800V Charging pile "Charging Basics"
Tsab xov xwm no feem ntau tham txog qee qhov kev cai ua ntej rau 800Vcov pawg them nqi, ua ntej cia peb saib lub hauv paus ntsiab lus ntawm kev them: Thaum lub hau them txuas nrog lub tsheb kawg, lub pob them yuav muab (1) lub zog DC qis qis rau lub tsheb kawg kom qhib lub BMS (lub kaw lus tswj roj teeb) ntawm lub tsheb fais fab. Tom qab qhib, (2) txuas lub tsheb kawg rau lub pob them, pauv cov kev teeb tsa them yooj yim xws li lub zog xav tau them siab tshaj plaws ntawm lub tsheb kawg thiab lub zog tso zis siab tshaj plaws ntawm lub pob them, tom qab ob sab sib phim kom raug, BMS (lub kaw lus tswj roj teeb) ntawm lub tsheb kawg yuav xa cov ntaub ntawv xav tau fais fab mus rauchaw them hluav taws xob, thiab covlub tsheb fais fab them nqiyuav kho nws tus kheej lub zog hluav taws xob thiab tam sim no raws li cov ntaub ntawv no, thiab pib them lub tsheb, uas yog lub hauv paus ntsiab lus ntawmkev sib txuas them, thiab peb yuav tsum paub txog nws ua ntej.
800V them: "boost voltage lossis tam sim no"
Hauv kev xav, yog tias peb xav muab lub zog them kom luv lub sijhawm them, feem ntau muaj ob txoj hauv kev: koj nce lub roj teeb lossis nce qhov hluav taws xob; Raws li W = Pt, yog tias lub zog them ob npaug, lub sijhawm them yuav raug txiav ib nrab; Raws li P = UI, yog tias qhov hluav taws xob lossis tam sim no ob npaug, lub zog them tuaj yeem ob npaug, uas tau hais ntau zaus thiab suav tias yog kev nkag siab zoo.
Yog tias qhov tam sim no loj dua, yuav muaj ob qhov teeb meem, qhov loj dua qhov tam sim no, qhov loj dua thiab bulkier lub cable uas xav tau tam sim no, uas yuav ua rau lub xov hlau txoj kab uas hla thiab qhov hnyav nce, ua rau tus nqi nce, thiab tsis yooj yim rau cov neeg ua haujlwm ua haujlwm; Tsis tas li ntawd, raws li Q = I²Rt, yog tias qhov tam sim no siab dua, qhov poob hluav taws xob loj dua, thiab qhov poob tau pom hauv daim ntawv ntawm cua sov, uas kuj ua rau muaj kev nyuaj siab ntawm kev tswj hwm thermal, yog li tsis muaj kev poob siab tias nws tsis yog qhov zoo kom nce lub zog them los ntawm kev nce tam sim no tas li, txawm tias nws yog kev them lossis lub kaw lus tsav tsheb hauv tsheb.
Piv nrog rau kev them ceev ceev tam sim no,kev them ceev ceev high voltagetsim kom muaj cua sov tsawg dua thiab poob qis dua, thiab yuav luag cov tuam txhab tsheb loj tau siv txoj kev nce hluav taws xob, thaum muaj kev them hluav taws xob ceev ceev, lub sijhawm them tuaj yeem luv dua 50%, thiab qhov nce ntawm hluav taws xob kuj tuaj yeem ua rau lub zog them tau yooj yim los ntawm 120KW txog 480KW.
800V them: "Cov teebmeem thermal sib raug rau qhov hluav taws xob thiab tam sim no"
Tab sis txawm tias nws yog nce qhov voltage lossis nce qhov tam sim no, ua ntej tshaj plaws, nrog rau kev nce ntawm koj lub zog them, koj qhov kub yuav tshwm sim, tab sis qhov kev ua kom sov ntawm kev nce qhov voltage thiab nce qhov tam sim no yog txawv. Txawm li cas los xij, qhov qub yog qhov zoo dua piv rau.
Vim tias qhov tsis tshua muaj zog uas tam sim no ntsib thaum hla tus neeg xyuas pib, txoj kev nce voltage txo qhov loj ntawm cov cable uas xav tau, thiab qhov kub uas yuav tsum tau dissipated tsawg dua, thiab thaum tam sim no nce ntxiv, qhov nce ntawm thaj chaw hla tam sim no ua rau muaj qhov loj dua thiab qhov hnyav ntawm cov cable loj dua, thiab qhov kub yuav maj mam nce ntxiv nrog lub sijhawm them ntev dua, uas zais ntau dua, uas yog qhov txaus ntshai rau lub roj teeb.
Kev them 800V: "Qee qhov teeb meem tam sim ntawd nrog cov pawg them"
800V kev them ceev ceev kuj muaj qee qhov kev xav tau sib txawv ntawm qhov kawg ntawm pawg:
Yog tias los ntawm qhov pom ntawm lub cev, nrog rau qhov nce ntawm qhov hluav taws xob, qhov loj me ntawm cov khoom siv cuam tshuam yuav nce ntxiv, piv txwv li, raws li qib kev ua qias tuaj ntawm IEC60664 yog 2 thiab qhov deb ntawm pawg khoom siv rwb thaiv tsev yog 1, qhov deb ntawm lub cuab yeej hluav taws xob siab yuav tsum yog los ntawm 2 hli txog 4 hli, thiab tib yam kev xav tau kev tiv thaiv rwb thaiv tsev kuj yuav nce ntxiv, yuav luag qhov deb ntawm creepage thiab kev xav tau rwb thaiv tsev yuav tsum tau ob npaug, uas yuav tsum tau tsim dua tshiab hauv kev tsim qauv piv rau qhov tsim hluav taws xob yav dhau los, suav nrog cov khoom sib txuas, cov hlau tooj liab, cov khoom sib txuas, thiab lwm yam. Tsis tas li ntawd, qhov nce ntawm qhov hluav taws xob kuj tseem yuav ua rau muaj kev xav tau ntau dua rau kev tua hluav taws xob arc, thiab nws yog qhov tsim nyog los nce qhov kev xav tau rau qee cov khoom siv xws li fuses, hloov thawv, cov khoom sib txuas, thiab lwm yam, uas kuj siv tau rau kev tsim lub tsheb, uas yuav hais hauv cov ntawv tom ntej.
Lub tshuab them hluav taws xob siab 800V yuav tsum ntxiv lub tshuab ua kua txias sab nraud raws li tau hais los saum toj no, thiab cov cua txias ib txwm tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua txawm tias nws yog cua txias nquag lossis tsis nquag, thiab kev tswj hwm thermal ntawmchaw them fais fab tshebTxoj kab phom mus rau qhov kawg ntawm lub tsheb kuj siab dua li ua ntej, thiab yuav ua li cas kom txo thiab tswj qhov kub ntawm qhov no ntawm lub kaw lus los ntawm qib ntaus ntawv thiab qib system yog qhov taw tes uas yuav tsum tau txhim kho thiab daws los ntawm txhua lub tuam txhab yav tom ntej; Tsis tas li ntawd, qhov no ntawm qhov kub tsis yog tsuas yog qhov kub coj los ntawm kev them ntau dhau, tab sis kuj yog qhov kub coj los ntawm cov khoom siv fais fab siab, yog li yuav ua li cas ua qhov kev saib xyuas tiag tiag thiab ruaj khov, zoo thiab muaj kev nyab xeeb kom tshem tawm qhov kub yog qhov tseem ceeb heev, uas tsis yog tsuas yog kev tawg hauv cov ntaub ntawv, tab sis kuj tseem muaj kev tshawb pom, xws li kev saib xyuas tiag tiag thiab zoo ntawm qhov kub them.
Tam sim no, qhov tso zis voltage ntawmDC charging pilesnyob rau hauv kev ua lag luam yog qhov tseeb 400V, uas tsis tuaj yeem them ncaj qha rau lub roj teeb fais fab 800V, yog li ntawd xav tau cov khoom DCDC ntxiv kom nce qhov hluav taws xob 400V mus rau 800V, thiab tom qab ntawd them lub roj teeb, uas xav tau lub zog siab dua thiab kev hloov pauv zaus siab, thiab cov module uas siv silicon carbide los hloov IGBT ib txwm yog qhov kev xaiv tseem ceeb tam sim no, txawm hais tias Silicon carbide modules tuaj yeem ua rau lub zog tso zis ntawm cov pawg them thiab txo qhov poob, tab sis tus nqi kuj siab dua, thiab cov kev cai rau EMC kuj siab dua.
Hauv kev xaus lus, qhov tseem ceeb yog qhov nce ntawm qhov hluav taws xob yuav tsum tau nce ntxiv ntawm theem system thiab theem device, suav nrog thermal management system, charging protection system, thiab lwm yam, thiab theem device suav nrog kev txhim kho qee yam khoom siv magnetic thiab cov khoom siv fais fab.
