IsiShwankathelo esipheleleyo saManqaku oLwazi lweLithium Ion yebhetri yokuzikhupha

Ngoku,iibhetri ze-lithiumzisetyenziswa ngokubanzi ngakumbi nangakumbi kwizixhobo ezahlukeneyo zedijithali ezifana neencwadi, iikhamera zedijithali, kunye neekhamera zedijithali zevidiyo.Ukongeza, banamathemba abanzi kwiimoto, izikhululo ezisisiseko eziphathwayo, kunyeizikhululo zamandla zokugcina amandla.Kule meko, ukusetyenziswa kweebhetri akusabonakali yodwa njengeefowuni eziphathwayo, kodwa ngakumbi ngendlela yochungechunge okanye ukuhambelana.iipakethi zebhetri.

Umthamo kunye nobomi bepakethi yebhetri ayihambelani kuphela nebhetri enye, kodwa inxulumene nokuhambelana phakathi kwebhetri nganye.Ukungaguquguquki kakubi kuya kuchaphazela 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.

Izizathu eziphambili zokuzikhupha ngokwazo zezi: ukuvuza kwangaphakathi kwe-elektroniki okubangelwa yi-electronic conduction partial conduction of the electrolyte okanye ezinye iisekethe ezimfutshane zangaphakathi;ngenxa yokungakhuseleki kakuhle kweringi yokutywina yebhetri okanye igasket okanye ukungonelanga kokuchaneka phakathi kweqokobhe elikhokelayo langaphandle (i-conductor yangaphandle, ukufuma) Ukuvuza kwe-electron yangaphandle okubangelwa yi-electrode/electrolyte reaction, okufana nokuhlwa kwe-anode okanye ukuncitshiswa kwe-cathode. ngenxa ye-electrolyte kunye nokungcola;ukubola kwenxalenye yezinto ezisebenzayo ze-electrode;i-electrode ebangelwa yimveliso yokubola (izinto ezinganyibilikiyo kunye negesi ye-adsorbed) Ukugqithiswa;ukugqoka komatshini we-electrode okanye ukunyuka kokuchasana phakathi kwe-electrode kunye nomqokeleli wangoku.

Ukuzikhupha ngokwakho kuya kubangela ukuba umthamo unciphise ngexesha lenkqubo yokugcina: imoto ayikwazi ukuqaliswa emva kokupaka ixesha elide;yonke into iyinto eqhelekileyo ngaphambi kokuba ibhetri ifakwe kwisitoreji, kwaye i-voltage ephantsi okanye i-voltage ye-zero ifunyenwe xa ibhetri ithunyelwa;i-GPS yemoto ifakwe emotweni ehlotyeni kwaye isetyenziswe ixeshana ndivakalelwa kukuba amandla okanye ixesha lokusetyenziswa ngokucacileyo alanelanga, kwaye ibhetri iyadumba.

Ukuzikhupha kokungcola kwesinyithi kubangela ukuba ubukhulu be-diaphragm pore buvaleke, kwaye nokugqobhoza i-diaphragm kubangela isiphaluka esifutshane sendawo, esibeka emngciphekweni ukhuseleko lwebhetri.Umahluko omkhulu kwi-SOC unokukhokelela ngokulula kwi-overcharge kunye ne-overdischarge yebhetri.

Ngenxa yokungahambelani kokuzikhupha kweebhetri, i-SOC yeebhetri kwipakethi yebhetri iyahluka emva kokugcinwa, kwaye ukusebenza kwebhetri kuyancipha.Abathengi bahlala befumana iingxaki zokuthotywa kokusebenza emva kokuba befumene ipakethe yebhetri egcinwe ixesha elide.Xa umahluko we-SOC ufikelela malunga ne-20%, amandla ebhetri adityanisiweyo yi-60% ukuya kwi-70% kuphela eseleyo.
