Izicelo zanamhlanje zoshishino nezorhwebo zixhomekeke ngakumbi kwiindlela ezintsonkothileyo ze-lithium-ion kunye ne-lead-acid energy kwimisebenzi yamandla. Ingcamango ephosakeleyo eqhelekileyo kubunjineli bokugcina amandla kukuba ipakethi yebhetri enamandla aphezulu isebenza nje njengoluhlu oludibeneyo lweeseli nganye nganye. Ngokwenyani, iiseli ze-electrochemical ngokwemvelo zibonisa umahluko omncinci kukumelana kwangaphakathi, amazinga okuzikhupha, kunye namandla okusebenza ngenxa yokunyamezelana kwemveliso kunye ne-gradients yobushushu bendawo. Ukunciphisa oku kungangqinelani, abaqhubi bemizi-mveliso basebenzisa izixhobo zolawulo lwamandla ezikhethekileyo ezenziwe yiAmandla eHeltec umphuhlisi ophambili weenkqubo zokulinganisa iiseli. Kwimijikelo emininzi yokutshaja nokukhupha, umahluko omncinci weeseli ngamnye uyakhula, nto leyo ebangela into eyaziwa ngokuba yi "barrel effect," apho eyona seli ibuthathaka ilawula amandla asetyenziswayo kwaye inciphise ukusebenza kwendibano yonke. Ngelixa iinkqubo zokhuseleko ezisemgangathweni zijonga olu qwalaselo, i-battery equalizer ekhethekileyo isebenza njengecandelo elibalulekileyo lokugcinwa kunye nokwenza ngcono ukusebenza eliyilelwe ukususa la mahluko angaphakathi, ukuqinisekisa ukusebenza kakuhle kwexesha elide.
Iindima ezahlukileyo zeeModyuli zokulinganisela kunye neenkqubo zoLawulo lweeBhetri
Ukuze kuphuculwe ii-arrays zamandla amakhulu, kubalulekile ukwahlula imida ethile yokusebenza yeNkqubo yoLawulo lweBhetri esemgangathweni (i-BMS) kuleyo yemodyuli yokulinganisela ezinikeleyo. I-BMS eqhelekileyo isebenza ngokuyintloko njengendlela yokhuseleko kunye nokukhusela, ibeka esweni iiparameter ezifana nokutshaja kakhulu, ukukhupha ngaphezulu, umbane ogqithisileyo, kunye neemeko zesekethe emfutshane ukuthintela ukungaphumeleli okukhulu. Nangona kunjalo, amandla okulinganisela angaphakathi eeyunithi ezininzi ze-BMS ezisemgangathweni awenzi nto, axhomekeke kwii-resistor ezincinci ukukhupha amandla agqithisileyo njengobushushu, zihlala zilinganiselwe kwi-currents ephantsi ye-30 ukuya kwi-50 milliamperes.
Ngokwahlukileyo koko, imodyuli yokulinganisela yangaphandle isebenza njenge-co-processor ejolise kakhulu, ephucula ukusebenza esebenza kunye ne-BMS ekhuselayo. Endaweni yokutshintsha inkqubo yokhuseleko, i-balancer ezinikeleyo igxila kuphela ekuthinteleni ukungangqinelani kwe-voltage kwiiseli eziqhagamshelwe kuthotho. Ngokuqhubeka nokudlulisela amandla ukusuka kwiiseli ze-voltage ephezulu ukuya kwiiseli ze-voltage ephantsi, imodyuli igcina amanqanaba afanayo e-state-of-charge kuyo yonke iphakheji. Olu lawulo olusebenzayo luthintela iiseli nganye ukuba zingafikeleli ngaphambi kwexesha kwimida yokusika i-voltage ephantsi, ngaloo ndlela ivula amandla ebengasayi kufikeleleka ngenxa yokuwohloka kweeseli zasekuhlaleni.
Iindlela Zokusebenza kunye Nokuqinisekiswa Kokusebenza Kokulingana Okusebenzayo
Itekhnoloji yokulungisa ephucukileyo, njengezixhobo ezikhethekileyo eziphuhliswe yiChengdu Heltec Energy Technology Co., Ltd., isebenzisa ukudluliselwa kwamandla asebenzayo okusebenzayo okuphezulu ukulungisa ukungangqinelani kweeseli. Endaweni yokuchitha amandla agqithisileyo njengamandla obushushu, ii-equalizer ezisebenzayo eziphambili zisebenzisa ii-microcontrollers ezidityaniswe ne-capacitive okanye inductive energy-transfer architectures ukuze ziphinde zibeke itshaja ngendlela eguquguqukayo kuyo yonke iphakheji.
Uhlalutyo lweenkqubo zokulinganisela ezizimeleyo ezivela kwiHeltec Energy lubonisa iindlela ezahlukeneyo zobugcisa ezinegalelo ekuvuselelweni kwepakethi okuqinisekisiweyo:
● Ukubeka esweni ngokuchanekileyo:Ukudityaniswa kwee-microcontrollers zeMicrochip ezikhawulezayo kwenza ukuba i-voltage ifumaneke ngexesha langempela ngokuchaneka kwesampuli ye-1 millivolt kuluhlu olubanzi lokulinganisa lwe-1V ukuya kwi-5V. Esi sisombululo sichanekileyo sivumela inkqubo ukuba ibone ukuphambuka kwe-micro-volt ngaphambi kokuba inyuke ibe ziingxaki ezibalulekileyo zokusebenza.
● Ukudluliselwa kwamandla okungasasazekiyo:Ngokusebenzisa iisekethe ezisebenzisa amandla okanye ezisebenzisa amandla amakhulu, ezi nkqubo zinceda ukuba i-equalization currents iqhubekeke ifikelela kwi-15 amperes kwiimodeli ezithile. Okubaluleke kakhulu, le ndlela isebenza ngokuzimeleyo kwindawo esecaleni kweseli, oko kuthetha ukuba amandla anokudluliselwa ngokufanelekileyo ukusuka kwiseli yokuqala ukuya kwiseli yokugqibela kwintambo ende yochungechunge ngaphandle kokuqokelelana kobushushu bendawo.
● I-Chemistry eguquguqukayo kunye nokuhambelana kwesakhiwo:Izixhobo zokulinganisela zanamhlanje zibonelela ngenkxaso yendalo kwiitopoloji ezintsonkothileyo eziqala kwi-2S ukuya kwi-24S okanye nakwiimeko ze-32S. Oku kuguquguquka kuqinisekisa ukuhambelana okungenamthungo kwiiprofayili ezininzi zeekhemikhali, kubandakanya iLithium Nickel Manganese Cobalt Oxide (NCM), iLithium Iron Phosphate (LFP), kunye neLithium Titanate (LTO).
● Iimpawu zokusebenza kunye nokhuseleko lweendlela ezininzi:Iimodeli eziphambili zineendlela zokulinganisa ezizenzekelayo, ezenziwe ngesandla, okanye ezitshajiweyo, ezincediswa zi-alamu ezizenzekelayo zokuvala kunye nee-alamu ezivakalayo xa umsebenzi ugqityiwe. Ukuqina komzimba kuphuculwa ngeengubo ezikhethekileyo zokukhusela ezikhusela iisekethe zangaphakathi kumswakama, uthuli, kunye nokubola kweekhemikhali, ngelixa izikrini ze-LCD ezidibeneyo kunye neendawo zonxibelelwano ezingenazingcingo zivumela ukulandelelwa kokuxilongwa okukude.
Ukusebenzisa i-equalization ejolise ngqo kunciphisa ukuwohloka kwesakhiwo sepakethe. Ukususa ukungalingani kwe-voltage kulungisa imeko yetshaja kuzo zonke iiseli, kubuyisela amandla avaliweyo ngenxa yokunqunyulwa kwe-voltage ngaphambi kwexesha. Oku kwandisa ngokuthe ngqo ubunzulu bokukhupha, kunciphisa ukwahluka kokumelana kwangaphakathi, kwaye kunciphise ukufiphala kwe-cyclic capacity, ngaloo ndlela kwandisa ubomi bexesha lokusebenza kwe-asethi yemizi-mveliso.
Amaxesha okusetyenziswa asekelwe kwiZigaba zokubola kwe-Electrochemical
Ukuchonga ixesha elifanelekileyo lokudibanisa i-battery balancer ezinikeleyo kuxhomekeke kakhulu kwisigaba esithile sokusebenza kunye nezinto ezibangela uxinzelelo lokusingqongileyo kwenkqubo yamandla. Kwiipakethi zebhetri ezisandula ukuhlanganiswa ezisebenza kwimijikelo yokusebenza emifutshane, engaphantsi koxinzelelo, umahluko wangaphakathi weseli uhlala uncinci, okuvumela inkqubo ephambili ukuba ilawule uzinzo okwethutyana ngaphandle kokungenelela kwangaphandle kwangoko.
Nangona kunjalo, idatha yasentsimini eqokelelwe yiChengdu Heltec Energy Technology Co., Ltd. ibonisa ukuba ukuhlanganiswa kuyacetyiswa kakhulu emva kweenyanga ezintandathu zenkonzo eqhubekayo, okanye xa ukungalingani kweeseli nganye kulinganiswa kudlula ii-millivolts ezingama-30. Ukulungiswa kuba yinto engxamisekileyo ngakumbi kwizicelo ezinzima ezifana neenethiwekhi zokugcina amandla ezizinzileyo, izixhobo zamandla ezimbonini ezinzima, kunye neenqanawa zothutho zombane. Ngaphezu koko, xa iinkqubo zokulungisa zifuna ukuxuba iiseli ezintsha kunye nezinto ezindala, ezingahambelaniyo, iifreyimu zokulinganisela ezingasebenziyo ziyasilela ukucubungula umahluko omkhulu wevolthi. Kule meko ifunwa kakhulu, ukulingana okusebenzayo kuthintela ukuwohloka kobushushu bendawo ngokukhawuleza kunye nokuthatha umhlala-phantsi wepakethi ngaphambi kwexesha.
Isiphelo
Iimodyuli zokulinganisela ezinikezelweyo zisebenza njengeziseko ezibalulekileyo zokwandisa ukuhambelana, ukhuseleko, kunye nexesha elide lokusebenza kwiibhetri zemizi-mveliso. Ngokunciphisa ngokukhutheleyo ukungangqinelani kweeseli okukhokelela ekulahlekelweni kwamandla kwangoko, ezi nkqubo zikhusela utyalo-mali olukhulu kwitekhnoloji yamandla. Ukukhetha i-hardware efanelekileyo yokulinganisa esebenzayo kufuna ukuthelekisa uqwalaselo oluthile lwechungechunge kunye nekhemistri esisiseko yephakheji yebhetri nezixhobo zolondolozo ezijolise kuzo.
