Intshayelelo yeBhayikhi yoMbane yebhetri

Ibhetri yebhayisikili yombane ifana nentliziyo yomzimba womntu, eyona nto ibaluleke kakhulu kwi-e-Bike.Inegalelo elikhulu kwindlela eqhuba kakuhle ngayo ibhayisekile.Nangona ubukhulu kunye nobunzima obufanayo, iyantlukwano kwisakhiwo kunye nokwakheka kusezizizathu zokuba iibhetri zenza ngokwahlukeneyo.
Into esiyibonileyo ezona ntlobo zidumileyo zebhetri kule mihla ziibhetri zeLead-acid kunye neebhetri zeLithium-ion.

Ukusukela ekuphuhlisweni kwayo kwasekuqaleni ngeminyaka yoo-1950, oku kube yeyona nto isebenzayo kwaye isetyenziswa kakhulu ubuchwepheshe bebhetri kwimbali.Iibhetri ze-lead-acid zisetyenziswa ngokuqhelekileyo kwi-UPS, iibhetri zemoto, njl.

Ibhetri ye-lead-acid izuze udumo lwayo ngokusebenza kakuhle kwiindawo eziphezulu zokushisa kunye nokunyamezela ukusetyenziswa kakubi.Ngombulelo kolu phawu, iibhayisekile zombane ezineebhetri ze-lead-asidi zibonisa ukusebenza okungcono kwiimeko zendlela ezirhabaxa, kunye nesantya esisezantsi sokugcinwa kwebhetri.

Iziqulatho ze-asidi zinokudlulisela ukushisa ngaphandle kwaye zincinci ukuba zome, ukugcina imeko efanelekileyo yokusebenza.Ine malunga ne-500 imijikelo yentlawulo ngaphambi kokuba ifike esiphelweni sobomi.Nangona kunjalo, esi sakhiwo sigcina ibhetri inzima kwaye i-clumsy, ephela ngobunzima obuphezulu be-e-bike.

Zonke iintlobo zebhetri ziye zathwaxwa yimicimbi yokuzikhupha, nto leyo ethetha ukuba ilahlekelwa yijusi nokuba ingasetyenziswa.Ibhetri ye-lead-acid inezinga eliphantsi lokuzikhupha elivumela ukuba likhuphe kakuhle kwaye ngokuthe ngcembe.Ngakolunye uhlangothi, ibhetri ye-lead-acid idinga ixesha elikhethekileyo lokutshaja ixesha elide malunga neeyure ze-8-10 kwaye umthamo wayo ophezulu usisiqingatha kuphela sebhetri ye-lithium-ion.

Usenokuba ubonile iindidi ezininzi zeebhetri ze-lithium-ion ezisetyenziswa ngokuqhelekileyo ngamashishini ahlukeneyo ebhayisikile yombane kunye nabavelisi.I-Lithium-ion sisixhobo esihle kakhulu sokutshaja umbane okhawulezayo kunye nexesha elincinci lokutshaja, ubungakanani obubhetyebhetye obuncinci, kunye nobomi obude kunebhetri yeasidi.

Siye sashwankathela ezinye iintlobo zebhetri ze-lithium eziqhelekileyo ezisetyenziswayo kwiIYunivesithi yebhetriy.

Iresiphi ye-NMC kukuxuba i-Nickel kunye neManganese.I-Nickel idume ngamandla ayo athile aphezulu kodwa uzinzo olubi;I-manganese inenzuzo yokwenza isakhiwo esikhethekileyo ukufumana ukuchasana okuphantsi kwangaphakathi kodwa ihambisa amandla athile ahluphekileyo.Ukudibanisa isinyithi kunceda ukunciphisa ukusilela kunye nokwandisa amandla omnye komnye.

I-NMC iye yaba yibhetri ekhethwayo kwii-e-bikes, izixhobo zamandla ombane, kunye nee-powertrains.Oku kubonelela ngeendleko eziphantsi zezinto ezibonakalayo ngenxa yokunciphisa ukusetyenziswa komxholo obiza kakhulu we-cobalt.

Ixesha lokutshaja ngokuqhelekileyo iiyure ze-3 kunye nokukwazi ukufikelela kwi-1000-2000 imijikelezo.

Ngokwe-brand yebhayisekile yombane yaseMelika eyaziwayoSuper73, i-NMC ikwaluhlobo olunye lwebhetri abalusebenzisileyo kuzo zonke iimodeli ezidumileyo.

Emva kophando oluninzi kunye novavanyo,Teslaigqibe kwelokuba ikhethe i-NMC njengohlobo lwayo oluphambili lwebhetri kwaye iphuhlise ibhetri ye-18650.

Izimvo:
Ixabiso elisebenzayo, Umthamo ophezulu, amandla aphezulu

Ngaphandle komlinganiselo ophezulu wangoku kunye nobomi bomjikelo omde, i-LFP ikwabonelela ngozinzo oluhle lobushushu, ukhuseleko olomeleziweyo, kunye nokunyamezelana kokuxhatshazwa.Ngobuninzi be-2000 cycle counts kunye nokushisa kwe-thermal ebalekayo ephezulu ye-270 ° C, i-LFP iphume ngaphandle kwezinye iibhetri ze-Lithium-ion ekuzinzeni kwesicelo ukuba ibe yinto ekhuselekileyo.I-LFP inexabiso eliphantsi kwimveliso, ngenxa yokuba isoloko isetyenziswa njengokutshintsha ibhetri ye-lead-acid.

Ifuna iiyure ezi-3 ukubiza ngokupheleleyo.
Kwizinto eziphathwayo nezimileyo ezifuna imisinga yomthwalo ophezulu kunye nonyamezelo, i-LFP ayinakuphikiswa lolona khetho lulungileyo.

Izimvo:
Ireyithingi ephezulu yangoku, Ubomi bomjikelo omde, uzinzo olulungileyo lwe-thermal, ukhuseleko olomeleziweyo, Ukunyamezelana ukuba kusetyenziswe kakubi;
Ukuzikhupha okuphezulu, umthamo ophantsi

Kuqhelekile ukufumana iibhetri zeLithium Cobalt Oxide kwiifowuni eziphathwayo, iilaptops, kunye neekhamera zedijithali ngenxa yamandla athile aphezulu aphethwe yi-LCO.

Xa kuthelekiswa ne-LEP, ayizinzile kangako ngenxa yobuntununtunu obuphezulu beqondo lobushushu njengoko indawo yokubaleka ye-thermal ijikeleze i-150 ° C (302 ° F).

Ngokumalunga nobunzulu bokukhutshwa, umthwalo, kunye nobushushu, ibhetri ye-LCO ihambisa imijikelo yentlawulo kwindawo ethile phakathi kwe-500-1000.Loo nto yenza ukuba olu hlobo lwebhetri lubenobomi obufutshane.
Iswele amandla athile okuthwala umthamo omkhulu womthwalo, okuthetha ukuba ayiyobhetri igqibeleleyo yeebhayisekile zihlala zithwele abantu okanye imithwalo.
Ngaphandle koko, iiyure ezi-3 ziyafuneka ukuze ibhetri igcwale ngokupheleleyo.

Izimvo:
Amandla athile aphezulu kakhulu;
Ubomi obufutshane, uzinzo oluphantsi lwe-thermal, Umthamo olinganiselweyo womthwalo (amandla athile), Uhlobo oluduru

Umthamo wayo umalunga nesibini kwisithathu se-LCO.

Ubhetyebhetye olugqwesileyo kuyilo lwenza abavelisi basebenzise okona kulungileyo ubomi obude, ubuninzi bomthwalo wangoku (amandla athile), okanye umthamo ophezulu (amandla athile) kwibhetri.Umzekelo, ukutshintsha ukusuka kwinguqulelo yobomi obude, umthamo unokunyuswa ukusuka kwi-1,100mAh ukuya kwi-1,500mAh kwinguqulelo yomthamo ophezulu.

Nangona kunjalo, ibhetri ye-LMO inokuhamba kuphela kwimijikelezo yokutshaja engama-300-700 ngenxa yovakalelo kubunzulu bokukhutshwa kunye nobushushu.

Izimvo:
Ukutshaja ngokukhawuleza;
Ukukhutshwa okuphezulu kwangoku, Umthamo omncinci

Kwiibhetri ezininzi, imeko yemozulu eshushu nebandayo inciphisa ukusebenza.Ke kunqande ukusebenzisa ibhayisekile ye-elektroniki ngexesha lobushushu obugqithisileyo ehlotyeni okanye kwiintsuku zasebusika.Landela imiyalelo enikelwe ngumenzi wakho.

Kuphephe amagingxigingxi amabala, imingxuma emingxunyeni, izigingqi zesantya eziya kubangela ukothuka okanye ukungcangcazela kwebhetri.Kusebenza umgaqo ofanayo xa uphethe ibhetri esuswayo.

Kuphephe ukubiza iyunithi yakho kwangoko emva kokuqhuba.

Vumela ixesha elithile ukuba ibhetri iphole endaweni yokuyigcina kubushushu obuphezulu.Ngokuchaseneyo, umgaqo ofanayo ukwasebenza xa ugqibile ukutshaja.

Sebenzisa itshaja elungileyo okanye iadaptha ebonelelwe ngumenzi.Iyunithi yokutshaja engahambelaniyo inokubangela umonakalo osisigxina kwibhetri yakho.

Musa ukuyishiya itshaja iplagi xa ugqibile ukutshaja.

Ubushushu bokugcina obuphezulu, kunye neqabaka, bufutshane ubomi benkonzo.

Musa ukugcina ibhetri yakho ngaphandle apho inokuveza ubushushu, ukubanda (ngaphantsi kwe-0), ifumile.

Musa ukukhupha ngaphantsi kwe-20% yomthamo.

Ngaphambi kokubeka ibhetri kwindawo yokugcina ixesha elide, funda ngononophelo imenyu yomsebenzisi kwaye ulandele imiyalelo ekhuthazwa ngumenzi.
