Libetri tsa Scooter ea Motlakase
Betri ke "tanka ea mafura" ea scooter ea hau ea motlakase.E boloka matla a sebelisoang ke enjene ea DC, mabone, molaoli le lisebelisoa tse ling.

Li-scooter tse ngata tsa motlakase li tla ba le mofuta o itseng oa lithium ion-based battery pack ka lebaka la matla a tsona a matla le bophelo bo bolelele.Li-scooter tse ngata tsa motlakase bakeng sa bana le mefuta e meng e theko e tlaase li na le libeteri tsa lead-acid.Ka har'a scooter, pakete ea betri e entsoe ka lisele tse ikemetseng le lisebelisoa tsa elektroniki tse bitsoang sistimi ea taolo ea betri e e bolokang e sebetsa ka polokeho.
Lipakete tse kholo tsa betri li na le bokhoni bo bongata, bo lekantsoeng ka lihora tsa watt, 'me li tla lumella scooter ea motlakase hore e tsamaee hole.Leha ho le joalo, li boetse li eketsa boholo le boima ba scooter - e etsa hore e se nkehe habonolo.Ho feta moo, libeteri ke e 'ngoe ea likarolo tse turang haholo tsa scooter mme litšenyehelo ka kakaretso lia eketseha ho latela.

Mefuta ea Libetri
Lipakete tsa betri tsa scooter li entsoe ka lisele tse ngata tsa betri ka bomong.Haholo-holo, li entsoe ka lisele tse 18650, sehlopha sa boholo ba libeteri tsa lithium ion (Li-Ion) tse nang le litekanyo tsa cylindrical tse 18 mm x 65 mm.

Sele e 'ngoe le e 'ngoe ea 18650 ka har'a beteri pakete ha e khahlise - e hlahisa matla a motlakase a ~ 3.6 volts (nominal) mme e na le matla a ka bang 2.6 amp hours (2.6 A·h) kapa hoo e ka bang 9.4 watt-horas (9.4 Wh).

Lisele tsa betri li sebetsa ho tloha ho 3.0 volts (0% tefiso) ho fihla ho 4.2 volts (tefiso ea 100%).

Lithium Ion
Li-betri tsa Li-Ion li na le matla a matla a matla, boholo ba matla a bolokiloeng ho latela boima ba 'mele.Li boetse li na le nako e telele ea bophelo bo botle ho bolelang hore li ka ntšoa le ho tjhajoa kapa ho "palangoa" ka makhetlo a mangata 'me li ntse li boloka matla a tsona a polokelo.

Li-ion ha e le hantle e bua ka lik'hemik'hale tse ngata tsa betri tse kenyelletsang lithium ion.Lenane le lekhutšoane le ka tlase ke lena:

Lithium manganese oxide (LiMn2O4);aka: IMR, LMO, Li-manganese
Nickel ea lithium manganese (LiNiMnCoO2);ka INR, NMC
Lithium nickel cobalt aluminium oxide (LiNiCoAlO2);aka NCA, Li-aluminium
Lithium nickel cobalt oxide (LiCoO2);ka NCO
Lithium cobalt oxide (LiCoO2);aka ICR, LCO, Li-cobalt
Lithium iron phosphate (LiFePO4);aka IFR, LFP, Li-phosphate
E 'ngoe le e' ngoe ea lik'hemik'hale tsena tsa betri e emela khoebo pakeng tsa polokeho, bophelo bo bolelele, bokhoni le tlhahiso ea hajoale.

Lithium Manganese (INR, NMC)
Ka lehlohonolo, li-scooter tse ngata tsa boleng ba motlakase li sebelisa k'hemistri ea betri ea INR - e 'ngoe ea lik'hemik'hale tse sireletsehileng ka ho fetisisa.Betri ena e fana ka bokhoni bo phahameng le tlhahiso ea hona joale.Ho ba teng ha manganese ho theola khanyetso ea kahare ea betri, ho lumella tlhahiso e phahameng ea hajoale ha e ntse e boloka mocheso o tlase.Ka lebaka leo, sena se fokotsa menyetla ea ho baleha mocheso le mollo.

Li-scooter tse ling tsa motlakase tse nang le k'hemistri ea INR li kenyelletsa mehlala ea WePed GT 50e le Dualtron.

Asiti ea lead
Lead-acid ke k'hemik'hale ea khale haholo ea betri e fumanehang hangata likoloing le likoloing tse ling tse kholo tsa motlakase, joalo ka likariki tsa kolofo.Li boetse li fumaneha ho li-scooters tse ling tsa motlakase;haholo-holo, li-scooters tsa bana tse theko e tlaase tse tsoang lik'hamphani tse kang Razor.

Libetri tsa loto li na le molemo oa ho ba theko e tlaase, empa li na le bothata ba ho ba le matla a fokolang haholo, ho bolelang hore li boima bo bongata ha li bapisoa le matla ao li a bolokang.Ha ho bapisoa, libeteri tsa Li-ion li na le matla a ka bang 10X ha a bapisoa le libeteri tsa lead-acid.

Lipakete tsa Battery
Ho aha pakete ea betri e nang le matla a li-watt tse makholo kapa tse likete, lisele tse ngata tsa 18650 Li-ion li bokelloa hammoho ho ba sebopeho se kang setene.Pakete ea betri e kang litene e hlahlojoa le ho laoloa ke potoloho ea elektronike e bitsoang "betri management system" (BMS), e laolang ho phalla ha motlakase ho kena le ho tsoa ka har'a betri.
Lisele tsa motho ka mong ka har'a betri pakete li hokahantsoe ka letoto (qetellong ho isa qetellong) tse akaretsang matla a tsona.Ke kamoo ho ka khonehang ho ba le li-scooters tse nang le 36 V, 48 V, 52 V, 60 V, kapa lipakete tse kholo tsa betri.

Lithapo tsena ka bomong (libetri tse ngata ka letoto) li hokahanngoa ka ho bapa ho eketsa tlhahiso ea hona joale.

Ka ho fetola palo ea lisele ka letoto le ka tsela e ts'oanang, baetsi ba li-scooter tsa motlakase ba ka eketsa matla a motlakase kapa max current le amp hour capacity.

Ho fetola tlhophiso ea betri ho ke ke ha eketsa kakaretso ea matla a bolokiloeng, empa ka nepo ho lumella betri ho fana ka mefuta e mengata e fapaneng le ea matla a tlase le ka tsela e fapaneng.

Voltage le % E setseng
Sele e 'ngoe le e' ngoe ka har'a betri pakete hangata e sebetsa ho tloha ho 3.0 volts (0% charge) ho fihla ho 4.2 volts (tefiso ea 100%).

Sena se bolela hore pakete ea betri ea 36 V, (e nang le libeteri tse 10 ka letoto) e sebetsa ho tloha ho 30 V (0% tefiso) ho ea ho 42 volts (100% tefiso).U ka bona hore na % e setseng e tsamaellana joang le voltage ea betri (li-scooters tse ling li bonts'a sena ka kotloloho) bakeng sa mofuta o mong le o mong oa betri ho chate ea rona ea matla a betri.

Voltage Sag
Betri e 'ngoe le e' ngoe e tla hlaseloa ke ntho e bitsoang "voltage sag".

Voltage sag e bakoa ke litlamorao tse 'maloa, ho kenyelletsa k'hemistri ea lithium-ion, mocheso le ho hanyetsa motlakase.Kamehla e fella ka boitšoaro bo sa tsitsang ba motlakase oa betri.

Hang ha mojaro o sebelisoa ho betri, motlakase o tla theoha hang-hang.Phello ena e ka lebisa ho khakanyo e fosahetseng ea matla a betri.Haeba u ne u bala matla a betri ka kotloloho, u ne u tla nahana hore u lahlehetsoe ke 10% ea matla a hau kapa ho feta.
