QuantumScape yakapa yakasimba data data. Chaja 4 C, inomira 25 C, 0-> 80%. mumaminitsi gumi nemashanu

QuantumScape, yekutanga kugadzira masero e electrolyte akasimba, yakazvikudza pamusoro pemaparamita emasero ayo. Kugona kwavo kunoshamisa: vanobvumira kuchaja pa4 ° C, kutsungirira kusvika ku25 ° C, kupa simba remagetsi muhuwandu hwe0,3-0,4 kWh / kg uye kutenderera 1 kWh / l. JB Straubel, mubatsiri weTesla, anoona izvi sekubudirira.

QuantumScape yakave yakakurumbira kaviri munguva yakapfuura: kamwe, apo Volkswagen yakava mugoveri mukuru wekambani, uye kechipiri, apo JB Straubel, mubatsiri weTesla, akava nhengo yebhodhi revatungamiri. Ikozvino yava ruzha rwechitatu: kambani yakaburitsa mhedzisiro yekutsvagisa kwayo. Izvo zvinokatyamadza nekuda kwezvikonzero zvakati: sero rakajairwa saizi inoratidzwa iyo yakashanda pane yakajairika tembiricha (30 madhigirii celsius), uye mhedzisiro inoratidzwa kuti inogona kudhindwa.

Iyo QuantumScape Ceramic Cage iplate inoshanduka inenge saizi yekadhi rekutamba. Mukona yepamusoro yekurudyi, unogona kuona mutungamiri wekambani, Jagdeep Singh (c) QuantumScape.

Tiri kutaura nezvei? QuantumScape masero ari lithium masero anoshandisa yakasimba electrolyte panzvimbo yemvura electrolyte, pasina anode yakasiyana. Anode yavo ine lithium ions panguva yekuchaja (Li-metal). Kana sero richibudiswa, lithium ions inoenda kune cathode, anode inorega kuvapo.

Chimiro dhizaini yemazuva ano lithium-ion cell (kuruboshwe) uye QuantumScape sero. Musero rekirasi rinouya kubva kumusoro, isu tine electrode, graphite / silicon anode, porous membrane, lithium source cathode, uye electrode. Zvose izvi zvakanyudzwa mu electrolyte inofambisa kuyerera (c) yeQuantumScape ions.

Kuchaja pa4 C pasina derating

Kufambira mberi kwakakosha ndiko kugona kuchaja masero eQuantumScape kusvika ku4 ° C pasina kuvaparadza. Iko hakuna kukanganisa, sezvo ceramic electrolyte inobvumira kuyerera kwe lithium ions, asi haibvumiri lithium dendrites kukura. 4 C inoreva kuti ne60 kWh bhatiri tichasvika pakuchaja simba re240 kW, ne80 kWh yatova 320 kW, nezvimwe.. Panguva imwecheteyo, tichabhadhara kusvika ku80 muzana mumaminitsi gumi nemashanu, saka simba rekuchaja harizove rakanyanya kuderera kudarika kukwirira - richava 15 uye 192 kW, maererano.

Masimba akadai anozoshanduka kuita kuzadzazve renji nekumhanya kwe +1 200 km / h, i.e. +20 km / min... Kumira kwemaminetsi gumi nemashanu kuti utambanudze mapfupa ako uye chimbuzi zvinokupa makiromita anosvika mazana matatu kana anopfuura makiromita mazana maviri enzira yemahara.

Iko mukana weiyo yakakosha "customization" yemasero inonakidza zvakare. Iyo kambani yakazvikudza bvunzo dzinosvika 25 C. Tichifunga kuti tichange tichishandisa "chete" 20 C, mota ine 60 kWh bhatiri inokwanisa kumira 1,2 MW shots!

Pamusoro pe800 yebasa kutenderera ne ~ 10% kudzikisira

Imwe mukana mukuru weQuantumScape masero ndeyekukwira kwavo bhasikoro. Ivo vanosvika nyore nyore kunofungidzirwa 800 cycles (basa = full charge and discharge) pa1 ° C uye vanovimbisa kutowedzera kusimba pamagetsi mashoma - uye iyo yekupedzisira inogona kuwanikwa mumotokari dzemagetsi.

Zvinogona kuita sekuti 800 duty cycles haisi yakawanda, asi kana tikaisa kukosha uku pamushini, tinowana nhamba huru. Ngatitii tine masero eQuantumScape akaunganidzwa mubhatiri re60 kWh. Kugona uku kunoita kuti ukwanise kutyaira zviri nyore kupfuura makiromita 300. 800 kutenderera kwebasa iri mileage yeanenge 240 zviuru zvemakiromita (dhayagiramu pamusoro).

Ne mileage yakadaro, zvinhu zvinoramba zvichichengetedza 90 muzana yehuwandu hwazvo, saka zvinokutendera kuti utyaire makiromita anopfuura 300, asi makiromita 300 chete pasina kubhadharisa! Kana kuderedzwa kwemutsara kuchienderera mberi, izvo zvatisati taziva nezvazvo, pa480 80 makiromita tichasvika panosvika XNUMX muzana yesimba uye zvichingodaro.

Isu tinowedzera kuti nhasi chiratidzo chekutsiva kana kugadzirisa bhatiri isimba rinosvika 65-70 muzana yesimba rekutanga.

Mushure mezvose, zvinongedzo kune ndege?

JB Straubel, mubatanidzwa waTesla uye iye zvino ari nhengo yeQuantumScape board of directors, anoona kubudirira kwekambani sekubudirira.... Anosimbisa kuti kuwedzera kwesimba kwakangoerekana kwaitika hakuna kunyanya kuwanda, uye Tesla akayera kufambira mberi muzvikamu zvedijiti imwe chete mumakore apfuura. Mharidzo kubva kune dzimwe kutanga dzinowanzo tarisa pane dzakasarudzwa paramita uye dzakasiya vamwe, nepo QuantumScape yairatidza huwandu hwezviyero zvine chekuita nekusimba uye mutoro uye kutsungirira.

Mukuona kwake, zvinhu zvitsva zvinogona kubvumira kusikwa kwendege yemagetsi ine mitsara yatinoziva.

Hapana kana mumwe wemifananidzo anoratidza akachajwa QuantumScape maseru. Tichitarisa neanimation, dzakazvimba zvakanyanya. Musiyano unoratidzika kunge une 2-3 nguva yakakura kupfuura iyo yelithium-ion masero ane graphite-based anodes, iyo inogona kuve inogumira pakugadzira mabhatiri epamusoro.
