Ibhethri ye-lithiumkuthiwa ayiyona inkimbinkimbi, empeleni, ayiyona inkimbinkimbi kakhulu, yathi ilula, empeleni, ayilula.Uma uhlanganyela kulo mkhakha, ngakho-ke kuyadingeka ukwazi amagama ajwayelekile asetshenziswa embonini yebhethri ye-lithium, uma kunjalo, yimaphi amagama ajwayelekile asetshenziswa embonini yebhethri ye-lithium?
Amagama ajwayelekile asetshenziswa embonini yebhethri ye-lithium
1.Izinga-Izindleko/Izinga Lokukhipha
Ibonisa ukuthi ingakanani yamanje okufanele ishaje futhi ikhishwe, ngokuvamile ebalwa njengokuphindaphinda komthamo webhethri, ngokuvamile okubizwa ngokuthi ambalwa C. Njengebhethri elinomthamo ongu-1500mAh, ishiwo ukuthi 1C = 1500mAh, uma ishajwa I-2C iphinde ikhishwe nge-current ye-3000mA, ishaja engu-0.1C futhi ukukhishwa kuyashajwa futhi kukhishwe nge-150mA.
2.OCV: Vula I-Voltage Circuit
I-voltage yebhethri ngokuvamile ibhekisela ku-voltage yegama (ebizwa nangokuthi i-voltage elinganiselwe) yebhethri ye-lithium.Amandla kagesi webhethri ajwayelekile e-lithium ngokuvamile angu-3.7V, futhi sibiza nesiteji sawo samandla kagesi ngo-3.7V.Nge-voltage ngokuvamile sibhekisela ku-voltage yesekethe evulekile yebhethri.
Uma ibhethri ingu-20 ~ 80% womthamo, i-voltage igxiliswa cishe ku-3.7V (cishe 3.6 ~ 3.9V), umthamo ophezulu kakhulu noma ophansi kakhulu, i-voltage iyahluka kakhulu.
3.Amandla/Amandla
Amandla (E) ibhethri elingawakhipha lapho lishajwa ngezinga elithile, ngo-Wh (watt amahora) noma KWh (amahora e-kilowatt), ngaphezu kwalokho 1 KWh = 1 kWh kagesi.
Umqondo oyisisekelo utholakala ezincwadini ze-physics, E=U*I*t, ephinde ilingane nomthamo webhethri ophindwe ngamandla ebhethri.
Futhi ifomula yamandla ithi, P=U*I=E/t, ebonisa inani lamandla elingakhululwa ngeyunithi ngayinye yesikhathi.Iyunithi inguW (watt) noma KW (kilowatt).
Ibhethri elinomthamo ongu-1500 mAh, isibonelo, linevoltheji yegama elingu-3.7V ngokuvamile, ngakho amandla ahambisanayo ngu-5.55Wh.
4.Ukumelana
Njengoba ukushaja nokukhishwa akukwazi ukulingana namandla afanelekile, kukhona ukumelana okuthile kwangaphakathi.Ukumelana kwangaphakathi kudla amandla futhi kuncane ukumelana kwangaphakathi kuba ngcono.
Ukumelana kwangaphakathi kwebhethri kukalwa ngama-milliohms (mΩ).
Ukumelana kwangaphakathi kwebhethri elijwayelekile kuhlanganisa ukumelana ne-ohmic kwangaphakathi kanye nokumelana kwangaphakathi okune-polarized.Ubukhulu bokumelana kwangaphakathi buthonywa yizinto zebhethri, inqubo yokukhiqiza, kanye nesakhiwo sebhethri.
5.Cycle Life
Ukushaja ibhethri nokushajwa kanye kubizwa ngokuthi umjikelezo, impilo yomjikelezo iyinkomba ebalulekile yokusebenza kwempilo yebhethri.Izinga le-IEC libeka ukuthi kumabhethri e-lithium eselula, ukukhishwa kwe-0.2C ku-3.0V kanye nokushaja kwe-1C kuya ku-4.2 V. Ngemva kwemijikelezo engu-500 ephindaphindiwe, umthamo webhethri kufanele uhlale ungaphezu kuka-60% womthamo wokuqala.Ngamanye amazwi, impilo yomjikelezo webhethri ye-lithium izikhathi ezingama-500.
Izinga likazwelonke libeka ukuthi ngemuva kwemijikelezo engama-300, umthamo kufanele uhlale ku-70% womthamo wokuqala.Amabhethri anomthamo ongaphansi kuka-60% womthamo wokuqala kufanele acatshangelwe ukulahlwa kwezinto ezilahliwe.
6.DOD: Ukujula Kokukhipha I-Dicharger
Kuchazwa njengephesenti lomthamo okhishwe ebhethrini njengephesenti lomthamo olinganiselwe.Ukujula kokukhishwa kwebhethri ye-lithium ngokuvamile, impilo yebhethri iba mfishane.
7.Amandla kagesi anqunyiwe
I-voltage yokunqamula ihlukaniswe i-voltage yokuqeda ukushaja kanye ne-voltage yokunqamula yokushajwa, okusho i-voltage lapho ibhethri ingeke ishajwe khona noma iqhubeke nokushajwa.I-voltage yokuqeda ukushaja yebhethri ye-lithium ngokuvamile ingu-4.2V kanti i-voltage yokuqeda ukushajwa ingu-3.0V.Ukushaja okujulile noma ukushajwa kwebhethri ye-lithium ngale kwe-voltage yokunqanyulwa kunqatshelwe ngokuphelele.
8.Ukuzikhipha
Isho izinga lokuncipha komthamo webhethri ngesikhathi sokulondoloza, elichazwe njengokuncipha kwephesenti kokuqukethwe ngeyunithi ngayinye yesikhathi.Izinga lokuzikhipha ngokwakho lebhethri le-lithium elijwayelekile lingu-2% ukuya ku-9%/ngenyanga.
9.SOC(State of Charge)
Isho iphesenti lokushajwa okusele kwebhethri kukho konke ukushajwa okungashajwa, 0 kuya ku-100%.Ibonisa ukushajwa okusele kwebhethri.
10.Amandla
Isho inani lamandla angatholwa ku-lithium yebhethri ngaphansi kwezimo ezithile zokukhishwa.
Ifomula kagesi ithi Q=I*t kuma-coulombs futhi iyunithi yomthamo webhethri icaciswa ngokuthi Ah (amahora ampere) noma mAh (amahora ama-milliampere).Kusho ukuthi ibhethri elingu-1AH lingashajwa ihora elingu-1 ngamandla angu-1A uma selishajwe ngokugcwele.
