Kune akati wandei mabhatiri uye tekinoroji yekuchaja iyo inofanirwa kutariswa kana ichichinjika kune electromobility mukuchera pasi pevhu.
Motokari dzemigodhi dzine bhatiri dzakanyatsokodzera kuchera pasi pevhu.Nekuda kwekuti havabudise magasi anopedza simba, vanoderedza kutonhora uye kufefetera zvinodiwa, vanocheka greenhouse gasi (GHG) kuburitsa uye mari yekugadzirisa, uye kugadzirisa mamiriro ekushanda.
Zvinenge zvese midziyo yemugodhi yepasi pevhu nhasi ine simba redhiziri uye inogadzira utsi hwekuburitsa.Izvi zvinofambisa kudiwa kweakawanda masystem ekufemesa kuti achengetedze kuchengetedzeka kwevashandi.Uyezve, sevashandisi vemigodhi vanhasi vari kuchera zvakadzika se4 km (13,123.4 ft.) kuti vawane madhipoziti ematombo, masisitimu aya anokura zvakanyanya.Izvi zvinovaita kuti vawedzere kudhura kuisa uye kumhanya uye kuwedzera nzara yesimba.
Panguva imwecheteyo, misika iri kuchinja.Hurumende dziri kuisa zvinangwa zvezvakatipoteredza uye vatengi vari kuwedzera kuda kubhadhara mari yepamusoro yezvigadzirwa zvekupedzisira zvinogona kuratidza yakaderera kabhoni tsoka.Izvi zviri kugadzira kufarira kwakawanda mumigodhi ye decarbonizing.
Kurodha, kuburitsa, uye kurasa (LHD) michina mukana wakanaka wekuita izvi.Vanomiririra chikamu che80% chesimba rinodiwa kumigodhi yepasi pevhu sezvavanofambisa vanhu nemidziyo nemugodhi.
Kuchinjira kumotokari dzinofambiswa nebhatiri kunogona kuita decarbonize migodhi uye kurerutsa masisitimu ekufemesa.
Izvi zvinoda mabhatiri ane simba guru uye nguva refu - basa raive kunze kwekugona kwehunyanzvi hwekare.Nekudaro, kutsvagisa nekusimudzira mumakore mashoma apfuura kwakagadzira rudzi rutsva rwemabhatiri e-lithium-ion (Li-ion) ane mwero wakakodzera wekuita, chengetedzo, kukwanisa uye kuvimbika.
Kutarisira kwemakore mashanu
Kana vashandisi vakatenga michina yeLHD, vanotarisira hupenyu hwemakore mashanu zvakanyanya nekuda kwekuoma kwemamiriro.Machina anofanirwa kutakura mitoro inorema maawa makumi maviri nemana pazuva munzvimbo dzisina kuenzana nehunyoro, huruva nematombo, kuvhunduka kwemuchina uye kudedera.
Kana zvasvika kune simba, vashandisi vanoda mabhatiri masisitimu anofanana nehupenyu hwemuchina.Iwo mabhatiri anodawo kumira kazhinji uye yakadzika kuchaja uye kuburitsa ma cycles.Ivo zvakare vanofanirwa kuve vanokwanisa kukurumidza kuchaja kuti vawedzere kuwanikwa kwemotokari.Izvi zvinoreva maawa mana ebasa panguva, achienderana nehafu yezuva rekuchinja maitiro.
Kuchinja-chinja kwebhatiri maringe nekuchaja nekukurumidza
Battery-kuchinjanisa nekuchaja nekukurumidza kwakabuda senzira mbiri dzekuzadzisa izvi.Kuchinja-chinja kwebhatiri kunoda mabhatiri maviri akafanana - imwe inogonesa mota uye imwe ichichaja.Mushure mekuchinja kwemaawa mana, bhatiri rinoshandiswa rinotsiviwa nerichangobva kuchajwa.
Chakanakira ndechekuti izvi hazvidi kuchaja magetsi epamusoro uye zvinokwanisa kutsigirwa nemagetsi emugodhi aripo.Zvisinei, kuchinja kunoda kusimudza uye kubata, izvo zvinogadzira rimwe basa.
Imwe nzira ndeyekushandisa bhatiri rimwe chete rinokwanisa kuchaja nekukurumidza mukati memaminitsi gumi panguva yekumbomira, kutyora uye kuchinja kwekuchinja.Izvi zvinobvisa kukosha kwekuchinja mabhatiri, zvichiita kuti hupenyu huve nyore.
Zvakadaro, kuchaja nekukurumidza kunotsamira pakubatanidza giridhi rine simba guru uye vashandisi vemigodhi vangangoda kukwidziridza zvivakwa zvavo zvemagetsi kana kuisa nzira yekuchengetedza magetsi, kunyanya kune zvikepe zvakakura zvinoda kuchaja panguva imwe chete.
Li-ion chemistry yekuchinja kwebhatiri
Sarudzo pakati pekuchinjanisa nekuchaja nekukurumidza inozivisa kuti ndeupi rudzi rwebhatiri kemikari yekushandisa.
Li-ion ishoko reamburera rinofukidza huwandu hwakawanda hwe electrochemistries.Izvi zvinogona kushandiswa zvega kana kusanganiswa kuendesa hupenyu hunodiwa kutenderera, hupenyu hwekarenda, simba remagetsi, kuchaja nekukurumidza, uye kuchengeteka.
Mabhatiri mazhinji eLi-ion anogadzirwa negraphite segerodhi isina kunaka uye ane zvinhu zvakasiyana seye electrode yakanaka, senge lithium nickel-manganese-cobalt oxide (NMC), lithium nickel-cobalt aluminium oxide (NCA) uye lithium iron phosphate (LFP). )
Pakati peizvi, NMC neLFP zvese zvinopa yakanaka simba remukati ine yakakwana yekuchaja kuita.Izvi zvinogadzira imwe yeiyi yakanakira kuchinjanisa bhatiri.
Chemistry nyowani yekuchaja nekukurumidza
Kuchaja nekukurumidza, imwe nzira inoyevedza yabuda.Iyi lithium titanate oxide (LTO), iyo ine electrode yakanaka yakagadzirwa kubva kuNMC.Panzvimbo yegraphite, iyo yakaipa electrode yakavakirwa paLTO.
Izvi zvinopa mabhatiri eLTO maitiro akasiyana.Vanogona kugamuchira kuchaja kwesimba rakakwirira kwazvo kuitira kuti nguva yekuchaja iite shoma semaminitsi gumi.Ivo vanogona zvakare kutsigira katatu kusvika kashanu kubhadharisa uye kuburitsa matenderedzwa kupfuura mamwe marudzi eLi-ion chemistry.Izvi zvinoturikira kuva hupenyu hwekarenda hurefu.
Pamusoro pezvo, LTO ine yakanyanyisa kuchengetedzwa kwemukati sezvo ichikwanisa kumirisana nekushungurudzwa kwemagetsi sekuyerera kwakadzika kana maseketi mapfupi, pamwe nekukuvara kwemuchina.
Battery management
Chimwe chakakosha dhizaini yeOEMs ndeyemagetsi yekutarisa uye kutonga.Ivo vanofanirwa kubatanidza mota nebhatiri manejimendi system (BMS) inodzora kuita uku ichidzivirira chengetedzo mukati mese system.
Iyo yakanaka BMS inodzorawo kubhadharisa uye kuburitswa kwemaseru ega ega kuchengetedza tembiricha isingaperi.Izvi zvinogonesa kuita kwakafanana uye zvinowedzera hupenyu hwebhatiri.Ichapawo mhinduro pamusoro pemamiriro ekubhadhara (SOC) uye mamiriro ehutano (SOH).Izvi zviratidzo zvakakosha zvehupenyu hwebhatiri, neSOC inoratidza kuti inguva yakareba sei mushandisi anogona kumhanyisa mota panguva yekuchinja, uye SOH ichive chiratidzo chehupenyu hwasara hwekarenda.
Plug-uye-kutamba kugona
Kana zvasvika pakutsanangura mabhatiri masisitimu emota, zvine hungwaru kushandisa mamodule.Izvi zvinofananidzwa neimwe nzira yekubvunza vanogadzira mabhatiri kuti vagadzire mabhatiri akagadzirirwa masisitimu emota yega yega.
Kubatsira kukuru kweiyo modular maitiro ndeyekuti maOEM anogona kugadzira yakakosha chikuva chemota dzakawanda.Ivo vanogona kuwedzera bhatiri module munhevedzano kuvaka tambo dzinoendesa inodiwa voltage kune yega yega modhi.Izvi zvinotonga kubuda kwemagetsi.Ivo vanogona ipapo kusanganisa tambo idzi mukufanana kuvaka inodiwa simba rekuchengetedza simba uye nekupa iyo inodiwa nguva.
Mitoro inorema iri kutamba mumigodhi yepasi inoreva kuti motokari dzinoda kuendesa simba guru.Izvo zvinoda mabhatiri masisitimu akaiswa pa650-850V.Nepo kukwidziridza kumagetsi epamusoro kwaizopa simba repamusoro, zvinozotungamira kumitengo yakakwira system, saka zvinotendwa masisitimu acharamba ari pasi pe1,000V mune ramangwana rinoonekwa.
Kuti uwane maawa mana ekuenderera mberi kwekushanda, vagadziri vanowanzotsvaga simba rekuchengetedza simba re200-250 kWh, kunyange zvazvo vamwe vachada 300 kWh kana kupfuura.
Iyi modular nzira inobatsira maOEM kudzora mitengo yekusimudzira uye kuderedza nguva yekutengesa nekudzikisa kudiwa kwekuyedzwa kwemhando.Tichifunga nezveizvi, Saft yakagadzira plug-uye-kutamba bhatiri mhinduro inowanikwa muNMC neLTO electrochemistries.
Kuenzanisa kunoshanda
Kuti unzwe kuti ma module anofananidzwa sei, zvakakodzera kutarisa maviri mamwe mamiriro eiyo yakajairwa LHD mota yakavakirwa pabhatiri-swapping uye nekukurumidza-kuchaja.Muzviitiko zviviri izvi, motokari inorema matani makumi mana neshanu isina kutakurwa uye matani makumi matanhatu akaremerwa zvakakwana nemutoro we6-8 m3 (7.8-10.5 yd3).Kugonesa kuenzanisa-kwe-kufanana, Saft yakawona mabhatiri ehuremu hwakafanana (3.5 matani) uye vhoriyamu (4 m3 [5.2 yd3]).
Muchiitiko chekuchinja-bhatiri, bhatiri rinogona kunge rakavakirwa paNMC kana LFP chemistry uye raizotsigira 6-awa LHD shanduko kubva pahukuru uye huremu envelopu.Iwo mabhatiri maviri, akaiswa pa650V aine 400 Ah kugona, angada kuchaja kwemaawa matatu kana achinja mota.Imwe neimwe yaizogara 2,500 mitsara pamusoro pehupenyu hwekarenda hwemakore 3-5.
Pakuchaja nekukurumidza, bhatiri repaboard LTO rezviyero zvakafanana raizoyerwa ku800V ne250 Ah huwandu, richiunza maawa matatu ekushanda ne15-maminetsi ekupedzisira-nekukurumidza kuchaja.Nekuti iyo chemistry inokwanisa kutsungirira mamwe akawanda ma cycles, yaizounza zviuru makumi maviri, nehupenyu hunotarisirwa hwekarenda hwemakore mashanu-7.
Munyika chaiyo, mugadziri wemotokari anogona kushandisa nzira iyi kusangana nezvinodiwa nemutengi.Semuenzaniso, kurebesa nguva yekuchinja nekuwedzera simba rekuchengetedza simba.
Flexible design
Pakupedzisira, vanozove vashandi vemugodhi vanosarudza kuti vanoda kuchinjanisa bhatiri kana kukurumidza kuchaja.Uye sarudzo yavo inogona kusiyana zvichienderana nesimba remagetsi uye nzvimbo inowanikwa pane imwe neimwe yenzvimbo dzavo.
Naizvozvo, zvakakosha kuti vagadziri veLHD vavape iyo inoshanduka yekusarudza.
