Izinto zebhethri ze-lithium zinezici ezithile ezivimbela ukuthi zingabixiwa ngokweqile, ngaphezulu-kukhishwe, ngaphezulu-Okwamanje, okufushane, futhi kukhokhiswe futhi kwakhishwa emazingeni okushisa aphezulu aphezulu futhi aphansi. Ngakho-ke, i-Lithium Battery Pack izohlala ihambisana ne-BMS entekenteke. I-BMS ibhekisa kuUhlelo Lokuphathwa Kwebhethriibhethri. Uhlelo lokuphatha, olubizwa nangokuthi iBhodi Lokuvikela.
Umsebenzi we-BMS
(1) Ukuqonda kanye nokulinganisa kokulinganisa ukuzwa isimo sebhethri
Lokhu kungumsebenzi oyisisekelo weI-BMS, kufaka phakathi ukukalwa nokubalwa kwamapharamitha wenkomba, kufaka phakathi i-voltage, yamanje, izinga lokushisa, amandla, i-soh (isimo sezempilo), i-sop (isimo samandla), i-sop amandla).
I-SOC ingaqondakala ngokuvamile njengoba kusele amandla ebhethri, futhi inani laso liphakathi kuka-0-100%. Le yipharamitha ebaluleke kakhulu ku-BMS; I-SOH ibhekisela esimweni sezempilo sebhethri (noma izinga lokuwohloka kwebhethri), okuyikhono langempela lebhethri lamanje. Uma kuqhathaniswa nomthamo olinganiselwe, lapho i-soh iphansi kune-80%, ibhethri alikwazi ukusetshenziswa endaweni yamandla.
(2) i-alamu nokuvikelwa
Lapho ukuhlukunyezwa kwenzeka ebhethri, i-BMS ingakwazisa isiteji ukuvikela ibhethri futhi ithathe izinyathelo ezihambelanayo. Ngasikhathi sinye, imininingwane ye-alamu engajwayelekile izothunyelwa kwipulatifomu yokuqapha kanye nokuphatha futhi ikhiqize amazinga ahlukene imininingwane ye-alamu.
Isibonelo, lapho izinga lokushisa lishisa ngokweqile, i-BMS izoyinqamula ngokuqondile icala nenkokhelo futhi yenza ukuvikelwa ngokweqile, bese ithumela i-alamu ngemuva.
Amabhethri e-Lithium azokhipha izingxwayiso ikakhulukazi ngezinkinga ezilandelayo:
Ukuchithwa: Iyunithi elilodwa ngaphezulu-voltage, inani eliphelele ngaphezulu-voltage, ukushaja ngaphezulu-okwamanje;
Ukuphuma ngokweqile: Iyunithi elilodwa ngaphansi-voltage, voltage ephelele ngaphansi-voltage, khipha ngaphezulu-okwamanje;
Ukushisa: izinga lokushisa lebhethri liphezulu kakhulu, izinga lokushisa elikhona liphezulu kakhulu, izinga lokushisa le-mos liphezulu kakhulu, izinga lokushisa lebhethri liphansi kakhulu, futhi izinga lokushisa elikhona liphansi kakhulu;
Isimo: Ukucwiliswa kwamanzi, ukushayisana, ukungenelela, njll.
(3) Ukuphathwa ngokulinganayo
Isidingo seUkuphathwa ngokulinganayokuvela ekungeneni kokukhiqizwa kwebhethri nokusetshenziswa kwebhethri.
Ngokombono wokukhiqiza, ibhethri ngalinye linomjikelezo walo wokuphila kanye nezimpawu. Awekho amabhethri amabili afanayo. Ngenxa yokungahambelani kwabahlukanisi, ama-Cathode, anode nezinye izinto, amakhono amabhethri ahlukene awakwazi ukuvumelana ngokuphelele. Isibonelo, izinkomba zokungaguquguquki zomehluko we-voltage, ukumelana kwangaphakathi, njll. Iseli ngalinye lebhethri elenza i-48V / 20AH yebhethri yebhethri iyahlukahluka ngaphakathi kwebanga elithile.
Ngokombono wokusebenzisa, inqubo yokuphendula ye-electrochemical ayisoze yaguquguquka ngesikhathi sokushaja kwebhethri nokukhipha. Noma ngabe kuyiphakethe lebhethri elifanayo, ukushaja kwebhethri nokukhipha umthamo kuzohluka ngenxa yamazinga okushisa ahlukahlukene kanye namazinga okushayisana, okuholela kumakhono webhethri angahambelani.
Ngakho-ke, ibhethri lidinga ukulinganisa kokulinganisa nokulinganisa okusebenzayo. Lokho ukubeka imibundu yokuqalisa nokuqeda ukulingana: ngokwesibonelo, eqenjini lamabhethri, ukulingana kuyaqalwa lapho umehluko phakathi kwenani elikhulu leqembu kanye namandla kagesi aphakathi nendawo afinyelela ku-5MV.
(4) Ukuxhumana nokubeka isikhundla
I-BMS ine-ahlukilemodule yezokuxhumana, ebhekele ukuhanjiswa kwedatha kanye nokuma kwebhethri. Ingadlulisela idatha efanelekile ezwakala futhi ilinganiswe kwipulatifomu yokuphathwa kokusebenza ngesikhathi sangempela.
