Libetri tsa lithium li sebelisoa haholo lisebelisoa tse kang li-smartphone, likoloi tsa motlakase le lisebelisoa tsa matla a letsatsi. Leha ho le joalo, ho li lefisa ka phoso ho ka lebisa likotsing tsa polokeho kapa tšenyo e sa feleng.
Why ho sebelisa tjhaja ea matla a holimo ho kotsi lekamoo Battery Management System (BMS) e sireletsang libeteri tsa lithium?
Kotsi ea ho Lefisa Ho Feta
Libetri tsa lithium li na le meeli e thata ea motlakase. Ka mohlala:
.ALiFePO4(Lithium Iron Phosphate) sele e na le motlakase oa lebitso la3.2Vle lokelaha ho mohla e fetang 3.65Vha e qositsoe ka botlalo
.ALi-ion(Lithium Cobalt) sele, e tloaelehileng ka lifono, e sebetsa ho3.7V'me e tlameha ho lula ka tlase4.2V
Ho sebelisa tjhaja e nang le motlakase o mongata ho feta tekanyo ea betri ho qobella matla a mangata ho kena liseleng. Sena se ka bakaho chesa haholo,ho ruruha, kapa esita leho baleha ka mocheso- ketane e kotsi ea ketane moo betri e ka chesang kapa e phatlohang
Kamoo BMS e Bolokang Letsatsi
A Battery Management System (BMS) e sebetsa joalo ka "mohlokomeli" oa libeteri tsa lithium. Mona ke kamoo e sebetsang kateng:
1.Taolo ea Motlakase
BMS e hlokomela motlakase oa sele ka 'ngoe. Haeba tjhaja e nang le matla a phahameng e hoketswe, BMS e bona ho feta matla lee khaola potoloho ea ho tjhajaho thibela tshenyo
2.Molao oa Mocheso
Ho tjhaja kapele kapa ho tjhaja haholo ho baka mocheso. BMS e latela mocheso mme e fokotsa lebelo la ho tjhaja kapa e emisa ho tjhaja ha betri e futhumala haholo113.
3.Ho leka-lekanya lisele
Ka libeteri tse nang le lisele tse ngata (joaloka lipakete tsa 12V kapa 24V), lisele tse ling li tjhaja kapele ho feta tse ling. BMS e fana ka matla bocha ho etsa bonnete ba hore lisele tsohle li fihla matla a tšoanang, ho thibela ho chaja ho feta liseleng tse matla
4.Tshireletso Shutdown
Haeba BMS e lemoha mathata a bohlokoa joalo ka mocheso o feteletseng kapa li-voltage spikes, e hakolla betri ka botlalo e sebelisa likarolo tse kang.MOSFETs(li-switches tsa elektroniki) kapalikhokahanyo(li-relay tsa mochini)
Mokhoa o nepahetseng oa ho tjhaja libetri tsa lithium
Sebelisa tjhaja kamehlaho tsamaisana le matla a betri ea hau le k'hemistri.
Ka mohlala:
Betri ea 12V LiFePO4 (lisele tse 4 ka lihlopha) e hloka tjhaja e nang le14.6V boholo ba tlhahiso(4 × 3.65V)
Pakete ea Li-ion ea 7.4V (lisele tse 2) e hloka8.4V tjhaja
Leha BMS e le teng, ho sebelisa tjhaja e sa tsamaellaneng ho hatella sistimi. Le hoja BMS e ka kenella, ho pepeseha ha overvoltage khafetsa ho ka fokolisa likarolo tsa eona ha nako e ntse e ea
Qetello
Libetri tsa lithium li matla empa lia tiea. ABMS ea boleng bo holimoho bohlokoa ho netefatsa polokeho, ts'ebetso e sebetsang, le bophelo bo bolelele. Le hoja e ka sireletsa ka nakoana khahlanong le tjhaja e nang le matla a holimo, ho itšetleha ka sena ho kotsi. Kamehla sebelisa tjhaja e nepahetseng—betri ya hao (le polokeho) di tla o leboha!
Hopola: BMS e tšoana le lebanta la pholoso. E teng ho u pholosa maemong a tšohanyetso, empa ha ua lokela ho leka meeli ea eona!
