Njengomthombo oyinhloko wamandla wezimoto ezintsha zamandla, amabhethri kagesi abaluleke kakhulu ezimotweni ezintsha zamandla. Ngesikhathi sokusetshenziswa kwangempela kwemoto, ibhethri lizobhekana nezimo zokusebenza eziyinkimbinkimbi nezishintshashintshayo.
Uma izinga lokushisa liphansi, ukumelana kwangaphakathi kwamabhethri e-lithium-ion kuzokhula futhi amandla azoncipha. Ezimweni ezimbi kakhulu, i-electrolyte izoma futhi ibhethri ayikwazi ukukhishwa. Ukusebenza kwezinga lokushisa eliphansi kohlelo lwebhethri kuzothinteka kakhulu, okuholela ekusebenzeni kwamandla okukhipha izimoto zikagesi. Ukuncipha kokufiphala kanye nobubanzi. Uma ushaja izimoto ezintsha zamandla ngaphansi kwezimo zokushisa eziphansi, i-BMS ejwayelekile iqala ifudumeze ibhethri lifike ezingeni lokushisa elifanele ngaphambi kokushaja. Uma ingaphathwa kahle, kuzoholela ekushajeni ngamandla kagesi ngokushesha, okuholela ekushiseni okufushane kwangaphakathi, futhi kungase kwenzeke intuthu eyengeziwe, umlilo noma ngisho nokuqhuma.
Uma izinga lokushisa liphezulu, uma ukulawula ishaja kwehluleka, kungabangela ukusabela kwamakhemikhali okunamandla ngaphakathi kwebhethri futhi kudale ukushisa okuningi. Uma ukushisa kuqongelela ngokushesha ngaphakathi kwebhethri ngaphandle kwesikhathi sokunyamalala, ibhethri lingavuza, liphume uphethiloli, libheme, njll. Ezimweni ezimbi kakhulu, ibhethri lizosha ngamandla futhi liqhume.
Uhlelo lokuphatha ukushisa kwebhethri (i-Battery Thermal Management System, i-BTMS) luwumsebenzi oyinhloko wohlelo lokuphatha ibhethri. Ukuphathwa kokushisa kwebhethri kuhlanganisa kakhulu imisebenzi yokupholisa, ukushisa kanye nokulinganisa izinga lokushisa. Imisebenzi yokupholisa kanye nokushisa ilungiswa kakhulu ngenxa yomthelela ongaba khona wokushisa okungaphandle kwebhethri. Ukulinganisa izinga lokushisa kusetshenziselwa ukunciphisa umehluko wokushisa ngaphakathi kwephakethe lebhethri nokuvimbela ukubola okusheshayo okubangelwa ukushisa ngokweqile kwengxenye ethile yebhethri. Uhlelo lokulawula oluvaliwe lwakhiwe nge-medium eqhuba ukushisa, iyunithi yokulinganisa kanye nokulawula, kanye nemishini yokulawula izinga lokushisa, ukuze ibhethri lamandla likwazi ukusebenza ngaphakathi kwebanga lokushisa elifanele ukuze ligcine isimo salo sokusetshenziswa esifanele futhi liqinisekise ukusebenza kanye nokuphila kohlelo lwebhethri.
1. Imodi yokuthuthukiswa kwemodeli "V" yesistimu yokuphatha ukushisa
Njengengxenye yesistimu yebhethri yamandla, uhlelo lokuphatha ukushisa luphinde lwakhiwe ngokuhambisana nemodeli yokuthuthukiswa kwemodeli ye-V" yemboni yezimoto. Ngosizo lwamathuluzi okulingisa kanye nenani elikhulu lokuqinisekiswa kokuhlola, kungathuthukiswa ukusebenza kahle kwentuthuko, izindleko zokuthuthukiswa kanye nohlelo lwesiqinisekiso. Ukuthembeka, ukuphepha kanye nokuphila isikhathi eside.
Okulandelayo yimodeli ethi "V" yokuthuthukiswa kohlelo lokuphathwa kokushisa. Ngokuvamile, imodeli inezingqimba ezimbili, eyodwa evundlile kanye neyodwa eqondile: i-axis evundlile yakhiwe imigqa emine eyinhloko yokuthuthukiswa phambili kanye nomugqa owodwa oyinhloko wokuqinisekiswa okuphambene, kanti umugqa oyinhloko ukuthuthukiswa okuphambene. , uma kucatshangelwa ukuqinisekiswa okuvaliwe okuphambene; i-axis evundlile inamazinga amathathu: izingxenye, izinhlelo ezingaphansi kanye nezinhlelo.
Izinga lokushisa lebhethri lithinta ngqo ukuphepha kwebhethri, ngakho-ke ukuklama nokucwaninga kohlelo lokuphatha ukushisa kwebhethri kungenye yemisebenzi ebaluleke kakhulu ekwakhiweni kohlelo lwebhethri. Ukuklama nokuqinisekisa ukuphathwa kokushisa kwesistimu yebhethri kumele kwenziwe ngokuhambisana nenqubo yokuklama ukuphathwa kokushisa kwebhethri, uhlelo lokuphatha ukushisa kwebhethri nezinhlobo zezingxenye, ukukhethwa kwezingxenye zesistimu yokuphatha ukushisa, kanye nokuhlolwa kokusebenza kohlelo lokuphatha ukushisa. Ukuze kuqinisekiswe ukusebenza nokuphepha kwebhethri.
1. Izidingo zesistimu yokuphatha ukushisa. Ngokwemingcele yokufaka yokuklama njengendawo yokusetshenziswa kwemoto, izimo zokusebenza kwemoto, kanye nefasitela lokushisa leseli yebhethri, yenza ukuhlaziywa kwesidingo ukuze kucaciswe izidingo zesistimu yebhethri yesistimu yokuphatha ukushisa; izidingo zesistimu, ngokusho kokuhlaziywa kwezimfuneko kunquma imisebenzi yesistimu yokuphatha ukushisa kanye nezinhloso zokuklama zesistimu. Lezi zinhloso zokuklama zifaka phakathi ukulawulwa kwezinga lokushisa leseli yebhethri, umehluko wokushisa phakathi kwamaseli ebhethri, ukusetshenziswa kwamandla esistimu kanye nezindleko.
2. Uhlaka lwesistimu yokuphathwa kokushisa. Ngokwezidingo zesistimu, uhlelo luhlukaniswe ngesistimu yokupholisa, isistimu yokushisa, isistimu yokushisa engaphansi kanye nesistimu yokushisa egijimayo (TRo), futhi izidingo zokuklama zesistimu ngayinye engaphansi ziyachazwa. Ngesikhathi esifanayo, ukuhlaziywa kokulingisa kwenziwa ukuze kuqinisekiswe ukwakheka kwesistimu ekuqaleni. NjengokuthiIsifudumezi esipholile se-PTC, Isifudumezi somoya se-PTC, iphampu yamanzi kagesi, njll.
3. Ukuklama uhlelo olungaphansi, kuqala kunqunywe umgomo wokuklama wohlelo ngalunye olungaphansi ngokuya ngokuklama uhlelo, bese kwenziwa ukukhetha indlela, ukuklama uhlelo, ukuklama okuningiliziwe kanye nokuhlaziywa kokulingisa kanye nokuqinisekiswa kohlelo ngalunye olungaphansi ngokulandelana.
4. Ukuklama izingxenye, kuqala kunqume izinhloso zokuklama zezingxenye ngokuya ngokuklama kwesistimu engaphansi, bese kwenziwa ukuhlaziywa okuningiliziwe kokuklama nokulingisa.
5. Ukukhiqiza nokuhlola izingxenye, ukukhiqizwa kwezingxenye, kanye nokuhlola nokuqinisekisa.
6. Ukuhlanganiswa nokuqinisekiswa kwesistimu engaphansi, kokuhlanganiswa kwesistimu engaphansi kanye nokuqinisekiswa kokuhlolwa.
7. Ukuhlanganiswa nokuhlolwa kwesistimu, ukuhlanganiswa kwesistimu nokuqinisekiswa kokuhlolwa.
