Nganye kwezi khemistri zebhetri imele urhwebo phakathi kokhuseleko, ubomi obude, umthamo, kunye nemveliso yangoku.

I-Lithium Manganese (INR, NMC)
Ngethamsanqa, uninzi lwee-scooters zombane ezisemgangathweni zisebenzisa i-INR yebhetri yekhemistri - enye yezona khemistri zikhuselekileyo.Le bhetri inika umthamo ophezulu kunye nemveliso yangoku.Ubukho be-manganese bunciphisa ukuchasana kwangaphakathi kwebhetri, ukuvumela imveliso yangoku ephezulu ngelixa igcina amaqondo obushushu aphantsi.Ngenxa yoko, oku kunciphisa amathuba okubaleka kwe-thermal kunye nomlilo.

Ezinye ii-scooters zombane ezine-INR chemistry ziquka i-WePed GT 50e kunye neemodeli ze-Dualtron.

Lead-asidi
I-Lead-asidi yikhemistri yebhetri endala kakhulu edla ngokufumaneka kwiimoto kunye nezinye izithuthi zombane ezinkulu, njengeenqwelo zegalufa.Zikwafumaneka kwezinye ii-scooters zombane;okona kubalulekileyo, ii-scooters zabantwana ezingabizi kakhulu ezivela kwiinkampani ezinjengeRazor.

Iibhetri ze-lead-asidi zinenzuzo yokungabizi, kodwa zithwaxwa kukuxinana kwamandla asezantsi, okuthetha ukuba banobunzima obuninzi xa kuthelekiswa nomthamo wamandla eziwagcinayo.Ngokuthelekisa, iibhetri ze-Li-ion zine-10X yobuninzi bamandla xa kuthelekiswa neebhetri ze-lead-acid.

Ibhetri Packs
Ukwakha ipakethe yebhetri kunye namakhulu okanye amawaka eeyure zewatt amandla, iiseli ezininzi ze-18650 zeLi-ion zihlanganiswe kunye zibe yisakhiwo esifana nezitena.Ipakethi yebhetri efana nezitena ibekwe esweni kwaye ilawulwa yisekethe yombane ebizwa ngokuba yinkqubo yokulawula ibhetri (BMS), elawula ukuhamba kombane ukungena nokuphuma ebhetri.
Iiseli zomntu ngamnye kwipakethi yebhetri ziqhagamshelwe kuthotho (ekupheleni ukuya esiphelweni) ezihlanganisa amandla azo.Le yindlela enokwenzeka ngayo ukuba nee-scooters ezine-36 V, 48 V, 52 V, 60 V, okanye iipakethi zebhetri ezinkulu.

Ezi ntambo zomntu ngamnye (iibhetri ezininzi kwi-series) zidibene ngokuhambelanayo ukwandisa imveliso yangoku.

Ngokulungelelanisa inani leeseli kuthotho kunye nokuhambelana, abavelisi be-scooter yombane banokonyusa amandla ombane ophumayo okanye umthamo wangoku kunye neyure ye-amp.

Ukutshintsha ubumbeko bebhetri akuyi kwandisa amandla ewonke agciniweyo, kodwa kuvumela ngokufanelekileyo ibhetri ukuba ibonelele ngoluhlu oluthe kratya kunye nombane ophantsi kwaye ngokuphambeneyo.

I-Voltge kunye ne-% eseleyo
Iseli nganye kwipakethi yebhetri isetyenziswa ngokubanzi ukusuka kwi-3.0 volts (i-0% intlawulo) yonke indlela ukuya kwi-4.2 volts (i-100% intlawulo).

Oku kuthetha ukuba ibhetri ye-36 V, (kunye neebhetri ze-10 kwichungechunge) iqhutywe kwi-30 V (i-0% intlawulo) ukuya kwi-42 volts (i-100% intlawulo).Uyakwazi ukubona ukuba i-% eseleyo ihambelana njani nombane webhetri (ezinye ii-scooters zibonisa oku ngokuthe ngqo) kulo lonke uhlobo lwebhetri kwitshathi yethu yombane webhetri.

I-Voltage Sag
Yonke ibhetri iya kubandezeleka ngenxa yento ebizwa ngokuba yi-voltage sag.

I-Voltage sag ibangelwa yimiphumo emininzi, kuquka i-lithium-ion chemistry, ubushushu, kunye nokumelana nombane.Ihlala iphumela ekuziphatheni okungahambelaniyo kombane webhetri.

Ngokukhawuleza ukuba umthwalo usetyenziswe kwibhetri, i-voltage iya kuhla ngokukhawuleza.Esi siphumo sinokukhokelela ekuthelekeleleni ngokungalunganga umthamo webhetri.Ukuba ubufunda ngokuthe ngqo amandla ombane ebhetri, ungacinga ukuba ulahlekelwe ngoko nangoko nge-10% yomthamo wakho okanye ngaphezulu.

Emva kokuba umthwalo ususiwe amandla ombane webhetri uya kubuyela kwinqanaba lokwenyani.

Ukuwohloka kwe-voltage kwenzeka ngexesha lokukhupha ibhetri ixesha elide (njengexesha lohambo olude).Ikhemistri ye-lithium kwibhetri ithatha ixesha elithile ukuze ibambe izinga lokukhutshwa.Oku kunokubangela ukuba amandla ombane ebhetri ehle ngokukhawuleza ngakumbi ngexesha lokuphela komsila wohambo olude.

Ukuba ibhetri ivunyelwe ukuba iphumle, iya kubuyela kwinqanaba lombane lokwenyani nelichanekileyo.

Amanqaku oMmandla
Umthamo webhetri ye-e-scooter uthelekelelwa kwiiyunithi zewatt iiyure (isifinyezo Wh), umlinganiselo wamandla.Le yunithi kulula ukuyiqonda.Umzekelo, ibhetri enomlinganiselo we-1 Wh igcina amandla awoneleyo ukunika iwathi enye yamandla ngeyure enye.

Umthamo wamandla othe kratya uthetha iiyure ze-watt eziphezulu zebhetri nto leyo eguqulela kuluhlu olude lwesithuthuthu sombane, kwisayizi yemoto enikiweyo.I-avareji ye-scooter iya kuba nomthamo ojikeleze i-250 Wh kwaye ikwazi ukuhamba malunga neemayile ezili-10 kumyinge weemayile ezili-15 ngeyure.Izithukuthuku ezisebenza ngokugqithisileyo zinokuba nomthamo ofikelela kumawaka eeyure ze-watt kunye noluhlu oluya kuthi ga kwiimayile ezingama-60.

Iimpawu zebhetri
Iiseli ze-Li-ion zomntu ngamnye kwi-e-scooter yebhetri ye-e-scooter zenziwe ziinkampani ezimbalwa ezahlukeneyo ezaziwayo kumazwe ngamazwe.Iiseli ezikumgangatho ophezulu zenziwe yi-LG, Samsung, Panasonic, kunye neSanyo.Ezi ntlobo zeeseli zikholisa ukufumaneka kuphela kwiipakethi zeebhetri zee-scooters eziphezulu.

Uninzi lohlahlo lwabiwo-mali kunye nezithuthuthu zombane zabahambi zineepakethi zebhetri ezenziwe kwiiseli ezenziwe zamayeza eTshayina, ezohluka kakhulu kumgangatho.

Umahluko phakathi kwee-scooters ezine-brand cell kunye ne-generic yaseTshayina sisiqinisekiso esikhulu solawulo lomgangatho kunye neebrendi ezisekiweyo.Ukuba oko akukho kuhlahlo lwabiwo-mali lwakho, ke qiniseka ukuba uthenga i-scooter kumenzi ohloniphekileyo osebenzisa iindawo ezisemgangathweni kwaye unemilinganiselo yokulawula umgangatho omhle (QC) endaweni.

Eminye imizekelo yeenkampani ezinokuthi zibe ne-QC elungileyo yi-Xiaomi kunye ne-Segway.
