Saka, hondo! Tesla: cylindrical elements chete, 4680. Volkswagen: yunifomu rectangular elements

Munguva yeBattery Day muna Gumiguru 2020, Tesla akazivisa kusikwa kweiyo cylindrical cell fomati, iyo 4680, iyo ichakurumidza kuoneka mumutsara wemotokari. Mwedzi mitanhatu gare gare, Volkswagen yakazivisa yakajairwa cuboid link inozova hwaro hwerinenge boka rose, kusanganisira marori.

Volkswagen iri kubata, ichigadzira slip yemakore 2-3 chete ichienzaniswa neTesla

Tafura yezvinyorwa

• Volkswagen iri kubata, ichigadzira slip yemakore 2-3 chete ichienzaniswa neTesla
  • Zvose izvi zvinorevei kune vateereri vepakati?

Kune marudzi matatu emasero parizvino ari kushandiswa mumotokari dzemagetsi:

• cylindrical (cylindrical shape) inonyanya kushandiswa naTesla,
• rexangular (Chirungu prismatic), zvichida yakajairika pakati pechinyakare vagadziri, akasarudza kuzviita Concern Volkswagen mukati me "single cell",
• sachet (homwe), iyo inooneka panonyanya kukosha ndeye "kusvina kunze" yakawanda bhatiri remukati sezvinobvira kubva kune yakapihwa huwandu.

Imwe neimwe yemhando idzi ine zvakanakira nezvayakaipira: cylindrical aimbove ainyanya kufarirwa (akashandiswa mumakamera nemalaptops), saka Tesla naPanasonic vakanyanya mazviri. Vanovimbisawo kuchengetedzwa kwepamusoro. Sachet vanobvumira kuwanda kwesimba rakakwirira kuti riwanikwe, asi vagadziri vanofanira kuyeuka kuti vanogona kuwedzera zvakanyanya vhoriyamu sezvo vasina mavhuriro ekuburitsa chero angangoita magasi. Cuboids izvi ndizvo zviri mukati memabhegi mune yakaoma kesi, nzira iri nyore yekuvaunganidza (somuenzaniso, kubva pamatombo) ibheti yakagadzirira, uyezve, ivo vane mechanically simba.

Volkswagen inotoshandisa maseru rectangular, asi zvinoita sekunge chimiro chavo chinenge chakagadziridzwa kune dhizaini yemotokari. Masero akabatana vanofanirwa kuoneka kekutanga muna 2023, uye muna 2030 vanofanirwa kuverengera kusvika makumi masere muzana emaseru akashandiswa:

Masero matsva haarongedzwe kuita mamodule (kubva pasero kuenda pakurongedza), uye iyo yakafanana fomati (fomu) inofanirwa kuve nemhando dzakasiyana dzemakemikari mukati:

• mumotokari dzakachipa vachazviita LFP masero (lithium iron phosphate)
• nezvinhu zvakawanda ichashanda masero ane manganese akawanda (uye imwe nickel)
• pamamodheru akasarudzwa inooneka NMC masero (nickel-manganese-cobalt cathodes),
• ... uye kuwedzera kwavari, Volkswagen inoyeukawo masero e electrolyte akasimba, sezvo iine 25% yezvikamu zveQuantumScape. Solid-state maseru anotobvumira kuwedzera kwe30% muhuwandu uye kubhadharisa mumaminitsi gumi nemaviri pachinzvimbo chemakumi maviri (data rakavakirwa prototypes):

Kana iri anode, kambani haiite chero fungidziro, asi nhasi iri kuyedza graphite nesilicon. Zvino kuda kuziva: Porsche Taycan uye Audi e-tron GT vane silicon anodekuvonga kwavanogona kubhadhariswa nesimba rakadaro (ikozvino: kusvika 270 kW).

Pakupedzisira Volkswagen inoda kushandisa zvinongedzo sezvimiro zvemota (sero kumuchina) uye zvinoita sekunge maseru akajairwa anozogadziriswa izvozvo. Zvakadaro, Boka risati rasvika pachinhanho ichi, rinofanirwa kupfuura nedanho iri. bhatiri risina mamodule (sero-ku-pack) - muchina wekutanga wakavakwa nenzira iyi uchave modhi yakagadzirwa neiyo Artemis Audi chirongwa... Zvinogoneka kuti isu tichaona conceptual vhezheni yemota iyi yatove muna 2021.

Modular bhatiri. Skeleton yake inobatanidza. Nhanho inotevera ndeye zvinongedzo zvisiri ballast, asi chimiro chemota - Volkswagen cell-to-mota (c)

Zvinhu zvitsva zvinogona kugadzirwa mumafekitori matanhatu ayo Volkswagen inoda kuvhura panosvika 6. (vamwe nevadyidzani). Yekutanga yakavakwa neNorthvolt ichavakwa muSkelleftea, Sweden. Yechipiri iri muSalzgitter (Germany, kubvira 2025). Yechitatu ichave muSpain, Portugal kana France (kubva 2026). Muna 2027, chirimwa muEastern Europe chinofanira kutangwa, kusanganisira Poland., Czech Republic neSlovakia zvakabvuma - hapana sarudzo parizvino. Hazvizivikanwe zvakare kuti zvirimwa zviviri zvekupedzisira zvichavakwa kupi.

Zvose izvi zvinorevei kune vateereri vepakati?

Kubva pamaonero edu kukosha kwakakosha kwemasero akabatana ndiko kudzikiswa kwemitengo yekugadzira... Sezvo zvichange zviri zvepasirese, otomatiki akagadziridzwa nenzira imwechete achakwanisa kushanda pazvirimwa zvese zvinonetsa. Imwe tsvakurudzo rabhoritari inokwana imwe mhando kemisitiri. Ndizvo zvose pamwe kuendesa kumitengo yakaderera yemotokari dzemagetsi.

Uye kunyange kana izvozvo zvikasaitika, Tesla, Volkswagen, Audi uye Skoda inogona kuisa mutengo pamusika wese. Nekuti kushandisa vatengesi vekunze (ona Hyundai, BMW, Daimler,…) nguva dzose zvinoreva kushomeka kuchinjika uye mutengo wakakwira.
