Kev tsim cov txheej txheem ntawm lub zog cia lithium roj teeb pob (PACK) suav nrog ntau cov kauj ruam, los ntawm kev xaiv cov khoom siv raw mus rau kev sib dhos thiab kev sim ntawm cov khoom kawg. Txhua kauj ruam yuav tsum muaj kev tswj xyuas nruj kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom.
1, Cell sorting thiab grouping:
Kev kuaj thiab kuaj:Ua tib zoo sim cov roj teeb uas yuav khoom thiab pab pawg raws li qhov tsis muaj xws li qhov hluav taws xob, kev tiv thaiv sab hauv, thiab muaj peev xwm. Piv txwv li, qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov sib txawv (cov ntaub ntawv yuav txawv nyob ntawm seb lub roj teeb ntawm tes thiab cov neeg siv khoom xav tau).
Kev faib peev xwm:Qhov sib txawv muaj peev xwm tsis tuaj yeem kuaj xyuas ntawm lub tshuab sorting tsis siv neeg thiab yuav tsum tau muab faib los ntawm lub peev xwm aging txee. Thaum tuaj txog, IQC (Incoming Quality Control) ntawm PACK department yuav tsum tau ua qhov chaw kuaj xyuas. Kev pom zoo tswj ntau yam rau qhov sib txawv ntawm lub peev xwm yog los xyuas kom meej qhov sib xws ntawm cov roj teeb lub hlwb, uas yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua neej ntawm cov lithium roj teeb tom ntej.
2, Sib dhos thiab vuam ntawm cov roj teeb hlwb:
Sib sau cov roj teeb hauv qhov chaw huv thiab qhuav kom tsis txhob muaj kev puas tsuaj los ntawm cov plua plav, noo noo, thiab lwm yam.
Cell sib dhos Fixture:Thaum txhim kho cov hlwb mus rau hauv lub fixture raws li tus qauv tsim, nws yog ib qho tsim nyog yuav tsum tau ua raws li qhov zoo thiab tsis zoo electrode ib ntus ntawm cov hlwb hauv SOP (Standard Operating Procedure) tsim los ntawm PE engineer rau kev sib dhos, txwv tsis pub muaj teeb meem loj xws li xov tooj ntawm tes. luv circuits yuav tshwm sim.
Raws li txoj kev npaj tsim, kho cov roj teeb uas tau muab faib ua pawg nrog cov khoom siv los yog cov tais kom ruaj khov thiab ruaj khov kev sib txuas ntawm cov hlwb. Siv cov kev ntsuas rwb thaiv tsev tsim nyog, xws li siv cov khoom siv rwb thaiv tsev, rwb thaiv tsev daim kab xev, thiab lwm yam., txhawm rau tiv thaiv luv luv Circuit Court ntawm cov roj teeb.
Welding kev ua haujlwm:Tom qab teeb tsa qhov kev pab cuam lub tshuab vuam tsis siv neeg, ua qhov chaw vuam tsis siv neeg. Tom qab qhov chaw vuam tiav lawm, cov neeg ua haujlwm zoo yuav tsum tau ua qhov kev tshuaj xyuas tag nrho ntawm cov ntsiab lus vuam kom pom tias puas muaj kev cuam tshuam, tawg, lossis lwm yam teeb meem. Yog tias muaj, lawv yuav tsum tau kho kom raws sijhawm.
3, Box sib dhos:
Kev teeb tsa lub thawv vaj huam sib luag, BMS loj board, connectors, thiab dai pob ntseg
Kev teeb tsa ntawm B + B-xaim hlua
Siv cov khoom siv rwb thaiv tsev
4, BMS sib dhos thiab debugging:
1. BMS sib dhos
Electrostatic tiv thaiv:Cov neeg ua haujlwm yuav tsum hnav lub hnab looj tes electrostatic thaum ua haujlwm, vim tias hluav taws xob zoo li qub tuaj yeem ua rau PCM / BMS puas thiab cuam tshuam rau nws txoj haujlwm ib txwm muaj.
Txuas lub BMS rau cov roj teeb lub hlwb, kom ntseeg tau tias cov kab kev sib txuas yog raug thiab ruaj ntseg. Ua tib zoo saib xyuas qhov chaw teeb tsa ntawm BMS, uas yuav tsum yooj yim rau cov cua sov dissipation thiab txij nkawm, thaum tsis txhob cuam tshuam sab nraud thiab cuam tshuam.
Npaj thiab kho cov kev sib txuas ntawm cov xov hlau ntawm BMS, thiab siv cov tais cable, zip ties, thiab lwm txoj hauv kev rau kev xaim los ua kom cov kab zoo thiab ua kom zoo, txo cov kev pheej hmoo ntawm kab tsis ua haujlwm.
Collection kab welding:Yog tias BMS tau tsim los pom qhov sib txuas ntawm lub roj teeb pob, tsis tas yuav tsum tau vuam. Cov neeg ua haujlwm zoo yuav tsum tau tshuaj xyuas qhov chaw vuam cov ntsiab lus ntawm BMS thiab cov roj teeb pob; Yog tias BMS xav tau kev sib txuas rau cov ntsia hlau, cov chaw kuaj xyuas yuav tsum tau ua ntawm cov pob qij txha thiab cov ntsia hlau txuas. Rau cov kab hluav taws xob tau txais hluav taws xob, lawv yuav tsum tau txuas nrog hauv ntu (xws li B -, B1 ... rau B +), lossis welded tom qab tshem tawm qhov hluav taws xob tau txais kab hluav taws xob. Tom qab vuam, lub qhov (socket) tau txais yuav tsum tau kuaj xyuas thiab paub tseeb tias muaj tseeb ua ntej txuas mus rau BMS.
2. BMS debugging
Teem thiab debug qhov tsis sib xws ntawm cov teeb tsa BMS, thiab teeb tsa kev them nqi tsim nyog thiab tso tawm kev tiv thaiv qhov pib, ntsuas qhov ntsuas, kev sib txuas lus raws tu qauv, thiab lwm yam. Piv txwv li, teem lub overcharge voltage tiv thaiv tus nqi rau 1.1 npaug ntawm qhov ntsuas hluav taws xob ntawm lub roj teeb ntawm tes, thiab tus nqi tiv thaiv overdischarge voltage rau 0.9 npaug ntawm qhov ntsuas hluav taws xob ntawm lub roj teeb ntawm tes.
Kuaj thiab txheeb xyuas qhov kev ua haujlwm ntawm BMS los ntawm kev simulating cov txheej txheem them thiab tshem tawm. Txheeb xyuas qhov tseeb ntawm kev saib xyuas roj teeb, qhov sib npaug, thiab kev tiv thaiv kev ua haujlwm ntawm BMS kom ntseeg tau tias lub zog ntim roj teeb tuaj yeem tswj tau zoo thiab tiv thaiv thaum ua haujlwm.
5, Semi tiav rwb thaiv tsev:
Kho thiab tiv thaiv:Yuav tsum kho thiab rwb thaiv tsev kho mob yuav tsum tau nqa tawm nyob rau hauv voltage acquisition kab, xov hlau, zoo thiab tsis zoo tso zis kab, thiab lwm yam. Cov khoom siv feem ntau muaj xws li high-temperature adhesive tape, barley paper, epoxy board, zip ties, etc. Thaum lub sijhawm ua haujlwm, nws Nws yog ib qho tsim nyog los xyuas kom meej qhov kev ntseeg tau ntawm kev ntsuas rwb thaiv tsev thiab zam kev cuam tshuam kev cuam tshuam thiab luv luv Circuit Court txaus ntshai ntawm kab.
Tsis txhob nyem:Yuav tsum muaj kev paub txog kev nyab xeeb, thiab tsis txhob muab cov kab los yog cov kab hluav taws xob tso tawm los yog cov khoom tso tawm ntawm lub roj teeb pob kom tsis txhob ua rau lub voj voog puas vim yog nyem thiab ua rau luv luv.
6, Semi tiav cov khoom kuaj:
Kev kuaj niaj hnub:Tom qab ntxiv BMS rau lub pob roj teeb, ib qho kev xeem khoom ib nrab yog ua tiav. Cov khoom kuaj niaj hnub muaj xws li kev kuaj xyuas yooj yim thiab tso tawm, tag nrho pab pawg hauv kev ntsuas kev tiv thaiv, tag nrho pab pawg muaj peev xwm kuaj, tag nrho pab pawg overcharge test, tag nrho pab pawg overdischarge test, short circuit test, overcurrent testing, thiab lwm yam.
Kev kuaj tshwj xeeb:Raws li cov kev cai tshwj xeeb ntawm cov khoom, qhov kub thiab txias, tsis tshua muaj kub, koob puncture, poob, ntsev tsuag thiab lwm yam kev ntsuam xyuas kuj yuav tsum tau, tab sis cov kev ntsuam xyuas tshwj xeeb no puas tsuaj thiab feem ntau pom zoo kom ua random soj ntsuam. Thaum lub sij hawm sim, yuav tsum tau them nyiaj mloog mus rau lub roj teeb pob lub peev xwm los tiv thaiv high voltage, xws li seb lub BMS tuaj yeem tiv taus high voltage thaum lub sij hawm overcharge test, seb BMS tuaj yeem tiv taus tam sim no high voltage thiab tam sim no thaum lub sij hawm luv luv-circuit test, thiab seb BMS tuaj yeem tiv taus pulse tam sim no thaum kuaj overcurrent.
7, Test validation:
Ua cov kev ntsuam xyuas tag nrho ntawm lub ntim ntim lub zog ntim roj teeb, suav nrog kev ntsuas kev muaj peev xwm, kev ntsuas kev tiv thaiv sab hauv, kev sim lub neej voj voog, kev ntsuas kev nyab xeeb, thiab lwm yam. Piv txwv li, ua cov nqi them thiab tawm lub voj voog mus kuaj xyuas lub peev xwm tuav tau thiab lub voj voog lub neej ntawm lub roj teeb. pob; Ua kev ntsuas luv luv, kev ntsuas hluav taws xob ntau dhau thiab kev tso tawm ntau dhau, ntsuas koob txhaj tshuaj, thiab lwm yam.
Tshawb xyuas thiab ntsuas cov txiaj ntsig kev xeem, rov ua dua lossis cov khoom seem uas tsis ua raws li qhov yuav tsum tau ua, thiab ua kom ntseeg tau qhov zoo ntawm lub zog cia roj teeb pob uas tawm hauv lub hoobkas.
8, Ntim:
Kev kho rwb thaiv tsev:Ua ntej ntim, cov teeb liab tau txais kab thiab qhov zoo thiab qhov tsis zoo ntawm lub pob roj teeb yuav tsum tau insulated los xyuas kom meej tias lub roj teeb pob yuav tsis ua rau luv luv Circuit Court lossis lwm yam txhaum vim yog kev sib cuag nrog cov teeb meem thaum lub sij hawm ntim khoom.
Txheej txheem ntim:Xaiv cov txheej txheem ntim sib txawv raws li kev tsim qauv. Piv txwv li, PVC ntim cov roj teeb yuav tsum muaj lub tshuab ua kom sov, cov roj teeb ntim ultrasonic yuav tsum muaj lub tshuab ultrasonic, thiab cov roj teeb ntim nrog cov thawv hlau sab nrauv yuav tsum muaj lub thawv sib dhos. Thaum lub sij hawm ntim cov txheej txheem, yuav tsum tau ua tib zoo saib xyuas, kom tsis txhob muaj kev sib tsoo, sib tsoo, thiab lwm yam xwm txheej los tiv thaiv kev puas tsuaj rau lub pob roj teeb.
