Intshayelelo:
Iibhetri zeLithiumziya zithandwa kakhulu kwizicelo ukusuka kwizithuthi zombane ukuya kwiinkqubo zokugcina amandla avuselelekayo. Nangona kunjalo, enye yeengxaki ngeebhetri ze-lithium yinto enokwenzeka yokungalingani kweeseli, ezinokuthi zikhokelela ekunciphiseni ukusebenza kunye nokunciphisa ubomi. Apha kulapho aibhetri ye-lithium yokulinganisauyadlala. Kweli nqaku, siza kuphonononga ukubaluleka kokulinganisa ibhetri ye-lithium kunye nendlela asebenza ngayo ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide kwenkqubo yakho yebhetri ye-lithium.
Yintoni ibhetri ye-lithium yokulinganisa?
I-lithium ibhetri ye-equalizer sisixhobo esenzelwe ukulinganisa i-voltage kunye ne-state of charge (SOC) yeeseli ezizimeleyo ngaphakathi kwepakethi yebhetri ye-lithium. Oku kubaluleke kakhulu kwiinkqubo ezinkulu zebhetri apho iiseli ezininzi ziqhagamshelwe kuthotho okanye ngokuhambelanayo. Isilinganisi sisebenza ngokusabalalisa amandla kwakhona phakathi kweeseli ukuqinisekisa ukuba zonke zisebenza kwi-voltage efanayo kunye ne-SOC, ngaloo ndlela ukwandisa umthamo kunye nokusebenza kakuhle kwebhetri yepakethe.
Isebenza njani ibhetri yelithium yokulinganisa?
Izilinganisi zebhetri yeLithiumsebenzisa iindlela ezahlukeneyo ukulungelelanisa iiseli ngaphakathi kwipakethi yebhetri. Enye indlela eqhelekileyo kukusebenzisa i-passive balancing, ebandakanya ukuchitha amandla agqithisileyo ukusuka kwibhetri yombane ophezulu ukuya kwibhetri yombane ophantsi ngokusebenzisa isixhasi okanye enye icandelo lokwenziwa. Le nkqubo inceda ukulinganisa amanqanaba ombane azo zonke iiseli, ukuthintela iiseli zomntu ukuba zingatshaji okanye zikhuphe ngokugqithisileyo.
Enye indlela kukulinganisa okusebenzayo, okubandakanya ukusebenzisa iisekethe ze-elektroniki ezisebenzayo ukuhambisa amandla phakathi kweeseli. Ezi sekethe zibeka iliso kwi-voltage yeseli nganye kwaye zilawule ukuhamba kwamandla ukuqinisekisa ukuba zonke iiseli zihlala zilungelelene. Ulungelelwaniso olusebenzayo luhlala lusebenza ngakumbi kunokulinganisa nje kwaye lunokunceda ukugcina impilo iyonke kunye nokusebenza kwebhetri.
Ukubaluleka kokulinganisa ibhetri ye-lithium
Ukungalingani kweeseli kwipakethi yebhetri ye-lithium kunokuchaphazela kakubi ukusebenza kunye nokhuseleko. Xa iibhetri zingalungelelaniswanga, ezinye iiseli zinokutshajwa kakhulu ngelixa ezinye zinokutshajwa kancinane, nto leyo ekhokelela kwiingozi zokhuseleko ezifana nokuncipha komthamo, ukonakaliswa okukhawulezileyo, kunye nokubaleka kwe-thermal. Izilinganisi zebhetri yeLithium zinceda ukunciphisa le miba ngokuqinisekisa ukuba zonke iiseli zisebenza ngaphakathi kwamandla ombane afanelekileyo kunye noluhlu lweSOC, ngaloo ndlela bandisa ubomi bepakethi yebhetri kunye nokunciphisa umngcipheko wokusilela.
Ukongeza ekuphuculeni ukusebenza kunye nokhuseleko, i-lithium ibhetri elinganayo inceda ukuphucula ukusebenza kakuhle kwenkqubo yebhetri. Ngokugcina iiseli zilungelelene, i-equalizer inceda ukwandisa umthamo okhoyo wepakethi yebhetri, okukhokelela kwixesha elide lokugijima kunye nokwandisa amandla okugcina amandla. Oku kubaluleke kakhulu kwizicelo ezifana neenqwelo zombane kunye nokugcinwa kwamandla avuselelekayo, apho ukusebenza okuthembekileyo kweenkqubo zebhetri kubaluleke kakhulu.
Ukongeza, usebenzisa aibhetri ye-lithium yokulinganisainokonga iindleko ekuhambeni kwexesha. Ngokuthintela ukuthotywa kwangaphambili kunye nokuqinisekisa ukusebenza kwebhetri efanayo, isidingo sokutshintshwa kwangaphambi kwexesha kunye nokugcinwa kuncitshisiwe, ekugqibeleni kunciphisa iindleko ezipheleleyo zobunini beenkqubo zebhetri ye-lithium.
Ukuqukumbela
n isishwankathelo, ibhetri ye-lithium yokulinganisa idlala indima ebalulekileyo ekugcineni impilo kunye nokusebenza kwepakethi yebhetri ye-lithium. Ngokulinganisa ngokusebenzayo i-voltage kunye ne-SOC yeeseli zomntu ngamnye, ezi zixhobo zinceda ukwandisa ukusebenza kakuhle, ixesha elide kunye nokhuseleko lweenkqubo zebhetri ze-lithium. Njengoko imfuno yeebhetri ze-lithium iqhubeka ikhula kuwo wonke amashishini, ukubaluleka kokulinganisa iiseli ezisebenzayo ngesilinganisi akukwazi ukugqithiswa. Ukuphumezaibhetri ye-lithium elinganayokufuneka ibe yinto ephambili kubavelisi, abahlanganisi kunye nabasebenzisi bokugqibela ukuvula amandla apheleleyo ezisombululo zabo zokugcina amandla.
