Zvinoenderana nechimiro chemuviri R = U / I, mudziyo wekuyedza unobvumira iyo lithium bhatiri kumanikidza lithium bhatiri kumanikidza kuburikidza nehombe inogara DC ikozvino (ikozvino inoshandisa yakakura ikozvino ye40A kusvika 80A), kuyerwa panguva ino. Iyo voltage pane lithium bhatiri uye inoverengera ikozvino lithium bhatiri mune fomula. Kururama kweiyi nzira yekuyera yakakwirira uye inodzorwa.
Iko kuyerwa kwekukanganisa kukanganisa kunogona kudzorwa mukati me0.1%. Zvisinei, iyi nzira ine zvikanganiso zvakakura: (1) inogona kungoyera yakakura-yakawanda lithium bhatiri kana lithiamu bhatiri, diki-capacity lithium battery haigoni kutakurwa nehombe huru ye40A kusvika 80A mukati me2 kusvika ku3 seconds; (2) Kana bhatiri richipfuura yakakura ikozvino, electrode mukati me lithium bhatiri inokonzera polarization, zvichiita kuti polarized mukati kuramba.
Nokudaro, nguva yekuyera inofanira kunge ipfupi kwazvo, kana zvisina kudaro iyo yakayerwa yemukati yekupikisa kukosha yakakura; (3) yakakura ikozvino inopfuura nepakati pe lithium bhatiri ine kumwe kukuvadza kune electrodes mukati me lithium bhatiri. AC kudzvinyirirwa kudonhedza mukati mekudzivirira nzira inonyatso yakaenzana nekupikisa kunoshanda nekuti lithium bhatiri inonyatso yakaenzana neyakagadziriswa frequency uye yakagadziriswa ikozvino kune lithium bhatiri (ikozvino iri kushandisa 1 kHz frequency, 50mA diki ikozvino), uyezve samples yayo voltage Mushure mekugadzirisa. , yakasvibiswa, kukosha kwemukati kweti lithium bhatiri inotarirwa ne op amp circuit mushure mekutevedzana kwekugadzirisa, etc. Iyo lithium bhatiri yekuyera nguva ye AC pressure yakadonha mukati mekudzivirira nzira yakanyanyisa kupfupika, kazhinji mu 100 milliseconds.
Uku kurongeka kweiyi nzira yekuyera zvakare kwakanaka, uye chikanganiso chechiyero chinowanzova pakati pe1% kusvika 2%. Zvakanakira nekuipira kweiyi nzira: (1) Shandisa alternating yemukati kuramba kuyera nzira kuyera anenge ese mabhatiri e-lithium, kusanganisira mabhatiri madiki e-lithium. Notebook lithium bhatiri cell yemukati kuramba kazhinji nenzira iyi.
(2) Kuyera kwechiyero cheiyo AC kudonha kudonha kuyerwa nzira inogona kukanganiswa neiyo ripple ikozvino, uye pane zvakare zvinogoneka kuvhiringidza harmonic current. Uyu muedzo (3) chiyero (3) uchishandisa nzira iyi, iyo isina kukuvadza kwakanyanya kune lithium battery pachayo. (4) Kuyera kwechiyero cheiyo AC kudonha kudonha kuyerwa nzira haina kunaka seDC inoburitsa mukati meyero yekupikisa.
