Ndeipi kudzika kwekubuda kwe lithium-ion mabhatiri uye kuti ungainzwisisa sei?

Pane dzidziso mbiri pamusoro pekudzika kwekubuda kwelithium mabhatiri. Imwe inoreva kuti yakawanda sei voltage inodonha mushure mekunge bhatiri raburitswa kwenguva yakati rebei, kana kuti yakawanda sei iyo terminal voltage (panguva iyo inowanzoburitswa). Imwe yacho inoreva huwandu hwebhatiri, hunova huwandu hwechaji yakabviswa.

Lithium-ion bhatirikudzika kwekubuda, zvinhu zvinodzikamisa kudzika kwekubuda kwe lithium-ion mabhatiri.Sezvo iyo lithium-ion bhatiri yakachajwa, inofanirwa kuburitswa. Theoretically, iyo yekuburitsa mabhatiri e-lithium-ion yakaenzana. Paunenge uchiburitsa, kutarisisa kunofanirwa kubhadharwa kune kukurumidza uye kudzika kwekubuda. Iyo yakadzika yekubuda ndiyo chiyero chemari inoburitswa kune zita rezita, inova chiyero chemari inoburitswa kune yakazara yekuchengetedza simba (zita rezita). Iyo yakaderera nhamba, iyo isina kudzika kuyerera. Kudzika kwekubuda kwe lithium-ion bhatiri yakanyatsoenderana nemagetsi uye ikozvino, uye inogona kuratidzwa maererano nemagetsi uye inoratidzwa maererano nezvino.

Kudzika kwekubuda kwemabhatiri e-lithium-ion ndeye 80%, zvinoreva kuti inobudiswa kune yakasara 20% yehuwandu hwavo.

Kudzika kwekuyerera kunobata bhatiri sezvinotevera: iyo yakadzika kubuda, iyo iri nyore uye yakapfupika hupenyu hwe lithium-ion battery; chimwe chinhu ndechekuita pane inoyerera curve. Iyo yakadzika yekuyerera, iyo yakanyanya kusagadzikana iyo voltage uye ikozvino. Panguva imwechete yekuburitsa, iyo yakaderera kukosha kwevoltage, iyo yakadzika kudzika kwekubuda. Madiki emvura anobuda zvakanyanya. Iyo yakaderera ikozvino, iyo yakareba nguva yekumhanya uye kushoma kubhadharisa pamhepo imwechete. Mukupfupisa, chero musoro pamusoro pekubuda kwe lithium-ion mabhatiri inofanirwa kufunga nezve discharge system uye, crucially, ikozvino.

Iyo voltage yemabhatiri e-lithium-ion inodzikira zvishoma nezvishoma sezvo bhatiri richibuda.

Semuenzaniso, bhatiri parinobuditswa kuti richengetedze 80% yehuwandu hwaro, asi bhatiri rakange rakachajwa pa4.2V, rave kuyerwa pa 4.1V (heino muenzaniso wefungidziro yekutarisa chete, kukosha kuchasiyana mabhatiri emhando dzakasiyana uye kuita).

Kana bhatiri re lithium-ion richiisa simba kune chero mudziyo, kuramba kwemukati kwebhatiri kunowedzera sezvo simba rinodzikira.

Kana kudzika kwekubuda kwakanyanya, kushorwa kunowedzera uye ikozvino kunogara kuripo, izvo zvinoda simba rakawanda kubva kubhatiri uye kuriparadza nenzira yekupisa.

Iyo neimwe nzira yakagadzikana yekuburitsa curve yemabhatiri e-lithium-ion inogona kushanduka zvakanyanya kana kudzika kwekubuda kwakawanda.

Naizvozvo, kudzikisira kudzika kwekuburitsa kune yakati sandara renji kunobvumira vatengi kuve nekutonga kurinani kwesimba uye ruzivo rwuri nani mukushandisa kwavo.

Zvekutsvaga pakuburitsa alithium-ion bhatiri. Kuburitsa bhatiri re lithium-ion ndezvechokwadi kuona zvinhu zvinokanganisa kubuda kwebhatiri re lithium-ion. Chinhu chakakosha kuita mashandiro akakodzera paunenge uchiburitsa, izvo zvichabatsirawo kune bhatiri rinogara kwenguva refu.

Iyo yakadzika iyo lithium ion discharge, iyo yakakura kurasikirwa kwebhatiri. Iyo yakanyanya kuchaja bhatiri reLi-Ion, ndiko kukura kwekurasikirwa kwebhatiri.Mabhatiri eLi-ion anofanirwa kunge ari pakati pekuchaja, uko hupenyu hwebhatiri hwakareba.
