Ni iki gikoresho gikwirakwiza ingufu z'amashanyarazi menshi ku modoka?
Igice cyo gukwirakwiza ingufu nyinshi z'imodoka (PDU) ni igice cy'ingenzi muri sisitemu y'amashanyarazi menshi y'imodoka nshya, ahanini ishinzwe gukwirakwiza no gucunga ingufu kugira ngo ibice byazo bifite ingufu nyinshi bikore neza kandi mu buryo butekanye.
Imirimo y'ingenzi
Youdaoplaceholder0 Gukwirakwiza no gucunga ingufu: Gukwirakwiza neza umuriro w'amashanyarazi ufite ingufu nyinshi ku bikoresho bitandukanye by'amashanyarazi, nka moteri zitwara, sisitemu zo gusharija, nibindi.
Youdaoplaceholder0 charge no kugenzura imirasire y'amazi : Icunga inzira yo gushyushya no gusohora imirasire y'amazi ya sisitemu ifite amashanyarazi menshi, harimo kurinda umutwaro mwinshi, kurinda imirasire migufi n'uburyo bwo gupima amashanyarazi menshi.
Kugenzura ingufu nke za Youdaoplaceholder0: kugenzura ingufu no kugenzura uko ibintu bifite ingufu nyinshi bihagaze binyuze mu miyoboro ifite ingufu nke.
Igishushanyo mbonera cyo gukwirakwiza ubushyuhe cya Youdaoplaceholder0: Hari PDU zikoresha imiterere yo gukonjesha amazi cyangwa gukonjesha umwuka kugira ngo zemeze ko ibikoresho bifite ingufu nyinshi bikenera gukwirakwiza ubushyuhe.
Ibiranga imiterere
PDU ishobora guhuza imikorere nka modules za DC-DC conversion, modules za OBC charger, na BMS main control, bigatuma habaho igishushanyo mbonera gihuriweho cyane. Urugero, modules eshatu muri imwe na modules enye muri imwe zishobora guhuza imikorere myinshi kugira ngo zihuze n'ibyo ubwoko butandukanye bw'imodoka bukeneye.
Igikoresho gikwirakwiza ingufu nyinshi mu modoka (PDU) ni cyo gikoresho cy’ingenzi cyo kugenzura sisitemu ifite ingufu nyinshi mu binyabiziga bishya, ahanini kigakora ku nshingano zo gukwirakwiza ingufu no kurinda umutekano. Inshingano zacyo z’ingenzi ni izi zikurikira:
Ikwirakwizwa ry'ingufu z'amashanyarazi zifite ingufu nyinshi
PDU ikwirakwiza umuyoboro w’amashanyarazi ufite ingufu nyinshi (300-800V) uva kuri batiri y’amashanyarazi ku bice by’ingenzi nka moteri itwara, charger iri mu bwato (OBC), converter ya DC/DC, na compressor y’amashanyarazi ikoresha amashanyarazi. Urugero, umuyoboro w’amashanyarazi ugenzura moteri utwara amashanyarazi ugera kuri 60% by’umusaruro w’amashanyarazi, naho andi asigaye agashyirwa muri sisitemu zifasha nko gusharija no gushyushya.
Uburyo bwo kurinda umutekano
Harimo uburinzi bw'umuyoboro ukabije w'amashanyarazi, umuyoboro mugufi w'amashanyarazi, umuyoboro ukabije w'amashanyarazi n'ubushyuhe bukabije:
Uburinzi bw'umuyoboro wa Youdaoplaceholder0: Iyo umuyoboro urenze 120% by'agaciro kagenwe mu masegonda 2, contactor nyamukuru irafungwa maze fisi ikavuzwa
Uburinzi bwa Youdaoplaceholder0 Short-circuit : Iyo impedance iri munsi ya 100mΩ, circuit irafungwa mu masegonda make
Uburinzi bw'ubushyuhe burenze urugero bwa Youdaoplaceholder0: Iyo ubushyuhe bwa busbar y'umuringa burenze 110℃, bugabanya buhoro buhoro umutwaro cyangwa bukagabanya ingufu
Kumenya uburyo bwo gukingira imiterere y'icyuma cya Youdaoplaceholder0: bishobora kumenya ibyago byo kunanirwa gukingira imiterere y'icyuma <500Ω/V no gutera inzogera
Guhuza no kugenzura sisitemu
Ihuza module yo guhindura DC/DC, ishami rigenzura gusharija n'imikorere y'ingenzi ya BMS, kandi ishyigikira imiterere ya module. Amabwiriza ya VCU yakirwa binyuze muri CAN bus kugira ngo igenzure uburyo bwo gusohora/gutanga umuriro w'amashanyarazi ku muyoboro wa voltage nyinshi (igihe cyo gusubiza <50ms), kandi ingamba zo gukwirakwiza ingufu zihinduka (nk'uko gushyira imbere kuzimya imizigo itari ngombwa mu gihe cyo gushyushya).
Ibipimo by'imikorere
Uburyo bwo gukwirakwiza umusaruro ≥98% (umutwaro uri munsi y’umubare w’ibipimo)
Imbaraga zo gukingira umuriro zishobora kwihanganira 2500V AC mu gihe cy'amasegonda 60 nta gucika intege
Igihe cy'imikorere ya mashini yohereza umuriro mwinshi (high-voltage relay) kirenga 100.000 cycles
Ishyigikira imikorere yo guhuza umutwaro n'ibindi (igabanya ikoreshwa ry'ingufu ku kigero cya 5-8%)
Amakosa mu gice gikwirakwiza umuriro w'amashanyarazi menshi mu modoka akunze gutera amashanyarazi adasanzwe, guhagarara kwa charger cyangwa kwangirika kw'ibice by'amashanyarazi, ibyo bikaba bigaragara cyane nka:
Ikibazo cy'ikosa
Kunanirwa kwa sisitemu y'amashanyarazi ya Youdaoplaceholder0: Ikinyabiziga ntigishobora kwihuta nk'uko bisanzwe, kandi umuvuduko ntarengwa ni muto (urugero, umuvuduko uri muri iyo dosiye ni 40km/h gusa)
Youdaoplaceholder0 Gushaja bidasanzwe : Gushaja AC/DC birahagarara cyangwa ntibishobora gutangira (reba amakosa ari ku murongo wa contactor cyangwa sensor)
Youdaoplaceholder0 Itangazo ry'igikoresho : Igaragaza "Ikosa rya sisitemu y'amashanyarazi menshi" cyangwa "Ikosa rya sisitemu y'amashanyarazi"
Youdaoplaceholder0 Uburinzi bw'ibice by'amashanyarazi : Sisitemu ihita igabanya umuyoboro w'amashanyarazi menshi kugira ngo hirindwe kwangirika gukomeye (nk'ibikoresho bigenzura moteri, bateri z'amashanyarazi, nibindi)
Impamvu zisanzwe
Youdaoplaceholder0 circuit interlock circuit ifite voltage nyinshi : ibimenyetso bidasanzwe byo kugenzura bituma sisitemu ifunga (nk'aho umurongo udashobora gukora neza, gucika intege kw'umurongo)
Ikosa ry'imbere mu gasanduku k'itumanaho: contactor y'agasanduku k'itumanaho gafite voltage nyinshi irahagarara, kandi kumenya aho amazi aturuka birananirana
Youdaoplaceholder0 Umuyoboro mugufi cyangwa umurego mwinshi: kwangirika k'urwego rwo gukingira insinga rw'umuyoboro w'amashanyarazi menshi bituma umuyoboro mugufi ugera hasi
Uburyo bwo gusuzuma indwara
Youdaoplaceholder0 Soma kode y'ikosa : Shaka kode y'ikosa yihariye (nka P1E0300, B042900) ukoresheje dekoderi
Ikizamini cy'ishusho ya Youdaoplaceholder0: Kureba niba ikimenyetso cy'izunguruka ry'umuyoboro w'amashanyarazi menshi ari ibisanzwe (hakenewe ibikoresho by'umwuga)
Igenzura ry'ikizamini cya Youdaoplaceholder0 : Reba uko ibice by'amashanyarazi (nk'uko icyuma gitanga ingufu gihagaze) mu bihe by'ikosa ryakozwe mu buryo bwa "simulated fault"
Ni byiza kuvugana n'ikigo cy'inzobere mu kubungabunga ibidukikije kugira ngo gipime amashanyarazi menshi kugira ngo hirindwe ingaruka zishobora guterwa no kwiyambura.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
