Sei Tesla achiomerera pakushandisa cobalt lithium?

Bhatiri raTesla chimwe chezvinhu zvakakosha zvemotokari dzemagetsi. Zvainyombwa nokuzvidzwa pamazuva ekutanga. Kunyangwe mushure mekunge zvikamu zvinoputika zvatengeswa, nyanzvi dzakawanda dzeindasitiri dzakadana tekinoroji yebhatiri yechinyakare ine zvinangwa zvisina kujeka. Izvi zvinodaro nekuti Tesla ndiyo yega kambani inoshandisa 18650 lithium-cobalt-ion mabhatiri, ayo anowanzo shandiswa mumakomputa emabhuku uye haana kunaka semota dzemagetsi uye anoisa njodzi yekuchengetedza. ichokwadi here?

Maererano neshumo, kukanganisa kwemabhatiri pamotokari dzemagetsi kunooneka maererano nemagetsi ekubuda. Iron phosphate parizvino ndiyo yekutanga sarudzo mumusika, senge Chevrolet Volt, Nissan Leaf, BYD E6 uye FiskerKarma, nekuda kwekuvimbika kwavo, kuchengetedzwa uye nguva yekuchaja.

Tesla ndiyo mota yekutanga kushandisa lithium cobalt ion mabhatiri

Tesla’s mota dzemitambo uye modhi dzinofambiswa ne18650 lithium cobalt oxide mabhatiri. Kana ichienzaniswa nemabhatiri e-lithium iron phosphate, bhatiri iri rine maitiro akaomarara, simba rakawanda, simba rakawanda, uye kukwirira kwaro, asi rine chengetedzo yakaderera, hunhu husina kunaka hwethermoelectric, uye mutengo wakanyanya.

Sekureva kwevari mukati meindasitiri, voltage inogara yakadzikira pane 2.7V kana yakakwira kupfuura 3.3V, uye zviratidzo zvekupisa zvichaonekwa. Kana bhatiri paki yakakura uye tembiricha gradient isina kudzorwa zvakanaka, pane njodzi yemoto. Hazvishamisi kuti Tesla akashoropodzwa nekuda kwekusavimbika muhunyanzvi hwebhatiri, nekuti tekinoroji yebhatiri inonyanya kutarisisa pane voltage, ikozvino, uye kudzora kwemafuta.

Zvisinei, mukuita, lithium-ion iron phosphate mabhatiri anonzi akachengeteka uye akavimbika, asi haasi nguva dzose aripo. Mukugadzirisa maitiro, iron oxide inogona kudzikiswa kuita elemental iron pakupisa kwakanyanya. Simbi yakareruka inokonzeresa diki diki rebhatiri, iro rinopesana. Pamusoro pezvo, mukuita, mabhatiri ekuchaja uye ekuburitsa mabhatiri e-lithium iron phosphate akasiyana, kusimba kwakashata, uye kuwanda kwesimba kwakadzikira, izvo zvinokanganisa zvakananga hupenyu hwebhatiri hwemotokari dzemagetsi. Sekureva kwetsvakiridzo yechangobva kuitika yeHaitong International Securities, kuwanda kwesimba kwemabhatiri eTesla (170Wh/kg) kunoda kusvika zvakapetwa kaviri kune mabhatiri eBYD’s lithium-ion iron phosphate.

Amai Whittingham vekuHuntington University kuUnited Kingdom vakagadzira 18650 mabhatiri elaptops, tochi nemimwe michina yedhijitari kare kuma1970, asi Tesla ndiyo yaive kambani yekutanga kushandisa 18mm muhupamhi uye 65mm mukukwirira mumotokari. Cylindrical lithium bhatiri kambani.

Tesla’s director webhatiri tekinoroji, Kirt Kady, akataura mubvunzurudzo yapfuura kuti Tesla akaedzawo mazana matatu emhando dzakasiyana dzebhatiri pamusika, kusanganisira mabhatiri akadzikama uye mabhatiri mativi, asi akasarudza Panasonic’s 300. Kune rumwe rutivi, 18650 ine yakakwirira simba density, yakanyatsogadzikana uye inowirirana. Kune rimwe divi, 18650 inogona kushandiswa kuderedza mutengo wemabhatiri masisitimu. Mukuwedzera, kunyange zvazvo muyero webhatiri rimwe nerimwe uri muduku zvikuru, simba rebhatiri rimwe nerimwe rinogona kudzorwa mukati mechikamu chiduku. Kunyangwe kana paine chakakanganisika mubhatiri pack, kukanganisa kwechirema kunogona kuderedzwa kana kuchienzaniswa nekushandisa yakakura chiyero bhatiri. Pamusoro pezvo, China inogadzira mabhatiri 18650 gore rega rega, uye mwero wekuchengetedza uri nani.

Lithium bhatiri NCR18650 bhatiri repamusoro-soro rine simba rezita re 3.6V, zvishoma zvishoma zvinokwana 2750 mA, uye chikamu chechikamu che 45.5g. Pamusoro pezvo, iyo simba density ye18650 yakashandiswa muTesla yechipiri-chizvarwa MODEL S ndeye 30% yakakwirira kupfuura iyo yapfuura mota yemitambo.

Tesla Chief Technology Officer JBStraubel akataura kuti kubvira pakatangwa mota yeModel S, mutengo webhatiri wakadzikira neanenge 44% uye ucharamba uchidonha. Muna 2010, Panasonic yakapa madhora mamirioni makumi matatu kuTesla semugovani. Muna 30, mapato maviri aya akawana chibvumirano chekupa mabhatiri emotokari dzese dzeTesla mumakore mashanu anotevera. Tesla parizvino anofungidzira kuti Panasonic 2011 ichaiswa mumhando dze18650.

6831 lithium mabhatiri akagadziridzwa zvinoshamisa

Tesla inogadzirisa sei iyo 18650 njodzi yekuchengetedza? Chombo chayo chakavanzika chiri mubhatiri rekugadzirisa system, iyo inopa mhinduro yekubatanidza 68312 amp Panasonic 18650 mabhatiri akaiswa munhevedzano uye nenzira yakafanana.

Motokari yemagetsi inoda 18,650 mabhatiri. Iyo bhatiri system yeTesla Roadster ine 6,831 madiki mabhatiri maseru, uye iyo Model s ine akawanda se8,000 bhatiri maseru. Nzira yekuisa uye kuunganidza idzi nhamba huru dzemabhatiri maduku inonyanya kukosha.
