Libetri tsa lithium-ion li ratoa ka lebaka la matla a tsona a phahameng a matla, bophelo ba nako e telele, le sekhahla se tlase sa ho itšehla thajana. Ho bohlokoa ho utloisisa hore na libeteri tsena li sebetsa joang.
Likarolo tsa motheo tsa betri ea lithium-ion li kenyelletsa anode, cathode, electrolyte le separator. Lintho tsena li sebetsa 'moho ho boloka le ho lokolla matla hantle. Anode hangata e entsoe ka graphite, ha cathode e na le lithium metal oxide. Electrolyte ke tharollo ea letsoai ea lithium ka har'a motsoako oa lintho tse phelang, 'me karohano ke lera le lesesaane le thibelang lipotoloho tse khutšoane ka ho boloka anode le cathode li arohane.
Ts'ebetso ena e rarahaneng ea ho tjhaja e bohlokoa bophelong ba betri. Sistimi ea ho lekola betri ea DFUN e latela ts'ebetso ena ka nepo, e beha leihlo le ho rekota tefiso e felletseng le boemo ba ho lahla ho netefatsa hore tefiso e ngoe le e ngoe e bolokehile ebile e sebetsa hantle.
Ts'ebetso ea ho qosa le ho ntša betri ea lithium-ion ke ea bohlokoa ts'ebetsong ea bona. Ts'ebetso tsena li kenyelletsa ho sisinyeha ha lithium ion lipakeng tsa anode le cathode ka electrolyte.
Ha betri ea lithium-ion e tjhaja, li-ion tsa lithium li tloha ka har'a cathode ho ea ho anode. Ts'ebetso ena e etsahala hobane mohloli oa matla oa motlakase o kantle, o sebelisa motlakase ho pholletsa le liteishene tsa betri. Matla ana a tsamaisa li-ion tsa lithium ka electrolyte le ho kena ho anode, moo li bolokiloeng teng. Ts'ebetso ea ho tjhaja e ka aroloa ka mekhahlelo e 'meli e meholo: mohato oa kamehla oa hona joale (CC) le mohato oa kamehla oa voltage (CV).
Mokhahlelo oa Constant Current (CC) - Charger e sebelisa motlakase o tsitsitseng. Voltage e nyoloha butle-butle.
Voltage Threshold e fihlile - Ha motlakase o otla ~ 4.2V ka sele, tjhaja e fetola mokhoa.
Mokhahlelo oa Constant Voltage (CV) - Voltage e lula e ts'oaroe; hona joale tapers fatše.
Ho felisoa - Ho tjhaja ho emisa ha hona joale ho theoha ho ea ho e fokolang (hangata 3-5% ea hona joale ea pele).
Ho ntša betri ea lithium-ion ho kenyelletsa ts'ebetso e ka morao, moo li-ion tsa lithium li tlohang ho anode ho khutlela ho cathode. Ha betri e hoketsoe sesebelisoa, sesebelisoa se hula matla a motlakase ho tsoa betring. Sena se etsa hore li-ion tsa lithium li tlohe ho anode ebe li tsamaea ka electrolyte ho ea ho cathode, ho hlahisa motlakase o matlafatsang sesebelisoa.
Mojaro o Hoketsoe - Lielektrone li phalla ho tloha ho anode ho ea ho cathode ka potoloho ea kantle.
Lithium Ions Move - Li-ion li tsamaea ho tloha anode ho ea ho cathode ka electrolyte.
Voltage Declines - Matla a sele a fokotseha butle-butle ho tloha ~ 4.2V ho ea ho cutoff (~ 2.5-3.0V).
Discharge Termination - Sistimi ea taolo ea betri (BMS) e ea khaoha ho thibela ho tsoa ho feta tekano.
Lits'ebetso tsena li totobatsa phetiso ea li-ion tsa lithium le phallo e tsamaellanang ea lielektrone, tse bohlokoa ts'ebetsong ea betri.
Libetri tsa lithium-ion li tsebahala ka litšoaneleho tsa tsona tse ikhethileng, joalo ka matla a phahameng a matla, ho itšehla thajana, le bophelo ba nako e telele. Litšobotsi tsena li li etsa hore li tšoanelehe bakeng sa lits'ebetso moo matla a tšoarellang nako e telele a leng bohlokoa. Ho sebelisoa metrics e mengata ea bohlokoa ho lekola libeteri tsa lithium-ion:
Matla a Matla: E lekanya boholo ba matla a bolokiloeng molumong kapa boima bo fanoeng.
Cycle Life: E bonts'a palo ea li-cycle-charge-charge eo betri e ka e sebelisang pele matla a eona a theoha haholo.
C-rate: E hlalosa lebelo leo betri e tjhajwang ka lona kapa e tjhajwang ka lona ho ipapisitse le boholo ba yona.
Bophelo ba potoloho ea betri ha se boleng bo tsitsitseng; taolo ea ho ntša tefiso nakong ea ts'ebeliso ea 'nete e e ama haholo. Ka tlhahlobo ea nako ea 'nete le tlhahlobo ea data, the DFUN BMS Cloud Platform e u thusa ho lelefatsa bophelo ba ts'ebeletso ea pakete ea hau ea betri.
Ho beha leihlo nako ea ho tjhaja le ho ntsha dibetri tsa lithium-ion ho bohlokwa bakeng sa ho netefatsa bophelo ba bona bo bolelele le polokeho. Ho tjhaja ho feta tekano kapa ho tebela haholo ho ka baka tshenyo ya betri, ho fokotswa matla, esita le dikotsi tsa polokeho tse kang ho baleha ha mocheso. Ho netefatsa ts'ebetso e bolokehileng ea nako e telele ea lithium battery packs, tlhahlobo ea litsebi e bohlokoa. Fumana mokhoa oa ho DFUN Battery Monitoring System e fana ka tšireletso ea 24/7 bakeng sa lipakete tsa hau tsa betri.
DFUN e fana ka litharollo tsa profeshenale tsa ho lekola betri (BMS) tse nolofalletsang taolo e nepahetseng ea lits'ebetso tsa ho tjhaja le ho lahla — ka ho lekola liparamente tsa bohlokoa ka nako ea nnete joalo ka motlakase, hona joale le ho hanyetsa ka hare — ka tsela eo e fana ka litemoso tsa kotsi le ho lelefatsa bophelo ba betri.
