1.BMS Battery Management System yog dab tsi?
BMS Battery Management System feem ntau yog siv rau kev tswj xyuas ntse thiab kev saib xyuas cov roj teeb, tiv thaiv overcharging thiab over-discharging ntawm cov roj teeb, ncua roj teeb lub neej, thiab saib xyuas cov roj teeb.
2.Cheebtsam ntawm BMS
BMS feem ntau yog tsim los ntawm BMU tus tswj hwm, CSC sub-controller, CSU ntsuas module, HVU high-voltage maub los, BTU roj teeb qhov taw qhia chav tsev, thiab GPS kev sib txuas lus module.
3. Lub neej voj voog daim ntawv ntawm BMS
Lub roj teebManagement System (BMS) yog ib qho tseem ceeb ntawm cov tsheb fais fab thiab lwm yam kev siv roj teeb.Nws yog lub luag haujlwm rau kev saib xyuas thiab tswj lub roj teeb qhov xwm txheej kom paub meej tias muaj kev nyab xeeb thiab ua haujlwm tau zoo.Lub neej voj voog ntawm aBMStuaj yeem muab faib ua ob peb theem:
- Kev tsim theem: Thaum lub sij hawm tsim BMS, BMS txoj haujlwm thiab kev teeb tsa yuav tsum tau txiav txim siab raws li yam xws li hom roj teeb, daim ntawv thov scenario, thiabkev ua tau zoo.Cov theem no yuav tsum muaj kev tshawb fawb thiab kev sim kom paub meej tias covBMS tsimua tau raws li qhov xav tau ntawm daim ntawv thov roj teeb.
- Manufacturing theem: Thaum lub sij hawm BMS manufacturing theem, ntau yam khoom ntawm BMS yuav tsum tau ua raws li tus tsim yuav tsum tau thiab assembled thiab kuaj.Cov theem no yuav tsum muaj kev tswj xyuas nruj kom ntseeg tau tias BMS qhov zoo thiab kev ua tau zoo raws li cov qauv tsim.
- Installation thiab debugging theem: Thaum lub sij hawm lubKev teeb tsa BMSthiabdebugging theem, BMS yuav tsum tau muab tso rau hauv lub roj teeb system thiab kuaj thiab debugged.Cov theem no yuav tsum muaj kev saib xyuas zoo thiab ua kom zoo kom ntseeg tau tias kev teeb tsa thiab kev debugging ntawm BMS tsis ua rau lub roj teeb puas lossis cuam tshuam rau nws qhov kev ua tau zoo.
- Kev ua haujlwm thiab kev saib xyuas theem: Thaum lub sijhawm ua haujlwm BMS thiab txij nkawm, kev kuaj xyuas thiab tu yuav tsum tau ua kom ntseeg tau tias kev ua haujlwm zoo thiab kev ua haujlwm ntawm BMS.Cov theem no yuav tsum tau sau cov ntaub ntawv thiab tshuaj xyuas kom sai thiab daws teeb meem thiab txhim kho thiab tswj BMS.
- Nyiaj lausthiabrov ua dua theem: Thaum lub sij hawm BMS so haujlwm thiab rov ua dua tshiab, BMS yuav tsum tau hloov kho lossis hloov raws li lub roj teeb lub neej thiab kev ua haujlwm.Cov theem no yuav tsum taucov ntaub ntawv tsom xamthiab kev ntsuam xyuas los txiav txim seb BMS yuav tsum tau hloov kho lossis hloov pauv li cas thiab yuav hloov kho lossis hloov BMS li cas.
4.Core software ua haujlwm ntawm BMS
Kev ntsuas muaj nuj nqi
(1) Kev ntsuas cov ntaub ntawv yooj yim: saib xyuas lub roj teeb voltage, lub teeb liab tam sim no, thiab roj teeb pob kub.Lub luag haujlwm tseem ceeb tshaj plaws ntawm lub roj teeb tswj system yog ntsuas qhov voltage, tam sim no, thiab qhov kub thiab txias ntawm cov roj teeb hlwb, uas yog lub hauv paus ntawm tag nrho cov kev suav saum toj kawg nkaus thiab kev tswj cov logic ntawm lub roj teeb tswj system.
(2) Rwb thaiv tsev tiv thaiv: Tag nrho cov roj teeb system thiab high-voltage system yuav tsum tau sim rau rwb thaiv tsev los ntawm lub roj teeb tswj system.
(3) High-voltage interlock detection (HVIL): siv los xyuas kom meej qhov kev ncaj ncees ntawm tag nrho cov high-voltage system.Thaum qhov kev ncaj ncees ntawm high-voltage system Circuit Court puas lawm, kev ntsuas kev nyab xeeb yog qhib.
Kev kwv yees muaj nuj nqi
(1) SOC thiab SOH kwv yees: qhov tseem ceeb thiab qhov nyuaj tshaj plaws
(2) Sib npaug: kho SOC x muaj peev xwm tsis sib xws ntawm cov monomers los ntawm kev ntsuas qhov ntsuas.
(3) Kev txwv lub zog ntawm lub roj teeb: lub zog tawm tswv yim thiab cov zis ntawm lub roj teeb raug txwv ntawm qhov sib txawv SOC kub.
Lwm cov haujlwm
(1) Relay tswj: suav nrog lub ntsiab +, lub ntsiab-, them nyiaj relay +, them relay -, pre-them relay
(2) Thermal tswj
(3) Kev sib txuas lus muaj nuj nqi
(4) Kev kuaj xyuas yuam kev thiab lub tswb
(5) Kev ua haujlwm tsis raug
