NEVI kev ua raws cai tswj hwm qhov tsawg kawg nkaus ntawm 150kW ib qhov chaw nres nkoj ib txhij. Koj yuav tsum tau hais kom kho vajtse muaj peev xwm ua tau raws li cov theem pib no. Tsis tas li ntawd, kev sib koom ua ke software muaj zog yog qhov yuav tsum tau ua kom muaj txiaj ntsig zoo. Saib rau haiv neeg OCPP 2.0.1 kev txhawb nqa tsim ncaj qha rau hauv kho vajtse. Cov txheej txheem no ua kom muaj kev nyab xeeb ntawm kev tswj xyuas backend thiab txhim khu kev qha kev them nqi. Tsis tas li ntawd, kev ua raws li ISO 15118 ua rau kev ua haujlwm tsis sib haum xeeb thiab them nyiaj. Cov neeg tsav tsheb tsuas yog ntsaws rau hauv lawv lub tsheb kom tso cai them nyiaj.
Kev nqis tes ua thiab kev xa tawm tiag tiag
Kev xa tawm tiag tiag hauv ntiaj teb feem ntau ntsib teeb meem kev ua haujlwm zais. Cov tswv tsev yuav tsum taug kev tso cai, nqi zog, thiab kev hloov pauv thev naus laus zis kom zoo. Kev npaj rau cov kev pheej hmoo no tiv thaiv kev puas tsuaj rau txoj haujlwm qeeb.
Kev sib txuas ntawm Bottlenecks
Grid interconnections dictate project ncua sij hawm yuav luag tag nrho. Tsiv los ntawm ntau chav tsev 120kW qhov chaw mus rau ntau chav tsev 360kW qhov chaw ntsuas koj cov kev xav tau siv hluav taws xob loj heev. Kev tso cai thiab kev tshuaj xyuas engineering ncab los ntawm lub lis piam mus rau ob peb lub hlis. Cov khoom siv hluav taws xob yuav tsum ntsuas qhov cuam tshuam hauv cheeb tsam ntawm kab sib chaws ua ntej pom zoo rau kev sib txuas siab. Trenching los ntawm cov pob zeb uas twb muaj lawm ntxiv cov nqi loj heev. Kev ruaj ntseg easements yuav siv sij hawm ntau lub hlis ntawm kev sib tham raws cai. Koj yuav tsum muab cov sij hawm ua ntev ntev no rau hauv koj lub sijhawm xa mus. Tsis quav ntsej txog kev sib txuas lus qeeb ua rau muaj kev ntxhov siab rau qhov project.
Utility Demand Charges
Kev ua haujlwm tau txais txiaj ntsig tso ncaj qha rau kev tswj hwm cov nqi hluav taws xob. Cov cuab yeej siv hluav taws xob siab qhia txog cov khoom siv hluav taws xob loj uas xav tau kev pheej hmoo. Cov nqi hluav taws xob nqi hluav taws xob ua lag luam raws li qhov siab tshaj plaws lub zog kos thaum lub sij hawm them nqi. Xav txog kev lag luam tariffs tshaj $20 ib kilowatt. Ib chav tsev 360kW tau ntsib luv luv, kev siv tsis txaus ntseeg tau ua rau cov nqi xav tau loj heev. Cov nqi no tuaj yeem so tam sim ib hlis ntawm cov nyiaj tau los. Koj yuav tsum txheeb xyuas cov nqi hluav taws xob hauv zos kom zoo zoo. Ua raws li cov kev tswj xyuas cov khoom siv txawj ntse pab txo cov nqi siab tshaj no.
400V vs. 800V Hloov pauv
Kev lag luam automotive yog tsiv mus rau qhov siab dua voltage architectures. Txawm li cas los xij, qhov kev hloov pauv nthuav tawm lub sijhawm nyuaj txaus ntshai. Feem ntau cov tsheb tam sim no siv 400V architectures. Cov tsheb no tau them tus nqi ntawm 150kW txog 200kW. Kev nqis peev ntau dhau ntawm 360kW kho vajtse niaj hnub no tawm qhov muaj peev xwm tsis siv. Koj pheej hmoo stranding peev thaum tos 800V tsheb los ua lag luam. Koj yuav tsum soj ntsuam cov tsheb hauv zos kom meej. Kev xa tawm yooj yim, kho vajtse modular tso cai rau koj hloov kho lub zog modules tom qab. Lub tswv yim no sib npaug qhov kev thov tam sim no tiv thaiv kev hloov pauv thev naus laus zis yav tom ntej zoo nkauj.
