–Niba ushaka kwishyurwa byihuse kumodoka yawe yamashanyarazi, ntushobora kugenda nabi na voltage nini, tekinoroji igezweho yo kwishyiriraho ibirundo

Ikoranabuhanga ryinshi kandi rinini cyane

Mugihe intera igenda yiyongera buhoro buhoro, hari ibibazo nko kugabanya igihe cyo kwishyuza no kugabanya ikiguzi cya nyirubwite, kandi umurimo wambere nukuzamura ingano ya module kugirango ugere kumashanyarazi. Kuva imbaraga zaikirundoahanini biterwa nimbaraga zo hejuru ya module yo kwishyuza, kandi igarukira kubunini bwibicuruzwa, umwanya wo hasi hamwe nigiciro cyo gukora, gusa kongera umubare wa module ntibikiri igisubizo cyiza. Kubwibyo, uburyo bwo kongera imbaraga za module imwe utongeyeho amajwi yinyongera byabaye ikibazo cya tekiniki kokwishyuza abakora moduledukeneye gutsinda byihutirwa.

Ibikoresho byo kwishyuza DCigera ku bushobozi buhebuje bwo kwishyuza binyuze mu buhanga bugezweho na tekinoroji ya voltage. Hamwe no kwiyongera gahoro gahoro ya voltage nimbaraga, ibi birashyira imbere ibisabwa bikomeye kugirango imikorere ihamye, gukwirakwiza ubushyuhe neza no guhindura imikorere ya module yo kwishyuza, nta gushidikanya ko ishyiraho ibibazo bya tekinike yo kwishyuza abakora module.

Imbere yisoko ryamasoko yingufu zihuta zishyurwa, abakora module yinguzanyo bakeneye guhora bashya kandi bakazamura ikoranabuhanga ryibanze kandi bakubaka inzitizi zabo bwite. Ibi bizaba urufunguzo rwamarushanwa azaza kumasoko, gusa nukumenya ikoranabuhanga ryibanze, kugirango udatsindwa mumarushanwa akaze yisoko.

1) Inzira-igezweho: urwego rwo kuzamurwa ni ruto, kandi ibisabwa mu micungire yubushyuhe ni byinshi. Dukurikije amategeko ya Joule (formula Q = I2Rt), kwiyongera k'umuyaga bizongera cyane ubushyuhe mu gihe cyo kwishyuza, ibyo bikaba bisabwa cyane kugira ngo ubushyuhe bugabanuke, nk'igisubizo cya Tesla cyihuta cyane cyo kwishyuza, ikirundo cya V3 kirenze urugero gifite amashanyarazi arenga 600A, gisaba ibikoresho byinshi byo kwishyiriraho ingufu, kandi mu gihe kimwe, bikagira ingufu nyinshi zo kwishyiriraho ingufu. 5% -27% SOC, kandi kwishyuza neza ntabwo byuzuye. Kugeza ubu, abakora amamodoka yo mu gihugu ntabwo bahinduye ibintu byihariye muri gahunda yo gukwirakwiza ubushyuhe, kandihejuru-yo kwishyuza ibirundowishingikirize cyane kuri sisitemu yo kwiyubaka, bivamo ibiciro byo kuzamurwa hejuru.

2) Inzira yumuvuduko mwinshi: Nuburyo busanzwe bukoreshwa nabakora imodoka, bushobora kuzirikana ibyiza byo kugabanya gukoresha ingufu, kuzamura ubuzima bwa bateri, kugabanya ibiro, no kubika umwanya. Kugeza ubu, bigarukira ku bushobozi bwo guhangana n’amashanyarazi y’ibikoresho bya IGBT bishingiye kuri silikoni, igisubizo cyihuta cyo kwishyurwa gikunze gukoreshwa n’amasosiyete y’imodoka ni urubuga rwa 400V rwihuta cyane, ni ukuvuga ko ingufu za 100kW zishobora kugerwaho hamwe n’amashanyarazi ya 250A (ingufu za 100kW zishobora kwishyurwa 10min kuri 100km). Kuva aho Porsche itangiriye 800V yumuriro mwinshi cyane (kugera ku mbaraga za 300KW no kugabanya ibyuma bifata amashanyarazi menshi), amasosiyete akomeye yimodoka yatangiye gukora ubushakashatsi no gushyiraho 800V yumuriro mwinshi. Ugereranije na 400V ya platifomu, 800V yumurongo wa voltage ifite amashanyarazi ntoya ikora, ikiza ingano yicyuma cyogukoresha insinga, igabanya igihombo cyimbere cyumuzunguruko, kandi ikazamura ingufu nubushobozi bwingufu ziyoberanya.

Kugeza ubu, amashanyarazi ahoraho yama voltage yumurongo wa 40kW module yinganda ni 300Vdc ~ 1000Vdc, ibyo bikaba bihujwe no gukenera kwishyurwa ryimodoka zitwara abagenzi 400V zigezweho, bisi 750V hamwe nigihe kizaza 800V-1000V yimodoka nini cyane; Ibisohoka biva mumashanyarazi ya 40kW module ya Infineon, Telai na Shenghong irashobora kugera kuri 50Vdc ~ 1000Vdc, ukurikije ibikenerwa byo kwishyurwa byimodoka zifite ingufu nke. Kubireba imikorere rusange yimikorere ya module, 40kW yubushobozi buhanitse bwaBeiHai Imbaragakoresha ibikoresho byamashanyarazi bya SIC, kandi impinga irashobora kugera kuri 97%, ikaba iri hejuru yikigereranyo cyinganda.
