Kubanikazi, opharetha, kanye nonjiniyela abaphatha izinhlelo zebhethri le-lithium, umbuzo ophindaphindayo uvame ukuvela: "Ingabe iphakethe elisha lebhethri lidinga ngempela imodyuli yokulinganisela eyengeziwe?" Ngenkathi amaseli afaniswe efektri ngokuvamile ethembekile ekuqaleni komjikelezo wawo wokuphila, impilo yesikhathi eside kanye nokusebenza okuqhubekayo kwanoma yiliphi iphakethe elixhunywe ochungechungeni kuncike kakhulu ekugcineni ukuhambisana okuqondile kwe-voltage.I-Active Balancerisebenza njengotshalomali olusebenza kahle kakhulu nolungabizi kakhulu ukuvikela lokhu kuhambisana kuyo yonke impilo yokusebenza kwemishini. Ngokusebenzisa ukuqonda kwezobuchwepheshe bangempela kanye nedatha yobunjiniyela evelaI-Heltec Energy (i-Chengdu Heltec Energy Technology Co., Ltd.)Lesi sihloko sihlola ukuthi kungani ubuchwepheshe bokulinganisela obusebenzayo busheshe bube yingxenye ebalulekile yokwenza ngcono ukusebenza kwebhethri, ukuphepha kohlelo, kanye nokuphila isikhathi eside kuzo zonke izinhlelo zokusebenza zamandla zesimanje.
Q1: Kungani Amaphakethe Ebhethri E-Lithium Ehlangabezana Nokungalingani Kwe-Voltage?
Iphakethe ngalinye lebhethri le-lithium, kungakhathaliseki ukuthi linjani ekuqaleni, libhekene nomphumela "wombhobho webhethri" ongenakugwenywa. Lesi simo senzeka ngoba awekho amaseli amabili afana ngokuphelele. Ukwehluka okuncane, okungokwemvelo kokwakheka kwamakhemikhali angaphakathi, ukubekezelelana kokukhiqiza, amazinga athile okuzikhipha, kanye nokuzwela ekushintsheni kokushisa kwangaphandle kujwayelekile kumaseli e-lithium-ion kanye ne-lithium iron phosphate (LiFePO₄).
Njengoba iphakethe lebhethri lidlula emijikelezweni yokushaja nokukhipha okuphindaphindiwe, lo mehluko omncane kakhulu uyaqoqana futhi usakazeke. Lapho iseli elinamandla aphezulu kancane noma ukumelana kwangaphakathi okuphansi lifinyelela umkhawulo walo we-voltage ephezulu ngokushesha kunomakhelwane balo, lingabangela ukunqanyulwa kokushaja ngaphambi kwesikhathi noma ukuvala okuvikelayo. Ngokuphambene nalokho, ngesikhathi sokukhipha, iseli elibuthakathaka kakhulu lingafika kuqala kumkhawulo we-voltage ephansi. Ngokuhamba kwesikhathi, lokhu kungalingani kuyakhula. Iseli elibuthakathaka kakhulu—"i-stave emfushane kakhulu" emgqonyeni—lilawula futhi linciphise amandla asebenzisekayo ephaketheni lonke, liphoqa uhlelo ukuthi luyeke ukusebenza ngisho nalapho amaseli asele esaphethe inani elikhulu lamandla agciniwe.
Umbuzo 2: Ingabe Ukulinganisela Okungashintshi Kwanele? Kungani Kufanele Sincome I-Active Balancer?
Ukuze kuncishiswe lezi zinkinga ezivamile, izinhlelo eziningi zendabuko zithembele ekulinganiseni okungasebenzi. Le ndlela ngokuvamile isebenzisa ama-resistor ukusabalalisa amandla amaningi amaseli ane-voltage ephezulu njengokushisa kuze kube yilapho i-voltage yawo ifana neqembu lonke. Nakuba ukulinganisela okungasebenzi kahle kungabizi kakhulu, kunqunyelwe ngokwemvelo: kusebenza kuphela ngokukhipha amandla, okungenzi lutho ukuthuthukisa umthamo wesistimu iyonke, futhi kukhiqiza ukushisa okungadingekile, okungaba yingozi empilweni yebhethri ezindaweni ezinokushisa okuphezulu.
Ngokuphambene nalokho, i-Active Balancer—njengezimojula ezithuthukisiwe eziklanywe yi-Heltec Energy—isebenzisa amasu okudlulisa amandla ayinkimbinkimbi kunokusabalalisa. Ngokusebenzisa ama-super-capacitor asebenza kahle kakhulu noma impendulo yokulungisa i-transformer push-pull, lawa madivayisi ahambisa amandla ngenkuthalo kusuka kumaseli ane-voltage ephezulu kuya kulawo ane-voltage ephansi. Le ndlela isebenza kahle kakhulu ngoba igcina amandla abalulekile kunokuwachitha. Amayunithi athuthukile, kufaka phakathi lawo akhiqizwe yi-Chengdu Heltec Energy Technology Co., Ltd., anikeza izici eziningi: awadingi umehluko othile we-voltage ukuze aqale ukusebenza, asebenze ngokuvumelanayo kulo lonke iphakethe, futhi angaletha ama-current balancing currents aqinile asukela ku-0 kuya ku-10A kuye ngokuthi umehluko wengcindezi otholiwe ungakanani. Leli khono lobuchwepheshe livumela ukulungiswa kwe-voltage okunembile, kwesikhathi sangempela, ngokuvamile kufinyelela ukunemba ngaphakathi kwe-0.01V.
Q3: Ukufaka i-Active Balancer Module Kuyithuthukisa Kanjani Ukusebenza Kwephakethe Eliphelele?
Ukuhlanganisa imojuli yokulinganisela esebenzayo kuguqula ngempumelelo iphakethe lebhethri kusuka eqoqweni lamaseli ngamanye, angaba ahlukene abe uhlelo lwamandla oluhlangene noluhlala isikhathi eside. Inzuzo eyinhloko ye-Heltec Energy 5A active balancer isekukwazini kwayo kokususa izithiyo ezibangelwa ukubola kweseli ngalinye. Ngokuqinisekisa ukuthi iseli ngalinye elingaphakathi kokucushwa kwe-8S kuya ku-32S lihlala ngaphakathi kwebanga lamandla aqinile, alungiselelwe kahle, imojuli ivumela uhlelo lokuphatha ibhethri ukuthi lusebenzise amandla aphelele atholakalayo ephaketheni ngempumelelo enkulu.
Le nqubo yokulungisa eqhubekayo yandisa kakhulu impilo yesevisi yokusebenza kwephakethe ngokuvimbela ukucindezeleka okujulile komjikelezo kumaseli abuthakathaka. Ngaphezu kwalokho, lawa mamojula aklanyelwe ukuqina ezindaweni ezidingayo zezimboni nezindawo ezihambayo. Amayunithi amaningi afaka izinto zokuvikela ezifana nokuvikelwa okuhlakaniphile kokushisa ngokweqile, izindlela zokulala eziphansi ukuze kuvinjelwe ukukhishwa ngokweqile ngesikhathi sokungasebenzi, kanye nezingubo ezikhethekile ezintathu ezinikeza ukuvikelwa okubalulekile ekumelaneni nomswakama, uthuli, nezinto ezigqwalisayo. Ngokugcina amazinga e-voltage ahambisanayo, ukucindezeleka kumaseli ngamanye kuyancishiswa, okuholela ekusebenzeni kwesistimu okuphephile, okuzinzile, nokuthembekile kuzo zonke izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi izimoto zikagesi, izinhlelo zokugcina amandla ezimile, kanye nezinsiza zikagesi zezimboni.
Q4: Kungaphansi Kwaziphi Izimo Ukufakwa Okudingekayo Noma Okuhlehliswayo?
Ukunquma ukuthi kufanele ufake i-balancer esebenzayo kuvame ukuncika kuhlelo lokusebenza oluthile, ukucindezeleka kwemvelo, kanye nephrofayili yokusetshenziswa kwesistimu yebhethri. Kumasistimu avame ukuba nokucindezeleka okukhulu kokusebenza, njengamaphakethe okugcina amandla anezilungiselelo zochungechunge lwe-4S noma ngaphezulu, amaphakethe amabhethri amadala lapho amaseli kungenzeka ukuthi athuthukise amaphrofayili okuwohloka ahlukile, noma amasethingi avame ukusebenza ngomehluko we-voltage oqhubekayo odlula i-30mV, ukufakwa kunconywa kakhulu. Lezi zimo zizuza ngokushesha ekuzinzeni nasekuvikelweni okunikezwa yi-module yokulinganisela. Ngokuphambene nalokho, uma uhlelo lusebenzisa iphakethe leseli elisha sha, elifanelana kahle futhi lisebenza ngaphansi kwemijikelezo emifushane kakhulu, engajulile yokukhipha ukushaja, ukufakwa okusheshayo kungase kungabi yinto ebaluleke kakhulu, yize ukuqapha okuqhubekayo kusalokhu kunconywa kakhulu njengoba iphakethe liguga.
Isiphetho
Ukuzinza kwephakethe lebhethri le-lithium kubalulekile ekusebenzeni kwalo kwesikhathi eside kanye nokusebenza kahle kwezezimali. Ngokubhekana nezimbangela eziyinhloko zokungalingani kwamaseli ngokudluliselwa kwamandla okuthuthukisiwe, ubuchwepheshe obunikezwa yi-Heltec Energy kusiza abasebenzisi ukuthi bandise ukutshalwa kwezimali kwabo, bathuthukise ukuphepha kokusebenza, futhi bandise impilo yokusebenza kwemishini yabo. Kungakhathaliseki ukuthi bagcina izimoto zezentengiselwano zobungcweti noma uhlelo lokugcina amandla oluzimele, ukuphathwa kwamandla okusebenza ngendlela ecacile kuyindlela ecacile nephumelelayo yokufeza impilo yebhethri engcono.
Kulabo abafuna ukuqonda izidingo ezithile zokulinganisela zokusethwa kwebhethri okuhlukile noma abanentshisekelo ekucacisweni okuningiliziwe kobuchwepheshe bokucushwa kwamaseli ahlukahlukene, izinsiza eziphelele kanye nolwazi lomkhiqizo lungatholakala ku-https://www.heltec-energy.com/
