Yuav Ua Li Cas Xaiv Ib Lub DC EV Charger rau Daim Ntawv Thov Sib Txawv?

 

Cov saw hloov dua siab tshiab yog qhov yooj yim los piav qhia thiab tseem ceeb kom qhia kom raug:

• Daim phiaj noj- peb-theem AC (400 V hauv EU, 480 V hauv North America, 11-33 kV qhov twg lub siab hloov pauv tau teeb tsa).
• Kev kho- lub active pem hauv ntej-kawg rectifier nrog lub hwj chim-factor kho converts AC rau DC. Cov chav nyob niaj hnub khaws cov khoom siv hluav taws xob ntau dua 0.99 thiab tam sim no THD qis dua 5%, uas tseem ceeb yog tias koj qhov chaw siv hluav taws xob txwv IEEE 519 lossis EN 61000 harmonic txwv.
• DC xa khoom- Lub charger sib tham txog qhov voltage thiab tam sim no nrog lub tsheb hla tus tsav tswj (IEC 61851-23 rau DC, IEC 61851-24 rau kev sib txuas lus digital).
• Roj teeb tswj tswj- lub tsheb BMS, tsis yog lub charger, txiav txim siab qhov tseeb tus nqi nkhaus. Qhov no yog ib qho kev saib tsis taus tshaj plaws hauv kev yuav khoom.

Vim tias BMS tswj hwm qhov nkhaus, lub charger tus nqi tso zis yog ib qholub hnab ntawv sab saud, tsis muaj guarantee. Nruab nrab ntawm kwv yees li 10% thiab 80% lub xeev ntawm tus nqi, feem ntau cov pob khoom niaj hnub lees txais lawv cov nqi siab tshaj; tshaj 80%, tam sim no tapers sharply. Tias yog vim li cas kev lag luam luam tawm "10-80%" lub sij hawm thiab vim li cas qhov kev sib piv ncaj ncees metric yogkWh xa tuaj rau ib teev ntawm qhov chaw nyob, tsis muaj zog kW.

   

 

Cov chav kawm fais fab raug cai ua raws li daim ntawv thov. Cov lus hauv qab no suav nrog cov khoom siv loj siv los ntawm cov neeg ua haujlwm pej xeem, cov chaw tsim khoom, thiab cov neeg tsim kev loj hauv xyoo 2026.

Daim ntawv thov them nqi	Pom zoo DC charger fais fab	Hom connector teeb	Main tsim tsav tsheb
Nroog pej xeem them hub	60-150 kW	CCS2 + CHAdeMO or CCS1 + NACS	Kev siv tsheb thauj mus los thiab kev siv bay
Qhov chaw pabcuam kev loj / so nres	150-350 kW	CCS2 (kua-txias saum 200 A)	Yam tsawg kawg nyob hauv lub sijhawm, kab ntev

Fleet sizing, ua haujlwm kawg.Nees nkaum hluav taws xob xa hluav taws xob, txhua qhov rov qab nrog kwv yees li 40 kWh ntawm kev xav tau lub zog txhua hnub, xav tau 800 kWh ib hmos. Nrog rau yim-teev them lub qhov rais, qhov theoretical nruab nrab lub zog yog 800 ÷ 8 =100 kW. Ntxiv kev poob qis (feem ntau yog 5-8% ntawm lub zog no) thiab cov paj rau lub caij ntuj no, thiab a120-150 kW kev teeb tsayog cov lus teb tiv thaiv - tsis yog 300 kW chav tsev, thiab tsis yog kaum 20 kW lub thawv ib yam.

Connector xaiv yog qhov teeb meem geography disguised raws li qhov teeb meem engineering. Tau txais nws tsis ncaj ncees lawm thiab lub xaib raug tso tseg.

Txuj	Cov lag luam tseem ceeb	Hom DC lub zog	2026 xwm
CCS2 (Combo 2)	EU, UK, feem ntau ntawm Asia, Oceania	mus txog 350 kW (kua-txias txog 500 A)	Default rau pej xeem infrastructure tshiab

Ob qhov tshwj xeeb tshaj qhov ntsaws nws tus kheej tsim nyog cov kab lus meej hauv koj RFQ:

• Output voltage qhov rais.800 V tsheb platforms yog tam sim no mainstream. Lub charger txwv rau 500 V DC tsuas yog tsis tuaj yeem pab lawv ntawm tus nqi tag nrho. Qhia meej a150-1000V DC tso zis ntau yamtshwj tsis yog tias koj lub nkoj yog tag nrho 400 V.
• Backend raws tu qauv.Insist rauPAB 1.6Jraws li pem teb thiabOCPP 2.0.1Yog tias koj npaj them tus nqi ntse, ISO 15118 Plug & Charge, lossis cov tsav tsheb-rau-daim phiaj. Yog tsis muaj OCPP koj raug kaw rau ib tus neeg muag khoom software rau lub neej ntawm cov cuab tam.

 

Qhov no yog ntu feem ntau charger yuav cov lus qhia hla, thiab nws yog qhov project ua tsis tau. Lub chaw them nyiaj DC ceev ceev yog ib qhofais fab tuag qhov project nrog lub charger txuas, thiab transformer, switchgear, thiab faib txee feem ntau yog 20-35% ntawm tag nrho cov capex.

 

Txoj kev sizing, step by step:

Xam qhov ntsuas AC input ntawm tag nrho cov chargers: charger kW ÷ efficiency ÷ fais fab tuag.

Multiply amuaj ntau haiv neeg- 0.6–0.8 rau depots nrog ntev, teem caij tsheb qhov rais; 0.85–1.0 rau qhov chaw loj uas tuaj txog yog random thiab ncov stacking yog tiag tiag.

 

Ntxiv qhov chaw thauj khoom: teeb pom kev zoo, HVAC, kev them nyiaj kiosks, canopy, thiab cov khoom siv hauv chav ua haujlwm (feem ntau 10-20 kVA).

Xaiv tus qauv ntsuas tom ntej saum toj no qhov tshwm sim, tom qab ntawd tshawb xyuas qhov hluav taws xob poob ntawm 400 V khiav thiab qhov kev xav tau luv luv tam sim no ntawm pawg thawj coj faib khoom.

 

Piv txwv li ua hauj lwm - fleet depot, rau 120 kW dual-phom chargers:

• AC input ib lub charger: 120 ÷ 0.95 ÷ 0.99 ≈126 kVA
• Tag nrho ib txhij load: 6 × 126 =758 kVA
• Nrog 0.7 ntau haiv neeg (lub qhov rais hmo ntuj, dynamic load tswj nquag):531 kVA
• Site auxiliary loads:+25 kVA → 556 kVA
• Xaiv: 630 kVA qhuav-hom transformer, 11 kV / 0.4 kV, Dyn11, IEC 60076

 

Ua hauj lwm piv txwv - txoj kev loj hub, rau 240 kW chargers:

• AC input ib lub charger: 240 ÷ 0.95 ÷ 0.99 ≈252 kVA
• Gross simultaneous load:1,512 kVA
• Nrog 0.8 ntau haiv neeg:1,210 kVA
• Site auxiliary loads:+40 kVA → 1,250 kVA
• Xaiv: 1,600 kVA cam khwb cia-resin lossis roj-immersed transformer, nrog rau 2,000 kVA chav tsev yog npaj rau theem ob

 

Ob daim phiaj-sab ntxiv checks ib txwm tsis tau:

• Harmonics thiab flicker.Rau-pulse rectifiers yam tsis muaj PFC nquag tuaj yeem ua txhaum cai txwv kev siv hluav taws xob. Yuav tsum tau ntsuas THD cov ntaub ntawv ntawm ib nrab load, tsis yog ntawm tag nrho cov load - ib nrab load yog qhov twg ntau units coj phem tshaj.
• Derating rau qhov chaw tej yam kev mob.Tshaj 1,000 m qhov siab lossis 40℃ambient, ob qho tib si chargers thiab transformers derate. Ib qhov chaw nyob hauv qhov chaw kub, qhov chaw siab siab tuaj yeem poob 10-15% ntawm cov khoom siv tau, thiab qhov ntawd yuav tsum yog nyob rau hauv cov lus qhia tshwj xeeb, tsis pom ntawm commissioning.

 

 

Hardware feem ntau yog ib nrab ntawm zaj dab neeg. Ib tug qauv tsib xyoos muaj tiag muaj xws li:

• Charger kho vajtse- thiab delta ntawm huab cua-txias thiab kua-txias yog qhov tseem ceeb.
• Daim phiaj-sab khoom siv- transformer, MV / LV switchgear, faib txee, cabling, earthing, civil ua hauj lwm.
• Installation thiab commissioning- suav nrog txhua qhov kev pab cuam siv hluav taws xob.
• Software thiab kev sib txuas- OCPP backend, them nyiaj davhlau ya nyob twg, SIM / cov ntaub ntawv, PCI-DSS scope yog tias koj them daim npav.
• Zog- ntshuam tariff, thov nqi, thiab tus nqi ntawm load tswj nyob rau hauv shaving peaks.
• Kev tu thiab tu lub sijhawm- qhov chaw pej xeem ntawm 95% uptime piv rau 99% uptime yog cov khoom siv nyiaj tau los sib txawv thaum bay-teev yog koj cov khoom.
• Kev nthuav dav- qhov seem seem, qhov muaj peev xwm hloov pauv hloov pauv, thiab cov khoom seem tawg yog pheej yig ntawm theem tsim thiab kim tom qab.

 

Npaj nthuav qhia meej. Khaws cia20-30% ntawm lub taub haunyob rau hauv transformer muaj peev xwm thiab ducting ntawm thawj theem. Paub meej tias cov kab sib txuas uas twb muaj lawm tuaj yeem nqa tau theem thib ob, xyuas tias lub charger txhawb kev faib hluav taws xob muaj zog yog li ntxiv cov chav nyob sib koom ib lub hnab ntawv ruaj khov, thiab txheeb xyuas cov khoom sib txuas thiab cov txheej txheem tiv thaiv cov tsheb uas koj xav kom yuav hauv peb xyoos - tsis yog cov uas koj muaj hnub no.

 

Ib tug RFQ, ib lub luag haujlwm tog.Cov neeg muag khoom thiab cov khoom siv hluav taws xob sib txuas lus sib cais yog qhov feem ntau ntawm kev tsis sib haum xeeb ntawm kev them nyiaj - lub transformer tuaj txog rau qhov kev xav ntawm ntau haiv neeg, lossis lub txee faib khoom tsis muaj txoj hauv kev tawg rau theem ob. Bundle lub transformer, switchgear, thiab faib txee rau hauv ib qho kev nug nrog koj lub charger specification txuas, thiab qhov kev pheej hmoo cuam tshuam yuav ploj mus.
