Chekutanga, iyo charge state (SOC) zvichireva kuti SOC is stateofcharge, zvinoreva mamiriro ekuchaja kwebhatiri. Kubva pamakona akasiyana semagetsi, simba, nezvimwewo, SOC ine zvakasiyana siyana zvinoreva.

Iyo SOC yeUS Advanced Battery Federation (USABC) yakashandiswa zvakanyanya, kureva reshiyo yechiyero chakayerwa pasi pesimba rasara uye mamiriro akafanana pane imwe chiyero chekuburitsa. Iyo inoenderana calculation formula ndeye: qm, iyo yakanyanya kuburitsa simba kana bhatiri raburitswa zvinoenderana neanogara aripo I; Q (in) iri muT nguva, bhatiri rinoburitsa bhatiri pasi pebhatiri pasi pebhatiri. Chechipiri, lithium-ion bhatiri yekuchaja mamiriro ekufanotaura nzira Iyo yekuchaja yelithium ion bhatiri ndeimwe yeakakosha paramita yebhatiri manejimendi system, asiwo hwaro hwekuchaja uye kubuda kwekutonga zano remota yese uye bhatiri basa rekuenzanisa.

Nekudaro, nekuda kwekuoma kweiyo lithium-ion bhatiri pachayo, iyo yakatsemuka haigone kuwanikwa nekuyerwa kwakananga, chete zvichienderana nehumwe hunhu hwekunze hwebhatiri, sekupikisa kwemukati kwebhatiri, iyo yakavhurika yedunhu voltage, tembiricha, ikozvino, nezvimwe. zvinoenderana parameters, uchishandisa zvinoenderana parameters. Characteristic curve kana formula yekuverenga yekupedzisa basa rekufanotaura pamamiriro ekuchaja.

Iyo yekuchaja mamiriro ekufungidzira yelithium-ion bhatiri haina-mutsara. Parizvino, iyo yakajairika nzira yakakosha kuburitsa kuyedza, kuvhurika redunhu voltage nzira, kuchengetedza nzvimbo, Kalman kusefa nzira, neural network nzira, nezvimwe. 1 Nheyo yekuburitsa muyedzo yekuburitsa kuyedza nzira ndeyekuita bhatiri munzvimbo isina kukanganiswa yekuburitsa panguva inogara iripo, kuverenga huwandu hwekubuda kana kubuda kwasvika pa cutoff voltage.
