Libetri tsa lithium li hohle bophelong ba rona. Libetri tsa rona tsa mehala ea thekeng le libeteri tsa koloi tsa motlakase ke tsona kaofelalibeteri tsa lithium, empa na u tseba mantsoe a mang a mantlha a betri, mefuta ea betri, le karolo le phapang ea letoto la betri le khokahano e tšoanang? Ha re hlahlobeng tsebo ea libeteri ka Heltec.
Mantsoe a motheo a libeteri tsa lithium
1) Sekhahla sa C
E bolela karo-karolelano ea hona joale ho matla a mabitso a betri ea lithium nakong ea ho tjhaja le ho tjhaja. E hlalosa hore na betri e ka tjhajwa le ho tjhajwa kapele hakae. Litefiso tsa ho tjhaja le ho tjhaja ha di tshwane. Ka mohlala:
1C: ntša betri ka botlalo nakong ea hora e le 'ngoe (tefo e felletseng)
0.2C: ntša betri ka botlalo nakong ea lihora tse 5 (tefo e felletseng)
5C: Hlakola betri ka botlalo nakong ea lihora tse 0.2 (tefo e felletseng)
2) Bokhoni
Chelete ea motlakase e bolokiloeng ka har'alithium betri. Sesebelisoa ke mAh kapa Ah.
E kopantsoe le tekanyo, mohlala, haeba betri e le 4800mAh 'me tekanyo ea ho tjhaja ke 0.2C, ho bolela hore ho nka lihora tse 5 hore betri e qosoe ka ho feletseng ho tloha ho se nang letho (ho hlokomoloha sethaleng sa ho tjhaja pele 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 lahla betri, e lemoha mocheso le voltage ea betri, e hokahana le sistimi e amohelang, e leka-lekanya matla a betri, mme e laola ts'ebetso ea ts'ireletso ea pakete ea betri ea lithium.
4) Potoloho
Tshebetso ya ho tjhaja le ho tjhaja betri e bitswa cycle. 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 makhetlo a likete.
Mofuta oa betri ea lithium
Hona joale, lisele tsa khoebo tsa lithium-ion li na le li-cylindrical, square and soft-pack.
Lisele tsa cylindrical tsa 18650 ke lisele tsa lithium-ion tse nang le molumo o phahameng ka ho fetisisa oa tlhahiso hona joale. Lisele tsa rona tsa li-betri tsa G ke tsa mofuta ona.
Letoto la lisele le khokahano e bapileng
Sele ke karolo ea mantlha ealithium betri. Palo ea lisele e fapana ho latela ts'ebeliso ea betri, empa libeteri tsohle li hloka ho hokahana ka mekhoa e fapaneng ho fihlela matla le matla a hlokahalang.
Tlhokomeliso: Lipehelo tsa khokahano e tšoanang li boima haholo. Ka hona, khokahano e bapileng pele ebe khokahano ea letoto e ka fokotsa litlhoko tsa botsitso ba betri.
P: Phapano ke efe lipakeng tsa li-betri tsa li-tri-series le tse 'ne-parallel le tse 'ne tse bapileng le tse tharo?
A: Matla le matla li fapane.Khokahano ea Series e eketsa voltage, mme khokahano e tšoanang e eketsa hona joale (bokhoni)
1) Khokahano e tšoanang
Nka hore motlakase oa sele ea betri ke 3.7V mme matla ke 2.4Ah. Ka mor'a ho hokahanya ka tsela e ts'oanang, motlakase oa motlakase oa tsamaiso o ntse o le 3.7V, empa matla a eketseha ho 7.2Ah.
2) Letoto kgokelo
Nka hore motlakase oa sele ea betri ke 3.7V mme matla ke 2.4Ah. Ka mor'a ho hokahanya letoto, motlakase oa motlakase oa tsamaiso ke 11.1V, 'me matla a lula a sa fetohe.
Haeba sele ea betri e le lihlopha tse tharo le tse peli tse tšoanang, kakaretso ea lisele tsa 6 18650, joale betri ke 11.1V le 4.8Ah. Tesla Model-S sedan e sebelisa lisele tsa Panasonic 18650, 'me pakete ea betri ea 85kWh e hloka lisele tse ka bang 7,000.
Qetello
Heltec e tla tsoela pele ho nchafatsa tsebo e tsebahalang ea mahlale mabapi lelibeteri tsa lithium. Haeba u thahasella, u ka e ela hloko. Ka nako e ts'oanang, re u fa lipakete tsa betri tsa lithium tsa boleng bo holimo hore u li reke le ho fana ka lits'ebeletso tse ikhethileng ho fihlela litlhoko tsa hau.
Heltec Energy ke molekane oa hau eo u mo tšepang mosebetsing oa ho etsa li-betri pack. Ka ho tsepamisa maikutlo a rona a sa feleng lipatlisisong le nts'etsopele, hammoho le lisebelisoa tsa rona tse felletseng tsa lisebelisoa tsa betri, re fana ka tharollo ea sebaka se le seng ho fihlela litlhoko tse tsoelang pele tsa indasteri. Boitlamo ba rona ba bokhabane, litharollo tse lokiselitsoeng, le litšebelisano tse matla tsa bareki li re etsa khetho ea mantlha bakeng sa baetsi le barekisi ba lipakete tsa betri lefatšeng ka bophara.
Haeba u na le lipotso kapa u lakatsa ho tseba haholoanyane, ka kopo u se ke oa tsilatsilafihla ho rona.
