Kuyini ukujula kokukhishwa kwamabhethri e-lithium-ion nokuthi ungakuqonda kanjani?

Kunemibono emibili mayelana nokujula kokukhishwa kweamabhethri e-lithium.Enye ibhekisela ekutheni i-voltage yehla engakanani ngemva kokuba ibhethri selikhishiwe isikhathi esithile, noma ukuthi ingakanani i-terminal voltage (okungaleso sikhathi lapho ngokuvamile ikhishwa khona).Enye ibhekisela kumthamo webhethri, okuyimalini ekhishiwe.

Ibhethri ye-lithium-ionukujula kokukhishwa, izici ezikhawulela ukujula kokukhishwa kwamabhethri e-lithium-ion.Njengoba ibhethri ye-lithium-ion ishajiwe, kufanele ikhishwe.Ngokombono, inqubo yokukhipha amabhethri e-lithium-ion ilinganiselwe.Lapho ukhipha, kufanele kuqashelwe ijubane nokujula kokukhishwa.Ukujula kokukhishwa yisilinganiso senani elikhishiwe kumthamo omncane, okuyisilinganiso senani elikhishiwe kumthamo wesitoreji esiphelele (umthamo omncane).Lapho inombolo iphansi, ukugeleza kuyancipha.Ukujula kokukhishwa kwebhethri ye-lithium-ion kuhlobene eduze ne-voltage kanye namanje, futhi kungavezwa ngokuya nge-voltage futhi kuvezwe ngokwamanje.

Ukujula kokukhishwa kwamabhethri e-lithium-ion kungu-80%, okusho ukuthi akhishwa ku-20% esele yomthamo wawo.

Ukujula kokukhishwa kuthinta ibhethri ngale ndlela elandelayo: ukujula kokukhishwa, kulula futhi kufushane impilo yebhethri ye-lithium-ion;esinye isici ukusebenza ku-flow curve.Ukujula kokukhishwa, i-voltage ne-current ingazinzile.Ngesikhathi esifanayo sokukhipha, i-value ye-voltage ephansi, ijula ​​ukujula kokukhishwa.Amanzi amancane aphuma ngokuphelele.Lapho i-current iphansi, isikhathi sokusebenza siba side futhi ishaja iyancipha ku-voltage efanayo.Kafushane, noma yisiphi isihloko ekukhishweni kwamabhethri e-lithium-ion kufanele sicabangele uhlelo lokukhipha futhi, ngokubaluleke kakhulu, lwamanje.

I-voltage yamabhethri e-lithium-ion yehla kancane njengoba ibhethri liphuma.

Isibonelo, uma ibhethri likhishwa ukuze ligcine u-80% womthamo walo, kodwa ibhethri lalishajwe ngokugcwele ku-4.2V, manje selilinganiswa ku-4.1V (nasi isibonelo sesilinganiso sokubhekisela kuphela, amanani azohluka amabhethri ekhwalithi ehlukene nokusebenza).

Uma ibhethri ye-lithium-ion ithatha amandla kunoma yisiphi isisetshenziswa, ukumelana kwangaphakathi kwebhethri kuyanyuka njengoba umthamo webhethri uncipha.

Lapho ukujula kokukhishwa kukhulu, ukumelana kuyanda futhi okwamanje kuhlala njalo, okudinga amandla engeziwe ebhethri futhi kuyichithe ngendlela yokushisa.

Ijika elizinzile lokukhipha amabhethri e-lithium-ion lingashintsha kakhulu uma ukujula kokukhipha kukhulu.

Ngakho-ke, ukukhawulela ukujula kokukhishwa kububanzi obuyisicaba kuzovumela amakhasimende ukuthi abe nokulawula okungcono kwamandla kanye nolwazi olungcono ezinhlelweni zabo zokusebenza.

Okufanele ukubheke ekukhipheni aibhethri ye-lithium-ion.Ukushaja ibhethri le-lithium-ion empeleni kumayelana nokuhlonza izici ezithinta ukukhishwa kwebhethri ye-lithium-ion.Okubalulekile wukwenza imisebenzi efanele lapho ushajwa, okuzophinde kube nomthelela ebhethrini elihlala isikhathi eside.

Ukujula kokukhishwa kwe-lithium ion, kukhulu ukulahleka kwebhethri.Uma ibhethri ye-Li-Ion ishajwe ngokugcwele, kukhulu ukulahleka kwebhethri.Amabhethri e-Li-ion kufanele abe sesimweni sokushajwa esimaphakathi, lapho ukuphila kwebhethri kuyinde kakhulu.
