Chakavanzika chehupenyu hurefu hwemabhatiri anochajwa chinogona kunge chiri mukumbundikira mutsauko.New modelling yekuti lithium-ion masero ari mupakeji anoshatisa anoratidza nzira yekuchajisa kune yega yega sero kuti mabhatiri eEV agone kubata machaji akawanda uye kudzivirira kutadza.

Tsvakurudzo, yakaburitswa Mbudzi 5 mukatiIEEE Transactions paKudzora Systems Technology, inoratidza kushingairira kutonga huwandu hwemagetsi arikuyerera kune yega yega sero mupakiti, pane kuunza kuchaja zvakafanana, kunogona kuderedza kusakara uye kubvaruka.Iyo nzira inobudirira inobvumira sero rega rega kuti rirarame zvakanakisa - uye kureba - hupenyu.

Sekureva kwaStanford purofesa uye munyori wechidzidzo chepamusoro Simona Onori, ekutanga simulations anoratidza mabhatiri anofambiswa nehunyanzvi tekinoroji anogona kubata anosvika makumi maviri muzana ekuwedzera machaji ekuchaja, kunyangwe nekugara uchichaja, izvo zvinowedzera kunetsa pabhatiri.

Kuedza kwakawanda kwekare kwekuwedzera hupenyu hwebhatiri remotokari yemagetsi kwakanangana nekuvandudza dhizaini, zvigadzirwa, uye kugadzirwa kwesero rimwe chete, zvichibva pane fungidziro yekuti, senge zvinongedzo mumaketani, bhatiri paki rinongonaka sesero rayo risina kusimba.Chidzidzo chitsva ichi chinotanga nekunzwisisa kuti kunyangwe zvisina kusimba zvinongedzo zvisingadzivisike - nekuda kwekugadzira kusakwana uye nekuti mamwe maseru anodzikira nekukurumidza kupfuura mamwe sezvaanoratidzirwa kune zvinonetsa sekupisa - haafanire kudzikisa pasi rese paki.Chinokosha ndechekugadzirisa mitengo yekuchaja kune yakasarudzika kugona kwesero rega rega kudzivirira kutadza.

"Kana ikasabatwa nemazvo, sero-kune-sero heterogeneity inogona kukanganisa hupenyu hurefu, hutano, uye kuchengetedzeka kwebhatiri pack uye kuita kuti bhatiri ritange kusashanda," akadaro Onori, anove mutevedzeri wepurofesa wesimba resainzi engineering kuStanford Doerr. Chikoro cheSustainability."Maitiro edu anoenzanisa simba riri musero rega rega mupakeji, achiunza maseru ese kunzvimbo yekupedzisira yakanangwa yekuchaja zvine mwero uye nekuvandudza hupenyu hurefu hwepakeji."

Yakafemerwa kugadzira bhatiri remamirioni

Chikamu chekukurudzira kwetsvagiridzo kutsva chinodzokera kuchiziviso cha2020 naTesla, kambani yemotokari dzemagetsi, yebasa pa "bhatiri remirioni".Iri ringave bhatiri rinokwanisa kugonesa mota 1 miriyoni mamaira kana kupfuura (nekuchaja nguva dzose) isati yasvika padanho apo, sebhatiri re lithium-ion mufoni yekare kana laptop, bhatiri reEV rinobata chaji shoma kuti ishande. .

Bhatiri rakadaro raizopfuura automaker 'yakajairika waranti yemabhatiri emotokari yemagetsi emakore masere kana 100,000 mamaira.Kunyangwe mabhatiri emapakiti achigara achipfuura waranti yavo, kuvimba kwevatengi mumotokari dzemagetsi kunogona kusimbiswa kana inodhura bhatiri pack inotsiva ikave kushoma.Bhatiri rinogona kuramba rakachajiswa mushure mezviuru zvekuchaja zvakare rinogona kurerutsa nzira yekuiswa kwemagetsi emarori akareba, uye kutorwa kwezvinonzi mota-kune-grid masisitimu, umo mabhatiri eEV aizochengeta uye kutumira simba rinodzokororwa kune. iyo grid yemagetsi.

"Zvakazotsanangurwa gare gare kuti iyo miriyoni-mamaira bhatiri pfungwa yaisava chaiyo chemistry nyowani, asi ingori nzira yekushandisa bhatiri nekusaita kuti ishandise yakazara chaji renji," Onori akadaro.Tsvagiridzo inoenderana yakanangana nesero lithium-ion maseru, ayo kazhinji asingarasikirwe nekuchaja nekukurumidza sezvinoita akazara bhatiri mapaketi.

Ashamiswa, Onori nevatsvagiri vaviri mulabhu yake - nyanzvi yemashure Vahid Azimi uye mudzidzi wePhD Anirudh Allam - vakafunga kuongorora kuti manejimendi emhando dzebhatiri aripo angavandudza sei kushanda uye hupenyu hwesevhisi yebhatiri rakazara pack, iro rinogona kunge riine mazana kana zviuru zvemasero. .

A high-fidelity bhatiri modhi

Sekutanga nhanho, vatsvakurudzi vakagadzira chimiro chepamusoro-soro chekombiyuta yehutano hwebheteri iyo yakanyatsomiririra kuchinja kwemuviri nemakemikari kunoitika mukati mebhatiri munguva yehupenyu hwayo hwekushanda.Dzimwe shanduko idzi dzinoitika mumasekondi kana maminetsi - dzimwe nemwedzi kana makore.

"Kune zvatinoziva, hapana chidzidzo chekare chakashandisa rudzi rwemhando yepamusoro-soro, yakawanda-nguva yakawanda yebheteri yatakagadzira," akadaro Onori, uyo ari mutungamiriri weStanford Energy Control Lab.

Kumhanya kuenzanisa nemuenzaniso kwakaratidza kuti bhatiri paki yemazuva ano inogona kugadziridzwa uye kudzorwa nekumbundira misiyano pakati pemaseru ayo.Onori nevamwe vaanoshanda navo vanofungidzira modhi yavo ichishandiswa kutungamira kuvandudzwa kwemabhatiri manejimendi masisitimu mumakore anouya ayo anogona kuiswa zviri nyore mumagadzirirwo emotokari aripo.

Haisi chete mota dzemagetsi dzinomira kuti dzibatsirwe.Anenge chero application iyo "inosimbisa bhatiri pack zvakanyanya" inogona kuve mumiriri akanaka wekutonga kuri nani anoziviswa nemhedzisiro mitsva, Onori akadaro.Mumwe muenzaniso?Ndege yakaita seDrone ine magetsi akatwasuka uye kumhara, dzimwe nguva inodaidzwa kuti eVTOL, iyo vamwe vemabhizinesi vanotarisira kushanda sematekisi emhepo uye kupa mamwe masevhisi ekufambisa kwemhepo mumadhorobha mumakore gumi anotevera.Zvakadaro, zvimwe zvikumbiro zvemabhatiri e-lithium-ion anogona kucheneswa, kusanganisira kubhururuka nendege uye kuchengetwa kwakakura kwesimba rinogonekazve.

"Lithium-ion mabhatiri akatochinja nyika nenzira dzakawanda," akadaro Onori."Zvakakosha kuti tiwane zvakawanda sezvatinogona kubva mune ino shanduko tekinoroji nevatevedzeri vayo vachauya."
