5. Cycle Life(chikwata: nguva)& Kudzika kwekubuda, DoD
Kudzika kwekubuda: Inoratidza chikamu chekubuda kwebhatiri kune yakayerwa huwandu hwebhatiri. Shallow cycle mabhatiri haafanire kuburitsa anopfuura makumi maviri neshanu muzana ehukwanisiro hwavo, nepo yakadzika cycle mabhatiri anogona kuburitsa 80% yekugona kwavo. Bhatiri rinotanga kubuda pamhepo yekumusoro yevoltage uye rinomisa kuburitsa pane yakaderera muganhu voltage. Tsanangura mari yese yakabviswa se100%. Battery standard 80% DOD zvinoreva kuburitsa 80% yechaji. Semuenzaniso, kana yekutanga SOC iri 100% uye ndikaisa pa20% uye ndomira, ndiyo 80% DOD.
Upenyu hwebhatiri ye-lithium-ion huchaora zvishoma nezvishoma nekushandiswa uye kuchengetedza, uye zvichava pachena. Zvakadaro tora akangwara mafoni semuenzaniso, mushure mekushandisa foni kwenguva yakati, iwe unogona pachena kunzwa bhatiri refoni "risina kusimba", kutanga kunogona kungochaja kamwe chete pazuva, kumashure kungangoda kubhadharisa kaviri pazuva, izvo ndiwo mufananidzo wekuramba uchidzikira kwehupenyu hwebhatiri.
Lithium-ion bhatiri hupenyu hwakakamurwa kuita maviri paramita: kutenderera hupenyu uye hupenyu hwekarenda. Hupenyu hwekutenderera hunowanzoyerwa mumacycles, ayo anotaridza huwandu hwenguva iyo bhatiri rinogona kuchajwa nekuburitswa. Ehe, pane mamiriro pano, kazhinji mune yakanakira tembiricha uye humidity, ine yakatemerwa kuchaja uye yekuburitsa ikozvino yehudzamu hwekuchaja uye kubuda (80% DOD), verenga huwandu hwema cycles anowanikwa kana bhatiri radzikira kusvika makumi maviri muzana. yehuwandu hwakayerwa.
Tsanangudzo yehupenyu hwekarenda yakanyanya kuoma, bhatiri haigone kugara ichichaja uye ichiburitsa, pane chengetedzo uye masherufu, uye haigone kugara iri mumamiriro akakodzera ezvakatipoteredza, ichapfuura nemhando dzese tembiricha uye humidity. mamiriro, uye kuwanda kwehuwandu hwekuchaja nekuburitsa kuri kushandukawo nguva dzese, saka hupenyu chaihwo hwesevhisi hunoda kuedzerwa nekuedzwa. Zvichitaurwa zviri nyore, hupenyu hwekarenda inguva yenguva yekuti bhatiri isvike kumagumo ehupenyu mamiriro (semuenzaniso, kugona kunoderera kusvika 20%) mushure meimwe mamiriro ekushandisa pasi penzvimbo yekushandisa. Hupenyu hwekarenda hwakanyatsoenderana nezvinodiwa zvekushandisa, izvo zvinowanzoda kutsanangurwa kwemamiriro ekushandisa, mamiriro ekunze, nguva dzekuchengetedza, zvichingodaro.
6. MukatiRkusistance(chikwata: Ω)
Mukati Resistance: Inoreva kushorwa kwezvino inoyerera kuburikidza nebhatiri kana bhatiri iri kushanda, iyo inosanganisiraohmic yemukati kurambauyepolarization yemukati kuramba, uye polarization yemukati kushorwa kunosanganisiraelectrochemical polarization mukati kurambauyeconcentration yepolarization yemukati kuramba.
Ohmic kupikisa kwemukatiine electrode zvinhu, electrolyte, diaphragm kuramba uye kusangana nekupokana kwechikamu chimwe nechimwe.Polarization yemukati kurambainoreva kupokana kunokonzerwa nepolarization panguva ye electrochemical reaction, kusanganisira kuramba kunokonzerwa ne electrochemical polarization uye concentration polarization.
Chikamu chekupikisa kwemukati chinowanzonzi miliohm (mΩ). Mabhatiri ane hukuru hwekupikiswa kwemukati ane simba rekushandisa mukati uye kugadzirwa kwakakomba kwekupisa panguva yekuchaja uye kuburitsa, izvo zvinokonzeresa kuchembera nekukurumidza uye kuparara kwehupenyu hwemabhatiri e-lithium-ion, uye panguva imwe chete kudzikamisa kushandiswa kwekuchaja uye kuburitsa nechiyero chikuru chekuwedzera. . Nokudaro, kuduku kupikisa kwemukati ndiko, zviri nani hupenyu uye kuwedzera kwekuita kwe lithium-ion battery ichave.
