Gabatarwa:
Batirin lithium suna ko'ina a rayuwarmu. Batirin wayar mu da batirin mota masu lantarki duk sun kasancebatirin lithium, amma kun san wasu mahimman kalmomin baturi, nau'ikan baturi, da matsayi da bambancin jerin baturi da haɗin haɗin kai? Bari mu bincika ilimin batura tare da Heltec.
Kalmomin asali na baturan lithium
1) C-rauni
Yana nufin rabon halin yanzu zuwa ƙarfin ƙididdiga na baturin lithium yayin caji da fitarwa. Ya bayyana yadda sauri da sauri za a iya caja da fitar da baturin. Adadin caji da fitarwa ba dole ba ne iri ɗaya. Misali:
1C: Cikakken fitar da baturi a cikin awa 1 (cikakken caji)
0.2C: cikakken fitar da baturin cikin sa'o'i 5 (cikakken caji)
5C: Cikakken fitar da baturi a cikin awanni 0.2 (cikakken caji)
2) iyawa
Adadin wutar lantarki da aka adana a cikinbaturi lithium. Naúrar ita ce mAh ko Ah.
Haɗe da ƙimar, alal misali, idan baturin yana 4800mAh kuma ƙimar cajin shine 0.2C, yana nufin cewa yana ɗaukar awa 5 don cajin baturin gaba ɗaya daga fanko (yin watsi da matakin farko na caji lokacin da baturin yayi ƙasa sosai).
Cajin halin yanzu shine: 4800mA*0.2C=0.96A
3) Tsarin sarrafa batirin BMS
Tsarin yana sarrafawa da sarrafa caji / cajin baturin, gano zafin jiki da ƙarfin baturi, haɗi tare da tsarin mai watsa shiri, daidaita ƙarfin baturi, da sarrafa aikin aminci na fakitin baturi na lithium.
4) Zagayowar
Tsarin cajin baturi da fitarwa ana kiransa zagaye. Idan baturin yana amfani da kashi 80 cikin 100 na yawan kuzarinsa a kowane lokaci, rayuwar zagayowar batirin lithium-ion zai iya kaiwa sau dubbai.
Nau'in Batirin Lithium
A halin yanzu, ƙwayoyin lithium-ion na kasuwanci sun fi cylindrical, murabba'i da fakiti mai laushi.
Kwayoyin cylindrical 18650 sune ƙwayoyin lithium-ion tare da mafi girman ƙarar samarwa a halin yanzu. Tsarin mu na G na duba sel batir iri ne.
Silsilar salula da haɗin layi ɗaya
Tantanin halitta shine ainihin abin da ke cikinbaturi lithium. Adadin sel ya bambanta dangane da aikace-aikacen baturi, amma duk batura suna buƙatar haɗa su ta hanyoyi daban-daban don cimma ƙarfin lantarki da ƙarfin da ake buƙata.
Lura: Sharuɗɗan haɗin layi ɗaya suna da tsauri. Don haka, haɗin layi ɗaya na farko sannan kuma haɗin layi na iya rage buƙatun daidaiton baturi.
Tambaya: Menene bambanci tsakanin batura-jeri uku da guda huɗu masu daidaitawa da batura masu layi ɗaya da uku?
A: Wutar lantarki da iya aiki sun bambanta.Haɗin jeri yana ƙara ƙarfin lantarki, kuma haɗin layi ɗaya yana ƙara ƙarfin halin yanzu (ƙarfin)
1) Haɗin layi ɗaya
A ɗauka cewa ƙarfin lantarki na tantanin baturi shine 3.7V kuma ƙarfin shine 2.4Ah. Bayan layi daya dangane, da m ƙarfin lantarki na tsarin ne har yanzu 3.7V, amma iya aiki yana ƙaruwa zuwa 7.2Ah.
2) Jerin haɗin gwiwa
A ɗauka cewa ƙarfin lantarki na tantanin baturi shine 3.7V kuma ƙarfin shine 2.4Ah. Bayan jerin haɗawa, m ƙarfin lantarki na tsarin ne 11.1V, da kuma iya aiki ya kasance ba canzawa.
Idan tantanin baturi jerin uku ne da guda biyu a layi daya, jimlar sel 6 18650, to baturin shine 11.1V da 4.8Ah. Tesla Model-S sedan yana amfani da ƙwayoyin Panasonic 18650, kuma fakitin baturi 85kWh yana buƙatar kusan sel 7,000.
Kammalawa
Heltec zai ci gaba da sabunta sanannun ilimin kimiyya game dabatirin lithium. Idan kuna sha'awar, za ku iya kula da shi. A lokaci guda, muna samar muku da fakitin batirin lithium masu inganci don siye da samar da ayyuka na musamman don biyan bukatunku.
Heltec Energy shine amintaccen abokin tarayya a masana'antar fakitin baturi. Tare da mu mai da hankali kan bincike da haɓakawa, tare da cikakken kewayon kayan aikin baturi, muna ba da mafita guda ɗaya don saduwa da buƙatun ci gaba na masana'antu. Alƙawarinmu na ƙwaƙƙwara, ingantaccen mafita, da ƙaƙƙarfan haɗin gwiwar abokin ciniki sun sanya mu zaɓi don masana'antun fakitin baturi da masu siyarwa a duk duniya.
Idan kuna da wasu tambayoyi ko kuna son ƙarin koyo, da fatan za ku yi jinkirikai gare mu.
