Ithiyori yokushaja nokukhipha i-Lithium & nomklamo wendlela yokubala kagesi
2.4 Imitha kagesi ye-Dynamic voltage algorithm
I-algorithm ye-algorithm ye-algorithm eguquguqukayo ingakwazi ukubala isimo sokushajwa kwebhethri ye-lithium kuphela ngokuya nge-voltage yebhethri.Le ndlela ilinganisela ukukhuphuka noma ukuncipha kwesimo sokushaja ngokomehluko phakathi kwevoltheji yebhethri nevolthi yebhethri evula isekethe.Ulwazi lwe-Dynamic voltage lungalinganisa ngempumelelo indlela ibhethri le-lithium eliziphatha ngayo, bese linquma i-SOC (%), kodwa le ndlela ayikwazi ukulinganisa inani lomthamo webhethri (mAh).
Indlela yayo yokubala isekelwe kumehluko oguquguqukayo phakathi kwevoltheji yebhethri kanye nevolthi yesiyingi evulekile, ngokusebenzisa i-algorithm ephindaphindayo ukubala ukwanda noma ukwehla ngakunye kwesimo sokushaja, ukuze kulinganiswe isimo sokushaja.Uma kuqhathaniswa nesixazululo semitha ye-coulomb, i-coulometer ye-voltage eguqukayo ye-algorithm ngeke iqongelele amaphutha ngesikhathi namanje.I-coulometer ye-coulometric ivamise ukuba nesilinganiso esingalungile sesimo sokushaja ngenxa yephutha lamanje lezinzwa kanye nokuzikhipha kwebhethri.Ngisho noma iphutha lamanje lenzwa lilincane kakhulu, ikhawunta ye-coulomb izoqhubeka iqongelela iphutha, futhi iphutha eliqoqiwe lingasuswa kuphela ngemva kokushajwa okugcwele noma ukukhipha ngokuphelele.
I-algorithm ye-Dynamic voltage Imitha kagesi ilinganisela isimo sokushajwa kwebhethri kuphela ngolwazi lwe-voltage;Ngenxa yokuthi ayilinganiswa ngolwazi lwamanje lwebhethri, ngeke iqongelele amaphutha.Ukuze kuthuthukiswe ukunemba kwesimo sokushaja, i-algorithm ye-voltage eguquguqukayo idinga ukusebenzisa idivayisi yangempela ukulungisa amapharamitha we-algorithm elungiselelwe ngokuya ngejika langempela levolthi yebhethri ngaphansi kwesimo sokushajwa okugcwele nokukhipha ngokuphelele.
Umfanekiso 12. Ukusebenza kwemitha kagesi ye-algorithm ye-voltage eguquguqukayo kanye nokwenza ngcono
Okulandelayo ukusebenza kwe-algorithm ye-voltage eguqukayo ngaphansi kwamazinga ahlukene okukhipha.Kungabonakala emfanekisweni ukuthi isimo sayo sokukhokhisa ukunemba sihle.Kungakhathaliseki izimo zokukhishwa kwe-C/2, C/4, C/7 kanye ne-C/10, iphutha eliphelele le-SOC lale ndlela lingaphansi kuka-3%.
Umfanekiso 13. Isimo senkokhelo ye-algorithm ye-voltage eguquguqukayo ngaphansi kwamazinga ahlukene okukhipha
Isithombe esingezansi sibonisa isimo sokushaja kwebhethri ngaphansi kwesimo sokushaja okufushane kanye nokukhishwa okufushane.Iphutha lesimo sokukhokhiswa lisencane kakhulu, futhi iphutha elikhulu lingama-3%.
Umfanekiso 14. Isimo sokushajwa kwe-algorithm ye-voltage eguquguqukayo esimweni sokushaja okufushane kanye nokukhishwa okufushane kwebhethri.
Uma kuqhathaniswa ne-coulomb metering coulometer, evame ukubangela isimo sokushaja esingalungile ngenxa yephutha lamanje lokuzwa kanye nokuzikhipha kwebhethri, i-algorithm ye-voltage eguquguqukayo ayiqoqi iphutha ngesikhathi namanje, okuyinzuzo enkulu.Ngenxa yokuthi alukho ulwazi lwamanje olukhokhiswayo/lokukhipha, i-algorithm ye-voltage eguquguqukayo inokunemba okumpofu kwesikhashana esifushane kanye nesikhathi sokuphendula esinensayo.Ngaphezu kwalokho, ayikwazi ukulinganisa umthamo wokushaja ogcwele.Kodwa-ke, isebenza kahle ngokunemba kwesikhathi eside ngoba amandla ombane webhethri ekugcineni azokhombisa ngokuqondile isimo sayo sokushaja.
