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 pamagetsi epamusoro 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. Zvichakadaro tora akangwara mafoni semuenzaniso, mushure mekushandisa foni kwenguva yakati, iwe unogona zviri pachena kunzwa bhatiri refoni "risina kusimba", kutanga kunogona kungochaja kamwe chete pazuva, kumashure kungada kubhadharisa kaviri pazuva, inova iyo inofananidzira kuderera kunoramba kuripo muhupenyu hwebhatiri.
Lithium-ion bhatiri hupenyu hwakakamurwa kuita maviri paramita: kutenderera hupenyu uye hupenyu hwekarenda. Hupenyu hwema cycles 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 kuburitsa (80% DOD), verenga huwandu hwematenderedzwa akaitika kana bhatiri radzikira kusvika 20% yechiyero chakayerwa.
Tsanangudzo yehupenyu hwekarenda yakanyanya kuomarara, bhatiri haigone kugara ichichaja nekuburitsa, pane chengetedzo nesherufu, uye haigone kugara iri munzvimbo yakakodzera yezvakatipoteredza, ichapfuura nemhando dzese dzekushisa uye hunyoro mamiriro, uye kuwanda kwehuwandu hwekuchaja nekuburitsa kuri kuchinjawo nguva dzese, saka hupenyu chaihwo hwesevhisi hunoda kuteedzerwa 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 kushorwa, uye polarization yemukati kushorwa kunosanganisiraelectrochemical polarization mukati kurambauyeconcentration polarization internal resistance.
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 chinowanzoita miliohm (mΩ). Mabhatiri ane hukuru hwekupikiswa kwemukati ane simba rekushandisa mukati uye chizvarwa chakakomba chekupisa 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.
