Ephaketheni lebhethri le-lithium, ezimbalwaamabhethri e-lithiumaxhunywe ochungechungeni ukuze athole i-voltage edingekayo yokusebenza. Uma udinga umthamo ophakeme kanye namandla aphezulu, kufanele uxhume amabhethri e-lithium amandla ngokuhambisana, iKhabhinethi yokuguga yemishini yokuhlanganisa ibhethri ye-lithium ingakwazi ukuqina kwamandla aphezulu kanye nezinga eliphezulu lomthamo ngokuhlanganisa izindlela ezimbili zochungechunge nokuxhumeka okufanayo.
1, uchungechunge lwebhethri ye-lithium kanye nendlela yokuxhumana efanayo
Ukuxhumana okuhambisanayo kweamabhethri e-lithium: i-voltage ayishintshile, umthamo webhethri uyengezwa, ukumelana kwangaphakathi kuyancishiswa, futhi isikhathi sokunikezwa kwamandla singanwetshwa.
Ukuxhuma kochungechunge lwebhethri ye-lithium: i-voltage yengezwe, umthamo awushintshiwe.Uxhumano oluhambisanayo ukuze uthole amandla engeziwe, ungaxhuma amabhethri amaningi ngokuhambisana.
Enye indlela yokuxhuma amabhethri ngokuhambisana ukusebenzisa amabhethri amakhulu, njengoba kunenani elilinganiselwe lamabhethri angasetshenziswa futhi le ndlela ayifaneleki kuzo zonke izinhlelo zokusebenza.
Ngaphezu kwalokho, amaseli amakhulu awafanele uhlobo lwefomu oludingekayo kumabhethri akhethekile. Amakhemistri amaningi ebhethri angasetshenziswa ngokuhambisana, futhiamabhethri e-lithiumzifaneleka kakhulu ukusetshenziswa parallel.
Isibonelo, ukuxhumeka okuhambisanayo kwamaseli amahlanu kugcina ivolumu yebhethri iku-3.6V futhi kwandisa isikhathi samanje nesikhathi sokusebenza nge-factory emihlanu. Amaseli e-impedance aphezulu noma "avulekile" anomphumela omncane kumjikelezo ofanayo kunoxhumano lochungechunge, kodwa iphakethe lebhethri elihambisanayo lehlisa umthamo wokulayisha kanye nesikhathi sokusebenza.
Uma kusetshenziswa uchungechunge noxhumo oluhambisanayo, idizayini ivumelana nezimo ngokwanele ukuze kuzuzwe amandla kagesi kanye nezilinganiso zamanje ezidingekayo kumasayizi webhethri ajwayelekile.
Kumele kuqashelwe ukuthi amandla aphelele awashintshi ngenxa yezindlela ezihlukene zokuxhuma i-lithium battery spot welders zokukhiqiza ibhethri ye-lithium.
Amandla alingana ne-voltage ephindaphindwa amandla amanje. Ngobaamabhethri e-lithium, uchungechunge nezindlela zokuxhuma ezihambisanayo zivamile. Elinye lamaphakethe ebhethri asetshenziswa kakhulu yibhethri ye-lithium engu-18650, enomjikelezo wokuvikela, kanye nebhodi lokuvikela ibhethri le-lithium.
Ibhodi lokuvikela ibhethri le-lithium lingakwazi ukuqapha ibhethri ngalinye elixhunywe ochungechungeni, ngakho-ke umthamo walo wangempela wangempela ngu-42V. Le sekhethi yokuvikela ibhethri ye-lithium (okungukuthi ibhodi lokuvikela ibhethri le-lithium) ingasetshenziswa futhi ukuqapha isimo sebhethri ngalinye elixhunywe ochungechungeni.
Lapho usebenzisa i-18650amabhethri e-lithiumochungechungeni, izidingo eziyisisekelo ezilandelayo kufanele zilandelwe: i-voltage kufanele ihambisane, ukumelana kwangaphakathi akufanele kudlule ama-milliamp angu-5, futhi umehluko womthamo akufanele udlule ama-milliamp angu-10. Okunye ukugcina izindawo zokuxhuma zamabhethri zihlanzekile, Iphuzu ngalinye lokuxhuma linokumelana okuthile. Uma amaphuzu okuxhuma engahlanzekile noma amaphuzu okuxhumeka anyuswa, ukumelana kwangaphakathi kungase kube phezulu, okungase kuthinte ukusebenza kwephakethe lebhethri ye-lithium yonke.
2, uchungechunge lwebhethri ye-lithium-parallel uxhumano izinyathelo zokuphepha
Ukusetshenziswa okuvamile kweamabhethri e-lithiumochungechungeni kanye nesidingo esihambisanayo sokufeza ukubhanqa kwebhethri ye-lithium yebhethri, izindinganiso zokumatanisa: umehluko we-lithium battery cell voltage ≤ 10mV, ibhethri ye-lithium cell umehluko wangaphakathi wokumelana ≤ 5mΩ, umehluko webhethri ye-lithium cell ≤ 20mA.
Amabhethri kufanele axhunywe ngokuhambisana nohlobo olufanayo lwebhethri. Amabhethri ahlukene anama-voltage ahlukene, futhi lapho exhunywe ngokuhambisana, amabhethri anama-voltage aphezulu ashaja amabhethri ngama-voltage aphansi, amandla adlayo.
Amabhethri akuchungechunge kufanele futhi asebenzise ibhethri elifanayo. Uma kungenjalo, lapho amabhethri anamandla ahlukene exhunywe ochungechungeni (isb, uhlobo olufanayo lwamabhethri anamazinga ahlukene obusha nobudala), ibhethri elinamandla amancane lizokhipha ukukhanya kuqala, futhi ukumelana kwangaphakathi kuzokwanda, ngaleso sikhathi ibhethri elinomthamo omkhulu lizokhishwa ngokumelana kwangaphakathi kwebhethri elinomthamo omncane, lidla ugesi, futhi lizoyishaja futhi. Ngakho-ke i-voltage emthwalweni izoncishiswa kakhulu, futhi ayikwazi ukusebenza, umthamo webhethri ulingana nomthamo omncane webhethri.
