Njengomthombo wamandla oyinhloko wezimoto ezintsha zamandla, amabhethri kagesi abaluleke kakhulu ezimotweni zamandla amasha.Ngesikhathi sokusetshenziswa kwangempela kwemoto, ibhethri izobhekana nezimo zokusebenza eziyinkimbinkimbi nezishintshayo.
Emazingeni okushisa aphansi, ukumelana kwangaphakathi kwamabhethri e-lithium-ion kuzokwanda futhi umthamo uzokwehla.Ezimweni ezimbi kakhulu, i-electrolyte izoba yiqhwa futhi ibhethri alikwazi ukushajwa.Ukusebenza okuphansi kwezinga lokushisa kwesistimu yebhethri kuzothinteka kakhulu, okuholela ekusebenzeni kokuphuma kwamandla kwezimoto zikagesi.Ukufiphala nokunciphisa ububanzi.Lapho ushaja izimoto zamandla amasha ngaphansi kwezimo eziphansi zezinga lokushisa, i-BMS evamile iqala ngokushisisa ibhethri libe izinga lokushisa elifanele ngaphambi kokushaja.Uma ingaphathwa kahle, izoholela ekushajweni kwamandla kagesi ngokushesha, okuholela ekujikelezeni okufushane kwangaphakathi, futhi kuqhume intuthu, umlilo noma ngisho nokuqhuma.
Ezingeni lokushisa eliphezulu, uma isilawuli seshaja sihluleka, kungase kubangele ukusabela kwamakhemikhali okunodlame ngaphakathi kwebhethri futhi kukhiphe ukushisa okukhulu.Uma ukushisa kunqwabelana ngokushesha ngaphakathi kwebhethri ngaphandle kwesikhathi sokuhlakazeka, ibhethri lingavuza, liphume, libheme, njll. Ezimeni ezimbi kakhulu, ibhethri lizovutha ngamandla futhi liqhume.
Uhlelo lokulawula ukushisa kwebhethri (Isistimu Yokulawula Ukushisa Kwebhethri, i-BTMS) iwumsebenzi oyinhloko wesistimu yokulawula ibhethri.Ukuphathwa okushisayo kwebhethri ikakhulukazi kuhlanganisa imisebenzi yokupholisa, ukufudumeza nokulinganisa izinga lokushisa.Imisebenzi yokupholisa nokushisisa ilungiswa ngokuyinhloko ngomthelela ongaba khona wezinga lokushisa le-ambient yangaphandle kubhethri.Ukulinganisa izinga lokushisa kusetshenziselwa ukunciphisa umehluko wezinga lokushisa ngaphakathi kwephakethe lebhethri futhi kuvimbele ukubola okusheshayo okubangelwa ukushisa ngokweqile kwengxenye ethile yebhethri.Isistimu yokulawula iluphu evaliwe yakhiwe ngendlela ebamba ukushisa, iyunithi yokulinganisa nokulawula, kanye nemishini yokulawula izinga lokushisa, ukuze ibhethri lamandla likwazi ukusebenza ngaphakathi kwebanga lokushisa elifanele ukuze ligcine isimo salo sokusebenzisa kahle futhi liqinisekise ukusebenza nempilo yebhethri. uhlelo lwebhethri.
1. Imodi yokuthuthukisa imodeli ye-"V" yesistimu yokuphatha okushisayo
Njengengxenye yesistimu yebhethri yamandla, isistimu yokuphatha okushisayo nayo ithuthukiswa ngokuhambisana nemodeli yokuthuthukiswa kwemodeli ye-V "yemboni yezimoto. Ngosizo lwamathuluzi okulingisa kanye nenani elikhulu lokuqinisekisa ukuhlolwa, ngale ndlela kuphela lapho i- ukusebenza kahle kwentuthuko kuthuthukiswe, izindleko zokuthuthukiswa kanye nohlelo lwesiqinisekiso kugcinwe ukwethembeka, ukuphepha nokuphila isikhathi eside.
Okulandelayo imodeli "V" yokuthuthukiswa kwesistimu yokuphatha okushisayo.Ngokuvamile, imodeli iqukethe izimbazo ezimbili, eyodwa enezingqimba neyodwa mpo: i-eksisi evundlile yakhiwe imigqa emine eyinhloko yokuthuthukiswa okuya phambili kanye nomugqa owodwa oyinhloko wokuqinisekisa okuphambene, futhi umugqa oyinhloko ukuthuthukiswa phambili., kucatshangelwa ukuqinisekiswa kwe-loop evaliwe ehlehla;i-eksisi eqondile inamazinga amathathu: izingxenye, amasistimu angaphansi kanye namasistimu.
Izinga lokushisa lebhethri lithinta ngqo ukuphepha kwebhethri, ngakho-ke ukuklama nokucwaninga kwesistimu yokulawula ukushisa kwebhethri kungomunye wemisebenzi ebaluleke kakhulu ekwakhiweni kwesistimu yebhethri.Idizayini yokuphatha okushisayo nokuqinisekiswa kwesistimu yebhethri kufanele kwenziwe ngokuhambisana ngokuqinile nenqubo yokuklama yokulawula ukushisa kwebhethri, isistimu yokulawula ukufudumala kwebhethri nezinhlobo zezingxenye, ukukhetha kwengxenye yesistimu yokuphatha okushisayo, nokuhlola ukusebenza kwesistimu yokulawula ukushisa.Ukuze uqinisekise ukusebenza nokuphepha kwebhethri.
1. Izidingo zesistimu yokulawula ukushisa.Ngokuya ngamapharamitha wokufakwa kwedizayini okufana nendawo yokusebenzisa imoto, izimo zokusebenza zemoto, kanye newindi lokushisa kweseli yebhethri, yenza ukuhlaziya kwesidingo ukuze kucaciswe izidingo zesistimu yebhethri yesistimu yokulawula ukushisa;izidingo zesistimu, ngokusho kokuhlaziywa Kwezimfuneko kunquma imisebenzi yesistimu yokulawula ukushisa kanye nemigomo yokuklama yesistimu.Le migomo yokuklama ikakhulukazi ihlanganisa ukulawula izinga lokushisa kweseli yebhethri, umehluko wezinga lokushisa phakathi kwamaseli ebhethri, ukusetshenziswa kwamandla esistimu kanye nezindleko.
2. Uhlaka lwesistimu yokulawula ukushisa.Ngokuya ngezidingo zesistimu, isistimu ihlukaniswe yaba isistimu engaphansi yokupholisa, isistimu engaphansi yokushisisa, isistimu engaphansi yokufakwa kwe-thermal kanye nesistimu engaphansi ye-thermal runaway obstructin (TRo), futhi izidingo zokuklama zesistimu engaphansi ngayinye zichaziwe.Ngesikhathi esifanayo ukuhlaziywa kwe-Silation kwenziwa ukuze kuqinisekiswe ukwakheka kwesistimu.NjengeI-PTC cooler heater, I-heater ye-PTC, iphampu yamanzi kagesi, njll.
3. Idizayini ye-subsystem, qala ngokunquma inhloso yokuklama yesistimu engaphansi ngayinye ngokuya ngedizayini yesistimu, bese kukhethwa indlela, ukwakheka kohlelo, ukuklama okuningiliziwe nokuhlaziywa kokulingisa kanye nokuqinisekiswa kohlelo oluncane ngalunye ngokulandelana.
4. Ukuklanywa kwezingxenye, okokuqala thola izinhloso zokuklama izingxenye ngokuya ngedizayini yesistimu engaphansi, bese wenza umklamo onemininingwane nokuhlaziywa kokulingisa.
5. Ukukhiqiza nokuhlola izingxenye, ukukhiqizwa kwezingxenye, nokuhlolwa nokuqinisekisa.
6. Ukuhlanganiswa kwesistimu engaphansi nokuqinisekiswa, ukuhlanganiswa kwesistimu engaphansi nokuqinisekisa ukuhlolwa.
7. Ukuhlanganiswa kwesistimu nokuhlola, ukuhlanganiswa kwesistimu nokuqinisekisa ukuhlola.
