Ikibazo cya sisitemu ya 800V: gusharija igice cyo gushyushyamo sisitemu

800V charger pile "Ibintu by'ibanze byo charger"

Iyi nkuru ivuga cyane cyane ku bisabwa mbere na mbere kuri 800Vimirundo yo gusharija, reka tubanze turebe ihame ryo gusharija: Iyo agace ko gusharija gahujwe n'inyuma y'ikinyabiziga, agace ko gusharija gatanga (1) ingufu nke za DC ku mpera y'ikinyabiziga kugira ngo gakoreshe BMS yubatswe (sisitemu yo gucunga bateri) y'ikinyabiziga cy'amashanyarazi. Nyuma yo gukoresha, (2) huza impera y'ikinyabiziga n'inyuma y'ikinyabiziga, uhindure ibipimo by'ibanze byo gusharija nk'imbaraga ntarengwa zo gusharija z'inyuma y'ikinyabiziga n'imbaraga ntarengwa zo gutanga umusaruro w'inyuma y'ikinyabiziga, nyuma y'uko impande zombi zihuye neza, BMS (sisitemu yo gucunga bateri) y'inyuma y'ikinyabiziga izohereza amakuru yo gusharija kusitasiyo yo gusharija imodoka za elevator, kandiikirundo cyo gusharija imodoka zikoresha amashanyaraziizahindura ingufu zayo zisohoka n'umuvuduko w'amashanyarazi hakurikijwe aya makuru, kandi itangire gusharija imodoka ku mugaragaro, ari na ryo hame ry'ibanze ryaguhuza gusharija, kandi tugomba kubanza kubimenya.

Gushaja 800V: "kongera amashanyarazi cyangwa umuriro"

Mu buryo bw'imitekerereze, niba dushaka gutanga imbaraga zo gusharija kugira ngo tugabanye igihe cyo gusharija, ubusanzwe hari uburyo bubiri: kongera bateri cyangwa kongera voltage; Dukurikije W=Pt, niba imbaraga zo gusharija zikuba kabiri, igihe cyo gusharija kizagabanuka kimwe cya kabiri; Dukurikije P=UI, niba voltage cyangwa amashanyarazi yikuba kabiri, imbaraga zo gusharija zishobora kwikuba kabiri, ibyo bikaba byaravuzwe kenshi kandi bifatwa nk'ubwenge busanzwe.

Niba umuriro ari munini, hazabaho ibibazo bibiri, uko umuriro uba munini, ni ko insinga irushaho kuba nini kandi nini isaba umuriro, ibyo bikazongera umurambararo n'uburemere bw'insinga, bikongera ikiguzi, kandi ntibikorohera abakozi kuwukoresha; Byongeye kandi, nk'uko Q=I²Rt ibivuga, niba umuriro uri hejuru, igihombo cy'amashanyarazi kiba kinini, kandi igihombo kigaragara mu buryo bw'ubushyuhe, ibyo bikaba byongera umuvuduko w'ubushyuhe, bityo nta gushidikanya ko atari byiza kongera imbaraga zo gusharija ukomeza kongera umuriro, waba usharija cyangwa sisitemu yo gutwara imodoka.

Ugereranyije no gusharija vuba cyane kw'amashanyarazi,gusharija vuba cyane hakoreshejwe voltage nyinshibitanga ubushyuhe buke kandi bigatakaza igihombo gito, kandi amasosiyete y’imodoka hafi ya yose yahisemo inzira yo kongera ingufu z’amashanyarazi, mu gihe cyo gusharija vuba cyane, mu buryo bw’imitekerereze igihe cyo gusharija gishobora kugabanywaho 50%, kandi kwiyongera kwa ingufu z’amashanyarazi bishobora kongera byoroshye imbaraga zo gusharija kuva kuri 120KW kugera kuri 480KW.

Gushyushya 800V: “Ingaruka z'ubushyuhe zijyanye n'amashanyarazi n'umuyoboro w'amashanyarazi”

Ariko byaba ari ukongera voltage cyangwa kongera amashanyarazi, mbere ya byose, uko imbaraga zawe zo gusharija ziyongera, ubushyuhe bwawe buzagaragara, ariko ubushyuhe bwo kongera voltage no kongera amashanyarazi buratandukanye. Ariko, iya mbere niyo nziza ugereranije.

Bitewe n'ubudahangarwa buke bw'umuyoboro w'amashanyarazi iyo unyuze mu muyoboro w'amashanyarazi, uburyo bwo kongera voltage bugabanya ingano y'insinga isabwa, kandi ubushyuhe bugomba gukurwaho buba buke, kandi mu gihe umuyoboro w'amashanyarazi wiyongera, kwiyongera k'agace gatwara umuriro gatuma umurambararo w'inyuma uba munini kandi uburemere bw'insinga bube bwinshi, kandi ubushyuhe buziyongera buhoro buhoro uko igihe cyo gushyushya cyagenda cyongerwa, kikaba cyihishe cyane, ibyo bikaba ari ingaruka zikomeye kuri bateri.

Gushaja 800V: “Hari ibibazo byihutirwa mu bijyanye no gushaja ibyuma”

Gushaja vuba bya 800V bifite ibisabwa bitandukanye ku mpera y'ikirundo:

Iyo urebye mu buryo bufatika, hamwe n’ubwiyongere bw’amashanyarazi, ingano y’imiterere y’ibikoresho bifitanye isano igiye kwiyongera, urugero, hakurikijwe urwego rw’umwanda rwa IEC60664 ari 2 kandi intera y’itsinda ry’ibikoresho byo gukingira ari 1, intera y’igikoresho gifite ingufu nyinshi igomba kuba kuva kuri 2mm kugeza kuri 4mm, kandi ibisabwa ku buryo bwo kwirinda gukingira umuriro nabyo biziyongera, hafi intera yo gucikamo ibice n’ibisabwa ku gukingira umuriro bigomba gukuba kabiri, bigomba kuvugururwa mu gishushanyo ugereranije n’igishushanyo cya mbere cy’amashanyarazi, harimo imiyoboro y’umuringa, imiyoboro y’amashanyarazi, nibindi. Byongeye kandi, kwiyongera k’amashanyarazi bizatuma habaho ibisabwa byinshi byo kuzimya imiyoboro y’amashanyarazi, kandi ni ngombwa kongera ibisabwa ku bikoresho bimwe na bimwe nka fuse, udusanduku tw’amashanyarazi, imiyoboro y’amashanyarazi, nibindi, binakoreshwa mu gishushanyo cy’imodoka, bizavugwa mu ngingo zikurikira.

Sisitemu yo gusharija ifite voltage nyinshi ya 800V igomba kongeramo sisitemu yo gukonjesha amazi ikora hanze nkuko byavuzwe haruguru, kandi uburyo busanzwe bwo gukonjesha umwuka ntibushobora kuzuza ibisabwa byaba ari ugukonjesha gukora cyangwa kudakora, ndetse no gucunga ubushyuhe bw'amazi.sitasiyo yo gusharija imodoka zikoresha amashanyaraziUmurongo w'imbunda ugana ku mpera y'ikinyabiziga nawo uri hejuru kurusha mbere, kandi uburyo bwo kugabanya no kugenzura ubushyuhe bw'iki gice cy'ikoranabuhanga kuva ku rwego rw'igikoresho n'urwego rwa sisitemu ni cyo kintu kigomba kunozwa no gukemurwa na buri sosiyete mu gihe kizaza; Byongeye kandi, iki gice cy'ubushyuhe si ubushyuhe buterwa no gusharija cyane gusa, ahubwo ni n'ubushyuhe buterwa n'ibikoresho bikoresha ingufu nyinshi, bityo uburyo bwo gukurikirana mu gihe nyacyo no guhoraho, neza kandi mu mutekano mu gukuraho ubushyuhe ni ingenzi cyane, atari iterambere mu bikoresho gusa, ahubwo no kumenya neza uburyo ibintu bikoreshwa, nko kugenzura ubushyuhe mu gihe nyacyo no gukurikirana neza ubushyuhe.

Muri iki gihe, voltage isohoka yaIbirundo byo gusharija bya DCKu isoko muri rusange ni 400V, idashobora gusharija bateri ya 800V mu buryo butaziguye, bityo hakenewe ikindi gicuruzwa cya DCDC cyongera ingufu kugira ngo voltage ya 400V igere kuri 800V, hanyuma isharije bateri, bisaba imbaraga nyinshi no guhinduranya inshuro nyinshi, kandi module ikoresha silicon carbide kugira ngo isimbure IGBT isanzwe niyo mahitamo asanzwe, nubwo module za Silicon carbide zishobora kongera imbaraga zo gusohora ibyuma binini no kugabanya igihombo, ariko igiciro nacyo kiri hejuru cyane, kandi ibisabwa kuri EMC nabyo biri hejuru.

Muri make, kwiyongera k'amashanyarazi bizakenera kongerwa ku rwego rwa sisitemu no ku rwego rw'ibikoresho, harimo sisitemu yo gucunga ubushyuhe, sisitemu yo kurinda gusharija, nibindi, kandi urwego rw'ibikoresho harimo kunoza bimwe mu bikoresho bya rukuruzi n'ibikoresho by'amashanyarazi.
