Okwangoku, iibhetri ze-lithium zisetyenziswa ngokubanzi kwizixhobo ezahlukeneyo zedijithali ezifana neencwadi, iikhamera zedijithali, kunye neekhamera zevidiyo zedijithali. Ukongeza, banamathemba abanzi kwiimoto, izikhululo ezisisiseko eziphathwayo, kunye nezikhululo zamandla zokugcina amandla. Kule meko, ukusetyenziswa kweebhetri akubonakali yodwa njengeefowuni eziphathwayo, kodwa ngakumbi ngendlela yochungechunge okanye iipakethi zebhetri ezifanayo.
Umthamo kunye nobomi bebhetri ipakethe ayinxulumananga kuphela nebhetri enye, kodwa inxulumene nokuhambelana phakathi kwebhetri nganye. Ukungaguquguquki kakubi kuya kutsala kakhulu ukusebenza kwebhetri. Ukuhambelana kokuzikhupha yinxalenye ebalulekileyo yezinto ezichaphazelayo. Ibhetri ene-self-discharge engahambelaniyo iya kuba nentlukwano enkulu kwi-SOC emva kwexesha lokugcina, eliya kuchaphazela kakhulu amandla kunye nokhuseleko.
Kutheni ukukhutshwa ngokwakho kwenzeka?
Xa ibhetri ivuliwe, ukusabela okungentla akwenzeki, kodwa amandla aya kuncipha, nto leyo ebangelwa ukukhutshwa kwebhetri. Izizathu eziphambili zokuzikhupha ngokwakho zezi:
a. Ukuvuza kwe-electron yangaphakathi okubangelwa ukuqhutyelwa kwe-electron yendawo ye-electrolyte okanye ezinye iisekethe ezimfutshane zangaphakathi.
b. Ukuvuza kombane wangaphandle ngenxa yokugqunyelelwa okulambathayo kwetywina lebhetri okanye iigaskithi okanye ukungonelanga kokumelana namaqokobhe okukhokela angaphandle (ii-conductor zangaphandle, ukufuma).
c. Ukuphendulwa kwe-electrode / electrolyte, njengokubola kwe-anode okanye ukunciphisa i-cathode ngenxa ye-electrolyte, ukungcola.
d. Ukubola kwenxalenye yezinto ezisebenzayo ze-electrode.
e. Ukugqithiswa kwee-electrodes ngenxa yeemveliso zokubola (i-insolubles kunye neegesi ze-adsorbed).
f. I-electrode igqitywe ngomatshini okanye ukuchasana phakathi kwe-electrode kunye nomqokeleli wangoku uba mkhulu.
Impembelelo yokuzikhupha
Ukuzikhupha ngokwakho kukhokelela ekunciphiseni umthamo ngexesha lokugcinwa.Iingxaki ezininzi eziqhelekileyo ezibangelwa kukuzikhupha ngokugqithisileyo:
1. Imoto imiswe ixesha elide kwaye ayinakuvuswa;
2. Ngaphambi kokuba ibhetri ifakwe kwisitoreji, i-voltage kunye nezinye izinto ziqhelekileyo, kwaye kufunyenwe ukuba i-voltage iphantsi okanye i-zero xa ithunyelwa;
3. Ehlotyeni, ukuba i-GPS yemoto ibekwe emotweni, amandla okanye ixesha lokusebenzisa ngokuqinisekileyo liya kunganelanga emva kwexesha elithile, nokuba ibhetri iqhuma.
Ukuzikhupha ngokwakho kukhokelela ekwandeni kweeyantlukwano ze-SOC phakathi kweebhetri kunye nokunciphisa umthamo webhetri
Ngenxa yokungahambelani kokuzikhupha kwebhetri, i-SOC yebhetri kwipakethi yebhetri iya kuba yinto eyahlukileyo emva kokugcinwa, kwaye ukusebenza kwebhetri kuya kuncipha. Abathengi bahlala befumana ingxaki yokuthotywa kokusebenza emva kokufumana ipakethi yebhetri egcinwe ixesha elithile. Xa umahluko we-SOC ufikelela malunga ne-20%, umthamo webhetri edibeneyo yi-60% ~ 70% kuphela.
Indlela yokusombulula ingxaki yeeyantlukwano ezinkulu zeSOC ezibangelwa ukuzikhupha?
Ngokulula, Sidinga kuphela ukulinganisa amandla ebhetri kwaye sidlulisele amandla e-high-voltage cell kwi-low-voltage cell. Ngoku kukho iindlela ezimbini: ukulinganisa okungenziwayo kunye nokulungelelanisa okusebenzayo
Ukulinganisa okungahambiyo kukudibanisa isixhasi sokulinganisa ngokunxuseneyo nebhetri nganye. Xa iseli ifikelela kwi-overvoltage kwangaphambili, ibhetri isenokuthi itshajwe kwaye itshaje ezinye iibhetri ezine-voltage ephantsi. Ukusebenza kakuhle kwale ndlela yokulinganisa ayiphezulu, kwaye amandla alahlekileyo alahlekile ngendlela yokushisa. Ukulinganisa kufuneka kuqhutywe kwimodi yokutshaja, kwaye ukulinganisa ngoku ngokuqhelekileyo yi-30mA ukuya kwi-100mA.
Isilinganisi esisebenzayongokubanzi ibhalansisa ibhetri ngokudlulisa amandla kwaye idlulisela amandla eeseli ezinombane ogqithileyo kwezinye iiseli ezinombane ophantsi. Le ndlela yokulinganisa inokusebenza okuphezulu kwaye inokulinganisa kuzo zombini iintlawulo kunye nokukhupha amazwe. Ukulinganisa kwayo okwangoku kuninzi ngokuphindwe kabini kune-equalization yangoku, ngokubanzi phakathi kwe-1A-10A.
