Isingeniso：
Amabhethri ayingxenye ebalulekile yamadivayisi nezinhlelo eziningi, kusukela kuma-smartphone nama-laptop kuya ezimotweni kanye nendawo yokugcina amandla elanga. Ukwazi uhlobo lwebhethri olisebenzisayo kubalulekile ngezinjongo zokuphepha, ukulungiswa kanye nokulahla. Izinhlobo ezimbili ezivamile zamabhethri yilezii-lithium-ion (i-Li-ion)namabhethri e-lead-acid. Uhlobo ngalunye lunezici zalo futhi ludinga ukuphathwa okuhlukile. Kulesi sihloko, sizoxoxa ngendlela yokwazi ukuthi ibhethri liyi-lithium noma i-lead, kanye nomehluko omkhulu phakathi kwalokhu okubili.
Ukubukeka
Enye yezindlela ezilula zokuhlukanisa phakathi kwamabhethri e-lithium ne-lead-acid iwukubukeka kwawo ngokomzimba. Amabhethri e-lead-acid ngokuvamile makhulu futhi anzima kune-amabhethri e-lithium-ion.Ngokuvamile ziyisikwele noma ziyisikwele futhi zinesembozo esihlukile sokufaka amanzi. Uma kuqhathaniswa, amabhethri e-lithium-ion ngokuvamile mancane, alula, futhi eza ngezimo ezahlukahlukene, kufaka phakathi i-cylindrical kanye ne-prismatic. Azinazo izembozo zokufaka umoya futhi ngokuvamile zifakwe ebhokisini lepulasitiki.
Amathegi namathegi
Enye indlela yokuhlonza uhlobo lwebhethri ukuhlola amalebula nezimpawu ebhethri uqobo. Amabhethri e-lead-acid avame ukuba namalebula anjengalawa, futhi angase abe nezimpawu ezibonisa i-voltage kanye nomthamo. Ngaphezu kwalokho, amabhethri e-lead-acid avame ukuba namalebula okuxwayisa ngezingozi ze-sulfuric acid kanye nesidingo somoya ofanele. Amabhethri e-lithium-ion, ngakolunye uhlangothi, avame ukulebula ngolwazi mayelana nokwakheka kwamakhemikhali, i-voltage, kanye nomthamo wamandla. Angase futhi abe nezimpawu ezibonisa ukuhambisana nezindinganiso zokuphepha, njenge-UL (Underwriters Laboratories) noma i-CE (European Conformity Assessment).
I-voltage kanye nomthamo
I-voltage kanye nomthamo webhethri nakho kunganikeza izinkomba mayelana nohlobo lwayo. Amabhethri e-lead-acid ngokuvamile atholakala ngama-voltage angu-2, 6, noma angu-12 volts futhi avame ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu okukhipha, njengamabhethri okuqala imoto. Amabhethri e-lithium-ion, ngakolunye uhlangothi, anobuningi bamandla aphezulu, ngama-voltage asukela ku-3.7 volts yeseli elilodwa kuya ku-48 volts noma ngaphezulu kumaphakethe amakhulu ebhethri asetshenziswa ezimotweni zikagesi noma ezinhlelweni zokugcina amandla.
Izidingo zokulungisa
Ukuqonda izidingo zokunakekelwa kwebhethri kungasiza ekuboneni uhlobo lwayo. Amabhethri e-lead-acid adinga ukulungiswa njalo, okuhlanganisa ukuhlola nokugcwalisa amazinga e-electrolyte ngamanzi acwengekile, ukuhlanza ama-terminals, nokuqinisekisa ukuthi umoya ungena kahle ukuze kuvinjelwe ukunqwabelana kwegesi ye-hydrogen eqhumayo. Ngokuphambene nalokho,amabhethri e-lithium-ionazinazo izilungiso futhi azidingi ukunisela njalo noma ukuhlanzwa kwe-terminal. Kodwa-ke, zidinga ukuvikelwa ekushajeni ngokweqile nasekukhishweni kwamanzi okujulile ukuze kuvinjelwe umonakalo futhi kuqinisekiswe ukuthi zihlala isikhathi eside.
Umthelela emvelweni
Umthelela webhethri endaweni ezungezile ungaba yinto ebalulekile okufanele icatshangelwe lapho kunqunywa uhlobo lwebhethri. Amabhethri e-lead-acid aqukethe i-lead kanye ne-sulfuric acid, kokubili okungaba yingozi endaweni ezungezile uma kungaphathwa kahle. I-lead iyinsimbi enobuthi futhi i-sulfuric acid iyagqwala futhi ingabangela ukungcoliswa komhlabathi namanzi uma ingaphathwa kahle futhi ilahlwe. Amabhethri e-lithium-ion nawo aletha izinselele zemvelo ngenxa yokukhishwa kwe-lithium nezinye izinsimbi zomhlaba ezingavamile, okungaholela nasekubalekeni kokushisa kanye nemililo uma kungaphinde kusetshenziswe kahle. Ukuqonda umthelela webhethri endaweni ezungezile kungakusiza ukuthi wenze izinqumo ezinolwazi mayelana nokusetshenziswa kanye nokulahlwa kwebhethri.
Ukulahlwa kanye nokusetshenziswa kabusha
Ukulahlwa kahle kanye nokusetshenziswa kabusha kwamabhethri kubalulekile ekunciphiseni umthelela emvelweni kanye nokuqinisekisa ukuthi izinto ezibalulekile ziyatholwa. Amabhethri e-lead-acid avame ukusetshenziswa kabusha ukuze kutholwe i-lead kanye nepulasitiki, engasetshenziswa ukwenza amabhethri amasha kanye neminye imikhiqizo. Ukuphinda kusetshenziswe amabhethri e-lead-acid kusiza ukuvimbela ukungcoliswa kwe-lead kanye nokonga imithombo yemvelo.Amabhethri e-lithium-ionfuthi aqukethe izinto eziyigugu njenge-lithium, i-cobalt kanye ne-nickel, ezingaphinde zisetshenziswe futhi zisetshenziswe kumabhethri amasha. Kodwa-ke, ingqalasizinda yokuphinda kusetshenziswe amabhethri e-lithium-ion isathuthuka, futhi izinqubo ezifanele zokuphinda kusetshenziswe zibalulekile ekunciphiseni ukulimala kwemvelo.
Izinto okufanele uzicabangele ngokuphepha
Ukuphepha kuyisici esibalulekile lapho kuphathwa futhi kuhlonzwa amabhethri, ikakhulukazi amabhethri e-lithium-ion, aziwa ngokubaleka ekushiseni bese ebamba umlilo uma onakele noma eshajwe ngendlela engafanele. Ukuqonda izinyathelo zokuphepha zohlobo ngalunye lwebhethri kubalulekile ukuvimbela izingozi nokuqinisekisa ukuphathwa ngendlela efanele. Amabhethri e-lead-acid angakhipha igesi ye-hydrogen eqhumayo uma eshajwe kakhulu noma enqanyuliwe, futhi angabangela ukusha kwamakhemikhali uma i-electrolyte ithinta isikhumba noma amehlo. Izinyathelo zokuphepha ezifanele, njengokusebenzisa imishini yokuzivikela yomuntu siqu kanye nokulandela iziqondiso zomkhiqizi, zibalulekile lapho usebenza nanoma yiluphi uhlobo lwebhethri.
Isiphetho
Ngamafuphi, ukuhlonza ukuthi ibhethri liyi-lithium noma i-lead-acid kudinga ukucatshangelwa izici ezahlukahlukene, okuhlanganisa ukubukeka ngokomzimba, amalebula nezimpawu, i-voltage kanye nomthamo, izidingo zokugcinwa, umthelela wemvelo, izinketho zokulahla nokuvuselela kabusha, kanye nokucatshangelwa kokuphepha. Ngokuqonda umehluko phakathi kwamabhethri e-lithium-ion kanye ne-lead-acid, abantu ngabanye nezinhlangano bangenza izinqumo ezinolwazi mayelana nokusetshenziswa kwawo, ukunakekelwa, kanye nokulahlwa kwawo. Ukuhlonza nokuphatha kahle amabhethri kubalulekile ekuphepheni, ekuvikelweni kwemvelo kanye nokongiwa kwezinsiza. Uma ungabaza ngohlobo lwebhethri, kunconywa ukuthi uthintane nomkhiqizi noma uchwepheshe ofanelekayo ukuze uthole isiqondiso.
Uma unemibuzo noma ungathanda ukwazi okwengeziwe, sicela ungangabazi ukungithumelelaxhumana nathi.
