Bumwe mu buryo bw'ingenzi bw'imodoka nshya zifite ingufu ni bateri z'amashanyarazi.Ubwiza bwa bateri bugena ikiguzi cyimodoka zamashanyarazi kuruhande rumwe, nurwego rwo gutwara ibinyabiziga byamashanyarazi kurundi ruhande.Ikintu cyingenzi cyo kwemerwa no kwakirwa vuba.
Ukurikije imiterere ikoreshwa, ibisabwa hamwe nimirima ikoreshwa ya bateri yingufu, ubushakashatsi nubwoko bwiterambere rya bateri zamashanyarazi mugihugu ndetse no mumahanga ni hafi: bateri ya aside-aside, bateri ya nikel-kadmium, bateri ya nikel-hydride, bateri ya lithium-ion, selile ya lisansi, nibindi, muribyo iterambere rya bateri ya lithium-ion yitabirwa cyane.
Imyitwarire ya batiri yubushyuhe
Inkomoko yubushyuhe, igipimo cyo kubyara ubushyuhe, ubushobozi bwa bateri nubundi bipimo bifitanye isano na module ya batiri yingufu bifitanye isano ya hafi na miterere ya bateri.Ubushyuhe bwarekuwe na bateri bushingiye kumiterere yimiti, ubukanishi n amashanyarazi nibiranga bateri, cyane cyane imiterere ya reaction ya electrochemic.Ingufu zubushyuhe zitangwa muri reaction ya bateri zirashobora kugaragazwa nubushyuhe bwa batiri Qr;amashanyarazi ya polarike itera imbaraga za voltage ya bateri gutandukana nimbaraga zayo zingana na electromotive, kandi gutakaza ingufu biterwa na polarisiyasi ya batiri bigaragazwa na Qp.Usibye reaction ya bateri igenda ikurikiza ikigereranyo cya reaction, hari na reaction zimwe.Mubisanzwe reaction zirimo kwangirika kwa electrolyte hamwe na batiri yonyine.Ubushyuhe bwo kuruhande butangwa muriki gikorwa ni Q.Mubyongeyeho, kubera ko bateri iyo ariyo yose byanze bikunze izarwanya, ubushyuhe bwa Joule Qj izabyara mugihe ikigezweho.Kubwibyo, ubushyuhe bwuzuye bwa bateri nigiteranyo cyubushyuhe bwibintu bikurikira: Qt = Qr + Qp + Qs + Qj.
Ukurikije uburyo bwihariye bwo kwishyuza (gusohora), ibintu nyamukuru bitera bateri kubyara ubushyuhe nabyo biratandukanye.Kurugero, iyo bateri isanzwe yishyurwa, Qr nikintu cyiganje;kandi mugice cyanyuma cyo kwishyuza bateri, kubera kubora kwa electrolyte, reaction zimpande zitangira kugaragara (ubushyuhe bwuruhande ni Qs), mugihe bateri yuzuye hafi yuzuye kandi ikarenza urugero, Ikibaho cyane nukwangirika kwa electrolyte, aho Qs yiganje .Ubushyuhe bwa Joule Qj biterwa nubu hamwe no guhangana.Uburyo bukoreshwa muburyo bwo kwishyuza bukorwa mugihe gihoraho, kandi Qj nigiciro cyihariye muriki gihe.Ariko, mugihe cyo gutangira no kwihuta, ikigezweho ni kinini.Kuri HEV, ibi bihwanye numuyoboro wa amperes icumi kugeza kuri amper.Muri iki gihe, ubushyuhe bwa Joule Qj nini cyane kandi ihinduka isoko nyamukuru yo gusohora ubushyuhe bwa batiri.
Duhereye ku micungire yubushyuhe bwo kugenzura, sisitemu yo gucunga amashyuza (HVH) irashobora kugabanywamo ubwoko bubiri: bukora kandi butemewe.Urebye uburyo bwo guhererekanya ubushyuhe buringaniye, sisitemu yo gucunga ubushyuhe irashobora kugabanywamo: gukonjesha ikirere (Ubushyuhe bwo mu kirere), amazi akonje (Ubushyuhe bwa PTC), hamwe nicyiciro-gihindura ububiko bwubushyuhe.
Kugirango habeho ubushyuhe hamwe na coolant (PTC Coolant Heater) nkibikoresho, birakenewe gushiraho itumanaho ryogukwirakwiza ubushyuhe hagati ya module nigikoresho cyamazi, nkikoti ryamazi, kugirango hakorwe ubushyuhe butaziguye no gukonjesha muburyo bwa convection nubushyuhe kuyobora.Uburyo bwo guhererekanya ubushyuhe bushobora kuba amazi, Ethylene glycol cyangwa na firigo.Hariho kandi no guhererekanya ubushyuhe butaziguye mu kwibiza igice cya pole mumazi ya dielectric, ariko hagomba gufatwa ingamba zo gukumira kugirango hatabaho inzira ngufi.
Gukonjesha gukonjesha muri rusange bifashisha guhanahana ubushyuhe bwikirere hanyuma bikinjiza coco muri bateri kugirango habeho guhanahana ubushyuhe bwa kabiri, mugihe gukonjesha gukomeye bifashisha moteri ya coolant-fluid hagati yubushyuhe bwo hagati, cyangwa PTC gushyushya amashanyarazi / gushyushya amavuta yumuriro kugirango ugere kubukonje bwibanze.Gushyushya, gukonjesha kwambere hamwe na cabine yabagenzi umwuka / ubukonje bwa firigo-amazi.
Kuri sisitemu yo gucunga amashyanyarazi akoresha umwuka n’amazi nkibikoresho, imiterere nini kandi nini cyane kubera gukenera abafana, pompe zamazi, guhinduranya ubushyuhe, ubushyuhe, imiyoboro nibindi bikoresho, kandi ikoresha ingufu za batiri kandi igabanya ingufu za batiri .ubucucike n'ubucucike.
Sisitemu yo gukonjesha amazi ikonjesha ikoresha ubukonje (50% amazi / 50% ya Ethylene glycol) kugirango yimure ubushyuhe bwa batiri muri sisitemu ya firigo ikonjesha ikirere ikoresheje icyuma gikonjesha, hanyuma ikangiza ibidukikije ikoresheje kondenseri.Ubushyuhe bwamazi ya bateri ikonjeshwa na bateri Biroroshye kugera ku bushyuhe buke nyuma yo guhana ubushyuhe, kandi bateri irashobora guhindurwa kugirango ikore ku bushyuhe bwiza bwakazi;ihame rya sisitemu ryerekanwa mu gishushanyo.Ibice byingenzi bigize sisitemu ya firigo harimo: kondenseri, compressor yamashanyarazi, impumatori, kwaguka kwaguka hamwe na valve yazimye, gukonjesha bateri (kwaguka kwaguka hamwe na valve ifunga) hamwe nu miyoboro ihumeka, nibindi.;gukonjesha amazi akubiyemo harimo: pompe yamazi yamashanyarazi, bateri (harimo amasahani yo gukonjesha), gukonjesha bateri, imiyoboro yamazi, ibigega byo kwagura nibindi bikoresho.
