Fungidzira munhu wepfungwa achiudza vabereki vako, pazuva rawakazvarwa, kuti waizorarama kwenguva yakareba sei.Chiitiko chakafanana chinogoneka kune vezvemakemikari ebhatiri vari kushandisa mhando nyowani dzemakomputa kuverengera hupenyu hwebhatiri zvichibva pane zvishoma sedenderedzwa rimwechete re data rekuedzwa.

Muchidzidzo chitsva, vaongorori veDhipatimendi reMagetsi reUS (DOE) Argonne National Laboratory vakatendeukira kusimba rekudzidza kwemuchina kufanotaura nguva yehupenyu hweakasiyana siyana emakemikari ebhatiri.Nekushandisa data rekuyedza rakaunganidzwa kuArgonne kubva kune seti yemabhatiri mazana matatu anomiririra matanhatu akasiyana makemikari makemikari, masayendisiti anogona kunyatsoona kuti mabhatiri akasiyana acharamba achitenderera kwenguva yakareba sei.

Mune muchina wekudzidza algorithm, masayendisiti anodzidzisa chirongwa chekombuta kuita fungidziro pane yekutanga seti yedata, uye wozotora zvayakadzidza kubva pakudzidziswa ikoko kuita sarudzo pane imwe seti yedata.

"Kune marudzi ese akasiyana ekushandisa bhatiri, kubva kunharembozha kuenda kumotokari dzemagetsi kusvika kugedhi yekuchengetedza, hupenyu hwebhatiri hwakakosha kune wese mutengi," akadaro Argonne computational sainzi Noah Paulson, munyori wechidzidzo ichi.“Kuchovha bhatiri kane zviuru kusvikira rakundikana kunogona kutora makore;nzira yedu inogadzira mhando yekicheni yekuyedza kicheni kwatinogona kukurumidza kuona kuti mabhatiri achaita sei. "

"Parizvino, nzira chete yekuongorora kuti huwandu hwebhatiri hunopera sei ndeyekutenderera bhatiri," akawedzera Argonne electrochemist Susan "Sue" Babinec, mumwe munyori wechidzidzo ichi."Inodhura zvakanyanya uye inotora nguva yakareba."

Sekureva kwaPaulson, maitiro ekumisikidza bhatiri hupenyu hunogona kuve hunyengeri."Chokwadi ndechekuti mabhatiri haagari nekusingaperi, uye kuti anogara kwenguva yakareba sei zvinoenderana nemashandisiro atinoashandisa, pamwe nekugadzirwa kwawo uye chemistry," akadaro.“Kusvika zvino, pasati pave neimwe nzira yakanaka yekuziva kuti bhatiri richagara kwenguva yakareba sei.Vanhu vachada kuziva kuti vane nguva yakareba sei kusvika vazoshandisa mari pabhatiri idzva. "

Imwe yakasarudzika yechidzidzo ndechekuti yaivimba nebasa rakakura rekuyedza rakaitwa kuArgonne pane zvakasiyana siyana zvebhatiri cathode zvinhu, kunyanya Argonne's patented nickel-manganese-cobalt (NMC)-based cathode."Taive nemabhatiri aimiririra makemikari akasiyana, ane nzira dzakasiyana dzekudzikisira nekutadza," akadaro Paulson."Kukosha kwechidzidzo ichi ndechekuti yakatipa masaini anotaridza mabatiro anoita mabhatiri."

Kuwedzera kudzidza munzvimbo ino kune mukana wekutungamira ramangwana remabhatiri e-lithium-ion, akadaro Paulson."Chimwe chezvinhu zvatinokwanisa kuita kudzidzisa algorithm pane inozivikanwa chemistry uye kuti iite kufanotaura pane isingazivikanwe chemistry," akadaro."Chaizvoizvo, iyo algorithm inogona kutiratidza nzira yemakemikari matsva uye akavandudzwa anopa hupenyu hurefu."

Nenzira iyi, Paulson anotenda kuti muchina wekudzidza algorithm unogona kukurumidza kusimudzira uye kuyedzwa kwezvinhu zvebhatiri.“Iti une chinyorwa chitsva, uye unochitenderedza kakati wandei.Unogona kushandisa algorithm yedu kufanotaura hurefu hwayo, wobva waita sarudzo dzekuti unoda kuramba uchiitenderedza uchiyedza here kana kuti kwete. "

"Kana iwe uri muongorori murabhoritari, unogona kuwana uye kuyedza zvimwe zvinhu zvakawanda munguva pfupi nekuti une nzira inokurumidza yekuzviongorora," Babinec akawedzera.

Pepa rakavakirwa pachidzidzo, "Feature engineering yekudzidza muchina yakagonesa kufanotaura kwekutanga kwehupenyu hwebhatiri,” yakabuda muKukadzi 25 online edition yeJournal of Power Sources.

Pamusoro paPaulson naBabinec, vamwe vanyori vepepa vanosanganisira Argonne's Joseph Kubal, Logan Ward, Saurabh Saxena naWenquan Lu.

Chidzidzo ichi chakatsigirwa nemari yeArgonne Laboratory-Yakanangana neKutsvagisa neKuvandudza (LDRD) rubatsiro.
