Ezezimotoamabhethri e-lithium amandlasiguqule indlela esicabanga ngayo ngezokuthutha.Sezidume kakhulu ngenxa yokuminyana kwazo okuphezulu, ukuphila isikhathi eside, namandla okushaja ngokushesha.Nokho, njenganoma yibuphi ubuchwepheshe, beza nezinkinga zabo zokusebenza nezokuphepha.
Ukusebenza kwezimotolithium amandla ibhethriibalulekile ekusebenzeni kwayo nokuhlala isikhathi eside.Okunye okukhathaza kakhulu ngamabhethri e-lithium-power ukuwohloka kwawo ngokuhamba kwesikhathi.Njengoba ibhethri lishajwa futhi lishajwa ngokuphindaphindiwe, izinto ezisebenzayo ngaphakathi ziwohloka kancane kancane, okuholela ekwehleni komthamo webhethri lilonke.Ukuze kunqandwe le nkinga, abakhiqizi bebelokhu besebenzela ukuthuthukisa izinto ze-electrode yebhethri kanye nokwakheka kwe-electrolyte, okuthonya ukusebenza kwebhethri ngokuqondile.
Enye inkinga yokusebenza ephakama nayoamabhethri e-lithium amandlakuyisimo se-thermal runaway.Lokhu kwenzeka lapho ibhethri ithola ukwenyuka okungalawuleki kwezinga lokushisa, okuholela ekwenyukeni okuzinzile kokukhiqiza ukushisa.Ukushisa okushisayo kungase kuqaliswe izici ezihlukahlukene, njengokushaja ngokweqile, ukushajwa ngokweqile, ukudlula imikhawulo yokushisa, noma ukulimala ngokomzimba ebhethrini.Uma ukugijima okushisayo kuqala, kungaholela ekuhlulekeni okuyinhlekelele, okubangela imililo noma ukuqhuma.
Ukuze kuncishiswe ubungozi bokuphepha obuhlobene namabhethri wamandla e-lithium, kusetshenziswe izinyathelo ezimbalwa.Amasistimu okuphatha ibhethri (BMS) adlala indima ebalulekile ekuqapheni nasekulawuleni izinga lokushisa lebhethri, i-voltage, namaleveli amanje.Uma ipharamitha idlula ibanga eliphephile, i-BMS ingathatha izinyathelo zokuvimbela, njengokuvala ibhethri noma ukuvula amasistimu okupholisa.Ukwengeza, abakhiqizi bebesebenzisa izici ezihlukene zokuphepha, okuhlanganisa izindawo ezivalekile zebhethri ezingavimbeli ilangabi nezinto ezithuthukisiwe ze-elekthronikhi, ukuze kuncishiswe ubungozi bokubaleka kokushisa.
Ngaphezu kwalokho, kwenziwa ucwaningo lokuthuthukisa izinto ezintsha nemiklamo ethuthukisa ukuphepha kwamabhethri anamandla e-lithium.I-avenue eyodwa ethembisayo ukusetshenziswa kwama-electrolyte esimo esiqinile, anokuqina okushisayo okuphakeme uma kuqhathaniswa nama-electrolyte oketshezi endabuko.Amabhethri esimo esiqinile awanciphisi nje kuphela ubungozi bokubaleka kokushisa kodwa futhi anikeza ukuminyana kwamandla aphezulu, ukuphila okude, namazinga okushaja asheshayo.Kodwa-ke, ukudayiswa kwabo okusabalele kusasetshenzwa ngenxa yezinselelo zokukhiqiza nokucatshangelwa kwezindleko.
Imithethonqubo namazinga nawo abalulekile ekuqinisekiseni ukuphepha nokusebenza kwamabhethri anamandla e-lithium ezimoto.Izindikimba zamazwe ngamazwe njenge-International Electrotechnical Commission (IEC) kanye neNhlangano Yezizwe Ezihlangene zisungule imihlahlandlela yokuhlola nokuthuthwa kwamabhethri e-lithium.Abakhiqizi kumele balandele le mithethonqubo ukuze baqinisekise ukuthi yaboamabhethriukuhlangabezana nezidingo ezidingekayo zokuphepha.
Sengiphetha, ngenkathi amabhethri amandla e-lithium ezimoto enikeza izinzuzo eziningi, izindaba zokusebenza nezokuphepha akufanele zishaywe indiva.Ucwaningo oluqhubekayo nokuthuthukiswa kubalulekile ekuthuthukiseni ukusebenza kwebhethri, ekwehliseni ubungozi bokuphuma kokushisa, kanye nasekuthuthukiseni ukuphepha kwayo kukonke.Ngokusebenzisa amasistimu okuphatha amabhethri athuthukile, kusetshenziswa izinto ezintsha, kanye nokunamathela emithethweni eqinile, imboni yezimoto ingaqhubeka nokusebenzisa amandla amabhethri e-lithium, iqinisekise ulwazi lokushayela oluphephile nolusebenzayo kubathengi.
