Ukuchonga Ukusilela Kwebhetri Ngaphaya Kwemida YeVolthi Engaguqukiyo
Iingcali zokulungisa ezijongene nokulungiswa kwamandla eeseli ezininzi zihlala zihlangabezana nemeko engaqhelekanga yokuxilonga: ipakethi edibeneyo ibonisa i-voltage iyonke ebonakala iqhelekile kwiiterminal zayo eziphambili ngexesha lokulinda, kodwa ixesha layo lokusebenza lihla ngokukhawuleza phantsi komthwalo. Xa imoto okanye iyunithi yokugcina amandla ibuya nokuncipha okukhulu komgama, ukuhlolwa okubonakalayo akuvezi zimpawu zomzimba, kwaye ukufundwa kwe-voltage iyonke kuyasilela ukwahlula indawo yangaphakathi yokusilela. Ungazibona njani iiseli ezimbi kwipakethi yebhetri? Ukuthembela kumlinganiselo we-macroscopic ukuvavanya iinethiwekhi ezintsonkothileyo ze-multi-series akwanelanga, njengoko kufuneka uvavanyo lwasekhaya, olunokulinganiswa lomthamo weseli nganye kunye nokumelana kwangaphakathi ukuze kufunyanwe iziphene ezifihlakeleyo zesakhiwo.
Ukungakwazi kweendlela zemveli zokufumanisa iseli eyonakeleyo kuvela kwiindlela zokuziphatha zesekethe yombane ezisisiseko. Kwisimo sochungechunge, ukulinganisa i-voltage ye-static open-circuit kudla ngokugquma ukudakumba okukhulu kwe-voltage okwenzeka phantsi kwemithwalo enamandla. I-multimeter yedijithali eqhelekileyo ayinakuphinda iphindaphinde uxinzelelo lokusebenza lwehlabathi lokwenyani okanye ilinganise ukulahleka kombane okwenyani. Umzekelo, iseli eyonakeleyo kakhulu—enomthamo wokwenyani ongaphantsi kwama-60%—isenokutshaja ukuya kumlinganiselo oqhelekileyo we-voltage xa ingasebenzi, kodwa idilike ngokukhawuleza ngexesha lokukhupha kwaye ibangele ukunqunyulwa kokhuseleko kwinqanaba lenkqubo kwangoko. Ngenxa yokuba iseli ehlulekayo yokwenyani izibonakalisa ngokulahleka komthamo omkhulu okanye ukumelana kwangaphakathi okuguquguqukayo okungaqhelekanga (AC IR), ukufumanisa ezi anomalies ezisisiseko kufuna izixhobo zovavanyo ezizinikeleyo. Ukusombulula le ngxaki yokuxilonga,I-Chengdu Heltec Energy Technology Co., Ltd. (i-Heltec Energy)ibonelela ngezixhobo zokuxilonga ezichanekileyo neziyilelwe ukwenza uhlalutyo lomthamo weseli enye kunye nokumelana, esebenza njengesisombululo esiqinisekisiweyo seshishini sokwahlula iiseli ezingaphantsi komgangatho.
Iindlela zokuLungisa ngokuchanekileyo ngeHeltec Energy Hardware
Ukwahlula izinto zangaphakathi ezineziphene kwiindibano ezintsonkothileyo kufuna indlela edibeneyo yokuvavanya. IHeltec Energy ijongana nezi mfuno zobugcisa ngokusebenzisauluhlu lwezixhobo ezikhethekileyoyenzelwe ukuvavanya iimpawu zombane ngamnye.
1. Ukulinganiswa koMbane oQinisekisiweyo
Indlela ephambili yokuqinisekisa iseli eyonakeleyo ibandakanya ukujikeleza kwe-galvanostatic okupheleleyo, okucwangcisiweyo. Besebenzisa abavavanyi bomthamo webhetri ye-HT-BCT ecwangcisiweyo okanye abavavanyi bomthwalo womthamo we-HT-CC abakhethekileyo, iingcali zenza iiprofayili zokutshaja, ukukhupha, ukuphumla, kunye nokujikeleza ngokuzenzekelayo. Ezi nkqubo zigcina idatha eqhubekayo, zivumela abasebenzisi ukuba babale ukuhanjiswa kwe-ampere-hour (Ah) okanye i-watt-hour (Wh) echanekileyo yeeseli nganye. Nasiphi na iseli enye okanye umtya wochungechunge ongaphumeleliyo ukuvelisa ubuncinci i-60% yomthamo wayo oqhelekileyo owenziweyo ngexesha lomjikelo wokukhupha oqhelekileyo uchazwa njengomviwa osengozini ofuna ukususwa okanye ukwehla komgangatho.
2. Uqinisekiso oluPhambili lokuchasana kwangaphakathi
Idatha yomthamo iqinisekiswa ngakumbi ngovavanyo oludibeneyo lokumelana kwangaphakathi lwe-AC. Ngenxa yokuba uvavanyo lomthamo lufuna ixesha elide lokusebenza, iprofayili yokumelana kwangaphakathi isebenza njengendlela yokuxilonga yesibini ngokukhawuleza. Ii-Heltec Energy capacity analyzers zibonisa amandla okulinganisa i-AC IR akwibhodi. Ukuba ukumelana kwangaphakathi kweseli ethile kuphambuka ngaphezu kwe-20% kumyinge osisiseko wephakheji, okanye ukuba iseli ehlukanisiweyo ibonisa ukunyuka okukhawulezileyo kokumelana phantsi kwemithwalo esebenzayo, iseli itshixiwe njengendawo yokusilela eqinisekisiweyo.
3. Uvavanyo oluhambelanayo olungangenisi ntsholongwane kwiipakethi ezinkulu
Kwiibhetri ezinkulu zezithuthi zoshishino okanye zombane, ukuqhaqhazwa kovavanyo lweseli nganye kudala umsebenzi omninzi. Abavavanyi beHeltec Energy abahlukeneyo abaneetshaneli ezininzi bayoyisa le ngxaki ngokuvumela uvavanyo oluphezulu ngaphandle kokuqhawula izihlanganisi zepakethi eziphambili. Ukusebenza ngeeparameter zetshaneli ezizimeleyo—ezifana noluhlu lwetshaneli enye ukusuka kwi-0.3V ukuya kwi-5V kunye nemisinga ehlengahlengiswayo ukuya kuthi ga kwi-50A (inokukhuliswa ukuya kwi-200A ngoqwalaselo oluhambelanayo)—ihardware idwelisa iiseli ezininzi ngaxeshanye. Uyilo ludibanisa iindlela zokukhusela ezibanzi, kubandakanya i-overvoltage, uqhagamshelo olubuyela umva, ukuqhawula, kunye nolawulo lobushushu olukrelekrele, ukuqinisekisa ukusebenza okukhuselekileyo ngexesha leenkqubo zokuxilonga ezinombane ophezulu.
4. Uvavanyo oluHlanganisiweyo kunye nokulinganisela okusebenzayo
Ukuze kuphuculwe ukusebenza kakuhle komsebenzi, izixhobo ezizodwa zokuxilonga zidibanisa ukufunyanwa kwedatha kunye nokusasazwa kwakhona kwamandla ngexesha langempela. Izixhobo zohlalutyo lwe-HT-CJ kunye nokulinganisa zenza ukulinganisela okusebenzayo ngokudluliselwa kwamandla ngelixa ngaxeshanye zenza uvavanyo lomthamo. Endaweni yokuchitha amandla njengobushushu ngokusebenzisa ii-resistor ezingasebenziyo, ezi yunithi zidlulisela itshaja ukusuka kwiiseli ze-voltage ephezulu ukuya kwiiseli ze-voltage ephantsi. Esi senzo siphindwe kabini sivumela iingcali ukuba zichonge ukonakala okungapheliyo ngokomzimba ngelixa zisombulula ukungalingani kweeseli okuguquguqukayo kwinqanaba elinye lokusebenza, zinciphisa ixesha loqhagamshelo lwezixhobo ngokubanzi.
Isakhelo seSigqibo esiCwangcisiweyo emva koKuxilonga
Nje ukuba i-hardware iqokelele amanqaku edatha achanekileyo, imisebenzi yokulungisa inokutshintsha ukusuka ekusombululeni iingxaki ngokubanzi ukuya kwi-matrix yokwahlulahlula ecwangcisiweyo, eqhutywa yidatha. Kwimeko apho uvavanyo lomthamo luqinisekisa ukuba zonke iiseli zihlala zingaphezulu kakhulu komlinganiselo we-60% kwaye iprofayili ye-AC IR ibonisa ukufana okuqinileyo, iphakheji ithathwa njengesempilweni ngokwasemzimbeni. Iingcali zingafaka i-Heltec Energy active balancer esisigxina ukunciphisa ukushukuma kwexesha elizayo, yandisa ubomi bendibano iyonke.
Kungenjalo, xa ukuxilongwa kwahlula iseli enye okanye umtya wochungechunge olukwindawo ethile ngokuncipha okukhulu komthamo okanye ukumelana okuphezulu, inkqubo yokulungisa iyalela ukuba kutshintshwe kuphela loo seli ithile. Emva kokutshintshwa ngokwasemzimbeni, iphakheji idlula kumjikelo opheleleyo wokulinganisela ukuze ihambelane neseli entsha nomtya okhoyo. Kwimeko apho imitya yochungechunge oluninzi ibonisa ukuwohloka okubanzi kunye nokwahluka okukhulu kokumelana, ukulungiswa kwendawo ethile akwenzeki, kwaye ukuhlanganiswa kusetyenziselwa ukusetyenziswa kobomi besibini—njengokugcina amandla okuhlala—okanye kukhutshwe ngokupheleleyo ukuze kusetyenziswe kwakhona izinto.
Isiphelo
Ukwahlula iiseli ezineziphene ngaphakathi koqwalaselo lweeseli ezininzi kufuna ukudlula uvavanyo lwe-voltage olusisiseko ukuya kwiimitha ezichanekileyo nezilinganisiweyo.
