Isesengura ryubushyuhe bwo gucunga ubushyuhe bwa Batteri yubushyuhe bwoherejwe hagati

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.

Urebye uburyo bwo gucunga neza ubushyuhe, sisitemu yo gucunga ubushyuhe irashobora kugabanywamo ubwoko bubiri: bukora kandi bworoshye.Urebye uburyo bwo guhererekanya ubushyuhe buringaniye, sisitemu yo gucunga ubushyuhe irashobora kugabanywamo: gukonjesha ikirere, gukonjesha amazi, hamwe nububiko bwamashanyarazi.

Gucunga ubushyuhe hamwe numwuka nkuburyo bwo kohereza ubushyuhe

Uburyo bwo guhererekanya ubushyuhe bugira ingaruka zikomeye kumikorere nigiciro cya sisitemu yo gucunga amashyuza.Gukoresha umwuka nkuburyo bwo guhererekanya ubushyuhe ni ukumenyekanisha mu buryo butaziguye umwuka kugirango unyure muri module ya bateri kugirango ugere ku ntego yo gukwirakwiza ubushyuhe.Mubisanzwe, abafana, guhumeka no gusohoka nibindi bisabwa.
Ukurikije amasoko atandukanye yo gufata ikirere, muri rusange hari uburyo bukurikira:
1 Gukonjesha gusa hamwe no guhumeka hanze
2. Gukonjesha / gushyushya pasiporo kubagenzi bahumeka umwuka
3. Gukonjesha / gushyushya umwuka wo hanze cyangwa abagenzi
Imiterere ya sisitemu yimikorere iroroshye kandi ikoresha neza ibidukikije bihari.Kurugero, niba bateri ikeneye gushyuha mugihe cyitumba, ibidukikije bishyushye mubice byabagenzi birashobora gukoreshwa muguhumeka umwuka.Niba ubushyuhe bwa bateri buri hejuru cyane mugihe utwaye kandi ingaruka zo gukonjesha umwuka mubyumba byabagenzi ntabwo ari nziza, umwuka ukonje uturutse hanze urashobora guhumeka kugirango ukonje.

Kuri sisitemu ikora, hagomba gushyirwaho sisitemu yihariye kugirango itange imirimo yo gushyushya cyangwa gukonjesha kandi igenzurwe yigenga ukurikije uko bateri imeze, nayo yongerera ingufu ingufu nigiciro cyikinyabiziga.Guhitamo sisitemu zitandukanye ahanini biterwa nibisabwa na bateri.

Imicungire yubushyuhe hamwe namazi nkuburyo bwo kohereza ubushyuhe

Kugirango ubushyuhe bwoherezwa hamwe namazi nkibikoresho, birakenewe gushiraho itumanaho ryogukwirakwiza ubushyuhe hagati ya module nuburyo bwamazi, nka jacket yamazi, kugirango habeho gushyushya no gukonjesha mu buryo butaziguye muburyo bwa convection no gutwara ubushyuhe.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 amazi ya pasiporo muri rusange akoresha uburyo bwo guhanahana ubushyuhe bwikirere hanyuma akinjiza coco muri bateri kugirango habeho guhanahana ubushyuhe bwa kabiri, mugihe gukonjesha gukomeye bifashisha moteri ya coolant-fluide yo hagati yubushyuhe, cyangwa gushyushya amashanyarazi / gushyushya amavuta yubushyuhe kugirango ugere kubukonje bwibanze.Gushyushya, gukonjesha kwambere hamwe na cabine yabagenzi umwuka / ubukonje bwa firigo-amazi.
Sisitemu yo gucunga amashyanyarazi hamwe numwuka namazi nkuko bisanzwe bisaba abafana, pompe zamazi, guhinduranya ubushyuhe, ubushyuhe (Ubushyuhe bwo mu kirere).
(PTC ikonjeshaumushyushyaSisitemu yo gukonjesha ya bateri ikonjesha amazi ikoresha coolant (50% amazi / 50% ya Ethylene glycol) kugirango yimure ubushyuhe muri bateri muri sisitemu ya firigo ikonjesha ikirere ikoresheje icyuma gikonjesha, hanyuma ikangiza ibidukikije ikoresheje kondenseri.Ubushyuhe bw’amazi yatumijwe mu mahanga biroroshye kugera ku bushyuhe bwo hasi nyuma yo guhana ubushyuhe na firime ya bateri, kandi bateri irashobora guhinduka kugirango ikore ku bushyuhe bwiza bwakazi;ihame rya sisitemu ryerekanwa mu gishushanyo.Ibice byingenzi bigize sisitemu ya firigo harimo: kondenseri, compressor yamashanyarazi, impumateri, kwaguka kwaguka hamwe na valve ihagarara, gukonjesha bateri (kwaguka kwaguka hamwe na valve ihagarara) hamwe nu miyoboro ihumeka, nibindi.;gukonjesha amazi akonje arimo:pompe y'amazi y'amashanyarazi, bateri (harimo isahani yo gukonjesha), gukonjesha bateri, imiyoboro y'amazi, ibigega byo kwagura n'ibindi bikoresho.
