Intshayelelo:
Iitships ezinxulumene nombane bezisoloko ziluhlu lweemveliso ezifumene ingqalelo enkulu. Iitships zokukhusela ibhetri luhlobo lweetships ezinxulumene nombane ezisetyenziselwa ukubona iimeko ezahlukeneyo zempazamo kwiibhetri zeseli enye kunye neeseli ezininzi. Kwiinkqubo zebhetri zanamhlanje, iimpawu zeebhetri ze-lithium-ion zifanelekile kakhulu kwiinkqubo ze-elektroniki eziphathwayo, kodwaiibhetri ze-lithiumkufuneka isebenze ngaphakathi kwemida elinganisiweyo, igxile ekusebenzeni nasekukhuselekeni. Ke ngoko, ukhuseleko lweepakethi zebhetri ze-lithium-ion luyimfuneko kwaye lubalulekile. Ukusetyenziswa kwemisebenzi eyahlukeneyo yokukhusela ibhetri kukuthintela ukwenzeka kweemeko zempazamo ezifana nokukhupha i-OCD engaphezulu kombane kunye nokugqithisa i-OT, kunye nokuphucula ukhuseleko lweepakethi zebhetri.
Inkqubo yolawulo lweebhetri yazisa itekhnoloji yokulinganisela
Okokuqala, masithethe ngengxaki eqhelekileyo yeepakethi zebhetri, ukuhambelana. Emva kokuba iiseli ezizimeleyo zenze ipakethi yebhetri ye-lithium, ukufudumala okubalekayo kunye neemeko ezahlukeneyo zempazamo zinokwenzeka. Le yingxaki ebangelwa kukungangqinelani kwepakethi yebhetri ye-lithium. Iiseli ezizimeleyo ezenza ipakethi yebhetri ye-lithium azingqinelani ngomthamo, ukutshaja, kunye neeparameter zokukhupha, kwaye "isiphumo sebhareli" sibangela ukuba iiseli ezizimeleyo ezineempawu ezimbi zichaphazele ukusebenza ngokubanzi kwepakethi yebhetri ye-lithium yonke.
Itekhnoloji yokulinganisela iibhetri ze-lithium ibonwa njengeyona ndlela ilungileyo yokusombulula ukuhambelana kweepakethi zeebhetri ze-lithium. Ukulinganisela kukulungisa i-voltage yexesha langempela yeebhetri zamandla ahlukeneyo ngokulungelelanisa umsinga wokulinganisela. Okukhona amandla okulinganisela eqinileyo, kokukhona amandla okuthintela ukwanda komahluko we-voltage kunye nokuthintela ukubaleka kobushushu, kwaye kokukhona kungcono ukuziqhelanisa ne-voltage.ibhetri ye-lithium.
Oku kwahlukile kwisixhobo esilula esisekelwe kwihardware. I-lithium battery protector ingaba yi-basic overvoltage protector okanye i-advanced protector enokuphendula kwi-undervoltage, i-temperature fault okanye i-current fault. Ngokubanzi, i-IC yolawulo lwebhetri kwinqanaba le-lithium battery monitor kunye ne-fuel gauge inokubonelela ngomsebenzi wokulinganisela ibhetri ye-lithium. I-lithium battery monitor ibonelela ngomsebenzi wokulinganisela ibhetri ye-lithium kwaye ikwabandakanya nomsebenzi wokukhusela i-IC onokulungiselelwa okuphezulu. I-fuel gauge inezinga eliphezulu lokudibanisa, kubandakanya umsebenzi we-lithium battery monitor, kwaye idibanisa ii-algorithms zokujonga eziphambili ngokusekelwe kuyo.
Nangona kunjalo, ezinye ii-IC zokukhusela iibhetri ze-lithium ngoku zikwabandakanya imisebenzi yokulinganisela iibhetri ze-lithium ngee-FET ezidibeneyo, ezinokukhupha ngokuzenzekelayo iibhetri ezine-voltage ephezulu ezitshajiweyo ngokupheleleyo ngexesha lokutshaja kwaye zigcine iibhetri ezine-voltage ephantsi zitshajiwe ngochungechunge, ngaloo ndlela zilungelelaniseibhetri ye-lithiumUkongeza ekusebenziseni iseti epheleleyo yemisebenzi yokukhusela i-voltage, i-current kunye ne-temperature, ii-IC zokukhusela ibhetri nazo ziqala ukwazisa imisebenzi yokulinganisela ukuhlangabezana neemfuno zokukhusela iibhetri ezininzi.
Ukusuka kukhuseleko oluphambili ukuya kukhuseleko lwesibini
Ukusuka kukhuseleko oluphambili ukuya kukhuseleko lwesibini
Ukhuseleko olusisiseko lukhuseleko olugqithisileyo. Zonke ii-IC zokhuseleko lwebhetri ye-lithium zibonelela ngokhuseleko olugqithisileyo ngokwemigangatho yokhuseleko eyahlukeneyo. Ngenxa yesi sizathu, ezinye zibonelela ngokhuseleko olugqithisileyo kunye nokukhupha umbane ogqithisileyo, kwaye ezinye zibonelela ngokhuseleko olugqithisileyo kunye nokukhupha umbane ogqithisileyo kunye nokutshisa kakhulu. Kwezinye iipakethi zebhetri ye-lithium ezineeseli eziphezulu, olu khuseleko alusanelanga ukuhlangabezana neemfuno zepakethi yebhetri ye-lithium. Okwangoku, kufuneka i-IC yokukhusela ibhetri ye-lithium enomsebenzi wokulinganisela ozimeleyo webhetri ye-lithium.
Olu khuseleko lwe-IC lolwe-primary protection, olulawula ukutshaja kunye nokukhupha ii-FET ukuze ziphendule kwiintlobo ezahlukeneyo zokhuseleko lwempazamo. Olu lungelelwaniso lunokusombulula ingxaki yokubaleka kobushushu bomoya.ibhetri ye-lithiumkakuhle kakhulu. Ukuqokelelana kobushushu obugqithisileyo kwibhetri enye ye-lithium kuya kubangela umonakalo kwiswitshi yokulinganisela ipakethi yebhetri ye-lithium kunye nee-resistor. Ukulinganisela ibhetri ye-lithium kuvumela ibhetri nganye ye-lithium engenasiphako kwipakethi yebhetri ye-lithium ukuba ilinganiswe kumthamo ofanayo nezinye iibhetri ezinesiphako, nto leyo enciphisa umngcipheko wokubaleka kobushushu.
Okwangoku, kukho iindlela ezimbini zokufezekisa ukulinganisela ibhetri ye-lithium: ukulinganisela okusebenzayo kunye nokulinganisela okungasebenziyo. Ukulinganisela okusebenzayo kukudlulisela amandla okanye itshaja ukusuka kwiibhetri ezine-voltage ephezulu/ephezulu ukuya kwiibhetri ezine-SOC ephantsi. Ukulinganisela okungasebenziyo kukusebenzisa ii-resistor ukusebenzisa amandla eebhetri ezine-voltage ephezulu okanye itshaja ephezulu ukufezekisa injongo yokunciphisa umsantsa phakathi kweebhetri ezahlukeneyo. Ukulinganisela okungasebenziyo kunokulahleka kwamandla aphezulu kunye nomngcipheko wobushushu. Xa kuthelekiswa, ukulinganisela okusebenzayo kusebenza ngakumbi, kodwa i-algorithm yokulawula inzima kakhulu.
Ukususela kukhuseleko oluphambili ukuya kukhuseleko lwesibini, inkqubo yebhetri ye-lithium kufuneka ixhotyiswe nge-lithium battery monitor okanye i-fuel gauge ukuze kufezekiswe ukhuseleko lwesibini. Nangona ukhuseleko oluphambili lunokuphumeza ii-algorithms ezikrelekrele zokulinganisela ibhetri ngaphandle kolawulo lwe-MCU, ukhuseleko lwesibini lufuna ukudlulisela i-lithium battery voltage kunye nomsinga kwi-MCU ukuze kwenziwe izigqibo kwinqanaba lenkqubo. Ii-lithium battery monitors okanye ii-fuel gauges ngokusisiseko zinemisebenzi yokulinganisela ibhetri.
Isiphelo
Ngaphandle kweemonitha zebhetri okanye iigeyiji zepetroli ezibonelela ngemisebenzi yokulinganisela ibhetri, ii-IC zokhuseleko ezibonelela ngokhuseleko oluphambili azisekho kukhuseleko olusisiseko olufana nokugqithisa kwamandla. Ngokusetyenziswa okwandayo kweeseli ezininzi.iibhetri ze-lithium, iipakethi zebhetri ezinomthamo omkhulu ziya kuba neemfuno eziphezulu neziphezulu zokukhusela ii-IC, kwaye ukuqaliswa kwemisebenzi yokulinganisela kuyimfuneko kakhulu.
Ukulinganisela kufana nohlobo oluthile lokugcinwa. Itshaja nganye kunye nokukhupha kuya kuba nemali encinci yokulinganisela ukulinganisela umahluko phakathi kweebhetri. Nangona kunjalo, ukuba iseli yebhetri okanye iphakheji yebhetri ngokwayo ineziphene zomgangatho, ukhuseleko kunye nokulinganisela akunakuyiphucula umgangatho wephakheji yebhetri, kwaye ayisiyonto ibalulekileyo kuyo yonke indawo.
