1. Taw qhia rau DC charging pawg
Nyob rau hauv xyoo tas los no, kev loj hlob sai ntawm cov tsheb hluav taws xob (EVs) tau tsav qhov kev thov kom muaj txiaj ntsig zoo dua thiab txawj ntse them cov kev daws teeb meem. DC charging pawg, paub txog lawv lub peev xwm them ceev ceev, yog nyob rau ntawm qhov kev hloov pauv no. Nrog kev nce qib hauv thev naus laus zis, cov khoom siv hluav taws xob zoo DC tam sim no tsim los txhim kho lub sijhawm them nyiaj, txhim kho kev siv hluav taws xob, thiab muab kev sib txuas tsis sib haum nrog cov phiajcim ntse.
Nrog rau kev nce ntxiv hauv kev lag luam ntim, kev siv ob-directional OBC (On-Board Chargers) tsis tsuas yog pab txo cov neeg siv khoom kev txhawj xeeb txog ntau yam thiab them kev ntxhov siab los ntawm kev ua kom them sai sai tab sis kuj tso cai rau lub tsheb hluav taws xob ua haujlwm raws li cov chaw cia khoom xa tawm. Cov tsheb no tuaj yeem rov qab fais fab rau hauv kab sib chaws, pab hauv qhov siab tshaj plaws shaving thiab hav filling. Kev them nyiaj zoo ntawm lub tsheb fais fab ntawm DC fast chargers (DCFC) yog ib qho tseem ceeb hauv kev txhawb nqa kev hloov hluav taws xob txuas ntxiv. Ultra-fast charging stations integrates ntau yam khoom xws li cov khoom siv fais fab, sensors, tswj fais fab, thiab kev sib txuas lus. Nyob rau tib lub sijhawm, cov txheej txheem tsim tau yooj yim yuav tsum ua kom tau raws li cov kev xav tau ntawm cov tsheb fais fab sib txawv, ntxiv qhov nyuaj rau kev tsim ntawm DCFC thiab ultra-ceev them chaw nres tsheb.
Qhov sib txawv ntawm AC them thiab DC them, rau AC them (sab laug ntawm daim duab 2), ntsaws OBC rau hauv tus qauv AC qhov hluav taws xob, thiab OBC hloov AC mus rau qhov tsim nyog DC kom them lub roj teeb. Rau DC them nyiaj (sab xis ntawm daim duab 2), cov ntawv them nqi them lub roj teeb ncaj qha.
2. DC charging pawg system muaj pes tsawg leeg
(1) Ua kom tiav cov khoom siv tshuab
(2) System Cheebtsam
(3) Daim duab thaiv kev ua haujlwm
(4) Kev them nyiaj yug pawg subsystem
Theem 3 (L3) DC ceev chargers hla lub on-board charger (OBC) ntawm lub tsheb fais fab los ntawm kev them lub roj teeb ncaj qha los ntawm EV's Battery Management System (BMS). Qhov kev bypass no ua rau muaj kev nce ntxiv hauv kev them nqi ceev, nrog rau cov khoom tso tawm hluav taws xob xws li 50 kW txog 350 kW. Cov zis hluav taws xob feem ntau sib txawv ntawm 400V thiab 800V, nrog cov tshiab EVs trending rau 800V roj teeb tshuab. Txij li thaum L3 DC ceev chargers hloov peb-theem AC input voltage rau hauv DC, lawv siv AC-DC fais fab hloov kho (PFC) pem hauv ntej-kawg, uas suav nrog kev sib cais DC-DC converter. Cov zis PFC no ces txuas mus rau lub tsheb lub roj teeb. Yuav kom ua tiav cov zis hluav taws xob ntau dua, ntau lub zog hluav taws xob feem ntau txuas nrog rau tib lub sijhawm. Qhov txiaj ntsig tseem ceeb ntawm L3 DC ceev chargers yog qhov txo qis hauv lub sijhawm them rau lub tsheb fais fab
Lub charger pawg tub ntxhais yog ib qho yooj yim AC-DC converter. Nws muaj PFC theem, DC tsheb npav thiab DC-DC module

3. Cov txheej txheem them pawg scenario
(1) Optical storage charging system
Raws li lub hwj chim ntawm lub tsheb hluav taws xob tau nce, lub zog xa hluav taws xob ntawm cov chaw them nqi feem ntau tawm tsam kom tau raws li qhov xav tau. Txhawm rau daws qhov teeb meem no, lub chaw khaws khoom siv them nyiaj siv lub tsheb npav DC tau tshwm sim. Lub kaw lus no siv cov roj teeb lithium ua lub zog cia thiab ua haujlwm hauv zos thiab tej thaj chaw deb EMS (Energy Management System) kom sib npaug thiab ua kom zoo dua cov khoom siv thiab kev xav tau ntawm hluav taws xob ntawm daim phiaj, cov roj teeb cia, thiab cov tsheb fais fab. Tsis tas li ntawd, lub kaw lus tuaj yeem yooj yim ua ke nrog cov tshuab hluav taws xob photovoltaic (PV), muab cov txiaj ntsig tseem ceeb hauv cov nqi hluav taws xob thiab cov nqi hluav taws xob off-peak thiab daim phiaj muaj peev xwm nthuav dav, yog li txhim kho kev siv hluav taws xob tag nrho.
(2) V2G them system
Lub tsheb-rau-Grid (V2G) thev naus laus zis siv EV roj teeb los khaws lub zog, txhawb nqa daim phiaj hluav taws xob los ntawm kev ua kom muaj kev sib cuam tshuam ntawm tsheb thiab kab sib chaws. Qhov no txo qhov kev nyuaj siab tshwm sim los ntawm kev sib koom ua ke cov khoom siv hluav taws xob rov ua dua tshiab thiab nthuav dav EV them, thaum kawg txhim kho daim phiaj kev ruaj ntseg. Tsis tas li ntawd, hauv cov cheeb tsam xws li thaj chaw nyob thiab chaw ua haujlwm, ntau lub tsheb hluav taws xob tuaj yeem ua kom zoo dua ntawm cov nqi siab tshaj plaws thiab cov nqi qis tshaj, tswj cov khoom hnyav nce, teb rau daim phiaj xav tau, thiab muab lub zog thaub qab, tag nrho los ntawm centralized EMS (Energy Management System) tswj. Rau cov tsev neeg, Tsheb-rau-Tsev (V2H) thev naus laus zis tuaj yeem hloov EV roj teeb rau hauv cov khoom siv hluav taws xob hauv tsev.
(3) Ordered charging system
Lub kaw lus them nqi feem ntau yog siv cov chaw them nqi ceev ceev, zoo tagnrho rau cov kev xav tau ntau ntxiv xws li kev thauj mus los rau pej xeem, tsheb tavxij, thiab tsheb thauj mus los. Cov sij hawm them nqi tuaj yeem hloov kho raws li hom tsheb, nrog rau kev them nqi thaum lub sijhawm hluav taws xob tsis zoo rau cov nqi qis. Tsis tas li ntawd, ib qho kev tswj hwm kev txawj ntse tuaj yeem siv tau los txhim kho kev tswj hwm hauv nruab nrab ntawm lub nkoj.
4.Kev txhim kho yav tom ntej
(1) Kev sib koom ua ke ntawm kev sib txawv ntawm cov xwm txheej ntxiv los ntawm centralized + faib cov chaw them nqi los ntawm ib qho chaw them nyiaj hauv nruab nrab
Cov chaw nres tsheb them nyiaj raws li qhov chaw yuav ua rau muaj txiaj ntsig ntxiv rau kev txhim kho kev them nyiaj network. Tsis zoo li cov chaw nres tsheb hauv nruab nrab uas cov neeg siv nquag nrhiav cov chargers, cov chaw nres tsheb no yuav koom ua ke rau hauv cov chaw uas tib neeg tau mus xyuas. Cov neeg siv tuaj yeem them lawv lub tsheb thaum lub sijhawm ncua sijhawm (feem ntau tshaj li ib teev), qhov kev them nyiaj ceev tsis yog qhov tseem ceeb. Lub zog them ntawm cov chaw nres tsheb no, feem ntau yog li ntawm 20 mus rau 30 kW, txaus rau cov neeg caij tsheb, muab lub zog tsim nyog kom tau raws li cov kev xav tau yooj yim.
(2) 20kW loj sib koom ua lag luam rau 20/30/40/60kW diversified configuration kev lag luam kev loj hlob
Nrog rau kev hloov mus rau lub zog hluav taws xob ntau dua, muaj qhov xav tau los ua kom qhov siab tshaj plaws ntawm kev them nyiaj ntawm cov pawg them rau 1000V kom haum rau yav tom ntej kev siv cov qauv high-voltage. Qhov kev txav no txhawb nqa cov kev tsim kho tshiab tsim nyog rau cov chaw them nqi. Tus qauv 1000V tso zis hluav taws xob tau txais kev lees paub dav hauv kev lag luam them nyiaj, thiab cov tuam txhab tseem ceeb tau nthuav qhia 1000V high-voltage charging modules kom tau raws li qhov kev thov no.
Linkpower tau mob siab rau muab R&D suav nrog software, kho vajtse thiab zoo li AC / DC fais fab tsheb them pawg rau ntau tshaj 8 xyoo. Peb tau txais ETL / FCC / CE / UKCA / CB / TR25 / RCM daim ntawv pov thawj. Siv OCPP1.6 software, peb tau ua tiav kev sim nrog ntau dua 100 OCPP cov chaw muab kev pabcuam. Peb tau hloov kho OCPP1.6J rau OCPP2.0.1, thiab cov kev lag luam EVSE kev daws teeb meem tau nruab nrog IEC / ISO15118 module, uas yog ib kauj ruam tseem ceeb ntawm kev paub txog V2G bi-directional charging.
Nyob rau hauv lub neej yav tom ntej, cov khoom siv high-tech xws li hluav taws xob tsheb them pawg, hnub ci photovoltaic, thiab lithium roj teeb lub zog cia tshuab (BESS) yuav raug tsim los muab cov kev daws teeb meem siab dua rau cov neeg siv khoom thoob ntiaj teb.
