5. Ukuphila Komjikelezo(iyunithi: izikhathi)& Ukujula kokukhishwa, i-DoD
Ukujula kokukhishwa: Ibonisa iphesenti lokuphuma kwebhethri kumthamo olinganiselwe webhethri. Amabhethri omjikelezo ongashoni akumele akhiphe ngaphezu kuka-25% womthamo wawo, kuyilapho amabhethri omjikelezo ojulile angakhipha u-80% womthamo wawo. Ibhethri iqala ukushajwa ngevolumu ephezulu yomkhawulo futhi inqamule ukushajwa ngevolthi yomkhawulo ephansi. Chaza zonke izindleko ezikhishiwe njengo-100%. Izinga lebhethri elingu-80% DOD lisho ukukhipha u-80% wenkokhiso. Isibonelo, uma i-SOC yokuqala ingu-100% futhi ngiyibeke ku-20% bese ngiyeka, lokho kungu-80% DOD.
Impilo yebhethri ye-lithium-ion izobola kancane kancane ngokusetshenziswa nokugcinwa, futhi kuzoba sobala kakhulu. Namanje thatha amafoni smart njengesibonelo, ngemva kokusebenzisa ifoni isikhathi esithile, ungakwazi ngokusobala uzizwe ibhethri yefoni "ayihlala isikhathi eside", isiqalo kungase kuphela ukushaja kanye ngosuku, ngemuva kungase kudingeke ukushaja kabili ngosuku, okuyinto kuwukubonakaliswa kokwehla okuqhubekayo kwempilo yebhethri.
Impilo yebhethri ye-lithium-ion ihlukaniswe ngamapharamitha amabili: impilo yomjikelezo nempilo yekhalenda. Impilo yomjikelezo ngokuvamile ikalwa ngemijikelezo, ebonisa inani lezikhathi lapho ibhethri lingashajwa khona futhi lishajwe. Yiqiniso, kunezimo lapha, ngokuvamile ezingeni lokushisa elifanele kanye nomswakama, nenani elilinganiselwe lokushaja kanye nokukhishwa kwamandla okujula kweshaja nokukhipha (80% DOD), ukubala inani lemijikelezo eyenzeka lapho amandla ebhethri ehla aze afike ku-20% umthamo olinganiselwe.
Incazelo yempilo yekhalenda iyinkimbinkimbi kakhulu, ibhethri alikwazi ukushaja nokukhipha amandla njalo, kunesitoreji namashelufu, futhi alikwazi ukuhlala lisesimweni esikahle semvelo, lizodlula kuzo zonke izinhlobo zezinga lokushisa nomswakama. izimo, kanye nezinga lokuphindaphinda lokushaja nokukhulula nalo liyashintsha ngaso sonke isikhathi, ngakho-ke impilo yesevisi yangempela idinga ukulingiswa futhi ihlolwe. Kalula nje, impilo yekhalenda ubude besikhathi ukuze ibhethri lifinyelele esimweni sokuphela kwempilo (isb., umthamo wehla ube ngu-20%) ngemva kwesimo esithile sokusebenzisa ngaphansi kwendawo yokusebenzisa. Impilo yekhalenda ihambisana eduze nezimfuneko ezithile zokusetshenziswa, ngokuvamile ezidinga ukucaciswa kwezimo ezithile zokusetshenziswa, izimo zemvelo, izikhawu zokulondoloza, nokunye.
6. NgaphakathiRukuphikisa(iyunithi: Ω)
Ukumelana Kwangaphakathi: Kubhekisela ekuphikisweni kwamanje okugeleza ebhethri lapho ibhethri isebenza, okuhlanganisaukumelana kwangaphakathi kwe-ohmicfuthii-polarization ukumelana kwangaphakathi, kanye ne-polarization ukumelana kwangaphakathi kuhlanganisaelectrochemical polarization ukumelana kwangaphakathifuthiukuhlushwa kwe-polarization ukumelana kwangaphakathi.
Ukumelana kwangaphakathi kwe-Ohmiciqukethe izinto ze-electrode, i-electrolyte, ukumelana ne-diaphragm kanye nokumelana nokuxhumana kwengxenye ngayinye.Ukumelana ne-polarization yangaphakathiibhekisela ekuphikiseni okubangelwa i-polarization ngesikhathi sokusabela kwe-electrochemical, okuhlanganisa ukumelana okubangelwa i-electrochemical polarization kanye ne-concentration polarization.
Iyunithi yokumelana kwangaphakathi ngokuvamile i-miliohm (mΩ). Amabhethri anokumelana okukhulu kwangaphakathi asebenzisa amandla aphezulu angaphakathi kanye nokukhiqiza ukushisa okungathi sína phakathi nokushaja nokukhipha, okuzobangela ukuguga okusheshayo nokonakaliswa kwesikhathi sokuphila kwamabhethri e-lithium-ion, futhi ngesikhathi esifanayo kukhawule ukusetshenziswa kokushaja nokushajwa ngezinga elikhulu lokuphindaphinda. . Ngakho-ke, okuncane ukumelana kwangaphakathi, impilo engcono nokusebenza kokuphindaphinda kwebhethri ye-lithium-ion kuyoba ngcono.
