Ana amfani da baturan Lithium sosai a cikin na'urori kamar wayoyin salula, motocin lantarki, da tsarin makamashin hasken wuta. Koyaya, cajin su ba daidai ba na iya haifar da haɗarin aminci ko lalata na dindindin.
WHy ta amfani da cajin mai lantarki mafi girma yana da haɗari kumaYadda tsarin sarrafa baturi (BMS) yana kare baturan lithium?
Hadarin ya cika
Batunan Lithium suna da iyakokin ƙarfin lantarki. Misali:
.ASaurayi4(Lithium baƙin ƙarfe phosphate) tantanin halitta yana da kashin baya na3.2vkuma ya kamataKarka wuce 3.65vLokacin da aka caji
.ALi-ion(Lith Cobalt) Sel, gama gari a cikin wayoyi, yana aiki a3.7vkuma dole ne ya kasance a ƙasa4.2v
Yin amfani da caja tare da mafi girman ƙarfin lantarki fiye da iyakokin baturin batirin ya wuce kima mai yawa a cikin sel. Wannan na iya haifaroverheating,ƙaruwa, ko maThermal Runaway-A hatsari sarkar da aka dauki inda batirin ya kama wuta ko fashewa
Ta yaya BMS ke ceton rana
Tsarin gudanarwa na batir (BMS) yana aiki kamar "mai tsaro" don lithium baturan. Ga yadda yake aiki:
1.Sarrafawa
BMS masu sa ido kan kowane ƙwayoyin tantanin halitta. Idan an haɗa cajin mai lantarki mai ƙarfi, BMS ya gano yawan overvoltage daKashe da'awar cajiDon hana lalacewa
2.Tsarin zafin jiki
Caji na sauri ko ɗaukar nauyi yana haifar da zafi. A BMS Waƙoƙi zazzabi da rage ɗaukar hoto ko dakatar da caji idan baturin ya yi zafi sosai113.
3.Banada
A cikin batirin da yawa (kamar 12V ko 24V fakitoci), wasu sel suna cajin da sauri fiye da wasu. BMS ta sake sabunta makamashi don tabbatar da duk sel ya kai irin ƙarfin lantarki ɗaya, yana hana overcharging a sel mai ƙarfi
4.Ra'ayin Tsaro
Idan BMS ya gano matsaloli masu mahimmanci kamar matsanancin zafi ko ƙwayoyin cuta, ta cire baturin gaba ɗaya ta amfani da kayan haɗinMosufets(Sauti na lantarki) kohulɗa(na'urar relays)
Hanya madaidaiciya don cajin baturan Lithium
Koyaushe yi amfani da caja koyaushedace da ƙarfin fasahar ka da ilmin sunadarai.
Misali:
Baturi na 12V na ranar (4 sel a cikin jerin) yana buƙatar caja tare da14.6v matsakaicin fitarwa(4 × 3.65v)
Kunshin 7.4v lip (sel 2) na bukatar8.4v caja
Ko da BMS yake gabatarwa, ta amfani da cajin rashin jituwa ya jaddada tsarin. Yayinda BMS zai iya shiga tsakani, maimaitawa watsawa na iya raunana kayan aikinta a kan lokaci
Ƙarshe
Batura na Lithium suna da ƙarfi amma m. Ababban-inganci BMSyana da mahimmanci don tabbatar aminci, inganci, da tsawonsa. Yayinda zai iya kare tsoratarwa na ɗan lokaci-lokaci game da cajin mai lantarki, dogaro da wannan yana da haɗari. Koyaushe yi amfani da madaidaicin cajar - batir ɗinka (da aminci) zai gode.
Ka tuna: BMS yana kama da wurin zama. Yana can don ceton ku a cikin gaggawa, amma kada ku gwada iyakokinsa!
