1. Isingeniso sebhethri ye-lithium-ion
1.1 Isimo Sokukhokhiswa (SOC)
Isimo sokushaja singachazwa njengesimo samandla kagesi atholakalayo ebhethrini, ngokuvamile evezwa njengephesenti.Ngenxa yokuthi amandla kagesi atholakalayo ayahlukahluka ngokushaja nokukhipha amandla, izinga lokushisa nokuguga, incazelo yesimo sokushaja nayo ihlukaniswe yaba izinhlobo ezimbili: I-Absolute State-Of-Charge (ASOC) kanye Ne-Relative State-Of-Charge (RSOC) .
Ngokuvamile, ububanzi besimo sokushajwa obuhlobene bungu-0% - 100%, kuyilapho bungu-100% uma ibhethri selishajwe ngokugcwele kanye no-0% uma selishajwe ngokugcwele.Isimo sokushajwa esiphelele yinani eliyireferensi elibalwa ngokwenani eliklanyelwe lomthamo ongashintshi lapho ibhethri lakhiwe.Isimo sokushajwa esiphelele sebhethri elisha eligcwaliswe ngokuphelele ngu-100%;Ngisho noma ibhethri yokuguga ishajwe ngokugcwele, ayikwazi ukufinyelela ku-100% ngaphansi kwezimo ezihlukene zokushaja nokukhipha.
Isibalo esilandelayo sibonisa ubudlelwano phakathi kwamandla kagesi namandla ebhethri ngamanani ahlukene okukhipha.Uma izinga lokuphuma liphakeme, umthamo webhethri uyancipha.Uma izinga lokushisa liphansi, umthamo webhethri nawo uzokwehla.
Umfanekiso 1. Ubudlelwano phakathi kwamandla kagesi namandla ngaphansi kwamazinga ahlukene okukhipha kanye namazinga okushisa
1.2 I-Voltage yokushaja enkulu
I-voltage yokushaja ephezulu ihlobene nokwakheka kwamakhemikhali nezici zebhethri.I-voltage yokushaja yebhethri ye-lithium ivamise ukuba ngu-4.2V no-4.35V, futhi amanani kagesi we-cathode nezinto ze-anode azohluka.
1.3 Ishajwe Ngokugcwele
Uma umehluko phakathi kwevoltheji yebhethri kanye ne-voltage yokushaja ephezulu ingaphansi kuka-100mV futhi amandla okushaja ancipha abe ku-C/10, ibhethri ingathathwa njengeshajwe ngokugcwele.Izimo zokushaja ngokugcwele ziyahlukahluka nezici zebhethri.
Isibalo esingezansi sibonisa ijika lesici sokushaja ibhethri le-lithium.Uma i-voltage yebhethri ilingana ne-voltage yokushaja ephezulu futhi amandla okushaja ehliselwa ku-C/10, ibhethri lithathwa njengelishajwe ngokugcwele.
Umfanekiso 2. Ijika lesici sokushaja ibhethri le-lithium
1.4 I-voltage encane yokukhipha
I-voltage encane yokukhipha ingachazwa nge-voltage yokukhipha okunqanyuliwe, okuvame ukuba yi-voltage lapho isimo sokushaja singu-0%.Leli nani lamandla kagesi alilona inani elinqunyiwe, kodwa liyashintsha ngomthwalo, izinga lokushisa, idigri yokuguga noma ezinye izici.
1.5 Ukukhishwa Okugcwele
Uma i-voltage yebhethri ingaphansi noma ilingana ne-voltage encane yokukhipha, ingabizwa ngokuthi ukukhishwa okuphelele.
1.6 Izinga lokushaja nokukhipha (C-Rate)
Izinga lokushajwa liwumfanekiso wamanje wokushajwa okuhlobene nomthamo webhethri.Isibonelo, uma usebenzisa i-1C ukukhipha ihora elilodwa, kuhle, ibhethri izophuma ngokuphelele.Amazinga ahlukene okukhipha imali azophumela kumthamo osebenzisekayo ohlukile.Ngokuvamile, ukuphakama kwezinga lokushaja, liba lincane umthamo otholakalayo.
1.7 Impilo yomjikelezo
Inani lemijikelezo libhekisela enanini lokushaja okuphelele nokuphuma kwebhethri, elingalinganiswa ngomthamo wangempela wokukhipha kanye nomthamo wokuklama.Uma umthamo wokukhipha oqoqiwe ulingana nomthamo wokuklama, inani lemijikelezo lizoba munye.Ngokuvamile, ngemva kwemijikelezo engu-500 yokushajwa, umthamo webhethri elishajwe ngokugcwele uzokwehla ngo-10% ~ 20%.
Umfanekiso 3. Ubudlelwano phakathi kwezikhathi zomjikelezo namandla ebhethri
1.8 Ukuzikhulula
Ukuzikhipha kwawo wonke amabhethri kuzokhula ngokunyuka kwezinga lokushisa.Ukuzikhipha ngokwakho empeleni akulona iphutha lokukhiqiza, kodwa izici zebhethri ngokwayo.Kodwa-ke, ukwelashwa okungalungile ohlelweni lokukhiqiza kuzophinde kubangele ukwanda kokuzikhulula.Ngokuvamile, izinga lokuzikhulula lizophindwa kabili lapho izinga lokushisa lebhethri likhuphuka ngo-10 ° C. Umthamo wokuzikhulula wamabhethri e-lithium-ion cishe u-1-2% ngenyanga, kanti owamabhethri asekelwe ku-nickel ahlukahlukene angu-10- 15% ngenyanga.
Umfanekiso 4. Ukusebenza kwezinga lokuzikhulula kwebhethri ye-lithium emazingeni okushisa ahlukene
