Nrog rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab, cov khoom siv roj teeb pob, raws li lub hauv paus ntsiab lus ntawm lub zog cia thiab kev hloov pauv, tau dhau los ua qhov tseem ceeb ntawm kev lag luam rau kev hloov kho thev naus laus zis thiab kev ua kom zoo dua qub. Los ntawm lub tsheb fais fab mus rau lub zog cia chaw nres tsheb fais fab, los ntawm cov khoom siv hluav taws xob portable mus rau cov khoom siv hluav taws xob hauv kev lag luam, kev ua haujlwm ntawm cov khoom siv roj teeb cuam tshuam ncaj qha rau kev ntseeg siab, kev nyab xeeb, thiab kev them nqi ntawm qhov kawg - siv daim ntawv thov. Tam sim no, kev ua lag luam xav tau kom muaj txiaj ntsig zoo, txawj ntse, thiab cov kev daws teeb meem ntawm cov roj teeb uas muaj kev nyab xeeb yog nce ceev, tsav tsheb mus txuas ntxiv hauv cov thev naus laus zis.
I. Cov ntsiab lus tseem ceeb thiab cov teeb meem ntawm cov khoom siv roj teeb pob
Cov khoom siv roj teeb muaj ntau yam xwm txheej, tab sis nws cov ntsiab lus tseem ceeb yog qhov zoo ib yam: lub zog siab ceev, lub neej ntev, lub peev xwm ceev ceev thiab kev tso tawm, qhov kub thiab txias ntau yam hloov tau, thiab kev nyab xeeb ntawm sab hauv. Txawm li cas los xij, hauv kev siv tswv yim, cov kev cai no feem ntau ntsib ntau yam teeb meem. Piv txwv li, qhov sib npaug ntawm lub zog siab ceev thiab kev nyab xeeb tseem yog ib qho kev sib tw tas li, tshwj xeeb tshaj yog nyob rau hauv siab - tus nqi them thiab tso tawm cov xwm txheej, qhov uas qhov kev pheej hmoo ntawm thermal runaway nce ntau. Nyob rau hauv loj - teev lub zog cia cov tshuab, cov roj teeb pob tsis sib xws tuaj yeem ua rau muaj kev tshaj tawm hauv zos lossis tshaj - tawm, yog li cuam tshuam rau tag nrho lub neej. Tsis tas li ntawd, kev tswj qhov kub thiab txias thiab kev saib xyuas hauv cov cheeb tsam nyuaj tseem yog cov ntsiab lus mob hauv kev lag luam.
Txhawm rau daws cov teeb meem no, cov kev daws teeb meem tam sim no tau hloov pauv los ntawm kev ua kom zoo ntawm tus kheej cov khoom rau kev tsim qauv. Los ntawm kev sib koom ua ke nrog ntau yam txuj ci xws li cov ntaub ntawv tshawb fawb, hluav taws xob hluav taws xob, thiab kev txawj ntse, tag nrho cov kev ua tau zoo ntawm cov roj teeb pob tau maj mam txhim kho.
II. Cov Txheej Txheem Txheej Txheem Tseem Ceeb thiab Cov Lus Qhia Txog Kev Tsim Kho Tshiab
1. Iteration of the Intelligent Management System (BMS)
Lub roj teeb tswj system (BMS) ua haujlwm raws li "lub hlwb" ntawm lub roj teeb pob. Nws cov haujlwm tau nthuav dav los ntawm qhov yooj yim voltage, tam sim no, thiab ntsuas qhov kub thiab txias mus rau SOC (State of Charge) thiab SOH (Lub Xeev Kev Noj Qab Haus Huv) kwv yees, nrog rau kev ntsuas dynamic ntsuas. Tom ntej no - tiam BMS siv siab - qhov tseeb sensors thiab ntau -dimensional algorithms los kwv yees cov roj teeb hauv lub sijhawm, txheeb xyuas cov kev pheej hmoo ua ntej, thiab txuas ntxiv lub neej tag nrho ntawm lub roj teeb pob los ntawm kev sib npaug. Tsis tas li ntawd, AI-raws li cov qauv kev txheeb xyuas cov ntaub ntawv txhim kho kev them nyiaj thiab tso tawm cov tswv yim, txhim kho kev siv hluav taws xob ntxiv.
2. Kev tswj cov cua kub thiab kev tiv thaiv kev nyab xeeb
Thermal tswj yog ib qho tseem ceeb los xyuas kom meej lub roj teeb ruaj khov ua haujlwm. Kev sib xyaw ua ke ntawm cov kua cua txias, cov khoom siv hloov pauv theem (PCM), thiab cov tshuab cua txias cua muab cov kev daws teeb meem kho cua sov kom haum raws li qhov xav tau ntawm cov xwm txheej sib txawv. Piv txwv li, nyob rau hauv lub tsheb hluav taws xob sector, kua cua txias tshuab precisely tswj coolant flow rate thiab kub, xyuas kom meej lub roj teeb pob tuav ib tug tsim nyog kev khiav hauj lwm kub txawm nyob rau hauv huab kev ua hauj lwm tej yam kev mob. Tsis tas li ntawd, kev siv hluav taws kub - cov ntaub ntawv tsis zoo thiab ntau- theem kev tiv thaiv kev nyab xeeb (xws li fuses, relays, thiab software tiv thaiv logic) ua ke tsim ntau yam - txheej tiv thaiv kev nyab xeeb.
3. Modular thiab Standardized Design
Txhawm rau ua kom tau raws li qhov xav tau ntawm cov kev xav tau sib txawv ntawm cov ntawv thov sib txawv, cov khoom siv roj teeb tau hloov mus rau kev hloov pauv. Standardized cell thiab module tsim kom muaj kev sib dhos sai ntawm cov roj teeb pob nrog ntau qhov sib txawv thiab qib voltage, txo cov nqi tsim khoom thiab kev saib xyuas. Tsis tas li ntawd, cov txheej txheem kev sib txuas lus sib koom ua ke (xws li CAN thiab BMS-CAN) ua kom cov pob roj teeb tuaj yeem ua ke nrog ntau yam khoom siv, txhim kho kev sib raug zoo.
III. Kev lag luam daim ntawv thov thiab yav tom ntej Trends
Hauv kev lag luam tsheb hluav taws xob, cov roj teeb pob daws teeb meem yog tsav kev sib tw hauv ntau thiab them ceev. Kev sib xyaw ua ke ntawm 800V siab-voltage platform thiab khoom-lub xeev roj teeb thev naus laus zis yuav txhim kho cov neeg siv khoom. Hauv kev lag luam cia lub zog, loj- cov roj teeb loj loj tau ua kom muaj kev sib koom ua ke ntawm cov feem ntau ntawm lub zog tauj dua tshiab los ntawm kev hloov pauv siab tshaj plaws thiab kev tswj hwm kab sib chaws. In the future, with the maturity of new chemistries such as sodium-ion batteries and lithium-sulfur batteries, the energy density and economic efficiency of battery packs are expected to achieve a qualitative leap.
Nyob rau tib lub sijhawm, kev tsim khoom ntsuab thiab rov ua dua tshiab tau dhau los ua qhov tseem ceeb hauv kev lag luam. Los ntawm kev txhim kho cov txheej txheem tsim khoom thiab cov khoom siv thev naus laus zis rov ua dua tshiab, cov pa roj carbon hneev taw ntawm cov pob roj teeb hla lawv lub neej tag nrho yuav txo qis, tsav lub zog tshiab kev lag luam mus rau kev txhim kho kom ruaj khov.
Xaus
Kev txhim kho thev naus laus zis hauv cov kev daws teeb meem roj teeb tsis tsuas yog txhim kho kev ua tau zoo ntawm cov khoom siv ib leeg xwb tab sis kuj tseem muab kev txhawb nqa tseem ceeb rau kev ua tiav lub zog hloov pauv thiab cov hom phiaj ntawm cov pa roj carbon nruab nrab. Nyob rau hauv lub neej yav tom ntej, nrog rau kev sib sib zog nqus ntawm ntoo khaub lig- kev qhuab qhia technologies thiab tsav los ntawm kev lag luam xav tau, cov roj teeb pob yuav ua tau zoo dua, muaj kev nyab xeeb, thiab ntse dua, muab lub hauv paus ruaj khov rau optimizing lub ntiaj teb lub zog sib xyaw.
