Txoj Cai Ua Haujlwm ntawm DC Charging Piles rau Cov Tsheb Hluav Taws Xob Tshiab

1. Kev faib tawm ntawm pawg them nyiaj

CovAC charging pawgxa cov hluav taws xob AC los ntawm daim phiaj hluav taws xob mus rauthem nyiaj modulentawm lub tsheb los ntawm cov ntaub ntawv sib cuam tshuam nrog lub tsheb, thiab covthem nyiaj modulentawm lub tsheb tswj lub zog kom them cov roj teeb hluav taws xob los ntawm AC rau DC.

CovAC charging phom (Type1, Type2, GB / T) rauAC them chaw nres tshebmuaj 7 qhov dav hlau qhov, 7 qhov muaj hlau terminals los txhawb peb-theemAC fais fab tsheb them chaw nres tsheb(380V), 7 qhov tsuas muaj 5 qhov nrog hlau terminals yog ib-theemAC ev charger(220V), AC them phom me duaDC them phom (CCS1, CCS2, GB / T, Chademo).

CovDC charging pawghloov AC lub zog ntawm daim phiaj hluav taws xob mus rau hauv DC lub zog kom them lub zog roj teeb ntawm lub tsheb los ntawm kev cuam tshuam nrog lub tsheb nrog cov ntaub ntawv, thiab tswj cov zis hluav taws xob ntawm pawg them raws li tus thawj tswj roj teeb ntawm lub tsheb.

Muaj 9 qhov chaw nres nkoj ntawm DC them phom rauDC them chaw nres tsheb, thiab DC charging phom loj dua AC charging phom.

2. Lub hauv paus ntsiab lus ua haujlwm ntawm DC charging pawg

Nyob rau hauv kev lag luam tus qauv "NB / T 33001-2010: Technical Conditions for Non-on-board Conduction Chargers for Electric Vehicles" muab los ntawm National Energy Administration, nws tau taw qhia tias cov ntsiab lus tseem ceeb ntawmDC ev chargersuav nrog: chav tsev fais fab, chav tswj, chav ntsuas ntsuas, ntsuas qhov sib txuas, lub zog hluav taws xob sib txuas thiab tib neeg lub computer sib cuam tshuam. Lub zog hluav taws xob yog hais txog DC charging module, thiab chav tswj hwm yog hais txog lub them pawg tswj hwm. Raws li cov khoom siv sib xyaw ua ke, ntxiv rau ob lub ntsiab lus ntawm "DC charging module"thiab"charger pawg tswj"tsim cov txheej txheem thev naus laus zis, cov qauv tsim qauv kuj yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm kev tsim kho ntawm tag nrho pawg. "Charging pawg tswj" belongs rau qeb ntawm embedded hardware thiab software technology, thiab "DC charging module" sawv cev rau qhov ua tau zoo tshaj plaws ntawm lub zog hluav taws xob hauv tshuab hluav taws xob hauv AC / DC.

Cov txheej txheem yooj yim ntawm kev them nyiaj yog: thauj khoom DC voltage ntawm ob hnub ntawm lub roj teeb, them lub roj teeb nrog lub siab tsis tu ncua, qhov hluav taws xob ntawm lub roj teeb maj mam thiab maj mam nce, nce mus rau qee qhov, lub roj teeb voltage nce mus txog tus nqi nominal, SoC nce mus txog 95% (rau cov roj teeb sib txawv, sib txawv), thiab txuas ntxiv them lub roj teeb nrog qhov tsis tu ncua voltage thiab tam sim no me me. "Lub zog hluav taws xob nce, tab sis lub roj teeb tsis puv, uas yog, nws tsis puv, yog tias muaj sijhawm, koj tuaj yeem hloov mus rau qhov tam sim no me me los txhawb nws." Txhawm rau kom paub txog cov txheej txheem them nyiaj no, pawg them nyiaj yuav tsum muaj "DC charging module" los muab DC lub zog raws li kev ua haujlwm; Nws yog ib qho tsim nyog yuav tsum muaj "them pawg tswj hwm" los tswj "kev siv hluav taws xob, kaw, tso zis hluav taws xob, thiab cov khoom tso tawm tam sim no" ntawm lub charger module; Nws yog ib qho tsim nyog yuav tsum muaj "kov screen" raws li tib neeg-tshuab interface los tawm cov lus qhia, thiab tus maub los yuav muab cov lus qhia xws li "hwj chim rau, kaw, tso zis voltage, tso zis tam sim no" thiab lwm cov lus qhia rau lub charger module. Qhov yooj yim tshaj plaws hluav taws xob tsheb them pawgnkag siab los ntawm qib hluav taws xob tsuas yog yuav tsum muaj lub them nyiaj module, tswj lub rooj tsavxwm thiab kov npo; Yog hais tias cov lus txib xws li lub hwj chim rau, kaw thiab tso zis voltage] cov zis tam sim no tau ua rau hauv ob peb lub keyboards ntawm lub charger module, ces lub charging module tuaj yeem them lub roj teeb.

Covhluav taws xob ib feem ntawm DC chargermuaj ib tug thawj Circuit Court thiab ib tug thib ob Circuit Court. Cov tswv yim ntawm lub voj tseem ceeb yog peb-theem alternating tam sim no, uas yog hloov mus rau tam sim no ncaj qha txais tau los ntawm kev them nyiaj module (rectifier module) tom qab lub input circuit breaker thiab AC ntse zog ntsuas, thiab ces txuas lub fuse thiabev charger gunkom them lub tsheb hluav taws xob. Secondary Circuit Court muaj xws li ahluav taws xob tsheb them pawgmaub los, daim npav nyeem ntawv, lub vijtsam zaub, DC 'meter', thiab lwm yam. Lub teeb liab teeb muab "standby", "them" thiab "tag nrho" cov xwm txheej qhia; Raws li ib tug tib neeg-lub computer kev sib cuam tshuam ntaus ntawv, cov zaub muab daim npav swiping, them hom teeb tsa thiab pib-nres tswj kev ua haujlwm.

Lub hauv paus ntsiab lus hluav taws xob ntawm DC charging pawg tau sau tseg raws li hauv qab no:

• Ib qho kev them nyiaj ib zaug tam sim no tsuas yog 15kW, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog, thiab yuav tsum muaj ntau lub qauv them nyiaj ua haujlwm ua ke ua ke, thiab yuav tsum muaj lub npav CAN kom ua tiav tam sim no sib koom ntawm ntau lub modules;
• Lub tswv yim ntawm lub charger module los ntawm daim phiaj hluav taws xob, uas yog lub zog hluav taws xob siab, nrog rau lub zog hluav taws xob thiab kev nyab xeeb ntawm tus kheej, tshwj xeeb tshaj yog kev nyab xeeb ntawm tus kheej, nws yog ib qho tsim nyog yuav tsum tau nruab ib lub tshuab hluav taws xob hloov hluav taws xob (lub npe scientific yog "plastic plhaub Circuit Court breaker"), hluav taws xob tiv thaiv hluav taws xob hloov lossis txawm tias qhov hloov pauv ntawm cov tswv yim kawg;
• Cov khoom tso tawm ntawm cov khoom siv hluav taws xob muaj hluav taws xob siab thiab siab tam sim no, lub roj teeb yog electrochemical, yooj yim tawg, tiv thaiv kev nyab xeeb ntawm kev ua haujlwm tsis zoo, cov zis yuav tsum muaj fuse;
• Cov teeb meem kev nyab xeeb yog qhov tseem ceeb tshaj plaws, ntxiv rau cov kev ntsuas ntawm qhov kawg ntawm cov khoom siv, cov tshuab ntsuas hluav taws xob thiab cov ntsuas hluav taws xob yuav tsum muaj tam sim no, kev ntsuas hluav taws xob rwb thaiv tsev yuav tsum muaj tam sim no, thiab kev tawm tsam yuav tsum muaj;
• Txawm hais tias lub roj teeb lees txais kev them nyiaj tsis yog txiav txim los ntawm pawg them, tab sis los ntawm lub hlwb ntawm lub roj teeb, BMS. BMS teeb meem cov lus qhia rau tus maub los ntawm "seb puas yuav tso cai rau kev them nyiaj, seb puas yuav txiav tawm kev them nyiaj, qhov hluav taws xob ntau npaum li cas thiab tam sim no tuaj yeem txais tau", thiab tus maub los tom qab ntawd teeb tsa nws mus rau qhov them nyiaj. Yog li ntawd, nws yog ib qho tsim nyog los siv CAN kev sib txuas lus ntawm tus maub los thiab BMS, thiab CAN kev sib txuas lus ntawm tus maub los thiab tus them module;
• Cov pawg them nyiaj kuj yuav tsum tau saib xyuas thiab tswj xyuas, thiab tus maub los yuav tsum tau txuas nrog keeb kwm yav dhau los ntawm WiFi lossis 3G / 4G thiab lwm yam kev sib txuas lus network;
• Daim nqi hluav taws xob rau kev them nyiaj tsis pub dawb, thiab ib lub 'meter' yuav tsum tau teeb tsa, thiab daim npav nyeem ntawv yuav tsum paub txog cov nqi them nqi;
• Yuav tsum muaj lub teeb qhia meej meej ntawm lub plhaub plhaub, feem ntau yog peb lub teeb qhia, uas qhia txog kev them nqi, kev ua txhaum thiab kev siv hluav taws xob raws li;
• Cov pa hluav taws xob tsim ntawm DC charging pawg yog qhov tseem ceeb. Ntxiv nrog rau kev paub txog kev tsim qauv, kev tsim cov pa cua yuav tsum muaj lub kiv cua los nruab rau hauv pawg them nyiaj, txawm hais tias muaj kiv cua hauv txhua qhov kev them nyiaj.
