process, if not, then finish this flow process, if then enter step 606.In step 606, based on status data, judge the malfunction of storage battery.Determine the classification of malfunction according to judged result in step 608.In step 610, malfunction roughly is divided into two classes, one class for example is mobile alarm, overload warning, overspeed alarming, high temperature alarm, undervoltage warning, illegally opens that electric door lock is reported to the police, fault alarm, another kind of for example be overcharge warnings, cross put that warnings, dehydration are reported to the police, sulfuration warning, short-circuit alarming, break lattice warning, unbalance warning.Whether detection failure is removed, if then enter step 612, otherwise continue the classification of failure judgement.It should be noted that; when breaking down; server can generate corresponding control command according to fault type; and control command is sent to battery protecting apparatus; battery protecting apparatus is carried out corresponding actions and is reported to the police after receiving corresponding control command; realize the purpose of remote protecting storage battery, avoid dangerous and take place.Secondly, when breaking down or when unusual, can reminding the user by modes such as note, phones.
In step 612, battery protecting apparatus enters resting state after the trouble shooting.
In step 614, determine whether to wake battery protecting apparatus up according to outer triggering signal, for example if programmable button is pressed, shows and will wake battery protecting apparatus up, then enter step 616, if programmable button is not pressed, then finish this flow process.In step 616, carry out fault and show, continue to carry out accident analysis according to the battery status data and confirm.
Can find out that from above-mentioned processing procedure server mainly contains following function:
1. battery data analysis
According to battery single-unit voltage signal, adopt the variance technology, server can be analyzed this signal on the backstage, draws the consistency problem between the battery single-unit, and to battery capacity and Influence on security, a situation arises unusually thereby can predict this battery in advance.
2. battery uses prompting unusually
When finding the whole group of battery pack brownout, namely whole group is crossed and is put, and system can remind the user in time to give batteries charging with short message mode automatically, in order to avoid battery pack is influenced cell integrated serviceability by deep discharge; When finding that the whole group of battery pack is overcharged, whether system can remind the user to go maintenace point maintenance charger unusual with short message mode automatically, in order to avoid often use unusual charger can cause the cell safety accident.
3. battery failures is handled
According to the battery protecting apparatus collection and the various data on uploading onto the server, background server can be according to the algorithm and the safe thresholding that configure, analyzes automatically and judges whether the battery current state is in safety margin; If battery is unusual, system can send early warning information automatically, and reminds the user in time to overhaul battery to maintenace point with short message mode, produces safety issue in order to avoid battery can further worsen; When further serious problems occurring, system can send alarm signal, must be with phone form emergency notice user, and this moment, safety problem appearred in battery, need carry out relevant treatment immediately.
According to top analysis and the processing procedure that data are carried out, can be before battery occurs when unusual and safety issue occurs, the further deterioration of containment abnormal problem in time can make cell safety be not problem with the of paramount importance safety problem retaining of present lithium battery outside; For lithium electricity from now on provides technical support and safety guarantee at electric bicycle even the development on electric automobile.
