Txhawm rau kom ua tiav ntawm lub neej thiab kev ua tau zoo ntawm cov roj teeb lithium-ion, kev them nyiaj kom zoo yog qhov tseem ceeb. Cov kev tshawb fawb tsis ntev los no thiab kev tshawb nrhiav kev lag luam pom zoo cov tswv yim sib txawv: Nickel-Cobalies (NCM lossis Lithium Hlau Phosphate (LFP) roj teeb. Ntawm no yog cov neeg siv yuav tsum paub:
Cov Lus Taw Qhia Tseem Ceeb
- NCM roj teeb: Them rau90% lossis hauv qab norau kev siv txhua hnub. Zam kev them nqi (100%) tshwj tsis yog tsim nyog rau kev mus ncig ua si ntev.
- LFP roj teeb: Hos txhua hnub them rau90% lossis hauv qab noyog zoo tagnrho, aLub Limtiam Tag Nrho
- them(100%) yuav tsum tau reciasrate tus nqi xeev (SM) kwv yees.
Vim li cas thiaj zam tau tag nrho cov nqi rau cov roj teeb NCM?
1. Kev ntsuas siab siab ntawm kev ntxhov siab sai sai
NCM roj teeb ua haujlwm ntawm qhov ntau dua qhov ntsuas sab saud piv rau LFP roj teeb. Kev them nyiaj rau cov roj teeb no rau lawv kom lawv cov roj hluav taws xob rau lawv, kom nrawm dua cov khoom siv ntawm cov ntaub ntawv hauv cov cuab yeej. Qhov txheej txheem kev txwv no ua rau muaj peev xwm poob thiab luv lub roj teeb qhov kev siv roj teeb tag nrho.
2. Cell Imbalance pheej hmoo
Cov roj teeb pob muaj cov tshuaj ntau nrog cov khoom siv hluav taws xob vim kev tsim cov kev sib txawv thiab cov hloov pauv hluav taws xob. Thaum them nyiaj rau 100%, qee cov cell tuaj yeem cuam tshuam, ua rau muaj kev ntxhov siab thiab kev tsis txaus siab. Thaum lub tshuab tswj roj teeb (BMS) nquag sib npaug ntawm cov khoom lag luam zoo li Tesla thiab byd tsis tuaj yeem tshem tawm qhov kev pheej hmoo no.
3. SM ROUSATIONATIONS Kev Nyuaj Siab
Cov roj teeb ncm uas nthuav tawm cov voltage voltagent nkhaus, ua rau cov kev kwv yees bortation los ntawm kev qhib cov hluav taws xob (OCV). Hauv kev sib piv, LFP roj teeb tuav tau ze li ntawm kev sib tw voltage nkhaus ntawm 15% thiab 95% som, ua kom dawb so kom dawb unreliable. Yog tsis muaj ib ntus tsub nqi, LFP roj teeb rau kev caiv lawv cov nyiaj so acces. Qhov no tuaj yeem yuam cov bms rau hauv cov qauv tiv thaiv nquag, kev ua haujlwm tsis taus thiab kev noj qab haus huv ntev.
Vim li cas LFP cov roj teeb xav tau cov nqi txhua lub limtiam
Lub lim piam 100% them rau LFP roj teeb ua qhov "pib dua" rau BMS. Tus txheej txheem no tshuav ntawm tes voltagages thiab kho soc tsis muaj tseeb tshwm sim los ntawm lawv cov chaw voltage ruaj khov. Cov ntaub ntawv so kho mob yog qhov tseem ceeb rau BMS kom tiv thaiv kev tiv thaiv zoo, xws li kev tiv thaiv kev tawm tsam lossis ua kom zoo rau kev them tsheb kauj vab. Skipping txoj kev ntsuas hluav taws xob no tuaj yeem ua rau muaj kev laus ntxov lossis npaj txhij txog kev ua haujlwm poob qis.
Kev coj ua zoo tshaj plaws rau cov neeg siv
- NCM cov tswv roj teeb NCM: Ua Ntej Ib Zaug Them Nqi (≤90%) thiab tshwj tseg cov nqi them tag nrho rau qee yam kev xav tau qee zaus.
- LFP cov tswv roj teeb LFP: Tswj txoj kev them txhua hnub 90% tab sis xyuas kom txhua lub limtiam tus kheej them txhua hli.
- Tag nrho cov neeg siv: Zam kev sib cais ntau zaus thiab ntau dhau los ua kom lub roj teeb txuas ntxiv mus rau lub roj teeb.
Los ntawm kev npaj cov tswv yim no, cov neeg siv tuaj yeem txhim kho lub roj teeb divability, thiab ua kom muaj kev txhim khu kev qha cov tsheb hluav taws xob lossis cov khoom siv hluav taws xob.
Nyob twj ywm qhia nrog cov kev hloov tshiab tshiab ntawm cov roj teeb thev naus laus zis thiab kev ua kom muaj kev ruaj ntseg los ntawm kev sau npe rau peb tsab ntawv xov xwm.
