800V ikibazo cya sisitemu: Kwishyuza ikirundo cya sisitemu yo kwishyuza

800V Kwishyuza “Kwishyuza Ibyingenzi”

Iyi ngingo ivuga cyane cyane kubisabwa mbere yikirundo cya 800V yumuriro, banza urebe ihame ryo kwishyuza: mugihe umutwe wimbunda wishyuza uhujwe nimpera yimodoka, ikirundo cyumuriro kizatanga ① amashanyarazi make ya DC yingufu zamashanyarazi kumodoka iherezo, kugirango ukoreshe BMS yubatswe (Sisitemu yo gucunga Bateri) yimodoka yamashanyarazi, nyuma yo gukora, end impera yikinyabiziga izahuzwa numurongo wikirundo kugirango uhindure ibipimo fatizo byishyurwa, nkimbaraga nyinshi zisabwa zo kwishyuza ikinyabiziga kirangirira hamwe nimbaraga nini zisohoka zuruhande rwikirundo, kandi impande zombi zizahuza neza.

Nyuma yo guhuza neza, BMS (Sisitemu yo gucunga bateri) kumpera yikinyabiziga izohereza amakuru asaba ingufu kubirundo byumuriro, kandi ikirundo cyumuriro kizahindura ingufu ziva mumashanyarazi hamwe numuyoboro ukurikije aya makuru, hanyuma utangire kwishyuza imodoka, aribyo. ihame ryibanze ryo kwishyuza, kandi birakenewe ko tubanza kubimenyera.

Kwishyuza 800V: “Boost voltage cyangwa current”

Mubyukuri, turashaka gutanga imbaraga zo kwishyuza kugirango tugabanye igihe cyo kwishyuza,mubisanzwe hariho inzira 2: ushobora kuzamura bateri cyangwa kuzamura voltage; ukurikije W = Pt, niba imbaraga zo kwishyuza zikubye kabiri, noneho igihe cyo kwishyuza kizaba kabiri; ukurikije P = UI, niba voltage cyangwa amashanyarazi yikubye kabiri, ingufu zumuriro zirashobora gukuba kabiri, kandi ibi byavuzwe inshuro nyinshi, nabyo bifatwa nkibisanzwe.

Niba umuyoboro uri hejuru, hazabaho ibibazo 2, uko umuyaga uri hejuru, nini na bulkier insinga itwara imiyoboro irakenewe, izamura diameter nuburemere bwinsinga, bizamura igiciro, no kuri gihe kimwe, ntabwo byoroshye ko abakozi bakora; hiyongereyeho, ukurikije Q = I²Rt, niba ikigezweho ari kinini, niko gutakaza ingufu nyinshi, kandi igihombo kigaragarira muburyo bwubushyuhe, nabwo bukongerera igitutu imicungire yubushyuhe, bityo ntagushidikanya ko kwiyongera kwa imbaraga zo kwishyuza ntabwo zifuzwa kumenya iyongerekana ryingufu zumuriro wongera amashanyarazi ubudahwema.kongera ingufu zo kwishyuza ntabwo byifuzwa, haba no kwishyuza cyangwa kuri sisitemu yo gutwara ibinyabiziga.

Ugereranije n’umuriro wihuta cyane, kwishyurwa byihuse cyane bitanga ubushyuhe buke nigihombo gito, kuri ubu, ibigo byimodoka hafi ya byose byafashe inzira yo kongera ingufu za voltage, mugihe habaye amashanyarazi yihuta cyane, mubyukuri, igihe cyo kwishyuza irashobora kugabanywa na 50%, kandi kongera ingufu za voltage birashobora gukururwa byoroshye ingufu zumuriro kuva 120KW kugeza 480KW.

Kwishyuza 800V: “Umuvuduko nubu bihuye ningaruka zumuriro”.

Ariko waba uzamuye voltage cyangwa ikigezweho, mbere ya byose, uko imbaraga zawe zo kwishyiriraho ziyongera, ubushyuhe bwawe buzagaragara, ariko kuzamura voltage hamwe nubushyuhe bwo kwerekana ubushyuhe ntabwo ari bumwe, byihuse zimwe mungaruka kuri bateri ni nanone bike cyane, ugereranije buhoro ariko ubushyuhe bwihishe cyane bigaragara hejuru ntarengwa nabyo biragaragara. Ariko iyambere irakunzwe ugereranije. 

Nka ikigezweho mu kiyobora binyuze mukurwanya hasi, byongera uburyo bwa voltage igabanya ingano ya kabili isabwa, itanga ubushyuhe buke, kandi ikongerera icyarimwe icyarimwe, icyerekezo-gitwara igice cyambukiranya igice cyiyongera kiganisha hanze nini nini uburemere bwa kabili ya diameter, mugihe hamwe nigihe cyo kwishyuza ubushyuhe burebure bizagenda byiyongera buhoro buhoro, byihishe, ubu buryo bwa bateri ni ibyago byinshi.

Kwishyuza 800V: “Kwishyuza ikirundo ibibazo bimwe bitaziguye”

800V yishyuza byihuse nayo ifite ibisabwa bitandukanye kuruhande rwikirundo:

Niba urebye urwego rwumubiri, uko voltage yiyongera, igishushanyo mbonera cy’ibikoresho bifitanye isano ntigishobora kwiyongera, nko kuri IEC60664 urwego rw’umwanda urwego 2 ibikoresho byo mu bwoko bwa insulasiyo 1 intera ndende y’ibikoresho bisabwa kuva kuri 2mm kugeza kuri 4mm, ubwishingizi bumwe Ibisabwa byo guhangana biziyongera, hafi ya creepage intera hamwe nibisabwa byokwirinda birasabwa kwiyongera kubintu bibiri, bisaba imbaraga nyinshi mumashusho yabanjirije.

Ibi bisaba gushushanya sisitemu yabanjirije voltage kugirango yongere igaragaze ubunini bwibikoresho bijyanye, harimo umuhuza, umurongo wumuringa, ingingo, nibindi, usibye kwiyongera kwa voltage nabyo bizaganisha kubisabwa cyane kugirango kuzimya arc, gukenera ibikoresho bimwe na bimwe. nka fus, guhinduranya agasanduku, guhuza, nibindi, kugirango utezimbere ibisabwa, ibi bisabwa biranakoreshwa mugushushanya imodoka.

Sisitemu yo kwishyiriraho ingufu za 800V, nkuko byavuzwe haruguru, ikeneye kongera sisitemu yo gukonjesha ikora hanze, gukonjesha ikirere gakondo gukonje ndetse no gukonjesha ntibishobora kuba byujuje ibyangombwa bisabwa kugirango umurongo wimbunda wishyirire hejuru yimodoka irangire yumuriro. imiyoborere nayo irasabwa cyane kuruta ikindi gihe cyose, kandi iki gice cyubushyuhe bwa sisitemu uburyo bwo kugabanya no kugenzura kuva kurwego rwibikoresho nurwego rwa sisitemu nigihe gikurikira cyo kunoza no gukemura ikibazo cyibitekerezo;

hiyongereyeho, iki gice cyubushyuhe ntabwo ari ubushyuhe buturuka gusa, ahubwo nubushyuhe buturuka kumuriro mwinshi, ntabwo aricyo gice cyonyine cya sisitemu, ahubwo nubushyuhe buturuka kumuriro mwinshi. Ntabwo ubushyuhe buzanwa no kwishyurwa birenze urugero, ahubwo nubushyuhe buzanwa nibikoresho byamashanyarazi yumurongo mwinshi, kuburyo rero bwo gukora igenzura ryigihe kandi gihamye, gihamye, kandi gifite umutekano kugirango gikureho ubushyuhe nibyingenzi cyane, bidafite gusa ibintu byagezweho ariko nanone gutahura sisitemu, nko kwishyuza ubushyuhe burigihe-no kugenzura neza.

Kugeza ubu ku isoko DC yishyuza ikirundo cy’ibisohoka ni 400V, kandi ntishobora guhita igera kuri 800V yumuriro wa batiri, bityo rero ikeneye kongera ingufu za DCDC izongera ingufu za 400V kugeza kuri 800V, hanyuma ikishyuza bateri, bisaba imbaraga nyinshi zo guhinduranya inshuro nyinshi, ikoreshwa rya silicon karbide kugirango isimbuze module gakondo ya IGBT niyo nzira nyamukuru yo guhitamo inzira, nubwo moderi ya silicon carbide module ishobora kongera ingufu ziva mubirundo byumuriro, ariko kandi no kongera imbaraga zumusaruro wikirundo. Nubwo moderi ya silicon karbide irashobora kongera imbaraga zumusaruro wikirundo no kugabanya igihombo, igiciro nacyo kizamuka cyane, kandi ibisabwa na EMC biri hejuru.

Vuga muri make. Ubwiyongere bwa voltage buzaba murwego rwa sisitemu kandi urwego rwibikoresho rugomba kunozwa, urwego rwa sisitemu harimo sisitemu yo gucunga amashyuza, sisitemu yo gukingira umuriro, nibindi, hamwe nurwego rwibikoresho birimo ibikoresho bya rukuruzi hamwe nibikoresho byamashanyarazi kugirango bitezimbere.
