Libetri tsa lithium li hohle maphelong a rona. Libetri tsa rona tsa lifono tsa selefouno le libeteri tsa likoloi tsa motlakase kaofela li tenglibeteri tsa lithium, empa na o tseba mantsoe a motheo a betri, mefuta ea betri, le karolo le phapang ea letoto la betri le khokahano e bapileng? A re hlahlobeng tsebo ea libeteri ka Heltec.
Mantsoe a motheo a libeteri tsa lithium
1) Sekhahla sa C
E bua ka karolelano ea motlakase le bokhoni bo tloaelehileng ba betri ea lithium nakong ea ho tjhaja le ho ntša motlakase. E hlalosa hore na betri e ka tjhaja le ho ntša motlakase ka lebelo le lekae. Sekhahla sa ho tjhaja le ho ntša motlakase ha se hlile ha se tšoane. Mohlala:
1C: ntsha betri ka botlalo nakong ea hora e le 'ngoe (tjhaja e felletseng)
0.2C: ntsha betri ka botlalo nakong ea lihora tse 5 (tjhaja e felletseng)
5C: ntsha betri ka botlalo nakong ea lihora tse 0.2 (tjhaja e felletseng)
2) Bokgoni
Bongata ba motlakase o bolokiloeng hobetri ea lithiumYuniti ke mAh kapa Ah.
Ha e kopantswe le sekgahla, mohlala, haeba betri e le 4800mAh mme sekgahla sa ho tjhaja e le 0.2C, ho bolela hore ho nka dihora tse 5 hore betri e tjhajwe ka botlalo ho tloha e se na letho (ho hlokomolohuwa mohato wa pele ho tjhaja ha betri e le tlase haholo).
Nako ea ho tjhaja ke: 4800mA*0.2C=0.96A
3) Sistimi ea taolo ea betri ea BMS
Sistimi e laola le ho laola ho tjhaja/ho ntsha betri, e lemoha mocheso le motlakase wa betri, e hokahana le sistimi ya moamoheli, e leka-lekanya motlakase wa betri, mme e laola tshebetso ya polokeho ya pakete ya betri ya lithium.
4) Potoloho
Mokhoa oa ho tjhaja le ho ntša betri o bitsoa potoloho. Haeba betri e sebelisa 80% feela ea matla a eona kaofela nako le nako, bophelo ba potoloho ea libeteri tsa lithium-ion bo ka ba holimo ho fihlela makhetlo a likete.
Mofuta oa Betri ea Lithium
Hona jwale, disele tsa lithium-ion tsa kgwebo haholoholo di na le sebopeho sa cylindrical, sekwere le bonolo.
Lisele tse 18650 tse silindara ke lisele tsa lithium-ion tse nang le bophahamo bo phahameng ka ho fetisisa ba tlhahiso hajoale. Lisele tsa rona tsa betri tsa monitor tsa letoto la G ke tsa mofuta ona.
Letoto la sele le khokahano e bapileng
Sele ke karolo ea bohlokoa eabetri ea lithiumPalo ea lisele e fapana ho latela ts'ebeliso ea betri, empa libeteri tsohle li hloka ho hokeloa ka litsela tse fapaneng ho fihlela motlakase le matla a hlokahalang.
Hlokomela: Maemo a khokahano e bapileng a boima haholo. Ka hona, khokahano e bapileng pele ebe khokahano e bapileng e ka fokotsa ditlhoko tsa botsitso ba betri.
P: Phapang ke efe pakeng tsa libeteri tsa letoto la boraro le tse 'ne tse tšoanang le tse 'ne tse tšoanang le tse tharo tse fapaneng?
K: Motlakase le bokgoni di fapane.Khokahano ea letoto e eketsa motlakase, 'me khokahano e tsamaeang ka nako e le' ngoe e eketsa hona joale (bokhoni)
1) Khokahano e tsamaellanang
Nka hore motlakase oa sele ea betri ke 3.7V 'me matla ke 2.4Ah. Kamora khokahano e tsamaellanang, motlakase oa terminal oa sistimi o ntse o le 3.7V, empa matla a eketseha ho fihlela ho 7.2Ah.
2) Khokahano ea letoto
Nka hore motlakase oa sele ea betri ke 3.7V 'me matla ke 2.4Ah. Kamora khokahano ea letoto, motlakase oa terminal oa sistimi ke 11.1V, 'me matla a lula a sa fetohe.
Haeba sele ea betri e le letoto la tse tharo le tse peli tse bapileng, e leng lisele tse 6 18650 kaofela, joale betri ke 11.1V le 4.8Ah. Sedan ea Tesla Model-S e sebelisa lisele tsa Panasonic 18650, 'me pakete ea betri ea 85kWh e hloka lisele tse ka bang 7,000.
Qetello
Heltec e tla tswela pele ho ntlafatsa tsebo e tsebahalang ya saense mabapi lelibeteri tsa lithiumHaeba o na le thahasello, o ka e ela hloko. Ka nako e ts'oanang, re o fa dipakete tsa betri tsa lithium tsa boleng bo hodimo tseo o ka di rekang le ho fana ka ditshebeletso tse ikgethileng ho fihlela ditlhoko tsa hao.
Heltec Energy ke molekane oa hau ea tšepahalang tlhahisong ea liphutheloana tsa betri. Ka ho tsepamisa maikutlo ha rona ho sa feleng lipatlisisong le nts'etsopele, hammoho le mefuta e mengata ea lisebelisoa tsa betri, re fana ka litharollo tsa sebaka se le seng ho fihlela litlhoko tse ntseng li fetoha tsa indasteri. Boitlamo ba rona ba bokhabane, litharollo tse etselitsoeng uena, le likamano tse matla tsa bareki li re etsa khetho e ntle bakeng sa bahlahisi le bafepedi ba liphutheloana tsa betri lefatšeng ka bophara.
Haeba o na le lipotso kapa o ka rata ho tseba ho eketsehileng, ka kopo o se ke oa tsilatsila hoikopanye le rona.
