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. Noma kunjalo thatha amafoni ahlakaniphile njengesibonelo, ngemva kokusebenzisa ifoni isikhathi esithile, ungakwazi ngokusobala ukuzwa ibhethri yefoni "engahlali isikhathi eside", isiqalo singashaja kanye ngosuku, ngemuva kungase kudingeke ukuthi ukushaja kabili ngosuku, okuwumfanekiso wokwehla okuqhubekayo empilweni 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, neshaji elinganiselwe kanye namandla okukhipha ekujuleni kweshaja nokukhipha (80% DOD), abale inani lemijikelezo etholwayo lapho umthamo webhethri wehla ufike ku-20% womthamo olinganiselwe.
Incazelo yempilo yekhalenda iyinkimbinkimbi kakhulu, ibhethri alikwazi ukushaja nokushajwa ngaso sonke isikhathi, kunesitoreji namashalofu, futhi ayikwazi ukuhlala isesimweni esikahle semvelo, izodlula kuzo zonke izinhlobo zezimo zokushisa nokuswakama, futhi izinga lokuphindaphinda lokushaja nokukhipha amandla 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 anokusetshenziswa okuphezulu kwamandla angaphakathi kanye nokukhiqiza ukushisa okungathi sína phakathi nokushaja nokukhipha, okuzobangela ukuguga okusheshayo kanye nokonakaliswa kwesikhathi sokuphila kwamabhethri e-lithium-ion, futhi ngesikhathi esifanayo kukhawulele ukusetshenziswa kokushaja nokushajwa ngezinga elikhulu lokuphindaphinda. Ngakho-ke, okuncane ukumelana kwangaphakathi, impilo engcono nokusebenza kokuphindaphinda kwebhethri ye-lithium-ion kuyoba ngcono.
