Kubanini, abaqhubi, kunye neenjineli ezilawula iinkqubo zebhetri ye-lithium, umbuzo ophindaphindiweyo uvela rhoqo: "Ngaba iphakheji entsha yebhetri ifuna imodyuli eyongezelelweyo yokulinganisela?" Ngelixa iiseli ezihambelana nomatshini zihlala zithembekile ekuqaleni komjikelo wazo wobomi, impilo yexesha elide kunye nokusebenza rhoqo kwayo nayiphi na iphakheji eqhagamshelwe kuluhlu kuxhomekeke kakhulu ekugcineni ukuhambelana okuchanekileyo kombane.I-Active Balancerisebenza njengotyalo-mali olusebenza kakuhle kakhulu nolungabizi kakhulu ukukhusela olu lungelelwano kulo lonke ixesha lokusebenza kwezixhobo. Ngokusebenzisa ulwazi lobuchwephesha bokwenyani kunye nedatha yobunjineli evelaIHeltec Energy (iChengdu Heltec Energy Technology Co., Ltd.)Eli nqaku liphonononga isizathu sokuba iteknoloji yokulinganisela esebenzayo ikhawuleza ibe yinxalenye ebalulekileyo yokuphucula ukusebenza kwebhetri, ukhuseleko lwenkqubo, kunye nobude bexesha kwizicelo zamandla zanamhlanje.
Q1: Kutheni iiLithium Battery Packs zifumana iVoltage Imbalance?
Yonke ipakethi yebhetri ye-lithium, nokuba injani na umgangatho wayo wokuqala, ixhomekeke kwisiphumo "sebharele yebhetri." Esi simanga senzeka kuba akukho ziseli zimbini ezifanayo ngokugqibeleleyo. Utshintsho oluncinci, oluvela kwimilo yangaphakathi yeekhemikhali, ukunyamezelana kokwenziwa, amazinga athile okuzikhupha, kunye novakalelo lokuguquguquka kobushushu bangaphandle ziqhelekile kuzo zombini iiseli ze-lithium-ion kunye ne-lithium iron phosphate (LiFePO₄).
Njengoko ipakethi yebhetri idlula kwimijikelo yokutshaja nokukhupha amanzi ngokuphindaphindiweyo, la mahluko mancinci aqokelelana aze asasazeke. Xa iseli enomthamo ophezulu kancinci okanye ukumelana kwangaphakathi okuphantsi ifikelela kumda wayo ophezulu wevolthi ngokukhawuleza kunezakwamakhelwane bayo, inokubangela ukunqunyulwa kokutshaja kwangaphambi kwexesha okanye ukuvalwa kokukhusela. Ngokwahlukileyo koko, ngexesha lokukhupha amanzi, iseli ebuthathaka kakhulu inokubetha umda wevolthi ephantsi kuqala. Ekuhambeni kwexesha, oku kungalingani kuyakhula. Iseli ebuthathaka kakhulu—"i-stave emfutshane" kwi-barrel—ilawula kwaye inciphise amandla asebenzisekayo epakethi yonke, inyanzela inkqubo ukuba iyeke ukusebenza nangona iiseli ezisele zisaphethe amandla amaninzi agciniweyo.
Umbuzo 2: Ngaba i-Passive Balancing Yanele? Kutheni kufuneka ndicebise i-Active Balancer?
Ukunciphisa ezi ngxaki zixhaphakileyo, iinkqubo ezininzi zemveli zixhomekeke ekulinganiseni okungasebenziyo. Le ndlela isebenzisa izithinteli ukukhupha amandla agqithisileyo eeseli ezine-voltage ephezulu njengobushushu de i-voltage yazo ifane neqela lonke. Nangona ukulinganisela okungasebenziyo kubiza kancinci, kunomda ngokwemvelo: kusebenza kuphela ngokususa amandla, nto leyo engenzi nto ukuphucula umthamo wenkqubo iyonke, kwaye ivelisa ubushushu obungeyomfuneko, obunokuba yingozi kwimpilo yebhetri kwiindawo ezinobushushu obuphezulu.
Ngokwahlukileyo koko, i-Active Balancer—njengeemodyuli eziphambili ezenziwe yiHeltec Energy—isebenzisa iindlela zokudlulisa amandla ezintsonkothileyo endaweni yokusasaza. Zisebenzisa ii-super-capacitors ezisebenzayo eziphezulu okanye impendulo yokulungisa i-transformer push-pull, ezi zixhobo zihambisa amandla ngokukhutheleyo ukusuka kwiiseli ezine-voltage ephezulu ukuya kwezo zine-voltage ephantsi. Le ndlela isebenza kakuhle kakhulu kuba igcina amandla axabisekileyo endaweni yokuwachitha. Iiyunithi eziphambili, kuquka ezo zenziwe yiChengdu Heltec Energy Technology Co., Ltd., zibonelela ngeempawu ezininzi: azifuni mahluko athile e-voltage ukuze ziqale ukusebenza, zisebenza ngokulinganayo kuyo yonke ipakethi, kwaye zinokubonelela nge-constant balancing currents eqinileyo ukusuka kwi-0 ukuya kwi-10A kuxhomekeke kumahluko oxinzelelweyo. Olu buchule bobuchwephesha luvumela ukulungiswa kwe-voltage echanekileyo, yexesha langempela, rhoqo kufikelela ukuchaneka ngaphakathi kwe-0.01V.
Umbuzo 3: Ukufaka i-Active Balancer Module kuyiphucula njani i-Overall Pack Performance?
Ukudibanisa imodyuli yokulinganisela esebenzayo kuguqula iphakheji yebhetri ukusuka kwingqokelela yeeseli zomntu ngamnye, ezinokuthi zahlukane zibe yinkqubo yamandla edibeneyo, ehlala ixesha elide. Inzuzo ephambili ye-Heltec Energy 5A active balancer ikubuchule bayo bokukhawulezisa ukuphelisa iingxaki ezibangelwa kukubola kweseli nganye. Ngokuqinisekisa ukuba iseli nganye ekwimo ye-8S ukuya kwi-32S ihlala kuluhlu lwevolthi eqinileyo, elungisiweyo, imodyuli ivumela inkqubo yolawulo lwebhetri ukuba isebenzise amandla apheleleyo afumanekayo ephakheji ngokufanelekileyo.
Le nkqubo yokugcinwa rhoqo yandisa ubomi benkonzo esebenzayo yephakheji ngokuthintela uxinzelelo olunzulu lomjikelo kwiiseli ezibuthathaka. Ngaphezu koko, ezi modyuli zenzelwe ukuqina kwiindawo ezifuna amandla kwimizi-mveliso nakwindawo ezihambayo. Iiyunithi ezininzi zinezixhobo zokukhusela ezifana nokhuseleko olukrelekrele lobushushu obugqithisileyo, iindlela zokulala ezine-voltage ephantsi ukuthintela ukukhupha umoya kakhulu ngexesha lokungasebenzi, kunye neengubo ezikhethekileyo ezi-3 ezibonelela ngokhuseleko olubalulekileyo ekuthinteleni ukufuma, uthuli, kunye nezinto ezirhabaxa. Ngokugcina amanqanaba e-voltage ahambelanayo, uxinzelelo kwiiseli nganye luyancitshiswa, nto leyo ekhokelela ekusebenzeni kwenkqubo ekhuselekileyo, ezinzileyo, nethembekileyo ngakumbi kuzo zonke izicelo ezahlukeneyo, kubandakanya izithuthi zombane, iinkqubo zokugcina amandla ezimileyo, kunye nezixhobo zamandla kwimizi-mveliso.
Umbuzo 4: Ngaphantsi Kwaziphi Iimeko apho Ukufakelwa Kuyimfuneko Okanye KunokuLibaziseka?
Ukugqiba ukuba kufuneka ufake i-active balancer kudla ngokuxhomekeka kwisicelo esithile, uxinzelelo lokusingqongileyo, kunye neprofayili yokusetyenziswa kwenkqubo yebhetri. Kwiinkqubo ezinengxaki yoxinzelelo olukhulu lokusebenza, ezifana neepakethi zokugcina amandla ezine-4S okanye uthotho oluphezulu, iipakethi zebhetri ezindala apho iiseli zisenokuba ziphuhlise iiprofayili ezahlukeneyo zokuwohloka, okanye iisetingi ezihlala zisebenza ngokwahlukana kwevolthi eqhubekayo edlula i-30mV, ukufakelwa kuyacetyiswa kakhulu. Ezi meko zixhamla ngoko nangoko kukuzinziswa kunye nokukhuselwa okubonelelwa yimodyuli yokulinganisela. Ngokwahlukileyo koko, ukuba inkqubo isebenzisa ipakethi yeseli entsha, ehambelana ngokugqibeleleyo kwaye isebenza phantsi kwemijikelo emifutshane kakhulu, enganzulu yokukhupha itshaja, ukufakelwa kwangoko kusenokungabi yinto ebalulekileyo, nangona ukujonga kwangaphambili kuhlala kucetyiswa kakhulu njengoko ipakethi ikhula.
