Dukkanin tsarin yin cajin fakitin baturi lithium

Ana iya raba tsarin caji na batir Li-ion zuwa matakai huɗu: cajin dabara (ƙananan wutar lantarki kafin caji), cajin yau da kullun, cajin wutar lantarki akai-akai, da ƙare caji.

Mataki na 1: Ana amfani da cajin Trickle ChargeTrickle don fara cajin cikakken tantanin baturi da farko. Ana amfani da cajin Trickle lokacin da fakitin batirin Li-ion ya kasance ƙasa da kusan 3V. The trickle cajin halin yanzu shi ne daya bisa goma na akai halin yanzu cajin halin yanzu, watau 0.1c.

Mataki na 2: Cajin na yau da kullun Lokacin da ƙarfin baturi na lithium-ion ya tashi sama da madaidaicin cajin cajin, ana ƙara cajin halin yanzu don caji na yau da kullun. Matsakaicin caji na yanzu yana tsakanin 0.2C da 1.0C. Wutar batirin lithium-ion yana tashi a hankali tare da tsarin caji na yau da kullun, wanda gabaɗaya ana saita shi a 3.0-4.2V don baturi ɗaya.

Mataki na 3: Cajin wutar lantarki na dindindin Lokacin da fakitin baturi na Li-ion ƙarfin lantarki ya tashi zuwa 4.2V, yawan cajin na yau da kullun yana ƙare kuma matakin cajin wutar lantarki akai-akai yana farawa. A halin yanzu bisa ga matakin jikewa na tantanin halitta, yayin da tsarin caji ke ci gaba da cajin halin yanzu a hankali yana raguwa daga matsakaicin ƙimar, lokacin da aka rage zuwa 0.01C, ana ɗaukar cajin an ƙare.

Mataki na 4: Ƙarshen caji Akwai hanyoyi guda biyu na ƙarshe na caji: ta yin amfani da mafi ƙarancin hukunci na halin yanzu ko amfani da mai ƙidayar lokaci. Mafi ƙanƙantar hanyar yanzu tana lura da cajin halin yanzu daga matakin cajin wutar lantarki akai-akai kuma yana ƙare caji lokacin da cajin halin yanzu ya ragu zuwa kewayon 0.02C zuwa 0.07C. Hanya na biyu sau da aiwatar da caji daga farkon lokacin cajin wutar lantarki akai-akai kuma yana ƙare shi bayan sa’o’i biyu na ci gaba da caji.

Kamara mai hana ruwa ruwa tare da baturi mai caji, Dukkanin tsarin cajin baturin lithium, m baturi lithium, lifepak express defibrillator baturi, lithium polymer baturi ikon banki, Dukkanin tsarin cajin baturin lithium, duba baturin madannai mara waya, lissafin fakitin baturin lithium, cajar baturin jirgin ruwa, Dukkanin tsarin cajin baturin lithium, madadin baturi na na’ura mai ba da hanya tsakanin hanyoyin sadarwa, farashin baturin ajiyar makamashi.
