Raws li kev hloov pauv hluav taws xob thoob ntiaj teb nrawm dua thiab xav tau rau cov chaw ua lag luam txawv teb chaws, chaw them nqi, thiab cov kab hluav taws xob microgrids tseem nce ntxiv, kev sib koom ua ke ntawm photovoltaic-storage-charging systems tau tshwm sim los ua ib qho kev xaiv nrov hauv kev lag luam thoob ntiaj teb vim lawv cov kev sib koom ua ke siab, kev xa mus sai, thiab kev hloov pauv dav dav. Tsis ntev los no, Xiehang Energy tus kheej tsim 261kWh kev koom ua ke PV-storage-them txee tau ua tiav kev ua lag luam tseem ceeb, ua kom muaj ntau yam kev txiav txim txawv teb chaws. Cov khoom lag luam leverages nws tus tswv EMS (Energy Management System) kom muaj kev sib koom tes ntse ntawm cov khoom siv hluav taws xob photovoltaic, lub zog cia, thiab them cov khoom thauj, ua kom ruaj khov thiab txhim khu kev lag luam hauv cov xwm txheej nyuaj-tau txais kev lees paub los ntawm cov neeg siv khoom thoob ntiaj teb.
Ib qho kev sib tw tseem ceeb hauv kev khiav hauj lwm kev sib koom ua ke ntawm PV-storage-charging systems yog nyob rau hauv qhov tsis sib xws ntawm lub hnub ci zog thiab cov qauv random load ntawm lub tsheb fais fab. Thaum sib xyaw ua ke, cov yam ntxwv no tuaj yeem yooj yim ua rau muaj kev hloov pauv ntawm qhov hluav taws xob thiab lub zog tsis txaus, ua rau muaj kev cuam tshuam hauv lub cev thiab kev tiv thaiv tsis tseeb-tshwj xeeb tshaj yog nyob rau hauv cov phiaj xwm tsis muaj zog, cov kob ib puag ncig, lossis thaj chaw muaj kev lag luam. Los ntawm qhov pib, Xiehang Zog tau tsim nws cov EMS ua lub hauv paus "lub hlwb" ntawm tag nrho cov kab ke, tshem tawm kev cia siab rau kev tswj hwm thib peb. Los ntawm kev sib koom ua ke cov txheej txheem tseem ceeb ntawm qib hauv paus, nws ua rau muaj kev sib koom ua ke tsis sib haum xeeb thoob plaws photovoltaic cov tswv yim, roj teeb them / tawm mus, DC them cov zis tawm, thiab kev sib cuam tshuam hauv kab sib chaws. Tshwj xeeb ua kom zoo rau cov kab sib txawv txawv teb chaws, cov kab ke ua haujlwm tau zoo los daws cov teeb meem kev ruaj ntseg ntev uas tau ntsib los ntawm cov haujlwm thoob ntiaj teb.
Lub 261kWh integrated txee nta ib tug tag nrho pre-fabricated tsim, nrog heev integrated photovoltaic, cia, thiab them units uas debugged thiab sim ua ntej xa zaub mov. Thaum tuaj txog ntawm qhov chaw ua haujlwm, kev teeb tsa thiab kev teeb tsa tuaj yeem ua tiav sai, ua kom lub sijhawm siv sijhawm luv luv thiab txo cov kev siv dag zog ntawm qhov chaw. Lub txee yog nruab nrog A-qib lithium hlau phosphate roj teeb hlwb thiab BMS (Battery Management System) uas txuas ntxiv saib xyuas thiab ntsuas qhov ntsuas hluav taws xob, ntsuas kub, thiab tam sim no hla txhua txoj hlua ntawm tes. Ua ke nrog cov kua-txias thermal tswj kev daws teeb meem, qhov tsim qauv no txo qis roj teeb degradation nyob rau hauv high-temperature, high-humidity, thiab plua plav txawv teb chaws ib puag ncig, ua kom lub neej ntev thiab kev nyab xeeb ntawm kev ua haujlwm. Lub tsev tau dhau ntau daim ntawv pov thawj kev nyab xeeb thoob ntiaj teb, ua tau raws li cov cai nkag mus thoob plaws ntau lub tebchaws thiab cheeb tsam, ua rau nws tsim nyog rau ntau lub khw suav nrog Europe, Southeast Asia, Middle East, thiab Latin America.
Hauv plawv ntawm cov khoom tsim kho tshiab yog Xiehang tus kheej tsim EMS, uas ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob ntse. Ua haujlwm ntawm millisecond-theem zaus, lub kaw lus sau cov ntaub ntawv hauv lub sijhawm ntawm PV tso zis, roj teeb lub xeev-ntawm-tus nqi (SOC), charger fais fab xav tau, thiab daim phiaj voltage / zaus. Nws cia li hloov ntawm ntau lub tswv yim ua haujlwm: thaum lub hnub ci tsim tau txaus, qhov tseem ceeb yog muab rau lub zog hluav taws xob EV, nrog cov khoom siv hluav taws xob ntau ntxiv; Thaum lub hnub ci qis los yog lub sijhawm them siab tshaj plaws, lub roj teeb ntxiv lub zog kom tsis txhob overloading ntawm daim phiaj hauv zos; nyob rau hauv daim phiaj-txuas hom, nws txhawb ncov-valley arbitrage thiab xav tau-sab tswj; thiab nyob rau hauv cov ntaub ntawv ntawm kab sib chaws tsis ua hauj lwm, nws seamlessly hloov mus rau off-grid lag luam, xyuas kom meej uninterrupted fais fab mov rau cov tseem ceeb loads. Tsis tas li ntawd, EMS suav nrog kev ua yuam kev hauv kev twv ua ntej, ua kom paub tseeb txog kev pheej hmoo xws li kev siv hluav taws xob ntau dhau, kev sib txuas lus tsis zoo, lossis qhov sib txawv ntawm qhov kub, ua kom tsis siv neeg lub hwj chim derating thiab tswb-raws li kev tiv thaiv kom tsis txhob muaj kev ruaj ntseg-ua rau nws zoo tagnrho rau cov chaw nres tsheb tsis muaj kev them nyiaj thiab chaw ua si microgrids txawv teb chaws.
Tsis zoo li cov kev daws teeb meem yooj yim kho vajtse, Xiehang's EMS txhawb nqa huab platform kev sib txuas, tso cai rau cov neeg siv khoom txawv teb chaws thiab cov neeg xa khoom tuaj yeem saib xyuas cov cuab yeej ua tau zoo, nkag mus rau cov ntawv ceeb toom hluav taws xob, thiab saib cov lus ceeb toom, nrog rau kev kho cov tswv yim xa tawm hauv online-zoo heev txo tus nqi saib xyuas kev hla ciam teb. Cov pab pawg muaj peev xwm kuj tuaj yeem hloov kho cov tswv yim tswj raws li cov qauv hauv cheeb tsam, cov txheej txheem nqi, thiab cov phiaj xwm phiaj xwm, ua tau raws li cov neeg siv khoom xav tau ntau yam xws li kev siv tus kheej kom zoo, them nyiaj tsim khoom, thiab cov khoom siv hluav taws xob rov qab. Qhov kev txiav txim zaum kawg no suav nrog ntau yam kev siv suav nrog kev lag luam them chaw nres tsheb, cov kob microgrids, thiab lub Hoobkas hluav taws xob ntsuab kev koom ua ke. Cov neeg siv khoom tshwj xeeb muaj nuj nqis rau lub cev muaj peev xwm tswj tau zoo hauv cov kab sib chaws tsis muaj zog thiab kev ua haujlwm yooj yim tau qhib los ntawm EMS.
Lub taub hau txawv teb chaws ntawm Xiehang Energy Storage tau hais tias niaj hnub no, thaum cov neeg siv khoom txawv teb chaws xaiv cov khoom siv hluav taws xob photovoltaic-cia-them (PV-Storage-Charging), lawv tsis tsom rau lub peev xwm thiab tus nqi. Hloov chaw, kev ruaj ntseg hauv lub sijhawm ntev, kev hloov pauv tau yooj yim, thiab kev yooj yim ntawm kev ua haujlwm thiab kev saib xyuas tau dhau los ua cov txheej txheem xaiv tseem ceeb. Tus kheej-tsim EMS (Kev Tswj Xyuas Hluav Taws Xob) yog ib qho ntawm Xiehang qhov zoo tshaj plaws thev naus laus zis, ua kom muaj kev sib sib zog nqus ntawm cov khoom siv thiab kev tswj hwm kom tsis txhob muaj teeb meem kev sib raug zoo thiab kev ruaj ntseg txaus ntshai cuam tshuam nrog kev koom ua ke thib peb. Lub 261 kWh kev koom ua ke PV-Storage-Charging txee yog ib qho qauv tsim hauv Xiehang cov khoom lag luam, ntxiv rau lwm cov qauv xws li 209 kWh PV-Storage-Charging txee, kev lag luam thiab kev lag luam prefabricated lub zog cia ntim, 16 kWh thaj chaw cia khoom siv hluav taws xob, PAY cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. cov khoom siv-npog tag nrho-spectrum daim ntawv thov los ntawm cov khoom siv hluav taws xob hauv tsev thiab lub zog me me thaum muaj xwm txheej ceev mus rau lub tsev kawm ntawv loj thiab chaw nres tsheb microgrids.
Raws li kev lag luam huv huv nyob txawv teb chaws txuas ntxiv mus ntxiv, daim ntawv thov scenarios rau kev sib xyaw PV-Storage-Charging daws yuav txuas ntxiv. Tsiv mus rau pem hauv ntej, Xiehang Zog Cia yuav txuas ntxiv iterate nws EMS algorithms los ntxiv txhim kho daim phiaj kev txhawb nqa muaj peev xwm hauv daim phiaj tsis muaj zog thiab txhim kho hnub ci tus kheej noj cov nqi, thaum tib lub sij hawm ntxiv dag zog rau hauv cheeb tsam kev txhawb nqa thiab kev pab cuam tom qab muag. Kev cia siab rau nws cov khoom siv hluav taws xob sib koom ua ke txhim khu kev qha, lub tuam txhab tsom kom nthuav dav thoob ntiaj teb thiab xa cov kev nyab xeeb, ua haujlwm tau zoo, thiab ntse PV-Storage-Charging lub zog daws teeb meem rau ntau tus neeg siv khoom thoob ntiaj teb, nrawm rau kev xa tawm cov hluav taws xob tauj dua tshiab thoob ntiaj teb.
