Ukuvavanya impilo yebhetri kunye neeMetriki zokuxilonga
Xa umgama wesikuta sombane uhla ukusuka kwiikhilomitha ezingama-50 ukuya kwezingama-30 ngelixa ibhetri ihleli injalo, iingcali zijongene nengxaki: ingaba ikhemistri yonakele, okanye umahluko wevolthi ephezulu uvala amandla asebenzisekayo? Abaqhubi abaninzi balahla iimodyuli ngaphambi kwexesha ngenxa yokungabikho koqinisekiso olucwangcisiweyo lokwahlula phakathi kokungalingani okuguqukayo kunye nokulahleka okungenakuguqulwa.
Ukujongana nale nto,IChengdu Heltec Energy Technology Co., Ltd., iseka inkqubo yokuqinisekisa ecwangcisiweyo. Ngokusebenzisa indlela echanekileyo nechanekileyoumvavanyi womthamo webhetri, iingcali zivelisa idatha eqinisekisiweyo ukuze zigqibe ngokuchanekileyo ukuba zigcine, zilungise, okanye zitshintshe iphakheji.
Njengoko ukuxhomekeka kwiinkqubo zamandla esibini kusanda kumashishini e-logistics, ukulawula impilo yebhetri kuye kwatshintsha kwaba yinto ephambili yokusebenza. Ukusilela okungacwangciswanga kunye nokuxilongwa okungasebenzi kakuhle kudala iindleko ezingafunekiyo kwaye kudlalisa izinto ezixabisekileyo. Ukutshintshela kuvavanyo oluqhelekileyo kuvumela izixhobo ukuba zikhusele utyalo-mali lwezixhobo ngelixa zihlangabezana neenjongo zokusebenza kakuhle. Iindlela zokusebenza zokuxilonga zanamhlanje zisusa ukuqikelela ngokwahlula ukonakala kwesakhiwo ekushukumeni kwamandla ombane amancinci, ukuqinisekisa ukuba yonke into esetyenziswayo ixhaswa ziimilinganiselo zokusebenza ezinokulinganiswa.
Inyathelo 1: Uhlolo Lokuqala Lokubona NokuHlola I-Voltage Evulekileyo
Iiprotokholi zokuxilonga ziqala ngovavanyo olusisiseko lomzimba nombane ukuze kubonwe iimpazamo ezibonakalayo zoomatshini okanye eziyingozi. Iingcali kufuneka zihlole isingxobo sebhetri ukuze zibone ukudumba, ukuvuza kwe-electrolyte, okanye ukubola kwesiphelo, njengoko ezi mpawu zibonisa iingozi zokhuseleko ezikhawulezileyo ezingayi kudlula uvavanyo olongezelelweyo. Emva kokususwa kwebhetri, ipakethe yebhetri kufuneka ihlale ikwimeko yokungenzi nto, ingami phambi kokulinganisa i-voltage ye-open-circuit edibeneyo.
Ukuba i-voltage ehlanganisiweyo yehla kakhulu ngaphantsi komlinganiselo oqhelekileyo wokusika, umonakalo onzulu wokukhupha umbane unokubakho. Kwinqanaba le-modular, umahluko we-voltage yesekethe evulekileyo edlula i-100 millivolts phakathi kweentambo zeseli nganye usebenza njengesilumkiso sokuqala sokwahlukana okukhulu kweeseli. Nangona oku kungalingani kubonisa umda wokusebenza, uvavanyo lwesibini lobungakanani luhlala luyimfuneko ukumisela ukuba isakhiwo seseli esingaphantsi sonakaliswe ngokusisigxina.
Inyathelo lesi-2: Uvavanyo loBuchule bokuHlalutya ukuHlalutya ukubola
Ukuze kuchongwe ngokuchanekileyo imeko yokusebenza kwepakethi, iingcali kufuneka zilinganise ukugcinwa kwamandla okwenyani ngovavanyo olulawulwayo. Ngokulandela imigangatho yokusebenza yeHeltec Energy, ipakethi yebhetri idlula kwimijikelo epheleleyo, ezenzekelayo yokutshaja kunye nokukhupha ehambelana nemigaqo eqhelekileyo yeeseli. Umvavanyi womthamo webhetri ozinikeleyo unyanzelisa ummiselo ochanekileyo wangoku wokurekhoda imilinganiselo echanekileyo ye-ampere-hour, evumela amaqela ezobugcisa ukuba ahlele impilo yepakethi ibe ngamanqanaba amathathu asebenzayo ngokusekelwe ekusebenzeni okulinganisiweyo:
● Umthamo $\ge$ 80% woHlelo oluQhelekileyo:Ibhetri iyasebenza kakhulu kwisicelo sayo sokuqala. Ukunciphisa ukwahluka kwexesha elizayo kunye nokucothisa ukuguga kwendawo, kucetyiswa ukuba ufake imodyuli esebenzayo yokulinganisela ukugcina ukufana kweeseli okuqhubekayo.
● Umthamo ophakathi kwe-60% kunye ne-80% kunye ne-Persistent Voltage Imbalance:Le pakethi ibonisa imida yokusebenza, kodwa ukonakala kwayo kunokubangelwa kukungalingani kweeseli endaweni yokudinwa kweekhemikhali ngokwenene. Iingcali kufuneka ziqhagamshele le pakethi kwi-HT-CJ32S25A ibhetri ye-lithium equalizer kunye ne-analyzer ekhethekileyo ukuze kuqaliswe ukusebenza kwe-voltage ekujoliswe kuyo kunye nemijikelo yokulinganisela iiseli ngaphambi kokuba kwenziwe uqinisekiso lomthamo wesibini.
● Umthamo < 60% ukuya kwi-70% yoHlelo oluQhelekileyo:Iiseli zifikelele kwimida yazo yenkonzo efanelekileyo kwizicelo ezifunwa kakhulu. Kulo mda, iphakheji iphawulwa ukuba irhoxiswe kwinkqubo yayo ephambili kwaye ihlolwe ukuba ifuna uhlengahlengiso lwesibini, olungenamsebenzi kakhulu lokugcina izinto ezisisigxina okanye ukutshintshwa ngokupheleleyo.
Ngethuba lolu vavanyo, oomatshini bokuxilonga balandela kwaye badwebe iigrafu zexesha langempela zokutshaja kunye nee-discharge curves. Ukufunyanwa kwedatha echanekileyo kuthintela ukufundwa komthamo okhohlisayo okubangelwa zii-overcharges zesikhashana okanye ukunqunyulwa kombane ngaphambi kwexesha.
Inyathelo lesi-3: Umlinganiselo wokutshintshana wokuchasana kwangaphakathi kwangoku
Nangona iimetrikhi zomthamo ziqinisekisa ukugcinwa kwamandla apheleleyo, ukonakala kwesakhiwo ngaphakathi kwephakheji kuchongwa ngovavanyo lokumelana kwangaphakathi. Iinkqubo zokugcina amandla ngokuzenzekelayo ezivela kwiHeltec Energy zidibanisa imisebenzi yokuvavanya ukumelana kwangaphakathi etshintshanayo ukuze kuvavanywe iimeko zeseli nganye.
Umahluko wokuxhathisa kwangaphakathi odlula i-20% phakathi kweentambo zeseli nganye, okanye ukunyuka okukhawulezileyo kwiseli enye, kukhomba ngokuthe ngqo ekuqhekekeni kwangaphakathi, njengokugqwala kwegridi okanye ukuwohloka kokwahlukanisa. Nokuba ipakethi ibonisa amandla amkelekileyo xa iphantsi kwemithwalo elula, ukumelana kwangaphakathi okuphezulu kubangela uxinzelelo olukhulu lobushushu kunye nokuhla kwevolthi phantsi kweemfuno zamandla aphezulu. Ukuchonga ezi seli zokuxhathisa okuphezulu kuvumela abaqhubi ukuba bahlukanise kwaye batshintshe iintambo ezithile ezonakaliswe endaweni yokulahla yonke imodyuli ngaphambi kwexesha.
Inyathelo lesi-4: Izigqibo zokugqibela zoLondolozo kunye noTshintsho
I-matrix yokuxilonga ecwangcisiweyo yenza lula inkqubo yokugqibela yokwenza izigqibo ibe ziindlela zokusebenza ezicacileyo, eziqhutywa yidatha ngaphandle kokuxhomekeka kwiitshekhi zokukhangela eziqinileyo. Xa idatha yovavanyo eqokelelweyo ityhila amandla aneleyo apheleleyo kunye nokumelana kwangaphakathi okufanayo kuzo zonke iintambo zeseli, iphakheji yebhetri iyasuswa ukuze iqhubeke nokufakwa kwinkqubo yayo ephambili, kwaye iingcali zihlala zicebisa ukufaka izixhobo zokulinganisela ezisebenzayo njengendlela yokuthintela ukugcinwa. Kwiipakethi ezibonisa amandla angaphantsi kunye nokwahlukana kwamandla aphezulu, inkqubo idluliselwa kwimigaqo yokulinganisela ejolise kuyo kunye nokuvuselelwa kweeseli kusetyenziswa i-equalizer ezinikeleyo ukususa izithuba ze-voltage yangaphakathi kunye nokubuyisela ukuhambelana kwentambo yokuqala.
Ngokwahlukileyo koko, ukuba uvavanyo lobungakanani luveza ukulahleka okukhulu kwamandla apheleleyo okanye ukusasazeka okubanzi kokumelana kwangaphakathi phakathi kweentambo nganye nganye, indlela eyahlukileyo iyimfuneko ukukhusela ukuthembeka kwezixhobo. Phantsi kwezi meko, iintambo zeeseli ezichaphazelekayo okanye yonke ipakethi yeeseli ezininzi kufuneka zithunyelwe ngokusisigxina ukuze zitshintshwe okanye zinikezelwe kwimisebenzi yokugcina yesibini engadingi mfuneko ukuze kuthintelwe ukubaleka kobushushu kwindawo ethile. Olu hlalutyo lucwangcisiweyo luqinisekisa ukuba i-hardware elungileyo ayilahlwa ngaphambi kwexesha, ngelixa izinto ezichaphazelekileyo zahlulwe ngokwenkqubo ngaphambi kokuba zibangele ukusilela kwenkqubo.
Isiphelo
Ukuthembela kwiimitha ezinokulinganiswa ezivela kumvavanyi wobuchule bebhetri kunye ne-equalizer ephucukileyo kuvumela amaziko eenkonzo ukuba asuse ukuqikelela ekugcinweni kwebhetri. I-Chengdu Heltec Energy Technology Co., Ltd. ixhasa usetyenziso lwemizi-mveliso yehlabathi ngobunjineli bezixhobo zolawulo lwamandla ezibanzi eziphucula ukhuseleko lwebhetri kunye nobude bayo. Ukuze ufumane isikhokelo esikhethekileyo ekukhetheni izixhobo zokuxilonga okanye ii-balancers ezisebenzayo ezenzelwe ulungelelwaniso oluthile lwepakethi yebhetri, amaqela ezobugcisa anokujonga iinkcukacha zezixhobo kwaye angenise imibuzo yobugcisa ngeqonga elisemthethweni.
Ngokudibanisa olu xilongo lwesayensi kwiinkqubo zokusebenza zemihla ngemihla, izakhiwo zolondolozo zinokunciphisa kakhulu iindleko ezingaphezulu ngelixa zinegalelo ekusebenzeni kakuhle kwezixhobo ixesha elide. Ukwandisa ubomi bokusebenza kweemodyuli zeseli ezikhoyo kunciphisa uxinzelelo lwezoqoqosho lokufumana izinto ezitshintshiweyo kwaye kunciphisa umngcipheko wemizi-mveliso onxulumene nokulahla ibhetri. Njengoko iimfuno zolawulo lwamandla kwihlabathi liphela zisiba nzima ngakumbi, ukwamkela iindlela zovavanyo eziqinileyo kuqinisekisa ukuba amashishini agcina ukuthembeka kwenkqubo, aphakamisa imida yokhuseleko, kwaye akhuphe ixabiso eliphezulu elinokwenzeka kwimpahla nganye yebhetri.
