Kusukela kwathuthukiswa ubuchwepheshe bebhethri, izinhlobo eziningi zezindlela ezisetshenziswa ukulinganisa i-SOC sezivele zenzekile. Kunezindlela ezididiyelwe zamanje ezihlanganisiwe, ukumelana nebhethri kwangaphakathi, izindlela zokuhlola zokukhipha, izindlela zamandla kagesi wesekethe evulekile, ama-voltage okulayisha, nezindlela zokuhlunga ze-Kalman ezintsha. Ithiyori enengqondo engaqondakali kanye nenethiwekhi ye-neural, njll.

Okwamanje kungenye yezindlela ezivame kakhulu zokulinganisa ze-SOC emkhakheni wesistimu yokuphatha ibhethri, futhi umongo ukulinganisa i-SOC yebhethri ngokuqongelela noma ukulahla ugesi ngokunqwabelana noma ukushajwa ngokunqwabelana noma ukushajwa. Ngesikhathi esifanayo, ngokwezinga lokukhishwa kanye nokushisa kwebhethri. Isinxephezelo esithile se-SOC elinganiselwe.

Uma ibhethri lichazwa ngokuthi SOCT0 lapho ibhethri iqala ukushajwa futhi ikhipha isimo sokuqala, khona-ke umthamo osele webhethri we-SOC ngemva kwe-T uthi: q, Q umthamo olinganiselwe webhethri, futhi N ukushaja nokukhipha ukusebenza kahle, okubizwa nangokuthi ukusebenza kahle kwe-coulomb, inani layo Ukushaja kwebhethri nezinga lokukhipha kunqunywa, mina ngingumthamo wamanje we-T. Indlela yamanje ehlanganisiwe ilula futhi ithembekile kunezinye izindlela zokulinganisa ze-SOC, futhi inani le-SOC lebhethri lingalinganiswa ngokushintshashintshayo, ngakho lisetshenziswa kabanzi. Kodwa-ke, le ndlela futhi inemikhawulo emibili: eyodwa, indlela yamanje ebalulekile idinga inani lokuqala le-SOC lebhethri kusengaphambili, futhi iqoqa ngokunembile okwamanje egeleza ngaphakathi noma ephuma ebhethrini, ukuze wenze iphutha lokulinganisa libe lincane ngangokunokwenzeka; okwesibili, Le ndlela isekelwe kuphela esicini sangaphandle sebhethri, futhi izinga lokuzikhipha kwebhethri, izinga lokuguga, kanye nesilinganiso sokushaja nokukhipha kwebhethri ye-SOC azinakwa ngokwezinga elithile.

Ukusetshenziswa kwesikhathi eside kungabangela iphutha lokulinganisa ukuthi likhule, ngakho-ke kuyadingeka ukwethula ama-coefficients okulungisa ahlobene Lungisa amaphutha okunqwabelana. (2) Indlela Yokuhlola Ukulahla Indlela yokuhlola yokukhipha iwukuba ukhiphe njalonjalo okwamanje kuze kube i-voltage yokunqamuka yebhethri, phindaphinda isikhathi esisetshenziswa yile nqubo yokukhipha ngenani losayizi wamanje wokukhipha, okungukuthi, umthamo osele webhethri. Indlela ngokuvamile isebenzisa le ndlela njengendlela yokulinganisa yebhethri ye-SOC noma ekugcinweni sekwephuzile kwebhethri, futhi ilula, ithembekile, futhi umphumela unemba uma kuqhathaniswa ngaphandle kokwazi inani le-SOC lebhethri.

Konke ngempumelelo. Nokho, kukhona ukushiyeka okubili endleleni yokuhlola ukukhishwa: Okokuqala, inqubo yokuhlola yale ndlela idinga isikhathi esiningi; okwesibili, uma usebenzisa le ndlela, kuyadingeka ukususa ibhethri elihlosiwe emotweni kagesi, ngakho-ke indlela ayikwazi ukusetshenziselwa ukubala ibhethri yamandla esimweni sokusebenza. (3) Indlela ye-voltage yesifunda evulekile isekelwe ebudlelwaneni boshintsho phakathi kwe-voltage yokuvula yebhethri ne-OCOTAGE, OCV) kanye nokugxiliswa kwe-lithium ion yangaphakathi yebhethri, futhi ifanelana ngokungaqondile ubuhlobo obuhambisanayo phakathi kwayo nebhethri SOC.

Lapho kwenziwa ukusebenza kwangempela, kuyadingeka ukukhulula ibhethri ngemva kokuba ibhethri seligcwaliswe ngesilinganiso esinqunyiwe sokukhipha (ngokuvamile u-1c) kuze kumiswe ukukhishwa, futhi ubudlelwano phakathi kwe-OCV ne-SOC butholakala ngokuvumelana nenqubo yokukhipha. Uma ibhethri lisesimeni sangempela sokusebenza, i-SOC yebhethri yamanje ingatholwa ngokuthola ithebula elihlobene le-OCV-SoC ngokwenani le-voltage kuzo zombili iziphetho zebhethri. Nakuba indlela iphumelela kumabhethri ahlukahlukene, iphinde ibe khona ukukhubazeka ngokwawo: Okokuqala, ibhethri eliqondiwe kufanele livunyelwe ukuthi lime ngaphezu kwehora elingu-1 ngaphambi kokulinganisa i-OCV, ngaleyo ndlela isabalalise ngokufanayo i-electrolyte yangaphakathi ebhethrini ukuze ithole i-voltage yokugcina ezinzile; okwesibili, ibhethri isemazingeni okushisa ahlukene Noma phakathi nokuphila okuhlukile, nakuba isifunda esivulekile siyafana, empeleni i-SOC ingase ihluke, futhi umphumela wokulinganisa awuqinisekisiwe ukuthi unembile ngokuphelele ukusetshenziswa kwesikhathi eside kwale ndlela.

Ngakho-ke, indlela ye-voltage yesekethe evulekile iyafana nendlela yokuhlola yokukhipha, ayisebenzi esilinganisweni sebhethri ye-SOC esebenzayo. (4) Indlela yokuhlunga ye-Kalman Indlela yokuhlunga ye-KALMAN iwuhlobo olusha lwedatha yokuzihlehlisa ethuthukisiwe ehlungwe kokuthi "Izimpumelelo Ezintsha Zokuhlunga Komugqa kanye Nethiyori Yokubikezela" ngawo-1960. i-algorithm.

Ingqikithi ye-algorithm iwukuthi isimo sesistimu eguquguqukayo eyinkimbinkimbi singalungiselelwa isimo sesistimu eguquguqukayo eyinkimbinkimbi ngokuvumelana nesimiso se-meawns encane. Amasistimu aguquguqukayo angawolayini azoba ngomugqa abe yimodeli yesikhala yesifunda yesistimu ngendlela yokuhlunga ye-Kalman. Uma uhlelo lokusebenza lwangempela, isistimu ibuyekezwa ngevelu ephawuliwe yesikhathi samanje, ilandelwa ivelu ephawuliwe yesikhathi samanje.

Imodi ethi "Isibikezelo - Ukulinganisa - Ukulungiswa", esusa ukuchezuka nokuphazamiseka kohlelo okungahleliwe. Uma i-SOC ye-powertrain ilinganiswa kusetshenziswa indlela yokuhlunga ye-Kalman, ibhethri liguqulwa libe imodeli yesikhala yesifunda ngendlela yesistimu yamandla, futhi i-SOC iba ukuguquguquka kwesimo ngaphakathi kwemodeli. Isistimu esunguliwe iyisistimu eqondile yomugqa.

Njengoba indlela yokuhlunga ye-Kalman ingalungisi kuphela iphutha lokuqala lesistimu, ingakwazi ukucindezela ngokuphumelelayo umsindo wesistimu, ngakho-ke kunenani elibalulekile lesicelo ekulinganisweni kwe-SOC yamabhethri amandla emoto kagesi ezimeni zokusebenza. Kodwa-ke, le ndlela iphinde ibe namaphutha anamaphuzu amabili: eyodwa, indlela yokuhlunga ye-Kalman ilinganisela ukunemba kwe-SOC kuncike kakhulu ekunembeni kwemodeli yebhethri, izici zokusebenza ngokwazo ziyibhethri lamandla angenawo umugqa, ngendlela yokuhlunga ye-Kalman Ngemva komugqa, akunakugwenywa ukuthi alikho iphutha, futhi uma imodeli isungulwe, umphumela ulinganiselwe; okwesibili, indlela ehilelekile iyinkimbinkimbi kakhulu, inani lokubala likhulu ngokwedlulele, futhi isikhathi sokubala esibaliwe side, kanye nezidingo zokusebenza kwe-Hardware. (5) Indlela yenethiwekhi ye-neural indlela yenethiwekhi ye-neural iwubuchopho bomuntu be-analog kanye ne-neuron yayo esetshenziselwa ukubhekana nohlobo olusha lwe-algorithm yezinhlelo ezingaqondile.

Ayidingi ucwaningo olujulile lwesakhiwo sangaphakathi sebhethri, ivele ikhiphe inombolo enkulu yezimpawu zokusebenza kubhethri eliqondiwe kusenesikhathi. Faka inani le-SOC ngesikhathi uqalisa isampula yokuphumayo bese ulifaka kusistimu esungulwe ngokusebenzisa indlela. Indlela ilula uma kuqhathaniswa ekucutshungulweni kwakamuva, okungukuthi, ingagwema ngempumelelo iphutha lendlela yokuhlunga ye-Kalman ukwenza imodeli yebhethri njengomugqa, futhi ingathola amapharamitha ashukumisayo ebhethri ngesikhathi sangempela.

Kodwa-ke, ivolumu yokusebenza kwangaphambilini kwendlela yenethiwekhi ye-neural inkulu uma kuqhathaniswa, futhi inani elikhulu ledatha yesampula eqondisiwe eyengeziwe futhi ebanzi iyadingeka ukuze kuqeqeshwe uhlelo. Indlela yokuqeqeshwa kwedatha nokuqeqeshwa ithinta kakhulu ukunemba kwesilinganiso se-SOC. Ngaphezu kwalokho, ngaphansi kwesenzo esiyinkimbinkimbi sokushisa kwebhethri, isilinganiso sokuzikhipha kanye nokuguga kwebhethri, indlela isetshenziselwa ukulinganisa inani le-SOC lesethi efanayo yamabhethri isikhathi eside, futhi ukunemba kwayo kuzoba isaphulelo esikhulu.

Ngakho-ke, le ndlela ayivamile kakhulu emsebenzini wokulinganisa we-SOC webhethri lamandla.
