Vim hais tias ib lub hlwb sib txawv ntawm yim yam -voltage, muaj peev xwm, theem them, sab hauv tsis kam, tawm toj siab, thiab qhov sib piv tam sim no tsis tu ncua- tus nqi thiab tso tawm ntawm ib tus neeg lub hlwb hauv lub roj teeb module tsis tuaj yeem synchronized, shortening tag nrho lifespan ntawm roj teeb module.
Yog li ntawd, muaj peev xwm grading yog tsim nyog los xyuas kom meej tias ib tug neeg lub hlwb nyob rau hauv tib lub module qhia cov nram qab no sib xws: voltage; lub neej voj voog; muaj peev xwm; tus kheej- tso tawm; theem nqi; sab hauv tsis kam; tshem tawm toj siab; thiab qhov piv txwv tam sim no.
I. Voltage Consistency
1. Qhov tsis sib xws ntawm qhov hluav taws xob hauv ib lub voj voog yuav ua rau overcharging thiab tshaj - tso tawm, ua rau nws tsis yooj yim rau kev tswj hwm tswj lub roj teeb.
2. Qhov tsis sib xws ntawm qhov hluav taws xob nyob rau hauv ib qho kev sib txuas yuav tsum tau cov roj teeb ua kom them nqi thiab tawm qhov ntsuas kom txog thaum lawv cov voltages zoo ib yam. Txawm li cas los xij, ntau qhov sib txawv ntawm qhov sib txawv ntawm cov modules yuav tshuab lub fuse (PCB board qauv). Qhov tso cai voltage qhov sib txawv ntawm cov fuses yog<0.6V.
3. Ntau dhau qhov sib txawv ntawm qhov sib txawv ntawm cov koob - txuas cov modules tsuas yog daws tau los ntawm kev sib npaug ntawm BMS. Hauv qhov xwm txheej hnyav, kev them nyiaj ceev thiab kev tso tawm lossis tshem tawm cov roj teeb tsis raug yog tsim nyog.
(Lub roj teeb tsis muaj. 3 muaj kev pheej hmoo ntawm dhau- tso tawm)
(Battery No. 3 muaj kev pheej hmoo ntawm overcharge)
II. Muaj peev xwm sib npaug
Kev muaj peev xwm tsis sib xws yog qhov ua rau muaj qhov tsis sib xws ntawm qhov tsis sib xws, uas ua rau muaj kev cuam tshuam ntau dhau thiab dhau - tso tawm txaus ntshai thaum lub sijhawm them thiab tawm.
(Roj teeb Tsis muaj . 2 tau twv yuav raug them ntau dhau thiab tshaj tawm)
ACEY-BCT506-512HLithium roj teeb muaj peev xwm testersiv cov cuab yeej siv hluav taws xob niaj hnub saib xyuas thiab tswj cov khoom siv tsis siv phau ntawv ua haujlwm los saib xyuas qhov tiag - lub sijhawm voltage, tam sim no, muaj peev xwm, lub zog, tsim lub xeev thiab lwm yam tsis muaj kev faib roj teeb hauv lub sijhawm, kuaj xyuas thiab kho qhov tsis raug, sau thiab txheeb xyuas cov ntaub ntawv cuam tshuam, txhawm rau kom paub txog qhov tsis muaj neeg saib xyuas thiab kev ua haujlwm hauv cov txheej txheem tsim.
III. Tus nqi sib npaug
Txawm tias muaj roj teeb muaj peev xwm sib xws, kev them nqi tsis sib xws tseem yuav ua rau overcharge thiab tshaj - tso tawm.
(a. Kev them nyiaj tas mus li yuav ua rau overcharging ntawm No.1 roj teeb.)
(b. Kev tso tawm txuas ntxiv tuaj yeem ua rau overdischarge ntawm No.2 roj teeb.)
IV. Internal Resistance tsis tu ncua
Raws li txoj cai, txhua lub roj teeb ntawm lub cev tuaj yeem muab faib ua ob ntu: lub roj teeb nws tus kheej thiab nws qhov kev tiv thaiv sab hauv. Kev tsis sib haum xeeb sab hauv yuav ua rau asynchronous charging thiab tawm ntawm lub roj teeb nws tus kheej.
