Gabatarwa:
Batirin lithium yana ko'ina a rayuwarmu. Batirin wayoyin hannu da batirin motar lantarki duk suna nanbatirin lithium, amma shin kun san wasu sharuɗɗan batirin asali, nau'ikan batirin, da kuma rawar da bambancin jerin batirin da haɗin layi ɗaya? Bari mu bincika ilimin batirin tare da Heltec.
Kalmomin asali na batirin lithium
1) C-rate
Yana nufin rabon wutar lantarki da ƙarfin batirin lithium na ɗan lokaci yayin caji da fitarwa. Yana bayyana yadda za a iya caji da kuma fitar da batirin cikin sauri. Yawan caji da fitarwa ba lallai bane iri ɗaya ne. Misali:
1C: Cire batirin gaba ɗaya cikin awa 1 (cikakken caji)
0.2C: Cire batirin gaba ɗaya cikin awanni 5 (cikakken caji)
5C: Cire batirin gaba ɗaya cikin awanni 0.2 (cikakken caji)
2) Ƙarfin aiki
Adadin wutar lantarki da aka adana a cikinbatirin lithiumNaúrar ita ce mAh ko Ah.
Idan aka haɗa da ƙimar, misali, idan batirin 4800mAh ne kuma ƙimar caji shine 0.2C, yana nufin yana ɗaukar awanni 5 kafin batirin ya cika caji daga babu komai (yin watsi da matakin caji kafin lokacin caji lokacin da batirin yayi ƙasa sosai).
Wutar caji ita ce: 4800mA*0.2C=0.96A
3) Tsarin sarrafa batirin BMS
Tsarin yana sarrafawa da kuma sarrafa caji/fitar da batirin, yana gano zafin jiki da ƙarfin batirin, yana haɗawa da tsarin mai masaukin baki, yana daidaita ƙarfin batirin, kuma yana kula da aikin aminci na fakitin batirin lithium.
4) Zagaye
Ana kiran tsarin caji da fitar da batirin a zagaye. Idan batirin yana amfani da kashi 80% na jimlar kuzarinsa a kowane lokaci, tsawon lokacin zagayowar batirin lithium-ion zai iya kaiwa har sau dubbai.
Nau'in Batirin Lithium
A halin yanzu, ƙwayoyin lithium-ion na kasuwanci galibi silinda ne, murabba'i kuma mai laushi.
Kwayoyin silinda na 18650 sune ƙwayoyin lithium-ion waɗanda ke da mafi girman adadin samarwa a halin yanzu. Kwayoyin batirin mu na jerin G suna da irin wannan nau'in.
Jerin tantanin halitta da haɗin layi ɗaya
Tantanin halitta shine babban ɓangarenbatirin lithiumAdadin ƙwayoyin halitta ya bambanta dangane da amfani da batirin, amma duk batura suna buƙatar a haɗa su ta hanyoyi daban-daban don cimma ƙarfin lantarki da wutar lantarki da ake buƙata.
Lura: Sharuɗɗan haɗin layi ɗaya suna da tsauri sosai. Saboda haka, haɗin layi ɗaya da farko sannan haɗin layi zai iya rage buƙatun daidaiton baturi.
T: Menene bambanci tsakanin batirin jeri uku da na jeri huɗu da na jeri huɗu da na jeri uku?
A: Ƙarfin wutar lantarki da ƙarfinsa sun bambanta.Haɗin jeri yana ƙara ƙarfin lantarki, kuma haɗin layi ɗaya yana ƙara ƙarfin lantarki (ƙarfin aiki)
1) Haɗin layi ɗaya
A ɗauka cewa ƙarfin batirin shine 3.7V kuma ƙarfin shine 2.4Ah. Bayan haɗin layi ɗaya, ƙarfin ƙarshe na tsarin har yanzu yana 3.7V, amma ƙarfin yana ƙaruwa zuwa 7.2Ah.
2) Haɗin jeri
A ɗauka cewa ƙarfin batirin shine 3.7V kuma ƙarfin shine 2.4Ah. Bayan haɗa jerin, ƙarfin ƙarshe na tsarin shine 11.1V, kuma ƙarfin ba zai canza ba.
Idan batirin yana da jeri uku da biyu a layi ɗaya, jimillar ƙwayoyin halitta 6 18650, to batirin yana da 11.1V da 4.8Ah. Sedan na Tesla Model-S yana amfani da ƙwayoyin Panasonic 18650, kuma fakitin batirin 85kWh yana buƙatar kimanin ƙwayoyin halitta 7,000.
