Hauv cov toj roob hauv pes niaj hnub no ntawm cov tshuab fais fab, kev khaws cia lub zog yog ib qho tseem ceeb uas ua kom muaj kev sib koom ua ke ntawm cov khoom siv hluav taws xob rov ua dua tshiab thiab txhawb nqa kev ruaj khov ntawm lub network. Nws cov ntawv thov suav nrog kev tsim hluav taws xob, kev tswj hwm lub network, thiab kev siv cov neeg siv kawg, ua rau nws yog ib qho thev naus laus zis tseem ceeb. Tsab xov xwm no nrhiav kev soj ntsuam thiab tshuaj xyuas qhov kev faib tawm ntawm tus nqi, qhov xwm txheej kev txhim kho tam sim no, thiab kev cia siab yav tom ntej ntawm cov tshuab khaws cia lub zog roj teeb lithium-ion.
Kev faib tawm tus nqi ntawm cov txheej txheem khaws cia hluav taws xob:
Cov qauv nqi ntawm cov txheej txheem khaws cia hluav taws xob feem ntau muaj tsib yam khoom: cov roj teeb modules, Battery Management Systems (BMS), cov thawv (xws li Power Conversion Systems), cov nqi tsim kho thiab teeb tsa, thiab lwm yam kev tsim qauv thiab kev debugging outtakes. Ua piv txwv 3MW/6.88MWh lub cev khaws cia hluav taws xob los ntawm lub Hoobkas hauv Zhejiang Province, cov roj teeb modules suav txog 55% ntawm tag nrho cov nqi.
Kev Tshawb Fawb Sib Piv ntawm Cov Tshuab Siv Roj Teeb:
Lub tshuab hluav taws xob lithium-ion muaj xws li cov neeg muab khoom siv hluav taws xob sab saud, cov neeg sib koom ua ke nruab nrab, thiab cov neeg siv kawg sab hauv qab. Cov khoom siv suav nrog roj teeb, Cov Tshuab Tswj Hluav Taws Xob (EMS), Cov Tshuab Tswj Hluav Taws Xob (BMS), mus rau Cov Tshuab Hloov Hluav Taws Xob (PCS). Cov neeg sib koom ua ke suav nrog cov neeg sib koom ua ke ntawm lub tshuab khaws hluav taws xob thiab cov tuam txhab Engineering, Procurement, thiab Construction (EPC). Cov neeg siv kawg suav nrog kev tsim hluav taws xob, kev tswj hwm grid, kev siv cov neeg siv kawg, thiab kev sib txuas lus / chaw khaws ntaub ntawv.
Cov nqi ntawm Lithium-ion roj teeb:
Cov roj teeb lithium-ion ua haujlwm ua cov khoom tseem ceeb ntawm cov txheej txheem khaws cia hluav taws xob electrochemical. Tam sim no, kev ua lag luam muaj ntau yam thev naus laus zis roj teeb xws li lithium-ion, lead-carbon, flow batteries, thiab sodium-ion batteries, txhua tus muaj lub sijhawm teb sib txawv, kev ua haujlwm ntawm lub zog tawm, thiab cov txiaj ntsig thiab qhov tsis zoo uas tsim tshwj xeeb.
Cov nqi ntawm cov roj teeb yog feem ntau ntawm cov nqi tag nrho ntawm cov khoom siv khaws cia hluav taws xob electrochemical, suav txog li 67%. Cov nqi ntxiv suav nrog cov inverters khaws cia hluav taws xob (10%), cov txheej txheem tswj roj teeb (9%), thiab cov txheej txheem tswj hluav taws xob (2%). Hauv qhov nqi ntawm cov roj teeb lithium-ion, cov khoom siv cathode thov qhov feem ntau ntawm kwv yees li 40%, tom qab ntawd yog cov khoom siv anode (19%), electrolyte (11%), thiab separator (8%).
Cov Qauv Tam Sim No thiab Cov Teeb Meem:
Txij li xyoo 2023 los, tus nqi ntawm cov roj teeb cia hluav taws xob tau poob qis vim yog tus nqi ntawm lithium carbonate txo qis. Kev siv cov roj teeb lithium iron phosphate hauv kev lag luam cia hluav taws xob hauv tsev tau ua rau tus nqi txo qis ntxiv. Ntau yam khoom siv xws li cov ntaub ntawv cathode thiab anode, separator, electrolyte, current collector, cov khoom siv hauv tsev, thiab lwm yam tau pom kev hloov pauv tus nqi vim yog cov yam no.
Txawm li cas los xij, kev lag luam roj teeb cia hluav taws xob tau hloov pauv ntawm qhov tsis txaus mus rau qhov xwm txheej ntau dhau, ua rau kev sib tw nce ntxiv. Cov neeg nkag los ntawm ntau yam kev lag luam, suav nrog cov chaw tsim roj teeb fais fab, cov tuam txhab photovoltaic, cov tuam txhab roj teeb cia hluav taws xob tshiab, thiab cov kws tshaj lij hauv kev lag luam, tau nkag mus rau hauv kev sib tw. Qhov kev nkag los no, ua ke nrog cov neeg ua si uas twb muaj lawm cov peev xwm nthuav dav, ua rau muaj kev pheej hmoo ntawm kev hloov pauv kev lag luam.
Xaus lus:
Txawm hais tias muaj kev cov nyom ntawm kev muaj khoom ntau dhau thiab kev sib tw ntau ntxiv, kev lag luam khaws cia hluav taws xob tseem txuas ntxiv nthuav dav sai. Xav txog tias yog thaj chaw muaj peev xwm muaj peev xwm ntau txhiab lab daus las, nws muaj cov cib fim loj hlob ntau, tshwj xeeb tshaj yog thaum muaj kev txhawb nqa cov cai tswjfwm hluav taws xob rov ua dua tshiab thiab Tuam Tshoj cov lag luam thiab kev lag luam ua lag luam. Txawm li cas los xij, nyob rau theem no ntawm kev muaj khoom ntau dhau thiab kev sib tw loj heev, cov neeg siv khoom hauv qab yuav xav tau cov qauv zoo rau cov roj teeb khaws cia hluav taws xob. Cov neeg nkag tshiab yuav tsum tsim cov teeb meem thev naus laus zis thiab cog qoob loo cov peev xwm tseem ceeb kom vam meej hauv thaj chaw hloov pauv no.
Hauv kev xaus lus, kev ua lag luam hauv Suav teb rau cov roj teeb lithium-ion thiab cov roj teeb khaws cia hluav taws xob muaj ntau yam kev cov nyom thiab cov cib fim. Kev nkag siab txog kev faib tawm tus nqi, cov qauv thev naus laus zis, thiab kev lag luam yog qhov tseem ceeb rau cov tuam txhab uas sim ua kom muaj kev muaj zog hauv kev lag luam uas hloov pauv sai no.
