Umkhiqizi webhethri le-lithium-ion uhlaziye indlela yokushaja yebhethri ye-lithium ion yokulingana. Uma iphakethe lebhethri le-lithium-ion lishajwe kakhulu, umthelela wokuziba umehluko phakathi komthamo webhethri elilodwa uyazitshwa, futhi ibhethri livamise ukugcwaliswa. Idizayini yesekethe yokuvikela ingahlangabezana nokuvikelwa kwephakethe lebhethri le-lithium ion ye-serial, ukuvikelwa kuqediwe, kungakhokhisa ngokuthembekile, ukuvikela kokukhipha ngokweqile, futhi kuzuze umsebenzi wokushaja ngokulingana.

Umkhiqizi webhethri ye-lithium-ion ukuhlaziya i-tandide i-lithium ion yebhethri ye-equilibrium yokushaja uchungechunge lwebhethri ye-lithium ion yinto evamile ekuhlanganiseni kwephakethe lebhethri. 1. Inombolo yama-PWM azoxhunywa ochungechungeni lwamabhethri e-lithium ion ngu-2 ¡Á (N-1), futhi n inombolo yamabhethri.

Uma kuqhathaniswa nokunye okwengeziwe. Ngaphezu kwalokho, ukudluliswa kwamandla kungadluliswa kuphela ukusuka ebhethrini kuya ebhethrini eliseduze nalo. Uma inani lamabhethri lingaphezulu, i-algorithm yokulawula iyinkimbinkimbi, khona-ke inkinga eyinhloko yizindleko kuphela.

2, i-tandem lithium ion ibhethri, uma usebenzisa i-BQ78PL114 + BQ76PL102, ungaphatha amabhethri ayi-8. Uma imoto kagesi kufanele ibe ngu-80, khona-ke amaphakethe ebhethri anjalo ayi-10 aphathwa ngokwehlukana, njengokuthi, izindleko zintsha. Ngakho-ke le IC kufanele ibe iphakethe lebhethri le-lithium-ion, i-12.

8V iphakethe lebhethri le-lithium-ion, noma ibhethri lenothibhukhi, noma ibhethri lebhayisikili likagesi, noma ibhethri lekhompuyutha ephathekayo. 3, i-tandem lithium ion ibhethri mayelana nemvamisa ye-PWM, umjikelezo womsebenzi, umthamo we-inductance, ezintathu zihlobene. Imvamisa enconyiwe ye-Ti&39;s IC ngu-200kHz, enganciphisa i-inductance, ngaleyo ndlela yehlise izindleko.

Ibhethri ye-lithium-ion ikhonjwa ibhethri ngenxa yebhethri enqubweni yokukhiqiza, kusukela kufilimu yokuhlanganisa ukuze ibe umkhiqizo oqediwe ukuze kudlule izinyathelo eziningi. Ngisho nezinqubo zokubona eziqinile, i-voltage, ukumelana, umthamo wesethi ngayinye yamandla iyahambisana, kodwa futhi izovela kanje noma umehluko onjalo. Njengewele likamama, lingase likhule lapho likhona manje, futhi kunzima ukulihlukanisa njengomama.

Kodwa-ke, lapho izingane ezimbili zikhula, kuzoba khona umehluko onjalo noma onjalo kumabhethri e-lithium. Ngemuva kokusebenzisa umehluko esikhathini esithile, kunzima ukufaka ibhethri ye-lithium. Uma ibhethri ye-lithium-ion ishajwa ngochungechunge, kufanele iqinisekise ukuthi ibhethri ngalinye lilinganiselwe, ngaphandle kwalokho izophazamisa ukusebenza nempilo yalo lonke isethi yamabhethri phakathi nokusetshenziswa.

Amasu okushaja ibhalansi asetshenziswa njalo anokulingana kokumelana kwe-shunt, ukushaja kokumelana nokulinganisa kwe-shunt, ukushaja okulinganayo kokulinganisa kwamandla ebhethri, ukushaja kwe-capacitance equalization ukushaja, ukushaja okulinganayo kwesiguquli esisuka phansi, ukushaja kokulinganisa kwe-inductance, njll.
