Ndeipi bhatiri rakanakisa rekuchengetedza simba repamba?

Motokari dzemagetsi dzakachena dzinotyairwa nesimba remagetsi. Panyaya yechiyero, ivo vanovimbawo nekuwedzera kwe lithium mabhatiri maererano nekuchengetedza simba. Kunyanya, kune kumwe kuenzanisa pakati pezviviri maererano nehupfumi hwese uye hupenyu hurefu.

1) Ongororo yehupenyu bvunzo mamiriro ekuchengetedza simba bhatiri

Iyi nhevedzano yemiedzo muAustralia, kusanganisira tsvakiridzo huru yekutsiviwa kwemabhatiri e-lithium uye mabhatiri e-lead-acid. Yagara kwenguva refu. Iyi data inotibatsirawo kuti tinzwisise iyo yakafanana makemikari system mumashandisirwo akafanana. Kuora kwehupenyu

Nzvimbo yekuongorora mabhatiri yakavakaStainableSkillsTrainingHubattheCanberraInstituteof Technology uye kuyedza mashandiro ebhatiri yatanga.Muchidimbu izvi zvinosanganisira:Kutenderera mabhatiri katatu pazuva kubva pamakore matatu kutevedzera makore mapfumbamwe’akakosha’mazuva ese’mabhatiri akawedzera kukurumidza kukurumidza kwebhatiri

Kutevedzera’zvimiro’zvenyika chaiyo’nekutenderedza tembiricha yenzvimbo iyo mabhatiri achaiswa; uye,

Tichifunga nezvezviviri zviri pamusoro apa, kutenderera katatu pazuva, nekuchinja kwekushisa kwakawedzerwa, kupisa muzhizha 2 kutonhora 1, kutonhora muchando 2 kupisa 1, uye tembiricha inosarudzwa pa10-35degC.

Kutsikisa data rekuita, kusanganisira mabhatiri’ adzikira musimba rekuchengetedza mumakore matatu ekuedzwa

Heano mabhatiri ekuchengetedza simba eTesla andiri kufarira, pamwe ne LG uye Samsung’s NCM mabhatiri (danho rekutanga rekuyedza)

Mazwi: Kuchengetedzwa kwesimba kweSamsung kwakafanana nemabhatiri emotokari. Nekuda kwezvinodiwa zvekuchengetedza simba, kune zvimwe zvinotariswa zvekugadzirwa kwehupenyu hwekutenderera.

Mhinduro dzekutanga dzebvunzo

1) Capacity attenuation

2) Attenuation maitiro ekutanga

Pamusoro pekutanga kupera kweAVIC lithium bhatiri, Tesla’s cylindrical bhatiri cell cycle hupenyu hwakashata.

Mune ino nhevedzano yemishumo, kune maviri ebvunzo matafura, anosanganisira huwandu hwematenderedzwa ehupenyu, imwe inoedzwa kusvika makumi masere, imwe ndeye 80 mitsetse.

Mazwi: Imwe yematafura maviri ndiyo nzira yekuverenga simba inoshandiswa. Dhiagiramu inotevera haina yunifomu, asi inopa chete fungidziro yeSOH. Zvinofungidzirwa kuti izvi zvinoshandurwa nekubudirira kwekutanga kwekuisa uye kubuda simba.

Kubva pane iyi chati, LG uye SDI dziri mu attenuation yakakodzera curve. Pa800, iyo attenuation inenge 8%.

Tesla’s data, 800 nguva padyo ne85%

Lead-asidhi mabhatiri uye CALB (AVIC’s) haigone kumira mushure menguva dzinosvika mazana mana.

Kuwedzera kuedza

Panguva dze1100, Tesla’s Powerwall yakapinda muyero pazasi 80%

LG mabhatiri anodonha pazasi 90% panguva 1,000 nguva. Iyi ndiyo simba rekuchengetedza bhatiri system ine yakanyanya simba density pakati pese.

Masero makuru eSDI achiri akatenderedza 92% mushure memazana zana nemakumi mana, akaenzana nea Sony’s.

Muchikamu chechipiri chebvunzo, zvimwe zvigadzirwa zvakati wandei zvakasarudzwa, iyo yakagadziridzwa TeslaPowerwall2 yakawedzerwa, uye LG chizvarwa chitsva chemagetsi ekuchengetedza mabhatiri akagadziridzwa.

Miedzo yechikamu chechipiri ichiri kuenderera mberi, uye inofungidzirwa kuti nguva dzinopfuura 1000 dzinogona kuwanikwa kuti uwane mhedzisiro yakajeka.

Mabhatiri eZTE anoora nekukurumidza, zvishoma zvirinani pane SimpliPhi muUnited States

Lithium iron phosphate uye NCM111 ichine mhedzisiro yakafanana mukutenderera

2) Kuongorora kwehupfumi hwekuchengetedza simba

Nekuwedzera kwekukurumidza kwehukuru hweindasitiri, makemikari ekuchengetedza simba parizvino ndeimwe yemagetsi ekuchengetedza simba nekukurumidza kuderera kwemutengo. Lithium-ion mabhatiri uye lead-asidhi mabhatiri anoshandiswa sebhenji tekinoroji; iyo yeruzivo curve nzira inoshandiswa kufanotaura kudzika kwemaitiro akasiyana ekuchengetedza simba Ⅶ, uye akasiyana ehunyanzvi ruzivo macurves anowanikwa nekuongorora nhoroondo data.

Parizvino, mutengo wepombi yekuchengetedza ndiyo yakaderera, ine unit simba rekuchengetedza mari inosvika 770 yuan; mutengo wemabhatiri e-lead-asidhi wakakwira zvishoma, pa900 yuan/kWh; mutengo wemabhatiri emagetsi emagetsi emagetsi uye lithium-ion mabhatiri ekuchengetedza simba akafanana, pa1550-1600 yuan / kWh Nguva. Nekudaro, maererano nekuderera kwemutengo, mutengo wemabhatiri emagetsi uye lithium-ion mabhatiri ekuchengetedza simba wadonha nekukurumidza.

Remarks Iyo data sosi ndeye “Kudzidza pane Inogoneka uye Economics yeMagetsi Vehicle Energy Storage Technology”. Chidzidzo chacho chinoshandisa nonlinear regression analysis kuti ikwane hukama huripo pakati pekuwanda kwekubuda kwemabhatiri emagetsi uye mari yekudyara, uye regression equation inotora simba rekushanda fomu17. Iko kusavimbika kwekufanotaura kunoratidzwa neyakajairwa kukanganisa σ kweiyo yekufanotaura, kureva, iyo 95% yekuvimbika nguva yenguva yeempirical rate yekufungidzira ndeye 1.96 × σ.

Zuva rekutanga rekuyera mutengo wekufanotaura kweyakabviswa simba rekuchengetedza bhatiri ndeye 2021, uye mutengo wayo unodzikira trajectory inoratidza kuderera nekukurumidza pakutanga, uyezve kudzikira kwakakosha. Kubatsira kwemutengo wakaderera wekutenga mabhatiri akabviswa padanho rekutanga uye kuderera kunononoka mumutengo wekupedzisira wekushandisa . Kubva pamaonero eLCOS, iyo yepamusoro-ku-mupata parity nguva yekuregedzerwa bhatiri rekuchengetedza simba ndeye 2025, uye mwero wekuderera kwemutengo unobva wanyanya kushomeka.

pfupiso:
Tichifunga nezve kutenderera chaiko mumunda wekuchengetedza simba, zvinogoneka kuti mabhatiri matsva anoda imwezve mutengo optimization, uye hazvisi zvechokwadi kusarudza mabhatiri akaregeresa ekuchengetedza simba. Iyo yehupfumi modhi nekushandisazve simba seyakakosha inoda kuti munhu atarisire kuti mutengo uenderere mberi. Kudzika, imwe kudiwa kwekuteerera kune huwandu hwema core cycles, iyo yakati siyanei kubva kune yazvino simba density nzira yekuvandudza mota dzemagetsi dzakachena.
