ibhethri le-LiFePO4 elingu-72V: Isixazululo Sokugcina Amandla Esisebenza Ngokuphezulu Sezinhlelo Zokusebenza Ezithuthukile

ibhethri le-lifepo4 elingu-72v

Ibhethri le-LiFePO4 elingu-72V liyisisombululo sokugcina amandla esihamba phambili esihlanganisa amandla aphezulu kagesi nezici zokuphepha ezivelele. Lolu hlelo lwebhethri oluthuthukile lusebenzisa i-lithium iron phosphate chemistry ukuze lunikeze amandla ahambisanayo ngenkathi kugcinwa ukuzinza okuphawulekayo ezimweni ezihlukahlukene zokusebenza. Njengoba inamandla ombane angu-72V, la mabhethri aklanyelwe ngokukhethekile ukuhlinzeka ukusebenza okuthembekile kwezinhlelo zokusebenza ezinzima ezifana nezimoto zikagesi, izinhlelo zokugcina amandla elanga, nemishini yezimboni. Ukwakhiwa kwebhethri kuqukethe amaseli amaningi axhumene ngokulandelana nangokwakheka okuhambisanayo, avikelwe uhlelo oluphelele lokuphathwa kwebhethri (i-BMS) eliqapha futhi lithuthukise ukusebenza. Lawa mabhethri ngokuvamile anikela ngamandla asukela ku-40Ah kuya ku-200Ah, okwenza afaneleke ngezidingo zamandla ahlukahlukene. Ukwakheka kwe-LiFePO4 kuqinisekisa isikhathi sokuphila esifinyelela kuma-3000-5000 cycles, okuhlala isikhathi eside kunezindlela ezijwayelekile zokwenza i-lead-acid. Ngaphezu kwalokho, la mabhethri agcina amandla aphuma eqinile kuwo wonke umjikelezo wawo wokukhishwa, okuqinisekisa ukusebenza okuqhubekayo kuze kube yilapho esephelile. Uhlelo oluhlanganisiwe lokuphatha ukushisa luvimbela ukufudumala ngokweqile ngesikhathi sokushaja nokukhishwa, kanti ukwakheka kwe-cell okunamandla kumelana nokukhishwa kokushisa, okwenza kube enye yezinketho eziphephe kakhulu zebhethri le-lithium etholakalayo.

Uhlelo lwebhethri lwe-72V LiFePO4 lunikeza izinzuzo eziningi ezicindezelayo ezenza kube ukukhetha okuhle kakhulu kwezicelo ezihlukahlukene. Okokuqala nokubaluleke kakhulu, ukuminyana kwayo kwamandla okuphakeme kuvumela ukugcinwa kwamandla amaningi ngendlela eqinile, okuvumela ukusetshenziswa kahle kwendawo ezimotweni nasezinhlelweni zokugcina. Ukuphila komjikelezo we-battery okuphawulekayo kwamacala angu-3000-5000 kunciphisa kakhulu izindleko eziphelele zokuphatha, njengoba kudingeka ukushintshwa okuncane ngokuhamba kwesikhathi. Ukuphepha kungenye inzuzo enkulu, njengoba ikhemikhali ye-LiFePO4 izinzile futhi imelana nokushabalala kokushisa, kuqede ingozi yomlilo noma yokuqhuma okuvamile kwezinye ubuchwepheshe be-lithium. Ikhono lokushaja ngokushesha kwebhethri livumela izikhathi zokushaja ngokushesha, ngokuvamile kufinyelela kumthamo ongu-80% kungakapheli ihora elilodwa kusetshenziswa imishini efanele yokushaja. Kucatshangelwa nezindaba zemvelo, njengoba la mabhethri engenazo izinsimbi ezinzima ezinobuthi futhi engavuselelwa ngokuphelele. Ukuwa kwamandla aphansi ngesikhathi sokukhishwa kuqinisekisa ukunikezwa kwamandla okuqhubekayo, okwenza kube kuhle kakhulu ekusetshenzisweni okudinga amandla okuphuma azinzile. Ukubekezelelana nokushisa kungenye inzuzo ebalulekile, njengoba la mabhethri enza ngokuthembekile ezimweni ezibandayo nezishisayo, ngokuvamile kusuka ku -20 ° C kuya ku-60 ° C. I-BMS ehlanganisiwe inikeza ukuvikelwa okuphelele ngokumelene nokushaja ngokweqile, ukukhishwa ngokweqile, kanye ne-short Ngaphezu kwalokho, la mabhethri awadingi ukulungiswa, okususa isidingo sokulungiswa njalo noma ukuhlolwa kwama-electrolyte okuvamile kumabhethri e-lead-acid. Ukusebenza kahle kwamandla aphezulu, ngokuvamile okungaphezu kuka-98%, kunciphisa ukulahleka kwamandla ngesikhathi sokushaja nokukhishwa, okuholela ezindlekweni zokusebenza eziphansi.

Ukuphila Isikhathi Eside Ngokungavamile Nokwethenjelwa

Uhlelo lwebhethri i-LiFePO4 engu-72V luvelele ngokuphila kwalo isikhathi eside, lunikeza isikhathi sokuphila esihlaba umxhwele esidlula iningi lamazobuchwepheshe bebhethri abakhona namuhla. Uma zisetshenziswa futhi zigcinwa kahle, lezi bhethri zihlale zinikeza imijikelezo ephelele yokushaja nokukhishwa engu-3000 kuya ku-5000 ngenkathi zigcina ngaphezu kuka-80% womthamo wazo wokuqala. Lokhu kuqina okuyingqayizivele kusho ukuthi isebenza iminyaka engaba ngu-8 kuya kwengu-10 ngendlela ethembekile uma isetshenziswa njalo, okwenza kube utshalomali olusebenzayo lwezindleko zokusetshenziswa kwesikhathi eside. Ukwakheka kwamakhemikhali kwebhethri kuhlala kuzinzile phakathi nempilo yayo, kuvimbela izinkinga zokuwohloka ezivamile kwamanye amabhethri asuselwa ku-lithium. Lokhu kuzinza kuqinisekisa ukusebenza okuqhubekayo nokulethwa kwamandla okuthembekile kuyo yonke impilo yesevisi yebhethri, kunciphisa imvamisa yokushintshwa nezindleko ezihambisana nakho. Ukwakhiwa okuqinile nezinto ezisezingeni eliphezulu ezisetshenziselwa ukukhiqiza la mabhethri kunomthelela ekuqineni kwawo okuvelele, okwenza afaneleke ekusetshenzisweni okuqinile lapho ukwethembeka kubalulekile khona.

Izicatshulwa eziphumaphi nokuhlola

Ukuphepha kubaluleke kakhulu ekwakhiweni kwesistimu yebhethri ye-LiFePO4 engu-72V, efaka izingqimba eziningi zokuvikela ukuqinisekisa ukusebenza okuphephile ngaphansi kwazo zonke izimo. Ibhethri liqukethe i-Advanced Battery Management System (BMS) eqhubeka ibheka amapharamitha abalulekile kuhlanganise i-voltage, i-current, kanye nokushisa kuwo wonke amaseli. Lolu hlelo olucubungulayo lunikeza ukuvikelwa ngesikhathi sangempela ezinkingeni ezivamile zebhethri njengokushaja ngokweqile, ukukhishwa ngokweqile, ukuvinjelwa okufushane nokushaja okushisayo. Ukwakheka kwe-LiFePO4 ngokwako kuphephe kakhulu kunamanye amasu asekelwe ku-lithium, kugcina ukuzinza ngisho nangaphansi kwezimo ezimbi. Ukwakhiwa kwebhethri kuhlanganisa izinto ezikhuthazela ilangabi nokuhlukaniswa kwamangqamuzana okuqinile, okwandisa ukuphepha. Kunemishini eminingi yokuvikela engadingekile ehlanganiswe ezingeni leselula nelesethi, okuqinisekisa ukuthi noma yiziphi izinkinga ezingase zibe khona zixazululwa ngokushesha ngaphambi kokuba zibe izinkinga ezinkulu. Lendlela ebanzi yokuphepha yenza la mabhethri afaneleke ngokukhethekile ekusetshenzisweni lapho ukuthembeka nokuphepha kubalulekile.

Ukuhambisana kwezicelo ezihlukahlukene

Uhlelo lwebhethri i-LiFePO4 engu-72V lubonisa ukuhlukahluka okuphawulekayo ezinhlotsheni eziningi zezicelo, okwenza kube yisixazululo sokuphehla amandla esifanele izimo eziningi. I-voltage yayo ephezulu kanye nemininingwane yamandla ayenza ilungele kakhulu izimoto zikagesi, kuhlanganise izithuthuthu, izinqola zegalufu nezimoto zezimboni, lapho ukulethwa kwamandla okuqhubekayo kubalulekile. Ukuqina kwamandla aphezulu kakhulu kwebhethri nokuklanywa kwayo okuhlangene kwenza kube lula ukuhlanganisa izinto ezihlukahlukene ngaphandle kokudela isikhala. Ukuhambisana kwayo kufinyelela nasezinhlelweni zokugcina amandla avuselelekayo, lapho ihlaba umxhwele khona ekulondolozeni amandla elanga nomoya ukuze isetshenziswe kamuva. Amandla aphuma ngamandla asebenza kahle futhi amandla aphezulu okulawula amandla enza ibhethri lilungele ukusetshenziswa ezimbonini ezifuna amandla, kuhlanganise namathuluzi kagesi nemishini. Ukuzivumelanisa kwesistimu nemithombo ehlukene yokushaja kanye nekhono layo lokusebenza ngokufana kuhlinzeka ngokuguquguquka ekwakhiweni nasekusetshenzisweni kwesistimu. Lokhu kusebenza kahle kukhuliswa ububanzi bokushisa kokusebenza kwebhethri nekhono layo lokugcina ukusebenza ngaphansi kwezimo ezihlukile zemvelo.
