1 Ahoana no fiantsoana hoe "fametrahana haingana" rehefa mamaly? Mametraka ny antso fototra izahay: 1) Haingana ny fiampangana; &39;2) Aza misy fiantraikany amin&39;ny fiainan&39;ny bateria; 3) Andramo ny mitsitsy vola, ohatrinona ny charge elektrika avoaka, andramo ny charging ao amin&39;ny batterie-ko. Haingana ve ianao no afaka miantso haingana? Tsy misy literatiora manara-penitra hanomezana soatoavina manokana, antsoina vonjimaika ny isan&39;ny tokonam-baravarana voatonona ao amin&39;ny politikan&39;ny famatsiam-bola malaza indrindra. Ity tabilao manaraka ity dia ny fenitra famatsiam-bola vaovao ho an&39;ny mpandeha fiara 2017.

Hita fa 3C ny haavon&39;ny fidirana haingana. Raha ny marina, amin&39;ny fenitry ny famatsiam-bola ho an&39;ny fiara mpandeha dia tsy misy fepetra takiana. Avy amin&39;ny fitaovana propagandy amin&39;ny fiara mpandeha amin&39;ny ankapobeny dia hitanao fa amin&39;ny ankapobeny dia azo fenoina amin&39;ny 80% ny olona rehetra azo ampiasaina ho fiampangana haingana, ary hampiakatra azy ireo.

Noho izany, ny fiara mpandeha 1.6c dia mety ho sanda fanondroan&39;ny fiampangana. Araka io hevitra io, ny fampiroboroboana dia 15 minitra feno 80%, izay mitovy amin&39;ny 3.

2C. 2 famandrihana haingana? Amin&39;ity toe-javatra ity, ny antoko mifandraika amin&39;izany dia manaraka lohahevitra ara-batana, ao anatin&39;izany ny bateria, ny charger ary ny fitaovana fitsinjarana herinaratra. Miresaka fiampangana haingana isika, mieritreritra mivantana fa hanana olana ny bateria.

Raha ny marina, alohan&39;ny hisian&39;ny olana ny bateria, ny voalohany dia ny olana amin&39;ny milina famandrihana sy ny tsipika fizarana. Nolazainay ny anton&39;ny fiampangana an&39;ny TSLA, ny anarany dia super charging pile, ny heriny dia 120KW. Araka ny masontsivana Tslamodels85D, 96S75P, 232.

5ah, ny ambony indrindra 403V, ​​1.6C mifanitsy amin&39;ny hery fitakiana ambony indrindra dia 149.9kW.

Hita avy eto fa misy ny fitiliana ny antontam-bolan&39;ny motera elektrika, 1,6C na 30 minitra. Ao amin&39;ny fenitra nasionaly, tsy azo atao ny mametraka mivantana ny toby fiantsonana mivantana ao amin&39;ny tambajotran&39;ny herinaratra ao amin&39;ny trano fonenana.

Taona 1 feno haingana nampiasa herinaratra no nihoatra ny herin&39;ny tokantrano am-polony. Noho izany dia tsy maintsy manangana mpanova 10kV mitokana ny toby fandoavan-ketra, ary tsy vaovao amin&39;ny tobin-tsolika 10kV ny tambajotran&39;ny faritra iray. Dia hoy ny bateria.

Afaka mitondra 1.6C na 3.2C ny batterie, azo jerena amin&39;ny fomba fijery roa ny macro sy micro.

3 Ny lohahevitry ny teoria fiampangana haingana amin&39;ny teoria fiampangana haingana dia antsoina hoe "teoria famandrihana haingana Macroable" satria ny fahaiza-manaon&39;ny bateria haingana dia ny toetra, microstructure, electrolyte akora amin&39;ny fitaovana elektroda anatiny tsara sy ratsy amin&39;ny bateria lithium ion. Additives, fananana diaphragm, sns, ny votoatin&39;ireo micro micro ireo, dia apetraka vetivety eo ivelan&39;ny bateria isika, mahita ny fiampangana haingana ny bateria lithium-ion.

Lithium-ion bateria fanatrehana, ny tsara indrindra fiampangana amin&39;izao fotoana izao tamin&39;ny 1972 Amerikana mpahay siansa Jamas manolotra fa ny bateria dia manana ny tsara indrindra mamaly curve mandritra ny fiampangana, ary ny Mas San Lalàna, dia tokony homarihina fa io teoria io dia natolotra ho an&39;ny lead-asidra bateria, dia mamaritra ny sisin-tanin&39;ny ambony indrindra azo ekena fiampangana amin&39;izao fotoana izao dia ny toe-javatra kely ny fisehoan-javatra sy ny fanehoan-kevitra manokana. Fa ny rafitra dia manana ny vahaolana tsara indrindra, fa ny quiz no izy. Ho an&39;ny bateria lithium ion manokana, ny famaritana ny fetran&39;ny fetran&39;ny ankehitriny azo ekena indrindra dia mety hisy dikany indray.

Miorina amin&39;ny fehin-kevitry ny literatiora fikarohana sasany, ny sandany tsara indrindra dia mbola fironana miolikolika mitovy amin&39;ny lalàna. Tsara ny manamarika fa ny fetra farany ambony indrindra amin&39;ny bateria lithium-ion, ankoatry ny anton-javatra amin&39;ny monomer bateria lithium ion, ankoatry ny anton-javatra amin&39;ny haavon&39;ny rafitra, toy ny fahaiza-manaon&39;ny hafanana, dia samy hafa ny famandrihana ambony indrindra azo ekena amin&39;izao fotoana izao. Avy eo isika dia hanohy ny fifanakalozan-kevitra miaraka amin&39;ity fototra ity.

Famaritana ny raikipohy Maszer: i = i0 * e ^ αt; I0 ​​dia ny charging voalohany amin&39;ny bateria; α dia tahan&39;ny fanekena fandoavana; T dia fotoana fiampangana. Ny sandan&39;ny I0 sy α ary ny karazana bateria, rafitra ary vaovao sy taloha. Amin&39;ity dingana ity, ny fikarohana momba ny fomba famandrihana bateria dia zava-dehibe mifototra amin&39;ny curve famandrihana tsara indrindra.

Araka ny asehon&39;ny sary etsy ambany, raha mihoatra ity curve fiampangana tsara indrindra ity ny charging current, dia tsy ny tahan&39;ny fiampangana ihany no tsy azo ampitomboina, fa hanampy ny habetsaky ny bateria; raha kely noho io curve fiampangana tsara indrindra io, na dia tsy hanimba ny bateria aza, dia hanitatra ny fotoana fiampangana, hampihena ny fahombiazan&39;ny fiampangana. Ny famelabelarana an&39;io teoria io dia misy ambaratonga telo, izay ho an&39;ny dia Masz: 1 ho an&39;ny zotram-pivoahana rehetra, ny rivotry ny fiampangan&39;ny batterie ao amin&39;ny batterie dia mifanohitra amin&39;ny fahafahan&39;ny α sy ny bateria; 2 Momba ny fivoahana nomena Ny habetsahan&39;ny vola, α ary ny ID amin&39;izao fotoana izao dia mitovy; 3 Ny batterie dia avoaka amin&39;ny tahan&39;ny fivoahana samihafa, ary ny IT (fahaizana azo ekena) farany azo alaina amin&39;izao fotoana izao dia ny fitambaran&39;ny kojakoja azo ampiasaina isaky ny tahan&39;ny fivoahana. Ny theorem etsy ambony ihany koa no loharanon&39;ny foto-kevitra momba ny famandrihana ny fahaiza-manaiky.

Fantaro aloha ny atao hoe fandoavana fanekena. Nahita faribolana aho ary tsy hitako ny dikany ofisialy. Araka ny fahatakaranao manokana, ny fahafaha-manaiky ny fiampangana dia ny ambony indrindra amin&39;ny famandrihana bateria azo averina amin&39;ny sarany amin&39;ny fepetra ara-tontolo iainana sasany.

Ny fiantraikan&39;ny azo ekena dia midika fa tsy misy voka-dratsiny izay tsy tokony hisy, tsy misy fiantraikany ratsy eo amin&39;ny fiainana sy ny fahombiazan&39;ny bateria. Fanampin&39;izany, fantaro ireo lalàna telo. Ny lalàna voalohany, aorian&39;ny fandroahana ny batterie, ny fahaiza-manaiky ny famandrihana sy ny habetsaky ny hery ankehitriny, ny ambany ny fiampangana, ny avo kokoa ny fahaiza-manaiky ny fiampangana.

Ny lalàna faharoa, mandritra ny famandrihana, dia afaka manampy ny bateria hanatsara ny sandan&39;ny fanekena amin&39;izao fotoana izao; ny lalàna fahatelo, ny fahaiza-manaiky ny fiampangana dia hohamafisin&39;ny toe-javatra mialoha ny fiampangana sy ny famoahana alohan&39;ny famenoana. Raha toa ka mety ho an&39;ny bateria lithium-ion ihany koa ny Mas, ny fiampangana pulse mivadika (ny anarana manokana dia fomba fiampangana haingana reflex amin&39;ireto manaraka ireto] Ankoatra ny fijerin&39;ny polarization, dia manampy amin&39;ny fanafoanana ny fiakaran&39;ny mari-pana, mavitrika koa i Massea. Fanohanana ny fomba pulse.

Fanampin&39;izay, tena fomba fiampangana marani-tsaina izy io, izany hoe ny fomba fiampangana marani-tsaina, izany hoe niova foana ny sandan&39;ny fiampangana ankehitriny noho ny curve Mascus an&39;ny bateria lithium-ion, ka ny fahombiazan&39;ny fiampangana dia ampitomboina amin&39;ny sisin-tany fiarovana. 4 Fomba fampandehanana haingana haingana Ny fomba fiampangana ny bateria lithium-ion dia manana karazany maro, ho an&39;ny fitakiana fiampangana haingana, ny fomba manan-danja dia misy ny famandrihana pulse, ny famandrihana Reflex, ary ny famandrihana intelligent. Ny karazana bateria samihafa, ny fomba fiampangana azo ampiharina dia tsy mitovy, ary ity fizarana ity dia tsy manavaka manokana amin&39;ity fizarana ity.

Pulse fiampangana Ity dia fomba fiampangana pulse avy amin&39;ny literatiora, ary ny dingana pulse dia omena aorian&39;ny fikasihana fiampangana ary ny fetra farany ambony dia 4.2V, ary mitohy mihoatra ny 4.2V.

Aza lazaina ny rationality ny toe-javatra voafaritra manokana, samy hafa karazana batch manana fahasamihafana. Mandinika ny fizotran&39;ny fampiharana pulse izahay. Ity ambany ity ny curve fiampangana pulse, ary zava-dehibe ny mampiditra dingana telo: precharge, famandrihana tsy tapaka ary famandrihana pulse.

Ny famandrihana ny batterie amin&39;ny kojakoja tsy tapaka mandritra ny famandrihana tsy tapaka, ny angovo ampahany dia afindra ao anaty batterie. Mgbe voltaji batrị na-ebili na voltaji dị elu (4.2V), banye n&39;ụdị chaja pulse: na-ebu batrị ugbu a nke 1C.
