2.4 Imitha yombane yombane oguquguqukayo

I-voltage ye-algorithm coulometer eguquguqukayo inokubala imeko yentlawulo yebhetri ye-lithium kuphela ngokombane webhetri.Le ndlela iqikelela ukonyuka okanye ukuhla kwemo yentlawulo ngokomahluko phakathi kombane webhetri kunye nombane webhetri ovulelekileyo wesekethe.Ulwazi lwamandla ombane oguqukayo lunokulinganisa ngokufanelekileyo ukuziphatha kwebhetri ye-lithium, kwaye emva koko inqume i-SOC (%), kodwa le ndlela ayikwazi ukuqikelela ixabiso lebhetri umthamo (mAh).

Indlela yayo yokubala isekelwe kumahluko oguquguqukayo phakathi kombane webhetri kunye nombane ovulekileyo wesekethe, ngokusebenzisa i-algorithm ephindaphindayo ukubala ukunyuka okanye ukuncipha kwemeko yentlawulo, ukuqikelela imeko yentlawulo.Xa kuthelekiswa nesisombululo semitha ye-coulomb, i-coulometer ye-voltage eguquguqukayo ye-algorithm coulometer ayiyi kuqokelela iimpazamo kunye nexesha kunye nangoku.I-coulometer ye-coulometric idla ngokuba noqikelelo olungachanekanga lwemeko yentlawulo ngenxa yempazamo yangoku yokuva kunye nokuzikhupha kwebhetri.Nangona impazamo yangoku yokuva incinci kakhulu, i-counter ye-coulomb iya kuqhubeka iqokelela impazamo, kwaye impazamo eqokelelweyo inokupheliswa kuphela emva kokutshaja ngokupheleleyo okanye ukukhutshwa ngokupheleleyo.

I-algorithm yombane we-Dynamic Imitha yombane iqikelela imeko yentlawulo yebhetri kuphela kwingcaciso yombane;Ngenxa yokuba ayiqikelelwa ngolwazi lwangoku lwebhetri, ayiyi kuqokelela iimpazamo.Ukuphucula ukuchaneka kobume bentlawulo, i-algorithm ye-voltage eguquguqukayo kufuneka isebenzise isixhobo sangempela ukulungelelanisa iiparitha ze-algorithm ephuculweyo ngokweyona ndlela yombane webhetri phantsi kwemeko yentlawulo epheleleyo kunye nokukhutshwa okupheleleyo.

Umzobo 12. Ukusebenza kwemitha yombane ye-algorithm yombane oguquguqukayo kunye nokufumana ukulungiswa

Oku kulandelayo kukusebenza kwe-algorithm yombane oguquguqukayo phantsi kwamazinga ahlukeneyo okukhutshwa.Ingabonwa kumzobo ukuba imeko yayo yokuchaneka kwentlawulo ilungile.Kungakhathaliseki ukuba iimeko zokukhutshwa kweC / 2, C / 4, C / 7 kunye neC / 10, impazamo ye-SOC iyonke yale ndlela ingaphantsi kwe-3%.

Umzobo 13. Imeko yentlawulo ye-algorithm ye-voltage eguquguqukayo phantsi kwamazinga ahlukeneyo okukhutshwa

Umfanekiso ongezantsi ubonisa imeko yentlawulo yebhetri phantsi kwemeko yentlawulo emfutshane kunye nokukhutshwa okufutshane.Impazamo yemeko yentlawulo isencinci kakhulu, kwaye impazamo enkulu yi-3% kuphela.

Umzobo 14. Ubume bentlawulo ye-algorithm yombane oguqukayo kwimeko yentlawulo emfutshane kunye nokukhutshwa okufutshane kwebhetri.

Xa kuthelekiswa ne-coulomb metering coulometer, edla ngokubangela imeko engachanekanga yentlawulo ngenxa yempazamo yangoku yokuziva kunye nokuzikhupha kwebhetri, i-algorithm ye-voltage eguquguqukayo ayiqokeleli impazamo kunye nexesha kunye nangoku, okuyinzuzo enkulu.Ngenxa yokuba akukho ntlawulo / ukukhutshwa kolwazi lwangoku, i-algorithm yombane oguqukayo inokuchaneka kwexesha elifutshane kunye nexesha lokuphendula elicothayo.Ukongeza, ayinakuqikelela umthamo ogcweleyo wentlawulo.Nangona kunjalo, iqhuba kakuhle ngokuchaneka kwexesha elide kuba amandla ombane ebhetri ekugqibeleni aya kubonisa ngokuthe ngqo imeko yawo yentlawulo.
